* feat: add Zig language support
Adds a Zig LanguageProvider grounded in @tree-sitter-grammars/tree-sitter-zig 1.1.2.
The grammar's published peerOptional `tree-sitter@^0.22.1` is suppressed via an
npm `overrides` entry that aliases the peer to the bundled `tree-sitter@0.21.x`;
load-time smoke testing confirmed ABI compatibility.
v1 capabilities:
- .zig file detection + Prism syntax mapping
- Top-level + nested function_declaration as Function/Method
- struct/enum/union (anonymous in the grammar — owner name resolved from the
enclosing variable_declaration in class/field/method extractors)
- container_field as struct/union fields and enum variants
- top-level const/var as Variable nodes
- free + member call_expression as @call edges
- @import("./foo.zig") local-file resolution; std and external packages
return empty (no ghost edges)
- pub keyword detection for export checking
- no heritage hooks (Zig has no inheritance; queries never emit @heritage.*)
Generic extractor changes (backward-compatible):
- field-extractors/generic.ts and method-extractors/generic.ts: empty
`bodyNodeTypes` falls back to the type declaration node itself as its own
body container — needed because Zig's struct_declaration directly contains
its container_field children. (The `extractOwnerName` hook this commit
originally introduced now exists upstream; Zig just configures it.)
Out of scope (deferred):
- usingnamespace, build.zig.zon package graph, comptime/anytype
- scope-resolution hooks (emitScopeCaptures, interpretImport, …): Zig is
classified `experimental` and uses the generic fallback resolution path
- cross-package imports (std, deps)
Tests:
- new fixture test/fixtures/sample-code/simple.zig
- Zig describe block in tree-sitter-languages integration test
- simple.zig added to parsing.test.ts fixture-existence list
- Zig added to ingestion-utils detection unit test
- Zig smoke case in parser-loader-abi.test.ts
- Zig grammar registered in the grammar-literal validation gate
* feat(zig): integrate build.zig.zon resolution + Union label from PR 1096
Ports the additive pieces of grgisme's standalone Zig provider PR
(https://github.com/abhigyanpatwari/GitNexus/pull/1096) onto the rebased
provider:
- build.zig.zon `.path` dependency resolution for bare-name
@import("pkg") (parseZigBuildZon / loadZigBuildZon in
language-config.ts, resolveZigImportInternal in import-resolvers/zig.ts,
wired through ImportConfigs.zigBuildZon). `.url` deps and
repo-escaping paths return null cleanly. 13 unit tests.
- `union(enum)` containers now produce `Union` nodes (not Struct):
'Union' added to ClassLikeNodeLabel + CLASS_LIKE_LABELS, the Zig query
tags @definition.union, CONTAINER_TYPE_TO_LABEL maps union_declaration
to 'Union'. The label was already plumbed graph-wide on main.
- /^build$/ entry-point pattern (build.zig).
- zig-basic lang-resolution fixture + resolvers integration test.
Adapted to current main while porting:
- labelOverride relabels container-nested fns Function → Method
(mirrors isKotlinClassMethod); the structure phase no longer derives
Method from the legacy method-extraction path for plain
@definition.function captures.
- IMPORTS/CALLS edges require scope-resolution hooks
(emitScopeCaptures / interpretImport) since the legacy DAG removal;
Zig does not implement them yet, so the integration test documents
that with a skipped import-edge case. The resolver itself is wired
into the resolver factory and becomes live when the hooks land.
Not ported: named-bindings extractor (the legacy namedBindingExtractor
API no longer exists) and the bespoke field extractor (the generic
factory's extractOwnerName / empty-bodyNodeTypes hooks cover Zig).

* feat(zig): scope-resolution hooks — IMPORTS and CALLS edges (Ring 3)
Implements the registry-primary scope-resolution path for Zig, the
prerequisite for cross-file edges since the legacy DAG removal. Adds the
standard per-language stack under languages/zig/:
- query.ts: scope query (containers as Class scopes, blocks, functions),
declarations (container anchors placed on the container node itself so
the def lands in its own Class scope and the name binding auto-hoists
to the parent — populateClassOwnedMembers needs the class-like def
among the class scope's ownedDefs), @import statements (#eq?-gated
builtin), parameter/constructor type bindings, and call/constructor
reference sites. The grammar is required lazily (optionalDependency).
- captures.ts: emitZigScopeCaptures — groups query matches, drops the
plain-variable group for container/import bindings (their dedicated
rules bind the name), and relabels container-nested fns
@declaration.function → @declaration.method (labelOverride parity).
- interpret.ts: namespace-kind imports (const x = @import("…")) and
type bindings — self-parameter convention marks the receiver, Zig
sigils (*, ?, [], error unions, const) stripped from type names while
dotted qualifiers (mod.T) are preserved for Case-3 namespace-prefix
receiver dispatch.
- simple-hooks.ts: parameter bindings stay function-local (Go
rationale), local-over-import merge precedence, bounds-check arity
(always 'unknown' today — no synthesized arity metadata).
- scope-resolver.ts: emit-side wiring; build.zig.zon threads through
loadResolutionConfig into the same resolveZigImportInternal the legacy
resolver config wraps. fieldFallbackOnMethodLookup off (statically
typed). Registered in SCOPE_RESOLVERS.
The resolvers integration test un-skips the import-edge case and gains
CALLS assertions: free call (main → helper) and receiver-bound method
dispatch through a namespace-qualified constructor
(var p = pioneer.Pioneer{…}; p.tick() → main → tick).
* fix(zig): Union is class-like + missing-grammar warning (review pass)
Self-review findings on the Zig branch:
- scope/walkers.ts `isClassLike` and finalize-algorithm's
CALLABLE_OR_TYPE_LIKE did not include 'Union': a `union(enum)`
container's methods got no ownerId from populateClassOwnedMembers, so
method dispatch on union receivers silently dropped. Widened both
sets; the zig-basic fixture gains a Tag method + a CALLS assertion
(main → isEnergy) that fails without the widening (verified by
reverting).
- optional-grammars.ts now lists tree-sitter-zig with an npm `probe`
(it is an optionalDependency, not vendored): users with .zig files
and no prebuild get the standard one-line stderr warning instead of
a silently degraded index.
- Deduplicated the container-method predicate: `isZigContainerMethod`
+ ZIG_CONTAINER_TYPES now live once in languages/zig/captures.ts and
feed both the provider labelOverride and the scope-capture relabel.
- README language matrices: Zig row now claims Type Annotations,
Constructor Inference, and Config (build.zig.zon) — all true since
the scope-resolution hooks landed.
* fix(zig): anchor @declaration.variable to the binding identifier
`(variable_declaration (identifier) @declaration.name)` matched EVERY
identifier child of the node, so `const first = target;` also declared a
phantom local named `target` in the enclosing block. That phantom shadowed
the real function for later references (and starved callable-value-flow
seeds of a target). The `.` anchor pins the pattern to the first named
child — the bound name.
Regression test in resolvers/zig.test.ts pins the capture set.
* feat(zig): callable-value-flow captures + main's per-language conformance gates
Post-rebase catch-up: since this branch forked, main added three "every
registered language must appear here" tests. Each needs a Zig entry:
- callable-value-flow (#2522): Zig now emits `@callable-flow.*` facts via
`synthesizeCallableFlowCaptures` (ZIG_CALLABLE_CAPTURE_OPTIONS in
zig/captures.ts). tree-sitter-zig's `call_expression` carries arguments
as direct children with no wrapper node, which the shared helper could
not decompose, so this adds a language-neutral `extractCallArguments`
hook (mirror of `extractFunctionParameters`; `undefined` = shared path).
Zig joins the provider matrix as 'matrix' with a real assign→copy→
argument→invoke case.
- external-import-conformance (#2953): `@import("std")` beside a decoy
`src/std.zig` resolves to nothing; the decoy stays reachable via the
relative spelling. Zig holds the property (no suffix fallback), so it is
a case, not a KNOWN_GAPS entry.
- import-target-index-reuse contract (#2909): membership-probe-only
fixture (minimumScans: 0, same shape as Rust).
* fix(zig): address gitnexus-check review findings
One commit per the bot's list so each item is easy to check off:
- parser-loader: Zig row gains `userSkippable: true`, so
`GITNEXUS_SKIP_OPTIONAL_GRAMMARS` (=1 or a list naming `zig`) disables it
at analyze time like swift/dart/kotlin — as `optional-grammars.ts` already
documented. Covered in parser-loader-skip-optional.test.ts.
- export-detection: `zigExportChecker` stops at the first declaration it
reaches. A non-`pub` fn inside `pub const T = struct {…}` was reported
exported because the walk continued up to the wrapper.
- import-resolvers/zig: a `.path = "."` dep normalizes to '' and no longer
grows a leading slash (`/src/main.zig` could never match).
- language-config: build.zig.zon parsing strips `//` comments string-aware
(a `//` inside `.url = "https://…"` survives) and matches braces while
skipping string literals, so a commented-out `.path` cannot declare a dep
and a `}` in a comment/string cannot truncate the block.
- method-extractors/configs/zig: the leading `self` receiver is excluded
from `parameters` (Rust parity). Fixing that exposed a worse bug: the
`parameters` node is a plain child of `function_declaration`, not a
`parameters:` field, so `childForFieldName('parameters')` was always null
and every Zig method had no parameters, no receiver and `isStatic: true`.
One `zigParameterList` helper now feeds all three readers.
- variable-extractors/configs/zig: container (`struct`/`enum`/`union`) and
`@import` bindings are skipped via the same predicate the scope captures
use (`isZigContainerOrImportBinding`), instead of the comment merely
claiming they were.
- tree-sitter-languages.test.ts: the "missing grammar" case now forces the
absent-binding path through the loader's runtime opt-out on a fresh module
instead of passing vacuously when the package is installed.
New: test/unit/zig-extractors.test.ts (exports, receiver/parameters,
variable guard); zig-import-resolver.test.ts gains the `.` dep, comment and
brace cases.
The `createFieldExtractor` heads-up needs no change: the added branch is
unreachable for every existing config (none has empty `bodyNodeTypes`).
* fix(zig): address second gitnexus-check review pass
- import-resolvers/zig: `..` above the repository root now returns null
instead of aliasing a same-named root file (`../bar.zig` from `main.zig`
is not `bar.zig`); the stale "extension is stripped and re-added" comment
is corrected to what the code does.
- variable-extractors/configs/zig `extractType`: read the `type:` field only.
The positional fallback returned the INITIALIZER of `const f = target;`
as its type and gave up on compound annotations (`*Foo`, `?[]const u8`).
The comment claiming 1.1.2 has no `type` field on variable_declaration
was wrong (verified by AST dump) — and it is what led the review to
suspect the callable-flow `extractAssignment` callback, which was
already correct for `extern var f: T;`.
- receiver detection: only a FIRST parameter named `self` is the receiver.
`emitZigScopeCaptures` tags first-position parameters
(`@type-binding.first-parameter`), `interpretZigTypeBinding` requires the
tag as well as the name, so `zigReceiverBinding` no longer turns
`fn f(a: u32, self: T)` into an instance method.
- resolvers/zig.test.ts: both suites `describe.skipIf(!zigAvailable)`
(Swift/Dart pattern) — the grammar is an optionalDependency.
- tree-sitter-languages.test.ts: the Zig parsing case gates on
`isLanguageAvailable` instead of a catch-all `return`, so an installed
grammar that fails to load fails the test; comment no longer calls Dart
and Swift npm optionalDependencies (they are vendored).
- test/helpers/literal-collectors: `DIR_LANG` gains `zig`, so literals under
`languages/zig/**` are validated against the Zig grammar alone rather than
against every grammar.
- walkers.ts `isShapeLike` doc: Union IS included (via isClassLike, wired by
Zig's union member container); Typedef remains the only deferred one.
- language-config `ZigBuildZonConfig.pathDeps` doc: values are the raw
`.path` strings; the resolver normalizes.
Tests: zig-import-resolver (+1), zig-extractors (+3).
* fix(zig): address third gitnexus-check review pass
- language-config `parseZigBuildZon`: the `.dependencies = .{` header and
the per-entry `.<name> = .{` headers are matched only OUTSIDE string
literals (per-offset string mask + `matchZonHeader`). A `.name` or
`.description` value spelling `.dependencies = .{ .fake = .{ .path = … } }`
used to be taken as the block and returned the fake dep instead of the
real top-level one.
- import-resolvers/zig: an absolute import (`@import("/foo.zig")`) returns
null. The path walker skipped every empty component, so the leading `/`
vanished and `/foo.zig` resolved as importer-relative `src/foo.zig` — an
in-repo edge for an import Zig rejects as outside the module path.
- tree-sitter-languages.test.ts: the Zig parsing case gates on the PACKAGE
being installed (`createRequire().resolve`, minus a deliberate
`GITNEXUS_SKIP_OPTIONAL_GRAMMARS` opt-out), not on `isLanguageAvailable`,
which is false for absent AND for installed-but-broken bindings — so a
load failure (ABI mismatch, bad export) now fails the test instead of
skipping it, as the comment already claimed.
- walkers.ts `isShapeLike` doc: `Union` sits in `isClassLike` because that
is the label set the ownership walkers consult, not because unions
inherit — Zig has no inheritance and no heritage hooks. The previous
wording ("inheritance-capable owner") said otherwise.
- Not re-fixed (already addressed in the second pass, findings carried
over): "receiver = any parameter named self" — `interpretZigTypeBinding`
only sources a first-position parameter as `self`; `zigReceiverBinding`'s
doc now states that invariant. "`DIR_LANG` has no zig entry" — it does.
Extended one level out: `BASENAME_LANGS` (`zig.ts`) and `PREFIX_LANGS`
(`ZIG_`) map to the Zig grammar too, so extractor configs and the
export-detection set are validated against Zig alone. That immediately
caught a dead `childForFieldName('parameters')` in
method-extractors/configs/zig `zigParameterList` (there is no such field;
the named-child lookup was already the one doing the work) — removed.
Tests: zig-import-resolver (+2: absolute path, header inside a string);
both fail on the previous code.
* fix(zig): address fourth gitnexus-check review pass
- language-config: `parseZigBuildZon` only accepts a `.path` that is a
DIRECT field of a dependency entry. Nested blocks inside the entry body
are blanked (string-aware, offsets preserved) before the `.path` regex
runs, and a match starting inside a string literal is rejected, so
`.dep = .{ .url = "…", .meta = .{ .path = "x" } }` no longer becomes a
path dep. Regression test in zig-import-resolver.test.ts (fails on the
previous code).
- tree-sitter-languages test: the "grammar is absent" case now drives the
loader's real `source.load()` catch branch — `node:module` is stood in
with a `createRequire` whose require throws MODULE_NOT_FOUND for
`@tree-sitter-grammars/tree-sitter-zig` and delegates everything else —
instead of the `GITNEXUS_SKIP_OPTIONAL_GRAMMARS` opt-out, which has its
own test. It also asserts the opt-out flag is NOT set and that other
grammars still load (non-fatal optional failure).
Not re-fixed:
- "Return type is read from the wrong tree-sitter field": tree-sitter-zig
1.1.2 has NO `return_type` field on function_declaration — the type after
`)` is the `type` field (AST dump: `builtin_type "i32" field=type`; the
proposed `childForFieldName('return_type')` is null for every function).
A pin test in zig-extractors.test.ts asserts both the grammar fact and
that `returnType` is extracted (`void`, `!*Counter`).
- "`DIR_LANG` has no zig entry": it does (added in the first pass and
answered again in the third); the finding is carried over unchanged.
* fix(zig): address fifth gitnexus-check review pass
- tree-sitter-languages test: the Zig "functions, structs, enums, and
imports" case now asserts the `import.source` capture for
`const std = @import("std");` (the fixture's only import), so a query
change that drops Zig import matching fails it instead of passing
unchanged.
Not re-fixed:
- "Return type is read from the wrong tree-sitter field": carried over from
the fourth pass unchanged. tree-sitter-zig 1.1.2 has no `return_type`
field on function_declaration; the return type IS the `type` field, and
the pin test added in the fourth-pass commit
(zig-extractors.test.ts, `childForFieldName('return_type')` is null,
`returnType` = `void` / `!*Counter`) proves it.
- "`DIR_LANG` has no zig entry": carried over unchanged for the third time;
the entry exists since the second-pass commit.
* feat(zig): export fn visibility, opaque containers, named test blocks, member ownership
Ports the parts of upstream PR #305 (closed, unmerged) that our Zig
provider lacked, plus two gaps found while porting.
- `export fn` / `export var` (C-ABI linkage, never `pub`) are exported;
the pub/export predicate is now shared by the export checker and the
method/variable extractors' visibility (`hasZigVisibilityKeyword`).
- `const H = opaque { … }` is a Struct-labelled container (it may own
methods, never fields) in both the structure queries and the scope
query; ZIG_CONTAINER_TYPES is the single source for the extractor
configs.
- `test "name" { … }` blocks are Function nodes named by the string
node WITH quotes, so `test "add"` beside `fn add` cannot merge onto
Function:<file>:add; `test_declaration` joins FUNCTION_NODE_TYPES and
the Zig method config names it in the enclosing-function walk, so
calls inside a test attribute to the test. Anonymous `test {}` and
decl-tests `test add {}` are scopes without a node (an empty-name hook
result stops the walk instead of falling through to the identifier of
the function under test).
- Empty container bodies (`struct {}`, `opaque {}`) no longer mint a
nameless Property: tree-sitter-zig 1.1.2 recovers them as a
container_field with a MISSING identifier; #not-eq? guards in both
queries and the field extractor drop it.
- Owner walk (`findEnclosingClassInfo`): an anonymous container bound
by the enclosing `variable_declaration` takes the binding identifier,
same shape as the Go `type_spec` branch. Before this NO Zig member
had an owner — zero HAS_METHOD / HAS_PROPERTY edges for Zig.
Not ported from #305, deliberately: `builtInNames` (a bare-name call-site
drop filter; `alloc`/`free`/`append`/`print` are the most common user
method names in Zig and `std.*` receivers are already external via the
import binding), `usingnamespace` (removed in Zig 0.15), `@cImport`,
`build.zig` ignore, and the web-app changes.
* test(zig): absent-grammar case owns GITNEXUS_SKIP_OPTIONAL_GRAMMARS
The loader parses the opt-out variable lazily once per module copy, so
under `GITNEXUS_SKIP_OPTIONAL_GRAMMARS=zig` (or `all`) — a supported way
to run — the fresh loader took the opt-out branch and the "not the
opt-out path" assertion failed before the absent-binding path ran.
Clear the variable for the fresh module and restore it in `finally`,
instead of returning early: the branch stays exercised in every
environment. Verified: fails on the previous code under `=zig`, passes
with and without the variable now.
* fix(zig): declare the Union relation pairs — analyze aborted on any union
`gitnexus analyze` exited 1 on every Zig repository that declares a
`union` (including the zig-basic fixture itself): the member-ownership
commit made `union_declaration` a MEMBER_OWNER, so HAS_PROPERTY /
HAS_METHOD edges are emitted FROM a Union node, but `Union` was not in
LINKABLE_LABELS, so the schema's scope-bridge cross product never
generated a `FROM Union` pair and LadybugDB rejected the edge
(`labelPair: "Union|Property"`). Resolver tests stayed green because
they never write to the DB.
- `Union` joins LINKABLE_LABELS (also bridges `Tag{…}` constructor
references); the three hand-written `→ Union` target pairs move to the
generated half, per the STRUCTURAL_PAIR_DDL rule.
- structural-pair-coverage gains an optional-grammar corpus with
zig-basic (`Union|Property`, `Union|Method` sentinels), skipped when
the grammar is absent.
- Rust `union_item` note updated: the three gates it cited are widened.
Note for reviewers: the DDL fingerprint changes (#2808), so existing
indexes are rebuilt on next analyze.
* feat(zig): resolve path deps through the dep's build.zig and src/root.zig
The bare-name resolver only knew `src/<name>.zig` and `src/main.zig`.
`zig init` has written `src/root.zig` for libraries since 0.12, so the
default library layout never resolved. Now: the root the dep's own
build.zig declares (`b.addModule("<name>", .{ .root_source_file =
b.path("…") })`, name-matched module first), then src/root.zig,
src/<name>.zig, src/main.zig. `normalizeZigDepPath` is shared by the
loader and the resolver.
* feat(zig): Const/Variable defs, member imports, receiver typing, generic type constructors
Coverage gaps found by indexing idiomatic Zig against the branch:
- Const / Variable nodes: ZIG_QUERIES had no @definition.const /
@definition.variable, so `pub const VERSION`, error sets and type
aliases were absent and zigVariableConfig never ran. Rules are gated on
the literal `const` / `var` keyword — tree-sitter-zig 1.1.2 parses
statement assignments (`x = 5;`, `x += 1;`, `_ = expr;`) as keyword-
less `variable_declaration`s, and the scope query minted a phantom
local per assignment and one `_` per discard. Container and @import
bindings are skipped via `shouldSkipDefinitionCapture`.
- Imports: `const X = @import("x.zig").X` (named / alias), `const X =
ns.X` where `ns` is an @import binding of the file (promoted to a
named import), and `pub usingnamespace @import(...)` (wildcard, with
`expandsWildcardTo`). All three lost the file-level IMPORTS edge.
- Receiver typing: `var x: T = undefined` / decl literals `const x: T =
.init()` (annotation), `var c = T.init()` / `mod.T.init()` (call
return), `List(u8){}` (instantiation literal); `normalizeZigTypeName`
drops the comptime argument list.
- Generic type constructors `fn List(comptime T: type) type { return
struct {…}; }`: the returned container is a Struct/Union/Enum named
after the fn, owns its members (HAS_METHOD / HAS_PROPERTY), binds in
the module scope beside the Function def, and is emitted ahead of it
so a named import binds the type.
- `export` vs `pub`: `visibility` is now `pub`-only (Zig-module fact);
`isExported` keeps `pub|export` (visible outside the unit, as C's
external linkage). `export fn` without `pub` is not reachable from
other Zig files.
- Extractor configs share `zigContainerName`; ast-helpers' owner walk
learns the type-constructor shape.
Tests: zig-idioms fixture (10 resolver cases), extractor/interpret unit
cases for each rule.
* fix(zig): address sixth gitnexus-check review pass
- Windows absolute `.path` deps (`C:\x`, `C:/x`) return null from
`normalizeZigDepPath` like POSIX ones; a `/`-only check let them
through as repo-relative.
- `parseZigBuildZon` accepts the `.dependencies = .{` header only at
brace depth 1 (a direct field of the file's `.{`), so a same-named
field nested in an earlier struct cannot hijack the block.
- `importsExecuteWhereWritten: false` on the provider: `@import` is
compile-time name lookup (as C `#include`, Rust `use`); a body-level
`@import` is no longer marked `runsOnlyWhenCalled`.
- Namespace imports record the MODULE as `importedName`
(`zigModuleNameOf`: last path segment without `.zig`), per the shared
contract; the local handle stays `localName`.
- Keyword-less `<ident> = @import(…)` (`_ = @import("x.zig")` in a test
block) is a `side-effect` import: file edge, no binding. Only
`const`/`var` declarations bind a name or feed alias promotion.
- `extractZigFunctionName` doc: an empty name is falsy, so the enclosing-
function walk skips the test node and continues to the File; it does
not "end" there.
Not re-fixed: "DIR_LANG has no zig entry" — carried over for the fourth
pass in a row; `test/helpers/literal-collectors.ts` has had `zig` in
`DIR_LANG` (line 91) and `BASENAME_LANGS` since the second-pass commit.
Regression tests: absolute-path spellings, nested `.dependencies`
decoy, namespace/side-effect interpretation, function-scoped `@import`
not deferred (all four fail on the previous source).
* fix(zig): address seventh gitnexus-check review pass
- The scope query's `@import` binding rules are keyword-gated (`"const"` /
`"var"`, first-child anchored) like every other binding rule, and the
keyword-less `<ident> = @import(…)` statement has its own
`@import.side-effect` rule. Tree-sitter queries cannot express "no
keyword child", so that rule also matches the keyword shapes and
`emitZigScopeCaptures` drops those (they are the binding rules'
matches). Behaviour is unchanged from the sixth-pass fix — the existing
side-effect test covers it — the query text now carries the guard the
finding asked for.
Not re-fixed: "DIR_LANG has no zig entry" — fifth pass in a row;
`test/helpers/literal-collectors.ts` has had `zig` in `DIR_LANG` since
the second-pass commit. Left for a human reviewer to close.
* fix(zig): resolve @import of the repo's own build.zig modules (F3)
Bare-name imports were resolved through build.zig.zon path deps only, so
the module a repo's ROOT build.zig declares for itself —
`b.addModule("lightpanda", .{ .root_source_file = b.path("src/lightpanda.zig") })`,
imported by name from 378/567 Lightpanda files — never produced an IMPORTS
edge, and nothing reached through `lp.X` resolved. A repo with a build.zig
but no build.zig.zon got no resolution config at all.
- language-config: `parseZigRootModules` (static scan of the root build.zig:
`addModule("<name>", …root_source_file = b.path("<p>.zig")…)`, and
`createModule`/`addModule` bindings named via `addImport("<name>", m)` or
`.imports = &.{ .{ .name, .module = m } }`; generated / `.url` / computed
modules are skipped) → `ZigBuildZonConfig.rootModules`.
- `loadZigBuildZon` → `loadZigBuildConfig`: reads the zon AND the root
build.zig; null only when neither contributes.
- resolver: root modules are consulted before path deps; std/builtin/root
still never resolve.
- fixtures: zig-idioms gains a Lightpanda-shaped root module (+ decoy
`addOptions().createModule()`); new zig-rootmodule (build.zig, no zon).
Corpus (Lightpanda): IMPORTS 3014→3389 (378 edges to src/lightpanda.zig,
was 0), CALLS 13885→13989, ns.f() 79.3%→83.3%,
param.m() type=ns-qualified 43→46/417.
* fix(zig): import every @import in expression position; resolve @import("x").f()
Both query sets only saw `@import` as the value of a const/var or under
`usingnamespace`, so an @import in any other position produced no file
edge: Lightpanda's `pub const Interfaces = .{ @import("a.zig"), … }`
registration table (288 modules), call arguments
(`CounterEnum("size", @import("ArenaPool.zig").BucketSize)`), comparison
operands (`JsApi == @import("x.zig").JsApi`) and member-call receivers
(`try @import("dump.zig").root(...)`) — 417 of 3,401 in-repo import pairs
had no IMPORTS edge, and the 80 inline-receiver calls resolved 0 times.
Scope query: a catch-all `@import.inline` rule matches every `@import`
builtin; `emitZigScopeCaptures` drops the ones a binding rule (or the
keyword-less side-effect rule) already claimed (by string-node id) so a
bound import is never doubled, emits the rest as side-effect imports once
per distinct source per file, and binds a member-call receiver as a
namespace import whose local name is the builtin's own text — the
`@reference.receiver` text on that call is identical, so the shared
namespace-receiver lookup (Case 1) resolves the member in the imported
module.
ZIG_QUERIES: the three variable_declaration/usingnamespace-anchored
`@import` rules collapse into the same single builtin rule (the structure
phase only skips import matches; one match per builtin keeps
tree-sitter-languages' exact-capture assertion intact).
Lightpanda corpus (zig-corpus-check, before → after): IMPORTS 3014 → 3426,
in-repo pairs missing 417 → 5 (4 under a default-ignored `cache/` dir, 1 a
commented-out import the census regex counts), `@import(..).f()` 0/80 →
72/80 (the 8 left are `@import("root")` and non-import builtins the census
mislabels), CALLS 13885 → 13959; every other line unchanged.
* feat(zig): model file-structs — a file with top-level fields is a Struct named after the file
In Zig every file is a struct; one that declares top-level fields is an
instantiable type whose name is the file stem (`Page.zig` declares `Page`,
`@typeName` agrees), and its top-level `fn`s taking `self` are its methods.
Lightpanda spells 413 of 567 files this way and, before this, `page.getArena()`
on a `page: *Page` parameter resolved 23 of 993 times (2.3 %) — `impact` on
`Page.getArena` reported 0 callers for 159 call sites, and 2,395 top-level
fields were ownerless Property nodes.
Definition phase: `((source_file (container_field …)) @definition.struct)` +
the class extractor names it from the file path (`zigContainerName(source_file,
filePath)`); top-level fns/fields are owned through the new
`LanguageProvider.resolveFileTypeOwner` hook (consulted by
`findEnclosingClassInfo` when the walk reaches the tree root, and by the
method/field extractors' owner lookup) — ids become `Method:<file>:Page.getArena#0`
/ `Property:<file>:Page.session` with HAS_METHOD / HAS_PROPERTY edges.
Scope phase: `emitZigScopeCaptures` emits a Class scope over the whole file
(same range as the Module scope, nested under it — the pair `canParentScope`
already admits) plus a Struct def anchored on it; member NAME bindings are
hoisted back to the Module scope by `zigBindingScopeFor` so `Page.init()`
(namespace member) keeps working, while ownedDefs stay in the Class scope so
`populateClassOwnedMembers` stamps the owner. The file-level `const Page =
@This();` alias no longer mints a Const (it would shadow the Struct); `@This()`
aliases in type position (`self: *SigHandler` in Sighandler.zig, nested
`Self`) are rewritten to the container name so receivers resolve. A namespace
import of a `.zig` file gets a NAMED twin of the file stem so `x: *Page` in the
importer binds the type as well as the module.
Shared, additive: `resolveFileTypeOwner` hook; `filePath` threaded to
`ClassExtractionConfig.extractName` / `extractOwnerName`; nameless
`definition.struct` passes `getLabelFromCaptures` like `definition.class`
already did (extractor synthesizes the name).
Lightpanda corpus (zig-corpus-check): param receivers typed by a file import
23/993 → 993/993; `self.m()` 99.2 → 100 %; annotated locals 11.6 → 23.2 %;
CALLS 13,885 → 15,689; HAS_METHOD 1,477 → 8,003; ownerless Property 2,395 →
276; Function/Method 8,378/1,518 → 2,562/7,330; no row regressed.
Fixture `zig-filestruct` (Page/Session/Sighandler/util) + unit tests pin the
shape, the stem naming, the alias rewrite, the namespace twin and the
unchanged namespace-file behaviour.
* test(zig): expression-position import case sees the file-struct type twin
* fix(zig): stop reading member calls `x.f(arg)` as direct calls named `f`
tree-sitter-zig spells `field_expression` as `object:`/`member:`; the shared
callable-flow reader only knew `property`/`field`/`method`, so every Zig
member call collapsed to a DIRECT call named after the member and the
solver fanned each argument out to every same-named callable
(4,761 cap warnings on Lightpanda, `Global.deinit -> Global.deinit`
self-loops through `pub const release = deinit;`).
Shared (grammar-neutral, receiver-gated):
- `memberParts` also reads `member` (only C/C++ `offsetof_expression` and
JS `class_body` expose that field, without a receiver field).
- A member call is a field-stored-callable invoke only when a MEMBER store
(`o->run = handler`, `self.f = target`) or a declared callable-typed field
is visible — a same-named plain binding no longer gates it.
- `direct-callee-name` requires a direct designator: `.init(x)`,
`' '.join(x)`, `string.Join(x)` name no callee to seed by simple name.
Zig: formals are numbered without the leading `self`, so `r.run(target)`
joins `cb` and yields `Runner.run -> target`.
Goldens for python/csharp regenerated: the only drift is the dropped
`direct-callee-name` on `' '.join(...)`, `text.strip().ljust(...)`,
`string.Join(...)`.
Lightpanda: cap-warnings 4761 -> 2, cvf self-loops 10 -> 0,
CALLS 13885 -> 13857 (28 removed, all callable-value-flow: 10 self-loops,
17 same-name fan-out, 1 lost `on -> TypeErased.start`; +1 correct
`Arena.alloc -> allocator`).
* fix(zig): bind container field types so `self.field.m()` resolves (F5)
A container's field types were never bound on its Class scope: the scope
query's `container_field` rule captured only the name, and
`emitZigScopeCaptures` synthesized no `@type-binding.field` group. The
compound resolver reads member types from that scope
(`typeOfMemberOnClass` → `classScope.typeBindings.get(field)`), so
`self.session.name()`, `self.counter.incr()` — Lightpanda's dominant
cross-object call shape — resolved 9 of 2803 times (0.3 %).
- query.ts: capture `type: (_)? @declaration.field-type` on
`container_field` (enum variants have none).
- captures.ts: per typed field, push a `@type-binding.field` group (name =
field, type = the type text, `@This()` aliases rewritten to the container
name like parameter types); anonymous inline containers are skipped. The
binding lands on the container's Class scope — the file's Class scope for
a file-struct — since `zigBindingScopeFor` hoists only declaration names.
- query.ts/captures.ts: `const page = self.page;` / `var s = self.session;`
one-level field aliases become `@type-binding.alias` bindings whose "type"
is the RHS path; the resolver's member-alias branch re-resolves it as a
receiver chain. Import aliases (`const Counter = counter.Counter;`) are
dropped — they are named imports.
- interpret.ts: `@type-binding.field` → 'annotation',
`@type-binding.alias` → 'assignment-inferred' (an annotation on the same
binding wins).
Corpus (Lightpanda, zig-corpus-check): self.field.m() 11/2803 (0.4 %) →
1433/2803 (51.1 %); ident.m() bound=local-field-access 29/1902 (1.5 %) →
307/1902 (16.1 %); chain.m() 146/5022 (2.9 %) → 642/5022 (12.8 %);
CALLS 15838 → 18066. self.m() / free f() / ns.f() unchanged.
Tests: unit (zig-extractors) — one @type-binding.field per typed field with
sigils stripped and aliases rewritten; the binding hosted on the container's
Class scope (file-struct: the file's Class scope, not Module) with the
written spelling as declaredSpelling; field aliases bound to the RHS path
and never for import aliases. Integration (zig-idioms `holder.zig`,
zig-filestruct `Page.zig`): `viaField → incr` ×2 into counter.zig,
`viaAlias → get/twice`, `sessionName → name` / `sessionLabel → name` into
Session.zig. All fail without the change. The optional-payload capture
`if (self.opt) |c| c.incr()` is not asserted (F6).
* fix(zig): `pub const X = @import(…)` at file scope republishes X (reexportsName)
Lightpanda's `lightpanda.zig` is one long list of `pub const Arena =
@import("Arena.zig");`, and most files name their types through it (`const
lp = @import("lightpanda"); const Arena = lp.Arena;`, `arena: *lp.Arena`).
The scope side treated those bindings as plain imports of the hub file, so
the hub never published the names it re-exports and a third file's `const
Arena = lp.Arena;` (promoted to a named import of `Arena` from the hub) found
nothing.
`emitZigScopeCaptures` now marks named/alias import groups whose declaration
is a file-level `pub const` — the `@import(...).X` form, the alias promotion
`pub const Bar = ns.Bar`, and the file-struct type twin of `pub const Arena =
@import("Arena.zig")` — and `interpretZigImport` sets the shared contract's
`reexportsName: true` on them (the Python `__init__.py` shape, consumed by
`buildReexportClosures`). Private and fn-local bindings stay unflagged.
Not covered here: a receiver ANNOTATED with the dotted hub path (`arena:
*lp.Arena`) — Case 3 of the receiver-bound pass looks the member up with
`findExportedDef`, which only sees locally declared names; following
re-exports there is a shared change left for a follow-up.
* fix(zig): type receivers through `const X = <type expr>;` aliases (F7)
`const LocalAlias = Local;`, `const T2 = Thing;` (alias of an alias/import)
and `const B = util.List(u8);` (an INSTANTIATED generic type constructor)
were plain `@declaration.variable` bindings, so `LocalAlias.mk()`,
`var l = LocalAlias.mk(); l.go()`, `T2.make()`, `B.init()`, `B{}` and
`var x: B` all typed nothing (review repro r3-flow b1..b9; Lightpanda:
`pub const Proto = HtmlElement;` x68, `const Allocator = std.mem.Allocator`
x104, `pub const KeyIterator = GenericIterator(...)`, fn-local
`const R = ...(...)`).
Model: a `@type-binding.alias` binding of the alias NAME to the value's type
text — Rust's `let x = y` / JS's `const B = Foo`, source
'assignment-inferred' — NOT a TypeAlias def. Reasons: (1) the shared
machinery already chains typeBindings (`followChainedRef` in the extractor,
`followChainPostFinalize` after propagation), so `var l = LocalAlias.mk()`
and `var x: B` reach the target through the alias with no new shared code;
(2) nothing shared follows a `TypeAlias` def to its target — `isShapeLike`
only makes the alias itself a member owner (TS object-type aliases) — so a
relabel would have needed language-named shared code; (3) graph node ids
are UNCHANGED: every alias stays `Const:<file>:X`. `normalizeZigTypeName`
already drops the comptime arguments, so `util.List(u8)` binds `util.List`
and resolves through the namespace import (Case 3). The identifier /
member shapes also take `var` (`var cur = orig; cur.go()` — the cursor
idiom, same binding as Rust's `let x = y`).
Heuristic, stated as such: a CALL value is kept only when the callee's last
identifier is TitleCase (Zig's naming convention for types), because the
grammar cannot tell `util.List(u8)` from `util.makeThing()` and the latter
belongs to the call-return rules; the call-return group is dropped for the
same TitleCase shape so the two never race on match order. Import bindings
(`const Stack = @import("x.zig").Stack`), promoted namespace-member aliases,
enum/decl literals (`.foo`) and the `type:` annotation of
`var b: T = undefined;` are excluded.
Not done: the two-hop `pub const bridge = js.Bridge(T); bridge.accessor()`
chain. `js.Bridge` is a Function that RETURNS `bridge.Builder(T)` (a call,
not a container), so the alias binds `js.Bridge`, Case 3 finds a Function
with no members in js.zig, and Case 3b is skipped for a namespace head.
Following that hop needs a namespace-member return-type route in shared
code (or a Zig `resolveQualifiedReceiverMember` hook that re-implements
member lookup without the model); left for a follow-up.

* fix(zig): one alias rule set — F7's alias rules subsume F5's field-access alias rules
* fix(zig): type locals through try/catch/orelse, return types and payload captures
F6 of the gitnexus-check review. Three gaps in the value flow that types a
local receiver, all measured on Lightpanda:
1. `@type-binding.call-return` needed the `call_expression` as the DIRECT
value child, so `const p = try Page.init(…)` (2,551 sites), `… catch
return` (410) and `… orelse return` typed nothing. The rule is now one
keyword-gated declaration match; `emitZigScopeCaptures` unwraps `try`,
`catch`, `orelse` and parentheses (`zigUnwrapValue`) and decides what the
value types (`zigCallReturnTypeOf`): a module-level receiver still names
the type (`Counter.init()` → Counter, Rust `Foo::new()`); a free call
binds the callee name (`makeThing`); a member call on a fn-LOCAL receiver
(parameter / local / payload — Zig forbids shadowing, so "declared in the
fn" is exact) binds the compound `node.asElement()` the shared resolver
walks to the method's return type — instead of typing `el` as `Node`. A
TitleCase callee (`List(u8)`) is a type constructor and binds nothing.
2. No `@type-binding.return` existed. `fn make() !*Thing` now binds
`make ↦ Thing` in the enclosing scope (Module for free fns, the container's
Class scope for methods, where the compound resolver reads it). Builtins,
`type`, `@TypeOf(…)` and comptime type parameters (`?*T`) bind nothing;
`@This()` / `Self` returns name the container. `normalizeZigTypeName` now
strips the error union BEFORE the payload's sigils, so
`Allocator.Error!*Page` → `Page` (it used to leave `*Page`).
3. Payload captures had no binding at all. `populateZigRangeBindings`
(registered as `populateRangeBindings`) types `for (items) |it| / |*it|`,
`for (items, 0..) |it, i|`, `if (opt) |v|`, `if (call()) |v|`,
`while (it.next()) |x|` from the SUBJECT's written type minus one layer
(`[]T` element, `?T` payload) — declining when the layer is not visible
(`ArrayList(T)`) — and the same projection for `const t = items[i]` /
`opt.?` / `ptr.*`. `catch |err|` and `switch` prongs are skipped.
Corpus (Lightpanda, gate before → after): CALLS 15838 → 17853;
`ident.m() bound=local-try/catch/orelse` 11/1298 → 584/1298;
`local-call` 159/1282 → 398/1282; `payload` 82/1085 → 233/1085;
`other-recv:call_expression` 5/991 → 457/991; `local-other` 271 → 364;
`self.m()` 100 %, `free f()` 97.5 %, `ns.f()` 83.4 % unchanged; nothing down.
Not covered: `const t = ns.f()` (a namespace fn's return type across files —
Case 3 has no path from a namespace head to a callable's return binding),
and expression receivers (`items[i].run()`, `o.?.run()`).
* fix(zig): resolve leftover fixture merge markers (Page.zig)
* fix(zig): reconcile F6 value inference with F7 aliases and F5 field bindings
- A fn-local TitleCase receiver (`const R = generic.List(u8); var l =
R.init();`) is a type alias (F7), not a value local: `R.init()` names the
type `R` like `Counter.init()` does at module level, so `l` chains
R → util.List → push. F6's local-receiver rule now excludes TitleCase heads.
- The F6 unit helper only collects the value-inferred / return kinds it
owns; F5 field and F7 alias bindings for the same names are asserted in
their own suites.
* fix(zig): give function-local and anonymous containers an identity (F8)
`const R = struct {…}` declared inside a fn (Lightpanda's reflection.zig
has ~20, one per builder) all collapsed onto one `Struct:<file>:R` with one
`R.get`; anonymous containers (`std.sort.pdq(…, struct { fn lessThan … }
.lessThan)`, `const byte_size = struct { fn it … }.it;`, `?struct { min,
max }` field types) had no identity at all, so their fns were OWNERLESS
Methods (`Method:<file>:lessThan#3`) that collided across a file.
`zigContainerName` now yields the graph IDENTITY on both phases:
- function-local named: `<enclosing callable>$<name>` — `Reflect.string$R`
(Java local-class `$` chain; `populateClassOwnedMembers` leaves it whole);
- anonymous: `<host>$<ordinal>` — `build$1`, `Outer$1`, `Page$1`
(javac's `Outer$1` numbering per host, in source order);
- a `test` host is keyed `test@L<line>` (its string does not survive the
class extractor's qualified-name normalization).
`zigContainerBindingName` keeps the spelling code writes (`R`) for scope
bindings and `@This()` alias rewrites (`@declaration.binding-name`).
Structure phase: bare `(struct|enum|union|opaque_declaration)` rules mint the
local/anonymous nodes via the class extractor; `shouldSkipDefinitionCapture`
keeps exactly one rule per container (`zigContainerAnchor`); a new
grammar-neutral `resolveContainerTypeOwner` provider hook lets the shared
owner walk name a container from context, so `Method:<file>:Reflect.string$R
.get#0` and its HAS_METHOD source agree by construction. Scope phase: the
wrapper group splits name/binding-name for locals and anonymous containers
get synthesized `@declaration.<kind>` defs (`is-synthetic`).
Lightpanda: ownerless Methods 14 → 0, fns without a node 55 → 0, ownerless
Properties 276 → 5, HAS_METHOD 8003 → 8074, HAS_PROPERTY 7275 → 7403,
CALLS 15838 → 15857, Struct 1905 → 2199; no resolution bucket dropped.
* fix(zig): re-add the implicit receiver on the call side so both method-call spellings reach the callback formal
`extractFunctionParameters` sliced the leading `self` off the formals, which
lined up `r.run(target)` (target@0 ↔ cb@0) but lost the explicit spelling
`Runner.run(&r, target)` (&r@0, target@1 ↔ cb@0): the callback never joined
its formal and `run → target` was missing (PR #1432 review by koriyoshi2041).
Formals are numbered once per function while the receiver differs per call
shape, so the fix lives in `extractCallArguments`: keep `self` as formal 0
and prepend the receiver as actual 0 when the callee is a member call on a
VALUE receiver — chain head is a fn-local name that is not TitleCase, the
same value-vs-type rule F6 uses. Namespace / type / decl-literal receivers
(`Runner.init(cb)`, `helpers.apply(cb)`, `List(u8).init`, `.init(cb)`) get
no prepend. Known residual gap, documented: a module-level value receiver
(`global_runner.run(cb)`) is not fn-local and still misses.
Tests: the F2 integration case now asserts both spellings plus a namespace
call; the unit contract pins `self@0, cb@1` and the per-call actual index.
* fix(zig): address eighth gitnexus-check review pass
- Named dependency modules: `parseZigBuildModuleRoots` scanned
`addModule("<name>", .{ … })` with a `[^}]*` regex, so a nested field
before `.root_source_file` (`.imports = &.{ .{ … } }`) ended the match
at the inner `}` and demoted the module to an unnamed fallback — the
first exe/lib root in the file then answered `@import("<name>")`. The
named lookup now walks the balanced `addModule(…)` argument list
(same scanner as `parseZigRootModules`, comment-stripped, string-aware);
the unnamed fallbacks are unchanged. Regression test in
`zig-import-resolver.test.ts`.
- Type-position `@import`: `var x: @import("m.zig").T = undefined;` was
read as an import binding of `x` on both sides — the query rules match
the `type:` child like a value, and `isZigContainerOrImportBinding`
scanned every named child — so `x` was never declared and became a
named import of `T`. The helper now skips the `type:` field, and
`emitZigScopeCaptures` drops binding-rule matches whose `@import` sits
in the annotation (`isZigTypePositionImport`) without claiming the
source, so `x` binds as a variable and the file edge survives as a
side-effect import. Regression tests in `zig-extractors.test.ts`
(variable extractor + scope captures).
- Union in the class-capture skip guard: the parse-worker's inline
class-like predicate lacked `Union`, so a `Union` definition bypassed
`shouldSkipClassCapture` unlike every other `ClassLikeNodeLabel`.
Added the label; no Zig behavior changes (Zig defines no skip hook), so
no test.
- File-owned method ids in `findEnclosingFunctionId`: the arity lookup
used `findEnclosingClassNode` while the owner came from the file-owner
aware `cachedFindEnclosingClassInfo`, so a Zig file-struct's top-level
fn produced `Method::Page.get` without the `#<arity>` suffix. It now
uses `findEnclosingClassNodeOrFileOwner`, the definition-phase lookup.
Consistency fix only: `ParseWorkerResult.calls` / `.assignments` (the
sole consumers of this id) are merged but not read since #942 — CALLS
edges come from the scope pipeline, whose ids were already right — so
no observable graph change and no test.
Not re-fixed:
- `test/helpers/literal-collectors.ts` `DIR_LANG` has no `zig` entry
(raised for the seventh time): the entry exists (`zig:
SupportedLanguages.Zig`, added by the second-pass commit), so
`languages/zig/**` literals are already validated against the Zig
grammar alone; documented in the PR body since the fifth pass.
* fix(zig): keyword-gate the constructor type-binding rules
The three `@type-binding.constructor` rules (`const p = T{…}`, `mod.T{…}`,
`List(u8){…}`) matched any `variable_declaration` with an identifier and a
`struct_initializer`, keyword or not — and tree-sitter-zig 1.1.2 parses a
re-assignment `p = T{…};` (and `_ = T{…};`) as the same node type. So an
assignment minted a constructor binding for `p` in its own block, and one
for `_`. Zig's static typing makes the extra binding redundant (`p`
already carries its type from its declaration: annotation, constructor or
inferred value), so it cost little, but it declared nothing and stood out
against every other binding rule (`@declaration.variable`, the import
rules, the call-return rules), which are keyword-gated for exactly this
shape. Split each rule into `"const" .` / `"var" .` variants, like the
call-return rules.
Regression test in `zig-extractors.test.ts`: `p = T{…}`, `q = mod.T{…}`,
`l = List(u8){}` and `_ = T{…}` after their declarations yield only the
three declaration bindings (fails on the previous query). The zig,
callable-value-flow, grammar-literal and tree-sitter-languages suites are
unchanged.
Raised twice by gitnexus-check (passes on 2026-08-18 12:42 and 12:56).
* fix(zig): re-baseline the callable-flow capture fingerprints, keep `await f<T>(x)` a direct callee
The `benchmarks (GITNEXUS_BENCH)` CI job gates two capture fingerprints
that this branch's shared callable-flow change (3e62b99a) moved without
re-baselining: `bench/python-scope/baseline-fingerprint.txt` and four
languages in `bench/scope-capture/baselines.json` (csharp, cpp,
typescript, kotlin). Both `--check` runs pass on origin/main and failed
on this branch; every other language matched its baseline on the same
run.
Drift, verified by dumping the canonical matches on both trees:
- csharp / kotlin / python: exactly the intended change — a MEMBER call
(`string.Join(x)`, `.forEach { }`, `' '.join(x)`, `.ljust(w)`) no
longer carries `direct-callee-name`; the argument fact is unchanged.
- cpp: `choice.select(1)` (cpp-deleted-overload) drops an INDIRECT
invoke + its synthetic `@reference.call.free` that were gated only by
the same-named free `select` binding; the site is a genuine method
call already captured as `@reference.call.member`. capture_groups_fp
4605 -> 4601.
- typescript: `await svc.verify<T>(x)` (member) and `initializer()(cb)`
(call-of-call) drop the name as intended. But `await verifyToken<T>(x)`
— a DIRECT call — lost it too, because tree-sitter-typescript parses
`await f<T>(x)` as `call_expression(function: await_expression(f),
type_arguments, …)` and the new direct-designator gate saw an
await_expression, not `f`. `wrappedExpression` now unwraps
`await_expression` (no named field, so the field-based unwrap missed
it), restoring parity with main for the direct spelling while the
member spelling stays nameless. Regression test added; it fails
without the unwrap on both assertions.
Gates run locally: scope-capture --check (15 languages), python-scope
--check, import-target --check, tsc, eslint, prettier, the callable-flow
/ golden / tripwire / resolver test files (33 files), full suite with
coverage (82.9/71.5/89.1/86.4 vs 26/23/28/27 thresholds).
* test(zig): fail CI when the optional Zig grammar is absent
`@tree-sitter-grammars/tree-sitter-zig` is an optionalDependency, so every
Zig suite gates on `isLanguageAvailable(Zig)` and the ABI load-smoke accepts
a clean load failure for an optional grammar. Both are the right contract for
a platform with no prebuild, and together they leave a hole: if the grammar
never installed on any CI runner, this PR would merge with all eight Zig
resolver suites plus the structure-phase suite reported green-by-skip, having
never executed the native Zig parser once.
Close it with the `GITNEXUS_REQUIRE_FTS` idiom already used for the FTS
suites. `GITNEXUS_REQUIRE_ZIG=1` declares "this runner has a prebuild, the
grammar MUST be here", and a missing grammar becomes a failure instead of a
skip. tree-sitter-zig@1.1.2 publishes prebuilds for {darwin,linux,win32}-
{x64,arm64}, so the flag is set on two required jobs that all run on covered
platforms: the sharded ubuntu `tests` job and the three-OS `abi-assert` job.
- test/helpers/optional-grammar.ts: the registry mapping a language to its
require-variable, plus `describeGrammarPresence`, a presence assertion that
FAILS when required-but-absent. Deliberately a separate test rather than
flipping the suites from skip to fail: a skipped suite reports success, so
only a failing test can turn "Zig never ran" into a red job.
- parser-loader-abi.test.ts: the optional exemption is revoked for a language
the environment declares required, so an ABI-broken Zig binding fails the
smoke instead of passing as a clean absence.
- optional-grammar-gate.test.ts: pins the two ways the gate could silently
never fire — reading a variable name CI does not set, or accepting a value
CI does not write.
Nothing changes for a run that leaves the variable unset: local runs and any
future prebuild-less platform still skip. Verified both directions --
`GITNEXUS_REQUIRE_ZIG=1` alone: 149 passed, 0 skipped; with
`GITNEXUS_SKIP_OPTIONAL_GRAMMARS=1` forcing the grammar away it fails 2 tests
with an actionable message; with the skip flag but no require flag it is
green-by-skip exactly as before.
Addresses the test-only blocker in the gitnexus-check review of #1432.
* fix(zig): type the optional-grammar gate by grammar key, not language
The gitnexus-check finding on parser-loader-abi.test.ts:155 is right, and
none of the gates caught it: `tsconfig.json` includes only `src/**/*`, so
neither `tsc --noEmit` nor CI typechecks the test tree, and vitest strips
types without checking them. Confirmed with a scoped tsc run over the file:
`error TS2345: Argument of type 'string' is not assignable to parameter of
type 'SupportedLanguages'`.
Not fixed with the proposed `key as SupportedLanguages` cast, which would
assert something false: `listGrammarSources()` yields one row per SOURCES
entry, including variants like `typescript:tsx` that are not enum members.
`isOptionalGrammarRequired` now takes the grammar KEY it is really given,
and the registry keeps a `satisfies Partial<Record<SupportedLanguages,
string>>` so every key we write is still pinned to a real language.
Two new cases cover the failure mode the type error was pointing at — a
registry key that can never match what the ABI smoke passes, leaving the
gate configured-looking and permanently inert: every OPTIONAL_GRAMMAR_ENV
key must be a key `listGrammarSources()` yields and must be marked optional
there, and an unregistered variant (`typescript:tsx`) must not be required
even with the variable set.
Same blind spot, two more latent errors in files this PR adds, both fixed:
`Parser.Language` is not an exported member (use the `setLanguage` parameter
type, as parser-loader-abi.test.ts already does), and the `ParsedImport`
filter did not narrow the union, so `localName` was read through a `!` on an
arm that has no such property — now a type predicate. The one remaining
error under the same probe, in `resolvers/callable-value-flow.test.ts:319`,
predates this branch (authored 2026-07-17, on main) and is left alone.
structural-pair-coverage's optional-grammar case switches from
`it.concurrent.each` to `it.concurrent.for`: only `for` passes the test
context as a second argument (`each`'s callback is `(...args: T[])`), and
that context carries the dynamic `skip()` the per-language gate calls.
Behaviour is unchanged — grammar present: 10 passed; grammar forced away:
9 passed, 1 skipped.
Whole test tree typechecking is a separate, much larger job: the same probe
over `test/**` minus fixtures reports 734 pre-existing errors across the
repo. Out of scope here.
* fix(zig): address tenth gitnexus-check review pass
- `normalizeZigDepPath`: normalize backslashes BEFORE the absolute-path
check. A UNC dep (`\\server\share\dep`) used to slip past the check and
normalize to the repo-relative `server/share/dep`; root-relative `\dep`
had the same hole. Both now return null. Regression case added to the
absolute-spellings test with the files those misreadings would resolve.
- `bindPayloads`: a pointer capture `for (pages) |*p|` now records `*Page`
(declaredSpelling) instead of `Page` — the `*` is an anonymous payload
child before the identifier. Method dispatch is unchanged (`rawName`
strips the sigil), but a deref projection `const q = p.*;` now sees the
pointer layer. New fixture fn `viaPtrCaptureDeref` + assertion; fails on
the previous code (verified by stashing the src fix).
- `optional-grammar-gate.test.ts`: renamed the `typescript:tsx` case — the
key IS a registry row; what makes it inert is the missing gate entry. Now
also asserts a key no registry yields.
- `structural-pair-coverage.test.ts`: header updated — ten tables (not
eleven) are absent from every rule's target side; `Union` left the set
when Zig made it linkable.
- `language-classification.ts`: doc comment now names zig in the
experimental set (added after Ring 1).
Not re-fixed (invalid findings):
- "owner-hook contract wired to an undeclared variable": stale-diff read —
`findEnclosingClassInfo` declares `resolveFileTypeOwner` /
`resolveContainerTypeOwner` as optional parameters (ast-helpers.ts:905,
917) and parse-worker threads them at every call site; tsc compiles clean.
- "optional Zig grammar added unconditionally to the parsing fixture
suite": the cited block only `fs.readFile`s the committed fixture file to
assert it is non-empty — no parser or grammar load is involved.
* fix(scope-resolution): mark construction-site CALLS edges in reason (opt-in), enable for Zig
PR #1432 human review, item 2: a Zig struct literal `T{ .f = x }` (no
parens) is modelled as a CALLS edge to the type — the Rust `T { .. }` /
Go `T{}` shape — and nothing on the edge told it apart from an invocation
(`get_next_spawn → SpawnRequest` from seven `return SpawnRequest{ … }`).
`ScopeResolver.markConstructionSites` (default off): when set, the edge
emitted for a `callForm === 'constructor'` site gets ` (constructor)`
appended to its reason, in both emit paths — `local-call (constructor)` /
`import-resolved (constructor)` in the free-call fallback and
`scope-resolution: call (constructor)` in the reference bridge. The Zig
resolver opts in. `Reference` gains an optional `callForm`, copied from
the site by `buildReference`, so the bridge can see the form.
Why `reason` and not a property or edge type: relationships carry no
arbitrary properties, a new column changes the relation DDL and moves
SCHEMA_FINGERPRINT, and `reason` is the channel the IMPLEMENTS `-pointer`
receiver form already uses. Why opt-in: the unsuffixed strings are a
pinned contract asserted verbatim by the other language suites
(php/cpp constructor calls expect exactly `import-resolved`); every
non-Zig edge stays byte-identical.
Tests: `references-to-edges-call-form.test.ts` pins both vocabularies
and the default-off behaviour; `zig.test.ts` asserts
`Reflect.string → Accessor` / `Reflect.url → Accessor` carry
`local-call (constructor)` next to a plain invocation, and that every
marked edge targets a Struct.
* feat(zig): track qualified struct literals (`mod.T{…}`) as construction sites
PR #1432 re-test (issue comment on 97571d23): 163 qualified literals
`mod.Type{ … }` in a real project produced no CALLS edge at all, so only
same-file and imported-name literals were tracked as construction sites.
One query rule captures `(struct_initializer (field_expression object
member))` as `@reference.call.constructor` WITH the receiver. Captured as a
free constructor instead, the site resolves by its simple tail and a
workspace-unique `Thing` answers for `c.Thing{}` whichever module the
source named (measured: c.zig defines no `Thing`, the edge went to a.zig's).
With the receiver the site takes the receiver-bound namespace case — the
path `mod.fn()` takes — which resolves inside the module the receiver is
bound to: `a.Thing{}` / `b.Thing{}` bind their own files, `c.Thing{}` binds
nothing, `std.Thread.Mutex{}` binds nothing next to a local `Mutex`.
That case's edge now goes through `constructionSiteReason` too, so the
opt-in marker (`import-resolved (constructor)` / `global (constructor)`)
reaches it; `markConstructionSites` joins `ReceiverBoundProviderSubset`.
Byte-identical for every provider that does not set the flag.
Also answers the twelfth gitnexus-check pass: the `bodyNodeSet.size === 0`
guard on the extractor factories' no-wrapper branch is deliberate (a config
with wrappers whose node lacks one is a bodiless declaration); the two
comments now say so instead of reading as a universal last resort. Go's
method config, the only other empty-`bodyNodeTypes` config, never reaches
the branch (its `extract()` gates on method/function nodes the class-node
caller never passes).
Tests: new `zig-qualified-literal` fixture (same-named `Thing` in two
modules, a module without it, an external `std` qualifier next to a local
and an imported `Mutex`); `zig-basic` pins `pioneer.Pioneer{…}` and the
union `pioneer.Tag{…}` as marked construction sites.
* feat(zig): resolve hub re-exports, enum-variant receivers and type-named receivers (real-project audit)
Audit of three real Zig projects indexed with this branch (tigerbeetle 246
files, mach 132, ghostty 788): method reachability was 63 % / 35 % / 55 %,
and three shapes accounted for most of the misses.
1. Hub modules. Zig projects publish types through a file made only of
re-exports (`pub const Terminal = @import("Terminal.zig");`, `pub const
PRNG = @import("prng.zig");`, `pub const Thing = @import("thing.zig")
.Thing;`). Such a file owns NO local binding, and `findExportedDef` reads
local bindings only — so `terminal.Terminal.init()`, `t: stdx.Thing`,
`var p = stdx.PRNG.from_seed()` and `h: stdx.BoundedArrayType(u8, 4)`
all resolved to nothing. Measured before → after: CALLS into ghostty's
`src/terminal/` from outside it 46 → 253 (150 `terminal.Terminal.` sites
alone); into tigerbeetle's `stdx` hub from outside it 837 → 1500 (136
static calls, 289 annotations). Method reachability: tigerbeetle
2249 → 2272 of 3544, ghostty 2766 → 2865 of 5016, mach 1047 → 1051 of
2967 (mach's hub publishes generic instantiations, `pub const Quat =
q.Quat(f32)`, a shape this commit does not cover).
`findExportedDefIncludingImportedNames` reads the finalized channel
(origin import / namespace / reexport, def already resolved to the
declaring file), refusing a name bound to two distinct defs. Opt-in per
provider (`namespaceExportsIncludeImportedNames`): a module's imports are
not its exports in most languages; Zig opts in because a hub member a
consumer can name is public by construction. Used by receiver-bound Case
1, Case 3, the compound resolver's namespace branch, and a new Case 2
route that resolves a namespace-qualified class receiver (`stdx.PRNG`)
through the same lookup.
2. Enum variants as receivers. `Operation.create_accounts.event_max()`
(147 sites in tigerbeetle): a variant has no written type, but it has
one — the enum itself. `emitZigScopeCaptures` now emits a field type
binding per enum variant, so the field walk that already handles
`self.session.name()` types `Op.create` as `Op`.
3. Receivers named after their type. `self` is a convention, not a rule:
tigerbeetle writes `replica: *Replica` (777 of 1127 methods), mach
`pool: *@This()` (764 of 833). Reading only `self` as the receiver
labelled all of them `isStatic: true`, counted the receiver in their
arity (`Counter.incr#1`) and sourced the scope binding as a plain
parameter. `zigReceiverParameter` is the single rule for both phases:
the FIRST parameter when named `self`, or typed as the enclosing
container (`@This()`, its binding name, a `const X = @This();` alias),
pointers / const / optionals stripped.
Fixtures `zig-hub` and `zig-receivers` pin each shape, including the
refusals: a private hub import does not leak, a foreign-typed first
parameter is not a receiver, a factory stays static.
* fix(zig): address thirteenth gitnexus-check review pass
- File-struct receivers named after the file stem were always static: the
method builder called `isStatic` / `extractReceiverType` /
`extractParameters` without the extractor context's `filePath`, so
`zigReceiverParameter` could not name a file-struct (`fn add(ledger:
*Ledger)` in `Ledger.zig`, no `Self` alias) and the fn came out static
with the receiver in its arity (`Ledger.add#2`) — an id the scope side,
which always has the path, never produces, so its CALLS edges went
nowhere. `MethodExtractionConfig` now passes `filePath` as an optional
trailing argument to those three hooks (same shape as
`extractOwnerName`); the Zig config threads it through, every other
config ignores it. Regression tests in `zig-extractors.test.ts` (unit)
and `resolvers/zig.test.ts` (new `Ledger.zig` in the `zig-receivers`
fixture: ids, `isStatic`, and the three CALLS edges); both fail on the
previous source.
- `LINKABLE_LABELS` comment: the remaining `CLASS_KINDS` entries include
`Namespace`.
Not re-fixed:
- "Ownerless-method assertion regex cannot match `.zig` graph IDs": the
`[^:]+` segment consumes the whole file path (dots included) up to the
second colon, and `[^.]+#\d+$` then matches only an owner-less name —
`Method:src/Sorter.zig:lessThan#3` → true, `…:Sorter.sortBoth$1.lessThan#3`
→ false, checked with node.
- "Public namespace imports are never marked as re-exports": the shared
`ParsedImport` namespace variant has no `reexportsName` field and
`contributesReexportEdge` excludes namespace drafts on `base.kind` by
contract; a `pub const X = @import("x.zig")` hub member is exposed
through `findExportedDefIncludingImportedNames` instead, which is what
the audit commit added for exactly that shape.
- "Private Zig namespace imports are treated as public hub exports": a
private import cannot be named through the hub in code that compiles,
and `findExportedDef` applies the same no-visibility rule to local
defs; the finalized binding channel carries no `pub` bit to check.
- "Range binding mutates finalized scopes" and "unconditionally adds an
optional Zig grammar to the fixture suite": refuted in the tenth and
eleventh pass notes of the PR body, unchanged since.
* fix(zig): close the adversarial review's ten findings (8.2–8.12)
PR #1432 review 5095267917 on 34c53473 retained eight P1 and two P2
findings; each is reproduced on the new `zig-chains` / `zig-buildmodules`
fixtures with the decoy that made the old answer wrong, and pinned by a
test named after its number.
- 8.2 per-build-module import tables (`parseZigBuildModules`): a source
resolves a bare name through its own module's `addImport` table (root
file, else deepest root directory), fails closed when same-directory
modules disagree, and follows `addImport("api", dep.module("core"))`
through the dep's `addModule`; repo-wide names and zon deps remain the
fallback.
- 8.3 module-level value receivers (`zigHostValueNames`) prepend the
implicit `self` like fn-locals, so `global_runner.run(cb)` joins `cb@1`.
- 8.4 deep member aliases (`@import("lib.zig").B.work`, `lib.B.work`)
keep the written owner: the module is bound as a namespace and the
alias's use sites are rewritten to `receiver . member`; only one-level
aliases are promoted to named imports.
- 8.5 container-hosted containers get owner-qualified identities
(`A.Item`, `B.Item`, `Outer.Inner`), minted by the bare-container rule,
while the scope keeps the lexical binding.
- 8.6 result-location `.init(…)` / `.{…}` under an annotation, a return
type or a field type emit the call / construction site with the
expected type as receiver.
- 8.7 Zig arm in bench/import-target (five dispatchers, config-free
fingerprint) + baselines row; `--check` passes.
- 8.9 fn-local `@import` bindings and their uses are keyed per callable
(`m$f_sib_a`), so sibling fns no longer share one namespace bucket.
- 8.10 `ScopeResolver.resolveNamespaceChains` (opt-in, Zig only): Case 1
/ Case 2 / Case 3 and the compound resolver walk a qualified receiver
segment by segment — republished modules, nested types, enum variants
through the module — refusing ambiguous hops. Off, every lookup keeps
its one-hop split; the 70 resolver suites are unchanged.
- 8.11 `@import("a.zig").Thing{}` binds the module as a namespace in type
position; `List(u8){}` / `lists.List(u8){}` get constructor sites.
- 8.12 a fieldless file whose top-level fn takes the file's own type
(`self: *@This()`, `self: *Self`) is a file-struct; two over-matching
ZIG_QUERIES rules are filtered by `shouldSkipDefinitionCapture`.
Also asserts the committed `opmod.Op.lookup.event_max()` call in zig-hub.
* fix(zig): address gitnexus-check findings on 215f70e3
- receiver-bound Case 3 wraps its reason in constructionSiteReason, like
Case 1 and the nested-type route of Case 2 (one vocabulary per provider)
- resolveZigImportInternal rejects drive-qualified absolute imports
(C:\foo.zig), the same test normalizeZigDepPath applies; unit case added
- the compound resolver's chain seed also tries the whole receiver as the
qualified class (opmod.Op), as a bare class-name head already does
- markConstructionSites contract text names the receiver-bound routes
The return_type field claim is refuted: tree-sitter-zig exposes a fn's
return type as the type field (checked on the grammar).
* fix(zig): a build-module alias bound to an unindexed root fails closed
resolveThroughBuildModules returned undefined when the containing module
bound the alias to a file that is not indexed, which let the repo-wide
addModule map answer under the same name (gitnexus-check on 5299c552).
The module's table is the authority for its aliases: bound-but-unindexed
is null, only an unbound name falls through. Unit case with a same-named
repo-wide decoy, plus the outside-module file that still reaches it.
* fix(zig): an unindexed root module fails closed, never a same-named zon dep
The root build.zig's addModule declaration is authoritative for a bare
name when it binds it; a root that is not indexed used to fall through
to a build.zig.zon path dep of the same name — a different declaration
answering under the name (gitnexus-check on fe24b37f). Same rule as the
build-module tables. Unit case added.

* bench(receiver-resolution): rebaseline for the Zig lang-resolution fixtures
The receiver-resolution gate (#2856/#2899) landed on main after this branch
forked and counts call drops over test/fixtures/lang-resolution, which this
branch extends with the zig-* fixture projects. Regenerated with
`measure.mjs --update-baseline`: callDrops 102 -> 113, all 11 new drops in
.zig files, shape `no-chain`.
Every new drop is a call whose callee has no node in the corpus, not a
resolver regression: `std.Build.Module.addImport` in the three build.zig
fixtures (7, classified in-program), `std.sort.pdq` in Sorter.zig (2,
unknown), `std.Thread.Mutex{}` / `std.mem.Allocator{}` literals in
zig-qualified-literal (2, unknown, the fixture asserts std stays external),
and one `.init()` decl literal on a generic instantiation
(`const u: Stack(u16) = .init()`, in-program). Shape arm unchanged.

The nervous system for agent context.
Indexes any codebase into a knowledge graph — every dependency, call chain, cluster, and execution flow — then exposes it through smart MCP tools so AI agents never miss code.
💬 Discord · 🌐 Web UI · 🏢 Enterprise (SaaS & self-hosted)
https://github.com/user-attachments/assets/172685ba-8e54-4ea7-9ad1-e31a3398da72
Like DeepWiki, but deeper. DeepWiki helps you understand code. GitNexus lets you analyze it — a knowledge graph tracks every relationship, not just descriptions.
TL;DR: The CLI + MCP makes your AI agent reliable — it gives Cursor, Claude Code, Antigravity, Codex, and friends a deep architectural view of your codebase so they stop missing dependencies, breaking call chains, and shipping blind edits. Even smaller models get full architectural clarity. The Web UI is a quick way to chat with any repo in the browser.
Quick Start
# 1. Index your repo (run from repo root)
npx gitnexus analyze
# 2. Connect your editors (one-time, auto-detects Claude Code, Cursor, Codex, …)
npx gitnexus setup
That's it. analyze indexes the codebase, installs agent skills, registers Claude Code hooks, and creates AGENTS.md / CLAUDE.md context files — all in one command. setup writes the MCP config so your AI agent can use the graph.
Install problems? npm 11 crash · slow cold install · no C++ toolchain
On npm 11.x?
npxcan crash during install withCannot destructure property 'package' of 'node.target'(an npm/arborist bug, before GitNexus runs). Use pnpm instead — it builds the native deps explicitly:pnpm --allow-build=@ladybugdb/core --allow-build=gitnexus --allow-build=tree-sitter dlx gitnexus@latest analyzeOr install globally (
npm install -g gitnexus@latest) and rungitnexus analyze. See #1939.
Fastest MCP startup: install globally (
npm i -g gitnexus) before runninggitnexus setup— this writes an absolute-path MCP config that bypassesnpxentirely. On a cold cache, annpx-based MCP install can exceed Claude Code'sMCP_TIMEOUTdefault (~30s).
No C++ toolchain? Set
GITNEXUS_SKIP_OPTIONAL_GRAMMARS=1beforenpm install -g gitnexusto skip the vendored grammar materialize/build fortree-sitter-dart,tree-sitter-proto,tree-sitter-swift, andtree-sitter-kotlin— those four languages won't be parsed, but install completes in seconds withoutpython3/make/g++. Strict=1only — any other value falls through to the rebuild.
Behind an HTTP proxy / regional firewall?
onnxruntime-node's postinstall downloads optional CUDA binaries fromapi.nuget.organd ignoresHTTP_PROXY/HTTPS_PROXY(#2370). The embedding stack is an optional dependency, so a failed download no longer breaks the install — and it self-heals: the firstgitnexus analyze --embeddings(orgitnexus embeddings install) fetches the stack through your npm registry config (mirrors/proxies apply, no NuGet) into~/.gitnexus/embedding-runtime(override withGITNEXUS_EMBEDDING_RUNTIME_DIR). The on-demand prefix needs Node withmodule.registerHooks(≥ 22.15 on 22.x, ≥ 23.5 on 23.x); on older Node, keep the stack in the install itself withONNXRUNTIME_NODE_INSTALL=skip npm install -g gitnexus(works on every supported Node).
About
tree-sitter-kotlin: like Dart/Proto/Swift, Kotlin is a vendored grammar (undergitnexus/vendor/tree-sitter-kotlin). Upstream ships source only (no prebuilt binaries), so GitNexus cross-builds the platform prebuilds itself (via thebuild-tree-sitter-prebuildsGitHub Actions workflow) and vendors them — the same uniform pipeline used for Dart, Proto, and Swift.node-gyp-buildselects the right.nodeat require time, so no C/C++ toolchain is needed. If no prebuild matches your platform-arch, only Kotlin (.kt/.kts) parsing is unavailable; the rest ofgitnexusis unaffected.
Deploy to Render
Deploy GitNexus in one click:
The Blueprint creates two services. gitnexus-server runs gitnexus serve as a private service: no public URL, reachable only over Render's private network, with a persistent disk for indexes and cloned repos. gitnexus-web is the public one. It serves the UI and reverse-proxies /api/* to the server, so the browser talks to a single origin.
At the Blueprint's defaults this runs about $35/month: $25 for the server's standard instance, $7 for the web service's starter instance, and $2.50 for the 10 GB disk. See Render's pricing for other plans.
The deploy generates an access token, and the UI asks for it on first use:
- Open the
gitnexus-webservice in your Render dashboard. - Copy
GITNEXUS_SERVE_AUTH_TOKENfrom its Environment tab. - Load the site and paste the token into the prompt (or the settings panel).
Every /api/* request carries that token as a header, and the proxy answers 401 without it. The browser keeps it in sessionStorage, so a new tab asks again. To rotate it, edit the environment variable and redeploy.
The proxy strips Origin before forwarding, so the server's CSRF guard does nothing for proxied traffic; it passes Origin-less requests through by design. The token is the only control on this deploy, not a second layer behind the guard. Anyone holding it can read every indexed repo. See SECURITY.md.
Indexing is memory-bound. If gitnexus-server runs out of memory on a large repo, raise its plan, which sets available RAM: standard is 2 GB, pro is 4 GB. Raise sizeGB only if the disk fills with clones and indexes.
Two Ways to Use GitNexus
| CLI + MCP (recommended) | Web UI | |
|---|---|---|
| What | Index repos locally, connect AI agents via MCP | Visual graph explorer + AI chat in browser |
| For | Daily development with Cursor, Claude Code, Antigravity, Codex, Windsurf, OpenCode | Quick exploration, demos, one-off analysis |
| Scale | Full repos, any size | Limited by browser memory (~5k files), or unlimited via backend mode |
| Install | npm install -g gitnexus |
No install — gitnexus.vercel.app |
| Storage | LadybugDB native (fast, persistent) | LadybugDB WASM (in-memory, per session) |
| Parsing | Tree-sitter native bindings | Tree-sitter WASM |
| Privacy | Everything local, no network | Everything in-browser, no server |
Bridge mode:
gitnexus serveconnects the two — the web UI auto-detects the local server and can browse all your CLI-indexed repos without re-uploading or re-indexing.
Why a Knowledge Graph?
Tools like Cursor, Claude Code, Codex, Cline, Roo Code, and Windsurf are powerful — but they don't truly know your codebase structure. So this happens:
- AI edits
UserService.validate() - Doesn't know 47 functions depend on its return type
- Breaking changes ship
Traditional Graph RAG gives the LLM raw graph edges and hopes it explores enough. GitNexus precomputes structure at index time — clustering, tracing, scoring — so tools return complete context in one call:
flowchart TB
subgraph Traditional["Traditional Graph RAG"]
direction TB
U1["User: What depends on UserService?"]
U1 --> LLM1["LLM receives raw graph"]
LLM1 --> Q1["Query 1: Find callers"]
Q1 --> Q2["Query 2: What files?"]

end
Core innovation: Precomputed Relational Intelligence
- Reliability — the LLM can't miss context; it's already in the tool response
- Token efficiency — no 10-query chains to understand one function
- Model democratization — smaller LLMs work because the tools do the heavy lifting

Repo-specific skills — run gitnexus analyze --skills and GitNexus detects the functional areas of your codebase (via Leiden community detection) and generates each one as a direct project skill under .claude/skills/gitnexus-area-<name>/. Each skill describes a module's key files, entry points, execution flows, and cross-area connections, and is regenerated on each --skills run to stay current.
When a repo contains an .agents/ directory, the standard and generated skills are also mirrored to .agents/skills/ (e.g. .agents/skills/gitnexus-cli/, .agents/skills/gitnexus-area-<name>/) so agents that read repo-local .agents/skills/ (like Codex) stay in sync.
Editor Setup
gitnexus setup auto-detects your editors and writes the correct global MCP config. Run it once. To configure only selected integrations, pass --coding-agent/-c with a comma-separated list, e.g. gitnexus setup -c cursor,codex.
| Editor | MCP | Skills | Hooks (auto-augment) | Support |
|---|---|---|---|---|
| Claude Code | Yes | Yes | Yes (PreToolUse + PostToolUse) | Full |
| Cursor | Yes | Yes | Yes (postToolUse, manual install) | Full |
| Antigravity (Google) | Yes | Yes | Yes (AfterTool, Gemini CLI hooks schema)¹ | Full |
| Codex | Yes | Yes | Yes (PreToolUse + PostToolUse, Codex hooks) | Full |
| OpenCode | Yes | Yes | — | MCP + Skills |
| CodeBuddy (Tencent) | Yes | Yes | — | MCP + Skills |
| Qoder (Alibaba) | Yes | Yes | — | MCP + Skills |
| Windsurf | Yes | — | — | MCP |
Claude Code and Codex get the deepest integration: MCP tools + agent skills + PreToolUse hooks that enrich searches with graph context + PostToolUse hooks that detect a stale index after commits and prompt the agent to reindex.
¹ Antigravity hooks follow the Gemini CLI hooks reference (Antigravity 2.0 is the documented successor to Gemini CLI). Augmentation runs in
AfterToolbecauseBeforeToolhas no context-injection channel in the Gemini contract — the agent sees graph context appended to the tool result viahookSpecificOutput.additionalContext. Stale-index hints land in the same channel after a successfulgit commit/merge/rebase/cherry-pick/pull. The schema may evolve if Antigravity-specific hook docs diverge from Gemini CLI's; the implementation will track those changes.
Manual MCP configuration (if you prefer not to run gitnexus setup)
Claude Code (full support — MCP + skills + hooks):
# macOS / Linux
claude mcp add gitnexus -- npx -y gitnexus@latest mcp
# Windows
claude mcp add gitnexus -- cmd /c npx -y gitnexus@latest mcp
Codex (full support — MCP + skills + hooks):
codex mcp add gitnexus -- npx -y gitnexus@latest mcp
Or via ~/.codex/config.toml (system scope) / .codex/config.toml (project scope):
[mcp_servers.gitnexus]
command = "npx"
args = ["-y", "gitnexus@latest", "mcp"]
Codex hooks (PreToolUse graph enrichment + PostToolUse stale-index detection in ~/.codex/hooks.json, same schema as Claude Code) need the bundled adapter script, so they are installed by gitnexus setup -c codex rather than manually.
Alternatively, install everything as a Codex plugin (MCP + skills + hooks in one step):
codex plugin marketplace add abhigyanpatwari/GitNexus
# then inside Codex: /plugins → install "GitNexus"
Codex notes: SessionStart is intentionally not registered — Codex reads AGENTS.md natively, which already carries the GitNexus context block. Newly installed hooks need a one-time approval in Codex via
/hooksbefore they run. Pick one install route (gitnexus setup -c codexor the plugin): plugin hooks load alongside~/.codex/hooks.json, so installing both can fire duplicate hooks per tool call.
Cursor (~/.cursor/mcp.json — global, works for all projects):
{
"mcpServers": {
"gitnexus": {
"command": "npx",
"args": ["-y", "gitnexus@latest", "mcp"]
}
}
}
Antigravity (Google) — ~/.gemini/antigravity/mcp_config.json:
{
"mcpServers": {
"gitnexus": {
"command": "npx",
"args": ["-y", "gitnexus@latest", "mcp"]
}
}
}
gitnexus setupalso merges anAfterToolentry into~/.gemini/settings.json(under the canonical Gemini CLI hooks schema) and installs skills to~/.gemini/antigravity/skills/. Existing user hooks are preserved. The hook adapter's path is rewritten at install time, so rungitnexus setuprather than hand-editing.
OpenCode (~/.config/opencode/config.json):
{
"mcp": {
"gitnexus": {
"type": "local",
"command": ["gitnexus", "mcp"]
}
}
}
CodeBuddy (Tencent) — priority chain, edit the first non-empty file that exists: ~/.codebuddy/.mcp.json (recommended) → ~/.codebuddy/mcp.json (deprecated) → ~/.codebuddy.json (legacy). CodeBuddy reads only the first existing file, so adding servers to a higher-priority file than the one currently in use would hide the servers below it. Create ~/.codebuddy/.mcp.json only if none exist:
{
"mcpServers": {
"gitnexus": {
"command": "npx",
"args": ["-y", "gitnexus@latest", "mcp"]
}
}
}
Qoder (Alibaba) — ~/.qoder.json:
{
"mcpServers": {
"gitnexus": {
"command": "npx",
"args": ["-y", "gitnexus@latest", "mcp"]
}
}
}
MCP read-only mode
Set GITNEXUS_MCP_READ_ONLY=1 before starting the MCP server to expose only the proven single-repository read surface. Raw cypher, rename and group tools, group routing, and group resources are omitted from discovery and rejected before backend dispatch. Tool descriptions and generated setup/context resources are scrubbed so they do not recommend unavailable routes.
The default is unchanged when the variable is unset or 0. Any other value fails server startup rather than silently weakening the policy.
MCP repository policy
Set GITNEXUS_MCP_ALLOWED_REPOS to a comma-separated list of canonical registry names or absolute indexed paths. Entries are trimmed, resolved against the registry, and deduplicated at startup. When exactly one repository is allowed it becomes the implicit default; when several are allowed, callers must select one unless GITNEXUS_MCP_DEFAULT_REPO is also set.
The default repository must resolve to an allowed repository. Invalid, ambiguous, blank, or mismatched configuration fails startup before stdio or HTTP begins serving. The allowlist applies to tools, aliases, discovery, resources, templates, implicit resolution, and embedded HTTP; hidden repository details are not included in selection errors. Setting only GITNEXUS_MCP_DEFAULT_REPO chooses a default without restricting explicit repository selections. An allowed repository whose name is duplicated in the registry must be configured by path, and its context resource is only served for the unique name form.
MCP response budgets
The query, context, and impact tools accept an optional positive-integer maxTokens argument. It bounds the complete formatted MCP response, including hints and error text, using a deterministic four-UTF-8-bytes-per-token estimate. When truncation is required, the response ends with … and remains valid UTF-8.
Set GITNEXUS_MCP_DEFAULT_MAX_TOKENS to apply the same guardrail when callers do not send maxTokens. An explicit tool argument takes precedence. Leaving both unset preserves the existing response byte-for-byte; this is a transport guardrail, not semantic pagination or an exact model-specific tokenizer limit.
CLI Reference
Everyday commands:
gitnexus setup # Configure MCP for detected editors (one-time; -c to select)
gitnexus analyze [path] # Index a repository (or update a stale index)
gitnexus analyze [path] --watch # Watch local files and serialize incremental refreshes
gitnexus mcp # Start MCP server (stdio) — serves all indexed repos
gitnexus serve # Start local HTTP server (multi-repo) for web UI connection
gitnexus eval-server # Start lightweight evaluation HTTP tools (loopback by default)
gitnexus list # List all indexed repositories
gitnexus status # Show index status for current repo
gitnexus clean # Delete index for current repo
gitnexus wiki [path] # Generate repository wiki from knowledge graph
gitnexus uninstall # Preview removal of GitNexus MCP/skills/hooks (--force to apply)
You can also query the graph directly from the terminal — gitnexus query, context, impact, trace, cypher, detect-changes, and check mirror the MCP tools of the same names, and gitnexus doctor prints runtime platform capabilities.
gitnexus analyze --watch requires a Git repository. It runs one initial
analysis, then debounces scanner-admitted working-tree changes for 300 ms by
default and applies serialized incremental refreshes. Events arriving during a
refresh remain queued, and retryable failures retain the same batch with bounded
backoff. Invalid .gitnexusrc or ignore-file reloads pause ordinary refreshes
until the control file is fixed. Stop the watcher with Ctrl+C.
Watch mode accepts --debounce, --workers, --worker-timeout,
--max-file-size, --branch, --pdg, --name, --allow-duplicate-name, and
--verbose. Explicit one-shot options such as --force, --repair-fts,
embedding flags, --skills, --self-commit, --index-only, and --skip-git
are rejected. Unsupported defaults from .gitnexusrc are ignored with a
warning rather than making an otherwise valid repository unwatchable.
POSIX requests clone-first copy-and-swap publication when the live index has no
orphan sidecars. Windows and sidecar fallback runs update in place: failures
known to occur before writes are retried, while a failure that may have mutated
the live index stops the watcher. Watch mode does not pull remotes. Running MCP
and serve processes reopen a newly published index automatically; MCP observes
the replacement on its next tool call, typically within five seconds, so no
restart is required.
Authenticated eval-server binding
gitnexus eval-server binds to 127.0.0.1 by default. Loopback bindings do not require authentication. Any non-loopback bind, including 0.0.0.0, a LAN address, or a hostname that resolves to a LAN IPv4 address, requires GITNEXUS_AUTH_TOKEN. Every endpoint then requires an exact Authorization: Bearer <token> header.
GITNEXUS_AUTH_TOKEN='replace-me' gitnexus eval-server --host 0.0.0.0
The token may be set in the shell, .env.local, or .env in the working directory. Precedence is shell > .env.local > .env. Only GITNEXUS_AUTH_TOKEN is read from those files; their other values are not added to the process environment. Keep token files uncommitted.
All analyze flags
gitnexus analyze --force # Full rebuild: re-parse + graph rebuild + FTS rebuild
gitnexus analyze --repair-fts # Fast path: rebuild/verify only FTS indexes on existing index data
gitnexus analyze --skills # Generate repo-specific skill files from detected communities
gitnexus analyze --skip-embeddings # Skip embedding generation (faster)
gitnexus analyze --embeddings [limit] # Enable embedding generation (slower, better search)
gitnexus analyze --skip-agents-md # Preserve custom AGENTS.md/CLAUDE.md gitnexus section edits
gitnexus analyze --skip-skills # Skip installing standard skill files under .claude/skills/ and .agents/skills/
gitnexus analyze --skip-git # Index folders that are not Git repositories
gitnexus analyze --default-branch develop # Branch used in the generated regression-compare example (base_ref)
gitnexus analyze --verbose # Log skipped files when parsers are unavailable
gitnexus analyze --worker-timeout 60 # Increase worker idle timeout for slow parses
gitnexus analyze --workers <n> # Parse worker pool size (>=1; default: cores-1, capped at 16,
# auto-sized to the repo). 0 is rejected — there is no sequential mode.
gitnexus analyze --spring-actuator ./actuator # Enrich with local Spring Boot Actuator JSON snapshots
gitnexus analyze --asyncapi-spec ./docs/asyncapi # Resolve broker addresses from AsyncAPI 3.x documents
gitnexus analyze --wal-checkpoint-threshold 67108864 # LadybugDB WAL auto-checkpoint threshold in bytes
# (default 67108864 = 64 MiB; -1 keeps Ladybug stock ~16 MiB)
--spring-actuator is explicitly opt-in and accepts either a JSON bundle keyed by mappings, beans, conditions, configprops, and/or env, or a directory containing endpoint-named JSON files. It confirms matching static nodes and adds conservative runtime-only routes, beans, and property keys. The configured input is excluded from source scanning; only normalized repository-relative exclusions are retained for future scans, never absolute paths. Env/configprops values, origins, condition messages, and source names are never persisted or printed. Because snapshots are external runtime state, an enabled run always rebuilds; the first later run without the option rebuilds once to remove runtime evidence. The same path can be set as springActuator in .gitnexusrc.
--asyncapi-spec is explicitly opt-in and accepts a directory of AsyncAPI documents or a single document; the path is resolved against the repository root, so a committed docs/asyncapi and an absolute cache written by something else both work. Each operations[] entry of an AsyncAPI 3.x document can contribute a Destination node keyed by broker and address, with action: send emitting PUBLISHES_TO and action: receive emitting CONSUMES_FROM, so a document and source code that name one address on one broker land on the same node. Edges start at the document, not at a callable — a document states that the service talks to an address, not which method does — and no address a document names is ever attached to an unresolved source site.
An operation must name a protocol, either through its own bindings or through the servers[].protocol of the servers its channel resolves to (a channel that lists no servers resolves to all of them); operations that name none are refused, as are operations whose two readings name different brokers, and channels that inherit a multi-protocol server set without choosing. HTTP and WebSocket documents are refused for destination minting: there the host rather than the address names the place, and an HTTP endpoint is already modelled as a Route. A parameterized address — a channel declaring parameters, or an address containing { — is refused rather than keyed: two services publishing {env}.orders share a pattern, not a queue. AsyncAPI 2.x is refused under its own counted reason and never mapped, because its publish/subscribe are inverted relative to 3.x send/receive and a naive mapping would reverse the async graph while leaving it connected. Every refusal is counted, and a configured path that yields nothing is reported rather than passed over in silence.
Like Actuator snapshots, documents are external to git freshness — replacing one moves no commit and dirties no file — so an enabled run always rebuilds, and the first later run without the option rebuilds once to remove document-derived evidence. There is no glob-based auto-discovery, and the option is unsupported with --watch.
If analyze reports a worker parse timeout on a large or unusual repository, it keeps running and falls back safely. To give slow worker jobs more time, use --worker-timeout 60 or set GITNEXUS_WORKER_SUB_BATCH_TIMEOUT_MS=60000. For very large files, GITNEXUS_WORKER_SUB_BATCH_MAX_BYTES controls the worker job byte budget.
Embeddings node limit — gitnexus analyze --embeddings generates semantic search vectors with a default 50,000-node safety cap to protect memory on large repositories:
gitnexus analyze --embeddings # default 50,000 node safety cap
gitnexus analyze --embeddings 0 # disable the cap entirely
gitnexus analyze --embeddings 100000 # custom cap
If embeddings are skipped on a large repository, the indexed graph likely exceeds the default cap — re-run with --embeddings 0 or a higher limit.
Keep remote repositories indexed with gitnexus auto-sync
gitnexus auto-sync clones or pulls configured repositories, analyzes new commits, and optionally syncs their group. It runs once immediately, then repeats on the configured interval. It runs in the foreground; use your process manager if it must survive a shell session. gitnexus watch is reserved and prints this split; it does not start auto-sync or local file watching.
# 1. Create the config once. It never overwrites an existing file.
gitnexus auto-sync init
# 2. Edit $GITNEXUS_HOME/watch_config.yml, then start it.
gitnexus auto-sync start # `gitnexus auto-sync` is equivalent
gitnexus auto-sync status
gitnexus auto-sync restart # Required after config changes
gitnexus auto-sync stop
gitnexus auto-sync reset # Clear failure state; leaves clones and indexes intact
GITNEXUS_HOME defaults to ~/.gitnexus. A minimal configuration:
sync_interval_minutes: 10
analyze_timeout: 5m
projects:
- local_path: /absolute/path/to/clones
branches: [main, master]
overwrite_local_changes: false
remote_urls:
- git@github.com:owner/repo.git
sync_interval_minutesmust be at least5;local_pathmust be an absolute path. Clones are stored below it ashost/namespace/repo.- Remote URLs must use SSH SCP form and are limited to GitHub, GitLab, or Gitee.
branchesare tried in order. The legacybranchfield is supported, but do not set both.- Analysis runs in an isolated worker;
analyze_timeoutdefaults to, and cannot exceed, half ofsync_interval_minutes. Timeout andauto-sync stoprequest safe cancellation; a worker in native work exits after reaching a JS-visible safe point. Until then, auto-sync reportscancellingorstoppingand retains ownership so another auto-sync cannot take over, for up to 5 seconds — after that the parent stops waiting and leaves the worker to exit on its own rather than killing it mid-write. This behavior is the same on macOS and Windows.overwrite_local_changesdefaults tofalse, so a dirty local clone is skipped rather than overwritten; setting it totruealso deletes untracked files in the clone, while keeping ignored paths. - Add
group_nameonly after creating that group withgitnexus group create <name>. Partial clone output is isolated and removed after 14 days.
See the full auto-sync configuration and runtime reference for concurrency, timeouts, failure thresholds, and runtime files.
Repository groups (multi-repo / monorepo service tracking)
gitnexus group create <name> # Create a repository group
gitnexus group add <group> <groupPath> <registryName> # Add a repo. <groupPath> is a hierarchy path
# (e.g. hr/hiring/backend); <registryName> is the
# repo's name from the registry (see `gitnexus list`)
gitnexus group remove <group> <groupPath> # Remove a repo by its hierarchy path
gitnexus group list [name] # List groups, or show one group's config
gitnexus group sync <name> # Extract contracts and match across repos/services
gitnexus group contracts <name> # Inspect extracted contracts and cross-links
gitnexus group query <name> <q> # Search execution flows across all repos in a group
gitnexus group status <name> # Check staleness of repos in a group
gitnexus group impact <name> --target <symbol> --repo <groupPath> # Cross-repo blast radius
Project config (.gitnexusrc)
Commit a .gitnexusrc JSON file at the repo root to preconfigure recurring analyze options per project, instead of re-passing the same flags every run. It is read from the resolved repo root (not .gitnexus/, which is gitignored index storage). CLI flags always override .gitnexusrc.
{
// Default branch used in the generated regression-compare example (base_ref).
// Use this so a project on `develop`/`master` doesn't get "main" rewritten
// over its fix on every analyze. (Alias: "branch".)
"defaultBranch": "develop",
"skipContextFiles": true, // alias of skipAgentsMd: keep your own AGENTS.md/CLAUDE.md
"skipSkills": true, // don't install standard skill files under .claude/skills/ and .agents/skills/
"embeddings": true, // generate embeddings by default
"springActuator": "./actuator", // optional local runtime snapshot directory or bundle
"workerTimeout": 60,
}
A nested analyze block is also accepted (and overrides flat keys for the same option):
{ "analyze": { "defaultBranch": "develop", "skipSkills": true } }
Notes:
- The default branch is resolved as:
--default-branch>.gitnexusrcdefaultBranch/branch> auto-detectedorigin/HEAD>main. skipContextFiles/skipAiContextare aliases forskipAgentsMd— they skip theAGENTS.md/CLAUDE.mdblock only. They do not implyskipSkills.indexOnlyis the stronger option that skips all file injection.- Supported keys:
defaultBranch(branch),skipAgentsMd(skipContextFiles,skipAiContext),skipSkills,indexOnly,stats/noStats,embeddings,dropEmbeddings,name,allowDuplicateName,maxFileSize,workerTimeout,walCheckpointThreshold,workers,springActuator,embeddingThreads,embeddingBatchSize,embeddingSubBatchSize,embeddingDevice. - The file is JSON only. Unknown keys and invalid values fail fast with an actionable error before analysis starts.
Environment variables
Most analyze knobs are also CLI flags (--workers, --worker-timeout, --max-file-size, --verbose). Use the env-var form when you'd otherwise repeat the same flag every run, or when invoking GitNexus from a long-running host (MCP server, eval-server, CI shell) that already manages its own environment. CLI flags take precedence over env vars; env vars take precedence over built-in defaults.
| Variable | Default | Effect | Tune when… |
|---|---|---|---|
GITNEXUS_WORKER_POOL_SIZE |
cores - 1, capped at 16 |
Parse worker pool size (must be ≥ 1). Equivalent to --workers <n>. The worker pool is the sole parse path — there is no sequential parser, so 0 is rejected with an actionable error (the pool self-heals via quarantine + respawn). |
Constrained containers (cgroup CPU limits) or CI runners with explicit quotas. To narrow down a worker crash set 1 for a single-worker pool — not 0. |
GITNEXUS_PARSE_CHUNK_CONCURRENCY |
2 |
Number of chunks whose file contents may be read into memory in parallel while the pool dispatches the current chunk. Worker dispatch itself stays serial. | Repos large enough to chunk (multi-MB total source) where disk I/O is a measurable fraction of analyze wall-clock. |
GITNEXUS_VERBOSE |
unset | When 1, enables verbose ingestion logs (skipped-file warnings, per-chunk throughput, parse-cache stats). Equivalent to --verbose. |
Debugging an analyze that "completed" but seems to have missed files; tuning --workers / chunk concurrency against observable throughput. |
GITNEXUS_ANALYZER_IDENTITY_IN_PROCESS_GUARDS |
unset | When truthy (1/true/yes), forces in-process cache-guard validation once a batch has ≥128 requests. In-process mode also auto-selects when packageRoot/buildRoot fail W_OK with EACCES/EROFS. Otherwise those large batches use a Node subprocess probe. Batches under 128 always stay in-process. |
Trusted or read-only installs where two identity subprocess spawns per analyze dominate wall time; leave unset to keep the default isolation path on writable trees. |
GITNEXUS_RESOLVE_DEF_GRAPH_ID_MEMO |
on (unset) | Memoizes resolveDefGraphId per nodeLookup instance (WeakMap). Enabled by default. Set to 0/false/off/no to disable and recompute on every call (debug / bisect memo bugs). |
Suspecting stale graph-id resolution after a lookup rebuild, or comparing memo vs uncached cost on a large index. |
GITNEXUS_AUTH_TOKEN |
unset | Bearer token required when eval-server binds beyond loopback. May also be read from .env.local or .env; shell values take precedence. |
Exposing the evaluation HTTP tools to a container, VM, or LAN. |
GITNEXUS_MCP_AUTH_TOKEN |
unset | Bearer token for the dedicated gitnexus mcp --http server, for a directly reachable gitnexus serve /api/mcp route, and for the docker-server / web proxy in front of one. A non-loopback dedicated MCP bind requires it; serve enables protocol-layer MCP auth when it is set. Behind a proxy, set the same value on both services: the proxy spends the edge GITNEXUS_SERVE_AUTH_TOKEN, then replaces Authorization with this token on /api/mcp only. |
Dedicated MCP, a serve the client can reach directly, or a proxied deploy (Render Blueprint) where the backend runs protocol-layer MCP auth — configure it on the proxy too. |
GITNEXUS_PROFILE_DEFERRED |
unset | When 1, emits [deferred-profile] timing/progress logs for the post-chunk deferred resolution band (imports → heritage → buildHeritageMap → legacy call resolution). Implied by GITNEXUS_VERBOSE. |
Diagnosing analyze stalls in "Resolving calls (all chunks)" on large Java/Kotlin repos (issue #1741) without the full verbose ingestion noise. |
GITNEXUS_PROFILE_DEFERRED_SLOW_MS |
3000 (verbose) / 5000 |
Per-file threshold in ms above which processCallsFromExtracted emits a slow file … log line. Parsed via Number(): accepts integers (5000), scientific notation (2.5e3), decimals (.5), and hex (0x10). Non-finite or non-positive values fall back to the default. |
Hunting a few outlier files dominating the deferred call-resolution stage; lower to surface more, raise to focus only on the worst. |
PROF_LBUG_LOAD |
unset | When 1, emits one [lbug-load prof] summary line per loadGraphToLbug call breaking the graph-DB persistence wall into stages (csv-emit / copy-nodes / copy-rels / fallback / total) plus node & edge counts. Zero-cost when unset. |
Attributing large-repo analyze wall time across CSV generation vs. LadybugDB COPY (issue #2203) — the analyze "emit" timing is the scope-resolution bucket, not this DB-write path. |
GITNEXUS_MAX_FILE_SIZE |
512 (KB) |
Walker skip threshold in KB. Hard cap is 32768 (tree-sitter buffer ceiling). Equivalent to --max-file-size <kb>. |
Indexing repos with intentionally-large source files (generated parsers, vendored bundles) that should still be parsed. |
GITNEXUS_WORKER_SUB_BATCH_TIMEOUT_MS |
30000 |
Worker idle timeout in milliseconds before retry/fallback. Equivalent to --worker-timeout <seconds> × 1000. |
Slow-parsing files (large minified JS, deeply-nested TS types) that legitimately need more than 30s. |
GITNEXUS_WORKER_READY_TIMEOUT_MS |
5000 |
Startup budget in milliseconds for a parse worker to load its grammar bindings and report {type:'ready'}. Slots that miss it are treated as startup crashes. |
Slow or heavily loaded hosts where a full pool cold-starting concurrently needs more than 5s, and analyze aborts with "did not report ready within 5000ms". |
GITNEXUS_FTS_STEMMER |
porter |
Stemmer used when rebuilding BM25/FTS indexes. Use none for CJK-heavy repositories, or a language stemmer such as german, french, or spanish for matching repository comments. Re-run gitnexus analyze --repair-fts after changing it. |
Keyword search quality is poor for non-English comments or identifiers under English stemming. |
GITNEXUS_WAL_CHECKPOINT_THRESHOLD |
67108864 (64 MiB) |
LadybugDB WAL auto-checkpoint threshold in bytes. Equivalent to --wal-checkpoint-threshold <bytes>. -1 keeps LadybugDB's stock threshold (~16 MiB). Larger thresholds reduce checkpoint frequency but increase the WAL size at rotation time — choose a smaller value on disk-constrained environments. |
You need a larger or smaller WAL auto-checkpoint threshold for your analyze workload. |
GITNEXUS_LBUG_BUFFER_POOL_SIZE |
min(2 GiB, 80% RAM) | LadybugDB buffer-pool ceiling in bytes for every GitNexus database (analyze, MCP server, serve, group bridges). 0 restores LadybugDB's native unbounded default of 80% of system RAM; invalid values warn and fall back to the default (#2557). During analyze the pool is right-sized to the graph, scaled on non-4 KiB-page hosts by the page-size granule ratio up to min(2 GiB × pageSize/4 KiB, 80% RAM) (#2631); this env var overrides all of that as an absolute value. |
A long-lived gitnexus mcp or a big incremental analyze uses too much memory, or a huge repo's working set genuinely needs a pool larger than 2 GiB. |
GITNEXUS_LBUG_MAX_DB_SIZE |
17179869184 (16 GiB) |
Maximum size in bytes of a single LadybugDB database file — an mmap/disk-address-space ceiling, not a memory limit (it does not constrain the buffer pool). Invalid values silently fall back to the default. | Indexing a genuinely huge monorepo whose on-disk graph index approaches 16 GiB. |
GITNEXUS_WORKER_SUB_BATCH_MAX_BYTES |
8388608 (8 MB) |
Per-job byte budget the pool will send to a worker in one postMessage. |
Very large individual files; mostly diagnostic — bumping past 8 MB risks structured-clone memory pressure. |
GITNEXUS_WORKER_MAX_RESPAWNS_PER_SLOT |
3 |
Max replacement spawns per worker slot before the slot is dropped from the active rotation. Bounds respawn loops on a chronically-crashing slot. | Hosts where a flaky worker should retry more (raise) or fail-fast (lower) before the slot is dropped. |
GITNEXUS_WORKER_MAX_CUMULATIVE_TIMEOUT_MS |
5 × subBatchTimeoutMs |
Total retry wall-time budget per job before quarantining. Combined with timeoutBackoffFactor, prevents exponentially-growing retries from stalling for hours. |
Slow files that legitimately need long total retry windows; lower to fail-fast on stalls. |
GITNEXUS_WORKER_CONSECUTIVE_FAILURE_THRESHOLD |
max(3, poolSize) |
Per-slot consecutive deaths before the pool's circuit breaker trips. After tripping, every subsequent dispatch rejects until a fresh pool is created. | Hosts where a SIGSEGV-prone native grammar should trip the breaker sooner; CI runners that should fail loudly. |
GITNEXUS_WORKER_SHUTDOWN_DRAIN_MS |
30000 |
Max wait at pool shutdown for a retired worker still inside native code. The worker is terminated at its next JS-safe point instead of mid-native-call (which aborts the whole process with Napi::Error, #2432); on expiry it is left running, unref'd, and terminated when it surfaces. |
Shutdown latency matters more than draining a wedged worker (lower), or a legitimately-slow native grammar needs longer to surface (raise). |
GITNEXUS_CPP_CAPTURE_BUDGET_MS |
20000 |
Per-file wall-clock budget for C++ capture extraction. On breach the file keeps the captures accumulated so far and logs a warning — the worker returns to JS instead of stalling in native-heavy loops (#2432). 0 expires immediately. |
Pathological generated C++ that still exceeds the budget after the indexed lookups; raise for completeness, lower to fail-fast. |
GITNEXUS_CHUNK_BYTE_BUDGET |
2097152 (2 MB) |
Per-bucket byte budget for parse-cache packing. Files are grouped by (language, hash(path) mod 128); packs inside a bucket are cut at this limit. Smaller = finer-grained invalidation and more dispatch. Default is always 2 MiB and no longer scales with worker count. |
Tuning incremental-analyze cache invalidation on monorepos without changing --workers. |
GITNEXUS_NO_GITIGNORE |
unset | When set, skips .gitignore parsing. .gitnexusignore is still honored. |
Indexing a repo whose .gitignore excludes files you actually want indexed (e.g., generated code committed for cross-repo lookup). |
GITNEXUS_SKIP_OPTIONAL_GRAMMARS |
unset | When =1 strictly, skips the vendored grammar materialize for tree-sitter-dart, tree-sitter-proto, tree-sitter-swift, and tree-sitter-kotlin at install time (and the Dart/Proto source builds). Those four won't be parsed; the install still succeeds. |
Installing on a host without a C++ toolchain or where the vendored prebuilds don't match; willing to skip Dart/Proto/Swift/Kotlin parsing. |
GITNEXUS_MCP_READ_ONLY |
unset | Set to 1 to expose only proven single-repository read tools and resources; 0 disables the policy and any other value fails startup. |
The MCP server runs in an environment where graph mutation, raw Cypher, and cross-repository group routing must be unavailable. |
GITNEXUS_MCP_ALLOWED_REPOS |
unset | Comma-separated allowlist of canonical indexed repository names or absolute paths. Invalid, ambiguous, or blank entries fail startup. | One MCP process must expose only a bounded subset of the repositories in the global registry. |
GITNEXUS_MCP_DEFAULT_REPO |
unset | Canonical indexed repository name or absolute path used when a tool or resource omits its repository. Must belong to the allowlist when one is set. | Several repositories are available but unqualified MCP calls should resolve deterministically. |
GITNEXUS_MCP_DEFAULT_MAX_TOKENS |
unset | Default positive-integer response budget for MCP query, context, and impact, estimated at four UTF-8 bytes per token. Explicit maxTokens wins. |
Long MCP responses consume too much model context and callers cannot reliably add a per-request budget. |
GITNEXUS_PUBLIC_ORIGIN |
unset | The single browser origin serve is reached through, added to the CORS allowlist and to the write-route origin guard. A wildcard bind (0.0.0.0) has no host identity, so without this the server's own UI is refused. Setting it currently refuses to start: serve has no authentication, requests carrying no Origin header already reach POST /api/analyze and DELETE /api/repo, and this is the setting that would admit browser writes on top of that. Matching rules for when the gate lifts: the hostname must match exactly, and so must the scheme. A value with no scheme (app.example.com) means https, since a bare host comes from platform service discovery and those terminate TLS; spell out http://app.example.com for plain HTTP. An explicit port must match; with no port, any port on that hostname is accepted. Anything that is not one reachable host (a list, *, a bare port number, a :0 port, a trailing dot) warns at startup and allows nothing. |
gitnexus serve runs behind a reverse proxy or on a wildcard bind, and the UI's index/delete requests return origin_not_allowed. |
GITNEXUS_TRUST_PROXY |
loopback, linklocal, uniquelocal |
Express trust proxy value — which upstream hops may set X-Forwarded-*, and so what the per-IP rate limiter reads as the client IP. Set it to the exact number of proxies you control. Every hop past that is one more entry of the chain the caller gets to write. false/no/off (and a 0 hop count) trust no hop; a proxy list Express can compile (loopback, 10.0.0.0/8, 127.0.0.1) names them instead. true/yes/on is rejected: it reads the client-controlled leftmost X-Forwarded-For entry, so a spoofed chain earns a fresh rate-limit key per request, and express-rate-limit rejects it too (ERR_ERL_PERMISSIVE_TRUST_PROXY). Counts above 16 are rejected as well, as a sanity ceiling rather than a safety boundary. Any invalid value warns and falls back to the default. Bind non-loopback with this unset and serve warns: a load balancer outside the private ranges is untrusted, so every request keys to the balancer and the per-IP limit becomes one shared limit. |
serve sits behind a load balancer outside the private ranges (AWS ALB, Cloudflare, CGNAT), where every request otherwise collapses to the proxy hop and rate limiting goes global. |
gitnexus uninstall
gitnexus uninstall reverses gitnexus setup — it removes the GitNexus MCP entries, hooks, and skill directories it added to each detected editor. Skill directories are identified by bundled gitnexus skill name (e.g. gitnexus-cli/), so if you customized files inside an installed skill directory, back them up first. It is a dry-run preview by default and prints the exact paths it would remove; pass --force to apply. Per-repo indexes (gitnexus clean --all) and the global npm package (npm uninstall -g gitnexus) are left for you to remove.
Publishing to understand-quickly (opt-in)
looptech-ai/understand-quickly is a public registry of code-knowledge graphs that lists gitnexus@1 as a first-class format. After registering your repo once (npx @understand-quickly/cli add or the wizard), gitnexus publish fires a single repository_dispatch event so the registry resyncs your entry on demand instead of waiting for the nightly job.
It is opt-in and a no-op without UNDERSTAND_QUICKLY_TOKEN — a fine-grained GitHub PAT with Repository dispatches: write on the registry repo. Nothing else happens; no graph file is uploaded. See the protocol spec for the full contract.
How It Works
GitNexus builds a complete knowledge graph of your codebase through a multi-phase indexing pipeline:
- Structure — walks the file tree and maps folder/file relationships
- Parsing — extracts functions, classes, methods, and interfaces using Tree-sitter ASTs
- Resolution — resolves imports, function calls, heritage, constructor inference, and
self/thisreceiver types across files with language-aware logic - Clustering — groups related symbols into functional communities
- Processes — traces execution flows from entry points through call chains
- Search — builds hybrid search indexes for fast retrieval

Multi-Repo Architecture
GitNexus uses a global registry so one MCP server can serve multiple indexed repos. No per-project MCP config needed — set it up once and it works everywhere.
Each gitnexus analyze stores the index in .gitnexus/ inside the repo (portable, gitignored) and registers a pointer in ~/.gitnexus/registry.json. When an AI agent starts, the MCP server reads the registry and can serve any indexed repo. LadybugDB connections are opened lazily on first query and evicted after 5 minutes of inactivity (max 5 concurrent). Read-only tools can omit repo when only one repo is indexed, an MCP default is configured, or the GitNexus process cwd is inside a registered path without crossing into an unindexed nested Git checkout. Outside those paths—and for mutating tools with multiple indexed repos and no MCP default—pass repo explicitly.

Tool Examples
Impact Analysis
impact({target: "UserService", direction: "upstream", minConfidence: 0.8})
TARGET: Class UserService (src/services/user.ts)
UPSTREAM (what depends on this):
Depth 1 (WILL BREAK):
handleLogin [CALLS 90%] -> src/api/auth.ts:45
handleRegister [CALLS 90%] -> src/api/auth.ts:78
UserController [CALLS 85%] -> src/controllers/user.ts:12
Depth 2 (LIKELY AFFECTED):
authRouter [IMPORTS] -> src/routes/auth.ts
Options: maxDepth, minConfidence, relationTypes (CALLS, IMPORTS, EXTENDS, IMPLEMENTS), includeTests, limit (max symbols per depth, default 100), offset (pagination start per depth), summaryOnly (counts and risk only, omits symbol list)
Disambiguation — when several symbols share the target name, impact returns a ranked ambiguous candidate list instead of guessing. Narrow it with target_uid (exact, zero-ambiguity), file_path, or kind (Function, Class, Method, …). From the CLI these are --uid, --file, and --kind, matching gitnexus context:
gitnexus impact get_embeddings # → ambiguous: lists ranked candidates
gitnexus impact get_embeddings --file src/embed.py # → resolves to the one in that file
gitnexus impact get_embeddings --uid "Function:src/embed.py:get_embeddings" # exact

Wiki Generation
Generate LLM-powered documentation from your knowledge graph:
# Requires an LLM API key (OPENAI_API_KEY, etc.)
gitnexus wiki
# Use a custom model or provider (default model: minimax/minimax-m2.5)
gitnexus wiki --model gpt-4o
gitnexus wiki --base-url https://api.anthropic.com/v1
gitnexus wiki --provider grok # local Grok Build CLI (uses `grok login`, no API key)
# Force full regeneration
gitnexus wiki --force
# Increase the timeout or retries for large codebases or slow LLM providers
gitnexus wiki --timeout <seconds> # LLM request timeout in seconds (default: disabled)
gitnexus wiki --retries <n> # Max LLM retry attempts per request (default: 3)
# Allow a specific LAN/self-hosted HTTP LLM host (HTTPS is preferred for remote endpoints)
gitnexus wiki --base-url http://llama-box.local:8080/v1 --allow-insecure-connection llama-box.local
# Or set a comma-separated host allowlist:
GITNEXUS_ALLOW_INSECURE_CONNECTION=llama-box.local,192.168.1.23
# Change the output language
gitnexus wiki --lang <lang> # e.g. english, chinese, spanish, japanese
For safety, http:// LLM base URLs are allowed by default only for loopback hosts (localhost, 127.0.0.1, ::1). --allow-insecure-connection and GITNEXUS_ALLOW_INSECURE_CONNECTION accept exact hostnames or IP addresses only; do not include schemes, ports, paths, credentials, or wildcards.
The wiki generator reads the indexed graph structure, groups files into modules via LLM, generates per-module documentation pages, and creates an overview page — all with cross-references to the knowledge graph.
Web UI (browser-based)
A client-side graph explorer and AI chat — your code never leaves your machine.
Try it now: gitnexus.vercel.app — run npx gitnexus@latest serve locally and the page auto-connects to your local backend.
The web UI uses the same indexing pipeline as the CLI but runs entirely in WebAssembly (Tree-sitter WASM, LadybugDB WASM, in-browser embeddings). It's great for quick exploration but limited by browser memory for larger repos.
Local Backend Mode: run gitnexus serve and open the web UI — it auto-detects the server and shows all your indexed repos, with full AI chat support. No re-upload, no re-index. The agent's tools (Cypher queries, search, code navigation) route through the backend HTTP API automatically.
Run the frontend locally
git clone https://github.com/abhigyanpatwari/gitnexus.git
cd gitnexus/gitnexus-shared && npm install && npm run build
cd ../gitnexus-web && npm install
npm run dev
# Then in another terminal, start the backend the frontend connects to:
npx gitnexus@latest serve
Docker
docker compose up -d
This starts the server on http://localhost:4747 and the web UI on http://localhost:4173. The UI auto-detects the server because the browser runs on the host and reaches the container via the mapped port.
The official setup ships two signed images, published identically to GitHub Container Registry (GHCR) and Docker Hub — same build, same digest, same Cosign signature:
| Purpose | GHCR (default in docker-compose.yaml) |
Docker Hub mirror |
|---|---|---|
CLI / gitnexus serve backend (HTTP API on port 4747, MCP, indexer) |
ghcr.io/abhigyanpatwari/gitnexus:latest |
akonlabs/gitnexus:latest |
Static web UI (port 4173) |
ghcr.io/abhigyanpatwari/gitnexus-web:latest |
akonlabs/gitnexus-web:latest |
A named volume (gitnexus-data) persists the global registry, indexes, and cloned repos at /data/gitnexus inside the server container. To make repos on your host machine indexable, set WORKSPACE_DIR before bringing the stack up:
WORKSPACE_DIR=$HOME/code docker compose up -d
# Inside the server container the directory is mounted read-only at /workspace.
docker compose exec gitnexus-server gitnexus index /workspace/my-repo
Heads-up — image rename. Earlier releases published the web UI under
ghcr.io/abhigyanpatwari/gitnexus. That slug now hosts the CLI/server image and the UI moved toghcr.io/abhigyanpatwari/gitnexus-web. Previous tags remain pullable, but new versions are only published under the new slugs — update yourdocker run/ compose files (or just adopt the bundled compose).
Direct docker run & env file
# Server
docker run --rm -d \
--name gitnexus-server \
-p 4747:4747 \
-v gitnexus-data:/data/gitnexus \
ghcr.io/abhigyanpatwari/gitnexus:latest
# Web UI
docker run --rm -d \
--name gitnexus-web \
-p 4173:4173 \
ghcr.io/abhigyanpatwari/gitnexus-web:latest
Optional env file (override image tags, container names, ports, workspace dir):
cp .env.example .env
docker compose --env-file .env up -d
Files:
- Dockerfile.web — builds
gitnexus-sharedandgitnexus-web, then serves the production frontend. - Dockerfile.cli — builds the CLI/server (with its native deps) and runs
gitnexus serve --host 0.0.0.0. - docker-compose.yaml — starts both signed images side by side.
- .env.example — overrides for image names, container names, ports, and the workspace mount.
Versioning & supply-chain protection (Cosign signatures, provenance, Kubernetes admission policy)
The Docker images are version-locked to the npm package:
- Stable images are only published from
vX.Y.Zgit tags (viadocker.ymltriggered directly by the tag push), and the workflow refuses to build unless the tag exactly matchesgitnexus/package.json's version. Soghcr.io/abhigyanpatwari/gitnexus:1.6.2(and its Docker Hub mirrorakonlabs/gitnexus:1.6.2) is byte-for-byte the same release asnpm install gitnexus@1.6.2— no drift, no floating builds frommain. Both registries receive the same digest from a single build step, so you can pull from either and the signature verifies identically. - Release-candidate images (e.g.
:1.7.0-rc.1) are published alongside each RC npm release. They are built bypublish.ymlcallingdocker.ymlas a reusable workflow after the RC tag is created and pushed. :latestis auto-promoted only from non-prerelease tags by the Docker metadata action, so it always points at a real, npm-published version.
Both images are signed with Cosign keyless signing using the workflow's GitHub OIDC identity, and shipped with build provenance and SBOM attestations. This is your protection against supply-chain attacks: even if an attacker republishes a same-named image elsewhere (or somehow pushes to a typo-squatted registry), they cannot forge a Cosign signature tied to abhigyanpatwari/GitNexus's docker.yml. Always verify before pulling into sensitive environments.
Stable releases — signed from the v* tag ref:
cosign verify ghcr.io/abhigyanpatwari/gitnexus:1.6.2 \
--certificate-identity-regexp '^https://github\.com/abhigyanpatwari/GitNexus/\.github/workflows/docker\.yml@refs/tags/v[0-9]+\.[0-9]+\.[0-9]+(-[a-zA-Z0-9.]+)?$' \
--certificate-oidc-issuer https://token.actions.githubusercontent.com
# Same signature verifies the Docker Hub mirror (identical digest):
cosign verify docker.io/akonlabs/gitnexus:1.6.2 \
--certificate-identity-regexp '^https://github\.com/abhigyanpatwari/GitNexus/\.github/workflows/docker\.yml@refs/tags/v[0-9]+\.[0-9]+\.[0-9]+(-[a-zA-Z0-9.]+)?$' \
--certificate-oidc-issuer https://token.actions.githubusercontent.com
The regex pins the certificate identity to this repo's docker.yml workflow run from a v* tag — rejecting unsigned images, images signed by other workflows, and images signed from unprotected refs. It is identical for both registries because both sets of tags were signed at the same digest in one workflow run.
Release candidates — signed from refs/heads/main (the caller's ref when publish.yml invokes docker.yml as a reusable workflow):
cosign verify ghcr.io/abhigyanpatwari/gitnexus:1.7.0-rc.1 \
--certificate-identity 'https://github.com/abhigyanpatwari/GitNexus/.github/workflows/docker.yml@refs/heads/main' \
--certificate-oidc-issuer https://token.actions.githubusercontent.com
You can also inspect the build provenance and SBOM:
cosign download attestation ghcr.io/abhigyanpatwari/gitnexus:1.6.2 \
--predicate-type https://slsa.dev/provenance/v1
Kubernetes: enforce signatures at admission. Ship the bundled ClusterImagePolicy so the Sigstore policy-controller rejects any GitNexus pod whose image is not signed by this repo's docker.yml running from a vX.Y.Z tag — the same identity the cosign verify snippet above pins.
# 1. Install the controller (one-time, cluster-wide)
helm repo add sigstore https://sigstore.github.io/helm-charts && helm repo update
helm install policy-controller -n cosign-system --create-namespace \
sigstore/policy-controller
# 2. Opt your namespace in
kubectl label namespace <your-ns> policy.sigstore.dev/include=true
# 3. Apply the policy
kubectl apply -f deploy/kubernetes/cluster-image-policy.yaml
After this, attempting to deploy an unsigned image — or one signed by anything other than abhigyanpatwari/GitNexus's docker.yml at a v* tag — fails the admission webhook before a pod is ever created. This turns the verifiable signature into an enforced policy, which is the supply-chain control most clusters actually need.
