Peter-Bot 51b6d6abec feat: add local TeXLive as alternative LaTeX compilation backend ... Tectonic's limited package support makes it unusable for academic work with custom .sty/.cls files. This adds opt-in support for shelling out to a locally installed TeXLive distribution. Backend (latex.rs): - compile_with_texlive(): multi-pass compilation (2-3 engine passes + optional bibtex/biber), with xdvipdfmx fallback for .xdv → .pdf - find_texlive_binary(): resolves binaries via PATH, standard install locations, and macOS login-shell fallback for GUI apps - detect_bib_tool(): scans .tex for biblatex/bibliography to choose biber vs bibtex - texlive_env_path(): injects TeXLive bin dir into subprocess PATH so xelatex can find xdvipdfmx internally - detect_texlive Tauri command: reports available engines and version - compile_latex gains use_texlive parameter; error messages show which backend ran (e.g. "Compilation failed (TeXLive/xelatex)") - All paths passed to TeX are relative to avoid tilde expansion in iCloud paths (com~apple~CloudDocs) Frontend: - New settings-store.ts with persisted compilerBackend preference - Backend selector dropdown in PDF preview toolbar - All compile call sites pass the setting through to the backend - detectTexlive() and TexliveStatus for engine availability checks Tectonic remains the default. TeXLive is opt-in via the toolbar dropdown. All existing tests pass (152/152). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>		2026-03-27 00:02:38 +01:00
