* Support mentioning filenames with spaces
Allows spaces to be escaped in mentions with \. Does not attempt more
comprehensive escape handling. (IMO a more structured representation or
moving to something like @[something complex] is probably a better long
term approach, but the scope of that seems problematic.

Mention regex:
|
|
- **Purpose**:
|
|
- To identify and highlight specific mentions in text that start with '@'.
|
|
- These mentions can be file paths, URLs, or the exact word 'problems'.
|
|
- Ensures that trailing punctuation marks (like commas, periods, etc.) are not included in the match, allowing punctuation to follow the mention without being part of it.
|
|
|
|
- **Regex Breakdown**:
|
|
- `/@`:
|
|
- **@**: The mention must start with the '@' symbol.
|
|
|
|
- `((?:\/|\w+:\/\/)[^\s]+?|problems\b|git-changes\b)`:
|
|
- **Capturing Group (`(...)`)**: Captures the part of the string that matches one of the specified patterns.
|
|
- `(?:\/|\w+:\/\/)`:
|
|
- **Non-Capturing Group (`(?:...)`)**: Groups the alternatives without capturing them for back-referencing.
|
|
- `\/`:
|
|
- **Slash (`/`)**: Indicates that the mention is a file or folder path starting with a '/'.
|
|
- `|`: Logical OR.
|
|
- `\w+:\/\/`:
|
|
- **Protocol (`\w+://`)**: Matches URLs that start with a word character sequence followed by '://', such as 'http://', 'https://', 'ftp://', etc.
|
|
- `(?:[^\s\\]|\\ )+?`:
|
|
- **Non-Capturing Group (`(?:...)`)**: Groups the alternatives without capturing them.
|
|
- **Non-Whitespace and Non-Backslash (`[^\s\\]`)**: Matches any character that is not whitespace or a backslash.
|
|
- **OR (`|`)**: Logical OR.
|
|
- **Escaped Space (`\\ `)**: Matches a backslash followed by a space (an escaped space).
|
|
- **Non-Greedy (`+?`)**: Ensures the smallest possible match, preventing the inclusion of trailing punctuation.
|
|
- `|`: Logical OR.
|
|
- `problems\b`:
|
|
- **Exact Word ('problems')**: Matches the exact word 'problems'.
|
|
- **Word Boundary (`\b`)**: Ensures that 'problems' is matched as a whole word and not as part of another word (e.g., 'problematic').
|
|
- `|`: Logical OR.
|
|
- `terminal\b`:
|
|
- **Exact Word ('terminal')**: Matches the exact word 'terminal'.
|
|
- **Word Boundary (`\b`)**: Ensures that 'terminal' is matched as a whole word and not as part of another word (e.g., 'terminals').
|
|
- `(?=[.,;:!?]?(?=[\s\r\n]|$))`:
|
|
- **Positive Lookahead (`(?=...)`)**: Ensures that the match is followed by specific patterns without including them in the match.
|
|
- `[.,;:!?]?`:
|
|
- **Optional Punctuation (`[.,;:!?]?`)**: Matches zero or one of the specified punctuation marks.
|
|
- `(?=[\s\r\n]|$)`:
|
|
- **Nested Positive Lookahead (`(?=[\s\r\n]|$)`)**: Ensures that the punctuation (if present) is followed by a whitespace character, a line break, or the end of the string.
|
|
|
|
- **Summary**:
|
|
- The regex effectively matches:
|
|
- Mentions that are file or folder paths starting with '/' and containing any non-whitespace characters (including periods within the path).
|
|
- File paths can include spaces if they are escaped with a backslash (e.g., `@/path/to/file\ with\ spaces.txt`).
|
|
- URLs that start with a protocol (like 'http://') followed by any non-whitespace characters (including query parameters).
|
|
- The exact word 'problems'.
|
|
- The exact word 'git-changes'.
|
|
- The exact word 'terminal'.
|
|
- It ensures that any trailing punctuation marks (such as ',', '.', '!', etc.) are not included in the matched mention, allowing the punctuation to follow the mention naturally in the text.
|
|
|
|
- **Global Regex**:
|
|
- `mentionRegexGlobal`: Creates a global version of the `mentionRegex` to find all matches within a given string.
