From dd961d18a8a7a71f6890a09a8fd86cab69ad392c Mon Sep 17 00:00:00 2001 From: sam hoang Date: Sun, 2 Mar 2025 23:56:35 +0700 Subject: [PATCH 1/2] feat(mentions): improve path handling for Windows and escaped spaces Enhance the mention regex to properly support: - Windows paths with drive letters (C:\folder\file.txt) - Windows network shares (\\server\share\file.txt) - Windows relative paths (folder\file.txt) - Paths with escaped spaces in both Unix and Windows formats - Maintain compatibility with existing URL, git hash, and keyword patterns - Add comprehensive test suite with 200+ test cases validating all path formats and edge cases to ensure reliable pattern matching across platforms. --- src/shared/__tests__/context-mentions.test.ts | 233 ++++++++++++++++++

- - 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-Whitespace Characters (`[^\s]+`)**: Matches one or more characters that are not whitespace. - - **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). - - 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. + 1. **Pattern Components**: + - The regex is built from multiple patterns joined with OR (|) operators + - Each pattern handles a specific type of mention: + - Unix/Linux paths + - Windows paths with drive letters + - Windows relative paths + - Windows network shares + - URLs with protocols + - Git commit hashes + - Special keywords (problems, git-changes, terminal) + + 2. **Unix Path Pattern**: + - `(?:\\/|^)`: Starts with a forward slash or beginning of line + - `(?:[^\\/\\s\\\\]|\\\\[ \\t])+`: Path segment that can include escaped spaces + - `(?:\\/(?:[^\\/\\s\\\\]|\\\\[ \\t])+)*`: Additional path segments after slashes + - `\\/?`: Optional trailing slash + + 3. **Windows Path Pattern**: + - `[A-Za-z]:\\\\`: Drive letter followed by colon and double backslash + - `(?:(?:[^\\\\\\s/]+|\\/[ ])+`: Path segment that can include spaces escaped with forward slash + - `(?:\\\\(?:[^\\\\\\s/]+|\\/[ ])+)*)?`: Additional path segments after backslashes + + 4. **Windows Relative Path Pattern**: + - `(?:\\.{0,2}|[^\\\\\\s/]+)`: Path prefix that can be: + - Current directory (.) + - Parent directory (..) + - Any directory name not containing spaces, backslashes, or forward slashes + - `\\\\`: Backslash separator + - `(?:[^\\\\\\s/]+|\\\\[ \\t]|\\/[ ])+`: Path segment that can include spaces escaped with backslash or forward slash + - `(?:\\\\(?:[^\\\\\\s/]+|\\\\[ \\t]|\\/[ ])+)*`: Additional path segments after backslashes + - `\\\\?`: Optional trailing backslash + + 5. **Network Share Pattern**: + - `\\\\\\\\`: Double backslash (escaped) to start network path + - `[^\\\\\\s]+`: Server name + - `(?:\\\\(?:[^\\\\\\s/]+|\\/[ ])+)*`: Share name and additional path components + - `(?:\\\\)?`: Optional trailing backslash + 6. **URL Pattern**: + - `\\w+:\/\/`: Protocol (http://, https://, etc.) + - `[^\\s]+`: Rest of the URL (non-whitespace characters) + + 7. **Git Hash Pattern**: + - `[a-zA-Z0-9]{7,40}\\b`: 7-40 alphanumeric characters followed by word boundary + + 8. **Special Keywords Pattern**: + - `problems\\b`, `git-changes\\b`, `terminal\\b`: Exact word matches with word boundaries + + 9. **Termination Logic**: + - `(?=[.,;:!?]?(?=[\\s\\r\\n]|$))`: Positive lookahead that: + - Allows an optional punctuation mark after the mention + - Ensures the mention (and optional punctuation) is followed by whitespace or end of string + +- **Behavior Summary**: + - Matches @-prefixed mentions + - Handles different path formats across operating systems + - Supports escaped spaces in paths using OS-appropriate conventions + - Cleanly terminates at whitespace or end of string + - Excludes trailing punctuation from the match + - Creates both single-match and global-match regex objects */ -export const mentionRegex = - /@((?:\/|\w+:\/\/)[^\s]+?|[a-f0-9]{7,40}\b|problems\b|git-changes\b|terminal\b)(?=[.,;:!?]?(?=[\s\r\n]|$))/
