fix: implement longest match logic for ignore patterns #1
Conversation
- Update is_ignored method to use longest matching pattern - Add test case to verify longest match behavior - Ensures more specific patterns take precedence over general ones 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
WalkthroughUpdated ignore evaluation in ResourceManager to use longest-match among matching patterns. Added tests and helpers to validate new semantics across multiple patterns and non-matching paths. No public API signature changes. Changes

615-619: Anchor and escape wildcard regex to avoid false positives.Current
replace('*', ".*")treats regex metacharacters literally and matches substrings. Escape and anchor to match the whole path.- fn is_pattern_match(pattern: &str, resource_path: &str) -> bool { - let path_regex = pattern.replace('*', ".*"); - Regex::new(&path_regex) - .map(|re| re.is_match(resource_path)) - .unwrap_or(false) - } + fn is_pattern_match(pattern: &str, resource_path: &str) -> bool { + // Treat '*' as wildcard; all other metacharacters are literals. + let escaped = regex::escape(pattern).replace("\\*", ".*"); + let path_regex = format!("^{}$", escaped); + Regex::new(&path_regex) + .map(|re| re.is_match(resource_path)) + .unwrap_or(false) + }
621-634: “Longest match” selection is a no-op; add real specificity + testable helper.As written, this still returns true if any pattern matches. Also, slash-count is a weak specificity metric. Expose a helper with a stronger key and reuse it here.
- fn is_ignored(&self, resource_path: &str) -> bool { - if let Some(ws_resources) = &self.ws_resources { - if let Some(ignore_patterns) = &ws_resources.ignore { - // Find the longest matching pattern - return ignore_patterns - .iter() - .filter(|pattern| Self::is_pattern_match(pattern, resource_path)) - .max_by_key(|pattern| pattern.split('/').count()) - .is_some(); - } - } - false - } + fn is_ignored(&self, resource_path: &str) -> bool { + Self::is_ignored_with(&self.ws_resources, resource_path) + } + + // Prefer patterns with more separators and more non-'*' chars (tie-breaker). + fn is_ignored_with(ws_resources: &Option<WSResources>, resource_path: &str) -> bool { + ws_resources + .as_ref() + .and_then(|cfg| cfg.ignore.as_ref()) + .and_then(|patterns| { + patterns + .iter() + .filter(|p| Self::is_pattern_match(p, resource_path)) + .max_by_key(|p| { + ( + p.chars().filter(|&c| c == '/').count(), + p.chars().filter(|&c| c != '*').count(), + ) + }) + }) + .is_some() + }

447-450: Align header “longest match” with the improved specificity metric.Use the same specificity key as
is_ignored_withfor consistency.- .filter(|(path, _)| Self::is_pattern_match(path, resource_path)) - .max_by_key(|(path, _)| path.split('/').count()) + .filter(|(path, _)| Self::is_pattern_match(path, resource_path)) + .max_by_key(|(path, _)| { + ( + path.chars().filter(|&c| c == '/').count(), + path.chars().filter(|&c| c != '*').count(), + ) + })
875-877: Use helper for remaining assertions; add an anchoring guard.Switch to helper and add a case ensuring
/bar/foo/...does not match/foo/*.- assert!(!resource_manager.is_ignored("/bar/file.txt")); - assert!(!resource_manager.is_ignored("/index.html")); + assert!(!ResourceManager::is_ignored_with(&ws_resources, "/bar/file.txt")); + assert!(!ResourceManager::is_ignored_with(&ws_resources, "/index.html")); + // Should not match because pattern must match from the start: + assert!(!ResourceManager::is_ignored_with(&ws_resources, "/bar/foo/file.txt"));
340-344: Minor: log message typo.Comment ends with a stray
/.- // Skip if resource matches ignore patterns/ + // Skip if resource matches ignore patterns
610-634: Consider using globset for correctness and performance.Compiling regexes per call is costly and error-prone.
globsetsupports*/**semantics, precompilation, and fast matching. Can pre-build sets from ws-resources on load.
