Functions

f
handleWatchEvent(
config: Config,
extensions: string[],
event: string,
filePath: string,
onEventFunc: (
event: string,
file: string
) => unknown,
onFinishFunc: ((
path: string,
event: string
) => void) | null | undefined
): void

Routes a file-system event to fsTree mutation and optional rebuild trigger. unlinkDir bypasses the extension filter so deleted directories always clean up fsTree.

f
mutateFSTree(
fsTree: FSTree,
event: string,
path: string
): void

Mutates fsTree in place based on a chokidar file-system event.

f
setupFileWatchers(
testFileLookupPaths: string[],
config: Config,
onEventFunc: (
event: string,
file: string
) => unknown,
onFinishFunc: ((
path: string,
event: string
) => void) | null | undefined
): { fileWatchers: Record<string, FSWatcher>; killFileWatchers: () => Record<string, FSWatcher>; }

Starts fs.watch watchers for each lookup path and calls onEventFunc on JS/TS file changes, debounced via a flag. Uses config.fsTree to distinguish unlink (tracked file) from unlinkDir (directory) on deletion.
