SmartFile Implementation Hints

listFileTree Function Enhancement (ts/fs.ts:367-415)

Issue Fixed

The listFileTree function previously had inconsistent behavior with **/*.extension patterns across different systems and glob implementations. Some implementations would miss root-level files when using patterns like **/*.ts.

Solution Implemented

Modified the function to explicitly handle **/ patterns by:

1. Detecting when a pattern starts with **/
2. Extracting the file pattern after **/ (e.g., *.ts from **/*.ts)
3. Running both the original pattern and the extracted root pattern
4. Using a Set to deduplicate results and ensure consistent ordering

Key Benefits

• Guarantees consistent behavior across all systems
• Ensures both root-level and nested files are found with **/* patterns
• Maintains backward compatibility
• No performance degradation due to efficient deduplication

Test Coverage

Added comprehensive tests to verify:

• Both root and nested files are found with **/*.ts
• No duplicate entries in results
• Edge cases with various file extensions work correctly

This fix ensures tools like tsbuild check **/*.ts work reliably across all systems.
