Smart Cleaner

Smart Cleaner is a professional-grade VSCode extension produced by Unique Creators. It intelligently removes comments from your source code while strictly preserving strings, regex literals, and other syntax elements.

Features

Intelligent Removal: Distinguishes between comments and code, including complex cases like:
- Strings (Single, Double, Backticks)
- Regex Literals (/pattern/flags in JS/TS)
- Nested structures
Clean Output:
- Comment-Only Lines: Completely removes lines that contain only comments, cleaning up whitespace and newlines.
- Block Comments: Properly handles multiline block comments and indentation.
- Smart Formatting: Automatically consolidates consecutive empty lines.
Smart Capabilities:
- Preserve Documentation: Option to keep JSDoc/DocStrings (/**, """) while removing code comments.
- Remove Debug Statements: Option to strip console.log, print, etc.
- Region Cleanup: Option to remove #region / #endregion tags.
Configurable: Support for custom comment markers for any language.
Non-Blocking: Asynchronous processing prevents UI freezes on large files, with a cancellable progress indicator.

JavaScript / TypeScript: //, /* ... */, strings, regex literals.
