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.

Out of the box, Smart Cleaner supports:

• JavaScript / TypeScript: //, /* ... */, strings, regex literals.
• Python: #, strings.
• Java / C / C++ / C# / Go / Rust: //, /* ... */.
• SQL / Lua: --, /* ... */ (SQL), --[[ ... ]] (Lua).
