Cargo Lens for Rust (VS Code Extension)

Adds CodeLens helpers above comments in Rust (.rs) files that contain cargo commands. When the extension finds cargo in a comment it will:

• If the cargo command appears inside single backticks (...), it will take the full content inside the backticks as the command.
• Otherwise it will try to intelligently grab the cargo command text near cargo (up to punctuation like . ; ! ? or end of comment).
• Place multiple CodeLens actions above the comment:
  • "Run: " — opens an integrated terminal and runs the command (focused).
  • "Run in background: " — runs the command in a terminal but does NOT focus the terminal (background).
  • "Copy: " — copies the command text to the clipboard.

Install / build

• npm install
• npm run compile
• In VS Code press F5 to launch an Extension Development Host for testing.

Activation

• The extension activates for Rust files (language id rust).

Notes & Limitations

• Heuristic parsing — it tries to be helpful but might not be perfect for every comment style.
• Multi-command comments may produce multiple lenses.
• Background run creates a terminal and does not focus it; the terminal is still visible in the Terminal panel if the user opens it.
• You can modify the heuristics in extractCargoCommandsFromComment to fine-tune command extraction.

Ideas for further improvements:

• Add settings to choose working directory (file folder vs workspace root).
• Allow configuring whether the background command should show the terminal panel or be fully hidden.
• Add a "Run with args..." input box.
