A lightweight VS Code extension that provides outline navigation (functions & namespaces with nesting) for Tcl scripts — improving productivity for engineers working with CAD flows, EDA tooling, or Tcl-based automation.

📦 Published on Visual Studio Marketplace
⭐ Used by engineers at Intel and beyond to accelerate Tcl workflow navigation.

• Adds symbols view in the VS Code outline explorer for Tcl proc and namespace definitions.
• Nested view for easier navigation in complex scripts.
• Compatible with standard Tcl language support extensions.
• Actively improved based on community feedback.

Example:

1. Install Tcl language support in VS Code.
2. Search “Tcl Outline” in the VS Code Marketplace or click here.
3. Reload VS Code and start coding in Tcl.

• proc block may close early if there is a string containing multiple } characters.
• Currently requires a Tcl language extension installed.
• Cursor context highlighting is limited to symbol declarations.

• Improved regex to catch more proc types.
• Fixed curly-bracket block alignment (empty procs supported).
