🔬 Detailed Features
📂 Regions View
- Displays a structured tree view of all regions in the current file.
- Automatically reveals and highlights the cursor’s active region (this can be toggled on/off with commands/settings).
- Click a region to instantly navigate to it.
🏛 Full Outline View
- Combines all regions and language symbols (classes, methods, variables, etc) into a unified tree view for the current file.
- Just like the Regions View, the cursor's active region/symbol is automatically revealed and highlighted, and this behavior can be toggled on/off.
- Click any item to instantly navigate to it.
⚠️ Region Diagnostics
- Detects unmatched region boundaries and adds warnings in both the editor (blue squiggles) and the Problems panel, helping you catch incomplete or misplaced regions quickly.
🔍 Go to Region...
- Like VSCode’s built-in "Go to Symbol...", but for regions:
- Opens a fuzzy-searchable dropdown to jump to any region in the current file.
- 📌 Default Keybinding:
- Windows/Linux:
Ctrl + Shift + R
- Mac:
Cmd + Shift + R
🐇 Go to Region Boundary
- Like VSCode’s built-in "Go to Bracket", but for regions:
- Jumps between matching start and end region boundaries.
- Jumps to the next region if the cursor is not already inside a region.
- 📌 Default Keybinding:
Alt + M
⏭ Go to Next / Previous Region
- Jumps to the next or previous region in the file.
- 📌 Default Keybindings:
- Next Region:
Ctrl + Alt + N
- Previous Region:
Ctrl + Alt + P
🎯 Select Current Region
- Selects the entire active region containing the cursor.
- 📌 Default Keybinding:
Alt + Shift + M
⚙️ Settings
🙈 Show/Hide Views
To quickly show or hide the Regions or Full Outline views, you can use the following commands and associated settings:
- Show/Hide Region View
- Commands:
Show Regions View / Hide Regions View
- Setting:
regionHelper.shouldShowRegionsView
- Show/Hide Full Outline View
- Commands:
Show Full Outline View / Hide Full Outline View
- Setting:
regionHelper.shouldShowFullOutlineView
🔄 Toggling Auto-Highlighting/Revealing in Tree Views
- By default, the Regions and Full Outline views will automatically reveal and highlight the cursor's active region or symbol as you navigate the editor.
- If you ever want to disable this auto-revealing behavior (e.g. for a more stable scroll position), you can use the
{Stop/Start} Auto-Highlighting Active {Region/Item} commands, or click the tree view's title bar action to toggle it on/off:
🔧 Custom Region Patterns
- Supports nearly 50 languages out of the box, including:
- C, C++, C#, Java, Python, JavaScript, JSX, TypeScript, TSX, PHP, Ruby, Swift, Go, Rust, HTML, XML, Markdown, JSON/JSONC, YAML, SQL, and more.
- Define your own custom region patterns, or adjust the existing default patterns, to customize how regions are parsed.
- Setting:
regionHelper.regionBoundaryPatternByLanguageId
📡 Extension API
Region Helper provides an API for accessing code regions and full outline symbols programmatically. You can use it to build region-aware tools for VSCode without having to write your own file-parsing logic.
See the full API documentation for details and examples.
🚀 Installation
- Install Region Helper from the VSCode Marketplace.
- ???
- Profit!
(Really, things should work out of the box. Let me know if they don't!)
🚧 Known Limitations
- 🔍 Go to Region... only supports camelCase matching (not full fuzzy search) due to a VSCode API limitation.
- The 📁 Regions and 🏛 Full Outline tree views always highlight the cursor's last active item, even when outside any region/symbol (another VSCode API limitation).
