Variable Conversion
A powerful variable naming and path style conversion extension for VS Code
Marketplace ·
OpenVSX ·
GitHub ·
Gitee
Supports one-key conversion and cyclic conversion, and can be used through the context menu, keyboard shortcuts, the status bar, and more.
- ✅ Multi-selection support
- ✅ Multiple editor windows support
- ✅ Undo & redo support (Ctrl + Z / Ctrl + Y)
- ✅ Enable only the target conversion formats you need
How to Use
Cyclic conversion
Select what you want to convert in the editor, then press Ctrl + Alt + [ or Ctrl + Alt + ] to cycle through the available naming conventions.
Basic conversion
1. Select the text to convert
2. Press Shift + Alt + T
Or click the Variable Conversion button in the status bar.
Or right-click → Variable Conversion.
Or right-click on the selected text → Convert string to....
3. Select the conversion target — and you're done.
Path Conversion (Beta)
This feature is still in Beta. If you encounter any problems, please let us know via the contact information at the end of this document.
Path conversion works the same way as variable conversion — through the context menu, the status bar, or keyboard shortcuts. The only difference is the shortcuts:
- Next path style:
Ctrl + Alt + /
- Previous path style:
Ctrl + Alt + Shift + /
Note: Only Windows-style and Unix-style paths are supported for now, so both shortcuts currently do the same thing. More path styles are planned (e.g. Windows Git Bash style, browser file:// protocol).
