Text Case Converter
Convert selected text between 10 case formats directly in the editor: camelCase, PascalCase, snake_case, CONSTANT_CASE, kebab-case, Train-Case, Title Case, Sentence case, lower case, and UPPER CASE.
Features
- 10 one-click case conversions from the editor context menu
- Multi-cursor support — every non-empty selection is converted
- Unicode-aware tokenizer (handles camelCase input, uppercase runs, digits, hyphens, accents, and punctuation)
- Context menu entries appear only when there is a selection

Release
Releases are published automatically to the VS Code Marketplace by GitHub Actions when a version tag is pushed.
1. Set up the publish token (once)
- Go to the Visual Studio Marketplace publisher management page and select the
vheins publisher.
- Create a Personal Access Token with the Marketplace scope and Manage permission.
- In the GitHub repository, go to Settings → Secrets and variables → Actions and add the token as a repository secret named
VSCE_PAT.
2. Create a release
- Bump the
version field in package.json (the release workflow verifies it matches the tag).
- Commit the change:
git commit -m "chore: bump version to X.Y.Z".
- Tag and push:
git tag vX.Y.Z && git push origin vX.Y.Z.
The Release workflow runs the checks (lint, unit tests, packaging) and then publishes the extension with vsce publish. For workflow_dispatch runs, the published version is the one in package.json (version-to-tag verification is only enforced on tag pushes).
