ContextEditor

ContextEditor is a macOS app that routes text and source files to different editors depending on the current project.

It is designed for setups where one project should open in Cursor, another in VS Code, and another in Sublime Text, while macOS still uses a single default app in Finder.

How It Works

1. macOS sends the clicked file to ContextEditor.
2. ContextEditor walks up the directory tree looking for .contexteditor.
3. It reads the editor value.
4. It opens the file in the matching real editor app.
5. If there is no .contexteditor, it asks macOS for the real default app for that file type and avoids routing back into ContextEditor.

.contexteditor

Place a .contexteditor file at the root of a project:

{
  "editor": "cursor"
}

Supported values:

• cursor
• vscode
• code
• codium
• windsurf
• zed
• sublime
• sublimetext
• nova
• bbedit
• textmate
• coteditor
• macvim
• textedit

Download

Prebuilt signed binaries are available from the Releases page.

The current public release is v0.1.2.

Homebrew

brew tap driade/context-editor https://github.com/driade/context-editor
brew install --cask driade/context-editor/contexteditor

This tap installs the notarized app published in GitHub Releases.

Build

Requirements:

• macOS
• Xcode
• XcodeGen

git clone https://github.com/driade/context-editor.git
cd context-editor
xcodegen generate
./scripts/build_universal.sh

The app will be generated at:

build-universal/output/ContextEditor.app

That command builds a universal macOS app with Apple Silicon and Intel slices.

Tests

xcodebuild -project ContextEditor.xcodeproj -scheme ContextEditor -configuration Debug -derivedDataPath build test

The test suite covers configuration lookup and editor resolution behavior.

Use in Finder

1. Build ContextEditor.app.
2. In Finder, select any text or source file and open Get Info.
3. Under Open with, choose ContextEditor.
4. Click Change All....

Notes

• The app is registered as an editor for common text and source-code content types through its Info.plist.
• Finder associations are still controlled per file type by macOS, so you may need to use Get Info > Open with > Change All... for the file families you care about.
• GitHub release builds are signed, notarized, and published automatically from version tags.
