Usage

Run the DiffHub git diff viewer in cmux or a browser and choose a base branch.

cmux


npx diffhub@latest cmux

Run that inside any git repository. DiffHub starts the local viewer and opens it in a cmux browser split.

cmux mode currently expects cmux.app on macOS at /Applications/cmux.app.

Use these flags when you need them:


# Use a different base branch
diffhub cmux --base develop

# Point at a repo in another directory
diffhub cmux --repo ~/projects/my-app
