Squasher

Squash multiple local Git commits into one, directly from the VS Code Source Control Graph.

Features

• Right-click in the Source Control Graph: multi-select commits (Ctrl+click) and choose Squash Commits.
• Command Palette fallback: run Squasher: Squash Commits... to pick commits from a list.
• Opens the concatenated commit messages in an editor so you can craft the final message.
• Runs git reset --soft <oldest>^ followed by git commit -F <message> - with automatic rollback to ORIG_HEAD on failure.
• Prompts to auto-stash / pop uncommitted changes so the working tree is clean for the squash.

Requirements

• VS Code 1.93+ with the built-in Git extension enabled.
• git available on the PATH.

Installation

Squasher relies on the contribSourceControlHistoryItemMenu proposed API, so it cannot be published to the VS Code Marketplace until that API stabilizes. In the meantime, install the signed VSIX from the GitHub Releases page:

1. Download squasher-<version>.vsix from the latest release.

2. Install it — either via Extensions view → … menu → Install from VSIX… or:

   code --install-extension squasher-<version>.vsix
   

3. Launch VS Code with proposed APIs enabled for this extension:

   code --enable-proposed-api timheuer.squasher
   

   Add that flag to your shortcut/launcher so you don't have to type it every time.

Limitations

• Selected commits must be contiguous and end at the current HEAD of a named branch. Use interactive rebase for mid-history or non-contiguous squashes.
• The root commit cannot be the oldest commit in a squash (it has no parent to reset to). Use git rebase --root -i for that.
• Merge commits are not supported.
• The Source Control Graph view is single-select only (a VS Code limitation), so right-click squashes always run from the picked commit up to HEAD. Use the Command Palette (Squasher: Squash Commits...) for an explicit multi-pick.
• If the commits have already been pushed, you will need to force-push afterwards — Squasher does not do this automatically.
• The Source Control Graph context menu relies on the scm/historyItem/context menu id. The Command Palette command works regardless.
