This is a tool that deletes all of your git branches that have been "squash-merged" into master.
This is useful if you work on a project that squashes branches into master. After your branch is squashed and merged, you can use this tool to clean up the local branch.
$ npm install --global raquelxmoss/git-delete-squashed
$ git-delete-squashed--dry-run prints a list of the branches that would be deleted, but does not delete them.
To determine if a branch is squash-merged, git-delete-squashed creates a temporary dangling squashed commit with git commit-tree. Then it uses git cherry to check if the squashed commit has already been applied to master. If so, it deletes the branch.
