Explaining the problem more in-depth than the titular definition:
Often I merge branches into master and want to prune based on that. M-p works fantastic for removing the remote branches (eg origin/mergedbranch) but not the local branch (eg mergedbranch) that referenced it before. I'm left with branches like the in the screenshot below.
There seem to be a lot of cli git commands such as this SO answer, but I was wondering if there was a magit equivalent.
The refs buffer has options to filter to merged branches.
Quoting C-hig (magit)References Buffer:
‘y’ (‘magit-show-refs’)
This command lists branches and tags in a dedicated buffer. However if this command is invoked again from this buffer or if it is invoked with a prefix argument, then it acts as a transient prefix command
Therefore you can access that transient menu with yy1
Within the transient menu you can refine the view with
-M setting the value to the merge target
(E.g develop or main).
Then type y to execute the command, comparing against
HEAD. The refs list you are left with should only contain merged
branches.
Now highlight all the branches you would like to delete, then press k to delete the selection.2
Remember that you can set and save default transient values with C-xs and C-xC-s respectively.
1 or C-uM-x magit-show-refs,
or in Evil it's yryr.
2 or M-x magit-delete-thing,
or in Evil it's x.
There's no such command, but it wouldn't be hard to create one if you know a little emacs lisp and look at other magit-branch-* commands and the SO answers you mentioned. If you do, then please submit a pull-request.
