Add changelog item to ”COMMIT_EDITMSG” buffer

[baby-gnu]

Hello,

I recently switch from DVC to magit since I exclusively use git now.

I install magit from MELPA and wonder if some of my DVC workflow could be done with magit:

1. Edit files
2. Review modification before commit (I divert some vc command)
3. Stage changes
4. Run the commit to fill the log
5. Type subject and basic explanation of “why the commit”
6. Add per file summary of changes

Today, I'm doing points 1 to 5 with magit by diverting some vc command to use their prefix keys (without disturbing other backend).

The point 6 is the one I'm looking for, with DVC, when on a hunk, I hit C-x 4 a and it insert to the “COMMIT_EDITMSG” buffer the following line

* path/to/file (function name): <POINT>

with point position denoted by the <POINT> place holder.

Looking at add-change-log-entry, I think it could be split in several pieces to be more useful to others.

I should have read more carefully the code of magit, I found the magit-commit-add-log which does the job.

I just need to bind a keymap for it:

;; Insert commit log entry
(define-key magit-mode-map (kbd "M-l") 'magit-commit-add-log)
