Add a running log of git command output. #516

wants to merge 1 commit into from

3 participants


As well as the magit-process buffer (showing the output of the most recent git command), it would be mightily useful if that output was also appended to a magit-process-log buffer, so that we could see things like the commit hash for the stash that we dropped a couple of commands ago, and then realised that we wanted back (for example :)


Branch phil-s/process-log (branched from maint) implements this.


The change proposed by @phil-s is in #516. Closing this as there is no need to have two issues.

I know I made a mess of submitting this, but I'm confused by the last comment. You say the proposed change is in #516, but that is THIS issue, which you have just closed as a duplicate (of...?) I thought I'd already closed the duplicates, so it's not clear to me if I'm missing something, or if closing this issue was actually a mistake (although if the latter, it was probably caused by all my initial confusion over how to submit this in the first place!)


Probably the latter :-/

I could like to have that feature too, but so far did not care to write it.

But I would certainly not mind if someone else wrote it. Unfortunately your implementation is not good enough.

Things that come to mind:

  • default-directory has to be logged
  • a separator like ^L between entries
  • way to limit the number of logs to be kept
  • alternatively log directly to file
  • only log calls to magit-run* "that matter" (good luck with that)
  • (related but not same as above:) only log in certain repositories
  • command to toggle logging

@tarsius thanks for this excellent list. I picked up the idea of @phil-s and made progress, but will need to consider your suggestions before submitting.


Please also consider that magit-run* is already a mess, best not to make it any worse :-)


I notice that I messed up by not updating the log buffer in magit-process-sentinel, when the process has exited, meaning that I missed most of the output. I imagine that @ncalexan has done that properly.


I am closing this as it won't be merged in its current form. @ncalexan please open a new pull request when you are ready.
