When I run built-in magit commands, they output to the magit-process buffer. How can I do the same with a custom magit command that generates shell output?
You can run one-off commands using the
magit-run-popup bound to
!!ls-files will run
git ls-files in the top-level
directory of the repo and output the results to the Magit process
buffer for that repo.
For writing your own commands, you can use one of
Magit's functions for calling Git,
picking the variant depending on the type of Git command and whether
you are calling it for a return value or for a side-effect. The
command from above ends up calling
(magit-run-git-async "ls-files") in the top-level directory of the repo.
