the post-commit
hook will do: update ${FILENAME}
every time after git commit -am <message>
, so the "new" ${FILENAME}
actually won't be published into remote repository due to the status is modified
(instead of staged
).
So, is there any way that using git-hook to modify files in post-commit steps, and put changed file into staged
status (for push)?
Fyi: Slight bugfix update and added json output

@thom my usecase is actually similar, but you are right and I can actually do this at package creation time in the makefile: it's way cleaner and makes more sense. Thanks for the answer!
