I find it much easier to use direnv and set GIT_AUTHOR_EMAIL in each of ~/work/.envrc and ~/personal/.envrc No need to reconfigure every repo this way.
Just a note of caution, when this feature was added tools based on libgit2 did not understand it. I just checked now, libgit2 eventually added support (though it took 5 months since I filed the ticket). But if you're using any tools that have a 3-year-old version of libgit2 they might not understand it.
I do the same. Also remember the following keyword if you use nested .envrc files: source_up
If you don't use this in any nested envrc files, the settings don't carry over which means your git settings are not maintained. It is kind of an escape hatch as the parent files are not verified in the same way normal envrc files are, but I have found the trade off to be worth it
Nice! I was thinking of something like this recently, but decided instead to completely divorce personal and work projects. It’s nice to close the work laptop and go open the personal laptop knowing it’s impossible to cross the streams, as well as for the ritual.
I'm not entirely sure, but `:` means "true" in bash, and if I omit it, something like this happens:
$ git config alias.foo '! echo "$1";'
$ git foo bar
bar
echo "$1";: bar: command not found
Whereas if I end with `; :` then it works as expected:
$ git config alias.foo '! echo "$1"; :'
$ git foo bar
bar
It seems to execute the last argument (`bar`) as a command without the `:` at the end, and I don't have a `bar` command on my PATH so it angrily fails with exit code 127. If it instead executes `:` however, that will make it happily exit with 0.
It seems to be a Git alias quirk, but I may be incorrect here.
Huh I had no idea $1/$2/etc worked as-is in an alias. The advice I learned years ago for dealing with any alias that needs to do something custom with parameters is to write it like
git config alias.foo '!f() { actual command goes here }; f'
as that will pass all the args to the shell function. But if git is already setting it up so the args work then suffixing the alias with ";:" seems simpler.
