There's been a discussion in the GIMP community about setting up git repos to host contributed assets like scripts, plug-ins and brushes, to replace the long-stagnant GIMP Plug-in Repository. One of the suggestions involves having lots of tiny git repos rather than one that holds all the assets.
That got me to thinking about one annoyance I always have when setting up a new git repository on github: the repository is initially configured with an ssh URL, so I can push to it; but that means I can't pull from the repo without typing my ssh password (more accurately, the password to my ssh key).
Fortunately, there's a way to fix that: a git configuration can have
url for pulling source, and a different
for pushing changes.
These are defined in the file
.git/config inside each
repository. So edit that file and take a look at the
[remote "origin"] section.
For instance, in the GIMP source repositories, hosted on git.gnome.org,
instead of the default of
url = ssh://git.gnome.org/git/gimp
I can set
pushurl = ssh://git.gnome.org/git/gimp url = git://git.gnome.org/gimp(disclaimer: I'm not sure this is still correct; my gnome git access stopped working -- I think it was during the Heartbleed security fire drill, or one of those -- and never got fixed.)
For GitHub the syntax is a little different. When I initially set up
a repository, the url comes out something like
url = firstname.lastname@example.org:username/reponame.git
(sometimes the git@ part isn't included), and the password-free
pull URL is something you can get from github's website. So you'll end
up with something like this:
pushurl = email@example.com:username/reponame.git url = https://github.com/username/reponame.git
That's helpful, and I've made that change on all of my repos.
But I just forked another repo on github, and as I went to edit
.git/config I remembered what a pain this had been to
do en masse on all my repos; and how it would be a much bigger
pain to do it on a gazillion tiny GIMP asset repos if they end up
going with that model and I ever want to help with the development.
It's just the thing that should be scriptable.
However, the rules for what constitutes a valid git passwordless pull URL, and what constitutes a valid ssh writable URL, seem to encompass a lot of territory. So the quickie Python script I whipped up to modify .git/config doesn't claim to handle everything; it only handles the URLs I've encountered personally on Gnome and GitHub. Still, that should be useful if I ever have to add multiple repos at once. The script: repo-pullpush (yes, I know it's a terrible name) on GitHub.
