Making a pull request for a Julia package
I just wanted to document my workflow for making a pull request to a Julia package. Let us say that there’s a package called
MyPackage located on GitHub, which you have already installed in local Julia installation.
First, from the Julia REPL, we run
julia> using Revise pkg> develop MyPackage
This clones the
MyPackage git repo to the location
./julia/dev/MyPackage and activates this version.
In principle, you can now go ahead and play with this package and make commits. However, we’d like to be a bit more systematic. Let’s say you would like to contribute an awesome new feature to this package. First, we fork the repo on GitHub to
hershsingh/MyPackage, by just clicking
Fork at the top-right corner of the original repository in the GitHub web interface.
Now, we can add the forked repo as a remote on our local repo at
./julia/dev/MyPackage. This will allow us to push changes this this forked repo. Navigate to the local repo for this package from terminal and run:
$ cd .julia/dev/MyPackage $ git remote -v
At this point, running
git remote -v will only show the
origin for package, which is the main repo for this package. We can add our forked repo as a new remote:
$ git remote add myfork firstname.lastname@example.org:hershsingh/MyPackage $ git remote -v
Now, you should see both
myfork in the output of
git remote -v.
Once you have added the remote, then you can go ahead and make the changes to your package. Create a new branch, say
awesome-feature, and commit a bunch of changes to it. Now we can push this new branch into the remote.
$ git push myfork awesome-feature
Once you have pushed the changes to the remote repo, you can go ahead and create a pull request on GitHub. Usually, GitHub will automatically detect that you pushed a new branch and offer you to create a pull request. That’s it!
