Building Documentation for Git Hub Pages

Creating a Git Hub project page

Git Hub pages are built from a branch of the repository called gh-pages. If you have not already created a Git Hub project pages for PyCBC in your repository, make a gh-pages branch in your repository as follows:

git checkout --orphan gh-pages
git rm -rf .
git clean -dxf
touch .nojekyll
mkdir latest
git add .nojekyll latest
git commit -a -m "set up gh-pages branch"
git push origin gh-pages
git branch --set-upstream gh-pages origin/gh-pages

These commands create the branch and then remove all of the files from this branch, so that it will just contain the documentation pages.


The main ligo-cbc/pycbc repository already has a gh-pages branch, so do not do this in the main repository.

Building and pushing the documentation

The documentation should built from the source code on a regular branch and installed into the gh-pages branch. Since git cannot have two branches checked out simultaneously, you need to check out another copy of the repository with the gh-pages branch inside your PyCBC source repository. Do this will the following commands (assuming your PyCBC git repository is in a directory named pycbc).

cd /path/to/your/repo/pycbc
git clone _gh-pages

Now flush the contents of this directory. We do this, as the documentation is not really under version control in the gh-pages branch. We just use this branch to publish to GitHub pages. Run the commands

cd _gh-pages
git rm -rf *
git commit -a -m "flush documentation"
cd ..

The last cd command should put you back at the top level of your PyCBC source directory. To build the documentation into the _gh-pages directory, run the command

python build_gh_pages

This will build the documentation in the second repository that you created called _gh-pages under the directory latest/. To push these changes up to Git Hub

cd _gh-pages
git add --all
git commit -a -m "documentation update"
git push origin gh-pages

The documentation will then be available under your Git Hub pages at where you should replace username/ with your Git Hub account name.

In this example, we checkout the master branch to build the documentation, but you can change the last command above to checkout any other branch that your are developing.


Be careful with the git rm -rf * command as if you run it in the wrong directory you can delete the contents of your git repository. If you do this by accident, you can use git reset to undo the commit.
