Bit Nebula

After looking at how yeoman.io generates their website using Travis CI, I thought I'd give it a try myself. After spending a couple of hours figuring out how all of this stuff works (and making a lot of mistakes¹ in the process), I am pleased to say that this blog is now built by Travis! :D

The process itself is actually quite cool. Travis runs a build (basically whatever it is asked to do in .travis.yml) every time I push something to the master branch of polybuildr/blog.

In the build process, I ask Travis to do this:

#!/bin/bash
set -ev
HASH=$(git rev-parse --short HEAD)
git clone --branch=gh-pages https://github.com/polybuildr/blog.git blog
petroglyph --regenerate
cd blog
if [ -n "$(git status --porcelain)" ]; then
    git config user.name "Travis CI"
    git config user.email travis@travis-ci.org
    git add .
    git commit -m "Built blog from commit $HASH"
    git push --force --quiet https://${GH_TOKEN}@github.com/polybuildr/blog.git > /dev/null 2>&1
else
    echo "No changes to push."
fi

If I see other people using petroglyph for their own blogs, I'll publish a guide to using Travis for deploying a petroglyph blog to GitHub pages, but for now, I don't think that will be of any particular benefit.

For now, I can enjoy the sweet pleasure of simply adding a markdown file to the posts/ directory of polybuildr/petroglyph:master and letting Travis take care of all the hard CI work. :')
