  • Playing with git hooks

    Git scm offers a very interesting technique, called hooks. A hook is basically a trigger which is fired after the specific event occurs. If you create a new git repository with git init the folder .git/hooks with a couple of sample shell scripts is created. I personally use a hook to automate the deployment process of this website. After a commit is made, I automatically run a jekyll build and then copy the newly created site to the server. My current post-commit script looks like the following, simple but effective:

    jekyll build
    scp -r _site/* user@host:/home/user/html/
    ##Update 2015-12-11 I slightly changed the deploy script to only update changed files because I realized that the time to update the homepage will increase with every posting. For this reason I had to use rsync. Now the scripts looks as follows:
    jekyll build
    rsync --update --progress -r _site/* user@host:/home/user/html/
    The easiest way to synchronize over SSH is with a certificate.

  • First experiments with Jekyll

    Today, I’m trying out how to build this website with jekyll. With jekyll one can easily write markdown and yml files and create static pages from it. The advantages are obvious. No problems with scripts and security issues since all the files are HTML5, CSS and only a bit of Javascript. Also there is no need for complex server configuration or any high server speed. A simple webspace with FTP or SSH access is enough.
