Before I get into the details, I’m going to say on what I run jekyll locally and then how I made small powershell script to manage my posts. Well, actually I wanted to handle the YML header generation.

My setup

I’ve got a computer running a 64-bit version of Windows 8.1. Nothing fancy, I just re-installed a few days back — the whole update fiasco, kinda ruined my PC. I’ve installed the jekyll prerequisites following this guide:

Then I installed the github-pages gem from GitHub. That’s pretty much everything I did for jekyll. Again nothing fancy.

A little of Twitter Bootstrap, a bit of Bootswatch Cosmo and I have the current setup. It’s not much, but I managed to finish it in a couple of days. The interesting part was to try and also integrate a CI (continuous-integration) server. I’ve made a account a few months back. I trying to make a CI for an old ASP.NET app I was working on. Turns out it didn’t accept .NET projects.

Setting up the CI environment

Setting up the environment is pretty easy. Once you’ve made your project on GitHub, head over to and login with your GitHub credentials.

From there, create a new project:

A new project from

Select your repository.

Use the following Setup Commands:

rvm use 2.1.0 --install
bundle install
bundle update
export RAILS_ENV=test

Use the following Test Commands

bundle exec jekyll build

NOTE: Always make sure you have a gemfile in your repository. Otherwise the bundle install bundle update commands won’t work!

Once you’ve setup your project in Codeship, you’re done with it, because it automatically pushes into the commit status api of GitHub. This looks something like this:

A list of builds from commits into a merge request

As you can see, I’ve had only one build failed. It automatically links back to where you can view what went wrong.

The build log for commit ed06c61 is:

Notice: for 10x faster LSI support, please install
Configuration file: /home/rof/src/
Source: /home/rof/src/
Destination: /home/rof/src/
Error reading file /home/rof/src/ invalid byte sequence in UTF-8
  Liquid Exception: invalid byte sequence in UTF-8 in _posts/
jekyll 2.2.0 | Error:  invalid byte sequence in UTF-8

Apparently when I was testing out my new post generator I forgot to UTF-8 encode the output. That caused some issues, but nothing too big.

Powershell to the rescue

When using jekyll, each post must have YAML Front Matter. It’s a sort of header that tells jekyll some basic information like title, date-posted, categories, tags (or any other information you want to embed into your post). The fact that I need to give filename, having to manually write the Front Matter was a bit of pain — granted, I have a few posts, for now, but I knew it would turn out to be a pain later on.

So I put my developer hardhat on and started figuring something out.

Knowing C# I thought that a simple Console app with a few arguments would do the trick. Making it was pretty easy. In a few minutes I’ve got a working prototype, but then I thought:

Man, it would be easier if I could commit it and push without having to type a git commands or opening a GUI git client.

Robert Iagar in The Heat of August

So then I wanted to add git powers to the app. Enter libgit2sharp. Yes, C# classes for git. What can a dev ask for more?

Apparently I’ve thrown that idea of the window the minute I’ve read an article on how to make git cool in powershell using posh-git. The article was from GitHub's staff Phil Haack himself. That’s how I’ve discovered powershell and the utility is has to offer.

I’ve started to work on a small module.

Post commit workflow

I’ve made a small workflow on how I commit new posts to my blog. To keep everything isolated, I keep every new post on a separate branch, and to use the power of on the first draft I create a pull request, so I can view the progress.

When all is set and done, I merge and close the pull request and my website refreshes. It’s pretty awesome if you think about it.

Now surely there are better ways out there. I’m not sure how people that use jekyll manage their posts or organize their branches or commits, but this is a workflow that I find to work.

If you have any other thoughts, leave a comment.
