Dead-Simple Blogging Platform
June 27, 2014
After hacking on several Wordpress projects, I’m tired of Wordpress. The same can be said of the Grunt.js task-runner. Both systems are simply too complex for the task of displaying words on an Internet page. I now use neither of these tools.
TL;DR: The source for this site is available on Github.
After spending over a year living in the command line with Vim and unix tools, I’ve come to appreciate small, simple, composable components that do one thing well.
I use only a few small and simple tools to power this blog, and it’s the most pleasant development and publishing experience I’ve had. In terms of languages, the development stack is Ruby and a bit of Bash. I use Make as well, but it’s not really a separate language and I use it mostly as a wrapper around my shell scripts.
Hosting & Deployment
I think FTP is lame and old-hat, but I’m also slightly too lazy to setup any kind of git hook that deploys the site whenever I push some changes. Fortunately, Github Pages does all this stuff automatically, and they’re very fast and stable (I’ve even had a few months with absolute zero downtime), and they’re free. Can’t get a better price than free.
For this to work, I created a
jezen.github.io repository and a branch called
source. As the name implies, the
source branch is for the source code and content I actually work with. The
master branch is only for generated files. There are a few steps to making this play nicely with Jekyll:
- Clone the repository to some directory. Let’s call it
- Create a directory inside
blogwhich we use as our build target. Let’s call it
- Clone the repository into the
distdirectory. Yes, we have the repository inside the repository.
- In the
blogdirectory, checkout the
distdirectory should always be on
- Create a
.gitignorefile in the
blogdirectory, and add
distto the file.
destination: distto your
_config.ymlfile, so Jekyll knows where to output generated files.
The final trick is to create an empty file in the
blog directory called
.nojekyll. This file tells Github not to try building the site. Github won’t be able to build the site if you use any custom Jekyll plugins. It’s easy enough to generate the site on your local machine anyway, so why not. Add
include: ['.nojekyll'] to your
_config.yml file so the
.nojekyll file is always included in the generated site.
Deploying to Github is as simple as pushing all the stuff in the
dist directory. I have a shell script called
deploy to handle this, which looks like this:
Don’t forget to do
chmod u+x deploy so the file is actually executable.
Jekyll comes with an ad hoc server, which we can fire up with
jekyll serve. When I’m working, I like to keep a copy of the site open in a browser so I can quickly review changes. I use a couple of flags to tell Jekyll that I want to display draft posts, and I also want the server to rebuild the site whenever a file is changed. In the end, the command is
jekyll serve --drafts --watch.
I do much the same thing with Sass. I use the command
sass --watch _sass/main.sass:main.css to watch the
main.sass file and compile it into
main.css whenever a change is made.
Since I generally only ever use one terminal instance, I make use of some Unix job control to move these two ‘watch’ tasks out of my way. I have a shell script called
serve that sets these tasks up for me, which looks like this:
The parantheses means these jobs run in subshells, so they don’t get in each other’s way.
I mentioned earlier that I use Make. I like Make because it’s a nice wrapper for my shell scripts, and I can also write short scripts in it directly. It seems to be a convention to have a default task in a Makefile that builds everything, but I prefer to use the first task for documentation so I can quickly remind myself how I should manage the site. Let’s take a look at my Makefile:
SHELL := /bin/bash .PHONY: default build serve deploy default: @printf "\n Howdy! Use the following commands to manage this site:\n" @printf " - build \t Build the site for production" @printf " - serve \t Run an ad hoc WEBrick server" @printf " - deploy \t Push the site live to GitHub \n\n" build: jekyll build sass --style compact _sass/main.sass dist/style.css awk 'NF > 0' dist/style.css > tmp && mv tmp dist/style.css serve: ./serve deploy: build ./deploy
Starting from the top, I tell Make which shell to use. If you don’t do this, Make will use
sh by default, which is likely to give some odd surprises at some point.
.PHONY line is needed because all of the task names in the file are just generic names, and don’t reference any real file in the project. If you don’t do this, and you have a file with the same name as one of your tasks, Make will get confused.
My first task is called
default, and it’s run if you do
make from the shell without any arguments. This pattern is used for many other Unix tools, and I’m quite fond of it. Be sure to use
printf and not
echo, because of the two, only the former is portable.
build task builds the site and the styles, and then does some poor-man’s file compression of the output css with
awk. That last step is probably a bit pointless, but it was a nice exercise. The
deploy tasks simply run their respective shell scripts. You’ll notice the
deploy task depends on the
build task, so the latest version of the site is always deployed to Github.
When I want to work on the site, I could just run
make serve, but then the two tasks would print their output to the terminal. I’d rather the output would get out of my way, so I start the task in the background and send its output to a nohup.out file. To do this, run
nohup make serve &.
There’s not much more to it, and nor should there be.
