Writing a post

See the Jekyll Documentation for how to create a Jekyll post.

Supported YAML Frontmatter fields

Option	Description	Default
`title`	The title of the post
`description`	A brief description of the post. This description may be used by search engines, and will be used when the post is shared on Facebook and Twitter.	`site.description`
`image`	The hero image	`site.hero.image`
`fallback-color`	Hex color code of the color (in quotes) that will be shown behind the hero image. This is especially useful if the hero image fails to load, or takes a while to do so. If we show the image’s average color, the flash of the image appearing will be less harsh. I’ve been using Color Thief to get this average color.	`site.hero.fallback-color`
`comments`	If `false`, there won’t be a Disqus comment field on the post	`true`
`published`	If `false`, the post won’t be rendered or published	`true`
`unlisted`	If `true`, the post will be published, but won’t be listed in the RSS feed or on the front page	`false`
`edited`	If `true`, there will be a link leading to the post’s GitHub edit history at the bottom of the post	`false`
`hn`	If a HN link is specified, there will be a link leading to the HN discussion at the bottom of the post

Excerpt separator

On the front page of the site, excerpts of every post are shown. On this site, a post “breaks” on the first HTML comment by default, so the end of the front page’s excerpt can be marked as such in a post:

Building the site

Development

In a development environment, the following command should suffice:

jekyll serve

Production

In production, we’re not serving the site locally, we’re building it. This is done through the following command:

jekyll build

To prepare the site for production, a few additional steps are taken.

Autoprefixer ensures that all the CSS is compatible with the 2 last versions if every browser
Hero images are resized to the breakpoints defined in _config.yml
Assets are Zopfli-compressed

There’s a grunt task set up that handles the first two:

grunt build

The last one is (for now) a simple bash command to the zopfli binary. It would be great to manage this through Grunt though.

zopfli --i1000 $files

Luckily, this is all done automagically with Travis CI. You can see the scripts it runs in the _scripts folder.

Wishlist / Todo :star:

[ ] Rework _config.yml file to provide more optional switches
[ ] Rework _config.yml‘s prose.io settings
[ ] Rework 404 page
[ ] Set up Grunt to take care of Zopfli compression
