Template engine explanation

Cobalt gets ~ as, while based on Liquid, the Rust library doesn't implement all its features but there is no documentation on what is and isn't implemented. The errors are also cryptic. Liquid itself is not powerful enough to do some of things you can do in Jinja2, Go templates or Tera.

Hugo gets ~. It is probably the most powerful template engine in the list after Jinja2 (hard to beat python code in templates) but personally drives me insane, to the point of writing my own template engine and static site generator. Yes, this is a bit biased.

Pelican notes

Many features of Pelican are coming from plugins, which might be tricky to use because of version mismatch or lacking documentation. Netlify supports Python and Pipenv but you still need to install your dependencies manually.


As the documentation site is automatically built on commits to master, all development should happen on the next branch, unless it is fixing the current documentation.

If you want a feature added or modified, please open an issue to discuss it before doing a PR.

Adding syntax highlighting languages and themes

Adding a syntax

Syntax highlighting depends on submodules so ensure you load them first:

$ git submodule update --init

Gutenberg only works with syntaxes in the .sublime-syntax format. If your syntax is in .tmLanguage format, open it in Sublime Text and convert it to sublime-syntax by clicking on Tools > Developer > New Syntax from ... and put it at the root of sublime_syntaxes.

You can also add a submodule to the repository of the wanted syntax:

$ cd sublime_syntaxes
$ git submodule add https://github.com/elm-community/SublimeElmLanguageSupport

Note that you can also only copy manually the updated syntax definition file but this means Gutenberg won't be able to automatically update it.

You can check for any updates to the current packages by running:

$ git submodule update --remote --merge

And finally from the root of the components/highlighting crate run the following command:

$ cargo run --example generate_sublime synpack ../../sublime_syntaxes ../../sublime_syntaxes/newlines.packdump

Adding a theme

A gallery containing lots of themes is located at https://tmtheme-editor.herokuapp.com/#!/editor/theme/Agola%20Dark. More themes can be easily added to gutenberg, just make a PR with the wanted theme added in the sublime_themes directory and run the following command from the root of the components/rendering:

$ cargo run --example generate_sublime themepack ../../sublime_themes ../../sublime_themes/all.themedump

You should see the list of themes being added.
