Gutenberg uses the [Tera](tera.netlify.com) template engine.
|
|
This documentation will only touch how templates work in Gutenberg, please read
|
|
the [Tera template documentation](https://tera.netlify.com/docs/templates/) if you want
|
|
to know how write them. If you are familiar with Jinja2, Liquid or Twig, this should be
|
|
a breeze.
|
|
|
|
All templates live in the `templates` directory and built-in or themes templates can
|
|
be overriden by creating a template with same name in the correct path. For example,
|
|
you can override the RSS template by creating a `templates/rss.xml` file.
|
|
|
|
If you are not sure what is available in a template, you can just stick `{{ __tera_context }}` in it
|
|
to print the whole context.
|
|
|
|
A few variables are available on all templates except for RSS/Sitemap:
|
|
|
|
- `config`: the [configuration](./documentation/getting-started/configuration.md) without any modifications
|
|
- `current_path`: the path (full URL without the `base_url`) of the current page
|
|
- `current_url`: the full URL for that page
|
|
|
|
## Built-in filters
|
|
Gutenberg adds a few filters, in addition of the ones already present in Tera.
|
|
|
|
### markdown
|
|
Converts the given variable to HTML using Markdown. This doesn't apply any of the
|
|
features that Gutenberg adds to Markdown: internal links, shortcodes etc won't work.
|
|
|
|
### base64_encode
|
|
Encode the variable to base64.
|
|
|
|
### base64_decode
|
|
Decode the variable from base64.
|
|
|
|
|
|
## Built-in global functions
|
|
Gutenberg adds a few global functions to Tera in order to make it easier to develop complex sites.
|
|
|
|
### `get_page`
|
|
Takes a path to a `.md` file and returns the associated page
|
|
|
|
```jinja2
|
|
{% set page = get_page(path="blog/page2.md") %}
|
|
```
|
|
|
|
### `get_section`
|
|
Takes a path to a `_index.md` file and returns the associated section
|
|
|
|
```jinja2
|
|
{% set section = get_page(path="blog/_index.md") %}
|
|
```
|
|
|
|
###` get_url`
|
|
Gets the permalink for the given path.
|
|
If the path starts with `./`, it will be understood as an internal
|
|
link like the ones used in markdown.
|
|
|
|
```jinja2
|
|
{% set url = get_url(path="./blog/_index.md") %}
|
|
```
|
|
|
|
This can also be used to get the permalinks for static assets for example if
|
|
we want to link to the file that is located at `static/css/app.css`:
|
|
|
|
```jinja2
|
|
{{ get_url(path="css/app.css") }}
|
|
```
|
|
|
|
In the case of non-internal links, you can also add a cachebust of the format `?t=1290192` at the end of a URL
|
|
by passing `cachebust=true` to the `get_url` function.
