Templates

Thermite uses Tera for templating. If you've used Jinja2 or Nunjucks, you already know Tera.

Variables

Every template gets these variables:

Site-level (from thermite.toml)

Variable	Source
`site_title`	`title`
`site_description`	`description`
`base_url`	`base_url`

Plus any [extra] keys, injected by name.

Page-level (from frontmatter + content)

Variable	Description
`title`	Page title
`content`	Rendered HTML — use `{{ content \| safe }}`
`content_raw`	Original Markdown source
`date`	Display date (no time component)
`date_raw`	Original date string from frontmatter
`description`	Page description
`tags`	Tag array
`url`	Page URL path
`og_image`	Page or site-level OG image
`og_type`	`"article"` for dated non-index, `"website"` otherwise
`canonical_url`	`base_url` + `url`

Page list

Variable	Description
`pages`	Array of other pages (dated, non-index only)

Each entry: title, date, date_raw, url, description.

Note: pages only includes pages with a date that aren't index.md. Undated pages still build — they just don't appear in the list.

Example

A minimal base.html:

<!DOCTYPE html>
<html>
<head>
    <title>{{ "{% block title %}" }}{{ site_title }}{{ "{% endblock %}" }}</title>
</head>
<body>
    {{ "{% block content %}{% endblock %}" }}
</body>
</html>

A page.html extending it:

{{ "{% extends \"base.html\" %}" }}
{{ "{% block title %}" }}{{ "{{ title }}" }} — {{ "{{ site_title }}" }}{{ "{% endblock %}" }}
{{ "{% block content %}" }}
<h1>{{ "{{ title }}" }}</h1>
{{ "{{ content | safe }}" }}
{{ "{% endblock %}" }}

Markdown

Thermite uses pulldown-cmark with these extensions:

Tables — pipe syntax
Footnotes — [^1] references
~~Strikethrough~~ — double tildes
Task lists — - [ ] and - [x]
Heading attributes — # Title {#custom-id}

Standard Markdown (links, images, code blocks, blockquotes, lists) works as expected.
