Configuration Options

4 minute read Published: 2025-06-01

This page describes the configuration options available for the radion theme.

Table of Contents

Installation

First download this theme to your themes directory:

cd themes
git clone https://github.com/micahkepe/radion

and then enable it in your config.toml:

theme = "radion"

This theme requires your index section (content/_index.md) to be paginated to work:

paginate_by = 5

The posts should therefore be in directly under the content folder.

The theme requires tags and categories taxonomies to be enabled in your config.toml:

taxonomies = [
    # You can enable/disable RSS
    {name = "categories", feed = true},
    {name = "tags", feed = true},
]

If you want to paginate taxonomies pages, you will need to overwrite the templates as it only works for non-paginated taxonomies by default.

Options

Set a field in extra with a key of radion_menu:

radion_menu = [
    {url = "$BASE_URL", name = "Home"},
    {url = "$BASE_URL/categories", name = "Categories"},
    {url = "$BASE_URL/tags", name = "Tags"},
    {url = "https://google.com", name = "Google"},
]

If you put $BASE_URL in a url, it will automatically be replaced by the actual site URL.

Title

The site title is shown on the homepage. As it might be different from the <title> element that the title field in the config represents, you can set the radion_title instead.

Author Attribution

You may define the author(s) of a page in either the root config.toml file, or on a per-page basis in the page's frontmatter.

The order of precedence for determining the author shown in a page’s footer is:

page.extra.author (highest precedence)
page.authors
page.config.author (lowest precedence, default)

Defining a Global Default Author in `config.toml`

In config.toml:

[extra]
author = "John Smith"

Defining Author(s) Per-Page

At the top of a page in its frontmatter (wrap this in +++):

Define a single author for the page:

title = "..."
date = 1970-01-01

[extra]
author = "John Smith"

Alternatively, you can define the page.authors variable with a single entry:

title = "..."
date = 1970-01-01
authors = ["John Smith"]

Define multiple authors for a page:
```
title = "..."
date = 1970-01-01
authors = ["John Smith", "Joe Schmoe", "Jane Doe"]
```
For example, you can see on this page there are multiple authors attributed.

Note

Do not define both extra.author and authors in the same page unless you want extra.author to take precedence.

Favicon

To change the default favicon:

Create your own favicon folder with the following site: RealFaviconGenerator
- Set the 'Favicon path' option to /icons/favicon/
Unzip the created folder
Create a static/icons/ directory if it does not already exist
Place the unzipped favicon/ directory in static/icons/.

By default, favicons are enabled, however, if for some reason you would like to disable favicons, set the following in your config.toml:

[extra]
favicon = false

GitHub

To enable a GitHub reference link in the header, set the following in your config.toml:

[extra]
github = "https://github.com/your-github-link"

Code Snippets

Syntax Highlighting:

[markdown]
# Whether to do syntax highlighting
# Theme can be customized by setting the `highlight_theme` variable to a theme
# supported by Zola
highlight_code = true
highlight_theme = "one-dark"

For a complete list of themes, see: Zola's syntax highlighting docs.

Enhanced Codeblocks (Clipboard Support and Language Tags)

[extra]
codeblock = true

Note: Ligatures

Ligatures are disabled by default as defined in the _theme.scss file.

LaTex Support

To enable LaTeX support with MathJax, set the following in your config.toml:

[extra]
latex = true

Searchbar

To enable a searchbar at the top of the page navigation, set the following in your config.toml:

build_search_index = true

[search]
index_format = "elasticlunr_json"

[extra]
enable_search = true

Light and Dark Modes

To set the color theme of the site, set the following in your config.toml:

[extra]
theme = "toggle" # options: {light, dark, auto, toggle}

There are four options for the theme field:

light: Always light mode
dark: Always dark mode
auto: Automatically switch between light and dark mode based on the user's system preferences
toggle: Allow the user to toggle between light and dark mode

To enable a table of contents on a page, add the following to the front matter of the page:

[extra]
toc = true

Comments

Note: Giscus comments assumes that you are hosting the blog site via GitHub Pages and thus have access to GitHub Discussions.

First, follow the instructions at giscus.app. This includes installing the Giscus app and enabling discussions on the GitHup repository that you host the website code. Additionally, fill in the repository path in the prompt. Then, from the generated script, fill in the corresponding values in the config.toml:

[extra]
comments = true  # {true, false}; sets global enabling of comments by default
giscus_repo = "FILL ME IN"
giscus_repo_id = "FILL ME IN"
giscus_data_category_id = "FILL ME IN"

Comments can be enabled or disabled on a per page basis by editing the page's front matter. For example, to disable comments on a specific post:

[extra]
comments = false

The config.toml value for comments takes precedence and priority. For example, if you globally disable comments in your config.toml by setting comments = false, then trying to enabling comments through a page's front matter will have no effect.
