Configuration

The default configuration is sufficient to get Zola running locally but not more than that. It follows the philosophy of paying for only what you need, almost everything is turned off by default.

To change the configuration, edit the config.toml file. If you are not familiar with TOML, have a look at the TOML spec.

⚠️ If you add keys to your config.toml, you must pay attention to which TOML section it belongs to. A TOML section starts with a header, e.g. [search], and ends at the next section or EOF.

Here are the current config.toml sections:

  1. main (unnamed)
  2. markdown
  3. link_checker
  4. slugify
  5. search
  6. translations
  7. languages
  8. extra

Only the base_url variable is mandatory. Everything else is optional. All configuration variables used by Zola as well as their default values are listed below:

# The base URL of the site; the only required configuration variable.
base_url = "mywebsite.com"

# The site title and description; used in feeds by default.
title = ""
description = ""

# The default language; used in feeds.
default_language = "en"

# The site theme to use.
theme = ""

# For overriding the default output directory `public`, set it to another value (e.g.: "docs")
output_dir = "public"

# When set to "true", the Sass files in the `sass` directory in the site root are compiled.
# Sass files in theme directories are always compiled.
compile_sass = false

# When set to "true", the generated HTML files are minified.
minify_html = false

# A list of glob patterns specifying asset files to ignore when the content
# directory is processed. Defaults to none, which means that all asset files are
# copied over to the `public` directory.
# Example:
#     ignored_content = ["*.{graphml,xlsx}", "temp.*"]
ignored_content = []

# When set to "true", a feed is automatically generated.
generate_feed = false

# The filename to use for the feed. Used as the template filename, too.
# Defaults to "atom.xml", which has a built-in template that renders an Atom 1.0 feed.
# There is also a built-in template "rss.xml" that renders an RSS 2.0 feed.
feed_filename = "atom.xml"

# The number of articles to include in the feed. All items are included if
# this limit is not set (the default).
# feed_limit = 20

# When set to "true", files in the `static` directory are hard-linked. Useful for large
# static files. Note that for this to work, both `static` and the
# output directory need to be on the same filesystem. Note that the theme's `static`
# files are always copied, regardless of this setting.
hard_link_static = false

# The taxonomies to be rendered for the site and their configuration of the default languages
# Example:
#     taxonomies = [
#       {name = "tags", feed = true}, # each tag will have its own feed
#       {name = "tags"}, # you can have taxonomies with the same name in multiple languages
#       {name = "categories", paginate_by = 5},  # 5 items per page for a term
#       {name = "authors"}, # Basic definition: no feed or pagination
#     ]
#
taxonomies = []

# When set to "true", a search index is built from the pages and section
# content for `default_language`.
build_search_index = false

# Configuration of the Markdown rendering
[markdown]
# When set to "true", all code blocks are highlighted.
highlight_code = false

# A list of directories used to search for additional `.sublime-syntax` files.
extra_syntaxes = []

# The theme to use for code highlighting.
# See below for list of allowed values.
highlight_theme = "base16-ocean-dark"

# When set to "true", emoji aliases translated to their corresponding
# Unicode emoji equivalent in the rendered Markdown files. (e.g.: :smile: => 😄)
render_emoji = false

# Whether external links are to be opened in a new tab
# If this is true, a `rel="noopener"` will always automatically be added for security reasons
external_links_target_blank = false

# Whether to set rel="nofollow" for all external links
external_links_no_follow = false

# Whether to set rel="noreferrer" for all external links
external_links_no_referrer = false

# Whether smart punctuation is enabled (changing quotes, dashes, dots in their typographic form)
# For example, `...` into `…`, `"quote"` into `“curly”` etc
smart_punctuation = false

# Configuration of the link checker.
[link_checker]
# Skip link checking for external URLs that start with these prefixes
skip_prefixes = [
    "http://[2001:db8::]/",
]

# Skip anchor checking for external URLs that start with these prefixes
skip_anchor_prefixes = [
    "https://caniuse.com/",
]

# Various slugification strategies, see below for details
# Defaults to everything being a slug
[slugify]
paths = "on"
taxonomies = "on"
anchors = "on"

[search]
# Whether to include the title of the page/section in the index
include_title = true
# Whether to include the description of the page/section in the index
include_description = false
# Whether to include the path of the page/section in the index
include_path = false
# Whether to include the rendered content of the page/section in the index
include_content = true
# At which character to truncate the content to. Useful if you have a lot of pages and the index would
# become too big to load on the site. Defaults to not being set.
# truncate_content_length = 100

# Optional translation object for the default language
# Example:
#     default_language = "fr"
#
#     [translations]
#     title = "Un titre"
#
[translations]

# Additional languages definition
# You can define language specific config values and translations: 
# title, description, generate_feed, feed_filename, taxonomies, build_search_index
# as well as its own search configuration and translations (see above for details on those)
[languages]
# For example
# [languages.fr]
# title = "Mon blog"
# generate_feed = true
# taxonomies = [
#    {name = "auteurs"},
#    {name = "tags"},
# ]
# build_search_index = false

# You can put any kind of data here. The data
# will be accessible in all templates
# Example:
#     [extra]
#     author = "Famous author"
#
# author value will be available using {{ config.extra.author }} in templates
#
[extra]

🔗Syntax highlighting

Zola currently has the following highlight themes available:

Zola uses the Sublime Text themes, making it very easy to add more. If you want a theme not listed above, please open an issue or a pull request on the Zola repo.

🔗Slugification strategies

By default, Zola will turn every path, taxonomies and anchors to a slug, an ASCII representation with no special characters. You can however change that strategy for each kind of item, if you want UTF-8 characters in your URLs for example. There are 3 strategies:

  • on: the default one, everything is turned into a slug
  • safe: characters that cannot exist in files on Windows (<>:"/\|?*) or Unix (/) are removed, everything else stays
  • off: nothing is changed, your site might not build on some OS and/or break various URL parsers

Since there are no filename issues with anchors, the safe and off strategies are identical in their case: the only change is space being replaced by _ since a space is not valid in an anchor.

Note that if you are using a strategy other than the default, you will have to manually escape whitespace and Markdown tokens to be able to link to your pages. For example an internal link to a file named some space.md will need to be written like some%20space.md in your Markdown files.
