irrational: a Sphinx theme

What is irrational?

irrational is a visually (c)lean, responsive, configurable theme for the Sphinx documentation system. It is Python 2+3 compatible.

It began as a third-party theme for https://lab.errorist.xyz projects.

Live example of this theme can be seen on overdub project.

A changelog can be found at the bottom of this page.

Features

Specifically, as compared to Kenneth's theme:

  • Easy ability to install/use as a Python package (tip o' the hat to Dave & Eric's sphinx_rtd_theme for showing the way);
  • Style tweaks, such as better code-block alignment, Github button placement, page source link moved to footer, improved (optional) related-items sidebar item, etc;
  • Many customization hooks, including toggle of various sidebar & footer components; header/link/etc color control; etc;
  • Improved documentation for all customizations (pre-existing & new).

Installation

The bare minimum required to install is as follows:

  1. pip install irrational (or equivalent).

  2. Enable the 'irrational' theme, mini-extension, and sidebar templates in your conf.py:

    import irrational

html_theme_path = [irrational.get_path()]
extensions = ['irrational']
html_theme = 'irrational'
html_sidebars = {
    '**': [
        'about.html',
        'navigation.html',
        'relations.html',
        'searchbox.html',
        'donate.html',
    ]
}

That's it! You now have the standard irrational theme set up. Read on for more configuration options/concerns.

Theme location

The function irrational.get_path dynamically returns irrational's install location, ensuring that Sphinx can find and load it regardless of where/how you installed irrational. Using it is highly recommended.

If you've manually installed irrational and/or are doing funky things to your PYTHONPATH, you may need to replace the irrational.get_path() call with your own explicit string, as per the Sphinx config docs.

Sidebars

Feel free to adjust html_sidebars as desired - the theme is designed assuming you'll always have about.html activated, but otherwise it doesn't care much.

  • See the Sphinx docs for details on how this setting behaves.
  • irrational provides about.html (logo, github button + blurb), donate.html (Gratipay blurb/button) and navigation.html (a more flexible version of the builtin localtoc/globaltoc templates). searchbox.html comes with Sphinx itself.

Images

If you're using either of the image-related options outlined below (logo or touch-icon), you'll also want to tell Sphinx where to get your images from. If so, add a line like this (changing the path if necessary; see the Sphinx docs for 'html_static_path'):

html_static_path = ['_static']

Theme options

irrational's primary configuration route is the html_theme_options variable, set in conf.py alongside the rest. A brief example (note: snippet doesn't include all possible options, see following list!):

html_theme_options = {
    'logo': 'logo.png',
    'github_user': 'bitprophet',
    'github_repo': 'irrational',
}

Variables and feature toggles

  • logo: Relative path (from $PROJECT/_static/) to a logo image, which will appear in the upper left corner above the name of the project.

    • If logo is not set, your project name setting (from the top level Sphinx config) will be used in a text header instead. This preserves a link back to your homepage from inner doc pages.

  • logo_name: Set to true to insert your site's project name under the logo image as text. Useful if your logo doesn't include the project name itself. Defaults to false.

  • logo_text_align: Which CSS text-align value to use for logo text (if there is any.)

  • body_text_align: Which CSS text-align value to use for body text (if there is any.)

  • description: Text blurb about your project, to appear under the logo.

  • description_font_style: Which CSS font-style to use for description text. Defaults to normal.

  • github_user, github_repo: Used by github_button and github_banner (see below); does nothing if both of those are set to false.

  • github_button: true or false (default: true) - whether to link to your Github.

    • If true, requires that you set github_user and github_repo.

    • See also these other related options, which behave as described in Github Buttons' README:

      • github_type: Defaults to watch.
      • github_count: Defaults to true.

  • github_banner: true or false (default: false) - whether to apply a 'Fork me on Github' banner in the top right corner of the page.

    • If true, requires that you set github_user and github_repo.
    • May also submit a string file path (as with logo, relative to $PROJECT/_static/) to be used as the banner image instead of the default.

  • travis_button: true, false or a Github-style "account/repo" string - used to display a Travis-CI build status button in the sidebar. If true, uses your github_(user|repo) settings; defaults to false.

  • codecov_button: true, false or a Github-style "account/repo" string - used to display a Codecov build status button in the sidebar. If true, uses your github_(user|repo) settings; defaults to false.

  • gratipay_user: Set to your Gratipay username if you want a Gratipay 'Donate' section in your sidebar.

    • This used to be gittip_user before that service changed its name to Gratipay; we've left the old setting in place as an alias for backwards compatibility reasons. It may be removed in the future.
    • If both options are given, gratipay_user wins.

  • analytics_id: Set to your Google Analytics ID (e.g. UA-#######-##) to enable tracking.

  • touch_icon: Path to an image (as with logo, relative to $PROJECT/_static/) to be used for an iOS application icon, for when pages are saved to an iOS device's home screen via Safari.

  • extra_nav_links: Dictionary mapping link names to link targets; these will be added in a UL below the main sidebar navigation (provided you've enabled navigation.html.) Useful for static links outside your Sphinx doctree.

  • sidebar_includehidden: Boolean determining whether the TOC sidebar should include hidden Sphinx toctree elements. Defaults to true so you can use :hidden: in your index page's root toctree & avoid having 2x copies of your navigation on your landing page.

  • show_powered_by: Boolean controlling display of the Powered by Sphinx N.N.N. & irrational M.M.M section of the footer. When true, is displayed next to the copyright information; when false, is hidden.

  • show_related: Boolean controlling whether the 'next/previous/related' secondary navigation elements are hidden or displayed. Defaults to false since on many sites these elements are superfluous.

  • page_width: CSS width specifier controlling default content/page width. Defaults to 940px.

  • sidebar_width: CSS width specifier controlling default sidebar width. Defaults to 220px.

Style colors

These should be fully qualified CSS color specifiers such as #004B6B or #444. The first few items in the list are "global" colors used as defaults for many of the others; update these to make sweeping changes to the colorscheme. The more granular settings can be used to override as needed.

  • gray_1: Dark gray.
  • gray_2: Light gray.
  • gray_3: Medium gray.
  • pink_1: Light pink.
  • pink_2: Medium pink.
  • body_text: Main content text.

  • link: Non-hovered body links.
  • link_hover: Body links, hovered.
  • sidebar_header: Sidebar headers. Defaults to gray_1.
  • sidebar_text: Sidebar paragraph text.
  • sidebar_link: Sidebar links (there is no hover variant.) Applies to both header & text links. Defaults to gray_1.
  • sidebar_link_underscore: Sidebar links' underline (technically a bottom-border).
  • sidebar_search_button: Background color of the search field's 'Go' button.
  • sidebar_list: Foreground color of sidebar list bullets & unlinked text.
  • sidebar_hr: Color of sidebar horizontal rule dividers. Defaults to gray_3.
  • anchor: Foreground color of section anchor links (the 'paragraph' symbol that shows up when you mouseover page section headers.)
  • anchor_hover_fg: Foreground color of section anchor links (as above) when moused over. Defaults to gray_1.
  • anchor_hover_bg: Background color of above.
  • note_bg: Background of .. note:: blocks. Defaults to gray_2.

Project background

irrational is a modified version of Jeff Forcier's "Alabaster" Sphinx theme, based on a modified (with permission) version of Kenneth Reitz's "krTheme" Sphinx theme (it's the one used in his Requests project). Kenneth's theme was itself originally based on Armin Ronacher's Flask theme. Many thanks to both for their hard work.
