This page explains how you can configure the output of GitBuilding. Most of the customisation is done by putting information in a YAML file called buildconf.yaml. You can also customise the HTML output from GitBuilding by editing the buildconf.yaml file and adding files to the assets directory.

Table of contents

It is recommended to add following keys to the buildconf.yaml to add important information:

  • Authors: Either a list of authors or the name of the author
  • Affiliation: A group the project is affiliated with
  • License: The licence that the project is released under. If this is SPDX license identifier that GitBuilding supports, the licence file will automatically be included. If not you should include a copy of the license file in your documentation folder.
  • LicenseFile: If the license specified is not a recognised SPDX license identifier then this should be a relative link to the license file in your documentation folder.
  • Email: Contact email address

Categories and parts

The buildconf.yaml file can be used to customise the categories for parts in your project.

As standard there are two categories: Part and Tool. The main difference is how the are counted. Parts are added, whereas for tools the maximum number used in any step is recorded. The logic for this is that if you need 1 M3 nut and a 5.5 mm nut driver in one step, and 1 M3 nut and a 5.5 mm nut driver in a later step, then you will need two M3 nuts but only one 5.5 mm nut driver. To set these addition rules Part has a Reuse property set to False, Tool has a reuse property set to True.

Categories also have a DisplayName. When you set the category in a part link you use its name (Part or Tool), but when it is displayed in a bill of materials the display name is used (“Parts” and “Tools”).

An example custom category might be:

        Reuse: True
        DisplayName: Printed tools

As default anything with a category not explicitly stated is assumed to be a Part. The default category can be changed with:

DefaultCategory: PrintedTool

Custom navigation

Note custom navigation will probably update soon

Currently you cannot override the auto-generated navigation, but you can prepend it wil extra links. These links can also be nested. The syntax to do this is:

  - Link: relative_url_1
    Title: LinkName1
  - Link: relative_url_2
    Title: LinkName2
      - Link: sublink_url
        Title: SubLinkName

Customising HTML output

When you run gitbuilding serve or gitbuilding build-html GitBuilding will generate an HTML website for your documentation. This output can be customised as follows:

The header and footer are est using jinja2 templates. If you make a directory in your documentation called _templates and put in files called header.html.jinja or footer.html.jinja it will use these instead of the default ones. This feature is not well documented but you can look at the standard templates for inspiration (in theory any of these could be modified by adding a modified copy to _templates), there is also an example custom header and footer in the example project.

When making custom templates the following variables can be accessed:

  • title - Project title
  • year - The current year
  • root - The website root (see below)
  • authors - Authors of the project
  • email - Contact email for the project
  • affiliation - Project affiliation
  • license - Project licence, will link to the licence if recognised.

Custom variables can be used by specifying them in the buildconf.yaml file as follows:

    version: v6.2
    CustomFooter: >
        <p class="version">The current version of this project is {version}</p>

The footer would be modified to

<p class="version">The current version of this project is v6.2</p>

Custom CSS and favicon

GitBuilding scans for a directory called assets in the root directory. If this directory exists and css files inside it are included in the <head> of the HTML. These style sheets can then be used to override the default CSS of GitBuilding.

The assets directory is also scanned for a favicon.ico file or any PNG favicon which specifies its size (i.e. favicon-16x16.png). If any files are matched they are used as the favicon for the documentation instead of the GitBuilding favicon.

The PNG favicon will only be found if it matches the following regular expression:

Other config options

Other options for the buildconf.yaml file:

  • LandingPage: Specifies which markdown file should become index.html in and HTML build. Not needed if one file is called
  • WebsiteRoot: Sets the root domain for links in the static HTML website that can be built with gitbuilding build-html Default: ‘/’
  • PageBOMTitle: Sets a message to be displayed above the bill of materials on a page when the syntax {{BOM}} is used.
  • Exclude: List of files that are in the documentation directory that you do not want to be processed. (Note: all files beginning with a . or a _ are also excluded. Default: []
  • ForceOutput: This is a list of file that are forced to be in the output. As standard non-markdown files are only included in the output if they are linked to in a BuildUp file. Default is an empty list
  • Title: Can be used to override the title of the project for the HTML build. Default is the title of or the LandingPage
  • Fussy: Boolean value. If true GitBuilding will warn about possible problems with the documentation. Default: True
