MooseDocs Configuration

In order to use MooseDocs build command a configuration file is required. By default the script looks for a config.yml file (the --config option can be used if a different name is desired). As the extension suggests, this file is a YAML file. The configuration file must contain a Content section and may optionally contain additional sections, as listed below, to configure your MooseDocs build.


The content section is typically a list of directories that contain the markdown content that is desired to be rendered to HTML, as shown below. It is possible to use environment variables within the list. In particular, MOOSE_DIR and ROOT_DIR are always available, where ROOT_DIR is the directory of your application.

    - doc/content
    - ${MOOSE_DIR}/framework/doc/content

The path may also include * and ** wildcards. The * wildcard will match any single directory or filename. For example, doc/content/*/minimal will include all sub-directories of the content directory that contain a minimal directory. The ** wildcard allows for arbitrary levels of nesting. For example doc/content/**/minimal will include the minimal directory for any directory below the content directory, regardless of depth.

Advanced Content

There is also a more advanced interface for the content, but it is required to explain how these directories are used. When building content all relevant files (e.g., markdown) are extracted from the supplied list of directories into a set, with the path relative to the supplied directory. This unique set of files is then copied to the destination directory of the build, with markdown files being rendered to html first. For example, the following illustrates how the multiple source files are combined in the destination directory.

doc/content/ -> ${HOME}/.local/share/moose/site/index.html
${MOOSE_DIR}/framework/doc/content/utilities/ -> ${HOME}/.local/share/moose/site/utilties/

In the advanced mode the root location can be specified for each location, in this case the content configuration section contains a dictionary of dictionaries as shown below. The top-level key is an arbitrary name, the second level has two keys available: "root_dir" and "content". The root_dir is the directory to include and "content" is a list of folders and/or files within the root_dir to consider.

        root_dir: doc/content
        root_dir: ${MOOSE_DIR}/framework/doc/content/utilities
            - MooseDocs

Given the above configuration, the files within the MooseDocs folder are now included directly within the destination folder (i.e., the "utilities" directory is removed) as shown below.

doc/content/ -> ${HOME}/.local/share/moose/site/index.html
${MOOSE_DIR}/framework/doc/content/utilities/MooseDocs/ -> ${HOME}/.local/share/moose/site/MooseDocs/


The Extensions section is used to enable non-default or custom extensions as well as change the configuration for existing extensions. The list of default extensions is shown in Listing 1. For example, the following snippet changes the settings for the Common Extension extension. Note, the first level key name ("globals") is arbitrary and the "type" key name under that is required. The value matches with the python package loaded, as in Listing 1.

        type: MooseDocs.extensions.common
        shortcuts: !include framework/doc/globals.yml

The various extensions as well as links to the documentation for each extension, which includes the available configuration options, is found on the specification page.

DEFAULT_EXTENSIONS = ['MooseDocs.extensions.core',


The Renderer section allows for the type of renderer to be selected, the default is the MaterializeRenderer. This is the only complete renderer object and it does have many available options, please refer to the source code for the available options. An example Renderer section is shown below.

    type: MooseDocs.base.MaterializeRenderer
    name: MOOSE
    google_analytics: True


The Reader section allows the reader object to be defined, by default the MarkdownReader objects is used. Currently, this is the only type of reader and there are no configuration options, so this section is not necessary.
