The command line tool
doc-checker performs several checks on the documentation
source. Checks that do not need to access external links are performed as
presubmit checks when submitting changes to the //docs directory.
The primary goal of doc-checker is to make sure all the documents in the
directory are part of the interconnected graph made up of
_toc.yaml files and in-page
links are reachable when the documentation is published on
fuchsia.dev. Other checks inspect the links themselves to enforce documentation
standards and consistency.
The external link check can be skipped by adding

These are the situations that are reported by doc-checker:
Internal link checks
Links to nonexistent files
Links to files in //docs represented as full URLs
These are links that reference
access a file in //docs. These links should be converted to file paths.
Links to inactive Fuchsia projects
These are projects that are included in the Fuchsia source tree which have been merged into Fuchsia or completed deprecated. The list of valid projects is part of the source code.
[invalid old project](https://fuchsia.googlesource.com/garnet/+/refs/heads/main)
Links with relative paths past //docs
These are links that point to paths beyond the //docs directory. These should be
fuchsia relative paths.

YAML data file checks
These checks enforce the table of contents structure described in _toc.yaml reference.
- top level key
entries are one of:
break: true- (optional) Adds a vertical break
contents: <list of toc entries>- (optional) The contents of a custom tab.
heading: <string>- (optional) The heading for a group of links.
include: <path to _toc.yaml>- (optional) Includes another _toc.yaml.
name: <string>- (optional) Name of this tab.
path: <string>- (optional) Path or URL to a page.
path_attributes: <mapping>- (optional) Name-value pairs of attributes for the link created based on the
section: <toc entry>- (optional) Indented toc entry defining a collapsible section, usually defined via
includeanother _toc.yaml file.
skip_translation: true- (optional) Prevents human and machine translation of all link titles in this entry and any descendents.
status: <string>- (optional) Used with
titleand cannot be used with
include. Applies a predefined status. The status must be one of:
step_group: <string>- (optional) Used to create groups of content that have
nextnavigation links to the bottom of the pages.
style: <string>- (optional) Cannot be used with
include. This style is applied to the
sectionelement. This value must be
title: string- (optional) The link title.
