Checking link texts

A reference written without a link text of its own shows the title of its target. The documentation guidelines ask for a text of its own instead, see Link text. A manual can have the rendering warn about every reference that has none:

Documentation/guides.xml

<extension class="\T3Docs\Typo3DocsTheme\DependencyInjection\Typo3DocsThemeExtension"
           interlink-shortcode="my-manual"
           check-link-text="true"
/>

The check is off by default. Most manuals still have references without a link text, and a warning fails a render with --minimal-test, which is what their pipelines run.

What is checked

:ref: and :doc:: Warns about :ref:my-label and :rst:`:doc:`Some/Page, but not about :ref:Link text <my-label>``.
Permalinks: Warns about a permalink URL written on its own, such as https://docs.typo3.org/permalink/my-manual:my-label, since it too shows the title of its target.

Not checked are the roles that show the name they point to, such as :php:, :confval:, or :t3ext:, and the :changelog: option of versionchanged and its kind, which shows the title of the Changelog entry by design.

The warning names the file, but not the line, since a reference does not record where it was written.

Switching the check per page

A page can override the manual's setting with a field at its top, before the title. This switches the check off for a page that shows a reference without a link text on purpose:

Documentation/Menus/NavigationTitle.rst

:check-link-text: off

================
Navigation title
================

:check-link-text: on works the other way, for a manual that is being cleaned up page by page while the manual's setting is still off.
