How To Install gi-docgen on Debian 12
Introduction
In this tutorial we learn how to install gi-docgen on Debian 12.
What is gi-docgen
gi-docgen is:
GI-DocGen is a document generator for GObject-based libraries. GObject is the base type system of the GNOME project. GI-Docgen reuses the introspection data generated by GObject-based libraries to generate the API reference of these libraries, as well as other ancillary documentation.
GI-DocGen is not a general purpose documentation tool for C libraries: while GI-DocGen can be used to generate API references for most GObject/C libraries that expose introspection data, its main goal is to generate the reference for GTK and its immediate dependencies.
GI-DocGen is still in development. The upstream-recommended use of GI-DocGen is to add it as a sub-project to a Meson build system, and vendor it when releasing dist archives. Until GI-DocGen becomes stable, Debian packages that use it for their documentation should use a vendored copy (as allowed by Policy ?4.13), and should not have a Build-Depends on gi-docgen unless no vendored copy is present in upstream releases.
