The plugin description for a libpeas plugin contains a line determining the Loader
and with this the programming language the plugin is written in. It seems the documentation includes not list of available languages. Inspecting the git repository of the project, a top-level directory "Loaders" can be found listing entries for
- c,
- gjs,
- seed and
- python.
It is unclear also if the python version expected is 2 or 3.
These are by far fewer languages that the related gobject introspection provides support for.
Are the listed 4 all available loaders? Or do external projects exist that provides more loaders?
