So, is it possible to write a gpm-replacement based on libinput ?

Unfortunately it does not seems the libinput API is documented beyond the doxygen output which is not useful, so the answer is probably no.

what documentation do you need beyond the API docs?

To start with, a minimal example of a program using the library.

The problem is that the documentation just lists functions without the relationship between them.

in the libinput repo there are tools/event-debug.c (commandline tool) and tools/event-gui.c. (a GTK debug tool). Plus there's the xf86-input-libinput X.Org driver which is an example of using libinput inside a device management system that has other approaches than libinput (device discovery and fd handling is a bit weird and overly complicated). With those three you should be able to get started.

tools/event-debug.c sure is useful but there is no instructions how to compile it in a stand-alone way (i.e. outside the libinput directory).

I means, I think I will manage, but it really feel like it was intended that only libinput developers would write libinput programs.

libinput provides a pkgconfig file which is pretty standard for libraries these days. If you don't use that, you'll have to assemble the makeflags/includes yourself but even that shouldn't be much of an issue.

True, but this is not sufficient to compile tools/event-debug.c, so it does not serve as an example file.

I've pushed updated basic documentation to the frontpage of:
https://wayland.freedesktop.org/libinput/doc/latest/index...

Excellent!
If you want an example of proper library documentation I suggest this one
<http://gegl.org/> from a recent LWN item.

thanks, I'll have a look.

note that libinput is a bit special, it's not a generic library that we expect applications to use. there is a very limited number of expected libinput users (most Wayland compositors and the xorg driver) and a few others like research projects and PoCs. but compared to gegl it's not a generic user-facing library, so the documentation requirements are a bit different (i.e. we can ignore most of the entry-level stuff)

Yes I managed! Release 0.0.0 of my project is at <https://alioth.debian.org/projects/consolation/>.
Thanks for your encouragement!
Outside the doc issues, libinput is great!
