conversions were done using https://github.com/pennae/nix-doc-munge
using (probably) rev f34e145 running
nix-doc-munge nixos/**/*.nix
nix-doc-munge --import nixos/**/*.nix
the tool ensures that only changes that could affect the generated
manual *but don't* are committed, other changes require manual review
and are discarded.
the conversion procedure is simple:
- find all things that look like options, ie calls to either `mkOption`
or `lib.mkOption` that take an attrset. remember the attrset as the
option
- for all options, find a `description` attribute who's value is not a
call to `mdDoc` or `lib.mdDoc`
- textually convert the entire value of the attribute to MD with a few
simple regexes (the set from mdize-module.sh)
- if the change produced a change in the manual output, discard
- if the change kept the manual unchanged, add some text to the
description to make sure we've actually found an option. if the
manual changes this time, keep the converted description
this procedure converts 80% of nixos options to markdown. around 2000
options remain to be inspected, but most of those fail the "does not
change the manual output check": currently the MD conversion process
does not faithfully convert docbook tags like <code> and <package>, so
any option using such tags will not be converted at all.
This commits deprecates `services.xserver.libinput` for multiple
settings, one for each kind of device:
- `services.xserver.libinput.mouse`
- `services.xserver.libinput.touchpad`
Looking at `man 4 libinput`, they basically have the same options so I
simply replicated them, even if some options doesn't make sense for
mouse (`tapping` for example).
With this commit this is now possible:
```nix
{
services.xserver.libinput = {
enable = true;
mouse = {
accelProfile = "flat";
};
touchpad = {
naturalScrolling = true;
};
};
}
```
And you will have a mouse with no natural scrolling but with accel
profile flat, while touchpad will have natural scrolling but accel
profile adaptative (default).
It is possible to support more device types
(tablets/keyboards/touchscreens), but at least looking at the
libinput manual for those devices it doesn't seem that it has any
configuration options for them. They can still be configured using
`services.xserver.inputClassSections` though, and this will work now
since there is no rule by default that matches them.
Closes issue #75007, while also making configuration of mouses and
touchpads using Nix attrs possible like said in PR #73785.
On numerous occasions I have seen users mistake this
module as libinput because it being called "multitouch"
and them being unaware that the actually module they want
is libinput. They then run into several decrepit bugs due
to the completely out-of-date nature of the underlying package.
The underlying package hasn't been changed to an up-to-date
fork in a period of 8 years. I don't consider this to be production quality.
However, I'm not opposed for the module being readded to NixOS
with new packaging, and a better name.
Instead of assign the libinput options to touchpad devices only, it
should be appied by any device using libinput.
Due to the fact that `40-libinput.conf` already defines libinput as
driver for any detected input device, we can use `MatchDriver` to appy
options.
