xidlehook: add module

[dschrempf]

Hi!

I am really enjoying the experience with Home Manager so far, thank you!

We could think about replacing xautlock together with caffeine-ng with xidlehook, see https://gitlab.com/jD91mZM2/xidlehook.(Or adding the xidlehook service instead of replacing). What do you think?

Well, I actually had a similar idea, so I would say go on.

I just don't know how to proceed here. Would it better substitute the services.screen-locker to use xidlehook + caffeine-ng, or would be better to have something like some way to handle both in configuration (I think this can possible make the module rather convoluted and confusing).

@rycee, have some opinion here 🤔 ?

I use xidlehook and caffeine-ng in my configuration and have an xidlehook module that is mostly ready to be committed (descriptions lack a final period and there might be more options to add).

I am using the mentioned xidlehook module for some time now and it works very well, thank you. I suggest merging it into the screen-lock module so that either xautolock or xidlehook can be used. The reason for the suggested merge is that "lock on suspend" is only possible using the combination with xss-lock which is already used therein. Of course, xidlehook could also be used for other stuff, so maybe this suggestion is not so well thought through.

[dschrempf]

I think this is still valid. I am still using the mentioned module. I will see if i find time to prepare a pull request (would that be adequate?).

[rycee]

Unfortunately I don't know anything about any of these applications so I have no particular opinion. Ideally I guess it would be nice to have as simple setup as possible, i.e., to use one program or the other and not attempt to support both.

@dschrempf please do

[dschrempf]

This module has been created by @berbiche and (slightly) modified by @dschrempf. This is stated in the preamble, but let me know if you want a more detailed statement of who authored what.

Also, @berbiche, please let me know if you want to be added as a maintainer.

I am using this module for half a year without problems. However, I do not use the advanced features such as cancellers or delays.

[berbiche]

Thanks for the PR.

I don't use X11 anymore since I now have a decent screensharing experience on Wayland; therefore, I wouldn't be able to discover bugs in the module.

Could you add a news entry to news.nix?

[berbiche]

Sorry, I missed one thing.

@dschrempf looks like you need to run the formatter against the code! ./format
