whoops, i didn't mean to request a merge for this yet, since it's a bit bundled together and out of order. was too quick on running github-cli while preparing it

i initially started working on adding support for pidfile because that makes service managers happy, and one thing led to another lol.

while i haven't changed any implementation behaviour, this PR is a breaking change. commands are no longer flags, for instance. i believe i have documented all the new things, though. if i missed something, please let me know.

i realize this PR would be best split into two different PRs, sorry about that. let me know if something should be changed :)

changes:

• there is no longer a monolithic amdfan.py file, but rather a main module accessible through __main__.py or -m amdfan

• core functionality is now split into subcommands, instead of exclusively relying on flags

• distribution files like services and package builds are now under dist/. they are no longer copy and paste, and require the use of autotools (or sed). this should make it easier to adapt for niche users

• documentation is now split into README and INSTALL, since end-users should really be using their package manager instead of manually installing system packages with pip

• the daemon now writes a pidfile upon launch

• the daemon now supports reloading config through a SIGHUP signal, without restarting the service entirely

• we can now specify a ready notification file descriptor to be used

i think it would be wise to update and aggregate to the tests too. i only updated the tests which already existed

Cool I'll take a look, sorry was out on vacation this week, so haven't kept up with GH.

Suggested change

	The executable files are contained within amdfan. This directory is a python module, and can either be loaded as `python -m amdgpu`. If you want to import the module, you may be interested in checking out `amdfan.commands`, which contains most of the subcommands.

Looks good, I'll have to pull it down to make sure I can still build it for the Arch packaging, and to make sure it still works with my py3status-amdfan, I'll likely just have to modify some of the commands on the widget side of things.

Oh, lovely, thanks for merging it. :)

Sorry about the delay myself, I have been AFK too. Is there anything left to do/change? I know the tests should probably be updated... but that's probably for another time.

It seems you got the PKGBUILD covered? If you think it's ready, I will bump the ebuild for Gentoo on ::guru too.

yeah I fixed at least the existing tests, so that the right cli funcs are passed so we no longer have the 2 == 1 etc.

The rest of the changes were just to make it work with the github workflow build.
