Parse ~/.config/user-dirs.dirs file about xdg

[mateusz834]

Also it looks like XDG_*_DIR env vars do not override the user-dirs.dirs file, checked in firefox/chromium

const (
	envDesktopDir     = "XDG_DESKTOP_DIR"
	envDownloadDir    = "XDG_DOWNLOAD_DIR"
	envDocumentsDir   = "XDG_DOCUMENTS_DIR"
	envMusicDir       = "XDG_MUSIC_DIR"
	envPicturesDir    = "XDG_PICTURES_DIR"
	envVideosDir      = "XDG_VIDEOS_DIR"
	envTemplatesDir   = "XDG_TEMPLATES_DIR"
	envPublicShareDir = "XDG_PUBLICSHARE_DIR"
)

Hi @mateusz834. Thank you for your interest in the library. Reading user-dirs.dirs is already a task in my to-do list.
I'll start working on this. Hopefully, I can release a new version sometime next week (depending on my free time).

Also it looks like XDG_*_DIR env vars do not override the user-dirs.dirs file, checked in firefox/chromium

Yeah, that seems to be the case. I think the priority to should be:
user-dirs.dirs values > environment variables > defaults

[mateusz834]

It even look like that env vars are completely ignored by firefox/chromium.
I removed the user-dirs.dirs file and set the XDG_DOWNLOAD_DIR env var to a different directory and the downloaded file was saved in the default directory.

But for backwards compatibility I think that the order should be:
environment variables > user-dirs.dirs values > defaults

Maybe someone is relying on the env vars now and after the change it will suddenly use values from user-dirs.dirs??

Ideally, there would be no breaking changes. I try to steer clear of them as much as possible. However, in this case, I think the default behavior going forward should be to rely on the values provided by user-dirs.dirs, then fall back to other sources.

I made a quick search through GitHub and it seems most people are using this package for base directories rather than user directories. I think very few people customize user directory environment variables anyway, especially if they're ignored by other applications. In any case, the change will be documented in the release notes.

Alternatively, I could introduce an option to control whether user-dirs.dirs has priority. However, I think it clutters the package interface unnecessarily.

Any updates on this? I recently found this library and I guess I'm one of the edge cases that need the parsing of user-dirs.dirs.
