Consider using dirs-dev instead of putting everything in $HOME/.bloop

[ckipp01]

Lately I've been trying to clean up my $HOME dir and have been noticing that a lot of the Scala ecosystem stick stuff in $HOME. Looking around in Bloop I see that defaultBloopDirectory is $HOME/.bloop.

bloop/bloopgun/src/main/scala/bloop/bloopgun/util/Environment.scala

Line 26 in efc8d62

def defaultBloopDirectory: Path = homeDirectory.resolve(".bloop")

There are probably other places this is set as well, but I wonder if instead it'd be better to rely on something like dirs-dev to handle this more correctly and place these things in the appropriate places instead of polluting the users home directory. I know this might break some stuff so we could also use $HOME/.bloop for a while as a fallback, but default to the correct places via dirs-dev.

Do you think this would be possible, or do you see any issues with this?

I think that makes sense, I doubt there is any real reason why it necessarily is done via .bloop in home directory.

Though the only problem is .bloop/bloop.json which would be harder to find when using dirs-dev

I think it shouldn't be a problem right? Since it's a config file I'd just expect it to look for XDG_CONFIG_HOME/bloop/bloop.json (in Linux anyways).

Maybe not, yeah. So probably not blockers to do that.

Funny enough, I just realized that Bloop actually has everything that is needed to start just utilizing this, but it's not used by everything. You can see this in

bloop/shared/src/main/scala/bloop/io/Paths.scala

Lines 25 to 31 in 931ce1b

	private def createDirFor(filepath: String): AbsolutePath =
	AbsolutePath(Files.createDirectories(NioPaths.get(filepath)))
	final val bloopCacheDir: AbsolutePath = createDirFor(projectDirectories.cacheDir)
	final val bloopDataDir: AbsolutePath = createDirFor(projectDirectories.dataDir)
	final val bloopLogsDir: AbsolutePath = createDirFor(bloopDataDir.resolve("logs").syntax)
	final val bloopConfigDir: AbsolutePath = createDirFor(projectDirectories.configDir)

So for the config stuff mentioned above we literally need to just start using it.

That's pretty typical in the repo, loads of things were done by one person only team, so it's expected that some stuff might be leftover 😓
