Reduce disk space

[flip111]

My 64GB laptop SSD is getting rather full and i saw that stack takes up a lot of diskspace. I tried putting all my projects on the same LTS version and clear out the snapshot folder. Also i delete a tar.xz file in the programs folder. Is there anything else that can be done?

stack clean --full in your different projects to remove all build files.

NOTE: only do that on >= 1.0.4.3, see #2000

@flip111, in your experience is it safe to delete the ~/.stack/snapshots/x86_64-linux/lts-XXX folder if lts-XXX is a snapshot that I no longer care about?

I tried this once, and it caused me ghc-pkg errors related to missing alex/happy files in the deleted directory later on. (The errors happened when I was building a stack project using a different snapshot.) I had to symlink the files to lts-XXX to fix this.

Actually, it looks like this was discussed at #1847 and #133. I'll just read the discussion there.

Sorry for the noise.

indices is now 1.3G .. perhaps anyone knows a list of directories/files that are safe to remove? Could just store that as a shell script and run that once in a while ...

stack clean --full in your different projects to remove all build files.

Then i have to go into all those projects. But i mainly want to clean out lts versions which i'm no longer using and also tar.xz archives if they are not needed. Why are those tar.xz files kept actually?

104M	build-plan
14M	build-plan-cache
12K	config.yaml
1,5M	global-project
1,3G	indices
26M	loaded-snapshot-cache
22M	precompiled
5,4G	programs
45M	setup-exe-cache
108K	setup-exe-src
3,9G	snapshots
52K	templates

11G total .. it's quite a lot

The binaries in ~/.stack/snapshots/x86_64-linux/*/*/bin also take a lot of space. Are they still needed after being copied to ~/.local/bin ?

What about when running this function

stack/src/Stack/Setup.hs

Lines 938 to 956 in 6ec4ac4

	downloadAndInstallTool :: HasTerm env
	=> Path Abs Dir
	-> SetupInfo
	-> DownloadInfo
	-> Tool
	-> (SetupInfo -> Path Abs File -> ArchiveType -> Path Abs Dir -> Path Abs Dir -> RIO env ())
	-> RIO env Tool
	downloadAndInstallTool programsDir si downloadInfo tool installer = do
	ensureDir programsDir
	(file, at) <- downloadFromInfo programsDir downloadInfo tool
	dir <- installDir programsDir tool
	tempDir <- tempInstallDir programsDir tool
	liftIO $ ignoringAbsence (removeDirRecur tempDir)
	ensureDir tempDir
	unmarkInstalled programsDir tool
	installer si file at tempDir dir
	markInstalled programsDir tool
	liftIO $ ignoringAbsence (removeDirRecur tempDir)
	return tool

the archive gets removed from disk ?
