stack-clean-old
A small tool to clean away older Haskell stack snapshot builds and ghc versions to recover diskspace.
Usage
stack-clean-old [size|list|remove|keep-minor|purge-older|delete-work] [(-P|--project)|(-G|--global)|(-C|--compilers)|(-T|--tarballs)] [(-s|--subdirs)|(-r|--recursive)] [-d|--delete] [GHCVER]`
In a project directory it acts on .stack-work/install/ by default,
otherwise on ${STACK_ROOT}/{snapshots,programs}/
(the default Stack root is ~/.stack/):
see the Stack root documentation.
Subcommands:
size:
prints the total size of .stack-work/ of project(s) or the Stack root.
directories (size does not take a GHCVER argument).
list:
shows the total size and number of snapshots per ghc version
(the GHCVER argument is optional).
remove:
removes for the specified ghc version (the GHCVER argument is required).
keep-minor:
removes the builds/installs for older minor releases of ghc major versions.
If GHCVER is given then only minor versions older than it
(or than the latest installed minor version) are removed.
If no GHCVER is given it applies to each installed ghc major version.
purge-older:
removes snapshot builds with older timestamps
delete-work:
removes .stack-work directories completely
dry-run mode is used by default and one should use --delete (-d)
for actual deletion of files, after checking the dry-run output.
If you should remove any needed snapshot builds, then they will get rebuilt again by stack next time you build any projects needing them, so removals should be done carefully but can recover a lot of diskspace.
Further the commands can use --subdirs or --recursive to run over
the projects in subdirs under the current directory or
all matching .stack-work dirs from the current directory and below
respectively.
If you have different ghc variants/archs installed
you can use --platform to restrict to one of then,
otherwise they are each listed by default.
Example usage
List a project’s builds:
$ stack-clean-old list
149M 9.2.8 (5 dirs)
163M 9.4.7 (5 dirs)
155M 9.6.2 (5 dirs)
Remove project’s 9.0.2 builds:
$ stack-clean-old remove --delete --project 9.0.2
:
(–project is optional in a project dir).
Remove stack ghc-9.4 snapshot builds and minor compilers before 9.4.7:
$ stack-clean-old list --global 9.4
x86_64-linux-tinfo6:
1.8G 9.4.6 (61 dirs)
279M 9.4.7 (6 dirs)
x86_64-linux:
ghc-tinfo6-9.4.6
ghc-tinfo6-9.4.7
$ stack-clean-old keep-minor --global 9.4
ghc-tinfo6-9.4.6 compiler would be removed
x86_64-linux-tinfo6:
61 dirs in ~/.stack/snapshots/x86_64-linux-tinfo6/*/9.4.6 would be removed
(use --delete (-d) for removal)
$ stack-clean-old keep-minor --global 9.4 -d
ghc-tinfo6-9.4.6 compiler removed
x86_64-linux-tinfo6:
61 dirs in ~/.stack/snapshots/x86_64-linux-tinfo6/*/9.4.6 removed
(–global is optional outside a project dir).
If you have different latest minor versions for compilers and snapshots you may prefer to specify the latest minor version to keep to get more certain behaviour.
Purging older stack project builds
stack-clean-old purge-older
This command removes older stack builds from .stack-work/install/.
By default it keeps 5 newest builds per ghc version.
The preservation/deletion is calculated and done per ghc version.
NB: If you regularly build your project for several branches/tags against the same LTS or ghc version then it is safer to avoid using purge-older.
Deleting all .stack-work/ subdirectories
stack-clean-old delete-work --recursive can be used to remove recursively
all .stack-work/ dirs within (or outside) a project directory to save
space (seems same as stack clean --full inside a project).
Help output
(Note you can also run this tool via stack clean-old.)
To get help you can run stack-clean-old --help or just:
$ stack-clean-old --version
0.5
$ stack-clean-old --help
Stack clean up tool
Usage: stack-clean-old [--version] COMMAND
Cleans away old stack-work builds (and pending: stack snapshots) to recover
diskspace. Use the --delete option to perform actual removals.
https://github.com/juhp/stack-clean-old#readme
Available options:
-h,--help Show this help text
--version Show version
Available commands:
size Total size
list List sizes per ghc version
remove Remove for a ghc version
keep-minor Remove for previous ghc minor versions
purge-older Purge older builds in .stack-work/install
delete-work Remove project's .stack-work/ (optionally
recursively)
Command options
Most of the commands have similar options, e.g.:
$ stack-clean-old remove --help
Usage: stack-clean-old remove [(-d|--delete) [-y|--yes]]
[(-P|--project) | (-S|--snapshots) |
(-C|--compilers) | (-T|--tarballs) |
(-G|--global)]
[(-s|--subdirs) | (-r|--recursive)] GHCVER
[-o|--platform SYSTEM]
Remove for a ghc version
Available options:
-d,--delete Do deletion [default is dryrun]
-y,--yes Assume yes for all prompts
-P,--project Act on current project's .stack-work/ [default in
project dir]
-S,--snapshots Act on ~/.stack/snapshots/
-C,--compilers Act on ~/.stack/programs/ installations
-T,--tarballs Act on ~/.stack/programs/ tarballs
-G,--global Act on both ~/.stack/{programs,snapshots}/ [default
outside project dir]
-s,--subdirs List subdirectories
-r,--recursive List subdirectories
-o,--platform SYSTEM Specify which OS platform to work on (eg
'x86_64-linux-tinfo6', 'aarch64-linux-nix',
'x86_64-osx', 'aarch64-osx', etc)
-h,--help Show this help text
(The list and size commands don’t have --delete and --yes.)
Installation
Run stack install or cabal install
Related
This tool complements stack-all which builds projects across LTS major versions and hence generates a lot of stack builds.
cabal-clean is a similar tool for cleaning old cached cabal build files.
