stack-clean-old

A small tool to clean away older Haskell stack snapshot builds and ghc versions, to recover diskspace.

Usage

stack-clean-old [project|snapshots|ghc] [size|list|remove-version] [GHCVER]

These commands act respectively on:

• the current local project (.stack-work/install/)
• the user's stack snapshot builds (~/.stack/snapshots/)
• installed stack ghc compilers (~/.stack/programs/).

size: prints the total size of the above directory (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-version: removes all snapshots for the specified ghc version (the GHCVER argument is required).

NB: If you remove all snapshot builds for a version of ghc, then you would have to rebuild again for any projects still using them, so removal should be used cautiously, but it can recover a lot of diskspace.

Purging older stack project builds

stack-clean-old project remove-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 multiple branches/tags against the same LTS or ghc version then it is probably safer to avoid using remove-older.

Installation

Run stack install or cabal install
