This seems like a useful tool, but the naming might be confusing: "cabal-install" generally means "cabal install" but "cabal-clean" and "cabal clean" have similar goals but behave differently. Tom On Fri, Sep 24, 2021 at 07:09:49PM +0200, Andreas Abel wrote:

`cabal-clean` is a small executable that removes outdated cabal build artifacts from `dist-newstyle`.
A build tree is considered outdated if there is one with either
- a newer version of the package you are building, or - a newer minor version of the GHC compiler.
In contrast to `cabal clean`, the tool `cabal-clean` retains the latest build trees for each GHC major version. Thus, it is geared towards multi-GHC development.
Example: (self-applied to cabal-clean's build directory)
--- 3.7M ghc-8.8.4 /cabal-clean-0.1.20210815 --- 3.5M ghc-8.10.6/cabal-clean-0.1.20210815 --- 3.7M ghc-9.0.1 /cabal-clean-0.1.20210815 --- 3.5M ghc-8.10.6/cabal-clean-0.1.20210924 +++ 3.6M ghc-8.10.7/cabal-clean-0.1.20210924 +++ 3.7M ghc-9.0.1 /cabal-clean-0.1.20210924
The directories prefixed with --- will be deleted, the ones with +++ retained.
Disclaimers:
1. cabal-clean does not check whether deletion will cause dangling references like broken symlinks etc. (Could happen if you created a symlink to an executable that resides in one of the deleted build directories.)
2. cabal-clean does not read nor utilize information from the .cabal file.
3. Calls `du` ("disk usage"), so, might not work on Windows.
