Re: [Haskell-cafe] cabal v2 global install status

Hi, I'd love to know more about that script capability, if you can spare the time to explain a bit. It can be a separate thread or via private email if that may be noise in the conversation. All the best, Ivan On Thu, 5 May 2022 at 15:11, Brandon Allbery wrote:

Cabal has a script capability, although it's poorly documented.

For one-liners, there is `cabal repl --build-depends='...'. Not ideal, perhaps, but works well enough for me.

This workflow (installing packages in a store in the project directory) should be not just supported, but *encouraged*. Keeping all changes local *should be the default*.

and those who want to optimize installation times, avoid re-compilation, those who know how to navigate $HOME/.cabal if need be, etc., can then choose to share that installation directory across projects and use $HOME/.cabal instead (or whatever else they want). But that's a conscious choice made by an expert who understands the choice.

I'm actually coming from a bit of the opposite perspective. :)

I'm pretty happy, overall, with `cabal new-repl`, `cabal new-build`, etc. What I miss is the ability to have global installs. More specifically, I want to *pay all my costs at install time*. I'm okay with futzing with

Experts, package dependencies, etc. (e.g. resolving conflicts in transitive dependencies) when installing a new package, but once I've paid that cost I want to be able to simply run `ghci` and have my curated set of packages available to me. I don't want to have to `mkdir foo ; cd foo ; cabal init ; $EDITOR cabal.project ; cabal new-repl` just to run a simple one-liner in ghci. I also like being able to write quick scripts and run them with `runghc` without creating an entire project for each and every one.
