I haven't written any #Haskell in years, so I decided to do one little shell script, just to see if I remember.

Some random thoughts:

• The Turtle lib is awesome (https://hackage.haskell.org/package/turtle-1.6.2/docs/Turtle-Shell.html)
• Haskell is also awesome as always.

• The tooling and documentation still leaves you feeling stupid (unlike, PureScript, for example)
• I hate this packing and unpacking of strings.

Oh, and here is the script, feedback and questions are welcome:

I’m pleased to announce shelltestrunner 1.10 !
This is a cross-platform, GPLv3+ command line tester.
It tests one or more commands, with optional input, and their expected output, stderr, and exit status. It can run tests in parallel, selectively, with a timeout, in color, etc. 1.10 brings --print mode (useful for upgrading old format 1 tests to to modern format 3), and precise line number reporting.

FunGEn is a BSD-licensed, cross-platform, OpenGL-based game engine written in #Haskell. Created by Andre Furtado in 2002, it's the oldest Haskell game engine and still one of the easiest ways to get started with Haskell game development. I have released a cleaned-up https://hackage.haskell.org/package/FunGEn 1.2, tested up to ghc 9.6.

I don't have time to do more with it, but it's still useful - would you like to take it over, make a slick home page, and build more haskell games ?
