I’m looking to appreciate “retro” Haskell projects, things from before stabilization/company use. Such as: fgl https://web.engr.oregonstate.edu/~erwig/fgl/haskell/ https://web.engr.oregonstate.edu/~erwig/fgl/haskell/ WWWBrowser https://cth.altocumulus.org/~hallgren/wwwbrowser.html https://cth.altocumulus.org/~hallgren/wwwbrowser.html Balsa/Teak (languages) http://apt.cs.manchester.ac.uk/projects/tools/balsa/ http://apt.cs.manchester.ac.uk/projects/tools/balsa/ BlueSpec compiler https://github.com/B-Lang-org/bsc https://github.com/B-Lang-org/bsc The CABAL spec (Common Architecture for Building Applications and Tools) https://www.haskell.org/cabal/proposal/index.html https://www.haskell.org/cabal/proposal/index.html Frag (that one Haskell game) https://wiki.haskell.org/Frag Hugs string extensions https://www.haskell.org/hugs/pages/users_guide/here-documents.html https://www.haskell.org/hugs/pages/users_guide/here-documents.html I guess darcs/c2hs/happy/alex count, they have history! Bonus points for Makefiles to build the project Professor-HTML project page Hugs support Haskell 1.4 etc. support
