------------------------------------------------------------------------------

Hugs was a popular implementation of the Haskell programming language in the 1990s. Maintenance of it stopped in 2009, three years after the final release in 2006.

I have updated the source code of the original 2006 distribution to make it build again today, on Mac OS X in particular.

I am maintaining this repo of Hugs for historical purposes.

I have not tested other platforms but would welcome verification or additional portability fixes). I did not start with the development version as of 2009 because of uncertainty about any changes introduced since 2006.

I have provided a Homebrew formula so that if you are on Mac OS X, you can install Hugs as follows:

$ brew install FranklinChen/tap/hugs --HEAD

(If you are curious, you can look at my Homebrew tap repo here.)

Or, to install by yourself from this repo:

$ brew upgrade
$ brew install readline
# If you want to use X11 and ALUT:
$ brew install libx11 freealut
$ export LDFLAGS="-L/opt/X11/lib -L$(brew --prefix)/opt/freealut/lib"
$ export CPPFLAGS="-I/opt/X11/include -I$(brew --prefix)/opt/freealut/include"
$ export CFLAGS="-Wno-error=implicit-function-declaration -Wno-error=implicit-int"
$ ./configure
$ make
$ make install

For real life work in Haskell, please use GHC, which comes with

• a Hugs-inspired interpreter ghci that works just like Hugs, except better.
• an industrial-strength optimizing native compiler ghc, which generates code running hundreds of times faster than interpreted ghci and comparable to C speed.
• access to a huge ecosystem of libraries called Hackage.

On Mac OS X, it's very easy to get going with using GHC. I recommend using Homebrew to install everything you need to get started, whether you choose to use GHC and Cabal, or Stack, which is what I prefer to use.

$ brew install ghc
$ brew install cabal-install
$ brew install  haskell-stack
