Hashell : A Haskell shell
-----------------------------------------
Version: 0.014a
Status: Alpha
Dependencies:
*The Glasgow Haskell Compiler
>= 6.8 <http://haskell.org/ghc>
*Cabal
(any version should work fine; <http://haskell.org/cabal>)
*Parsec
>= 1.0 <http://www.cs.uu.nl/people/daan/parsec.html>
You can build and install Hashell like any other Haskell package, through Cabal; the following example installs as the current user to one's ~/bin directory, but to install elsewhere or as root, simply change the directories or remove the --user flags, respectively:
$ runhaskell Setup configure --verbose=2 --user --prefix=$HOME/bin --datadir=$HOME/bin/share
$ runhaskell Setup build
$ runhaskell Setup install --user;
You need to have Cabal installed in your system.
Cabal will often be part of your GHC installation, but you can get a stand-alone version of Cabal from <http://haskell.org/cabal>.
NOTE! The current version of Hashell assumes you have GHC 6.8.2 installed, and that the output of 'ghc --print-libdir' = "/usr/lib/ghc-6.8.2/". If that's not the right directory, you must edit Hashell/Eval.hs and update the constant 'ghcPath'.
Usage:
$ hashell
or
$ hashell -c <configurationfile>
You always can use the --help option for further help.
$ hashell --help
The syntax is still fluid, but roughly, ';' is a terminator; an expression starting with ':' will be treated as a load-file command; one starting with "quit" will exit Hashell; one starting with "cd" will change the working directory; and an expression enclosed in a "!()" will be passed through the GHC API and evaluated as an arbitrary Haskell expression. All other commands should be treated as programs to be run.
