GOA ~~ GHCi On Acid

This set of tools is an attempt to bring the wonderful world of lambdabot commands to the GHC interpreter for ease of use.

The set of commands carefully developed in lambdabot during the years has become a very useful tool for haskellers. For some it is like an addiction.

Installation

-- Add the path to lambdabot's directory to dot-ghci $ vi dot-ghci

-- Build $ chmod +x Setup.hs $ ./Setup.hs configure --prefix=/home/dons $ ./Setup.hs build $ ./Setup.hs install

-- Add dot-ghci to your default ghci setup $ cat dot-ghci >> ~/.ghci

Use

$ ghci

Extending

Define new commands with:

    :def command lambdabot "lambdabot-command-name"

Documentation

The documentation ought to be compliant with the specification of khjk-structured-text by Sven Moritz Hallberg http://www.khjk.org/~sm/.

Dependencies

[Lambdabot]: http://www.cse.unsw.edu.au/~dons/lambdabot/. [khjk-structured-text]: If you want to produce HTML documentation.

Additional Fun
