GOA ~~ GHCi On Acid
===================

AUTHOR : Paolo Martini
Maintainer at HackageDB: Chris Done <chrisdone@gmail.com>

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.

The goa needs lambdabot too. 
Check http://hackage.haskell.org/package/lambdabot

Installation
------------

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

-- Build
    $ chmod +x Setup.hs
    $ ./Setup.hs configure --user
    $ ./Setup.hs build
    $ ./Setup.hs install

-- Add dot-ghci to your default ghci setup. Change setLambdabotHome 
-- according to where your lambdabot is.
    $ cat dot-ghci >> ~/.ghci

Use
---

    $ ghci

Pointfree refactoring

    Prelude GOA> :pl \f x y -> x * y
    const (*)

Search for functions
    Prelude GOA> :index const
    Prelude

Search for documentation
    Prelude GOA> :docs Prelude
    http://haskell.org/ghc/docs/latest/html/libraries/base/Prelude.html

Find source
    Prelude GOA> :source Prelude

Search by name
    Prelude GOA> :hoogle const
    Prelude.const :: a -> b -> a

Search by type
    Prelude GOA> :hoogle a -> [a] -> a
    Prelude.foldl :: (a -> b -> a) -> a -> [b] -> a
    Prelude.foldr :: (a -> b -> b) -> b -> [a] -> b
    Data.List.foldl' :: (a -> b -> a) -> a -> [b] -> a


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/>.
[Lambdabot now on HackageDB]: <http://hackage.haskell.org/package/lambdabot>
[khjk-structured-text]: If you want to produce HTML documentation.

Additional Fun
--------------

Look in fcgi for a fastcgi binding for lambdabot.
