The Haskell/Gtk+ Integrated Live Environment

Latest on Hackage:0.2.2

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow to host generated Haddocks.

Manatee is Haskell integrated environment written in Haskell.

The goal of the Manatee project is to provide a fast, safe and flexible integrated environment for haskell hacking.

You can consider it is new environment mix Gnome and Emacs. Like Gnome to provide friendly graphics interface and work efficient like Emacs.

Manatee use multi-processes framework, any sub-module running in separate process to protected core won't crash. So it minimize your losses when some unexpected exception throw in extension.

Below is build step for Manatee:

1) Install gold-linker to accelerate installation:

I suggest use gold-linker instead ld to accelerate installation.

In Debian system, you just need do below command:

sudo aptitude install binutils-gold -y

This step is optional, it's okay use ld link program, just much slow. :)

2) Install GHC compiler

Download ghc package for your system, then do below command :

./configure && sudo make install

3) Install C library: In Debian use below command:

sudo aptitude install libgtksourceview2.0-dev libgconf2-dev libwebkit-dev libcurl4-openssl-dev libgtkimageview-dev libpoppler-glib-dev poppler-data libtagc0-dev libvte-dev -y

4) Install cabal:


Decompress cabal-install-0.10.2.tar.gz and do below command:

cd ./cabal-install-0.10.2 && sudo chmod +x ./ && ./

5) Install dependent Haskell library:

First make sure HOME/.cabal/bin/ in your PATH

Generic way is add PATH=$PATH:~\/.cabal\/bin in your ~/.bashrc

Then do below command (NOTE: don't use root permission with cabal, otherwise Manatee can't work):

cabal update && cabal install alex happy c2hs && cabal install gtk2hs-buildtools glib gio pango cairo gtk

6) Install Manatee:

Install all Manatee packages (same, don't use root permission):

cabal install manatee-all

If you don't want install all Manatee packages, you can install basic package like below:

cabal install manatee-core manatee-welcome manatee

Then choose extension package list in below to install:


Note if you don't install any extension package, nothing will show in manatee, so you at least to choose one extension to install.

That's all, then type command "manatee" to play it! :)

I have test, Manatee can works well in Gnome, KDE, XMonad and XFCE

Manatee is distributed framework, it allowed you install extension don't need depend each other, but it's easy to break if some package is older than core packages (manatee-core, manatee). So please make sure *all* packages has update to newest version before you report bug to . Thanks! :)
