Leksah, an Integrated Development Environment for Haskell

Build Status

Leksah aims to integrate various Haskell development tools to provide a practical and pleasant development environment. The user interface is a mix of GTK+ and WebKit based components.

Documentation can be found on leksah.org.

Getting Leksah

Leksah requires you have ghc >= 7.10.3 and cabal-install >= 1.24 installed

Building from source

Requirements: ghc >= 7.10.3, cabal-install >= 1.24

We have just completed a port of Leksah from Gtk2Hs to haskell-gi. Not all of the code is in Hackage yet so to build it you can either use Xobl or follow the instructions below.

Step 1. Install the following C libraries


sudo dnf install gobject-introspection-devel webkitgtk3-devel gtksourceview3-devel


sudo apt-get install libgirepository1.0-dev libwebkitgtk-3.0-dev libgtksourceview-3.0-dev

Arch Linux

sudo pacman -S gobject-introspection gobject-introspection-runtime gtksourceview3 webkitgtk

OS X MacPorts

sudo port install gobject-introspection webkit-gtk3 gtksourceview3 gtk-osx-application-gtk3 adwaita-icon-theme

You will also need to build a MacPorts compatible of GHC. First install GHC some other way then unpack the source for the GHC version you want to use and run:

sudo port install libxslt gmp ncurses libiconv llvm-3.5 libffi
./configure --prefix=$HOME/ghc-8.0.1 --with-iconv-includes=/opt/local/include --with-iconv-libraries=/opt/local/lib --with-gmp-includes=/opt/local/include --with-gmp-libraries=/opt/local/lib --with-system-libffi --with-ffi-includes=/opt/local/lib/libffi-3.2.1/include --with-ffi-libraries=/opt/local/lib --with-nm=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/nm-classic
make install

Then make sure the $HOME/ghc-8.0.1/bin is in your $PATH.

OS X Homebrew

Homebrew Does not have WebKitGTK 2.4.x (newer versions of WebKitGTK only have WebKit 2 interface)

Windows MSYS2

Install MSYS2 and Chocolatey. Then in a shell with administrator privileges:

choco install ghc
pacman -S mingw64/mingw-w64-x86_64-pkg-config mingw64/mingw-w64-x86_64-gobject-introspection mingw64/mingw-w64-x86_64-gtksourceview3 mingw64/mingw-w64-x86_64-webkitgtk3

Step 2: Install tools

cabal update
cabal install alex happy
cabal install haskell-gi

(make sure ~/.cabal/bin is in PATH)

Step 3: Clone the repo

git clone --recursive https://github.com/leksah/leksah.git
cd leksah

Step 4: Build and Run Leksah

OS X using MacPorts

Run leksah.sh like

XDG_DATA_DIRS=/opt/local/share ./leksah.sh
Other OS



Using stack build instead of cabal new-build

** NOTE : Building Leksah with stack is currently not working. If you can make it work let us know how you did it. **
