Leksah: an IDE for Haskell written in Haskell

This is the Leksah users' wiki. Leksah is in active development. We plan to release a first beta soon. For general information:

  • Contact us for further info (info at leksah.org)

Contents

1 Installation

  • First look to the general information in the Manual
  • When you get the following error:

src/IDE/Completion.hs:87:26:

   Not in scope: `sourceLanguageManagerGuessLanguage'

you have to install gtksourceview2 in a version > 2.4.0

  • When you get the following error:

Linking dist/build/leksah/leksah ... /usr/bin/ld: cannot find -ledit collect2: ld returned 1 exit status

you have to install libedit development files.

  • The package type-level considered toxic!

This package defines > 20000 newtypes for numbers and wastes a lot of space for metadata. So consider to unregister it, if you don't really need it.


2 Release notes

Moved to the Leksah webside

3 Installation on Windows from scratch

In the future when Leksah reaches production quality I hope we can provide a Windows installer.

This is what you can do to get leksah 0.4.3 running on Vista

0. cabal-install was not working for me. Probably because currently there is no gtk2hs >= 0.10.0 on Hackage right now.

1. Install your GHC from http://www.haskell.org/ghc. Duh. Mine was GHC 6.10.1.

2. Install gtk2hs from http://www.haskell.org/gtk2hs/ or Sourceforge.net. It was 0.10.0 when I checked.

3. Install Cygwin with the online installer from http://www.cygwin.com/ Select packages wget, curl and gcc-core in adition to the standard selection. I used the 1.7.0 version of Cygwin setup, but it is still beta.

4. Download darcs from http://wiki.darcs.net/DarcsWiki/Binaries, unpack it in under Program Files and add the path to your environment variables. The file I downloaded was darcsdir-cygwin-2.2.0.tar.bz2.

5. Download the GHC sources from http://www.haskell.org/ghc. Open a Cygwin shell, make a directory Haskell, copy the source tarballs here and unpack them.

6. Download the binary and utf-8 packages from Hackage and copy them to the Haskell folder. Open a Cygwin shell in Administrator mode and unpack the tar files. Go to the directories and do runhaskell Setup configure, runhaskell Setup build, runhaskell Setup install.

7. In the Haskell directory do a darcs get http://code.haskell.org/leksah. Go to the leksah directory and do a runhaskell Setup configure, runhaskell Setup build, runhaskell Setup install.

7a) Although I probably didn't get this, previously some gtk error message was resolved by editting C:/Program Files/Gtk2Hs/0.10.0/etc/gtk-2.0/gtkrc and change the theme name from MS-Windows to Raleigh: gtk-theme-name = "Raleigh"

8. You may wish to install a full Unicode monospace font if you want to use the source candy feature of leksah. e.g. Everson Mono or Deja Vu Sans Mono.

9. Start leksah and give your Haskell directory as source root. Select the right font from Help/Prefs.

10. Have fun with leksah, but remember it is a beta version!
