If all goes well, we will be releasing 0.12 version of Leksah next weekend.

If you have time, can you please kick the tires?

The source we are planning to release is in github master branches of...
https://github.com/leksah/ltk

https://github.com/leksah/leksah-server
https://github.com/leksah/leksah

OS X Binary Installer

http://leksah.org/packages/leksah-0.12.0.0-ghc-7.0.4.dmg

Windows Binary Installers

http://leksah.org/packages/leksah-0.12.0.0-ghc-6.12.3.exe

http://leksah.org/packages/leksah-0.12.0.0-ghc-7.0.3.exe

http://leksah.org/packages/leksah-0.12.0.0-ghc-7.0.4.exe

Changes to the last release include:

* Support for GHC 7.2 and 7.4
* Better handling of navigation from text panes
* Addition of a Files pane

* Support for "cabal test"
* Better printer for cabal files (when Leksah is built with Cabal >1.10)
* Better candy support for literal Haskell

* Syntax highlighting for quasi-quoted hamlet, julius and cassius (DSLs used in Yesod)
* Several bug fixes and optimizations

Thanks to Sanny Sanoff for improving some of the keyboard navigation and symbol searching among other things.

Thanks to Harald Jagenteufel and Stephan Fortelny we have basic source control integration (git,svn) in a repo branch, but it is not part of this release. We hope to merge this in soon.

Work has been progressing on a major restructuring of Leksah to make it a modular plugin based system from the ground up. It is a big task and there is still more to do. Unfortunately this has meant we have spent less time adding features.

Hi,

I am now trying to install Leksah from upstream source but cannot build one of it's dependencies (glib). I guess building Leksah with GHC-7.4.1 will require some of its dependencies to be fixed first.

I've created a ticket on the glib bug tracker for this. http://hackage.haskell.org/trac/gtk2hs/ticket/1257

HTH,

Ozgur

Great news about the Leksah release (love Leksah!).

However, I have a mix of Macs, including an old 32-bit Core Duo Intel
(MacBook Pro) that has to run Snow Leopard rather than Lion.
Leksah 0.10.0.4 runs fine on this machine, but 0.12.0.0 won't run
because of a library dependency (see below).
Not sure if this is an oversight, or if 0.12.0.0 will now only run on
a later OS.

Thanks, it works great for me on Mac OX X Lion!

However, I am unable to build it on Linux (Ubuntu Natty) using GHC
7.0.4:

If I try to install gtksourceview2 on its own, I get an error complaining that "the package-cfg package gtk-sourceview-2.0 is not installed". Looks like I have libgtksourceview2.0 on my system... how can I check to see if it is version 2.0.2 or higher? And how can I update it?

Any help would be appreciated. I would love to be able to give Leksah a try on my Linux box. Thanks.

Lyle,
since I had previously the same error I can give you the hint to do:

sudo apt-get install libgtksourceview-dev

This is the c code which is needed by Leksah.
Good luck

Lyle,
to get these dependencies installed,

cabal install --only-dependencies

helped me a lot. I have now Leksah 0.12 running on Ubuntu 10.04.4 LTS
"Lucid"

I am very glad to have Leksah on my PC - it is very very nice!! Great
Job!
