You can (in some cases) successfully install and run it on windows, but you would need to go through certain steps installing some unrelated to windows software (gtk etc) No, there are no steps needed to install Gtk to run Leksah (the DLLs are included in the Leksah installer). You really only need to install the Haskell Platform and Leksah. If you want the grep feature to work you will need grep in your PATH. I would recommend leksah maintainers to change the language on their website to prevent future problems like this. We have prebuilt Windows installers that bundle everything you need to run Leksah. http://www.leksah.org/download.html If your GHC compiler is not listed there you can try out one of the development releases (0.13.2.4 is current). This version includes Gtk3 and some WebKit based features. https://groups.google.com/forum/#!topic/leksah/7A4gr8iem5c While it is true that it is currently hard to install Gtk for dev purposes on Windows, it is easy to install Leksah.

You will need Leksah 0.13 for GHC 7.6.3 and it is not in Hackage yet. It is almost ready though.

I am not able to reproduce this on my Ubuntu 12.10 VM. What version of GHC are you using? Do you have anything in your ~/.ghci file? What command are you running? Does putStrLn Hello World work?

Some things that will currently break it are... * Anything that tries to read input on stdin * :set prompt (Leksah uses the prompt to detect when the output finishes) I added some tests a while back to try to catch issues running GHCi.

[Haskell-cafe] ANNOUNCE : Leksah 0.12.1.2 (fixes some metadata issues)
This release has an important bug fix for the metadata download. When metadata was downloaded using libcurl it was not treated as binary data. If you used one of our binary installers or if you built Leksah with the -flibcurl flag then it is likely you have bad metadata files. To fix this please install Leksah 0.12.1.2, then delete your ~/.leksah-0.12/metadata folder to force Leksah to download the metadata files again. The first time you run leksah after doing this it will take a while for leksah to update the metadata (you can track its progress by looking in the metadata directory). If you choose to generate your metadata locally or you used wget to download (the default if you cabal installed leksah) then your metadata should be ok. There are some other bug fixes in this release including one for metadata generation for users with lots of .cabal files (some lazy IO was leaving file handles open).

Use GHC 6.12.3, 7.0.3 or 7.2.2 to cabal install cabal-install then run cabal install leksah-server. To work around it install GHC 7.0.4 or 7.4.1 and use it to run cabal install cabal-install (then you can go back to the old GHC if you want). Cabal experts, is there a better work around than this? The current leksah-server.cabal requires Cabal 1.10.2 or greater because it has a test-suite section for cabal test. This is fine if you have installed cabal-install with GHC 7.0.4 or 7.4.1, but if you install cabal-install with older versions of GHC (including 7.2.2) then it can't handle the file format. I could upload a new leksah-server to hackage (with the unit tests removed), but that would not stop cabal-install from failing to read leksah-server 0.12.0.3 and bombing out (there is already a 0.12.0.4 and it is not getting to that one). Even if you cabal unpack and then modify the .cabal file and run cabal install it still fails with the same error. If you can think of a better solution than asking users to install GHC 7.0.4 or 7.4.1 to build cabal-install, then please let me know. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

[Haskell-cafe] Experimental GHC with GHCJS built in and Cabal support for JavaScript files
Blackh and I have been trying out some ideas on how to make it easier use GHCJS in your Cabal projects. We took Victor's GHCJS code and added it back into GHC (we could not easily accomplish what we wanted using the current GHC API). We set it up so that GHC outputs a .js file whenever it outputs an object file. We added code to Cabal to install the .js files (in the same place as the .hi files). At link time GHC copies all the .js files from the packages used into a .jsexe directory (with the same name and in the same location as the executable). Finally when the executable is installed we copy the .jsexe directory along with it. Only files with differing modified dates are copied to avoid slowing things down too much. I have updated my yesod-slides example to show how all this can be used. https://github.com/hamishmack/yesod-slides The README.mardown there has instructions for building GHC and Cabal with the GHCJS stuff in it. It is a bit painful to build, but the changes to yesod-slides were quite minor... * Added ghcjs-rts to the build depends * Published the yesod-slides.jsexe folder (using Yesod's staticFiles) * Added script tags to head for rts-common.js and rts-plain.js * Added Julius script to init the rts Currently GHC is hard coded to use the GHCJS Trampoline calling convention (in GHC's HscMain.hs).

It's for test purposes only, I only need it made by ghc --make, I don't need a cabal package. $ cd code/euler $ leksah Euler.hs Ok so the problem here is that for leksah to work properly we really want a .cabal file. The other issue is that you can only have one cabal file per directory. This came up recently on the Leksah group and I have been pondering what to do. Can you try out this... ~/haskell/test$ cat ~/bin/cabal_quick_init #!/bin/sh SOURCE_FILE=$1 CABAL_NAME=`basename -s .lhs $SOURCE_FILE` CABAL_NAME=`basename -s .hs $CABAL_NAME` echo Creating Cabal Package $CABAL_NAME echo For file $SOURCE_FILE mkdir $CABAL_NAME.package || exit cd $CABAL_NAME.package || exit cabal init -n -p $CABAL_NAME --is-executable --source-dir=.. || exit sed -e s/-- *[mM]ain-[iI]s *\:/Main-is:$SOURCE_FILE/ -i $CABAL_NAME.cabal || exit ~/haskell/test$ cabal_quick_init Euler.hs Creating Cabal Package Euler For file Euler.hs Generating LICENSE... Warning: unknown license type, you must put a copy in LICENSE yourself. Generating Setup.hs... Generating Euler.cabal... Warning: no synopsis given. You should edit the .cabal file and add one. You may want to edit the .cabal file and add a Description field. This will make a Euler/Euler.cabal file. You can then simply add that .cabal file to your workspace (right click in the Workspace pane). If this works I will add something like it in Leksah as Package - Cabalize Existing Code. You will then be asked to choose a Main source file and if you need the package to be in a subdirectory. I'll try to fix leksah Euler.hs so it does the following * if the file belongs to an package in the workspace open the file and activate the package * if not ask the user if they want to simply open it or cabalize it So I understand why the package menus didn't work, but there was no alert while I was in leksah. And it did crash when I clicked on Package-Edit flags (reproductible) Now I create a workspace since I have to. On the browser I still don't have access to my file. Make workspace does nothing, and tells me nothing. I suspect I need a package. This is a bit crap. We have been thinking of adding a default workspace. But perhaps a better/simple solution is to prompt the user whenever this happens and ask if they would like to create a workspace or open an existing one. So I'm creating a package. When I click save, it creates a Main.hs file for me. Right now I'm kind of annoyed, I just wanted to edit Euler.hs, add another problem to it, compile, run, and get on with something else. That's usually where I close leksah, and lauch kate. For another programs (that compile fine with ghc --make), I didn't bother making the package. But I had to find out the package dependencies by building, checking where it fails, and trying to add a package to the dependency list. Maybe there's a better way, didn't find it. We do plan to fix this in the same way we resolve missing imports. I had a look to see if I could do it when a user cabalizes the source, but ghc --make -v does not include the packages automatically loaded in its output. Instead we will need to wait for the error then resolve it when the user presses Ctrl+R.

Re: [Haskell-cafe] what's the best environment for haskell work?
I use Leksah and have done since I started contributing to it. The best way to make it work for you is to use Leksah to fix what you don't like about Leksah ;-) Failing that giving good feedback about bugs and missing features is the next best thing.

Code completion makes the text jump if you're editing near the bottom of the editor area. You could turn on Edit Prefs - GUI Options - Complete only on Hotkey Default hotkey is Ctrl+Space I like the tocandy feature but then it breaks alignment if you open the file in another editor. Something probably fixable by editing the candy file. Just out of interest which of the candy replacements caused problems. Some of them (such as -) already are set to include spaces to pad out differences. You can turn candy off by unchecking Configuration - To Candy Does your existing editor handle candy better? If so how? I'am a bit lost between Workspace and Package, especially when all I want is write a quick single-source haskell program. We are planning to improve this by adding a default workspace and/or adding messages to prompt users if they have not got a workspace or package open. Basically to get started on a app Workspace - New Workspace (this file contains a list of packages to open) I think most users probably only ever need one workspace file. Next if you have a .cabal file already... Panes - Workspace (to show the workspace pane) Right click in the workspace Pane and select Add Package Or if you want to create a new package... Package - New Package Select a folder whose name matches the desired project name If you just click Save down the bottom you will get a very basic executable package with a Main module (but no main function) To switch between packages in your workspace just double click on it in the Workspace pane. That's all I can think of right now, I've exagerated a bit when I said unusable. Leksah is going to be an awesome editor, it's just not ready yet for me. Thanks for the feedback, please let us know if you think of anything else. As well as the google forum we now also have #leksah on IRC.

You can add them to the keymap.lkshk, but you will be limited to adding things leksah has commands for. If you do make some bindings please share them. We are working on integrating Yi as our editor instead of GtkSourceView and it has emacs keybindings. This integration is still in the early stages and I would not recommend trying to use it yet (unless you happen to have time to help out).

Anything even remotely similar here in New Zealand? The last couple of times I have visited my parents in (who live in Palmerston North), Stephen and I have got together for what we jokingly refer to as NZHac or the NZHUG. Our next trip to Palmy will be late August I think. There is an Erlang users group here in Wellington (organised by Lenz) and I attend when I can, there has not been a meeting in some time. It's really more of a FP group in a way as others that attending are not all Erlang users (but most use or would like to use a functional language of some sort). I think if we changed the name to the Wellington FP Users Group or something we might get more interest (especially if we catered to people interested in learning Scala and F#).

I am confused leksah depends on leksah-server so I am not sure how leksah could
build but not leksah-server, unless leksah were using some old version of
leksah-server installed earlier.
I'm at jhbuild build meta-gtk-osx-bootstrap step of GTK-OSX.
Once the next step (jhbuild build meta-gtk-osx-core) is finished, and all
is fine (and really I hope it), there are some consideration, before directly
reinstall cabal gtk packages, and reinstall leksah? I ask because it sais
thath jhbuild is needed to build gtk apps.
You will also need to
jhbuild build gtksourceview
jhbuild build ige-mac-integration
As for building gtk2hs, I have the following in them .profile and that seems to
be enough.
export PATH=/Users/hamish/gtk/inst/bin:~/.cabal/bin:$PATH
export XDG_DATA_DIRS=~/gtk/inst/share
export PKG_CONFIG_PATH=~/gtk/inst/lib/pkgconfig:/usr/lib/pkgconfig
Alternatively you could probably use 'jhbuild shell' to set up the environment
for you.
Then of course you will need to run...
cabal install --reinstall glib
cabal install --reinstall gio
cabal install --reinstall cairo
cabal install --reinstall pango
cabal install --reinstall gtk
cabal install --reinstall gtksourceview
If you do have half installed Leksah libs then run this...
cabal install --reinstall ltk
cabal install --reinstall leksah-server
cabal install --reinstall leksah
You can make Leksah look a bit nicer too with
jhbuild build gtk-engines
Then to your ~/.gtkrc-2.0 file (or your ~/.gtkrc.mine file if if appropriate)
add something like...
include /Users/hamish/gtk/inst/share/themes/Clearlooks/gtk-2.0/gtkrc
style leksah-close-button-style
{
GtkWidget::focus-padding = 0
GtkWidget::focus-line-width = 0
xthickness = 0
ythickness = 0
}

Pressing the tab key in Leksah inserts spaces to take you to the appropriate
place. Backspace key does not currently work as well as it should to go back a
level of indentation.
Using tab characters in Haskell code is a bad idea...

Do not use tabs. At all. Now all programs look identical everywhere, and

[Haskell-cafe] Improving Haskell on Windows by adding it to TakeoffGW
Finally someone has created a working MinGW distribution with a package manager! http://sourceforge.net/apps/mediawiki/takeoffgw/index.php?title=Main_Page Pier11 has done a great job of making MinGW libraries, tools and apps easy to install. It may seem limited at this stage (compared to what is available on linux), but it is a darn site better than fishing around for a combination of prebuilt binaries or building everything from source. I think we should embrace this project and try to add support for installing Haskell using it (GHC, Haskell Platform, Darcs, Gtk2Hs, Leksah, ...). You can read the comments here to get a feel for just how Windows users feel about TakeoffGW... http://www.reddit.com/r/programming/comments/c9duj/takeoffgw_mingw_based_distribution_with_a I tried it out myself and had Gtk2Hs and Leksah up and running in no time using TakeoffGW to install all the prerequisites.

[Haskell-cafe] Patch to add process group support
The attached patch for the process package adds support for creating and interrupting process groups on Unix and Win32 systems. Currently we have to use a nasty hack in Leksah that only works on Unix systems (and even then not very well). On Win32 Leksah's background build feature is dreadful as a results (because it has no way to interrupt the build and start over when the user makes more changes). I would love to get this onto Hackage somehow, if not as a new version of the process package, perhaps as an alternative package (process-groups using System.Process.Groups instead of System.Process). Please can you have a look and let me know what you think? Thanks, Hamish This patch introduces the following functions to System.Process * runCommandNewGroup, runProcessNewGroup, runInteractiveCommandNewGroup and runInteractiveProcessNewGroup __ These are variations on the existing functions for running processes. They create the child process as the lead process in a new process group. Unix - calls setpgid in both the parent and the child process after fork. Win32 - calls CreateProcess with the CREATE_NEW_PROCESS_GROUP set. I also had it unset CREATE_NO_WINDOW because this seems to prevent the child attaching to the parents console (and therefor stops interuptProcessGroup from working). * interruptProcessGroup This function can be used interrupt a running process group. Unix - calls signalProcessGroup to send sigINT Win32 - If the process ID is known it calls generateConsoleCtrlEvent to send cTRL_BREAK_EVENT __ Compatibility __ Backward Compatibility CreateProcess has a new field new_group which may need to be added to some existing code. If set to False the current behaviour is preserved. As far as I know this is the only change that could break existing code. Linker Errors I have renamed the C functions it used in order to prevent linker errors when using this new version with the existing process package. __ Win32 Only __ On Win32 the process handle is not the same as the process ID and there is no reliable way to convert from one to the other. I have added an interface that allows access to the process ID, but does not change the behaviour of the existing functions. * PINFO Replaces PHANDLE in the ProcessHandle type. type PINFO = (PHANDLE, Maybe Word32) -- Handle and Process ID * mkProcessHandleWithPID Like mkProcessHandle but allows you to specify the processes ID as well. This function is now used in all the run functions so the ProcessHandle they return will contain a process ID. * withProcessInfo and withProcessInfo_ Like withProcessHandle functions but gives you access to the PINFO (not just the PHANDLE it contains).

Re: [Haskell-cafe] ANN: Leksah 0.6
2009/7/25 Thomas Davie tom.da...@gmail.com: The new detach feature is great, it makes it much more usable for OS X users, but there's a small problem – if you detach the main source window (from the default config), you end up with a window containing just the package management/documentation stuff, which is great, but I'd like to be able to shrink it down. You can't unfortunately because of the toolbar. Would it be possible to move the toolbar onto the document windows rather than the package window. Try this... start with the default layout (rm ~/.leksah/Current.session) click on the Modules tab (make sure it says Modules in the status bar) View - Collapse (this will combine the two panes on the right into one) View - Detach (this will detach them leaving the main toolbar behind) Hamish ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
