[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.

You could turn on Edit Prefs -> GUI Options -> Complete only on Hotkey 

Default hotkey is Ctrl+Space

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?

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.

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.
