Thanks, Michael. For what it's worth, I actually do all of my scion-server
development in EclipseFP to prove that I can proverbially "eat my own dog

> you don't have a preference.
> 3. Install the EclipseFP <http://eclipsefp.sourceforge.net/> plugin
> In Eclipse go to Help > Install New Software and paste
> http://eclipsefp.sf.net/updates into the Work with: field - hit enter.
> In the box below "Functional Programming" should show up after a few
> moments, cancel and retry it if it doesn't. Expand "Functional Programming"
> and check the 2.x.x Haskell Support plugin. Follow the rest of the steps,
> and EclipseFP will be installed, and will prompt you to restart Eclipse.
> 4. Update Cabal
> While you're waiting, launch a command prompt window (type cmd in the
> start bar on Win Vista/7) or terminal and enter 'cabal update'. This will
> update the packages Haskell needs in order to let EclipseFP work.
> 5. Configure EclipseFP
> Go to Window > Preferences and expand the Haskell section. Click on
> "Haskell Implementations" and click "Add". Enter a reasonable name (I
> called it "Haskell Platform") and then browse to the bin directory of your
> GHC installation, which on Windows is something like "C:\Program
> Files\Haskell Platform\2010.2.0.0\bin". It will populate the Version and
> Library folder items below, click Ok. Click OK to save these preferences,
> then open the preferences window again. Go to "Scion and Cabal" and click
> "Autodetect" on the right. It should add an item to the list of Installed
> Cabal implementations, but if it does not, click add, give it a name like
> "Cabal" and give it the path to the Cabal executable, which on Windows is
> something like "C:\Program Files\Haskell
> Platform\2010.2.0.0\lib\extralibs\bin\cabal.exe". Hit OK, and click Rebuild
> on the right to tell EclipseFP to build the "Scion server" which handles the
> syntax highlighting and file parsing. Optionally under Editor check "Show
> line numbers" and uncheck "Show print margin", I think it makes the editor
> pane look better. Then hit OK to exit preferences.
> 6. Build the Scion Server
> In theory, upon exiting the preferences window, EclipseFP will start
> doing a lot of work to build the Scion server. If it does not, simply exit
> and restart Eclipse, and when it's restarted it will start building. With
> any luck, this will run for a few minutes and then be done, however you may
> run into some trouble due to the finicky nature of Haskell's/Cabal's
> versioning system. If it fails, try running "cabal update" again, or
> running something like "cabal install network-2.3" where network-2.3 is
> a package the build script reported wasn't right. Once the Scion server is
> built, we're basically all set. Restart Eclipse one more time for good
> 7. Create a Haskell Project
> Switch to the Haskell perspective if this hasn't happened already - top
> right corner, click the Open Perspective icon, click Other if you don't see
> Haskell in the list, and select Haskell from the popup. Now go to File >
> New > Haskel Project (or Project and then select Haskell Project) and create
> a project. To create your first Haskell file, right click on the src
> flolder in the project and select New > Haskell Module. This creates a
> Haskell file, you can do whatever you want with it. To run the file, click
> the Run button (green circle, white triangle) near the top. This will
> launch a basic GHCi terminal in the Console tab below with the prompt
> "Prelude>" if the file has errors, or "MODULENAME>" if it compiled
> successfully. You can use this like the external GHCi terminal to run
> commands like :t, or to make function calls of the module.
> 8. Configure How The File Runs
> One last thing which will make your life easier is to tell EclipseFP to
> automatically reload the file when it's saved, and to run a function (for
> instance "main") after the file is reloaded. To do this, click on the down
> arrow next to the run button, and select "Run Configurations". Click on the
> configuration on the left of the file you want, then click on the Automation
> tab. Check "Reload packages on save" if you don't want to have to type ":r"
> all day, and type a function name like "main" and check "Rerun command after
> reload" to run a command automatically.
> WHEW. That's a lot of writing, but believe it or not it's pretty
> straightforward to setup, especially since I've already figured this stuff
> out for you (most of it's not documented!). I'm happy to give you a hand
> setting this up if you run into any trouble.
