Alas for me (in IE8) this isn't working. It doesn't seem to actually "execute".

Yeah, me either--I keep getting either (seemingly arbitrary) double prompts or "ajax errors" in Safari 5.0.3...

Not working in Chrome. I pressed send and it just printed back everything in the editor without executing.

I had this problem, and then I noticed that I had allowed scripts from tryfs.net, but not tryfs.com. It worked after that, though not very cleanly.

Does not work very well in Chrome, IE8, or FF. Does not allow pasting. Not really sure what it's good for except to show off an interesting hack, and the hack needs some improvement.

Ever wonder what the 200,000th Fibonacci number is? Last night with a recursive F# function I got it in FSI in just over 6 seconds. It would be cool if you could get this page to work well enough to do that.

It didn't like this :( It should list out all files from C:\

    let root =  "C:\\";
    let getdirs dir = 
      try
        System.IO.Directory.GetDirectories(dir)
      with 
        | e -> Array.empty

    let rec list_files dir = seq {
      yield! System.IO.Directory.GetFiles(dir);
      for subdir in (getdirs dir) do
        match subdir with 
        | x when x.StartsWith("C:\\$") -> ()
        | subdir -> yield! list_files subdir
  
    }

    list_files root
    |> Seq.iter (printfn "%s")

    printf "done"

All types inferred.

Thanks for this - I'll take a look. The same code works fine when run through regular fsi.exe, so presumably something is going amiss over the Ajax interface.

It works here, but lists certain files from the system, and stops at "Documents And Settings" - no rights etc.

I had to pad the first "let" to be at the same padding as the second one

The app got into a state where new fsi.exe processes wouldn't start up properly - they'd raise an unhandled exception and hang. I started being more diligent about cleaning up old processes.
