F# on mono (Ubuntu 7.10) and fsi.exe
f#

Hi,
I've recently install FSharp 1.9.2.9 using mono on Ubuntu 7.10.

All works fine :) ... except that readline doesn't work in fsi.exe console: I mean the arrow key on the keyboard produce the raw ascii value (no completion, no history, not even line edition) ... which is quite annoying. I've try the --readline option, but this doesn't change anything.

Anybody got this problem? any advice?

Thanks,
ludo

.

Try "fsi --no-gui". F# may look like a console tool but it runs a Windows Forms event loop to ensure you can do GUI things from the console.

Thanks everyone for the advices.

I found this little gem which solve elegantly my problem: ledit

On ubuntu,
install it with: sudo apt-get install ledit
use it with this command line: ledit fsi.exe

Note: ledit was design to work with ocaml (I think), but it works fine with fsi

Hi,

I've been using fsi through Emacs, and it worked quite well. I used the ocaml mode from Inria, which provides syntactic coloration and shortcuts for interactive mode. It's perfect (F# is not OCaml), but it's ok.

I also have a question: has anyone used fsi through ssh? I've installed libgdiplus and mono, but I get the following error message:
Unhandled Exception: System.TypeInitializationException: An exception was thrown by the type initializer for System.Windows.Forms.XplatUI ---> System.ArgumentNullException: Could not open display (X-Server required. Check you DISPLAY environment variab\
le)

I think that the System.Windows.Forms shouldn't be needed for fsi (since it's a console tool). Does anyone have a solution? Or should I edit fsi.fs, and compile fsi without this dependency?

The completion is provided by Windows Console and not by fsi.exe itself. I don't see any easy way to implement history other than starting fsi.exe from another process that provides history and interacts through the editor. I would suggest vim or emacs that feature such functionality in a well known way, achieving functionalities similar to those you have in Visual Studio (BTW, in emacs it is possible to modify some interactive mode or simply use M-x shell command and start the fsi from the shell.
