F# interactive in Emacs loops indefinitely about fsharp HOT 10 CLOSED

BTW the first few lines of the trace won't help, if anything it would be some endless looping at the end of a very long trace. you would have to somehow catch the trace from the fsharpi process, don't know how to do that.

OK. Not sure what else I can do to help.

Did you try

fsharpi --readline-

Notice the - after the flag

from fsharp.

With this I get

bash-3.2$ fsharpi --readline-

For help type #help;;

1+1;;
val it : int = 2

what's the best way to tell if a process should suppress an implementation of readline support when running on Mono? e.g. some method in Mono.Posix?

from fsharp.

--readline- solves the issue. Thanks a lot. Keep up the awesome work ;)

Turned off readline by default when running as background non-console process

Detected by comparing foreground/background colors are equal. If there is a better way send a pull request.

I think you want to probe the TERM variable to be "dumb" or not.

If the variable is not dumb, it means that you have editing capabilities.

from fsharp.

Thanks! Strangely it is "dumb" in Emacs and null when fsharpi is run from MonoDevelop.

System.Environment.GetEnvironmentVariable("TERM");;

val it : string = null

from fsharp.

If TERM is set, it means that you are running under a full fledged pseudo-terminal (Console.IsOutput/Input Redirected) will both be false. Once you have determined that you are on a pseudo-terminal, you can use TERM to determine the kind, dumb meaning "no terminal".
