[MonoDevelop] F# addin

[Vasili I. Galchin]

Lluis,

   I think I understand your instructions. In any case, here is what I did:

1) I started MonoDevelop 2.2.2 via "make run"

2) I selected F# console project ..... "Console1"

3) A rudimentary F# console project script was created

4) I did a "Build All" whereupon monodevelop was hung.

5) Based on LoggingService:LogInfos I added to
FSharpBindingCompilerManager.cs in particular "DoCompilation" method:

                        pinfo.UseShellExecute = false;
                        pinfo.RedirectStandardOutput = true;
                        pinfo.RedirectStandardError = true;

LoggingService.LogInfo("KICK OFF FSC!!");  // WNH

                        MonoDevelop.Core.Execution.ProcessWrapper pw =
Runtime.ProcessService.StartProcess (pinfo, outwr, errwr, null);
LoggingService.LogInfo("Kicked off!");  // WNH     <<<<<< get this LogInfo!!!!
                        pw.WaitForOutput();
LoggingService.LogInfo("after wait!");  // WNH     <<<<<< never get
this LogInfo!!
                        int exitCode = pw.ExitCode;
                        outwr.Close();
                        errwr.Close();
                        pw.Dispose ();
                        return exitCode;

I can pretty conclusively infer that the "fsc" never sends "process
exit" event. Hence we are waiting indefinitively on the
pw.WaitForOutput()!!!

I did "pid" checking at this point:

vasili at Komputer:/usr/bin$ ps -aef | grep fsc
vasili    2684  1683  0 19:25 pts/2    00:00:00 grep --color=auto fsc
 <<<< NO FSC PROCESS
vasili at Komputer:/usr/bin$ fsc    <<< RUN FSC WHILE MONODEVELOP IS
HUNG!!! MonoDevelop UNHANGS when fsc is run from kubuntu shell
instance!!
Microsoft (R) F# 2.0 Compiler build 1.9.9.9

error FS0207: No inputs specified
vasili at Komputer:/usr/bin$ ps -aef | grep fsc
vasili    2690  1683  0 19:26 pts/2    00:00:00 grep --color=auto fsc
vasili@

So Lluis this seems 1) no fsc process hanging around when monodevelop
is hung 2) only running a fsc instance from shell instance unhangs
MonoDevelop instance. Any ideas??

I think you will agree I have spent time reading MonoDevelop code
including "core" code to get where I am now.

Vasili
