How to print a message

Feb-03-15 13:47:42

I just want to output some text when something occurs.
I suppose it should go to the "Message Browser" in OMEdit.

I tried with the following code:

Code:

model msg

  Real x, y;

equation

  x = time;

  when time > 0.5 then

    print("message");

    y = time;

  end when;

end msg;

It should print at t=0.5, but I don't see any message (unless I watch the wrong place"!)

Thank anyone that wants to help.

You can use print or this:
https://build.openmodelica.org/Document … print.html

print seems to work fine: (see messages="message")

Code:


adrpo@ida-liu050 ~/dev/OpenModelica/build/bin/

$ cat > msg.mo

model msg 

  Real x, y; 

equation 

  x = time; 

  when time > 0.5 then 

    print("message"); 

    y = time; 

  end when; 

end msg; 



adrpo@ida-liu050 ~/dev/OpenModelica/build/bin/

$ cat > msg.mos

loadFile("msg.mo"); getErrorString();

simulate(msg); getErrorString();



adrpo@ida-liu050 ~/dev/OpenModelica/build/bin/

$ ../omc msg.mos

true

""

record SimulationResult

    resultFile = "c:/bin/cygwin/home/adrpo/dev/OpenModelica/build/bin/msg_res.mat",

    simulationOptions = "startTime = 0.0, stopTime = 1.0, numberOfIntervals = 500, tolerance = 1e-006, method = 'dassl', fileNamePrefix = 'msg', options = '', outputFormat = 'mat', variableFilter = '.*', cflags = '', simflags = ''",

    messages = "message",

    timeFrontend = 0.02278212030280691,

    timeBackend = 0.008754299484735505,

    timeSimCode = 0.001498251334356035,

    timeTemplates = 0.04028148031235384,

    timeCompile = 3.071980736768558,

    timeSimulation = 0.1831265795253099,

    timeTotal = 3.329325806147373

end SimulationResult;

The message will show up in the simulation output window and not in Messages Browser.

print() is sent to stdout directly and thus messes up the OMEdit output parsing. https://build.openmodelica.org/Document … print.html should work as expected. But it also does not. Seems we send it directly to stdout current/sad

I could replicate the suggestion from adrpo involving OMShell, and worked as expected.

As sioelund mentions, things seem not to be as good in OMEdit.

I tried both
...
print("message");
...
and
Modelica.Utilities.Streams.print("message");

but I could not see "message" in the simulation output window of OMEdit.

The coming nightly build should handle Streams.print correctly, but not the OpenModelica print extension

I checked today (with r24422) and saw
Modelica.Utilities.Streams.print("message");
working as expected also in OMEdit.

Thanks again!
