getErrorString raises pyparsing.ParseException after calling buildModel in the python interface

[robert.mueller@…]

Hello,

to retrieve information about the translation process, we need to call getErrorString() after calling buildModel().

In the OMSHell this works just fine by executing buildModel(Modelica.Blocks.Examples.PID_Controller);getErrorString()

Using the python interface (v1.13.0-dev-1098-ge7d386dfb (64-bit)), the following minimal working example leads to pyparsing.ParseException: Expected end of text (at char 123), (line:2, col:1):

import sys

sys.path.insert(0, r'C:\OpenModelica1.13.0-dev-64bit\share\omc\scripts\PythonInterface')
sys.path.insert(0, r'C:\OpenModelica1.13.0-dev-64bit\lib\python')

import omniORB
import OMPython

interface = OMPython.OMCSession()
print(interface.sendExpression("buildModel(Modelica.Blocks.Examples.PID_Controller);getErrorString()"))

If I instead send the command print(interface.sendExpression("buildModel(Modelica.Blocks.Examples.PID_Controller);getErrorString()")) (added a semicolon after getErrorString(), I get pyparsing.ParseException: Expected {quoted string, starting with " ending with " | Combine:({["-"] {"0" | W:(1234...,0123...)} [{"." W:(0123...)}] [{W:(eE) W:(0123...,0123...)}]}) | Forward: ... | Group:({Suppress:("{") [Forward: ... [, Forward: ...]...] Suppress:("}")}) | Group:({Suppress:("(") [Forward: ... [, Forward: ...]...] Suppress:(")")}) | {Suppress:("SOME") Suppress:("(") Forward: ... Suppress:(")")} | "true" | "false" | {"NONE" Suppress:("(") Suppress:(")")} | Combine:(Forward: ...)} (at char 0), (line:1, col:1) instead.

Is this reproducible? Any tips or workarounds are welcome, thank you!

I thought you don't need to call getErrorString in the python interface, it will be called automatically after each API command.

[robert.mueller@…]

That would be great! But I don't know how to access the error string. If I just call interface.sendExpression("buildModel(Modelica.Blocks.Examples.PID_Controller)"), it only returns the tuple ('C:/tmp/Modelica.Blocks.Examples.PID_Controller', 'Modelica.Blocks.Examples.PID_Controller_init.xml').
Or am I missing the obvious here?

I imagine there is not a lot of time for fixing minor issues like this with the 1.14 release, but is there at least a known workaround? thank you for looking into it! :)

We can give it a try
