rtiddsgen language python "#include foo/bar" error

We are moving toward replacing the Python Connector with the Python API and our IDL files are also used with C++.   In our case rtiddsgen for python creates invalid python code, for example, in this snippet there is a missing ‘)’ at the end of the line with ‘sys.path.append’   and we also get the general error “NameError: name 'sys' is not defined ”. Details are provided below, please advise.

 

sys.path.append(os.path.join(os.path.dirname(sys.path[0]),  /Test_001/idls/foo/')

from bar import *

sys.path.pop()

 

Version:

rti_connext_dds-7.1.0

rtiddsgen version 4.1.0

 

python --version

Python 3.6.8

 

python3.10 --version

Python 3.10.8

 

 

Command line for running rtiddsgen :

 

rtiddsgen -language Python   -verbosity 3   -update typefiles -I /home/user/Test_001/otherIdls/  /home/user/idls/helloWorld.idl

 

Directory structure:

 

-Test_001

    --idls

        HellowWorld.idl

    -otherIdls

          -Foo

              Bar.idl

 

HelloWorld.idl:

 

#include "foo/bar.idl"

struct HelloWorld {

    string<128> msg;

};

 

Complete file generated:

 

from dataclasses import field

from typing import Union, Sequence, Optional

import rti.idl as idl

from enum import IntEnum

 

sys.path.append(os.path.join(os.path.dirname(sys.path[0]), 'Test_001/idls/foo/')

from bar import *

sys.path.pop()

 

@idl.struct(

    member_annotations = {

        'msg': [idl.bound(128)],

    }

)

class HelloWorld:

    msg: str = ""

Hi,
We are aware of the issue (CODEGENII-1847) and it will be fixed in the next release. The issue affects any IDL included with a path.

The workaround is to remove the path from the include file. If you change the rtiddsgen call to:
rtiddsgen -language Python   -verbosity 3   -update typefiles -I /home/user/Test_001/otherIdls/foo  /home/user/idls/helloWorld.idl

And the included idl to:

#include "bar.idl"

It should work
