TypeError: _generate_type() got an unexpected keyword argument 'emit_declname'

I am using pycparserext to parse, edit and then re-generate OpenCL kernels. During the re-generation phase, with some kernels, I get the following error:

File "<path>/test.py", line 131, in instrument_file
    f.write(gen.visit(ast))
File "<path>/env/lib/python3.7/site-packages/pycparser/c_generator.py", line 28, in visit
    return getattr(self, method, self.generic_visit)(node)
File "<path>/env/lib/python3.7/site-packages/pycparserext/ext_c_generator.py", line 155, in visit_FileAST
    s += self.visit(ext)
File "<path>/env/lib/python3.7/site-packages/pycparser/c_generator.py", line 28, in visit
    return getattr(self, method, self.generic_visit)(node)

... (long list of calls here) ...

File "<path>/env/lib/python3.7/site-packages/pycparser/c_generator.py", line 122, in visit_Cast
    s = '(' + self._generate_type(n.to_type, emit_declname=False) + ')'
TypeError: _generate_type() got an unexpected keyword argument 'emit_declname'

This error happens only when a call to visit_Cast occurs somewhere along the way. Whats more, the only place where pycparserext is being used (and not pycparser) seems to be the second call in the trace above. Note that gen comes from pycparserext. From somewhere near the start of my script:

from pycparserext.ext_c_generator import OpenCLCGenerator
...
gen = OpenCLCGenerator()

It seems to me that your _generate_type() is called and not the one from pycparser, despite the fact that the trace says otherwise, given that it is the implementation of _generate_type() from pycparserext (and not from pycparser) that does not have the keyword argument emit_declname.

I downgraded pycparser from version 2.20 to 2.19 and it worked. Problem is that the version of pycparserext that is available from pip does not forbid version 2.20 of pycparser, something that you have added in your latest commit.

Please feel free to leave the issue open or close it.

Released 2020.1 to the package index that includes the version hint on pycparser. I'll leave this open since, at some point, the incompatibility with 2.20 will need to get resolved.
