stringify doesn't work ?

[massimosala]

Python 3.8.10
pyclibrary just installed with pip

---

Sample header file:

#define MP_STRINGIFY(A) #A
#define MICROPY_VERSION_MAJOR 1
#define MICROPY_VERSION_MINOR 20
#define MICROPY_VERSION_MICRO 0
#define MICROPY_VERSION_STRING MP_STRINGIFY(MICROPY_VERSION_MAJOR) "." MP_STRINGIFY(MICROPY_VERSION_MINOR) "." MP_STRINGIFY(MICROPY_VERSION_MICRO)

I process the file with

parser = CParser(filename)
parser.process_all()
print(parser.defs["values"])

The output is

{'MICROPY_VERSION_MAJOR': 1, 'MICROPY_VERSION_MINOR': 20, 'MICROPY_VERSION_MICRO': 0, 'MICROPY_VERSION_STRING': None}

Problem: MICROPY_VERSION_STRING isn't evaluated.

I tried also with this definition

#define MP_STRINGIFY(A) str(A)
#define str(A) #A

Please, can you help me to solve it?

Addendum

Parsing the file with MP_STRINGIFY, I get this warning

:1: SyntaxWarning: 'tuple' object is not callable; perhaps you missed a comma?

Is 1 the line number?
These are the first lines of the real file...

Second observation.
Looking at fnmacros I see

fnmacros {'str': ('#{}', [0]), 'MP_STRINGIFY': ('#{}', [0]), etc...
