code-generator's Issues

error running generated python code

I had run ./build.sh and here is the output.
Building configurations...
Running action 'gmake'...
Generating Makefile...
Generating codegen.make...
Done.

Linking codegen

I got a test.py file in src/

When I launch test.py, I am getting below error.
python test.py
Traceback (most recent call last):
File "test.py", line 1, in
import CodegenExample
ImportError: No module named CodegenExample

there is no so file generated or atleast the step is missing.
can you tell what did I missed?

I am very much interested in this automatic python generator and would like to apply this onto a large c++ library. I should also mention there is a heavy use of template in the target library.

extending dump_ast

I wanted to extend dump_ast to print out the names and types of the arguments to functions.

For example, consider the following test.h file:

SomeType foo (AnotherType a, AnotherType b);

Lets suppose SomeType and AnotherType could be defined in another header file.

Currently running dump_ast.h returns the following:

./dump_ast.py test.h 
TRANSLATION_UNIT test.h
  +--TYPEDEF_DECL __int128_t
  +--TYPEDEF_DECL __uint128_t
  +--TYPEDEF_DECL __builtin_va_list
  |  +--TYPE_REF __va_list_tag
  +--FUNCTION_DECL foo

There is no real useful information about foo here, I would like to know that it receives two parameters named a and b of type AnotherType, and that it returns a parameter of SomeType. I would like to think this should be possible using the clang api, unfortunately I haven't been able to do this.

By using the get_arguments() (as opposed to only get_children()) I am able to get the names of the input parameters of a function, but I can't get the names of their types. Suggestions?
