Context
Cef is a framework allowing us to embed chromium into our application
Golang is the language designed by Google employee with heavy support on concurrency.
I'm trying to translate some Cef code to Golang for binding ( because manually tranlsating them all are insane and less fun ).
Sample code
Its it rather easy to parse your C code using python
#cef_parser.py
from clang.cindex import Index
from pprint import pprint
from optparse import OptionParser, OptionGroup
def get_info(node):
children = [get_info(c) for c in node.get_children()]
return { 'id' : get_cursor_id(node),
'kind' : node.kind,
'usr' : node.get_usr(),
'spelling' : node.spelling,
'location' : node.location,
'extent.start' : node.extent.start,
'extent.end' : node.extent.end,
'is_definition' : node.is_definition(),
'definition id' : get_cursor_id(node.get_definition()),
'children' : children }
parser = OptionParser("usage: %prog [options] {filename} [clang-args*]")
parser.disable_interspersed_args()
(opts, args) = parser.parse_args()
index = Index.create()
tu = index.parse(None, args)
if not tu:
parser.error("unable to load input")
pprint(('nodes', get_info(tu.cursor)))
index.parse(None, args), is doing the heavy lifting task, args contain all the options require to help clang parsing our code.
For example:
python cef_parser.py main.h -I./included_header
This will allow clang to read main.h header file in ./inlcuded_header, then get_info(node) will dump the information in this particular node.
The properties in node is rather confusing if you read the source file, I compiled the reference for Python-Clang.
