This seems doable in principle by using the
Cython.Compiler.Visitor.TreeVisitor class. You'll have to figure out
what Cython AST nodes the things you're looking for correspond to. As
a simple example, this will find all non-def functions in a Cython
file:
from Cython.Compiler import TreeFragment, Visitor
cython_code = unicode(open("filename.pyx").read())
class CdefFunFinder(Visitor.TreeVisitor):
def visit_Node(self, node):
self.visitchildren(node)
def visit_CFuncDefNode(self, node):
self.visitchildren(node)
print self.dump_node(node)
CdefFunFinder().visit(TreeFragment.parse_from_strings('<test>',
unicode(cython_code)))
