[pygccxml-development] pygccxml querying

[Roman Y. <rom...@gm...>]

As I promised, I checked how the querying for declarations works.
Basically you can search for a declaration:
* using full name - "::x::y::z"
* using its name only - "z"

In the past, I choose this method to prevent confusions.

Pay attention, searching for "x::y::z" will not work and will raise an
exception.

I will update the documentation.

That's good to know, I indeed was expecting that form to work, but it
makes sense to exclude it.

Is there a way to match (part of) a declaration on by string? Say I want
all methods that have parameter types with some string S in them, where
I just want to match the declaration string.

Good.

mb = module_builder_t(...)
mb.global_ns.decls( lambda d: 'xyz' in d.decl_string )

Is this what you are looking for?

Sort of, but applied to arguments, e.g.

for mf in main_ns.member_functions(arg_types=lambda d: 'blah' in
d.decl_string):
    # do something with mf

But this doesn't seem to work...

try this:

def my_query( f ):
    for arg in f.arguments:
        if <<<your logic>>>( arg.type ):
             return True
    else:
        if <<<your logic>>>(  f.return_type  ):
            return True
        else:
            return False

decls = mb.global_ns( my_query )

HTH
