new_struct events not firing in file parser

[Rakaneth]

I'm using Python 3.7.2 and trying to use the file parser (I am porting from a C++ version of the same game and already have data files written in that format). I have defined my custom listener:

class CreatureParser:
    def __init__(self):
        self.temp = CreatureTemplate()

    def new_struct(self, struct, name):
        if tcod.struct_get_name(struct) == 'creature':
            print(f'New creature: {name}')
            self.temp = CreatureTemplate()
        return True

    def new_flag(self, name):
        return True

    def new_property(self, name, typ, value):
        stat_names = ['str', 'stam', 'spd', 'skl', 'sag', 'smt']
        if name == 'name':
            self.temp.name = value
        elif name == 'type':
            self.temp.type = value
        elif name == 'desc':
            self.temp.desc = value
        elif name == 'unarmed':
            self.temp.unarmed = value
        elif name == 'glyph':
            self.temp.glyph = value
        elif name in stat_names:
            self.temp.stats[name] = value
        elif name == 'col':
            self.temp.color = value
        elif name == 'tags':
            self.temp.tags = value
        elif name == 'startItems':
            self.temp.start_tems = value
        return True

    def end_struct(self, struct, name):
        CREATURE_TEMPLATES[name] = self.temp
        return True

    def error(self, msg):
        print(f'Error parsing creature file: {msg}')
        return False

My data file looks like this:

creature "wolf" {
	name="wolf"
	type="wolf"
	desc="A large, grey wolf."
	unarmed="fangs"
	glyph='W'
	col="127,101,63"
	stats {
		spd=15
		str=15
		vision=10
	}
	tags=["animal", "wolf"]
}

creature "zombie" {
	name="zombie"
	type="undead"
	desc="Once a man, now a shambling zombie."
	unarmed="hands"
	glyph='U'
	stats {
		str=20
		skl=5
		vision=4
	}
	tags=["undead"]
}

The new_struct function is not getting called, though everything else is.

I fixed this in my local copy by updating line 2523 in libtcodpy.py:

def _pycall_parser_new_struct(struct, name):
    return _parser_listener.end_struct(struct, _unpack_char_p(name))

I updated this to:

def _pycall_parser_new_struct(struct, name):
    return _parser_listener.new_struct(struct, _unpack_char_p(name))

Sorry for that. The parser rarely gets used from Python. I'll deploy a fix today.

Indeed - like I said, I've got data files from a C++ version of the game and it's about as much effort writing the parsers as it is to convert the data files to something suitable in Python.
