How to exclude datas from dependencies

[azmeuk]

My application embeds babel and pycountry. Those dependencies are some of the heaviest in my pyinstaller build, as they come with a lot of string catalogs for languages my application does not support.
I would like to gain some space by excluding useless language catalogs.

How can I achieve this?

By removing them manually.

Or, you can filter the Analysis.datas list in the .spec file, before it is passed on to other build targets.

Thanks, I could filter files with this:

codes = ["en", "fr", "es", "de"]

def filter_babel_catalogs(item):
    dest, _, _ = item
    if not re.match(r"babel/locale-data/\w+\.dat", dest):
        return True

    code = Path(dest).stem[:2]
    return code in codes


def filter_pycountry_catalogs(item):
    dest, _, _ = item
    if not re.match(r"pycountry/locales/\w+/LC_MESSAGES/.+\.mo", dest):
        return True

    code = dest.split("/")[2][:2]
    return code in codes


def filter_faker_providers(item):
    dest, _, _ = item
    if not re.match(r"faker/providers/\w+/\w+", dest):
        return True

    code = dest.split("/")[3][:2]
    return code in codes

a.datas = list(filter(filter_babel_catalogs, a.datas))
a.datas = list(filter(filter_pycountry_catalogs, a.datas))
a.datas = list(filter(filter_faker_providers, a.datas))
