how to use local variable in check block?

[hh9527]

_RE = r"[a-z]+"
schema App:
    config: {str:str} = {}

    check:
        invalid = [k for k, v in config if not regex.match(k, RE)]
        len(invalid) == 0, "key format errors: {}".format(invalid)

kcl report: name 'invalid' is not defined

Have you tried define the invalid variable in the schema block? It works well for me. Currently, the check block only allows logic expressions defined there.

import regex

RE = r"[a-z]+"
schema App:
    config: {str:str} = {}

    _invalid = [k for k, v in config if not regex.match(k, RE)]
    check:   
        len(_invalid) == 0, "key format errors: {}".format(_invalid)
