Re: custom promises: use data from python list in mustache template

toyed around a bit...returning just json seems not to work very well

import os
import json
from cfengine import PromiseModule, ValidationError, Result


class MkSudoPermsModule(PromiseModule):
    def __init__(self):
        super().__init__("itsv_mk_sudo_perms_promise_module", "0.0.1")

    def validate_promise(self, promiser, attributes):
        pass

    def evaluate_promise(self, promiser, attributes):
        lst = ['jboss1', 'jboss2', 'jboss3']
        return json.dumps(lst)

        return Result.KEPT


if __name__ == "__main__":
    MkSudoPermsModule().start()
~

result:

not very promising *gg*
