This little PR suggests a
not:env var processor (in a perfect world, I would name it!:but only words are accepted as prefixes 🙃)Goal is to negate a boolean env variable.
Example usage:
I'm thinking of this for this kind of usages:
some_prod_related_stuff: '%env(not:APP_DEBUG)%'enabled: '%env(not:bool:key:disabled:query_string:SOME_DSN)%'Processor raises an exception when preceding resolved value is not a boolean.This processor allows any truthy/falsy values, like
bool:.Thank you,
Ben
