pub fn command_env(
env: &dyn Fn(&str) -> Option<String>,
) -> Vec<(String, String)>Expand description
The variables a command of a Spec Kit project gets: the override, set
to the installed specify’s own interpreter when it imports PyYAML.
env looks up the command’s environment (its PATH finds specify);
nothing when the person set the override or its predecessor, or when
no such interpreter is found.
