For what it's worth my idea of hacking a plumbing thingy for
git-send-email here before ultimately deciding that my simpler caching
approach was easier and gave me 95% of the win, was to just teach it a
mode where it spews out all config variables \0-delimited with all
possible interpretations of it. I.e.:
some.variable 123 bool true path 123 string 123 [...]
It's rather cheap to do the "interpret this as --type=X for me" on the
C-level, so we might as well spew out all possible interpretations.
That means that any external tool would be guaranteed to only need one
"git config" invocation to parse any of its config, i.e. in a case where
variable X decides if variable Y is a bool or path or whatever. They'd
already have all possible values.
Something like:
git config -l -z --type=bool,path
git config -l -z --type=ALL
