I don't know what kinds of variables you want to set exactly, but another possible option here is some mechanism to point Git to an extra config file. This would work if you are setting a bunch of options in some static way, but not if you're setting them to custom values for each command invocation (because then you'd be dealing with a temp file, which is annoying and error-prone). I'm thinking something like a $GIT_CONFIG_ENV_FILE that is parsed after repo config but before $GIT_CONFIG_PARAMETERS. Or alternatively, add an includeIf directive that lets you do something like: [includeIf "env:FOO"] path = foo.gitconfig which triggers if $FOO is set. But again, that's only useful if you have certain "profiles" of config you're trying to set, and not custom values. -Peff
