I was staying on the sideline because I don't know what's idiomatic in
Perl, but Perl and Ruby share a lot in common (one could say Perl is the
grandfather of Ruby), and I do know very well what's idiomatic in Ruby.
In perl you can do $ENV{'USER'}, and:
while (my ($k, $v) = each %ENV) {
print "$k = $v\n";
}
Obviously it's idiomatic to use hashes this way [1].
It was a waste for Git::config_regexp to not do the sensible thing here.
You can do exactly the same in Ruby: ENV['USER']
ENV.each { |k, v| print "#{k} = #{v}\n" }
And the way I would parse these configurations in Ruby is something like:
c = `git config -l -z`.split("\0").map { |e| e.split("\n") }.to_h
c['sendemail.smtpserver']
And this just gave me an idea...
