Currently, git-repo-config will just return the raw value of option as specified in the config file; this makes things difficult for scripts calling it, especially if the value is supposed to be boolean. This patch makes it possible to ask git-repo-config to check if the option is of the given type (int or bool) and write out the value in its canonical form. If you do not pass --int or --bool, the behaviour stays unchanged and the raw value is emitted. This also incidentally fixes the segfault when option with no value is encountered. [jc: tweaked the option parsing a bit to make it easier to see that the patch does not change anything but the type stuff in the diff output. Also changed to avoid "foo ? : bar" construct. ] Signed-off-by: Petr Baudis <pasky@suse.cz> Signed-off-by: Junio C Hamano <junkio@cox.net>
