From 95b567c7c3cf6b85d74b79424cdfbd40a7dee7c9 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Wed, 18 Jun 2014 15:48:29 -0400 Subject: use skip_prefix to avoid repeating strings It's a common idiom to match a prefix and then skip past it with strlen, like: if (starts_with(foo, "bar")) foo += strlen("bar"); This avoids magic numbers, but means we have to repeat the string (and there is no compiler check that we didn't make a typo in one of the strings). We can use skip_prefix to handle this case without repeating ourselves.
