| 91 " This is a bit more complicated, because function arguments can be passed in a | |
| 92 " very similar form on how attribute sets are defined and two regions with the | |
| 93 " same start patterns will shadow each other. Instead of a region we could use a | |
| 94 " match on {\_.\{-\}}, which unfortunately doesn't take nesting into account. | |
| 95 " | |
| 96 " So what we do instead is that we look forward until we are sure that it's a | |
| 97 " function argument. Unfortunately, we need to catch comments and both vertical | |
| 98 " and horizontal white space, which the following regex should hopefully do: | |
| 99 " | |
| 100 " "\%(\s\|#.\{-\}\n\|\n\|/\*\_.\{-\}\*/\)*" | |
| 101 " | |
| 102 " It is also used throught the whole file and is marked with 'v's as well. | |
| 103 " | |
| 104 " Fortunately the matching rules for function arguments are much simpler than | |
| 105 " for real attribute sets, because we can stop when we hit the first ellipsis or | |
| 106 " default value operator, but we also need to paste the "whitespace & comments | |
| 107 " eating" regex all over the place (marked with 'v's): | |
| 108 " | |
