Hi, I'm working with a proprietary programming language which ignores case. I now started to write a custom version of diff.*.xfuncname and it is kind of ugly to always spell out all cases like [Ff][Uu][Nn][cC][Tt][Ii][oO][Nn]. I've seen that the builtin diff patterns in userdiff.c can be specified ignoring case using the IPATTERN macro. One of the possible solutions would be to patch userdiff.c (patch courtesy of Johannes Schindelin): -- snip -- diff --git a/userdiff.c b/userdiff.c index fad52d6..f089e50 100644 --- a/userdiff.c +++ b/userdiff.c @@ -228,6 +228,9 @@ int userdiff_config(const char *k, const char *v) return parse_funcname(&drv->funcname, k, v, 0); if (!strcmp(type, "xfuncname")) return parse_funcname(&drv->funcname, k, v, REG_EXTENDED); + if (!strcmp(type, "ixfuncname")) + return parse_funcname(&drv->funcname, k, v, + REG_EXTENDED | REG_ICASE); if (!strcmp(type, "binary")) return parse_tristate(&drv->binary, k, v); if (!strcmp(type, "command")) -- snap - With a patch like that I would, of course, supply documentation and tests. Is that something worth a try from my side? An alternative solution would be to add something like pxfuncname which understands PCREs which we we already support in git grep. And yet another alternative would be that I send a patch enhancing userdiff.c with a reasonable pattern for the programming language. But its community, and especially intersected with git users, is not that large.
