case-insensitive tests and lists

[Innula Zenovka]

What's the best way of testing

 

list source;
string test;
	if(~llListFindList(source,[test])){
		//test is in the list
	}

 without needing to worry about inconsistent upper- and lower-case letters (which drove me almost to tears yesterday before I realised that was why things weren't working right)?

So far I've come up with

 

	if(~llSubStringIndex((llToLower((string)source),llToLower(test))){

	} 

but I'm wondering if there is a better way.   There usually is.

What I do is only a variation of what you are doing....  when I load my list, if I know I have to do some comparisons on certain entries, I try to force the entry in the list to be lower case using llToLower.  Then, I usually will compare with a hardcoded lowercase string.  Essentially, the reverse of what you are doing.  Also, I will do an extra step of removing whitespace from the beginning and end of the word before I put it into the list.

well if you just need a generic find and not an index returned, what you're doing isn't bad, although you may want to use llDumpString2List with an unlikely seperator instead of (string)casts that may crossmatch 2 entries... \t and \n work good for name data... other than that... yeah, that's about as good as you can get for case insensitive.

although depending on the data, you could instead populate the list with lowercased version, and test with a lower cased version.... saving you a little on runtime load, but not so good if you need the stored data to be mixed case.

the second sentence was covered by andromeda, sorry for duplication
