== Stristr ==


Lists in LSL are among the most memory intensive types of data. Manipulation of lists even more memory intensive. When manipulating data that does not ''' ''NEED'' ''' to be typecast to a list it is far more efficient to use other methods. As with the below examples (these serve the same functions as those from your page without costing the earth).
I don't know what came over me but I totally rewrote Stristr. It makes a good example but it shouldn't be used as a user function. The programmer already knows at compile time if the string is going to be empty and if they want the before or after value. In most cases you won't be working with null strings and you will want the one string or the other but never will it change during execution. This means if you created a specialized function for each case, each function would be about 3 lines of code. It's better IMHO to inline three lines of code and cement understanding then to create a function to do it for you.

The [[llKey2Name]] function does have a limited use. It will '''NOT''' return the name of an agent who is not now or has not very recently been on the same region as the script and will '''NOT''' return the name of an agent who is offline. The [[dataserver]] event (and its companion functions) can help make this function far more reliable.

Stristr

I don't know what came over me but I totally rewrote Stristr. It makes a good example but it shouldn't be used as a user function. The programmer already knows at compile time if the string is going to be empty and if they want the before or after value. In most cases you won't be working with null strings and you will want the one string or the other but never will it change during execution. This means if you created a specialized function for each case, each function would be about 3 lines of code. It's better IMHO to inline three lines of code and cement understanding then to create a function to do it for you.

I also added comments. I removed the example and func_footnote because it was the wrong way to do existence checking. -- Strife (talk|contribs) 06:17, 31 May 2010 (UTC)
