ParseString2List

llParseString2List

Summary

Function: list llParseString2List( string src, list separators, list spacers );

0.0	Forced Delay
10.0	Energy

Returns a list that is src broken into a list of strings, discarding separators, keeping spacers, discards any null values generated.

• string	src	–	source string
• list	separators	–	separators to be discarded
• list	spacers	–	spacers to be kept

Caveats

Blank values in the list are discarded. If you want them (to keep the order of a list, for example) use llParseStringKeepNulls instead.

• Only the first 8 separators and first 8 spacers will be used any extras will be ignored.
• All separators and spacers must be strings, all other types will be ignored.
• Separators take precedent over spacers. The string is parsed from start to finish, each position is compared against the separators then spacers before moving onto the next position.
• Duplicates are ignored.
• All entries in the return are typed as string. Use explicit typecasting on llList2String to convert the values into other types. Do not rely upon the implicit typecasting of the other llList2* functions (as they typically return a default value).

Examples

<lsl>default {

   state_entry()
   {
       // This will say:
       // <A><crazy><fox><.><Saw><the><moon><.><.>
       string my_string = "A crazy fox.  Saw the moon..";
       list my_list = llParseString2List(my_string,[" "],["."]);
       llOwnerSay("<" + llDumpList2String(my_list,"><") + ">");
       
       // This will say:
       //  <A><crazy><fox><.><><><Saw><the><moon><.><><.><>
       my_list = llParseStringKeepNulls(my_string,[" "],["."]);
       llOwnerSay("<" + llDumpList2String(my_list,"><") + ">");
   }

}</lsl>

Useful Snippets

Examples of processing more than 8 spacers or separators:

•	ParseString2List	–	Functions exactly the same as llParseString2List and llParseStringKeepNulls.
•	separateWords	–	Functions exactly the same as llParseString2List unless you violate the preconditions. Appears to be correct at a glance.
