Users need to parse delimited strings (CSV, tags, paths) into arrays for iteration or JSON output without external processing. Impact: New RainerScript function available to all users. Before: No native way to split strings into arrays in RainerScript. After: split(string, separator) returns a JSON array of substrings. Technical overview: Implements doFunct_split() in grammar/rainerscript.c Registers "split" in scriptFunct table with 2 required args Adds CNFFUNC_SPLIT enum in rainerscript.h Uses unified strstr-based iteration for all separator lengths Handles edge cases: empty input, leading/trailing/consecutive delimiters Includes error handling for json-c memory allocation failures Returns empty JSON array on null/empty input or separator Includes documentation (rs-split.rst) and test scripts
