Parse - Function Summary
Parses a series according to rules.
parse input rules
input - Input series to parse (must be: series)
rules - Rules to parse by (must be: block string none)
/all - Parses all chars including spaces.
/case - Uses case-sensitive comparison.
Parsing provides a means of recognizing a series of characters that appear in a particular order. Essentially, it is a method of finding and matching patterns. The rules argument supplies a block of grammar productions that are to be matched.
There is also a simple parse mode that does not require rules, but takes a string of characters to use for splitting up the input string.
Parse also works in conjunction with bitsets (charset) to specify groups of special characters.
The result returned from a simple parse is a block of values. For rule-based parses, it returns TRUE if the parse succeeded through the end of the input string.
The /ALL refinement indicates that all the characters within a string will be parsed. Otherwise, spaces, tabs, newlines, and other non-printable characters will be treated as spaces.
The /CASE refinement specifies that a string is to be parsed case sensitive.
trim - Removes whitespace from a string. Default removes from head and tail.
