Parse text into an array of tokens or array of arrays
Description
The nested_quotewords() and quotewords() functions are two functions that accept a delimiter
and a list of lines and then breaks those lines up into a list of words ignoring delimiters
that appear inside quotes. quotewords() returns all of the tokens in a single long list,
while nested_quotewords() returns a list of token lists corresponding to the elements of
@lines. parse_line() does tokenizing on a single string. The quotewords() functions simply
call &parse_line(), so if you're only splitting one line you can call parse_line() directly
and save a function call.
