Parsing functions for TOON format elements.

This module provides functions to parse array headers, keys, values, and delimited data from TOON format strings. Parse a primitive token (string, number, boolean, or null).

Quoted strings remain strings even if they look like numbers. Parse a quoted string token. Parse an unquoted value (number or string). Parse a numeric token. Check if a string has a forbidden leading zero. Parse delimited values from a string.

Splits on the delimiter while respecting quoted sections. Split a string on delimiter, respecting quotes. Parse a key from the beginning of a line.

Returns the key and the position after the colon. Parse a quoted key. Parse an unquoted key. Parse an array header line.

Returns the header info and any inline values after the colon. Parse the bracket segment [#?N delim?] Parse length and delimiter from bracket content. Parse fields segment {field1,field2,…} Unescape field names (handle quoted field names). Extract inline values after the colon. Check if a line looks like an array header. Check if content is a key-value line (has unquoted colon).
