specifies if symbols are case sensitive (the default is false).
specifies if characters are reported by setting token = ch or as G_TOKEN_CHAR (the default is true).
specifies the characters at the start and end of single-line comments. The default is "#\n" which means that single-line comments start with a '#' and continue until a '\n' (end of line).
specifies the characters which can start identifiers (the default is G_CSET_a_2_z, "_", and G_CSET_A_2_Z).
specifies the characters which can be used in identifiers, after the first character (the default is G_CSET_a_2_z, "_0123456789", G_CSET_A_2_Z, G_CSET_LATINS, G_CSET_LATINC).
specifies which characters should be skipped by the scanner (the default is the whitespace characters: space, tab, carriage-return and line-feed).
specifies if identifiers are reported as strings (the default is false).
specifies if all numbers are reported as G_TOKEN_FLOAT (the default is false).
specifies if binary, octal and hexadecimal numbers are reported as G_TOKEN_INT (the default is true).
specifies if binary numbers are recognized (the default is false).
specifies if multi-line comments are recognized (the default is true).
specifies if floating point numbers are recognized (the default is true).
specifies if hexadecimal numbers are recognized (the default is true).
specifies if '$' is recognized as a prefix for hexadecimal numbers (the default is false).
specifies if identifiers are recognized (the default is true).
specifies if single-character identifiers are recognized (the default is false).
specifies if null is reported as G_TOKEN_IDENTIFIER_NULL (the default is false).
specifies if octal numbers are recognized (the default is true).
specifies if strings can be enclosed in double quotes (the default is true).
specifies if strings can be enclosed in single quotes (the default is true).
specifies if symbols are recognized (the default is true).
specifies if a symbol is searched for in the default scope in addition to the current scope (the default is false).
specifies if multi-line comments are skipped and not returned as tokens (the default is true).
specifies if single-line comments are skipped and not returned as tokens (the default is true).
use value.v_int64 rather than v_int
specifies if symbols are reported by setting token = v_symbol or as G_TOKEN_SYMBOL (the default is false).
Specifies the #GScanner parser configuration. Most settings can be changed during the parsing phase and will affect the lexical parsing of the next unpeeked token.
