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.
