  • Skip any whitespace characters.
    • - *
  • If a numeric character is encountered, attempt to parse a numeric - * value. Leading '-' characters indicate a numeric only if followed by - * another non-'-' numeric. The value of the numeric token is terminated - * by either the first non-numeric encountered, or the second occurrence of - * '-' or '.'. The token type returned is TT_NUMBER and nval - * is set to the value parsed.
    • - *
  • If an alphabetic character is parsed, all subsequent characters - * are read until the first non-alphabetic or non-numeric character is - * encountered. The token type returned is TT_WORD and the value parsed - * is stored in sval. If lower case mode is set, the token - * stored in sval is converted to lower case.

Any character with a - * non-alphabetic and non-numeric attribute (such as white space, a quote, - * or a commet) are treated as non-alphabetic and terminate the word.
    • - *
  • If a comment character is parsed, then all remaining characters on - * the current line are skipped and another token is parsed. Any EOL or - * EOF's encountered are not discarded, but rather terminate the comment.
    • - *
  • If a quote character is parsed, then all characters up to the - * second occurrence of the same quote character are parsed into a - * String. This String is stored as - * sval, but is not converted to lower case, even if lower case - * mode is enabled. The token type returned is the value of the quote - * character encountered. Any escape sequences - * (\b (backspace), \t (HTAB), \n (linefeed), \f (form feed), \r - * (carriage return), \" (double quote), \' (single quote), \\ - * (backslash), \XXX (octal esacpe)) are converted to the appropriate - * char values. Invalid esacape sequences are left in untranslated. - * Unicode characters like ('\ u0000') are not recognized.
    • - *
  • If the C++ comment sequence "//" is encountered, and the parser - * is configured to handle that sequence, then the remainder of the line - * is skipped and another token is read exactly as if a character with - * the comment attribute was encountered.
    • - *
  • If the C comment sequence "/*" is encountered, and the parser - * is configured to handle that sequence, then all characters up to and - * including the comment terminator sequence are discarded and another - * token is parsed.
