Changes for version 0.006

  • Alpha release.
  • Added TypeError and RangeError classes
  • Finished the Function and Array classes (except for Function.prototype.toString)
  • JE::String now has an exportable 'surrogify' function
  • Added some methods (toString, valueOf, charAt, charCodeAt, concat, indexOf, lastIndexOf, localeCompare) to String objects, and added the String constructor to the global object
  • Found and fixed quite a few bugs in the parser: o || && were parsing as | | and & & o Hexadecimal literals would cause syntax errors o The parser would create a garbage tree when certain infix ops were followed by compound expressions that could con- tain the same op (i.e., [], {}, () and function literals). (I fell into the 'sub foo { /regex(.*)/; foo(); print $1}' trap.) o Bracketed subscripts did not allow whitespace before the closing bracket o "a++\nb++" without a semicolon between the two statements was causing a syntax error because -- and ++ were gobbling up trailing whitespace. o <<= and >>= and >>>= were causing syntax errors o for loops with variable declarations in the header weren't parsing o continue/throw/break/return were not parsing correctly when followed by a line break o 'with' was parsing as 'while' (!) o switch and try blocks weren't parsing correctly
