Changes for version 0.009

  • Yet another alpha release. Here are the usual lists: New features/API changes:
  • Added numeric overloading to JE::Null.
  • Added compile as an alias for parse.
  • Added the 'exists' and 'class' methods to JE::Number Fixes:
  • JE::LValue's overloading was very buggy with anything other than simple conversion. I've fixed it and written a test script.
  • Corrected the bitshift operators such that numbers > 31 for the right operand now have % 32 applied, and are no longer simply treated as 31.
  • Corrected JE::Null->to_boolean so it returns a JE::Boolean, not a JE::String.
  • Stopped surrogate escape sequences in string literals from producing warnings.
  • Corrected JE::Number's stringification overloading to match the stringification in JavaScript (for NaN and Infinity)
  • A JE::Number that has a value of NaN now boolifies in Perl as false, as in JavaScript.
  • Fixed the constructors for the various subclasses of Error, so that they no longer throw TypeErrors when called ('new TypeError' would actually cause the whole script to die)
  • Corrected 'instanceof' so it throws an error if its right operand is an object but not a function
  • Corrected the 'prototype' properties of the various sub- classes of Error such that they now actually inherit from Error.prototype instead of directly from Object.prototype.
  • Fixed the << operator so it now works correctly on 64-bit machines
