In other hand, they can no longer access to - variables defined in eval. - -: negative number literals - - Digits preceded minus sign is a literal integer. - -: array expansion - - Fixed with the following behavior: - - a = *[1] - p a #=> [1] - - Now 1-element array in rhs is expanded properly. - - a = *[1] - p a #=> 1 - -: break and next - - Extended to take an optional expression, which is used as a value - for termination. - -: direct assignment to Foo::Bar is allowed - - also, you can define "class Foo::Bar; end". - -= language core - -: $stdin, $stdout, $stderr - - can be assignable again. the original stdio are preserved as STDIN, - STDOUT, STDERR. - -: $VERBOSE now has 3 levels - - nil - silence, false - medium (default), true - verbose - -: allocation framework - - any instance of class can be allocated by class.allocate, - (except for a few classes). - -: comparison of exception classes in a rescue clause - - changed to use Module#=== for comparing $! with the exception - class specified in each rescue clause. - - as the previous behavior was to use kind_of?, the effect is limited - to the SystemCallError case. SystemCallError.=== has been newly - defined to return true when the two have the same errno. With this - change, SystemCallError's with the same errno, such as Errno::EAGAIN - and Errno::EWOULDBLOCK, can both be rescued by listing just one of - them. - -: constants lookup - - improved at the performance of searching by using an internal hash - table. - - calls const_missing method of the class/module, if constant is not - found in the look up path. - -: expression parenthesis in the first argument - - altered to get the following code (note the space after p): - - p ("xx"*2).to_i - - Interpreted as: - - p (("xx"*2).to_i) - - Instead of: - - (p("xx"*2)).to_i - -: implicit comparison in conditional expressions - - Obsoleted except when it is used in -e. - - : between Range and $. - Use explicit comparison instead. - - : between Regexp and $_ - Use the unary method ~/re/ instead. - -: to_str - - added to get objects which define to_str() treated as String's. - - now almost all the built-in methods try each argument with to_str() - when they expect it to be a String. - - foo = Object.new - class <<foo - def to_str - "foo" - end - end - p File.open(foo) - => -:7:in `open': wrong argument type Object (expected String) (TypeError) - ruby 1.6.4 (2001-04-19) [i586-linux] - => -:7:in `open': No such file or directory - "foo" (Errno::ENOENT) - ruby 1.7.0 (2001-05-02) [i586-linux] - -: multiple assignment behavior - - Fixed so that "*a = nil" results in "a == []". - -= changes in core class library - -: open - - Extended so that when the third argument is permission flags it - calls open(2) instead of fopen(3). - -: sprintf - - new format specifier "%p" is available. - -: lambda and proc - - Proc object returns from these methods has the following attributes: - - * strict argument number check - * break and return terminates the proc execution. - -: warn(message) - - a method to give warnings. - -: abort() - - takes optional terminate message argument. - -: Object#initialize_copy - - copy constructor for clone and dup. - -: Object#instance_variable_set, Object#instance_variable_get - - added. - -: Object#singleton_method_removed -: Object#singleton_method_undefined - - Added. - -: Array#transpose - - added. - -: Array#fetch(index [, default]) - - Added.

Do not rely on its return value. [ruby-dev:12506] - -: Array#filter - - Previously deprecated, now removed. Use Array#collect!. - -: Array#pack, String#unpack - - Allows comment in template strings. - -: Array#pack, String#unpack - - New templates 'q' and 'Q' for 64bit integer (signed and unsigned respectively). - -: Array#new - - Now takes block to fill initial values.

It used to return a platform - dependent value, typically "GMT", in 1.6 and prior. - -: Marshal to use marshal_dump and marshal_load - - if a dumping object responds to 'marshal_dump', Marshal.dump calls - it, and dumps object returned.
