: Syntax
Experimentally 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
: Range#to_ary
Added. You can now do something like this:
a, b, c = 1..3
: break and next
Extended to take an optional expression, which is used as a value
for termination. [experimental]
: SHA1 module
ruby-sha1 1.2 is newly imported as a standard library, which shares
a common interface with the existing md5 module.
: MD5#<<
Added as an alias for MD5#update.
: 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]
: Line-range operation
Obsoleted except the case when used in a one-liner (ruby -e "..."),
which means "if 101..200" in a script is no longer interpreted as
comparison between (({$.})) and 101 or 200.
: Comparison of exception classes in a rescue clause
Changed to use ((<Module>))#=== for comparing $! with the exception
class specified in each rescue clause.
As the previous behavior was to use kind_of?, the effect is limited
to the SystemCallError case. SystemCallError.=== has been newly
defined to return true when the two have the same errno. With this
change, SystemCallError's with the same errno, such as Errno::EAGAIN
and Errno::EWOULDBLOCK, can both be rescued by listing just one of
them.
: ((<Array>))#fetch
Added.
: ((<Array>))#insert(n, other, ...)
Added. ((<ruby-talk:14289>))
This is much the same as (({ary[n,0] = [other,...]})) except
returing self.
ary = [0,1,2,3]
ary[2, 0] = [4, 5, 6]
p ary
ary = [0,1,2,3]
ary.insert(2, 4, 5, 6)
p ary
: ((<Array>))#sort!
Changed to always return self without checking whether the sequence
of the elements was modified or not.
Beware that this behavior is not guaranteed to continue in the
future. Do not rely on its return value. ((<ruby-dev:12506>))$B!%(B
: ((<Dir>)).open
Changed to return what the block returns when a block is given, just
as ((<File>)).open does. (It always returned (({nil})) in 1.6 and
prior)
: ((<Dir>)).chdir
Extended to take a block.
: ((<Dir>)).glob
Made to support meta-character escaping by a backslash. Wildcards
and spaces may now be escaped using a backslash.
: ((<Enumerable>))#all?
: ((<Enumerable>))#any?
: ((<Enumerable>))#inject
Added.
: ((<File>)).lchmod
: ((<File>)).lchown
Added.
: ((<IO>)).for_fd
Added.
: ((<IO>)).read
Added. ((<ruby-talk:9460>))
: ((<Interrupt>))
Made a subclass of ((<SignalException>)). (It was a subclass of
Exception in 1.6 and prior)
: ((<MatchData>))#to_ary
Added for convenience of Regexp#match. ((<ruby-dev:12766>))
Previously we had to do:
foo, bar, baz = /(\w+?)\s+(\w+?)\s+(\w+)/.match("foo bar baz").to_a[1..-1]
p [foo, bar, baz]
But now can do:
_, foo, bar, baz = /(\w+?)\s+(\w+?)\s+(\w+)/.match("foo bar baz")
p [foo, bar, baz]
: ((<Math>)).acos(x)
: ((<Math>)).asin(x)
: ((<Math>)).atan(x)
: ((<Math>)).cosh(x)
: ((<Math>)).sinh(x)
: ((<Math>)).tanh(x)
: ((<Math>)).hypot(x,y)
Added.
: ((<Module>))#included
Added. This is a hook called after Module#append_feature.
: ((<Module>))#method_removed
: ((<Module>))#method_undefined
Added.
: ((<NoMethodError>))
Added. ((<ruby-dev:12763>))
: NotImplementError
Finally obsoleted. Use ((<NotImplementedError>)).
: ((<Object>))#singleton_method_removed
: ((<Object>))#singleton_method_undefined
Added.
: ((<Proc>))#==
Added.
: ((<Process>)).times
Moved from ((<Time>)).times. (Time.times still remains but emits a
warning)
: ((<Process::Status>))
Added. (({$?})) is now an instance of this class.
: ((<Process>)).waitall
Added.
: ((<Regexp>)).last_match(n)
Extended to take an optional argument.
: ((<Regexp>))#options
Added.
: ((<String>))#insert(n, other)
Added.
This is much the same as (({str[n, 0] = other})) except returing
self.
: ((<Symbol>)).all_symbols
Added. ((<ruby-dev:12921>))
: ((<Symbol>))#intern
Added.
: ((<SystemCallError>)).===
Added. (See the "Comparison of exception classes in a rescue clause"
paragraph above) ((<ruby-dev:12670>))
: ((<SystemExit>))#status
Added.
: ((<TCPSocket>)).new
: ((<TCPSocket>)).open
Extended to take an address and a port number for the local side in
optional 3rd and 4th arguments.
: ((<Time>))
Extended to accept a negative time_t. (Only when the platform
supports it)
p Time.at(-1)
=> Thu Jan 01 08:59:59 JST 1970
: ((<Time>))#to_a
: ((<Time>))#zone
Made to return "UTC" under gmtime. It used to return a platform
dependent value, typically "GMT", in 1.6 and prior.
To be investigated:

* io.c (set_stdin): preserve original stdin.
* io.c (set_outfile): preserve original stdout/stderr.
