This file contains invisible Unicode characters

This file contains invisible Unicode characters that are indistinguishable to humans but may be processed differently by a computer. If you think that this is intentional, you can safely ignore this warning. Use the Escape button to reveal them.

: Syslog module
Imported.
: String#chomp
if $/ == '\n', chops off last newlines (any of \n, \r, \r\n).
: IO#puts
do not treat Array specially.
: Module::new/Class::new
takes block.
: allocation framework
any instance of class can be allocated by class.allocate,
(except a few classes).
: String#[]
starting offset can be specified as optional second parameter.
: String/Array methods
returns an instance of receivers class.
: String::new
returns "".
: Dir#path
Added.
: Enum#sort_by
Added.
: Signal
new module, has module functions Signal::trap and Signal::list.
: Curses
Updated. New methods and constants for using the mouse, character
attributes, colors and key codes have been added.
: Range#step([step=1])
Added.
: Regexp
It is being obsoleted to regard /re/ as /re/ =~ $_ in a conditional
context. Use ~/re/ instead.
: String#lstrip, rstrip, lstrip!, rstrip!
Added. These strip only left or right part of a string.
: Socket::pack_sockaddr_in(), Socket::unpack_sockaddr_in()
Added. Utility for direct Socket access.
: Socket::pack_sockaddr_un(), Socket::unpack_sockaddr_un()
Added. Utility for direct Socket access.
: String#casecmp
Added. This is a case insensitive version of String#<=>.
: String#eql?
Changed to be always case sensitive.
: Module#include?
Added. [ruby-dev:13941]
: Dir::chdir
Changed to warn only when invoked from multiple threads or no block
is given. [ruby-dev:13823]
Dir.chdir("/tmp")
pwd = Dir.pwd #=> "/tmp"
puts pwd
Dir.chdir("foo") {
pwd = Dir.pwd #=> "/tmp/foo"
puts pwd
Dir.chdir("bar") { # <-- previously warned
pwd = Dir.pwd #=> "/tmp/foo/bar"
puts pwd
}
pwd = Dir.pwd #=> "/tmp/foo"
puts pwd
}
pwd = Dir.pwd #=> "/tmp"
puts pwd
: Proc#yield
Added. This is equivalent to Proc#call except it does not check the
number of given arguments, which are thus passed to the proc as-is.
: File#fnmatch, File::Constants::FNM_*
Added. Refer to the fnmatch(3) manpage for details.
e.g.
# exclude files matching "*.bak".
files.reject! { |fn| File::fnmatch?("*.bak", fn) }
: Method#==
Added.
: Multiple assignment behavior
Fixed so that "*a = nil" results in "a == []".
: 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
: NameError & NoMethodError
Moved and now NoMethodError < NameError < StandardError.
: open
Extended so that when the third argument is permission flags it
calls open(2) instead of fopen(3).
: Marshal
Fixed not to dump anonymous classes/modules.
Fixed with loading modules.
: constants
Improved at the performance of searching by using an internal hash
table.
: 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]
: 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.
