: Digest module
|
||
|
||
Added as a replacement for md5 and sha1 modules.
|
||
|
||
require 'digest/md5'
|
||
include Digest
|
||
|
||
md = MD5.new
|
||
md << "abc"
|
||
puts md
|
||
|
||
puts MD5.hexdigest("123")
|
||
|
||
: 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]
|
||
|
||
: 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.
|
||
