: Marshal to use marshal_dump and marshal_load
|
|
|
|
if a dumping object responds to 'marshal_dump', Marshal.dump calls
|
|
it, and dumps object returned. Marshal.load allocates a new instance
|
|
using "allocate", then calls its "marshal_load" with dumped data.

|
|

|
|
|
|
New templates 'q' and 'Q' for 64bit integer (signed and unsigned respectively).
|
|
|
|
: Array#new
|
|
|
|
Now takes block to fill initial values. E.g.
|
|

|
|
|
|
: IO#fsync
|
|
|
|
Added.
|
|
|
|
: 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
|
|
|
|
: allocation framework
|
|
|
|
any instance of class can be allocated by class.allocate,
|
|
(except a few classes).
|
|
|
|
: break and next
|
|
|
|
Extended to take an optional expression, which is used as a value
|
|
for termination. [experimental]
|
|
|
|
: 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.
|
|
|
|
: expression parenthesis in the first argument
|
|
|
|
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
|
|
|
|
: 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]
|
|
|
|
: pp module
|
|
|
|
Imported. Prity Printing library.
|
|
|
|
: open
|
|
|
|
Extended so that when the third argument is permission flags it
|
|
calls open(2) instead of fopen(3).
|
|
|
|
: Array#fetch(index [, default])
|
|
|
|
Added. If a default value isn't given, raises index error if index
|
|
is out of range.
|
|
|
|
: 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]
|
|
|
|
: Curses
|
|
|
|
Updated. New methods and constants for using the mouse, character
|
|
attributes, colors and key codes have been added.

|
|
|

|
|
|
|
Added.
|
|
|
|
: 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.
|
|
|
|
: 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
|
|
|
|
Changed to warn only when invoked from multiple threads or no block
|
|
is given. [ruby-dev:13823]
|
|
|
|
Dir.chdir('foo') {
|
|
Dir.chdir('bar') { # previously warned
|
|
puts Dir.pwd
|
|
}
|
|
}
|

|
: File#fnmatch, File::Constants::FNM_*
|
|
|
|
Added. Refer to the fnmatch(3) manpage for details.
|
|
|
|
Localism is FNM_DOTMATCH which has the opposite meaning of the
|
|
commonly known FNM_PERIOD, which does not exist in Ruby.
|
|
|
|
e.g.
|
|
|
|
# exclude files matching "*.bak" case-insensitively.
|
|
files.reject! {|fn| File.fnmatch?("*.bak", fn, File::FNM_CASEFOLD) }
|
|
|
|
: File.lchmod
|
|
: File.lchown
|
|
|
|
Added.
|
|
|
|
: File.open, IO.open
|
|
|
|
File mode can be specified by flags like open(2),
|
|
e.g. File::open(path, File::CREAT|File::WRONLY).
|
|
|
|
: IO.open
|
|
|
|
Made public. Can only associate an IO object with a file number
|
|
like IO.new and IO.for_fd, but can take a block.
|
|
|
|
: IO.for_fd
|
|
|
|
Added as a synonym for IO.new.
|
|
|
|
: IO.read
|
|
|
|
Added. Like IO.readlines, except it returns the entire file as a
|
|
string. [ruby-talk:9460]
|
|
|
|
: Interrupt
|
|
|
|
Made a subclass of SignalException. (It was a subclass of
|
|
Exception in 1.6 and prior)
|
|
|

|
|
|
Fixed not to dump anonymous classes/modules.

|
|
|
|
: Net::HTTP
|
|
|
|
New version of Net::HTTP has introduced seriously incompatible
|
|
changes. For details, see document embedded in net/http.rb itself.

|
|
|
