Results for: "match"

Calls the given block with the value of each member; returns self:

Customer = Struct.new(:name, :address, :zip)
joe = Customer.new("Joe Smith", "123 Maple, Anytown NC", 12345)
joe.each {|value| p value }

Output:

"Joe Smith"
"123 Maple, Anytown NC"
12345

Returns an Enumerator if no block is given.

Allocates space for a new object of class’s class and does not call initialize on the new instance. The returned object must be an instance of class.

klass = Class.new do
  def initialize(*args)
    @initialized = true
  end

  def initialized?
    @initialized || false
  end
end

klass.allocate.initialized? #=> false

Returns clean pathname of self with consecutive slashes and useless dots removed. The filesystem is not accessed.

If consider_symlink is true, then a more conservative algorithm is used to avoid breaking symbolic linkages. This may retain more .. entries than absolutely necessary, but without accessing the filesystem, this can’t be avoided.

See Pathname#realpath.

The opposite of Pathname#absolute?

It returns false if the pathname begins with a slash.

p = Pathname.new('/im/sure')
p.relative?
    #=> false

p = Pathname.new('not/so/sure')
p.relative?
    #=> true

Returns the children of the directory (files and subdirectories, not recursive) as an array of Pathname objects.

By default, the returned pathnames will have enough information to access the files. If you set with_directory to false, then the returned pathnames will contain the filename only.

For example:

pn = Pathname("/usr/lib/ruby/1.8")
pn.children
    # -> [ Pathname:/usr/lib/ruby/1.8/English.rb,
           Pathname:/usr/lib/ruby/1.8/Env.rb,
           Pathname:/usr/lib/ruby/1.8/abbrev.rb, ... ]
pn.children(false)
    # -> [ Pathname:English.rb, Pathname:Env.rb, Pathname:abbrev.rb, ... ]

Note that the results never contain the entries . and .. in the directory because they are not children.

Creates a full path, including any intermediate directories that don’t yet exist.

See FileUtils.mkpath and FileUtils.mkdir_p

Returns the real (absolute) pathname for self in the actual filesystem.

Does not contain symlinks or useless dots, .. and ..

All components of the pathname must exist when this method is called.

Returns the real (absolute) pathname of self in the actual filesystem.

Does not contain symlinks or useless dots, .. and ..

The last component of the real pathname can be nonexistent.

Returns the last access time for the file.

See File.atime.

Changes file permissions.

See File.chmod.

Same as Pathname.chmod, but does not follow symbolic links.

See File.lchmod.

Change owner and group of the file.

See File.chown.

Same as Pathname.chown, but does not follow symbolic links.

See File.lchown.

Returns a File::Stat object.

See File.stat.

See File.lstat.

Truncates the file to length bytes.

See File.truncate.

See FileTest.chardev?.

Return scanner state of current token.

creates a new socket object connected to host:port using TCP/IP.

If local_host:local_port is given, the socket is bound to it.

The optional last argument opts is options represented by a hash. opts may have following options:

:connect_timeout

specify the timeout in seconds.

If a block is given, the block is called with the socket. The value of the block is returned. The socket is closed when this method returns.

If no block is given, the socket is returned.

Socket.tcp("www.ruby-lang.org", 80) {|sock|
  sock.print "GET / HTTP/1.0\r\nHost: www.ruby-lang.org\r\n\r\n"
  sock.close_write
  puts sock.read
}

iterates over the list of Addrinfo objects obtained by Addrinfo.getaddrinfo.

Addrinfo.foreach(nil, 80) {|x| p x }
#=> #<Addrinfo: 127.0.0.1:80 TCP (:80)>
#   #<Addrinfo: 127.0.0.1:80 UDP (:80)>
#   #<Addrinfo: [::1]:80 TCP (:80)>
#   #<Addrinfo: [::1]:80 UDP (:80)>

returns an addrinfo object for TCP address.

Addrinfo.tcp("localhost", "smtp") #=> #<Addrinfo: 127.0.0.1:25 TCP (localhost:smtp)>

Returns the path of the local address of unixsocket.

s = UNIXServer.new("/tmp/sock")
p s.path #=> "/tmp/sock"

Calls the block with each remaining line read from the stream; does nothing if already at end-of-file; returns self. See Line IO.

StringIO#each is an alias for StringIO#each_line.
