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.

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.
See File.lstat
.
Return scanner state of current token.
Iterates over each key-value pair in the database.
If no block is given, returns an Enumerator
.
Insert or update key-value pairs.
This method will work with any object which implements an each_pair
method, such as a Hash
.
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:
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"
