#initialize(arg) ⇒ Object

Create a Pathname object from the given String (or String-like object). If path contains a NULL character (\0), an ArgumentError is raised.

Instance Method Details

#+(other) ⇒ Object Also known as: /

Appends a pathname fragment to self to produce a new Pathname object.

p1 = Pathname.new("/usr")      # Pathname:/usr
p2 = p1 + "bin/ruby"           # Pathname:/usr/bin/ruby
p3 = p1 + "/etc/passwd"        # Pathname:/etc/passwd

# / is aliased to +.
p4 = p1 / "bin/ruby"           # Pathname:/usr/bin/ruby
p5 = p1 / "/etc/passwd"        # Pathname:/etc/passwd

This method doesn't access the file system; it is pure string manipulation.

# File 'lib/pathname.rb', line 336

def +(other)
  other = Pathname.new(other) unless Pathname === other
  Pathname.new(plus(@path, other.to_s))
end

#<=>(other) ⇒ Object

Provides a case-sensitive comparison operator for pathnames.

Pathname.new('/usr') <=> Pathname.new('/usr/bin')

#=> -1

Pathname.new('/usr/bin') <=> Pathname.new('/usr/bin')

#=> 0

Pathname.new('/usr/bin') <=> Pathname.new('/USR/BIN')

#=> 1

It will return -1, 0 or 1 depending on the value of the left argument relative to the right argument. Or it will return nil if the arguments are not comparable.

#absolute?Boolean

Predicate method for testing whether a path is absolute.

It returns true if the pathname begins with a slash.

p = Pathname.new('/im/sure')
p.absolute?
    #=> true

p = Pathname.new('not/so/sure')

    #=> false

end

#ascend {|_self| ... } ⇒ Object

Iterates over and yields a new Pathname object for each element in the given path in ascending order.

Pathname.new('/path/to/some/file.rb').ascend {|v| p v}
   #<Pathname:/path/to/some/file.rb>
   #<Pathname:/path/to/some>
   #<Pathname:/path/to>

   #<Pathname:path/to/some/file.rb>
   #<Pathname:path/to/some>
   #<Pathname:path/to>
   #<Pathname:path>

It doesn't access the filesystem.

Yields:

#children(with_directory = true) ⇒ Object

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.

#cleanpath(consider_symlink = false) ⇒ Object

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.

#entriesObject

Return the entries (files and subdirectories) in the directory, each as a Pathname object.

The results contains just the names in the directory, without any trailing slashes or recursive look-up.

pp Pathname.new('/usr/local').entries
#=> [#<Pathname:share>,
#    #<Pathname:lib>,
#    #<Pathname:..>,
#    #<Pathname:include>,
#    #<Pathname:etc>,
#    #<Pathname:bin>,
#    #<Pathname:man>,
#    #<Pathname:games>,
#    #<Pathname:.>,
#    #<Pathname:sbin>,
#    #<Pathname:src>]

The result may contain the current directory #<Pathname:.> and the parent directory #<Pathname:..>.

If you don't want . and .. and want directories, consider Pathname#children.
