Results for: "fnmatch"

Returns the path associated with the IO, or nil if there is no path associated with the IO. It is not guaranteed that the path exists on the filesystem.

$stdin.path # => "<STDIN>"

File.open("testfile") {|f| f.path} # => "testfile"

See as_json.

Yields all attributes (as symbols) along with the corresponding values or returns an enumerator if no block is given.

require "ostruct"
data = OpenStruct.new("country" => "Australia", :capital => "Canberra")
data.each_pair.to_a   # => [[:country, "Australia"], [:capital, "Canberra"]]

See as_json.

With a block given, passes each element of self to the block in reverse order:

a = []
(1..4).reverse_each {|element| a.push(element) } # => 1..4
a # => [4, 3, 2, 1]

a = []
(1...4).reverse_each {|element| a.push(element) } # => 1...4
a # => [3, 2, 1]

With no block given, returns an enumerator.

See as_json.

See as_json.

See as_json.

Calls the given block with each member name/value pair; returns self:

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

Output:

"name => Joe Smith"
"address => 123 Maple, Anytown NC"
"zip => 12345"

Returns an Enumerator if no block is given.

Related: each.

Returns an array of values from self.

With integer arguments integers given, returns an array containing each value given by one of integers:

Customer = Struct.new(:name, :address, :zip)
joe = Customer.new("Joe Smith", "123 Maple, Anytown NC", 12345)
joe.values_at(0, 2)    # => ["Joe Smith", 12345]
joe.values_at(2, 0)    # => [12345, "Joe Smith"]
joe.values_at(2, 1, 0) # => [12345, "123 Maple, Anytown NC", "Joe Smith"]
joe.values_at(0, -3)   # => ["Joe Smith", "Joe Smith"]

Raises IndexError if any of integers is out of range; see Array Indexes at Array.

With integer range argument integer_range given, returns an array containing each value given by the elements of the range; fills with nil values for range elements larger than the structure:

joe.values_at(0..2)
# => ["Joe Smith", "123 Maple, Anytown NC", 12345]
joe.values_at(-3..-1)
# => ["Joe Smith", "123 Maple, Anytown NC", 12345]
joe.values_at(1..4) # => ["123 Maple, Anytown NC", 12345, nil, nil]

Raises RangeError if any element of the range is negative and out of range; see Array Indexes at Array.

See as_json.

Returns true if this class can be used to create an instance from a serialised JSON string. The class has to implement a class method json_create that expects a hash as first parameter. The hash should include the required data.

Iterates over each component of the path.

Pathname.new("/usr/bin/ruby").each_filename {|filename| ... }
  # yields "usr", "bin", and "ruby".

Returns an Enumerator if no block was given.

enum = Pathname.new("/usr/bin/ruby").each_filename
  # ... do stuff ...
enum.each { |e| ... }
  # yields "usr", "bin", and "ruby".

Return the path as a String.

to_path is implemented so Pathname objects are usable with File.open, etc.

Iterates over each line in the file and yields a String object for each.

Creates a hard link at pathname.

See File.link.

Creates a symbolic link.

See File.symlink.

Returns the absolute path for the file.

See File.expand_path.

Iterates over the entries (files and subdirectories) in the directory, yielding a Pathname object for each entry.

Returns true for IPv4 private address (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16). It returns false otherwise.

Returns true for IPv4-mapped IPv6 address (::ffff:0:0/80). It returns false otherwise.

Returns true for IPv4-compatible IPv6 address (::/80). It returns false otherwise.

Returns the socket path as a string.

Addrinfo.unix("/tmp/sock").unix_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.
