Results for: "fnmatch"

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.

With a block given, calls the block with each remaining byte in the stream; see Byte IO.

With no block given, returns an enumerator.

With a block given, calls the block with each remaining codepoint in the stream; see Codepoint IO.

With no block given, returns an enumerator.

This returns the value that scan_until would return, without advancing the scan pointer. The match register is affected, though.

s = StringScanner.new("Fri Dec 12 1975 14:39")
s.check_until /12/          # -> "Fri Dec 12"
s.pos                       # -> 0
s.matched                   # -> 12

Mnemonic: it “checks” to see whether a scan_until will return a value.

Scans the string until the pattern is matched. Advances the scan pointer if advance_pointer_p, otherwise not. Returns the matched string if return_string_p is true, otherwise returns the number of bytes advanced. This method does affect the match register.

Returns the subgroups in the most recent match at the given indices. If nothing was priorly matched, it returns nil.

s = StringScanner.new("Fri Dec 12 1975 14:39")
s.scan(/(\w+) (\w+) (\d+) /)       # -> "Fri Dec 12 "
s.values_at 0, -1, 5, 2            # -> ["Fri Dec 12 ", "12", nil, "Dec"]
s.scan(/(\w+) (\w+) (\d+) /)       # -> nil
s.values_at 0, -1, 5, 2            # -> nil

Whether scanner uses fixed anchor mode or not.

If fixed anchor mode is used, \A always matches the beginning of the string. Otherwise, \A always matches the current position.

Creates GUID.

WIN32OLE.create_guid # => {1CB530F1-F6B1-404D-BCE6-1959BF91F4A8}

Calls the given block with each value; returns self:

h = {foo: 0, bar: 1, baz: 2}
h.each_value {|value| puts value } # => {:foo=>0, :bar=>1, :baz=>2}

Output:

0
1
2

Returns a new Enumerator if no block given:

h = {foo: 0, bar: 1, baz: 2}
e = h.each_value # => #<Enumerator: {:foo=>0, :bar=>1, :baz=>2}:each_value>
h1 = e.each {|value| puts value }
h1 # => {:foo=>0, :bar=>1, :baz=>2}

Output:

0
1
2

Calls the given block with each key; returns self:

h = {foo: 0, bar: 1, baz: 2}
h.each_key {|key| puts key }  # => {:foo=>0, :bar=>1, :baz=>2}

Output:

foo
bar
baz

Returns a new Enumerator if no block given:

h = {foo: 0, bar: 1, baz: 2}
e = h.each_key # => #<Enumerator: {:foo=>0, :bar=>1, :baz=>2}:each_key>
h1 = e.each {|key| puts key }
h1 # => {:foo=>0, :bar=>1, :baz=>2}

Output:

foo
bar
baz

Calls the given block with each key-value pair; returns self:

h = {foo: 0, bar: 1, baz: 2}
h.each_pair {|key, value| puts "#{key}: #{value}"} # => {:foo=>0, :bar=>1, :baz=>2}

Output:

foo: 0
bar: 1
baz: 2

Returns a new Enumerator if no block given:

h = {foo: 0, bar: 1, baz: 2}
e = h.each_pair # => #<Enumerator: {:foo=>0, :bar=>1, :baz=>2}:each_pair>
h1 = e.each {|key, value| puts "#{key}: #{value}"}
h1 # => {:foo=>0, :bar=>1, :baz=>2}

Output:

foo: 0
bar: 1
baz: 2

Returns a new Array containing values for the given keys:

h = {foo: 0, bar: 1, baz: 2}
h.values_at(:baz, :foo) # => [2, 0]

The default values are returned for any keys that are not found:

h.values_at(:hello, :foo) # => [nil, 0]
