Results for: "to_proc"

Returns a string in an ISO 8601 format. (This method doesn’t use the expanded representations.)

DateTime.new(2001,2,3,4,5,6,'-7').to_s
                         #=> "2001-02-03T04:05:06-07:00"

Returns the value of time as an integer number of seconds since the Epoch.

t = Time.now
"%10.5f" % t.to_f   #=> "1270968656.89607"
t.to_i              #=> 1270968656

Returns the value of time as a floating point number of seconds since the Epoch.

t = Time.now
"%10.5f" % t.to_f   #=> "1270968744.77658"
t.to_i              #=> 1270968744

Note that IEEE 754 double is not accurate enough to represent the number of nanoseconds since the Epoch.

Returns the value of time as a rational number of seconds since the Epoch.

t = Time.now
p t.to_r            #=> (1270968792716287611/1000000000)

This methods is intended to be used to get an accurate value representing the nanoseconds since the Epoch. You can use this method to convert time to another Epoch.

Returns a string representing time. Equivalent to calling strftime with the appropriate format string.

t = Time.now
t.to_s                              => "2012-11-10 18:16:12 +0100"
t.strftime "%Y-%m-%d %H:%M:%S %z"   => "2012-11-10 18:16:12 +0100"

t.utc.to_s                          => "2012-11-10 17:16:12 UTC"
t.strftime "%Y-%m-%d %H:%M:%S UTC"  => "2012-11-10 17:16:12 UTC"

Returns a ten-element array of values for time:

[sec, min, hour, day, month, year, wday, yday, isdst, zone]

See the individual methods for an explanation of the valid ranges of each value. The ten elements can be passed directly to Time::utc or Time::local to create a new Time object.

t = Time.now     #=> 2007-11-19 08:36:01 -0600
now = t.to_a     #=> [1, 36, 8, 19, 11, 2007, 1, 323, false, "CST"]

Converts the contents of the database to an array of [key, value] arrays, and returns it.

Returns the values for this struct as an Array.

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

Returns a Hash containing the names and values for the struct’s members.

Customer = Struct.new(:name, :address, :zip)
joe = Customer.new("Joe Smith", "123 Maple, Anytown NC", 12345)
joe.to_h[:address]   #=> "123 Maple, Anytown NC"

Returns a description of this struct as a string.

Returns an integer representing the numeric file descriptor for ios.

$stdin.fileno    #=> 0
$stdout.fileno   #=> 1

Returns an array of all key-value pairs contained in the database.

Converts the OpenStruct to a hash with keys representing each attribute (as symbols) and their corresponding values.

require "ostruct"
data = OpenStruct.new("country" => "Australia", :capital => "Canberra")
data.to_h   # => {:country => "Australia", :capital => "Canberra" }

Convert this range object to a printable form (using to_s to convert the begin and end objects).

Returns a string containing the regular expression and its options (using the (?opts:source) notation. This string can be fed back in to Regexp::new to a regular expression with the same semantics as the original. (However, Regexp#== may not return true when comparing the two, as the source of the regular expression itself may differ, as the example shows). Regexp#inspect produces a generally more readable version of rxp.

r1 = /ab+c/ix           #=> /ab+c/ix
s1 = r1.to_s            #=> "(?ix-m:ab+c)"
r2 = Regexp.new(s1)     #=> /(?ix-m:ab+c)/
r1 == r2                #=> false
r1.source               #=> "ab+c"
r2.source               #=> "(?ix-m:ab+c)"

Returns the name or string corresponding to sym.

:fred.id2name   #=> "fred"
:ginger.to_s    #=> "ginger"

Return the path as a String.

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

Returns a new Array containing each key-value pair in the database.

Example:

require 'sdbm'

SDBM.open 'my_database' do |db|
  db.update('apple' => 'fruit', 'spinach' => 'vegetable')

  db.to_a  #=> [["apple", "fruit"], ["spinach", "vegetable"]]
end

returns the socket address as packed struct sockaddr string.

Addrinfo.tcp("localhost", 80).to_sockaddr
#=> "\x02\x00\x00P\x7F\x00\x00\x01\x00\x00\x00\x00\x00\x00\x00\x00"

Returns self. If called on a subclass of Hash, converts the receiver to a Hash object.

Converts hsh to a nested array of [ key, value ] arrays.

h = { "c" => 300, "a" => 100, "d" => 400, "c" => 300  }
h.to_a   #=> [["c", 300], ["a", 100], ["d", 400]]

Return the contents of this hash as a string.

h = { "c" => 300, "a" => 100, "d" => 400, "c" => 300  }
h.to_s   #=> "{\"c\"=>300, \"a\"=>100, \"d\"=>400}"

Converts the environment variables into an array of names and value arrays.

ENV.to_a # => [["TERM", "xterm-color"], ["SHELL", "/bin/bash"], ...]

Returns “ENV”
