Returns a hash of parsed elements.

Raise an ArgumentError when the string length is longer than limit. You can stop this check by passing ‘limit: nil`, but note that it may take a long time to parse.

Creates a new Date object by parsing from a string according to some typical XML Schema formats.

Date.xmlschema('2001-02-03')      #=> #<Date: 2001-02-03 ...>

Raise an ArgumentError when the string length is longer than limit. You can stop this check by passing ‘limit: nil`, but note that it may take a long time to parse.

This method is equivalent to strftime(‘%F’).

Creates a new DateTime object by parsing from a string according to some typical XML Schema formats.

DateTime.xmlschema('2001-02-03T04:05:06+07:00')
                          #=> #<DateTime: 2001-02-03T04:05:06+07:00 ...>

Raise an ArgumentError when the string length is longer than limit. You can stop this check by passing ‘limit: nil`, but note that it may take a long time to parse.

This method is equivalent to strftime(‘%FT%T%:z’). The optional argument n is the number of digits for fractional seconds.

DateTime.parse('2001-02-03T04:05:06.123456789+07:00').iso8601(9)
                          #=> "2001-02-03T04:05:06.123456789+07:00"

Parses time as a dateTime defined by the XML Schema and converts it to a Time object. The format is a restricted version of the format defined by ISO 8601.

ArgumentError is raised if time is not compliant with the format or if the Time class cannot represent the specified time.

See xmlschema for more information on this format.

require 'time'

Time.xmlschema("2011-10-05T22:26:12-04:00")
#=> 2011-10-05 22:26:12-04:00

You must require ‘time’ to use this method.

Returns a string which represents the time as a dateTime defined by XML Schema:

CCYY-MM-DDThh:mm:ssTZD
CCYY-MM-DDThh:mm:ss.sssTZD

where TZD is Z or [+-]hh:mm.

If self is a UTC time, Z is used as TZD. [+-]hh:mm is used otherwise.

fractional_digits specifies a number of digits to use for fractional seconds. Its default value is 0.

require 'time'

t = Time.now
t.iso8601  # => "2011-10-05T22:26:12-04:00"

You must require ‘time’ to use this method.

Returns a MatchData object describing the match, or nil if there was no match. This is equivalent to retrieving the value of the special variable $~ following a normal match. If the second parameter is present, it specifies the position in the string to begin the search.

/(.)(.)(.)/.match("abc")[2]   #=> "b"
/(.)(.)/.match("abc", 1)[2]   #=> "c"

If a block is given, invoke the block with MatchData if match succeed, so that you can write

/M(.*)/.match("Matz") do |m|
  puts m[0]
  puts m[1]
end

instead of

if m = /M(.*)/.match("Matz")
  puts m[0]
  puts m[1]
end

The return value is a value from block execution in this case.

Returns true or false to indicate whether the regexp is matched or not without updating $~ and other related variables. If the second parameter is present, it specifies the position in the string to begin the search.

/R.../.match?("Ruby")    #=> true
/R.../.match?("Ruby", 1) #=> false
/P.../.match?("Ruby")    #=> false
$&                       #=> nil

Returns sym.to_s.match.

Returns sym.to_s.match?.

Return true if the receiver matches the given pattern.

See File.fnmatch.

Return true if the receiver matches the given pattern.

See File.fnmatch.

Tests whether the given pattern is matched from the current scan pointer. Returns the length of the match, or nil. The scan pointer is not advanced.

s = StringScanner.new('test string')
p s.match?(/\w+/)   # -> 4
p s.match?(/\w+/)   # -> 4
p s.match?("test")  # -> 4
p s.match?(/\s+/)   # -> nil

Returns true if and only if the last match was successful.

s = StringScanner.new('test string')
s.match?(/\w+/)     # => 4
s.matched?          # => true
s.match?(/\d+/)     # => nil
s.matched?          # => false

Returns the last matched string.

s = StringScanner.new('test string')
s.match?(/\w+/)     # -> 4
s.matched           # -> "test"

Returns a new ipaddr built by masking IP address with the given prefixlen/netmask. (e.g. 8, 64, “255.255.255.0”, etc.)

Returns the netmask in string format e.g. 255.255.0.0

Set current netmask to given mask.

Puts option summary into to and returns to. Yields each line if a block is given.

to

Output destination, which must have method <<. Defaults to [].

width

Width of left side, defaults to @summary_width.

max

Maximum length allowed for left side, defaults to width - 1.

indent

Indentation, defaults to @summary_indent.

Returns the captured substring corresponding to the argument. n can be a string or symbol to reference a named capture.

m = /(.)(.)(\d+)(\d)(\w)?/.match("THX1138.")
m.match(0)       #=> "HX1138"
m.match(4)       #=> "8"
m.match(5)       #=> nil

m = /(?<foo>.)(.)(?<bar>.+)/.match("hoge")
m.match(:foo)    #=> "h"
m.match(:bar)    #=> "ge"

This is a convenience method which is same as follows:

begin
  q = PrettyPrint.new(output, maxwidth, newline, &genspace)
  ...
  q.flush
  output
end

returns main ractor

Returns the main thread.
