NOTE: match?
only matches prerelease versions when dependency
is a prerelease dependency.

NOTE: matches_spec?
matches prerelease versions. See also match?
Returns true if path
matches against pattern
. The pattern is not a regular expression; instead it follows rules similar to shell filename globbing. It may contain the following metacharacters:
*
Matches any file. Can be restricted by other values in the glob. Equivalent to /.*/x
in regexp.
*
Matches all regular files
c*
Matches all files beginning with c
*c
Matches all files ending with c
*c*
Matches all files that have c
in them (including at the beginning or end).
To match hidden files (that start with a .
) set the File::FNM_DOTMATCH flag.
**
Matches directories recursively or files expansively.
?
Matches any one character. Equivalent to /.{1}/
in regexp.
[set]
Matches any one character in set
. Behaves exactly like character sets in Regexp
, including set negation ([^a-z]
).
\
Escapes the next metacharacter.
{a,b}
Matches pattern a and pattern b if File::FNM_EXTGLOB flag is enabled. Behaves like a Regexp
union ((?:a|b)
).
flags
is a bitwise OR of the FNM_XXX
constants. The same glob pattern and flags are used by Dir::glob
.
Examples:
File.fnmatch('cat', 'cat') #=> true # match entire string File.fnmatch('cat', 'category') #=> false # only match partial string File.fnmatch('c{at,ub}s', 'cats') #=> false # { } isn't supported by default File.fnmatch('c{at,ub}s', 'cats', File::FNM_EXTGLOB) #=> true # { } is supported on FNM_EXTGLOB File.fnmatch('c?t', 'cat') #=> true # '?' match only 1 character File.fnmatch('c??t', 'cat') #=> false # ditto File.fnmatch('c*', 'cats') #=> true # '*' match 0 or more characters File.fnmatch('c*t', 'c/a/b/t') #=> true # ditto File.fnmatch('ca[a-z]', 'cat') #=> true # inclusive bracket expression File.fnmatch('ca[^t]', 'cat') #=> false # exclusive bracket expression ('^' or '!') File.fnmatch('cat', 'CAT') #=> false # case sensitive File.fnmatch('cat', 'CAT', File::FNM_CASEFOLD) #=> true # case insensitive File.fnmatch('cat', 'CAT', File::FNM_SYSCASE) #=> true or false # depends on the system default File.fnmatch('?', '/', File::FNM_PATHNAME) #=> false # wildcard doesn't match '/' on FNM_PATHNAME File.fnmatch('*', '/', File::FNM_PATHNAME) #=> false # ditto File.fnmatch('[/]', '/', File::FNM_PATHNAME) #=> false # ditto File.fnmatch('\?', '?') #=> true # escaped wildcard becomes ordinary File.fnmatch('\a', 'a') #=> true # escaped ordinary remains ordinary File.fnmatch('\a', '\a', File::FNM_NOESCAPE) #=> true # FNM_NOESCAPE makes '\' ordinary File.fnmatch('[\?]', '?') #=> true # can escape inside bracket expression File.fnmatch('*', '.profile') #=> false # wildcard doesn't match leading File.fnmatch('*', '.profile', File::FNM_DOTMATCH) #=> true # period by default. File.fnmatch('.*', '.profile') #=> true File.fnmatch('**/*.rb', 'main.rb') #=> false File.fnmatch('**/*.rb', './main.rb') #=> false File.fnmatch('**/*.rb', 'lib/song.rb') #=> true File.fnmatch('**.rb', 'main.rb') #=> true File.fnmatch('**.rb', './main.rb') #=> false File.fnmatch('**.rb', 'lib/song.rb') #=> true File.fnmatch('*', 'dave/.profile') #=> true File.fnmatch('**/foo', 'a/b/c/foo', File::FNM_PATHNAME) #=> true File.fnmatch('**/foo', '/a/b/c/foo', File::FNM_PATHNAME) #=> true File.fnmatch('**/foo', 'c:/a/b/c/foo', File::FNM_PATHNAME) #=> true File.fnmatch('**/foo', 'a/.b/c/foo', File::FNM_PATHNAME) #=> false File.fnmatch('**/foo', 'a/.b/c/foo', File::FNM_PATHNAME | File::FNM_DOTMATCH) #=> true
catch
executes its block. If throw
is not called, the block executes normally, and catch
returns the value of the last expression evaluated.
catch(1) { 123 } # => 123
If throw(tag2, val)
is called, Ruby searches up its stack for a catch
block whose tag
has the same object_id
as tag2. When found, the block stops executing and returns val (or nil
if no second argument was given to throw
).
catch(1) { throw(1, 456) } # => 456 catch(1) { throw(1) } # => nil
When tag
is passed as the first argument, catch
yields it as the parameter of the block.
catch(1) {|x| x + 2 } # => 3
When no tag
is given, catch
yields a new unique object (as from Object.new
) as the block parameter. This object can then be used as the argument to throw
, and will match the correct catch
block.
catch do |obj_A| catch do |obj_B| throw(obj_B, 123) puts "This puts is not reached" end puts "This puts is displayed" 456 end # => 456 catch do |obj_A| catch do |obj_B| throw(obj_A, 123) puts "This puts is still not reached" end puts "Now this puts is also not reached" 456 end # => 123
Set
date-time format.
datetime_format
A string suitable for passing to strftime
.
Returns the date format being used. See datetime_format=
Creates an option from the given parameters params
. See Parameters for New Options.
The block, if given, is the handler for the created option. When the option is encountered during command-line parsing, the block is called with the argument given for the option, if any. See Option Handlers.
mtch.values_at(index, ...) -> array
Uses each index to access the matching values, returning an array of the corresponding matches.
m = /(.)(.)(\d+)(\d)/.match("THX1138: The Movie") m.to_a #=> ["HX1138", "H", "X", "113", "8"] m.values_at(0, 2, -2) #=> ["HX1138", "X", "113"] m.values_at(1..2, -1) #=> ["H", "X", "8"] m = /(?<a>\d+) *(?<op>[+\-*\/]) *(?<b>\d+)/.match("1 + 2") m.to_a #=> ["1 + 2", "1", "+", "2"] m.values_at(:a, :b, :op) #=> ["1", "2", "+"]
Sends a PATCH request to the path
and gets a response, as an HTTPResponse
object.
Sends a PROPPATCH request to the path
and gets a response, as an HTTPResponse
object.
Returns the element at offset index
.
With the single Integer argument index
, returns the element at offset index
:
a = [:foo, 'bar', 2] a.fetch(1) # => "bar"
If index
is negative, counts from the end of the array:
a = [:foo, 'bar', 2] a.fetch(-1) # => 2 a.fetch(-2) # => "bar"
With arguments index
and default_value
, returns the element at offset index
if index is in range, otherwise returns default_value
:
a = [:foo, 'bar', 2] a.fetch(1, nil) # => "bar"
With argument index
and a block, returns the element at offset index
if index is in range (and the block is not called); otherwise calls the block with index and returns its return value:
a = [:foo, 'bar', 2] a.fetch(1) {|index| raise 'Cannot happen' } # => "bar" a.fetch(50) {|index| "Value for #{index}" } # => "Value for 50"
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.
Reads and returns a character in raw mode.
See IO#raw
for details on the parameters.
You must require ‘io/console’ to use this method.
Scans one character and returns it. This method is multibyte character sensitive.
