Indicates no such domain was found.
Domain Name resource abstract class.
Raised when the tree is malformed or there is a bug in the compiler.
Returns true or false based on whether a match is found for self and pattern.
Note: does not update Global Variables at Regexp.
Computes regexp by converting pattern (if not already a Regexp).
regexp = Regexp.new(pattern)
Returns true if self+.match(regexp) returns a MatchData object, false otherwise:
'foo'.match?(/o/) # => true 'foo'.match?('o') # => true 'foo'.match?(/x/) # => false
If Integer argument offset is given, the search begins at index offset:
'foo'.match?('f', 1) # => false 'foo'.match?('o', 1) # => true
Return the matchee associated with this NoMatchingPatternKeyError exception.
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
Equivalent to sym.to_s.match?; see String#match.
Attempts to [match] the given pattern at the beginning of the [target substring]; does not modify the [positions].
If the match succeeds:
Sets [match values].
Returns the size in bytes of the matched substring.
scanner = StringScanner.new('foobarbaz') scanner.pos = 3 scanner.match?(/bar/) => 3 put_match_values(scanner) # Basic match values: # matched?: true # matched_size: 3 # pre_match: "foo" # matched : "bar" # post_match: "baz" # Captured match values: # size: 1 # captures: [] # named_captures: {} # values_at: ["bar", nil] # []: # [0]: "bar" # [1]: nil put_situation(scanner) # Situation: # pos: 3 # charpos: 3 # rest: "barbaz" # rest_size: 6
If the match fails:
Clears match values.
Returns nil.
Does not increment positions.
scanner.match?(/nope/) # => nil match_values_cleared?(scanner) # => true
Returns true of the most recent [match attempt] was successful, false otherwise; see [Basic Matched Values]:
scanner = StringScanner.new('foobarbaz') scanner.matched? # => false scanner.pos = 3 scanner.exist?(/baz/) # => 6 scanner.matched? # => true scanner.exist?(/nope/) # => nil scanner.matched? # => false
Returns the matched substring from the most recent [match] attempt if it was successful, or nil otherwise; see [Basic Matched Values]:
scanner = StringScanner.new('foobarbaz') scanner.matched # => nil scanner.pos = 3 scanner.match?(/bar/) # => 3 scanner.matched # => "bar" scanner.match?(/nope/) # => nil scanner.matched # => nil
Returns the size (in bytes) of the matched substring from the most recent match [match attempt] if it was successful, or nil otherwise; see [Basic Matched Values]:
scanner = StringScanner.new('foobarbaz') scanner.matched_size # => nil pos = 3 scanner.exist?(/baz/) # => 9 scanner.matched_size # => 3 scanner.exist?(/nope/) # => nil scanner.matched_size # => nil
Does this dependency match the specification described by name and version or match spec?
NOTE: Unlike matches_spec? this method does not return true when the version is a prerelease version unless this is a prerelease dependency.
Does this dependency match spec?
NOTE: This is not a convenience method. Unlike match? this method returns true when spec is a prerelease version even if this dependency is not a prerelease dependency.
Return all files in this gem that match for glob.
@return true if the specs of any default gems are ‘==` to the given `spec`.
