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.
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 the size of the most recent match in bytes, or nil if there was no recent match. This is different than matched.size, which will return the size in characters.
s = StringScanner.new('test string') s.check /\w+/ # -> "test" s.matched_size # -> 4 s.check /\d+/ # -> nil s.matched_size # -> nil
Create a new MatchPredicateNode node
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.
Create a new MatchLastLineNode node
Create a new MatchRequiredNode node
Create a new MatchWriteNode node
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`.
