def Ripper.tokenize(src, filename = '-', lineno = 1, **kw)
Lexer.new(src, filename, lineno).tokenize(**kw)
end
Tokenizes the Ruby program and returns an array of strings. The filename and lineno arguments are mostly ignored, since the return value is just the tokenized input. By default, this method does not handle syntax errors in src, use the raise_errors keyword to raise a SyntaxError for an error in src.
Example
p Ripper.tokenize("def m(a) nil end") # => ["def", " ", "m", "(", "a", ")", " ", "nil", " ", "end"]
