Instance Method Details

#filter(lexers) ⇒ Object

returns a list of lexers that match the given filename with equal specificity (i.e. number of wildcards in the pattern). This helps disambiguate between, e.g. the Nginx lexer, which matches ‘nginx.conf`, and the Conf lexer, which matches `*.conf`. In this case, nginx will win because the pattern has no wildcards, while `*.conf` has one.
