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.
