Instance Method Details

#clean_markup_html ⇒ Object

Clean HTML generated by markup formatters. Such HTML tends to have extra empty lines for no apparent reason. Cleaning it up seems to be safe enough, and eliminates the ugly additional vertical space in the final HTML.

        .gsub(/\n+<\/pre>\n*/, "\n</pre>\n") \
        .sub(/^\n*/, "")
end

#to_id ⇒ Object

Convert this String to an identifier. This is a stable operation, so anything that accept a name will also accept an identifier as well.
