Hello @benedfit

Thank you for your GREAT TOOL!!

I encontered this error (below) when I ran jade-lint in my project. I called jade-lint from gulp.

node_modules/jade-lint/lib/rules/validate-attribute-quote-marks.js:26
            , openingQuote = value.charAt(0)
                                   ^
TypeError: Object true has no method 'charAt'

Hey @eiichiro-takahashi, thanks for the PR, unfortunately the tests are currently failing as a result. I'm happy to fix, but need a little more details on the Jade in question that you we're getting this error for

Cheers

@eiichiro-takahashi I worked out that boolean attributes were the issue here and have released a fix in v1.0.2. Hope it helps
