Investigate using a local copy of HTML CodeSniffer

[whymarrh]

I am interested in this. What would this involve?

From the looks of it, the HTMLCS.js script that is being injected into the document (lines 107 - 109 in lib/pa11y.js) seems to be self-contained. Would it be possible/a good idea for a URL/local file to be passed as an option and then have the contents of the script read from that?

To be honest I haven't properly investigated yet. I know some CSS files are loaded in the bookmarklet, but I don't think they're integral to pa11y. Thanks for taking a look! If this is important to you, either I can prioritise or (even better) you could have a go at adding it :)

Thanks for the response!

I'll try my hand at adding it and see how it goes.

I added a command line option that allows you give a local URL for the HTML_CodeSniffer JavaScript (which, after a more detailed look is not self-contained - it, depending on what standard is given, loads a ruleset JS file).

Use case:

To use pa11y offline, I can clone the HTML_CodeSniffer repo to my local disk and run a server in the root directory. I can then specify localhost as the source for the JS.

I wasn't sure what letter to give to the option, so it's currently -c and --htmlcs. I can add some documentation to the README if those names are okay.

Let me know what you think.
