Hi @macbre!

What about having a metric giving the average length of selectors?

For example:

div .foo {}
div .bar {}
div .foo .bar {}

has an average complexity of 2.333

By the way, is there a reason why analyze-css doesn't count attribute expressions in the complexity? For example .form_b2_legacy .row-fluid input[class*="span"] has 4 expressions but is not in the complexSelectors offenders.

Report duplicated CSS properties.

.foo {
  background:#474646;
  border:1px solid #6b6a6a;
  background:#4c4b4b;
  border:1px solid #6b6a6a;
  margin-bottom:10px;
}

After doing sudo npm install --global analyze-css

I get the following output in my log :

Hi!

I've seen that the CSS parser used by analyze-css has a 'silent' option: https://github.com/reworkcss/css#cssparsecode-options

Here's my idea: analyze-css could parse the CSS file a first time without this option, to detect any parsing error. Then, if there is one, restart parsing in silent mode so the rest of the file can be analyzed despite the error.

Hey there, I noticed that selectors like "body > .foo .bar" return to be a redundantBodySelector, even though the body selector is combined with a child selector. Is this wanted behaviour? Thanks, Matt

Hello,

For exemple on this stylesheet: http://www.laredoute.fr/css/1/fr-FR/bundles/master?v=5f2VA4kNn1isin_Q20pvCYNBAA2CHJajWpBg8zy4l4Q1

There is @font-face (8 times) in the duplicated selectors offenders. It might be a little bug!

Hi @macbre,

The redundant body selector could be extended to some other rules. li elements are always inside ul elements, but i often see this kind of rules in stylesheets: .content ul li

Same thing for select option, table tr, tr td and probably some other cases i'm forgetting.

I just wanted to let you know that I've made an analyze-css grunt task.

https://www.npmjs.org/package/grunt-contrib-analyze-css

npm i grunt-contrib-analyze-css

It uses configurable threshold and compare the analyze-css result with to it.

Hi — love analyze-css and really want to be able to use it with phantomas. :)

I struck a hurdle though as the server I want to run tests against has in invalid self-signed SSL cert.

Currently analyze-css will explode with Error: HTTP request failed: Error: SELF_SIGNED_CERT_IN_CHAIN trying to fetch content from this server.

This PR adds an --ignore-ssl-errors bool flag that will allow for getting content from servers that have busted SSL certs. It makes a few changes to option passing in the main executable, and changes the request method in the runner to take an object instead of just a URL as a string.

Phantomas integration

I would love to add a follow-on PR for phantomas that will pass down along the --ignore-ssl-errors option from phantomas into analyze-css, however I’m not sure if this is the right thing to do (seems to make most sense?), and also not sure how you want to handle the version locking between the two (assuming this PR is accepted and a release made).

Cheers! :)
