Reverse level

[felixsanz]

Doesn't level works as opposite as its supposed to?

For example, i want to give an id attribute to my main headers, h1, h2 and h3, but i can't use the level attribute to control that. How i'm supposed to exclude the h4 ones? It should work the opposite :/

level: 3 <- minimum header level of 3 to apply the functionality.

But right now that's just adding the attributes to h3-h6 tags, which is... weird.

Makes sense. Initially my thought was mostly to exclude h1 because the page I was working on had only one h1 and I didn't want give it an anchor, that's why it works this way.

But it think it would be a good idea to make level more flexible, supporting something like level: [1, 3] in your case.

I'll give it a shot over the week-end.

Thats great, an array with the levels where you want to have ids/anchors.

My issue is because i have headings like:

<h4><code>options</code></h4>
<ul>
<li>active: true</li>
<li>...</li>
</ul>

And because my heading doesn't contain text, it's generated like <h4 id=""><code>...</code></h4>, which is invalid. So i want to disable this functionality in <h4> headings, where i usually put code tags.

Oh, interesting, I'd also consider this as a bug, the ID should be a slugified version of the code too. I'm looking into this.

Hmm, I just tested the following:

equal(
  md({ html: true }).use(anchor).render('#### <code>options</code>'),
  '<h4 id="options"><code>options</code></h4>\n'
)

And it actually passes. What versions of markdown-it and markdown-it-anchor are you using?

Edit: ha, the following indeed have empty ID, I need to fix this.

equal(
  md().use(anchor).render('#### `options`'),
  '<h4 id="options"><code>options</code></h4>\n'
)

[valeriangalliat]

I fixed both issues; the inline code is now also used to generate the ID, and you can pass an array of header levels to select in the level option.

It's published as of 4.0.0.

Note that I also dropped Babel support in 4.0.0 so this module only works with a Node version with ES6 support.

Works great, thanks!
