Help needed with HTMLCompletionProvider and HtmlTypedTextInterceptor

[Chris2011]

I'm working on a feature to automatically close html tags as you can see it here in

VS Code:

or in WebStorm:

So right after I hit ">" I want to insert the closing tag of the corresponding open tag e.g. <div"></div>" In general, it was easy, I found the part in the HtmlTypedTextInterceptor. So I added a function, check for opening tag and automatically add the end tag. So far so good. This works for those examples:

<div> -> <div>|</div>
<div class=""> -> <div class="">|</div>

There is, atm just one problem where the inteceptor, not intercept: <div class="t"> -> <div class="t"> (Code completion comes up)

So my problem is that the difference between <div class=""> and <div class="t"> is the value inside the quotes of the class attribute. I jumped in with the debugger and I can't figure out why the Interceptor doesn't jump in here. With the value, the HtmlCompletionProvider jumps in.

Can someone please give me a hint where to find when the HtmlCompletionProvier jumps in and when HtmlTypedTextInterceptor? I need to check what's going on with the value and trying to fix this.

You are hitting a border case. There are two different mime types at play here:

• text/html (outside)
• text/css (the "t" token behind class)

You can observe this, if you put a breakpoint in org.netbeans.modules.editor.lib2.typinghooks.TypedTextInterceptorsManager#getInterceptors (current master line 170 for example). Then type the ``>after"t"`. You observe, that the reported `mimePath` is ` text/html/text/css`.
