Anything that’s ever inside a tag with some attribute (eg. no-perchance) would not be evaluated whatsoever. This could be an easy way to allow creators to skip evaluation for entire sections of their page when they know they never want stuff in there evaluated. Also saves processing time looping through those elements (presumably), etc.

Or potentially, even provide a $ignoreHtmlSelector property (defaulting to [no-perchance] perhaps) to let the creator straight-up tell the engine what to ignore.

You could use the .closest(selector) on a node to figure out if it’s in an ignored element. Or perhaps do a document.querySelectorAll(":not(" + $ignoreHtmlSelector + ")") to find only the elements you need to evaluate within and loop over those.

    Agreed, something like that would be handy. Something you can do in the meantime, which isn’t ideal, but may be useful is use a script tag with a type set to something other than text/javascript and module, and then replace its outerHTML with its innerHTML:

    <script id="foo" type="text/plain">
    [foo]{1|2|3}<b>hi</b>
    </script>
    <script>foo.outerHTML = foo.innerHTML;</script>

    And here’s an example where we put markdown in the script:

    <script id="markdownScript" type="text/plain">
    # Hello
    This is *markdown*. [Notice that](https://perchance.org/welcome) Perchance syntax is ignored in here. {1|2|3}
    
    * That's because the perchance engine doesn't parse the text that's inside scripts.
    * You just need to set the 'type' attribute to something like text/plain or text/markdown to indicate to the browser that it shouldn't be executed as javascript.
    </script>
    
    <script src="https://cdn.jsdelivr.net/npm/[email protected]/marked.min.js"></script>
    <script>markdownScript.outerHTML = marked.parse(markdownScript.textContent)</script>

    @[email protected] @[email protected] I figure y’all might be interested in this technique. When I get around to cleaning up all the plugin pages, adding dark mode, etc. I’ll probably do something like this. Mostly better than defining plugin explanations in the lists panel, since that bloats the importer’s generator with that unused content. The downside is that you can’t use any Perchance syntax inside the script, so you may need to use multiple scripts with gaps in between, and use Perchance syntax within those gaps.

    Better to use this than the jsdelivr script tag though: https://perchance.org/markedjs-plugin since that way it doesn’t require an extra request during page load, which your whole page would have to wait for. Example using the plugin: https://perchance.org/zf36rys0c6#edit (same as above code block, but with marked = {import:markedjs-plugin} in the lists panel instead of the <script>)

      Ah, good idea! So it seems you essentially have some sort of “skip script tags” in place already. Hopefully it’s just a case of expanding that, when the time comes.

      Honestly, it’s still very mind-bendy trying to guess at what will and won’t be evaluated, and when I need to pre-evaluate or pre-escape or not do anything at all. The fact things work differently if done with a code block vs script also complicates things in my brain.

      I pride myself on how fast I’m able to learn and internalise systems. But this aspect of perchance has been a real challenge 😅
