I am having trouble loading my language. I believe my language plugin is in error. about lang-example

I was hoping to ask for help? I can't find a discord or an irc channel, and I'm not sure what to do next.

There's a forum for this kind of thing.

Language tests tend to test for parse structure. In-editor highlighting also requires highlight tags to be set up correctly. Do the names in your styleTags call match the node names in the syntax tree? Are you actually using any of those styled nodes in your test editor?

They do.

Are you actually using any of those styled nodes in your test editor?

Yes.

In case someone else finds this, the problem was simple. CodeMirror only highlights the topmost, exposed rule.

Unfortunately, my language needs a superior rule to disambiguate between barewords and keywords, which in my highlighter is called "Chain," so I don't know how to highlight the things it's made from. If I assign a color to Chain it works as expected. The problem was that I was trying to highlight String, Atom, Arrow, and so on, and the editor isn't distinguishing those.

As far as I can tell, the things beneath the top level production aren't actually exposed, even if they're capitalized. I don't really understand how that can be the case; I would have expected it to highlight all the way down through the rule to its subordinate pieces, so that an expr could have strings and numbers inside, or what have you.

Maybe the /... notation in styleTags is what you're looking for?

Hm. It seems like it ought to be, but also, I'm not able to make that work out.

I did as you asked, and made a forum thread (although I see you responded there as well.) I'll consolidate there.
