Creating own language highlighting

[dkern]

I've created a highlighting for arduino language. But I have problems with the operators, like =, &&, ! == and so on. I don't know how to do this correctly and I found no documentation for creating new languages. I hope I did it right so far.

I've created an working example recreating my problems.

Later on, is there a way to add this language to the repository, or is this not wished?

Hi! Could you be more specific about the issue you have with the operators?

You can find documentation on language creation on this page.

Regarding the addition of this to the official repo, I'm not sure "Arduino" can be considered as a language. If I understand correctly, this is just C++.

That being said, I think it's great that you're creating your own language extension to have it highlighted as you want it to be.

Hello @Golmote

Basically you're right, it's c++ (thats why I'm extending c++ in my example), but with other function, keyswords and constants. As you see in my example. Not a decent language, but used very often. If this not suit your needs, I'm fine with it. But other tools like highlight.js supporting it already.

But back to the problem: if you take a look into my example, you see in the result on the very top, that things like = are highlighted with a background color. I don't know why this happens and how I could change this.

I made you a shorter example, where you should see the problem easily.

[Golmote]

That's because you're loading two themes at the same time. Remove prism.css ;)

Ha. Great. 👍 Typically user problem. 😉
Thanks for the hint!

So you don't want a PR/to add this to prism, correct? Then I'm hosting it by myself.

@LeaVerou Do you have an opinion on this? Should we add support for this Arduino specific C++?

[LeaVerou]

@Golmote it could inherit from C++ and just redefine the parts that are different.

[Golmote]

@LeaVerou Yes it's already what it does. I'll take that as a yes. ^^
@eisbehr- Feel free to submit a PR, then!

[dkern]

Will do! 😉
