I know, I'll definatly use mine
And while creating It, I learned how to do syntax highighting, which may be usefull in the future.
The reason I created it is that it will make my life easy when editing and building my OS.
Sure, I don't mean to discourage you - I also write a lot of tools that help me with debugging. For example I made a Java program that connects to the VM over the serial port and allows me to visually display task structures on the host etc. for debugging. There isn't really anything that does this. It makes sense to build that stuff, but for basic things like an IDE I rather stick to more advanced & complete solutions like Eclipse.
Hmm, didn't have success with that pair recently. Do you use one of those patches available on the Internet?
No, why patch it? IIRC I just built it for my target (--target=i686-ghost) and it works well. Maybe open a thread with your errors and I'll see if I can help.
If Emacs is a kitchen sink short of a house, Eclipse is a small country. There's a plugin for anything and everything on the Eclipse Marketplace.
I've never written a plugin to support another language but it seems quite overcomplicated and overengineered, however someone else has probably already done it.
True, Eclipse has support for literally anything software-related I've ever dealt with (even lots of proprietary stuff). I wrote a plugin to support syntax highlighting for my Capri script
language (my interpreter-fun-project) and yes - the API is a little weird - but it's not utterly terrible.
