Interesting, this is basically a very simple interpreter with a REPL. You should look into interpreters if this is something you enjoyed creating, there are many efficient and simple algorithms you could use to make this program a lot simpler and even more advanced too. For instance, recursive descent parsing, and the shunting yard algorithm.
I always found DropBox a pain, you have to email them the link, which is a bit more effort than saying going to a short URL and typing in a password. So I could see this being somewhat useful :)
Only thing I could think of is that you can transfer it from one computer to another quickly. And you don't need to create an account (like say if I transferred it through DropBox), just type in a password.
I'm most proud of my compiler for my programming language, it's still in the works, but the fact that it does somewhat work and I made it from scratch makes me happy :)
Ah, that's a Mac font. I'm on Linux, but you should try a more general monospaced font like Consolas, or there's probably one on Google Fonts you can use.
May as well add to this, but we're actually looking for contributors to help out, so if you're interested in working on a fairly new language then send us a PR :)
Hi. I'm the guy that made this :) We're just having fun, we don't see this to replace any existing language like Rust, C or Go. It's still a really small project.
Interesting idea, you should clean it up into multiple files and put it on an actual repository. If you compiled all of Java's libraries, would you be able to self host the trans-compiler?
