Hi,
I Just started working on a Emacs-inspired text editor in Rust.
Being insipred by Emacs, the most important part Is the possibiliy to implement new components.
My ideas were:
- Rust-based scripting language, like Rhai
- RustPython (slower, but more compatible and lots of people know Python)
- PyO3 (Bigger executable and not that fast)
- Wasm/Wasi (Cross-platform, but I don't know if the compatibility with Rust's hosted functions and structs is good)
- Other binded language, like V8, Lua or SpiderMonkey
- Compiled plugins, like .so or .DLL (Fast, but not compatible; there should be Rust plugin frameworks for implementing this, but I don't remember the name)
The elements to analyze are: speednees (consider it's a text editor, so...), easy-to-develop and Cross-platform (if possible, not that important), but the possibility to execute functions in the host Rust program is EXTREMELY important.
Thoughts?
Thanks in Advance.
I can recommend Lua. It is easy to learn, and easy to embed in a Rust program. With LuaJIT, it should be pretty fast, too.
Of course you can also embed a JavaScript runtime, but then your executable will probably be 50 MB larger. And I'm not a fan of Python.
Being honest, I don't really like Lua's syntax, while I love his embeddability.
A JS runtime is way too big in my opinion.
PyO3 + Python is also big, but a little big smaller beaucse the interpreter isn't embedded.
I am currenctly experimenting with both Python and WASM.
