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.
