A survey about programming language support for LiveSplit One's Auto Splitting Runtime

Auto Splitting Runtime Support

Supported languages

Rust

  • πŸ‘ Modern language with really good WebAssembly support
  • πŸ‘ Great ecosystem where most crates work perfectly fine in WebAssembly
  • πŸ‘ Easy project setup
  • πŸ‘Ž Ownership and borrowing make things a little harder
  • πŸ‘Ž WebAssembly files are not small by default (you need a bunch of flags, no_std and co.)

C

  • πŸ‘ Good WebAssembly support
  • πŸ‘ What you see is what you get (full control over memory)
  • πŸ‘Ž Not super trivial to set up a project (need WASI or other WASM sysroot and makefiles / CMake)
  • πŸ‘Ž No modern language features

TinyGo

  • πŸ‘ Easy language
  • πŸ‘ Small WebAssembly files by default
  • πŸ‘Ž Requires WASI (only a single import for writing an abort message though, could easily be snipped)
  • πŸ‘Ž Project setup is absurd (GOROOT, GOPATH, go.mod, ...)
  • πŸ‘Ž Huge compiler toolchain (2 GiB)

AssemblyScript

  • πŸ‘ Easy language (TypeScript, though with a few semantic differences)
  • πŸ‘ Very small WebAssembly files by default
  • πŸ‘ Easy project setup
  • πŸ‘Ž Limited and unclear limitations compared to real TypeScript
  • πŸ‘Ž Toxic maintainers (project may even be half abandoned)

Interpreted languages (WIP support)

TypeScript / JavaScript

  • πŸ‘ Easy language
  • πŸ‘ Easy project setup
  • πŸ‘Ž Slow due to being interpreted
  • πŸ‘Ž The default number type is unsuitable for addresses (floating point)

Not yet supported languages

Go

Early WASI support with no custom imports or exports yet.

C#

Early WASI support with no custom imports or exports yet.

Dart

Requires unfinished WASM proposals such as WASM GC that our runtime doesn't support yet. Freestanding support is somewhat unclear.
