pd-vm Compatibility Frontends

JavaScript and Lua compatibility frontends for pd-vm.

This crate owns the compatibility-language pieces that are intentionally outside the core rustscript repository:

• JavaScript parser dialect configuration and lowering rewrites
• Lua parser/lowering helpers
• JavaScript and Lua import scanning / import stripping for source-file loading
• compatibility frontend tests and fixtures

Usage

pd-vm = "0.22.2"
pd-vm-compat-frontends = "0.1.0"

use vm::compile_source_file_with_options;

let options = pd_vm_compat_frontends::compile_options();
let compiled = compile_source_file_with_options("examples/example.js", options)?;

The crate also ships a CLI binary with the same entry surface as pd-vm-run, but with the JavaScript and Lua source plugins pre-registered:

cargo run --bin pd-vm-compat-run -- examples/example.js
cargo run --bin pd-vm-compat-run -- examples/example.lua
pd-vm-compat-run fmt --check examples/example.js
pd-vm-compat-run --emit-vmbc out.vmbc examples/example.lua

Supported extensions

• .js -> JavaScript compatibility frontend
• .lua -> Lua compatibility frontend

Core RustScript (.rss) remains in the pd-vm crate.
