lovm2

lovm2 is a library for building your own programming language in the blink of an eye. It offers you easy to use constructs to generate bytecode for its virtual machine.

Features

• Dynamic typing
• Generate bytecode using a High-Level Intermediate Representation
• Define own instructions as Interrupts
• Extend your programs with Rust: lovm2 extend
• Standard library included: lovm2_std
• Python bindings: pylovm2

Examples

Add this line to your Cargo.toml:

toml lovm2 = "0.4.8"

Projects

• lol - a lisp language
• quasicode - the best language around

Generating Bytecode

``` rust use lovm2::prelude::*;

let mut module = ModuleBuilder::new();

// a module needs a code object called main // if you want to make it runnable let main_hir = module.entry();

// set the local variable n to 10 mainhir.step(Assign::local(&lv2var!(n), 10));

// print is a builtin function. the lv2_var! macro // ensures that the given identifier is not confused // with a string. mainhir.step(Call::new("print").arg(lv2var!(n)).arg("Hello World")); // ... this is equivalent to the developer-friendly version: mainhir.step(lv2call!(print, n, "Hello World"));

// creates a Module from the ModuleBuilder let module = module.build().unwrap(); println!("{}", module);

// load the module and run it let mut vm = createvmwithstd(); vm.addmain_module(module).expect("load error"); vm.run().expect("run error"); ```
