navm 0.9.0-beta.1

NaVM

A VM designed to be fast, intended for use in scripting languages.

It's sometimes written navm instead of NaVM, both are the same

Getting Started

These instructions will get you a copy of NaVM with its very basic instuctions, which will serve as a demo. Remember, NaVM is not built to be a standalone application, it's meant to be used as a library (originally built for QScript, but everyone's free to use it).

See source/app.d to see how to add new instructions, & execute byte codes.

See spec/syntax.md and spec/instructions.md for NaVM's syntax and a list of instructions you can use.

See examples/* for some example byte codes. These can be run using the demo build.

Prerequisites

You need to have these present on your machine:

1. dub
2. dlang compiler (dmd works)

Building

Run:

dub fetch navm

to download this package, and then run:

dub build navm -b=release -c=demo

to fetch dependencies and build NaVM. Following this, you will have the NaVM binary (named demo) with very basic functionality.

You can now run NaVM bytecode using:

~/.dub/packages/navm-*/navm/demo path/to/bytecodefile

The demo program contains 4 additional instructions:

• writeInt - pops 1 integer from stack, and writes it to stdio.
• writeDouble - pops 1 double from stack, and writes it to stdio.
• writeChar - pops 1 char from stack, and writes it to stdio.
• writeStr - pops 1 string (array of char) from stack, and writes it to stdio.
