1 Introduction

bodge nanovg wrapper

Thin wrapper over NanoVG library for hardware-accelerated 2D drawing via OpenGL.

Requirements

• ASDF/Quicklisp
• x86_64/i686 GNU/Linux, macOS or Windows

Loading

(ql:quickload '(nanovg-blob bodge-nanovg))

Usage

Interface

All wrapped functions can be found in %nvg package. On the other hand, nvg package contains minimally lispified wrappers and utility functions.

Example

A bit verbose but simplest possible example can be found in example.lisp.

To run it, evaluate in your REPL:

(ql:quickload :bodge-nanovg/example)
(nanovg.example:run)

2 Systems

The main system appears first, followed by any subsystem dependency.
