Dust is part of a bigger project consisting of a blog with coding tutorials and various projects. Check the Website.
Dust ist a node.js driven versatile command line suite for new and experienced C64 programmers on Mac OSX. This first version installs and configures the tool chain and helps you to kickstart cross-development projects.
Install node.js from nodejs.org for your operating system. Then install dust via the node package manager
sudo npm install -g dustlayer
Then you are good to go, typical you want to setup the tools:
dust setup [... once this is done ...] dust test # shows if everything is in place
Download a tutorial to check if your setup works:
cd ~ dust tutorials # list tutorial code and select one for download # cd into the directory and run dust compile dust compile # compiles the C64 code and runs it in the C64 Emulator
or open the project in Sublime first and build from context menu
# cd into the directory sublime .
Then hit CMD-B - if nothing happens, you need to select one time the appropriate build system in Tools->Build System->C64-6502, then hit again CMD-B
