Many tools written in node.js just use a JSON file (or a JSON-like file, like yaml or hjson) for configuration. That works well for some stuff (except JSON; that’s generally a pain to write and has no comments), but they’re all sorely missing a way to spread your configuration out across multiple files.
HConfig my project to remedy that problem for my own projects; a dependency free parser for a new, JSON-like configuration format which makes it possible to include other files. I figured I’d put it on github and share it with the world. I’m also interested in constructive feedback.
