About G-Code Syntax
VSCode G-Code Syntax is the premier extension for editing G-Code inside of VSCode. Going past the simple syntax highlighting, this extension aims to turn your editor into a full blown g-code management suite. Building on the features of VSCode like Intellisense, snippets, debugging and more, we are able to offer nearly all of the features you would see in very expensive proprietary editors.
Additionally, by editing your G-Code inside of VSCode, you can take advantage of source control using Git to manage your g-code file versions.

VSCode or Visual Studio Code is a FREE (as in beer), open source application for editing code of all kinds of programming languages. To make it even better, there is a great marketplace where you can download and add extensions to the application to support other languages, add features and more.
