Nftables

A Sublime Text 3+ syntax definition for your nftables rules

Introduction

nftables should now be the regular way of handling Netfilter rules, and I was surprised not to find any syntax definition for Sublime Text.
This project aims to provide a "basic" one, as long as a building procedure for GNU/Linux users (when the nft binary is available for "dynamic" syntax checks).

This project has been inspired by the official nano syntax definition.
See the Scripting nftables Wiki page for external reference.

Frequently Asked Questions

Do you plan to support the whole nftables syntax ?

No, but feel free to contribute.

Why does this syntax coloration s*cks ?

Well, sorry to hear that. Grammar wasn't my favorite course at school.
I'd be pleased to review any issue or pull request.

Why didn't you convert the official Bison parser to Sublime's definition syntax ?

It looks like such a tool does not exist (yet ?).

Would this plugin help me building a secure fire-wall ?

No, but I would advise you this blog post as a well-explained starting point, written by @tasn.

I've noticed you got an extensive tests suite, can I run it ?

Of course, open the Nftables.sublime-syntax file, press CTRL + Shift + B and choose Build With: Syntax Tests.
