vim-nftables

VIM Syntax for NFTABLES.

BETA, it is in BETA stage

Currently at v0.9.0. Pretty solid but finer aspect of syntax enforcement is not fully implemented hence has been disabled for this release leaving just the basic keyword, identifier, variables, and type highlightings (which is still rather intensive).

This VIM syntax proactively highlights typo errors in RED for:

• nftables configuration file and
• nftables script file

Files having nft in 1st-line shebang will activate the syntax nftables. Files having .nft filetype also will active the syntax nftables as well.

Bug Reporting

If you have any issues with this syntax file, see if you can:

• keep narrowing down the offending line until it stopped offending, hopefully it is just to just one (or few) lines. No need to expose your entire nftables.nft Don't forget to change all IP addresses (unless that breaks too) for your privacy sake.

• post/file the offending line over at my Github issue.

• detail the wrong highlight and state what you think is to be its correct highlight, if applicable.

• Use gist to hold snapshots

Debugging Vim Syntax

If you are bold enough to try your hand on debugging Vim syntax file, see my DEBUG.md on how to debug a Vim syntax file (for the Bind9 named.conf configuration file).

Install

See INSTALL on how to install this Vim syntax to your local Vim settings.

To Vim Developers

Note to Vim developers: During the prototyping of my IPv6 address syntax matching, I noticed that vim 8.1 can only support a maximum of 9 groupings of parenthesis, even if I used the "%( ... )" notation (instead of "( ...)").

As a result of this Vim limitation, I've had to duplicate IPv6 match patterns through this syntax file to get around this vim 8.1 limitation. But it works and faster so.
