# nginx.vim

## Description

[Vim](http://www.vim.org/) plugin for [Nginx](http://www.nginx.org)


## Features

The plugin is based on the recent vim-plugin distributed with `nginx-1.12.0` and additionally features the following syntax improvements:

- Highlight IPv4 and IPv6 addresses
- Mark insecure `ssl_protocols` as errors
- Inline template syntax highlight for **ERB** and **Jinja**
- Inline syntax highlight for **LUA**
- Improve integer matching
- Syntax highlighting for `proxy_next_upstream` options
- Syntax highlighting for `sticky` options
- Syntax highlighting for `upstream` `server` options
- More to come!

Furthermore:

- Remove annoying delimiters, resulting in strange word-boundaries

*Note: Also check out [sslsecure.vim](https://github.com/chr4/sslsecure.vim): it supports highlighting insecure SSL/TLS cipher suites and protocols in all your files!*
