Vim plugin for Nginx

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: it supports highlighting insecure SSL/TLS cipher suites and protocols in all your files!

Embedded highlighting for ERB and Jinja templates:

Embedded LUA syntax highlighting:

The plugin comes with useful snippets which can be accessed using e.g. vim-snipmate.

Select a decent cipher for your requirements (all of them can provide SSLLabs A+ ratings)

• ciphers-paranoid<tab>: Even-more-secure ciphers (elliptic curves, no GCM), not compatible with IE < 11, OpenSSL-0.9.8, Safari < 7, Android != 4.4
• ciphers-modern<tab>: High-security ciphers (elliptic curves), not compatible with IE < 11, OpenSSL-0.9.8, Safari < 7, Android < 4.4 (recommended)
• ciphers-compat<tab>: Medium-security ciphers with good compatibility (No IE on WinXP) but TLSv1 and SHA required
• ciphers-old<tab>: Low-security ciphers (using weak DES and SHA ciphers, TLSv1), but compatible with everything but IE6 and Java6
• ssl-options<tab>: Bootstrap secure SSL options

Example:

# High-security ciphers (elliptic curves), less compatibility
# No IE < 10, OpenSSL-0.9.8, Safari < 7, Android < 4.4
ssl_protocols TLSv1.1 TLSv1.2;
ssl_ciphers 'ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256';

Or add a robots.txt file with robots.txt<tab>:

# Tell bots to not index this site
location /robots.txt {
    default_type text/plain;
    return 200 'User-agent: *\nDisallow: /\n';
}

It also has auto-completion for location and server blocks with location<tab> resp. server<tab>, and many more!

• Add useful snippets

• Based on the original nginx-1.12.0/contrib/vim
• IPv4 and IPv6 address highlighting, based on expressions found in this forum post
• Blog post introducing this plugin including some more examples

Just plug it into your favorite Vim package manager:

" Plug
Plug 'chr4/nginx.vim'

" Dein.vim
call dein#add('chr4/nginx.vim')

" Vundle
Plugin 'chr4/nginx.vim'

Optionally, if you like Jinja template syntax highlighting, install lepture/vim-jinja, too.
