% Nginx Configuration Generator

nginx-confgen is a simple preprocessor and macro system for
[nginx](http://nginx.org/) and nginx-like configuration files. It support
variable substitution, macro expansion and using the output of arbitrary
commands to generate config files.

## Example

```bash
pre_set $certdir /etc/nginx-certificates/;

# Fetch the 'resolver' from /etc/resolv.conf
pre_exec $nameserver "grep nameserver /etc/resolv.conf \\
                      | head -n 1 | sed 's/^nameserver //'";
resolver $nameserver;

# Convenient macro to create a HTTPS virtual host
macro vhost $domain @aliases &block {
  server {
    listen [::]:443 ssl;
    server_name $domain @aliases;

    ssl_certificate     $certdir/$domain/fullchain.pem;
    ssl_certificate_key $certdir/$domain/privkey.pem;
    pre_if -f $certdir/$domain/ocsp.der {
      ssl_stapling_file $certdir/$domain/ocsp.der;
    }

    █
  }
}

vhost example.com www.example.com {
  root /var/www/example.com;
}
```
