Hi, several months ago I adjusted uwsgi script to load most of its
configuration from INI file instead of rc.conf file. It utilizes all of
uwsgi properties this way.

Do you think it is worth posting it to make available to greater audience?

I called it uwsgiini.

Here is the source code:


#!/bin/sh
#
# PROVIDE: uwsgiini
# REQUIRE: DAEMON
# KEYWORD: shutdown
#
# Add the following lines to /etc/rc.conf to enable uwsgi:
#
# uwsgiini_enable (bool): Set it to "YES" to enable uwsgi
# Default is "NO".
#
# If you would like to have multiple uWSGI instances running, you can
# define multiple profiles:
#
# uwsgiini_profiles (str): Set the list of uwsgi profiles
# Default is "".
#
# For each profile you can then define different options (except for
# uwsgiini_enable) using the syntax uwsgi_<profile>_<option>

. /etc/rc.subr

name="uwsgiini"
rcvar=uwsgiini_enable

load_rc_config $name

command=/usr/local/bin/uwsgi
: ${uwsgiini_enable="NO"}
: ${uwsgiini_apps=""}
: ${uwsgi_pidfile="/tmp/uwsgi.pid"}

: ${uwsgi_socket="/tmp/uwsgi.sock"}

is_uwsgi_app() {
    local app

    for app in $uwsgiini_apps; do
        if [ "$app" = "$1" ]; then
            return 0
        fi
    done

    return 1
}

if [ -n "${uwsgiini_apps}" ]; then
if [ -n "$2" ]; then
app="$2"
if ! is_uwsgi_app $app; then
echo "$app: no such app defined in uwsgiini_apps."
        exit 1
fi

elif [ -n "$1" ]; then

            echo "Processing ${name} app: ${app}"
