Getting started with Lua

Enabling Lua (via mod_lua) is very similar to the process we used in Chapter 2, Building and Installation, where we enabled mod_flite. It is done in the following way:

1. Open modules. conf in the FreeSWITCH source directory and locate the following line:

   #languages/mod_lua

   Remove the # and save the file.

2. Open modules.conf. xml in the conf/autoload_configs directory and locate the following line:

   <!-- <load module="mod_lua"/> -->

   Remove the <!-- and --> tags and save the file.

3. Build and compile mod_lua from the FreeSWITCH source directory:

   make mod_lua-install
   

4. Wait for the installation to finish, and then restart FreeSWITCH. Launch fs_cli and type show application. If Lua loaded successfully, then you will see that lua is now available as a Dialplan application as follows:

   lua,Launch LUA ivr,<script>,mod_lua
   

You are almost ready to write scripts in Lua.

Note

Later versions of FreeSWITCH have mod_lua enabled by default.
