Chaging adhearsion config with out restarting adhearsion application

[Vijay]

Hi,

I would like to know if running Adhearsion application config can be changed without restarting the application.  

I understand that SIGALRM can be used to toggle on or off TRACE level logging. Similarly, can any other signal can be used to force the Adhearsion application to re read the config.

Thanks 

Vijay

Hello Vijay,

My suggestion would be to consider adding http endpoints to your adhearsion application to allow you to manipulate various config settings of the Adhearsion core config as well as for Adhearsion plugins.

The Virginia gem allows you to easily bolt-on a Reel based web server to Adhearsion.  Any endpoints you add to Virginia will be running in the same process as Adhearsion, and thus can easily manipulate configuration.

Virginia supports any rack-based web framework.  Here's an example endpoint using Sinatra:

require 'sinatra/base'

put '/default_voice' do

  Adhearsion.config.media.default_voice = params[:default_voice] if params[:default_voice]

  standard_response "default_voice changed to #{Adhearsion.config.media.default_voice}.\n"

end

# Sinatra helpers

helpers do

  def standard_response(response, status_code = 200, headers = {})

    [status_code, headers, [response]]

  end

end

You could invoke this externally using a program like cURL like so:

curl -f -s -S -H 'Accept: application/json' -X PUT -d 'default_voice=Larry' http://localhost:8080/default_voice

#=> default_voice changed to Larry.

Hello,

additionally, the current version fo Adhearsion 3 (release coming soon, I promise!) bundles a more advanced version of the HTTP server right in the main library. You can just add your actions to config.ru in the familiar Sinatra syntax.

Best regards,

Luca

Awesome, I did not knew that it works that way; only use Virginia to add api capabilities
