## Applications
|
||||
* **programs**: managing stations, programs, schedules and diffusions. This is the core application, that handle most of the work;
|
||||
* **liquidsoap**: generate configuration and controls over liquidsoap. We use one instance of liquidsoap per station;
|
||||
* **controllers**: interface with external stream generators. For the moment only support [Liquidsoap](http://liquidsoap.fm/). Generate configuration files, trigger scheduled diffusions and so on;
|
||||
* **cms**: cms manager with reusable tools (can be used in another website application);
|
||||
* **website**: set of common models, sections, and other items ready to be used for a website;

# Aircox LiquidSoap
|
||||
This application makes the bridge between Aircox and LiquidSoap. It can monitor scheduled and streamed programs and offer some controls on LiquidSoap.
|
||||
|
||||
|
||||
## manage.py's commands
|
||||
* ** liquidsoap **: monitor LiquidSoap, logs what is playing on the different sources, and plays scheduled diffusions;
|
||||
* ** liquidsoap_files**: generates playlists and LiquidSoap config based on Programs' parameters;
|
||||
|
||||
|
||||
## Requirements
|
||||
* Liquidsoap
|
||||
* requirements.txt for python's dependencies

Base configuration file to configure a station on liquidsoap.
|
||||
|
||||
A Station is composed of multiple streams, that includes:
|
||||
- controller.dealer: used to play scheduled programs;
|
||||
- controller.streams: streams configured to play random sounds;
|
||||
|
||||
# Interactive elements:
|
||||
An interactive element is accessible to the people, in order to:
|
||||
- get metadata
|
||||
- skip the current sound
|
||||
- enable/disable it, only for the dealer
|
||||
|
||||
- {controller.id}: the station itself
|
||||
- {controller.id}_streams: all the streams of a controller
|
||||
- {source.id}: for each stream of a controller + dealer
|
||||
|
||||
|
||||
# Element of the context
|
||||
We use theses elements from the template's context:
|
||||
- controller: controller describing the station itself
|
||||
- settings: global settings
|
||||
|
||||
# Overwrite the template
|
||||
It is possible to overwrite the template, there are blocks at different
|
||||
position in order to do it. Keep in mind that you might want to avoid to
|
||||
put station specific configuration in the template itself.
