##Lava, the burning suite for Haiku OS License: MIT
Authors: Jan64, Negr0, GenKi, SprMa, FinN, stargater

###The components

LibBurnDevice - Doing the actual burning, a library accessing cdrecord etc.

Lava - The Tracker add-on

BurnDevice - The preference panel

###The basic idea GUI <-------> LibBurnDevice <------> cdrecord/libburn
LibBurnDevice is a class to easily access cdrecord and other tools. Any GUI application, Tracker add-on etc. only needs to know this one class and won't have to deal with the gory details of burning.

###The architecture

####Project management
There's no real application for project management planned. Projects are stored in a folder in the filesystem (e.g. /boot/home/burn/) with subfolders representing the different projects (e.g. /boot/home/burn/project-1). These subfolders in turn contain for every added file an empty file with attributes holding information about the added file, see Jan's suggestion on Caspar-Wendy-Style. Unwanted files can simply be removed from the project folder.

If the Tracker add-on is invoked on a file, a dialog opens to decide to which project the file should be added or if a new project should be created for it. A new project automatically creates a folder in /boot/home/burn/.

####Add-on The Tracker add-on is used to add files to a project. It's dialog shows a list of all files in the project and a button to start the burning. If you choose not to burn and just close the window, you can continue to add more files to this project.

####Burning Besides using the button in the add-on after adding files to start the burning, you can also invoke the add-on on a project folder at a later time.

###Short introduction to LibBurnDevice LibBurnDevice's goal is to keep the burning as simple as possible. Still, there are a few useful methods that need some explaining:

  • The constructor BurnDevice() sets all burning option to default values, checks the version of cdrecord and gets information on all available burning devices. It doesn't set a device yet, however!
  • For that, you invoke GetBurnDevices() which returns a BList with pointers to objects of the type burn_device.
  • A burn_device holds strings with information to: device number, manufacturer, device name, additional name.
  • With SetBurnDevice() you then set a device of this list as default device.
