Extending RoughDraft

RoughDraft is built extensibly. This is so that complex FFMpeg operations can be abstracted into small amounts of code.

You can see the current set of extensions with:

Get-RoughDraftExtension

Extension Scripts

Extensions are simple scripts files named with the regular expression \.(rd|RoughDraft)\.(ext|extension)\.ps1$.

They can exist in any module that adds the tag “RoughDraft”.

Extensions should include the following attributes above their parameter block:

# It's an extension
[Runtime.CompilerServices.Extension()]
# that extends Edit-Media            
# (Change this to indicate which command you'd like to extend)
# (Add additional Cmdlet attributes one to extend more commands)
[Management.Automation.Cmdlet("Edit","Media")] 
# that is inherited (this is the default).
# (an extension that is 'Inherited' will return control to the main function when it is done.)
# (an extension that is 'NotInherited' will run and return directly)
[ComponentModel.Inheritance("Inherited")]
param(
# At least one parameter of the extension should be mandatory.
[switch]
$MyEditExtension
)
