====== VEGASPython for Developers ======

===== Introduction =====

VEGAS Pro allows the control of the application via scripting. Scripting provides access to the internal data structures in VEGAS projects that allows you to automate things that you might normally do via the GUI.
VEGAS uses the .NET framework to provide its scripting interface. VEGAS can execute C#, JScript, and Visual Basic script files directly.

PYTHON is an easy to learn powerful programming language that is more and more used for scripting of applications. In the 3D and video editing area some application use already PYTHON for scripting.

Goal of this VEGAS extension is to provide an easy access to VEGAS scripting using PYTHON.

The extension provides two options:
  * an interactive dockable VEGASPython Window
  * executing Scripts located in a specific folder and integrate them into the VEGAS User Interface like other C# Scripts

The FAQ describes the usage of VEGAS scriting for C#. The examples can be easily transfered to VEGASPython. An updated FAQ for VEGASPython will follow soon.

The API describes the C# definition of all VEGAS structures and items that can be accessed. All these items can be accessed in the same way in VEGASPython.

===== VEGASPython Interactive Window =====

VEGASPython includes an interactive window.
VEGASPython interactive window is activated via the 'View' / 'Extensions' tab. 

A VEGAS dockable window opens. The window can float over VEGAS or can be integrated into the VEGAS layout as any other VEGAS window.

The VEGASPython window shows two textboxes:

  * Input PYTHON Commands
  * Output
 
and a menu with two items "File" and "Execute VEGASPython Script".

Python comands are entered in the textbox "Input". Several lines can be entered one after each other. It is possible to copy a complete PYTHON Script from another editor via CTRL+C and CTRL+V.
The PYTHON commands will be executed by clicking on the menu "Execute VEGASPython Script".

All output from PYTHON print statements and all error messages will be shown in the "Output" textbox.

VEGASPython is based on Python 3.7.3 and PythonNet.

The VEGAS API can be accessed directly by using the build-in variable "pyVEGAS".
All VEGAS API items are available.

===== Examples =====
Example for a simple script that can be used in the interactive window:

    import clr
    clr.AddReference('ScriptPortal.Vegas')
    import ScriptPortal.Vegas
    from ScriptPortal.Vegas import *
    # adapt this value to your needs
    maxLength = Timecode.FromString("00:00:04:00")
    # Go through the list of Tracks
    for track in pyVEGAS.Project.Tracks:
        for evnt in track.Events:
            if (evnt.Selected):
                dLength = evnt.Length
                if dLength > maxLength:
                    dLength = maxLength
                dStart = evnt.Start
                evnt.AdjustStartLength(dStart, dLength, True)


----

A script that is used as an extension needs to be included in a function FromVegas. See example below.

    import clr
    clr.AddReference('ScriptPortal.Vegas')
    import ScriptPortal.Vegas
    from ScriptPortal.Vegas import *
    def FromVegas(pyVEGAS):
        # adapt this value to your needs
        maxLength = Timecode.FromString("00:00:04:00")
        # Go through the list of Tracks
        for track in pyVEGAS.Project.Tracks:
            for evnt in track.Events:
                if (evnt.Selected):
                    dLength = evnt.Length
                    if dLength > maxLength:
                        dLength = maxLength
                    dStart = evnt.Start
                    evnt.AdjustStartLength(dStart, dLength, True)
