Running a Batch or Python Script from TVPaint? Topic is solved

[blastframe]

Hello,
Is it possible to run a Windows Batch or Python Script from TVPaint?

I have tried tv_ReadUserString and tv_ReqFile, but to no avail.

Thanks!

Have you tried:

Code: Select all

tv_plugin iFile "mount"|"open"|"cmd"|"exec"|"about" [iParameters]

Execute a plugin

[PARAMETERS]
iFile                                  filesystempath    The plugin
                                                         Info:
                                                         For path with special characters (like ':'), you need to write
                                                             (to not manage the string as a variable)
                                                             tv_***** ... "c:/Users/Mike/Desktop/myfile.ext" ...
                                                         For path with spaces, you need to write:
                                                             (to manage the path as a single string inside TVPaint Animation)
                                                             tv_***** ... '"'"c:/Users/Mike/Desktop/my file with spaces.ext"'"' ...
                                                             The path (already encapsulated with quote (") is again encapsulated with:
                                                             simple-quote (') quote (") simple-quote (')
"mount"|"open"|"cmd"|"exec"|"about"    enum              The command to call in the plugin
iParameters                            string            The parameters of the command for 'cmd' and 'exec'

[RETURN]
oResult    int    The result status returned by the plugin for each command

Hi Sven,
This seems like a step in the right direction, thank you. I am getting an error from TVPaint however.

Here is my batch file, HelloWorld.bat, that works in Command Prompt:

Code: Select all

ECHO OFF
ECHO Hello World
PAUSE

This is my TVPaint George script:

Code: Select all

tv_plugin "C:/Users/Kevin/Desktop/HelloWorld.bat" open

And this is TVPaint's error message when I run it:

Hello_World_error.png (11.18 KiB) Viewed 3416 times

"C:/Users/Kevin/Desktop/HelloWorld.bat is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support. Error status 0xc000012f"

EDIT: I have looked into this and the only examples I could find were using TVPaint's .dll extension files as plugins. If anyone knows if running a script is possible, please let me know!

Here are three forum links to discussions which might help:

Executing Command Line

Using Python and FFMPEG

You've been very helpful, Sven, thank you.

The first forum link had a very useful snippet (I saw your input on that thread as well ):

Code: Select all

tv_runscript "C:/Users/Kevin/Desktop/HelloWorld.bat"

The other two forum links talked about using Python, but neither explained how to run Python from TVPaint.

Thanks again, Sven, for the help!

When you distill the best TVPaint/GEORGE solution for your purposes, could you take a few minutes to add a summary that demonstrates what you were trying to do and how you solved it, to this thread, for other script writers? THANKS!

This might not work for your purpose, but I've had better luck doing this the other way around.

I have Python scripts that run George scripts instead. That way I can wrap Python code before and after the George script runs. You can run george commands in the Windows commandline by basically calling the TVPaint path and then passing either George commands or scripts as arguments.

eg. "C:/Path/To/TVPaint.exe" "cmd=tv_WriteUserString DeadlineConfig ExportFormat PNG"
eg. "C:/Path/To/TVPaint.exe" "script=C:\Path\To\GeorgeScript.grg"

If that sounds like it could be helpful, I can elaborate further on how it works. But it's been the most reliable way to communicate back and forth with TVPaint and Python.
