Call OS commands via scripting

[SimonBjörk]

Is there a way to call OS commands via the Premiere scripting API?

Basically I would like to run a python script from within premiere, but I see no way to call a os command.

After Effects has the system.callSystem method, which could look something like this:

cmd = "from sb_pipeline import folderStructure; print folderStructure()"

// Call the python script.

var s = system.callSystem('python -c ' + '"' +  cmd + '"');

alert(s);

Not via ExtendScript, but PPro panels can send command lines to the OS.

Thanks Bruce.

Still I'm not really sure how to use this (note that I haven't been digging in to the panels yet).

Could you post a sample code where it calls a file from the command line?

From that web page:

//create folder /tmp

var result = window.cep.process.createProcess(‘/bin/mkdir’,’/tmp');

Yeah, but what about starting an application for example? Can I run a command just like I do in the terminal/command prompt? For examnple like this: window.cep.precess.createProcess("C:\Program Files\Adobe\Adobe After Effects CC 2015\Support Files\AfterFX.exe")

Also, I'm not sure how to use this other languege. Are you saying I can just type in the command directly in a panel? Examples? I haven't had time to look into panels yet.

Yes; try it!

It's JavaScript. Yes, you can fire off command lines, from within a panel. See the CEP HTML Test Extension.
