POHow does one feed a list of files into an app with appscript and Python?

copied!<p>Get your newb-shields up, I'm about to sprinkle you with some.<br> I'm trying to get Photoshop CS4 to open a folderful of JPEG images with AppScript+Python, which could be described like so in BASH: </p> <pre><code>#!/bin/bash for F in `ls ~/Desktop/test`; do open -a "Adobe Photoshop CS4" $F # proceed to mutilate the image appearance done </code></pre> <p>I'm failing at the <code>ls ~/Desktop/test</code> stage. I'd really like to ask Finder to list a folder for me, and feed the result into Photoshop one at a time to process them.<br> A JavaScript equivalent with Adobe's ExtendScript bridge would be: </p> <pre><code>#target photoshop var folder = Folder("~/Desktop/test"); var images = folder.getFiles(); for (var i=0; i < images.length; i++) { if (images[i] instanceof File && images[i].hidden == false) { var doc = app.open(images[i]); // do something to the image here doc.close(SaveOptions.DONOTSAVECHANGES); } } </code></pre> <p>I can get me a <code>document_file</code> object with a horribly silly contraption like <code>x = app('Finder').home.folders['Desktop']().folders['test']().items()[0]</code>, but that turns out to be a really silly object. Trying to <code>app('Adobe Photoshop CS4').open(x)</code> this object will throw an <code>OSERROR: 1230</code>, with a <code>MESSAGE: File/Folder expected</code>. </p> <p><em>(Uh-oh, this <code>document_file</code> actually responds to <code>URL()</code>, so <code>File.makewithurl(x.URL())</code> can be fed into <code>open()</code>)</em></p> <p>Ehm, having solved that, is there a way to actually do this by asking Finder for the list of files in a given folder, specified by a <em>UNIX path</em>? </p>
