how to have the user select a file in the finder and pass it to SF

@dieffe, sorry the first solution I posed would give you the full path of the folder in the front most window, not the path to any file selected in that window.

This script will get you first the first selected file's full path, and then afterwards we extract the different parts composing the path (directory, filename with extension, filename without extension, extension)

var fullPath = decodeURIComponent(sf.appleScript.finder.selection.getItem(0).asItem.path);
var directory = fullPath.split('/').slice(0, -1).join('/');
var filename = fullPath.split('/').slice(-1)[0];
var filenameWithoutExtension = filename.split('.').slice(0, -1).join('.');
var extension = filename.split('.').slice(-1)[0];

log(fullPath);
log(directory);
log(filename);
log(filenameWithoutExtension);
log(extension);
