ExtendScript as it's implemented in Photoshop Scripting engine is compliant to: - ECMA-262 (version 3) - EX4 (EcmaScript for XML) plus other custom stuff like Filesystem management, Reflection interface, operator overloading, etc. It's a great language, but... the rest of the Javascript world has moved to ECMA-262 version 6 aka ES6 Harmony, while so to speak we're stuck at ES3. We don't have native support (among the rest) of JSON, Array.indexOf, Promises, Object.create, etc... It's becoming increasingly difficult to interface with JS libraries, since shims are not always available/functional. Also, strategically, we're in a cul-de-sac (aka dead end): there hasn't ever been a major language update (besides ScriptUI changes to support different rendering engines over the years), the PS Scripting language cannot not-evolve now that JS seems to have gained a great momentum and it's as lively as it's never been in the past. My feature request is not to substitute ExtendScript with JS tout-court (since it would mean give up to EX4 and proprietary stuff), but to incorporate the new ES6 syntax and features - give ExtendScript a place in the future.

Hello, I've been constantly and repeatably experiencing this error the first 2 times I launch my script. Third and subsequent lauches go smoothly, unless I reboot PS - which moves the situation back to square one (1st launch fails, 2nd launch fails, 3rd is ok).   The script contains, among the rest, a ScriptUI window with embedded graphics - as suggested in the ScriptUI Guide for Dummies I use the following code to serialize PNG icons: function graphic_to_text(infiles /*array of file objects*/ ) { var outfile, s, re1 = /^\(new String\(/, re2 = /\)\)$/; for(var i = 0; i < infiles.length; i++) { if (infiles[i].exists) { outfile = new File(infiles[i].fullName.replace(/\.(png|idrc|jpg)$/, ".txt")); infiles[i].open("r"); infiles[i].encoding = "BINARY"; outfile.open("w"); s = infiles[i].read(); outfile.write(s.toSource().replace(re1, "").replace(re2, ";")); infiles[i].close(); outfile.close(); } } } var file = new File($.fileName); var folder = new Folder(file.path); graphic_to_text(folder.getFiles("*.png")); which I then embed as (looong) strings this way: var zoomFitPNG = "\u0089PNG\r\n\x1A\n\x00\x00\x00\rIHDR\x00\x00\x00\ /* etc. etc. */ \u00AEB`\u0082" win.previewAndProgressGroup.zoomGroup.zoomFitButton.image = zoomInPNG; so far I've never had any problem - strangely enough I'm now getting this error (and this weird pattern of fails and successes). I forgot to mention that when the script runs as it is supposed to do, the graphics are ok. If you're wondering, OSX 10.8.2, PS CS6 (13.0.3). Any suggestion is welcome. Thanks in advance!   Davide ... View more
