I'm developing an applications which I've got running on a server on my linux desktop. Due to the shortcomings of Flash on Linux (read: too hard) I'm developing the (small) flash portion of the app in Windows, which means there's a lot of frustrating back and forth. Now I'm trying to capture the output of the flash portion using flash tracer and that is proving very difficult also. Is there any other way I could monitor the output of trace on linux? Thanks...
Hope this helps too (for the sake of google search i came from):
In order to do trace, you need the debugger version of Flash Player from
http://www.adobe.com/support/flashplayer/downloads.html (look for "debugger" version specifically - they are hard to spot on first look)
Then an mm.cfg file in your home containing
ErrorReportingEnable=1 TraceOutputFileEnable=1 MaxWarnings=50
And then you are good to go - restart the browser. When traces start to fill in, you will find the log file in
~/.macromedia/Flash_Player/Logs/flashlog.txt
Something like
tail ~/.macromedia/Flash_Player/Logs/flashlog.txt -f
Should suffice to follow the trace.
A different and mind-bogglingly simple workaround that I've used for years is to simply create an output module directly within the swf. All this means is a keyboard shortcut that attaches a MovieClip with a textfield. All my traces go to this textfield instead of (or in addition to) the output window. Over the years I've refined it of course, making the window draggable, resizable, etc. But I've never needed any other approach for simple logging, and it's 100% reliable and reusable across all platforms.
[EDIT - response to comment]
There's no alert quite like javascript's alert() function. But using an internal textfield is just this simple:
ACTIONSCRIPT 1 VERSION
(See notes at bottom)
/* import ExternalInterface package */
import flash.external.*;
/* Create a movieclip for the alert. Set an arbitrary (but very high) number for the depth
* since we want the alert in front of everything else.
*/
var alert = this.createEmptyMovieClip("alert", 32000);
/* Create the alert textfield */
var output_txt = alert.createTextField("output_txt", 1, 0, 0, 300, 200);
output_txt.background = true;
output_txt.backgroundColor = 0xEFEFEF;
output_txt.selectable = false;
/* Set up drag behaviour */
alert.onPress = function()
{
this.startDrag();
}
alert.onMouseUp = function()
{
stopDrag();
}
/* I was using a button to text EI. You don't need to. */
testEI_btn.onPress = function()
{
output_txt.text = (ExternalInterface.available);
}
Notes: This works fine for AS1, and will translate well into AS2 (best to use strong data-typing if doing so, but not strictly required). It should work in Flash Players 8-10. ExternalInterface was added in Flash 8, so it won't work in previous player versions.
ACTIONSCRIPT 3 VERSION
var output_txt:TextField = new TextField();
addChild(output_txt);
output_txt.text = (String(ExternalInterface.available));
If you want to beef it out a bit:
var alert:Sprite = new Sprite();
var output_txt:TextField = new TextField();
output_txt.background = true;
output_txt.backgroundColor = 0xEFEFEF;
output_txt.selectable = false;
output_txt.width = 300;
output_txt.height = 300;
alert.addChild(output_txt);
addChild(alert);
alert.addEventListener(MouseEvent.MOUSE_DOWN, drag);
alert.addEventListener(MouseEvent.MOUSE_UP, stopdrag);
output_txt.text = (String(ExternalInterface.available));
function drag(e:MouseEvent):void
{
var alert:Sprite = e.currentTarget as Sprite;
alert.startDrag();
}
function stopdrag(e:MouseEvent):void
{
var alert:Sprite = e.currentTarget as Sprite;
alert.stopDrag();
}
[/EDIT]
If you only need the trace output at runtime, you can use Firebug in Firefox and then use Flash.external.ExternalInterface to call the console.log() Javascript method provided by Firebug.
I've used that strategy multiple times to a large degree of success.
Thunderbolt is a great logging framework with built-in firebug support.
I use the flex compiler on linux to build actionscript files, [embed(source="file")] for all my assets including images and fonts, I find actionscript development on linux very developer friendly.
Then again, I'm most interested in that flash has become Unix Friendly as aposed to the other way around :)
To implement FlashTracer, head to the following address and be sure you have the latest file. http://www.sephiroth.it/firefox/flashtracer/ . Install it and restart the browser.
Head over to adobe and get the latest flash debugger. Download and install the firefox version as FlashTracer is a firefox addition.
Now that firefox has the latest flash debugger and flash tracer we need to locate mm.cfg
Location on PC: C:\Documents and Settings\username
Inside of mm.cfg should be:
ErrorReportingEnable=1
TraceOutputFileEnable=1
MaxWarnings=100 //Change to your own liking.
Once that is saved, open firefox, head to the flash tracer window by heading to tools > flash tracer. In the panel that pops up there is two icons in the bottom right corner, click the wrench and make sure the path is set to where your log file is being saved. Also check to see that flash tracer is turned on, there is a play/pause button at the bottom.
I currently use this implementation and hope that it works for you. Flash Tracer is a little old, but works with the newest versions of FireFox. I am using it with FireFox 3.0.10.

I'm trying to create a utility that will selectively hide and show windows based on pre-assigned hotkeys and I'm working with the Windows API code.
I use a FindWindowW call to get a handle to a window as a test (in my case, a window with the text "Calculator - Calculator", which matched an open calculator window) and use that handle in a ShowWindow function.
Code below:
var user32path = 'C:\\Windows\\System32\\user32.dll';
function TEXT(text){
return new Buffer(text, 'ucs2').toString('binary');
}
var user32 = new FFI.Library(user32path, {
'FindWindowW': ['int', ['string', 'string']],
'ShowWindow': ['int', ['int', 'int']],
'ShowWindowAsync': ['int', ['int', 'int']],
'FindWindowExW': ['int', ['int', 'int', 'string', 'string']],
'BringWindowToTop': ['int', ['int']],
'GetActiveWindow': ['int', ['int']]
var handle = user32.FindWindowW(null,TEXT("Calculator - Calculator"));
user32.ShowWindow(
handle, 'SW_Hide');
//associatedWindowHandle is a manually-created variable with the Spy++ variable.
//The Spy++ doesn't match and I'm not sure why.
user32.ShowWindowAsync(activeHandle, 'SW_Hide');
var pruneLength = Object.keys(prunedData).length;
for (let i = 0; i < pruneLength-1; i++){
if (Object.entries(prunedData)[i][1] === hotkey){
for(let j = 1; j <= prunedData.assocWindows.length; j++){
let associatedWindow = Object.entries(prunedData)[i+1][j].toString();
let associatedWindowHandle = parseInt(associatedWindow);
user32.ShowWindowAsync(associatedWindowHandle, 'SW_Hide');
user32.BringWindowToTop(associatedWindowHandle[i+1][j]);
}
}
}
2 main issues:
When I try hiding and/or minimizing the open calculator window, I can't seem to show it again when clicking on it. the preview image disappers and I notice a "Process Broker" is thrown.
I can't seem to actually find the window handle given with tools like Spy++, which makes it somewhat hard to debug to see if I need to grab a different handle. The parent-level calculator window's handle doesn't seem to match, and I verified that it was the same tool.
I'd also like to be pointed to some decent resources to help self-educate on this so I can better troubleshoot this in the future.
Many thanks!
Firstly, I'd echo Hans Passant's remarks that you're probably better off not trying to so this with a UWP app like Calculator, but then again these apps are not going to go away so perhaps you might want to try anyway.
The shell doesn't appear to appreciate you trying to hide a UWP app (Win32 apps work fine though, go figure). As you have observed, it's icon remains visible in the toolbar but behaves strangely while the window is hidden. So, short version, don't do that.
Instead, try this:
PostMessage (hWnd, WM_SYSCOMMAND, SC_MINIMIZE, 0);
Then things work a lot better, although the user can still undo all your good work by reopening the window of course.
As for Spy++, I have no trouble locating the top-level window of a UWP app using the 'Finder tool' (Menu -> Search -> Find Window). You just have to walk a couple of levels up the window hierarchy afterwards until you get to the one you really want.
Spy++ seems not to be able to log messages being sent to such a window however, see (shameless plug): Why can't Spy++ see messages sent to UWP apps?. I plan to look into this a bit more when I have time.
Finally, what do you mean by 'a "Process Broker" is thrown' please? I don't understand that comment. There's something called RuntimeBroker, which shows up in Process Explorer and appears to be connected with UWP apps in some way, but I don't know if that's what you mean and and I don't know anything about it even if you did.
I am currently building an electron app. I have a PDF on my local file system which I need to silently print out (on the default printer). I came across the node-printer library, but it doesn't seem to work for me. Is there an easy solution to achieve this?
Well first of all it is near impossible to understand what you mean with "silent" print. Because once you send a print order to your system printer it will be out of your hand to be silent at all. On Windows for example once the order was given, at least the systemtray icon will indicate that something is going on. That said, there are very good described features for printing with electron even "silent" is one of them:
You need to get all system printers if you do not want to use the default printer:
contents.getPrinters()
Which will return a PrinterInfo[] Object.
Here is an example how the object will look like from the electron PrtinerInfo Docs:
{
name: 'Zebra_LP2844',
description: 'Zebra LP2844',
status: 3,
isDefault: false,
options: {
copies: '1',
'device-uri': 'usb://Zebra/LP2844?location=14200000',
finishings: '3',
'job-cancel-after': '10800',
'job-hold-until': 'no-hold',
'job-priority': '50',
'job-sheets': 'none,none',
'marker-change-time': '0',
'number-up': '1',
'printer-commands': 'none',
'printer-info': 'Zebra LP2844',
'printer-is-accepting-jobs': 'true',
'printer-is-shared': 'true',
'printer-location': '',
'printer-make-and-model': 'Zebra EPL2 Label Printer',
'printer-state': '3',
'printer-state-change-time': '1484872644',
'printer-state-reasons': 'offline-report',
'printer-type': '36932',
'printer-uri-supported': 'ipp://localhost/printers/Zebra_LP2844',
system_driverinfo: 'Z'
}
}
To print your file you can do it with
contents.print([options])
The options are descriped in the docs for contents.print():
options Object (optional):
silent Boolean (optional) - Don’t ask user for print settings. Default is false.
printBackground Boolean (optional) - Also prints the background color and image of the web page. Default is false.
deviceName String (optional) - Set the printer device name to use. Default is ''.
Prints window’s web page. When silent is set to true, Electron will pick the system’s default printer if deviceName is empty and the default settings for printing.
Calling window.print() in web page is equivalent to calling webContents.print({silent: false, printBackground: false, deviceName: ''}).
Use page-break-before: always; CSS style to force to print to a new page.
So all you need is to load the PDF into a hidden window and then fire the print method implemented in electron with the flag set to silent.
// In the main process.
const {app, BrowserWindow} = require('electron');
let win = null;
app.on('ready', () => {
// Create window
win = new BrowserWindow({width: 800, height: 600, show: false });
// Could be redundant, try if you need this.
win.once('ready-to-show', () => win.hide())
// load PDF.
win.loadURL(`file://directory/to/pdf/document.pdf`);
// if pdf is loaded start printing.
win.webContents.on('did-finish-load', () => {
win.webContents.print({silent: true});
// close window after print order.
win = null;
});
});
However let me give you a little warning:
Once you start printing it can and will get frustrating because there are drivers out there which will interpret data in a slightly different way. Meaning that margins could be ignored and much more. Since you already have a PDF this problem will most likely not happen. But keep this in mind if you ever want to use this method for example contents.printToPDF(options, callback). That beeing said there are plently of options to avoid getting frustrated like using a predefined stylesheet like descriped in this question: Print: How to stick footer on every page to the bottom?
If you want to search for features in electron and you do not know where they could be hidden, all you have to do is to go to "all" docs and use your search function: https://electron.atom.io/docs/all/

I recently published NPM package to print PDF files from Node.js and Electron. You can send a PDF file to the default printer or to a specific one. Works fine on Windows and Unix-like operating systems: https://github.com/artiebits/pdf-to-printer.
It's easy to install, just (if using yarn):
yarn add pdf-to-printer
or (if using npm):
npm install --save pdf-to-printer
Then, to silently print the file to the default printer you do:
import { print } from "pdf-to-printer";
print("assets/pdf-sample.pdf")
.then(console.log)
.catch(console.error);
To my knowledge there is currently no way to do this directly using Electron because while using contents.print([]) does allow for 'silently' printing HTML files, it isn't able to print PDF views. This is currently an open feature request: https://github.com/electron/electron/issues/9029
Edit: I managed to work around this by converting the PDF to a PNG and then using Electron's print functionality (which is able to print PNGs) to print the image based view. One of the major downsides to this is that all of the PDF to PNG/JPEG conversion libraries for NodeJS have a number of dependencies, meaning I had to implement them in an Express server and then have my Electron app send all PDFs to the server for conversion. It's not a great option, but it does work.
I am using the https://github.com/mikaelbr/node-notifier package to show notifications in shell.
This is my code:
var notifier = require('node-notifier');
var path = require('path');
notifier.notify({
title: 'My awesome title',
message: 'Hello from node, Mr. User!',
icon: path.join(__dirname, 'coulson.jpg'), // absolute path (not balloons)
sound: true, // Only Notification Center or Windows Toasters
wait: true // wait with callback until user action is taken on notification
}, function (err, response) {
// response is response from notification
});
notifier.on('click', function (notifierObject, options) {
// Happens if `wait: true` and user clicks notification
});
notifier.on('timeout', function (notifierObject, options) {
// Happens if `wait: true` and notification closes
});
The notification comes like this:
As you can see a terminal icon is coming before the name.
Can you help me how to remove that icon?
It is known issue with node-notifier.
From issue #71:
mikaelbr:
No, I'm afraid that's how the notification work, as it's the terminal that initiates the message. The only way to avoid this is to use your custom terminal-notifier where the Terminal icon is swapped for your own. It's not a big task, and you can easily set customPath for notification center reporter.
kurisubrooks:
This happens because of the way notifications in OS X work. The notification will show the referring app icon, and because we're using terminal-notifier to push notifications, we have the icon of terminal-notifier.
To work around this, you'll need to compile terminal-notifier with your own app.icns. Download the source, change out the AppIcon bundle with your own in Xcode, recompile terminal-notifier and pop it into node-notifier. (/node-notifier/vendor/terminal-notifier.app)
Now that you have your own terminal-notifier inside node-notifier, remove all the icon references from your OS X Notification Center code, and run the notification as if it has no icon. If the old app icon is showing in your notifications, you need to clear your icon cache. (Google how to do this)
Another valuable comment from mikaelb:
That's correct. But keep in mind, node-notifier uses a fork of terminal-notifier (github.com/mikaelbr/terminal-notifier) to add option to wait for notification to finish, so this should be used to add your own icon. A easy way to do it is to copy/paste from the vendor-folder and use customPath to point to your own vendor.
I tried #Aleksandr M's steps but it didn't seem to work for me. Maybe I didn't understand the steps well enough. Here's how it worked for me.
I cloned https://github.com/mikaelbr/terminal-notifier . Then opened the project with xcode and deleted the Terminal.icns file and replaced it with my custom icon Myicon.icns.
Then edited terminal-notifier/Terminal Notifier/Terminal Notifier-Info.plist by setting the key icon file to Myicon.
After doing this, simply building the project did NOT work. I had to change the values of the build version and build identifier (any new value would do) see this.
Afterwards I just built the project with xcode and then copied the built .app file (you can find it by clicking the Products directory of the project from xcode Products > right click the file > show in finder) to my electron project
e.g your final path may look like this. electron-project/vendor/terminal-notifier.app.
Then I set customPath as #Aleksandr M suggested.
Here's what mine looked like
var notifier = new NotificationCenter({
customPath: 'vendor/terminal-notifier.app/Contents/MacOS/terminal-notifier'
});
And THEN it worked! 🙂
This solved my problem and you only need to have your icns file ready:
run this command in terminal after downloading :customise-terminal-notifier
** path/customise-terminal-notifier-master/customise-terminal-notifier -i path/Terminal.icns -b com.bundle.identifier
This may be a simple one but I can't figure it out. How can I open a web page in the main browser from extendscript as I would do with window.open() in Javascript?
I am targeting After Effects and would like it to work on both OS X and Windows.
In After Effects you can simply do it using the system object, as Dirk mentioned. However you need several things for that:
checking that the script can access the network:
if (app.preferences.getPrefAsLong("Main Pref Section", "Pref_SCRIPTING_FILE_NETWORK_SECURITY") != 1)
{
alert("Please tick the \"Allow Scripts to Write Files and Access Network\" checkbox if Preferences > General");
// Then open Preferences > General to let people tick the checkbox
app.executeCommand(2359);
// Here you should check again if they ticked it, and choose to continue or stop ...
}
checking of the OS:
var os = system.osName;
if (!os.length)
{
// I never remember which one is available, but I think $.os always is, you'll have to check
os = $.os;
}
app_os = ( os.indexOf("Win") != -1 ) ? "Win" : "Mac"
os-dependent system calls:
var url = "http://aescripts.com";
if ( app_os == "Win" )
{
system.callSystem("explorer " + url);
}
else
{
system.callSystem("open " + url);
}
Provided you have access to CSInterface.js:
cep.util.openURLInDefaultBrowser("http://www.google.com")
One application independent way is to write an operating system's representation of the URL into a file, then execute() the file.
On the Mac that would be a .webloc file. The underlying format is "plist binary", if you prefer to generate xml, create a sample webloc by drag&drop from the browser address and convert it:
plutil -convert xml1 ~/Desktop/sample.webloc
To invoke that webloc, run the ExtendScript
File("~/Desktop/sample.webloc").execute()
You can do anything on your local computer - commandline and anything else in a VBS file, and you can launch a vbs file from javascript like this:
function RunScriptVBS(whatscriptname){
app.doScript(File(whatscriptname), ScriptLanguage.VISUAL_BASIC);
}
Here is your vbs script:
Dim objShell
Set objShell = CreateObject("WScript.shell")
objShell.Run ("http://www.somewhere.com")
set objShell = nothing
The scope of the question apparently has been refined to After Effects (AE), so I add another answer specific to that application.
On my Machine AE CS6 does not produce an object model file for display by the ExtendScript Toolkit. Please retry it yourself, the object model viewer is in the help menu of ESTK.
Anyway, the ESTK data browser does works. If you target AE, you'll see a couple of objects and classes. Eventually check some more menu items in the databrowser panel flyout menu. I had a deeper look at the app object itself (no openUrl() there) and also found a "system" object. Expand that and you see several interesting methods.
The following script opens a URL on the Mac. I have not tried Windows, maybe it is even the same.
system.callSystem("open http://www.google.com")
As this is the first time I launched AfterEffects, I might have missed better ways.
I would like to create a simple add-on that would play a different MP3 recording every time the user double clicks a word in a webpage he is visiting and selects a special option from the context menu.
The MP3 files are located on a remote server. Normally I would use JavaScript+Flash to play the MP3 file. In a Firefox add-on, however, I'm unable to load external scripts for some reason (playing the sound works fine if it's the webpage itself that loads the scripts, but of course I need it to work with every website and not just the ones that include the script).
So what's the easiest way to play a remote MP3 file in a Firefox add-on using JavaScript?
This may not entirely solve your question, as I don't BELIEVE it plays MP3s, but I'm not certain.
Firefox has nsISound, which I KNOW can play remote WAV files, as I've tested and proved it.
You may want to test it for yourself and see if it leads you a little closer!
var ios = Components.classes['#mozilla.org/network/io-service;1'].getService(Components.interfaces.nsIIOService);
var sound = ios.newURI("http://www.yoursite.com/snds/haha.wav", null, null);
var player = Components.classes["#mozilla.org/sound;1"].createInstance(Components.interfaces.nsISound);
player.play(sound);
Good luck, I hope this at least gets you close!
I know this is an old question, but if someone needs a way to do it:
let player = document.createElement("audio");
player.src = browser.runtime.getURL(SOUND_URL);
player.play();
There is one caveat: the user must have allowed autoplay on the website.
Here is a working code....
var sound = Components.classes["#mozilla.org/sound;1"].createInstance(Components.interfaces.nsISound);
var soundUri = Components.classes['#mozilla.org/network/standard-url;1'].createInstance(Components.interfaces.nsIURI);
soundUri.spec = "chrome://secchat/content/RING.WAV";
sound.play(soundUri);
var window = require('sdk/window/utils').getMostRecentBrowserWindow();
var audio = ('http://example.com/audio.mp3');
audio.play();
