Objective-C Send arguments from terminal when cocoa app is already launching - objective-c

I'm trying to pass some arguments to an UI-based program (cocoa app) through terminal commands while the app is already in launch.
For example:
open appName.app -openUI // Shows App UI
open appName.app -forceQuit 5 // Force quit App after 5 seconds
open appName.app -sendMsg "Hello World." // Add "Hello World" to UNUserNotificationCenter
I will be very grateful if someone can guide me how to implement this, thank you.

If you specify the arguments in that way, they will be send to the open command - which does not recognize them.
You need to put a --args in front of them in order to tell open to pass all the follwing arguments to the app launched, e.g.
open appName.app --args -openUI
Update
If the app is already running, open will use the running app. If you want to create a new window, you need to provide the -n parameter:
open appName.app -n --args -openUI

Reload a React Native app on an Android device manually via command line

I'd like to manually force a Reload of my React Native app on demand without physically shaking the device. (I'm getting carpal tunnel.)
I know that Live Reload / Hot Reload are available. I'm looking for a on-demand command line solution.
Using the cmd line you can send a command to the Android device.
adb shell input text "RR"
This command tells the Android device to type the character "R" twice which is the React Native command to Reload on Android.
The adb shell command has many useful features many of which are described here:
ADB Shell Input Events
To open the developer menu:
adb shell input keyevent 82
Just posting it here in case you didn't know this trick
long press the menu button in your android device. Then you'll get this menu
tap the reload option and you are good to go
I use the following command. It doesn't reload the app, but it brings up the developper menu on the device, so I can then press the "Reload" option:
adb shell input keyevent KEYCODE_MENU
I develop with a real device (not the emulator) and sending the "double-R" through adb doesn't work (it just shows the keyboard and types 2 Rs).
Add the following script to your package.json:
"android-shake": "adb shell input keyevent 82"
Then you will be able to call
yarn android-shake
If you are looking for ios then checkout my answer on this link
One trick would be to add this command on ~/.bashrc profile in the case you're using unix.
use your favorite editor (ex: nano on Ubuntu) and type nano ~/.bashrc
on the end of file write alias rnreload='adb shell input text "RR"'
save it and run source ~/.bashrc in order to active it.
Now whenever you need, just type rnreload on a terminal.
Next time you enter your computer it should be already done.
Also, there's the possibility to add an other alias as well: alias rnshake='adb shell input keyevent 82' which "shakes" android. You can use it to access other commands like Hot Reloading, Debugger, Inspector, etc.
Made an autohotkey script to reload and open the menu with keyboard shortcuts.
^+r:: run, %comspec% /c adb shell input text "RR",,hide
^+e:: run, %comspec% /c adb shell input keyevent 82,,hide
ctrl+shift+r to reload
ctrl+shift+e to open dev menu
If you're on a Mac and using Hammerspoon, you can put the following bit of code in your ~/.hammerspoon/init.lua file:
hyper = {'ctrl', 'alt', 'cmd'}
placid = {'ctrl', 'cmd'}
-- React native reload JS on connected device
hs.hotkey.bind(placid, 'R', function()
os.execute('/Users/peter/Library/Android/sdk/platform-tools/adb shell input text "RR"')
end)
-- React native show dev menu on connected device
hs.hotkey.bind(hyper, 'R', function()
os.execute('/Users/peter/Library/Android/sdk/platform-tools/adb shell input keyevent 82')
end)
the os.execute command doesn't load your ENV (doing so would make running commands really slow), so make sure to run which adb in your terminal to figure out what the exact path to adb is. (in my case it was /Users/peter/Library/Android/sdk/platform-tools/adb).
Now you can reload your app using ctrl+cmd+R and show the dev menu using ctrl+option+cmd+R from anywhere and without even bothering to cmd-tab out of your favorite editor!
For device you have just to shake your device than a menu appears so click on Reload

File.execute() is not executing my script. How to debug this issue?

I'm writing a script for Illustrator CS6 in ExtendScript. At the end of my script, I want to spawn a task (a second script, in Ruby) using File.execute(). However, it's not working. And I'm at a loss as how to debug the problem -- how can I figure out why this isn't working?
Here's the end of my ExtendScript file:
// Do a bunch of other work, then:
var rubyFile = new File(scriptFolder + 'BuildHtmlWalkthrough.rb');
alert(rubyFile.exists);
var result = rubyFile.execute();
alert(result);
Both rubyFile.exists and result are always true, indicating that the script launched OK. But the script does not appear to run, at all. I've tried the following diagnostics:
The Ruby script does successfully run from the command line. The script's permissions are -rwxr-xr-x
I added a call to system("touch /blah/blah/blah") as the very first line of the Ruby script. The file does not get touched.
I thought maybe the ExtendScript process was terminating before the Ruby script could run, so I added a long for loop after rubyFile.execute(). Spinning for > 30 seconds did not help.
What can I do to debug, or solve, this problem?
I'm on MacOS X v10.9.1. And for reference, this is the documentation for File.execute():
File.execute (): Boolean
Core JavaScript Classes
Executes or opens
this file using the appropriate application, as if it had been
double-clicked in a file browser. You can use this method to run
scripts, launch applications, and so on. Returns true immediately if
the application launch was successful.
It's probably doing the "opens this file using the appropriate application" instead of executing, and returns true because the file successfully opens (or is already open in its associated app). If I have a python script and do
f= new File("~/Documents/misc_scripts/getpixelrgb.py");
f.execute();
, it opens it in my script editor, even if the file's execute flags are set.
I'm on OSX, btw
In After Effects, there is system.callSystem() to execute command line commands, but I'm afraid that is absent in Illustrator (I'm assuming you're doing this for Illustrator because of the tag). Are you on OSX or Windows? There are ways around this, by making an executable .app (OSX) or .exe (Win) and calling that with execute(). If I were doing this, I'm on OSX and I'd make an AppleScript app that does 'do shell script' to make the ruby system call. On Windows, it's different. One solution you might like if you're on windows: ocra, which is ruby-specific (http://ocra.rubyforge.org/). It may be possible to run a .bat file on Windows that calls the ruby script, but I'm not sure.
[edit!]
Terribly sorry for the extraneous Windows info (for someone else, I guess). Just saw your note about being on OSX. So you might want to use the AppleScript solution.
[edit again]
So, if my ruby script ("test.rb") is:
#!/usr/bin/env ruby
print "Hello"
and my AppleScript is:
do shell script "cd /testing_folder/; ruby test.rb"
Then I get "Hello" returned in AppleScript, but ExtendScript will just return true.

Unable to find running application in Cocoa

I am getting the list of running applications in Cocoa with the following code:
for (NSRunningApplication *app in [[NSWorkspace sharedWorkspace] runningApplications]) {
MNSLog(#"%#",[app localizedName]);
}
However an application I started from a terminal session is not appearing in the list ('Terminal' is well appearing). The application was started from the same user which is executing the cocoa code.Is my launched application under Terminal ? And in such a case how can I find its name and arguments ?Running ps in another terminal session show my process properly.
Use an NSTask to execute the ps Shell command. You can check the ps man page to determine which arguments you want to pass it based on the information you want to get back. Use NSPipe and NSFileHandle to get the results from the task.
If you want to do some filtering you can pipe the ps output through grep before your app picks up the result.
For your first question, I think NSWorkspace can only see apps that use the window server so you will only see Terminal, not the executables that it is running internally.
You can use sysctl or ps command to get a list of all BSD processes. Have look at unable to detect application running with another user

Using applescript to run terminal and passing a argument to compile

I am new to applescripts and i want to automate a little bit of my app.So here is the thing
1) I am using textwrangler as an editor
2) After writing code and saving it i want to compile the file by opening terminal from applescript.I already installed llvm compiler.
3) As textwrangler provides me the a menu in meubar to open script editor so after opening it i am using "tell application "Terminal" to activate" it opens terminal
4) i want " gcc myfilename.c " to be passed as argument from applescript so that as soon terminal opens this string should be passed as argument and executable is generated
Can i Do that through scripts? Please help.
Give this a try:
tell application "Terminal" to do script "gcc myfilename.c"
Running this without the Activate line you mentioned will still open Terminal if it isn't already open, but it won't bring it to the front. For that, Just turn the whole thing into a tell block and put the Activate back in there so it becomes:
tell application "Terminal"
activate
do script "gcc myfilename.c"
end tell

Different ways to Launch MAC OSX objective C opplication from command line

I have a MAC OSX objective C application say first.app ,in which i use NSAppleScript with admin privileges to run a shell script.This script is indented to launch another Objective C application say second.app.
When you use open command Ex: "open second.app" in shell script it works fine .
But if you launch the second.app by calling its binary Ex: "/second.app/Contents/MacOS/second " in shell script ,then the control don't come back to first.app until second.app closes . when we close the second.app then first.app resumes .
What is the difference in launching the application from open command and calling the applications binary directly as mentioned ?
Calling
open Second.app
is the same as double-clicking the app's icon in the Finder. The application is started via LaunchServices, and the open command returns immediately.
Calling
/path/to/Second.app/Contents/MacOS/Second
starts the application directly (without LaunchServices), and returns only when the application has terminated.
