How to access App::Persistence in REPL console in RubyMotion - read-eval-print-loop

I've saved variables like AuthToken into the App::Persistence store, but I want to debug it. Can I access this through the REPL console?

Absolutely. App::Persistence["AuthToken"] will work just fine in the REPL.
If you want to get all the contents of the persistent store, try App::Persistence.storage.dictionaryRepresentation. Look for the keys that begin with your app identifier (com.yourcompany.Appname_).

Where is CoreData located?

I am writing an app which uses CoreData using NSPersistentContainer to save data.
While I am developing the app, I would like to:
examine the data directly
back up the data
see what happens when I change the bundle id
I assume the data is physically stored somewhere, but I’m not sure where to look.
By default NSPersistentContainer stores the database inside app container under directory Libray/Application Support
To locate the full path, in simulator, you can print the applicationSupportDirectory using urls(for:in:) function of the default FileManager:
print(FileManager.default.urls(for: .applicationSupportDirectory, in: .userDomainMask).first?.path ?? "nil")
If you are running your app on an actual device you can download the application container following this answer.
For sandboxed apps the location goes like this:
~/Library/Containers/…/Data/Library/Application Support/…

How to open chrome app with specific URL through chrome_proxy.exe?

I have a Chrome app that I created with "Create Application Shortcut".
What I need is to open that app with specific url on the same domain.
Example:
chrome_proxy.exe --profile-directory=Default --app-id=xxxxxxxx "https://www.google.com"
Is that possible or any command that achive the same result?
I'm guessing you installed the Chrome app so that the website launches in a standalone window. If this is the case, you can achieve something similar by using the --app command line switch instead.
Eg: chrome_proxy.exe --profile-directory=Default --app="https://www.google.com"
This doesn't strictly open the URL in the existing app, but it does open that specific URL in a standalone window.
Here's the answer what you are looking for.
chrome_proxy.exe --profile-directory=Default --app-id=xxxxxxxx --app-launch-url-for-shortcuts-menu-item="https://youtu.be/dQw4w9WgXcQ"
Using this will work:
chrome_proxy.exe --profile-directory=Default --app-id=xxxxxxxx --app-launch-url-for-shortcuts-menu-item="https://youtu.be/dQw4w9WgXcQ"
It will launch in the special standalone window AND navigate to the specified URL.
Replace xxxxxxxx with the app id (this can be found if you look at the properties of the shortcut it created), but after you create the app this part should already be filled in.
At that point all you need to add is this part:
--app-launch-url-for-shortcuts-menu-item="https://youtu.be/dQw4w9WgXcQ"
Replacing the https:​//youtu.be/dQw4w9WgXcQ part with the full URL of where you would like to navigate to.
Documentation of the argument can be found here.

Flash message require session

I'm trying to use express-flash in a standard web express js app. I don't want to use session, because I want to do the app as stateless as possible, but when I try to use without session, the app show me this error:
req.flash() requires sessions
Can I use express-flash without session? Can I use other alternatives for this kind of messages?
Thanks.
Note: A flash message is a variable stored within a session that is only available once, for the next request. That is if we put a flash variable and renders a page, the flash variable is available but if we render the same (or other) page again the flash variable is not present (it is destroyed).
-- acanimal
Based on this premise, you need to have sessions to use message flashing.
One way I think you can accomplish what you want is to add an item to the request (req) object in your middleware, and then in your controller, check if the key exists. You can then pass a specific message to your template, assuming you're using a template engine or pass it as part of your response.
Hope this helps.

Best way to store a user token in Ruby script

I am developing a Ruby script designed for CLI which is based on a REST API. This API needs a token as credentials in order to recognize the user and allows him to retrieve his informations.
For now, this scripts asks the 30-length token in the console every time it is launched.
Now I'd like to store this token to avoid asking it every time the user wants to use the script. I don't know what the best way is, do I have to create a hidden file, containing the token, or ask the user to store it in an environment variable ?
I wanted to use the environment variable solution, but I don't know if it will work the same way for Windows or Linux.
Compose all approaches. Something like this:
def get_my_token()
if ENV["MY_TOKEN"]
return ENV["MY_TOKEN"]
end
token_path = File.expand_path("~/.my_token") # will be expanded to user's home (Documents or smth) in windows, check it yourself as I don't have running windows around here
if File.exists?(token_path)
return File.read(token_path).strip
end
# resort to asking user for token here
end
ENV should go first - so you'll be able to override your config if needed for some testing purpose. Also note that you can run your script as MY_TOKEN=xxxx ruby my_app.rb as well.

sandbox :get NSData using bookmarkDataWithOptions method of NSURL without NSOpenPanel

I enabled sandbox and I want to create data by bookmarkDataWithOptions.
If the URL is created by NSPanel that work very well. But, If I obtain URL without using NSOpenPanel, the bookmarkDataWithOptions method always return nil. why?
thank about If I want to set a special folder default can read/write without using NSOpenPanel.
How can i do?
Thanks
The main feature of the Sandbox is security. If an application could read/write an arbitrary folder without user permission, the security would be broken.
The App Sandbox Design Guide states clearly:
• Simulation of user input in Open and Save dialogs:
if your app depends on programmatically manipulating Open or Save dialogs to simulate or alter user input, your app is unsuitable for sandboxing.
The only way to achieve something similar, is to add a read/write entitlement to one of the preset directories (Documents, Pictures, Music, etc…). For further documentation, take a look at this guide.
