Has anyone used JSBox (a JavaScript IDE on iOS)? What’s your experience with it?
I currently use Pythonista which is very nice and works well, but I wonder whether I should play with JSBox as well.
Is JSBox the only JavaScript IDE for iOS, or are there more? If so, which one(s) do you recommend?
Weird, I never heard of it. I tried to find reviews online and didn’t find much and the App Store reviews seem to be in Mandarin. I would also like to know more about it now.
Hey guys, I’m happy to see that JSBox is noticed by others since I made it 
The goal of JSBox is to leverage native iOS APIs using JavaScript, so I won’t say it’s a general JavaScript IDE, because it’s designed for specific scenarios.
Don’t worry about why there are many Mandarin reviews (I’m from China though), this app also has English localization and documentation: https://docs.xteko.com/#/en/
Here are two promo codes for my app, you can try it for free:
If you like it, please share it with your friends as it motivates me.
Also, there is a demo gallery which you can find many examples: https://xteko.com/gallery/en
Please feel free to reach me out via Twitter@cyanapps, I share my ideas and demos there.
For anyone else trying: unfortunately both are already taken by somebody else.
Seems like I never posted it here, but I found two more:
Scriptable which is working really well for me, for 2 use cases:
Rescript is another one, but that did not work for me.
You can send me your email, either at here or Twitter, I can add you to JSBox beta.
So after @cyanapps was so kind to give me a promo code I have been playing with JSBox myself. Wow, I’m impressed! I can’t believe that I have never seen a review of this App before… (I think the guys from MacStories.net would love this!)
In about 2 hours I was able to convert my Scriptable script for using the RTM API to JSBox and I was able to add tasks (to desired lists with tags, locations, and a comment) to RTM from JavaScript code 
(I could even remove a large part of the code since JSBox has a built-in md5 function)
I think I converted about 99%. The only thing missing is being able to run the script from Launch Center Pro, but that requires x-callback-support, which I cannot find in the documentation (I only see a URL scheme to install scripts; not to run them).
@cyanapps Does JSBox support x-callback-url? If so, how?
(Kind of surprised I could not find that; JSBox seems loaded with powerful functions)
EDIT: I discovered that I can use jsbox://run?name=rtm to run the script, but what about parameters? (I would like to pass 1 string as a parameter of the script)
When never an app opens JSBox with jsbox:// scheme, you can get all the parameters with $context.query: docs[dot]xteko[dot]com/#/en/context/method?id=contextquery (sorry, but it is said that I can’t post links)
That should work
Going to try it tonight!
I just sent you a request via Twitter messages to add me to the Beta, thanks
Got it working from Launch Center Pro after some experimenting!
Somehow this command from the documentation you provided did not work for me:
jsbox://runjs?file=RTM.js&text={{task #list #context @location // Comment}}
However, this (as suggested in the App) did:
jsbox://run?name=RTM&task={{task #list #context @location // Comment}}
