Introduction

Matsuya Do you like it? I love. Matsuya is a favorite of all such engineers, but smartphones official app and [on LINE](http://www. matsuyafoods.co.jp/line/) Did you know that coupons are being delivered?

You can use it by holding the QR code over the touch panel ticket vending machine [^ 1], but it is troublesome to start the application or LINE and display the QR code, and if the screen brightness is low, read it well. not. It is a well-known fact [^ 2] that people who spend 17 seconds or more to issue tickets at Matsuya are unavoidable, so ** display the latest QR code ** and ** screen brightness adjustment ** with one tap. I wrote a script for Pythonista for iOS that will do it with **.

Pythonista for iOS is a Python environment that runs on iOS, and even though python runs on iOS, it's dangerous, but you can also touch Objective-C objects from python, and so on. [^ 3]

[^ 1]: In the case of an old ticket vending machine, you can use it by presenting the coupon to the clerk. [^ 2]: Citation needed [^ 3]: This blog is detailed about dangerousness. Speaking of the appeal of the revolutionary manufacturing environment "Pythonista 3" that runs on iOS
