As a ruby developer, I was happy to find that VS Code / TextMate grammar files use the same regular expression engine called Oniguruma as ruby itself. Thus, I could be sure that when trying my regular expressions in my favorite online regex tool, rubular.com, there would be no inconsistencies due to the engine inner workings. - Source: dev.to / 8 months ago

In my testing on a couple of regex testers (https://rubular.com/ & https://regex101.com/) this seems to select the postcode correctly each time. Source: about 1 year ago

To add on to this from a regex perspective - I find regex to be invaluable in my workflows. Once you learn the basics I always test and debug my strings using https://rubular.com because it has string hints at the bottom that are readily available. Source: over 1 year ago

Mostly trial and error using pythex.org for python, regextester.com for c/c++, or rubular.com if you're coding in ruby for some reason. Source: over 1 year ago

One thing I've found very very useful when I just want to send a short text or a link from PC to phone is to use a QR code generator. I've used this so often that I've installed a firefox plugin to generate QR codes offline: https://github.com/rugk/offline-qr-code. Source: over 2 years ago

On my Linux-/Windows-PC I use firefoxplugin QR & Barcode Generator. The QR-Code-Window shows the current browser URL as QR-Code but you can type in any text that immediately converted to QR-Code. Source: over 2 years ago

This project is inspired by the offline-qr-code addon for firefox. Learning flutter was an extremely rewarding experience and I used this learning experience to build something for the community. - Source: dev.to / over 2 years ago
