Hey everyone 👋 , Regular expressions are real; hate it or love it. I used to spend hours trying to craft the perfect expression for my scraping projects not realizing that I don't really know regex. This tool is a cheat sheet that also explains the commonly used expressions so that you understand it. - There is a visual representation of the regular expression (thanks to regexpr) - The application shows matching strings which you can play around - Expressions can be edited and these are instantly validated Looking forward to your feedback, Geon George :)

@geon_george Couldn't help but chuckle reading this part about "I used to spend hours trying to craft the perfect expression for my scraping projects not realizing that I don't really know regex." I'd wager you know a lot more about regex now? This is the developer's curse. We are always trying to fix the things that make our lives difficult when a lot of times it's not our expertise.

@rayliverified I would say I know a way more than I used to before I started the project. But I wouldn't still hire myself as a "regex expert". Whoever invented this thing is smart but people like me using it gave it a bad reputation

@geon_george Thank you so much for making this tool :)

Even if you don't actually hate regex this can be really useful. Especially the visual representation can help understanding what is really happening in that weird two-liner expression you wrote three years ago. Also there's several examples that can help you get started. Good idea for improvement would be some kind of drag and drop UI for making new expressions. Keep it going :)

This is a great idea. I often need to use regex and always struggle to remember the expressions, so I am definitely bookmarking this tool! Congrats on the launch!

@alelepd Thank you <3 mind telling me what kind of regex you use often?
Alejandro León
Spline
@geon_george For example to get a piece of string within a string, when there are characters before and after the string or to remove parts of strings after or before certain characters with variable length.
