regex-generator VS regexgen

Whilst Regular Expressions are undeniably powerful --- virtually NOBODY knows how to set up Regular Expressions!  There are a number of tools that help you build / test regular expressions, such as https://regex-generator.olafneumann.org/  or https://retool.com/utilities/regex-generator (no responsibilities accepted for the use of any  of these tools!)

Ho did you arrive at the regex? I usually use a website to , such as https://regex101.com/, https://regexr.com/, https://regex-generator.olafneumann.org/ in combination of each other, as some explain better than the other.

Is there a regex generator for Reddit's Automod or Python? I've already tried Googling "regex generator python" but I only came up with https://regex-generator.olafneumann.org/, https://pythex.org/, https://regex101.com/, and a whole bunch of build/testers. Olaf Neumann's generator seemed the most promising, but I couldn't get it to work because I didn't know how to separate each phrase, i.e. "you're dumb," "your dumb," "youre dumb," and "you are dumb." I was able to make sense of https://www.javainuse.com/rexgenerator but it's only for java.

Here's some more websites that might help if you're interested: https://regexr.com/ - Lets you test the regex https://regex-generator.olafneumann.org/ - Can help you generate regex https://en.wikipedia.org/wiki/Regular_expression#Basic_concepts - Basic syntax

https://regex-generator.olafneumann.org/ (type in any text and it will suggest a matching regex)

I really like this tool to generate regex. It may not generate exactly what you need, but it'll get you on the right track. Often times, it does what I need.

Nah, just use a RegEx generator and then the REGEX(text, regex_text) in a validation rule and you are done.

This is a special case of the general problem of program synthesis[1][2][3][4], where the search space of possible programs are all regex strings and the seed driving the synthesis is Input-Output examples.

There's research [5][6] as well as practical tools [7][8][9].
