  • Does this RegEx have mistakes in it? | 2021-10-20
    Aha okay, thanks. I looked at and apparently dots, dollars signs and question marks don't have to be escaped when between square brackets. That only leaves me with two questions: is this the case for all interpreters? And which is best practice, to escape or not to escape between square brackets? | 2021-10-20

    Let's give an example: say I'm working on and I can compute a regex in 1ms with code focused on maintainability or 0.5ms with intricate, carefully optimized code. What, in this example, is 'wrong' or 'trivial' about preferring the first option, if you concluded that it is better for your business long-term?

    Personally, I like RegExr. Just make sure to set the RegEx engine to PCRE (instead of JavaScript) to get something close to Python's native RegEx engine.

  • My Coding Bootcamp Journey - 1 week to go 😅 | 2021-10-09
    It actually turned out kinda OK. Like all programming languages (I know it's not a language) there is rules, structure and logic and the tutorial and tools like regexr demystified it a lot and I now feel ready to embrace it and learn more. It certainly looks to be very useful in some circumstances.
  • Why is this matching? - PCRE Regex | 2021-10-07
    Tested on: with the PCRE engine. This error is also occurring in my code as well.
