Learned regex in the 90’s from the Perl documentation, or possibly one of the oreilly perl references. That was a time where printed language references were more convenient than searching the internet. Perl still includes a shell component for accessing it’s documentation, that was invaluable in those ancient times. Perl’s regex documentation is rather fantastic. `perldoc perlre` from your terminal. Or…

I read a lot on https://www.regular-expressions.info and experimented on https://rubular.com since I was also learning Ruby at the time. https://regexr.com is another good tool that breaks down your regex and matches. One of the things I remember being difficult at the beginning was the subtle differences between implementations, like `^` meaning “beginning of line” in Ruby (and others) but meaning “beginning of…

If you are going to use RE’s, use something like https://regexr.com/ to double check that they’re doing what you want. I was suspicious of your ‘cols = re.findall(r’d+ …..’, i)’ line, and indeed it does miss some columns. You should rethink your column detection, and either not use REs or learn how to use capture groups and w. There would then be no reason to use yet another RE in your column iterator to…

First time posting here, let me know if I need to edit post to conform to any rules. My issue is that I’m trying to match regex pattern to separate out the number of cubes drawn and its color but my Matcher object seems to not be returning any matches so it’s throwing a no match found exception when I try to call digitMatcher.group(). I have tested my regex pattern on sites like regexr and it seems to pass there…

I just started learning Regex again (I did not know much before anyway), and I was playing around in regexr and I tried .[] and it does not match anything, no letter, no words, nothing even special characters.
