scriptular VS RegExr

I love Rubular and use it often. The "Regex Quick Reference" block is so incredibly useful too when you don't completely remember that one thing.

However it is closed source, and it sends your info to the server for processing. This is of course not (likely) nefarious, but it does give me a little pause, and means that you should never use it if the data you are putting into it is sensitive!. For example, don't test your API key parsing regex on it with real/active keys! Also for corporate dev you are (probably) violating company policy by using it.

Rubulex[1] is a neat open source clone that I use a lot. The only downside is I have to start it locally. One of these days I'll stand up a permanent instance, though I don't want to do that without auditing the code and I simply haven't had time to do that. If anyone has done so I'd love to hear about it. Scriptular[2] is an open source clone that uses javascript:

Side note: If anyone knows of or wants to build an Elixir regex tool in Phoenix/LiveView, I'd be willing to collaborate a bit and willing to host/maintain (and I'll pay for the VM/domain). I've already got some Phoenix apps running in prod so if you get it to work with `mix phx.server` I can take it from there (I know that operationalizing and devops isn't what usually interests most people). A non LiveView version would be cool too, but it seems like such a cool project to build with LiveView to be super responsive and show off what you can do (and also learn Elixir/Phoenix/LiveView with a simple app). Would be really neat to release an elixir-desktop version too! My email is in my profile if you are interested.

When thinking about how I might compare an arrangement to the contiguous group of damaged springs, I used regexr.com to experiment with very specific regexs that used the numbers.

There are plenty of online regex tools to test and experiment with regex patterns. Some popular ones include RegExr, RegEx101, and RegexPlanet.

Using regexr.com it at least appears to work as expected.

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 extract the numbers which you've already detected.

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 but it's not working for some reason here. I use the same type of regex on day one and it work there so I'm not sure where my regex pattern is failing here. I'm talking about specifically in my isGameValid() method where I create a matcher base on a pattern I made above. Through debugging I know that I separated the string color pairing correctly and that my Matcher object has the correct regex pattern, it's just not matching for some reason. Any help would be appreciated. Code below:

Regexr has been an invaluable tool as a beginner.

RegExr simplifies working with regular expressions. This online tool provides a visual interface for building and testing regex patterns in real-time, making regex less intimidating.

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.

I pulled this into regexr.com and it yielded the same results except it removed :41:
