scripting_course VS RegExr

I'm still on Vim 8.1 (Ubuntu 20). Most of my settings are available here: https://github.com/learnbyexample/scripting_course/blob/master/.vimrc

Here's mine: https://github.com/learnbyexample/scripting_course/blob/master/.vimrc

I wrote ebooks on CLI one-liners based on grep/sed/awk/perl/ruby/coreutils/etc. These are free to read online: https://github.com/learnbyexample/scripting_course#ebooks

Plenty of examples and exercises.

There are huge lists on freely available books on programming topics here:

All my book are free to read online and markdown source are available on GitHub: https://github.com/learnbyexample/scripting_course#ebooks

I did have an option couple of years back, but there were hardly any buyers. So I closed that store instead of spending time in keeping them updated.

Also, you could print to pdf using the markdown source from my GitHub repos or use tools like pandoc to convert markdown to pdf/epub.

Personally, I use gvim for all my text editing needs and use a normal terminal (i.e. no tmux, i3, etc). There's not much to share, unless you are interested in my vimrc, aliases, etc: https://github.com/learnbyexample/scripting_course

Thanks, do you mean web versions of my books? I made those using mdBook to convert markdown to html (plus js for things like search features).

https://github.com/learnbyexample/scripting_course#ebooks - I have several books on regex with plenty of examples/exercises (free to read online)

I have separate books for Python/Ruby/JS regexp. My books on grep/sed/awk include detailed chapters on regexp. You can read them for free online, see https://github.com/learnbyexample/scripting_course#ebooks for links. I use lots of examples to present a concept and there are plenty of exercises to test your knowledge as well.

I have a few resources collected here: https://github.com/learnbyexample/scripting_course/blob/master/Linux_curated_resources.md#shell-scripting

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:
