 All right, so next up my friend. All right, uh, Neil I wanted to share a supplemental cool stuff found last week one of the cool stuff founds was the app expressions Which I agree is a great tool for developing and verifying regular expressions. I have been using this website Reg X 101.com which has been free to use allows you to specify several different dialects of reg X's Including standard Python, Golang and others and provides a nice visual system for building and verifying to our reg X's nice Cool. Yeah, I never gotten a reg X's You know, they are super powerful and super efficient I I use them when I know that I need to be using them But I as I've said many times I do not speak reg X Natively, so I need stuff like this. So I love things like this. It's great. Very good Yeah, and you may be asking yourself, what is a regular expression? It's a sequence of characters that specifies a search pattern Yeah, it's a search pattern. That's right. Yeah, you can define like like, you know, a simple one would be to say, all right Find me every file that ends in dot txt, right? And so, you know, we we we tend to think of that as like star dot txt it's red it's Represented differently in a regular expression, but that sort of thing can happen but you can also say find me all the files that start with a number any number and then have you know Somewhere between zero and and any number of other characters, but have the word John in there somewhere and then end in dot txt and you can write one right I can't but you can write one regular expression that will define that search pattern And so it becomes this really powerful thing because it's super efficient You don't have to do all of these if then else statements to parse your your text and it doesn't have to just be file names It could be anything you're just putting text through it and out the other side comes the filtered list So it's a pretty cool thing and it's pretty universal in that it's available and I guess every programming language including shell scripting
