​Hello morning！

Kathy H
​Yes， can you please talk about regular expression in elisp ?

Kathy H
​hahahaha, cool...I always wondered how people did that and especially WHY

Kathy H
​I am a phd doing machine learning research, almost do minimum programming compared with other coder (coz normally what make thing working is just a few line of mathmatical functions).

Kathy H
​But I am thinking doing something more practical for fun, natural language analysis with web scrapping etc, regular expression is under-rated in all academic study..

Kathy H
​yes, statistics

Kathy H
​R, unfortinately 😛

Kathy H
​yes, elisp regex is a bit different from others, so many escape backward slashes, got me confused haha

Derek Ackley
​Good morning Xah!

Kathy H
​that makes sense, thank you!

Kathy H
​exactly, Normally I look at regex, we can understand what it matches at glance...but in emacs. I got lost pretty quickly in counting slashes

GrinDeg
​Hi!

Kathy H
​but emacers have to know that to write customerized configurations...

Luis Henriquez-Perez
​@Kathy check out the rx macro

Luis Henriquez-Perez
​it's built in emacs.

Kathy H
​@Luis Henriquez-Perez cool, will do, thanks

Kathy H
​I agree. No intermedia if possible. I do want to hear your experience about which to add backward slashes etc

Kathy H
​coooool

​Hello Xah, it's been a while

GrinDeg
​why did it delete spaces?

Kathy H
​yes, very helpful, thank you.

Kathy H
​I didn't know there was a query-replace-regexp. Absolutely good enough workaround to me. 👍

GrinDeg
​oh ok

GrinDeg
​Does common lisp have any practical use today? I'm reading a book about it right now, very interesting, because i don't know anything about lisps. I've heard that clojure is very similar to c. lisp

​Hello.

Kathy H
​Yeah. I think listing matching lines with regex is important in daily work.

Kathy H
​There was a question on Emacs London meetup – how to manage/visualize many text/org file with tree structure, especially those text/org files that are not belonged to any tree branches.

Kathy H
​I think searching with regex can solve the management problems. Visualization is difficult if you have thousand text files. I give up on visualization structure already.

GrinDeg
​Yeah. I'm learning it just for fun, not for a job. so i should probably switch to scheme. GNU Guile maybe

Kathy H
​yes

Kathy H
​cool! Thank, I will let him know. He raised this question coz he started using emacs with outline mode in 80s. (back in 1980s there was no org-mode yet)

​Intro to Mindmap, Gantt Chart, Graphviz http://ergoemacs.org/misc/mindmap_gan...

Kathy H
​yes, that's what he wants to know I think

GrinDeg
​Oh ok will do racket then

Kathy H
​thank you! 😁 bye
