File this under #shell #functions I should have written years ago:
function grepc {
#Do a grep -c, but skipping files with no results
grep -c "$@" |grep -v ':0$'
}
Amin, minor deity of the legume realmOh, didn't know about -c. I usually just pipe to wc -l I guess.
-c, -l, -h, -H, and -q are my favorite #grep flags. :D
Huh, that almost became a [Marcel Duchamp] reference. 😅
I just use -v and -E

Face it... I'm an unpopular-opinion neckbeard level boss. XD

@thedoctor @rl_dane @amin @mirabilos At least bash and zsh is comparable to grep ripgrep, as zsh is just a strictly better bash ;)
@sotolf @thedoctor @rl_dane @mirabilos
Mm, not really though? ripgrep is meant for bulk grepping of files
@amin @thedoctor @rl_dane @mirabilos I think I had it installed, I just never remembered to use it :p
@sotolf @thedoctor @rl_dane @mirabilos
I mostly just use it to run rg TODO and see all the spots in a codebase I marked as still needing work.
@amin @sotolf @thedoctor @mirabilos
Why is ripgrep better than just grep -R?
kabel42@rl_dane @amin @sotolf @thedoctor @mirabilos it's somehow a lot faster if you want to grep a few GiB of code, like 15 minutes to 30 seconds
@kabel42 @amin @sotolf @thedoctor @mirabilos
Interesting! I wonder what kind of algorithmic optimizations (as opposed to compiler optimizations) they're using to do that, and if regular (GNU/BSD) grep could do the same.
Because I'll wear clown shoes and a tutu before changing to a "rewrite the world in rust!" utility 😂
@rl_dane @amin @sotolf @thedoctor @mirabilos From what little i have read, some assumptions about what you are greping and different defaults. Doing the same in existing grep would probably break compatibility.
@kabel42 @rl_dane @amin @thedoctor @mirabilos Ah, so it's basically cheating, I mean, it does work, and I do it often when I create small tools, with the excuse that "It wasn't meant for that"
@sotolf @rl_dane @amin @thedoctor @mirabilos Is it cheating, if it is the second sentence in you README.md?
"ripgrep will respect gitignore rules and automatically skip hidden files/directories and binary files. (To disable all automatic filtering by default, use rg -uuu.)"
or, you didn't want to grep in .git anyway you are just too lazy to look up the flag to skip that

@kabel42 @rl_dane @amin @thedoctor @mirabilos All optimisation are just different ways of cheating ;)
@sotolf @rl_dane @amin @thedoctor @mirabilos doesn't cheating imply that you are dishonest about it?
@kabel42 @rl_dane @amin @thedoctor @mirabilos I don't know, it might be just that my mother-tongue's word for it "jukse" also has a connotation of taking the easy way out or a shortcut instead of doing the whole thing. And I transferred that over to english.
@sotolf @rl_dane @amin @thedoctor @mirabilos could be the same for German, where you have the choice of "Schummeln" and "Betrügen" :)
@kabel42 @rl_dane @amin @thedoctor @mirabilos Yeah, cheating as in Schummeln, not as in Betrügen.
I also saw now when looking the word up that it comes from german "juxen" which is "playing around, having fun" which is kind of a fun way that the word has been wandering :)
mirabilos@sotolf @rl_dane @kabel42 @thedoctor @amin cheating can be Schummeln but I think it is usually somewhat more down the scale towards Betrügen, unless explicit in e.g. game

If using assumptions for optimization is cheating, is using Newtonian physics cheating?

@kabel42 @mirabilos @sotolf @thedoctor @amin
If you rely on relativistic/Einsteinian accuracy, yes? ;)
#KSP cheats by not computing gravity between the various planets and moons. They're all on (invisible) rails. Only ships, crew, and asteroids are affected by actual gravity.
@rl_dane @mirabilos @sotolf @thedoctor @amin but your assumption when using Newtonian physics would be, that the error from doing so is irrelevant.
@kabel42 @rl_dane @mirabilos @thedoctor @amin Yeah, but you're doing less work, so you're basically cheating ;)
@sotolf @kabel42 @mirabilos @thedoctor @amin
Sometimes the cheats are a valid way to make a system more efficient ;)
