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. š
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 ;)

kabel42@kabel42 @mirabilos @rl_dane @amin @thedoctor No, it's absolutely not fun, first of all it breaks all scripts. They break all the shortcuts that I use all the time in interactive sessions, it's slow, and if you want to configure it, guess how you configure a command line tool it boots up a web server where you configure it... the whole thing is utterly ridiculous.
@mirabilos @rl_dane @amin @thedoctor @sotolf you probably have some browser installed anyway so why not use it. And you can rewrite all your scripts in a new, more sane, language that is not based on some legacy tech.

ksh is a type-safe, memory-safe language supporting modern paradigms like concurrency, higher-order functions and pattern matching. Its standard library even supports distributed applications and serverless architectures as well as microservices.
Not sure what should be legacy about that?
@mirabilos @nik @thedoctor @kabel42 @sotolf @amin
WAT. Sounds amazing, got an example?
Is this mksh or ksh93/2020?
@rl_dane @nik @thedoctor @kabel42 @sotolf @amin ksh2020 is completely gone. Thereās now āksh93u+mā by Martijn @mcdutchie as actively-developed version. ([Overview]ā¦ which I should update some dayā¦ oopsā¦)
This is, for now, an mksh thing; it stems from [a thread] by @navi in which she desires something like that for sh, but I chose to add it to the Korn shell-style function syntax instead because it is easy to add there without breaking anything and because it leaves the POSIX space open for future standardisation.
Itās deliberately not yet documented in the manpage or so because it can change at will and without prior notice and is, at this point, only something for people to play around with, to get a feeling for it, before it can become standardised.
(Also, I very much dislike the idea of adding it to the () of POSIX-style functions, as that would look too much like a subshell.)
general idea is:
| function (a b=foo) name { ā¦ }
ā¦ is identical enough toā¦
| function name {
| a=$1; shift
| if (( $# )); then
| b=$1; shift
| else
| b=foo
| fi
| ā¦
| }
Note that default arguments can have side effects (like a parname=[] mutable default argument in Python)ā¦
function (count=$((++selfcount_cnt))) selfcount {
echo calling me for the ${count}th time
}
ā¦ but they are shortcut-evaluated (i.e. selfcount_cnt will not be incremented if selfcount is called with an argument), like in most logic (if (foo != NULL && foo->bar > 1) would crash if it werenāt).
The [commit message] has some more information, and of course you can read the diffs linked (user=pass public as usualā¦ fscking LLM scrapersā¦) for more info, check.t contains some self-tests for this.

(Also, I very much dislike the idea of adding it to the () of POSIX-style functions, as that would look too much like a subshell.)
the main point of the thing was making the posix () not useless though ~w~
subshells arenāt allowed after a word like that in any context i can think of so imo someone would need to really go out of their way to make the syntax look confusing (most often subshells only pop up at the start of a command, or after a pipe, neither of which match function declarations much)
foo(nya mew=beep) {
echo $nya $mew
}
selfcount(count=$((++selfcount_cnt))) {
echo calling me for the ${count}th time
}
iām not a fan of the side effect thing much, but itās something i think we should have anyway due to specifying the default value the same as any normal assignment, something like mew=${2-beep}, so count=${1-$((++selfcount_cnt))}
@sotolf @thedoctor @kabel42 @mcdutchie @navi @amin @rl_dane @nik yes, thatās sort of how it works, except it actually inspects argc I think.
Hmmmm, use of $n (where n is number) in default args could beā¦ "interesting". But, I think, possible.
@navi @sotolf @amin @rl_dane @kabel42 @mcdutchie @nik @thedoctor yes, it inspects argc, and it shifts after each, so $1 is always the one in question, though I donāt think you can do anythingn useful with it.
There also is no provision for namerefs yet (and thatās beyond POSIX and very shell-specific anyway). Might be interesting, perhaps with a prefix before the variable name.
