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 "$@" |grep -v ':0$' }

#unix #UnixShell #ShellScripting #bash #ksh

@rl_dane

Oh, didn't know about -c. I usually just pipe to wc -l I guess.

@amin

-c, -l, -h, -H, and -q are my favorite #grep flags. :D

Huh, that almost became a [Marcel Duchamp] reference. šŸ˜…

Marcel Duchamp - Wikipedia

@rl_dane

I just use -v and -E

@amin @rl_dane you guys use flags?... :p
@amin @rl_dane @sotolf You guys still use grep instead of ripgrep. Tst

@thedoctor @amin @sotolf

...and bash instead of zsh
...and grep/awk/sed instead of jq
...and firefox instead of chrome
...and the fediverse instead of facebook

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

cc: @mirabilos

@rl_dane Those are so not comparable!

@amin @sotolf @mirabilos

@thedoctor @rl_dane @amin @mirabilos At least bash and zsh is comparable to grep ripgrep, as zsh is just a strictly better bash ;)
@rl_dane @sotolf @amin @thedoctor strictly even slower 😹
@mirabilos @rl_dane @amin @thedoctor Well, I see you have never tried fish :p
@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. 
@rl_dane @thedoctor @kabel42 @sotolf @amin the Korn Shell language is neither legacy nor insane
@kabel42 @sotolf @rl_dane @amin @thedoctor also, I hate how "legacy" and "modern" are fighting words nowadays. Best to avoid them in polite conversation.

@mirabilos @kabel42 @rl_dane @amin @thedoctor

Legacy is mostly the safe route to go anyway, tried and tested, I am the one that gets called if shit stops working, and I'd rather have something I know and makes sense, with tons of resources of administrators of the before times having struggled with them to help me figure out what is going on. Rather than modern stuff, with their ai documentation, discord "forums" and shipping their whole pc (docker) because they couldn't get their shit to work on a clean system :p

@mirabilos @rl_dane @amin @thedoctor @sotolf legacy had old bugs that are well documented and no one dares to fix, modern has, too often, not learned from past mistakes

@mirabilos @thedoctor @kabel42 @sotolf @amin

ksh got started in... 1983? That's not legacy? XD

@kabel42 @sotolf @rl_dane @thedoctor @amin not in the sense if the word that is commonly used/understood contemporarily, no
@mirabilos @sotolf @rl_dane @thedoctor @amin If you are refering to the original version, the Wikipedia definition doesn't feel that off: "In computing, a legacy system is an old method, technology, computer system, or application program, "of, relating to, or being a previous or outdated computer system",[1] yet still in use." -- https://en.wikipedia.org/wiki/Legacy_system
Legacy system - Wikipedia

@kabel42 @sotolf @rl_dane @thedoctor @amin that’s not how the word is used these days. ā€œlegacyā€ and ā€œmodernā€ are fighting words, at this time. 😾
@mirabilos @sotolf @rl_dane @thedoctor @amin matches my understanding and use of the word 🤷
Alternatively, something that used to be popular but has been replaced with something newer in many applications but remain in some use cases
@kabel42 @sotolf @rl_dane @thedoctor @amin since systemd was forced down our throat, the use of these words changed

@mirabilos @kabel42 @sotolf @thedoctor @amin

Probably because people are addicted to the breakneck pace of "progress," novelty, and chasing their tails.

Maybe I'll spin up a laptop that only runs Unix v4 in a VM to try to spin the earth a tiny bit in the other direction. šŸ˜†

(Likely not)

@rl_dane @thedoctor @kabel42 @sotolf @amin @mirabilos

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?

@rl_dane @nik @thedoctor @kabel42 @sotolf @amin btw, have you seen the latest (experimental) feature (named parameters)?

@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. There’s now ā€œksh93u+mā€ by Martijn @mcdutchie as actively-developed version. ([Overview]… which I should update some day… oops…)

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.

It’s 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 { … } … is identical enough to… | function name { | a=$1; shift | if (( $# )); then | b=$1; shift | else | b=foo | fi | … | }

Note that default arguments can have side effects (like a parname=[] mutable default argument in Python)…

function (count=$((++selfcount_cnt))) selfcount { echo calling me for the ${count}th time }

… 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 weren’t).

The [commit message] has some more information, and of course you can read the diffs linked (user=pass public as usual… fscking LLM scrapers…) 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 aren’t 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 }

i’m not a fan of the side effect thing much, but it’s 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, that’s sort of how it works, except it actually inspects argc I think.

Hmmmm, use of $n (where n is number) in default args could be… "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 don’t think you can do anythingn useful with it.

There also is no provision for namerefs yet (and that’s beyond POSIX and very shell-specific anyway). Might be interesting, perhaps with a prefix before the variable name.
