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 "$@" |grep -v ':0$'
}
mirabilosReally? Even if I'm supplying options like grepc -i foo *.md?
Or should I use IFS=$'\n'?
Seems you were right! I need to skim that part of the manpage again. 😋
@rl_dane yes. And absolutely no, do not touch IFS for this.
"$@" basically means “pass the argv array as-is”.
What happens if you forget the double quotes?
Interesting, that feels kinda counter-intuitive, since not quoting things usually keeps them separate, and quoting them lumps them together, like:
~ $ string="hello there"
~ $ for x in $string; do echo $x; done
hello
there
~ $ for x in "$string"; do echo $x; done
hello there
~ $

it's easier to think of $@ as an array type to me
if you quote a string, it goes as is, if you don't, it is split
if you quote an array, it goes as is, if you don't, each entry is split
this would feel a lot less "special case-y" if we had proper arrays variables other than arguments... i'm working on it...

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
Heh, I just got to run grep grep on my shell history.

thedoctorI use ripgrep if I want to, say, search a whole codebase.
...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

LISTEN, I've used grep/awk/sed for very nearly a quarter century, and I find the syntax of jq bewildering, so 😝
@rl_dane @thedoctor @sotolf @mirabilos
Most of those aren't for handling complex data types, though, just manipulating lines.
@amin @thedoctor @sotolf @mirabilos
So far, I've managed to bodge it together just well enough to do what I needed, but I really would like to get more familiar with jq.
@amin @rl_dane @thedoctor @sotolf jq is absolutely bewildering, especially the insistence on filtering (splitting the input stream is so hard and counter-intuitive), but it’s an ok tool if you have JSON. Or YAML, which I [convert (user=pass public)] to JSON anywwy.
xmlstarlet is lovely!
@mirabilos @amin @thedoctor @sotolf
Is it possible to convert JSON to XML and then use xmlstarlet? 😄
kabel42@rl_dane @mirabilos @amin @thedoctor @sotolf you can convert binary to xml if you want https://xmpp.org/extensions/xep-0239.html
@kabel42 @mirabilos @amin @thedoctor @sotolf
Sufficiently evil. XD
I remember when XML was the buzzword back in the late naughties.
@mirabilos @kabel42 @sotolf @thedoctor @amin
Well, if Google hates it, I'm probably on board by default. XD
@rl_dane @amin @thedoctor @sotolf yes, but you’ll have to find out a schema you want to use.
Of course, you could just convert…
{ "foo": ["bar", "baz"], "bar": true }
… to…
<JSONObject>
<element name="foo"><JSONArray>
<element><JSONString>bar</JSONString></element>
<element><JSONString>baz</JSONString></element>
</JSONArray></element>
<element name="bar"><JSONBoolean>true</JSONBoolean></element>
</JSONObject>
… or worse (Apple “plist”), but I suspect you’d rather have something semantically correct.
A lazy way to do this is with [iXML] (“invisible XML”, via @linguacelta of “AIn’t” fame); note you’ll most likely want the draft spec, not the release, because the latter misses a way to specify an XML alias and just uses the grammar name, which must be unique, for the XML element name (so the above mapping, which has object elements and array elements, would not be possible with the 1.0 spec).
That being said, if you do want such a systematic mapping, I could write you a little jq script to do that.
Do note that U+0000 (ouch! I wish it weren’t), U+0001‥U+0008, U+000B‥U+000C, U+000E‥U+001F, U+FFFE‥U+FFFF (ouch²!) are valid in JSON but not XML (and (X)HTML forbids further codepoints). xmlstarlet will likely refuse a document in which these occur (and no, even writing them as numeric entities like  is not permitted).
@rl_dane @mirabilos @thedoctor @sotolf
I do not feel up to subjecting my notifications to a revival of this thread right now. Bye y'all. :)
@thedoctor @rl_dane @amin @mirabilos At least bash and zsh is comparable to grep ripgrep, as zsh is just a strictly better bash ;)
@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. 
@mirabilos @rl_dane @amin @thedoctor @sotolf extra fun if you install it on a shared server in the lab and make it the default shell.
@kabel42 @mirabilos @rl_dane @amin @thedoctor On most of the servers that I manage, no I don't have a browser installed, why would I? And fish's language, sane? what you smoking bro? I want some of that as well.
@rl_dane @kabel42 @sotolf @thedoctor @amin I do have lynx, but also the feeling that that isn’t what you are thinking of when you write browser
