Darnit, I was going to ask him something about his code. :(

I liked Vim. RIP, Bram.

Anyone have any experience with NeoVim?

Yes, I realize I can continue using Vim even though Bram is dead, but eventually I would want something that continues to be maintained.

And, blasphemous as this may sound, I'm hoping that NeoVim uses PCRE.
I would rather switch over all my vim script to PCRE. I have to use PCRE anyway so might as well use just the one standard.

Searching #PCRE you came up as the first result.

#regex #question

I was going through some HTML markup/ content where my <h1>,<hx> tags have no anchors/ ID's. pain in the butt to do that manually if i want anchors, It occurred to me: why don't I just process the markup and use the &#x003C;h1&#x003e; (..contents ...) &#x003C;/h1&#x003e;
but the (...contents...) atom needs filtering. E.g. "this just in", maybe I want "this_just_in"

That's not really possible w/ #PCRE is it?

Maybe this is something #sed can do? Im not super fmlr w/ all gnutils

(Note that doesn’t work with software using the #PCRE Perl “Compatible” #RegularExpression library because its #Unicode support is worse: https://www.pcre.org/current/doc/html/pcre2unicode.html#:~:text=Only%20the%20short%20names%20for%20properties%20are%20supported)

@barubary @Edent Or #PCRE, the Perl Compatible* Regular Expression engine, Which is used by #PHP and #Rlang as well as the #Apache and #nginx HTTP servers, #nmap, #Postfix, and #Exim (for which it was originally written).

You can even make your #Perl compatible with PCRE instead of other Perl, but you should have a good reason (performance mostly): https://metacpan.org/pod/re::engine::PCRE2

* PCRE2’s own documentation highlights nineteen separate significant differences: https://www.pcre.org/current/doc/html/pcre2compat.html

@Codely @drupler It helps to build your complicated #RegularExpressions in pieces and store them in separate variables. You can then test them in isolation and not be confused when you concatenate them together for your actual matching.

Both #PHP and #JavaScript also support named capture groups if you’re doing replacements. They’re a lot more readable.

Also, PHP’s #PCRE-based engine has a PCRE_EXTENDED flag that lets you add whitespace, newlines, and comments.

#regexes #regexps

Ah yes my old nemesis regular expressions, just typing that made my blood pressure go up.

It's a simple to explain request, that has proved elusive to actually match (I have never pretended to be a programmer).

I guess automating Palo Alto Networks EDL creation is going to take a while /sigh

#pcre #regexp

@thfr

Good to know I don't have to fetch GNU ls ^___^

But honestly, not missing it. :D

Is colorls developed by one of the #OpenBSD devs, or is it imported from #FreeBSD?

The only thing I sometimes miss is the #PCRE. Even vim seems to be missing it, for some reason.
Oh, and emoji. Emojis work great in Chromium, but almost nowhere else.

I just completed "Tuning Trouble" - Day 6 - Advent of Code 2022 #AdventOfCode in #regex (#pcre #grep) https://adventofcode.com/2022/day/6

https://github.com/lucaswiman/advent-of-code/blob/main/2022/0006/solve.regex

Uses negative lookahead assertions and backreferences to force uniqueness. Then feed it to `grep - Pbo` (P=Perl regexes, b=byte offset, o=only match) to get the position.

@mjgardner @benjaminhollon @marcxjo

I wonder where #PCRE came from, if not from Perl, then?

@benjaminhollon @TheTuzu

I use bc, but python is good, too.

I'm tempted to use perl as grep on #OpenBSD for access to yummy #PCRE ^__^

@benjaminhollon @marcxjo

Regex is really quite decent, but definitely an acquired taste.

I particularly like #regex in #perl, because #PCRE (Perl-Compatible Regular Expressions) are super powerful, mostly instead of needing to use large character classes like [[:alnum:]], [[:space:]] and [0-9], you can just write \w, \s, and \d, respectively. There's also the massively powerful \b, which represents a word border.

Having some trouble with cmake-bootstrap on #powerpc on #guix on core-updates-frozen. 3.16.5 worked fine but 3.20.1 and 3.21.3 both hang forever while building. I might need to try adding back a 3.16 version for powerpc and using that to build cmake-minimal.
After all of that I still need to look at #pcre and pcre2 and the failed jit tests on powerpc.
