| thowe | what does "+%" do? Specifically I am looking at a grammar that was made for parsing ip addresses and this is part of some of the regexes. That's here: rosettacode.org/wiki/Parse_an_IP_Address#Raku | 15:12 | |
| that symbol isn't in the docs | 15:13 | ||
| that said, I also can't find "hexdigit" | 15:15 | ||
| I mean, I'm guessing it is a character class, but it isn't constructed here, so is it a built-in character class? | 15:21 | ||
| Ah, is it maybe old syntax??? There is a character class <xdigit> that should match a hexdigit. Is it deprecated code maybe? | 15:23 | ||
| hm <xdigit> and <hexdigit> both work interchangeably when I run the code... Must be some leftover syntax(?) | 15:34 | ||
| still wondering what +% is | 15:47 | ||
| or maybe that's not an operator and they have specified a modified quantifier in a funny way.... That makes sense I think | 15:51 | ||
| I was wrong, hexdigit and xdigit are not equiv now I'm confused again | 15:55 | ||
| I asked in the other channel and apparently it's a unicode class, and case and underscores are ignored, so Hex_Digit can be hexdigit. sites.google.com/site/icuprojectus...properties | 16:28 | ||
| newer stuff is harder to find but is here: unicode-org.github.io/icu/userguid...rties.html | 16:30 | ||
| gfldex | thowe: hexdigit is defined in the Raku grammar. | 17:47 | |

| stevied | i have a command the prompts a user for input. I want to get at the output of the program. So I have this: | 18:36 | |
| ``` | |||
| my $proc = Proc::Async.new('bin/docexec'); | |||
| $proc.stdout.tap(->$v { say $v; say 'bye'; }); | |||
| $proc.start; | |||
| react { | |||
| whenever Promise.in(1) { | |||
| $proc.kill; # sends SIGHUP, change appropriately | |||
| } | |||
| } | |||
| ``` | |||
| however, I'm not getting anything back in `$v` | |||
| ah, dammit, was getting back something but first line was blank. | 19:19 | ||
| how do I get back all the lines? | 19:20 | ||
| ok, there was some line buffering going on. using "unbuffer" utility did the trick. see stackoverflow.com/a/63513815/1641112 | 20:26 | ||
| thowe | gfldex: where do you see hexdigits defined? | 20:54 | |
| stevied: I'm willing to play with it a bit, but I think you need a pastbin or gist or something so I can get your real code. | 21:44 | ||
