| Nemokosch | so yeah, yesterday I managed to get one generated part of the highlighter config right | 09:45 | |
| there are five parts | |||
| is there anyone who comprehends Coffeescript strings? I came across something that looks like a Python docstring (triple apostrophe) and it seems to have comments in it, like wtf | 09:46 | ||
| exp | Nemokosch: can you show an example? I'm not aware of anything like that, but boy I haven't heard Coffeescript in a while! | 09:49 | |
| tellable6 | exp, I'll pass your message to Nemokosch | ||
| Nemokosch | okay, so they are apparently called "block strings" | 09:52 | |
| moment | |||
| exp | no need, that's enough for googling, gracias :) | 09:53 | |
| Nemokosch | github.com/Raku/atom-language-perl....raku#L288 | 09:55 | |
| there are similar things in the output as well | 09:56 | ||
| github.com/Raku/atom-language-perl....cson#L813 | |||
| the way I understand it, these strings keep the linebreaks, they are much like heredoc strings | 09:57 | ||
| however, I cannot comprehend how they can contain comments, and whether that's a language feature of Coffescript or some stupid custom hack in Atom or that Ruby regex processor | 09:58 | ||
| it seems to me that it's NOT Coffeescript that is weird about that comment | 10:02 | ||
| github.com/Alhadis/Regex-Comments#...e-comments goddamnit | 10:04 | ||
| this is indeed an Atom hack | |||
| hm, not Atom but PCRE mode of this regex engine | 10:06 | ||
| anyway, I guess I might as well leave these comments there, and see how it works out | 10:08 | ||

| Anton Antonov | I have a project in which one of the possible solutions is to construct a grammar from a list of regexes. Should I use RakuAST or the approach given here : perl6advent.wordpress.com/tag/bnf/ ? | 13:59 | |
| I assume the non-RakuAST is going to always work. Meaning, after RakuAST is finished and "main stream" the ^add_method and EVAL implementation is still going to work. Is this correct? | 14:01 | ||
| I more recent/updated work corresponding to the advent link above is this Raku module repository: github.com/tadzik/Grammar-BNF . | 14:10 | ||

| lizmat | Anton Antonov the past week I got regex / rule / token declarations to work in a useful way | 14:27 | |
| rf | Morning folks | 14:28 | |
| lizmat | I haven't written any tests for creating grammars yet, but that *should* be trivial | ||
| m: say Q|grammar A { token B { b } }|.AST.statements.head.expression # to give you an idea how that would look | 14:29 | ||

| volare | question: can i install rakudo perl using apt-get in debian? | 18:51 | |
| tonyo | m: my Buf[uint8] $x .=new; dd $x; | 18:58 | |
| camelia | Buf[uint8 $x = Buf[uint8].new() | ||
| volare | is perl6 backward compatible with perl5? | 19:02 | |
| lucs | volare: I believe it is recommended to install rakudo with rakubrew (see rakubrew.org). | 19:07 | |
| And no, Raku is similar to Perl in many ways, but it is a different language. | 19:08 | ||
| (perl6 is now called Raku) | |||

| volare | i am converting a simple perl 5 program and the for loop doesn't work | 19:24 | |
| lucs | Oh, that indeed works, but I've seen people | ||
| recommend rakubrew | |||
| The 'for' syntax may be different in Raku. | 19:25 | ||

| Implementing the Raku(tm) programming language v6.d. | |||
| lucs | Yikes, kind of old. | ||
| volare | Built on MoarVM version 2020.12. | ||
| how do you say a text and variable on the same line? | 19:39 | ||
| lucs | rakubrew can get you 2023.02. | ||
| volare: Not sure what you mean... | |||
| Maybe this?: say "Value is $the-val" | 19:40 | ||
| volare | say "\nYou thought of number: "; | ||
| say ($count-6); | |||
| evalable6 | You thought of number: |
||
| volare | i want to say both lines on one line | ||
| lucs | m: $num = 42; say "You thought of number ", $num; | 19:41 | |
| camelia | ===SORRY!=== Error while compiling <tmp> Variable '$num' is not declared. Did you mean any of these: 'Num', 'num'? at <tmp>:1 ------> <BOL>⏏$num = 42; say "You thought of number ", |
||
| lucs | m: my $num = 42; say "You thought of number ", $num; | 19:42 | |
| camelia | You thought of number 42 | ||
| lucs | volare: I suggest you join the raku-beginner channel instead of this one. | 19:43 | |
| volare | it worked thank you | ||
| lucs | You're welcome, even more welcome in raku-beginner :-) | 19:44 | |
| volare | magical.ddns.net/software/listings...ads/perl5/ | 19:45 | |

| volare | lucs: how do i join the developer community? | 19:48 | |
| lucs | Not sure, someone else can answer. | 19:49 | |
| volare | thank you lucs | 19:53 | |
| lucs | Sure thing. | ||

| rf | I didn't realise how easily you can express quicksort with Raku lol | 20:10 | |
| rosettacode.org/wiki/Sorting_algor...ksort#Raku | |||
| volare | lucs: you should watch the one with penolope cruz | 20:14 | |
| lucs | I just watched the original, Domenico Modugno, on Ed Sullivan. | 20:15 | |
| The song was a big hit when I was a kid (yeah, I'm pretty old.) | 20:16 | ||
| I'll look at the one with MsCruz. | |||

| Nemokosch | I don't like that quicksort solution, to be honest. It tries to be very generic but kinda ruins it by using flat | 20:20 | |
| it would be better to make slips | |||
