codesections samebchase-: I used the Acme-Advent-Highlighter: github.com/raku-community-modules/...ighlighter 04:47
(it worked well, though it did slightly mangle links with a ) in the URL) 04:49
Oh, and when pasting it in to WordPress, I initially missed the « ensuring you're editing in "HTML" and not "Visual" mode» step, which made everything break. But after I learned to read a bit better, it worked well :D 04:54

Geth doc: fcb449ba2f | (Moray Jones)++ (committed by Juan Julián Merelo Guervós) | doc/Language/rb-nutshell.pod6
Changes BUILD to TWEAK in code example

Code example now works using TWEAK instead of BUILD.
Changes description to mentions TWEAK instead of BUILD too.		 06:23
doc: 8041a648f4 | (Moray Jones)++ (committed by Juan Julián Merelo Guervós) | doc/Language/rb-nutshell.pod6
Changes twigil to public

There is no reason in this example to show a private attribute.
This clarifies that TWEAK can use $! to access attributes and that it's not a typo, without going into an explanation at this stage.

notandinus what's the difference between token and rule? 10:12
10:12 nige left, nige joined
moon-child rule can have whitespace around it 10:13
notandinus i dont understand, can you give an example? 10:14
oh nvm i found an example 10:16
moon-child basically a token is a single object, the equivalent of a word. This is like a number, a string, special char, &c
and a rule is a way to combine the two
notandinus :m docs.raku.org/language/grammars it was here
i see, makes sense, thanks
moon-child :)
10:17 nige left, nige joined
notandinus and can that single object have space in it? 10:17
moon-child only if you explicitly allow it 10:18

notandinus hi
oh i see, thanks tellable6
tellable6 notandinus, I'm happy to help!
notandinus going by this: docs.raku.org/language/grammars#Rules 10:32
isn't it the opposite of what raku says?
token is not ignoring the space, rule is ignoring it right?
for token to match the second case we'll have to specify the space, how is it ignoring it then? 10:33

ben_m Is there a way to feed/chain into a reduction operator? i.e. instead of `[+] (1..10).map(10 + *)` something like `(1..10).map(10 + *) ==> [+] # does not work` 15:43
I know that .reduce exists, but sometimes that can be less elegant (`.reduce(* * *)` vs `[*]`)

RaycatWhoDat Hey. Had a question. I only have a cursory knowledge of grammars and how they work in Raku. If I wanted to make something that resembled a compiler, how would I go about that using Raku? I feel like doing something like that is definitely possible but I'm wondering if I'm just being naive... 21:11
tyil RaycatWhoDat: andrewshitov.com/2018/11/06/creati...th-perl-6/ 21:12
RaycatWhoDat I know compilers are hard work but I was thinking of just starting with a simple interpreter and starting to build on it from ther-
oh
how convenient
codesections :D much of the main Raku compiler uses grammars, too 21:13
21:13 seanrobert left
RaycatWhoDat mmhmm. I would just wonder how adding features would work with it. Like, if I wanted to add something as complex as pattern matching, does Raku make my life easier or harder? 21:14
codesections RaycatWhoDat: also, for examples of interpreters, seeexamples.p6c.dev/categories/interpreters.html 21:15
RaycatWhoDat Although, this whole effort is stemming from someone saying that Raku didn't have anything to offer in terms of compiler/interpreter design? 21:16
.*
codesections (though some of those are a bit old)
I'm not sure I know what they meant by that 21:17
RaycatWhoDat Same. They probably did the same thing people like doing: take a cursory glance at something with no real intention of learning and just wave it away 21:18
They're building a language that looks Haskell-esque with Elm, I think 21:19

JustThisGuy Hi all! I have a couple of questions. I'm trying to do something like this: 23:49
say '"in quotes"' ~~ / '"' <-[ " ]> * '"'/;
evalable6 ｢"in quotes"｣
JustThisGuy From docs.raku.org/language/regexes "Enumerated character classes and ranges"
But, I want more that one type of quote. Something like this, but this doesn't work: 23:50
token attribute_value { <quote> ([$<-quote>]) $<quote> };
token quote { <["']> };
I found this discussion which is also similar, but it didn't seem to go anywhere: github.com/Raku/problem-solving/issues/97. 23:51
Any answers or alternatives are appreciated!
