Od1n hello 13:26
jberkel hi, i'm trying to write a simple regex but it's already failing. I want to match a single hash (#) sign: my regex hash { \# }; => Malformed regex 13:28
does hash need to be escaped in some other way? 13:29
Altreus quote it 13:32
Juerd It works with '#' but shouldn't \# work too? 13:33
Altreus that's one for the grown ups 13:34
I just know non-alnum strings need quoting
jberkel docs.raku.org/language/regexes mentions: / \# /; # matches the hash metacharacter literally 13:35
so i assumed that's the way to do it
it looks like the # is interpreted as end of line comment, leaving a single \ 13:37
13:43 dakkar left
Altreus ah, regex foo { ... } doesn't trigger the same parsing rules as / ... / then I guess 13:46
Shaeto what does meat *@ and *% in parameters definition ? 13:50
tyil[m] Shaeto: docs.raku.org/type/Signature#index...y_argument 13:52
jberkel ok, it works with quoting, so i'm already a bit further. thanks 13:54

Xliff Good morning. 18:04
How hard would this be to implement?
Heredoc quoting construct is q:to/END/ right? 18:05
18:05 reportable6 joined
Xliff WVCards, markup their ilk are becoming more popular and they include their own ending delimiter? 18:05
So why not a heredoc that has the ending inclusive so one can do.... 18:06
q:TO/END:VCARD/?
Would this be better served on problem-solving?
codesections I kind of like that. Proposed syntax: q:thru/VCARD/ 18:07
but yeah, I think that'd probably need a problem-solving issue, since it'd be a new language feature 18:08
holly maybe use delimiter problem solving
e.g. theorem prover
codesections Would it only work for a delimiter that is the only thing on its line? Or any line-terminal delimiter? 18:10
Xliff codesections: Only thing on its line.
I will move to problem-solving. Thanks!

guifa Xliff++ that sounds like a pretty nice proposal 19:17
I don't think it would be too hard, it's probably just setting a boolean during parsing and then adjusting the cut off point for the string somewhere along the way 19:18
(although it's crossing language boundaries, so that may complicate it a bit but not too badly)
Xliff guifa: I don't think it will be too hard to implement. I am just seeking thoughts on the matter, so if you can comment on the issue, I'd appreciate it. 19:21
guifa Xliff: will do. your stray space actually causd jnthn to make a really good point (although he didn't expound on it) 19:25
The location of END in a normal q:to/END/ lets the parser know how many spaces on each line to strip out 19:26
since it's on its own line, that doesn't really cause any issues at all. But for, e.g., an XML end tag that may be on the same line as one or more other tags, it's not clear how to apply the indent-stripping functionality 19:27
lizmat guifa: the end string needs to be the only thing apart from whitespace, no> 19:28
?
guifa in a traditional heredoc yeah. 19:29
codesections Yeah, I asked about that ^^^ and Xliff confirmed that would still be true in this proposal
guifa err whoa, I totally missed that, apologies
codesections But yeah, absent that it'd get ... tricky 19:30
(That'd be nice in many use cases, but much harder to implement)
guifa I guess you could always allow for an extra modifier, but that does complicate it more. Like q:thru:4indent/</xml>/; 19:31
(and so I'd probably not recommend it ha) 19:32

holly YARH :-) 19:50
colomon o/
Having a really weird show-stopper problem in my Raku script. I have a class which "has %.files". When I try to look at %.files, Raku hangs. Hoping this rings a bell for someone... 19:56
gfldex codesections: I'm still waiting for "QA driven development". 19:57
lizmat colomon: how do you "look" ?
colomon lizmat -- pretty much any way I've tried fails. For sure dd %.files 19:58
lizmat could you do a dd %!files ?
colomon oh! That does work. 19:59
Tried it earlier, but still hung because I had another %.files later, and I didn't notice it ran further before hanging
Xliff codesections: LOL! That's a bug I just found in my code. Hah! 20:00
lizmat colomon: also realize that %.files is just short for self.files could that explain something ?
colomon ARGH 20:01
that's it -- idiot me also defined a files method, which of course calls itself
okay, I can fix this no problem. Thank you for helping me sort things out. 20:02
holly so %!, %. problem
Xliff Class Attribute doesn't have a .private ? Can I ask why? 20:03
So instead I have to do $attr.name.starts-with('$!') which seems LTA 20:04
colomon lizmat++
Xliff Actually, $attr.name.substr(1, 1) 20:05
Check that against '!'
lizmat attributes always have the private name, no?
20:06 patrickb left
Xliff lizmat: With '!' as a part of their sigil? 20:06
lizmat: Yes, but as part of the public API, I would rather have a method than a check on attribute name.
lizmat m: class A { has $.a }; dd A.^attributes.head.name
evalable6 "\$!a"
20:07 tejr joined
Xliff lizmat: Would a PR adding a .is-private be worthwhile? 20:07
japhb Xliff: You're wanting to know if there was an auto-generated accessor created for the attribute?
Xliff japhb: Sure. But also if its considered private! 20:08
:)
Consider: "$attr.name.substr(1, 1) eq '!';" vs "$attr.is-private" in code.
I would prefer the latter.
japhb But that first one is broken is what lizmat++ I think was trying to say.
Xliff Yeah. It was. 20:09
Moved on from that.
japhb All attributes are created with a ! twigil ... it's just a question of whether an accessor was generated.
Xliff japhb: OK. How would one check for an accessor?
20:10 tejr left
japhb But of course you can create your own accessor, so I think we have a similar problem to knowing if a sequence is infinite 20:10
lizmat m: class A { has $.a }; dd A.^attributes.head.has_accessor
evalable6 Bool::True
lizmat m: class A { has $!a }; dd A.^attributes.head.has_accessor
evalable6 Bool::False
Xliff m: class A { has $.a; has $!b }; A.^attributes.map( *.name ).sa
evalable6 (exit code 1) No such method 'sa' for invocant of type 'Seq'. Did you mean any of
these: 'isa', 'say', 'so'?
in block <unit> at /tmp/_gRyyg7081 line 1
Xliff m: class A { has $.a; has $!b }; A.^attributes.map( *.name ).gist.say
evalable6 ($!a $!b)
lizmat Xliff ^^
has_accessor is what you want
Xliff lizmat++
Thank you. 20:11
holly cool
lizmat++
lizmat m: class A { has $!a; method a() { "foo" } }; dd A.^attributes.head.has_accessor
evalable6 Bool::False
lizmat it really is the flag that indicates whether an accessor should be made automatically 20:12
Xliff m: class A { has $!a; method a { $!a } }; dd A.^attributes.head.has_accessor
evalable6 Bool::False
Xliff heh
lizmat m: class A { has $!a; method a() { "foo" } }; dd A.^attributes.head.has_accessor && !A.^find_method("a")
evalable6 Bool::False
lizmat m: class A { has $!a; method a() { "foo" } }; dd A.^find_method("a") 20:13
evalable6 Method a = method a (A: *%_) { #`(Method|94155151744592) ... }
lizmat m: class A { has $!a }; dd A.^find_method("a")
evalable6 Mu
lizmat Xliff: I guess you can do something with that to your liking ?
Xliff lizmat: No. .has_accessor is what I was looking for. Just checking for a gotcha. 20:14

codesections gfldex: wow, I'd never thought of implementing bare strings like that. I can't decide if I love it, hate it, or both! 20:32
(er, nvm actually, I read that too quickly/got over-excited – I thought you meant something more by "bare strings". Still very cool, but not quite as wild as I first thought) 20:38
guifa codesections: that said, it would be not too difficult to implement a php-esque DSL starter 20:39
imaging doing <html> and </html> as the equivalent of “ and ”
But that could also interpolate variables AND then generate a non-Str object as the result (instead of a Str, though presumably would have a .Stringy method) 20:40
codesections You mean as a slang? 20:42
guifa Yup 20:43
The only issue I've had so far with my slangs is enabling handing control back to the other (Quote / Core / Regex) languages. I *think* I can figure that out but since the project I've been doing it with will rely heavily on RakuAST, I've not looked too far into it 20:45
Xliff Hrm. Looking at Perl6::Grammar, I may have to revise my opinion on implementation. 20:47
Even knowing the rule name, I can't see where I'd add q:thru...
Doc_Holliwood is there any writing on why we use @a[*-1] instead of @a[-1] like Perl does? 20:48
$a[-1] rather 20:50

Doc_Holliwood i know
Xliff Doc_Holliwood: Better written now as @a.tail
Doc_Holliwood i just wonder what's wrong with negative indexes?
gfldex It's easy to get wrong by simply typos/thinkos. 20:52
my $index = 10; say @a[$index-1]; # and here you forget to type $index
