| i'm getting a when using mi6 that reports Tap is using deprecated code | 14:00 | ||

| any idea what i should do, if anything? thnx | 14:02 | ||

| Slaytanical | I'm going to be giving all the documentation i can find a good read tonight, but I'm going to attempt to setup "rakudo on a (usb) stick" where everything related to it (including zef stuff) stays on the usb stick. Any pointers? or has someone done this in the past and can point me to the instructions? Ty in advance (: | 16:02 | |

| tellable6 | 2021-09-15T15:12:34Z #raku-dev <lizmat> melezhik you might find this interesting: raku.land/zef:lizmat/Rakudo::Options | ||
| melezhik | lizmat++ | 16:40 | |
| this is not good - github.com/melezhik/topsdevops/blo....raku#L121 as it redirect user to "/" with POST method | 16:41 | ||

| Altreus | I don't think redirect specifies a method at all | 17:12 | |
| you can use redirect :see-other to give it a 303 | |||
| oh they went | 17:13 | ||
| I think the answer is to use created, not redirect | |||

| grondilu | how do I reverse an array? from <a b> how do I get { "a" => 0, "b" => 1 } ? I thought .pairs.invert.hash would work but apparently not | 18:03 | |
|
18:04
reportable6 joined
|
|||
| [Coke] | m: my @a=<a b>; dd @a.kv.reverse.Hash | 18:05 | |
| camelia | Hash % = {:a(0), :b(1)} | ||
| [Coke] | kv is probably faster/cheaper than doing pairs. | 18:06 | |
| immediate | m: say <a b>.antipairs.Hash | ||
| camelia | {a => 0, b => 1} | ||
| [Coke] | even better. :) | ||
| grondilu | nice, never seen .antipairs before | ||
| [Coke] | if you wanted to manually do the pairs, you'd need to invert the pairs themselves, you're inverted the list of paris. | ||
| *you've | 18:07 | ||
| grondilu | unrelated: wasn't there a `=finished` directive to comment everything from here to EOF? | 18:10 | |
| lizmat | =finish | 18:14 | |
| which oddly does not appear to findable on docs.raku.org | 18:15 | ||
| [Coke] | not documented on docs.raku.org/language/pod | 18:18 | |

| grondilu | damn I think I will never understand grammars :( | 18:56 | |
| m: say "000" ~~ /0*<digit>+/ | 18:57 | ||
| camelia | ļ½¢000ļ½£ digit => ļ½¢0ļ½£ |
||
| grondilu | ^this I understand, but then... | ||
| codesections | does anyone have access to a Windows install handy? This SO question (stackoverflow.com/questions/691919...ty-in-repl ) makes me think that `$PATH` might not be set properly in Windows | ||
| grondilu | m: ay grammar { token TOP { <leading-zeros><digit>+ }; token leading-zeros { 0* } }.parse: "000" | ||
| camelia | 5===SORRY!5=== Error while compiling <tmp> Undeclared routine: ay used at line 1 |
||
| grondilu | m: say grammar { token TOP { <leading-zeros><digit>+ }; token leading-zeros { 0* } }.parse: "000" | 18:58 | |
| camelia | Nil | ||
| grondilu | isn't it supposed to be the same thing? | ||
| codesections | m: say grammar { regex TOP { <leading-zeros><digit>+ }; regex leading-zeros { 0* } }.parse: "000" | 18:59 | |
| camelia | ļ½¢000ļ½£ leading-zeros => ļ½¢00ļ½£ digit => ļ½¢0ļ½£ |
||
| grondilu | ok, can you explain to me why it doesn't work with tokens? | 19:00 | |
| oh I see | 19:02 | ||
| "Regex methods are slow but thorough, they will look back in the string and really try." | |||
| codesections | grondilu: yep! token { 'some pattern' } is like regex { :ratchet 'some pattern' } see docs.raku.org/language/regexes#Nam...ion_syntax | ||
| grondilu | so tokens don't backtrack. got it. | ||
| codesections | which means the token version matches "0001" just fine | 19:04 | |
| grondilu | it's really not a token that I'm parsing, now that I think about it. | ||

| grondilu | hum... wasn't there a way to cut a long sequence of method calls into several lines? I can't make it work anymore. | 19:23 | |
| do I have to backslash the newlines? | 19:24 | ||
| lizmat | you can put whitespace between the invocant and the method nowadays | 19:25 | |
| m: dd 42 .Str | 19:26 | ||
| camelia | "42" | ||
| moon-child | lizmat: I have had problems with doing that in the (recent) past | ||
| lizmat | grondilu ^^ | ||
| grondilu | but no newlines apparently | ||
| lizmat | yes, they can be newlines, afaik | ||
| moon-child | however you can use ==> instead in some cases | ||
| gfldex | grondilu: in doubt you can use \ to quote the newline | 19:27 | |
| grondilu | but that is very ugly | ||
| it used to work fine and was very nice | 19:28 | ||
| gfldex | still work if you do `42ā¤.say` but not for `42.ā¤say` | 19:30 | |
| lizmat | grondilu: please provide an example where it doesn't work | ||
| then we can submit a bug report :-) | |||
| codesections | A backslash is also required in *any* "method" in the chain is really a sub being called *as* a method. | 19:34 | |
| m: sub add1 {$_ + 1}; 5.5.round.&add1.say; # doesn't work with newlines/spaces without \ | 19:35 | ||
| camelia | Too many positionals passed; expected 0 arguments but got 1 in sub add1 at <tmp> line 1 in block <unit> at <tmp> line 1 |
||
| codesections | m: sub add1($_) {$_ + 1}; 5.5.round.&add1.say; # doesn't work with newlines/spaces without \ | ||

| immediate | What is the meaning of a twigil-less variable that is declared with `has` in a class? | 19:39 | |
| e.g., `class A { has $val }` | |||
| This answer is where I saw it: stackoverflow.com/a/62969222 | 19:40 | ||
| xinming | releasable6: status | 19:46 | |
| releasable6 | xinming, Next release in ā2 days and ā23 hours. There are no known blockers. Changelog for this release was not started yet | ||
| xinming, Details: gist.github.com/fdb6dacf285b68e53f...eb0e958666 | |||
| grondilu | gist.github.com/grondilu/b35ede989...8c84c99a7b | 19:52 | |
| I could probably trim it more but oh well | 19:53 | ||
| gfldex | m: class C { has $a; }; say C.^attributes; | 19:54 | |
| camelia | (Mu $!a) | ||
| gfldex | immediate: ^^^ | ||
| codesections | gfldex: I noticed that too, but it left me more confused rather than less. Are you saying that `has $a` is an exact synonym for `has $!a`? If so, I've sure been writing a lot of needless !s | 19:56 | |
| gfldex | codesections: I didn't check Roast but the docs don't mention this form, so this might be an artifact. | 19:57 | |
| moon-child | roast has it | 19:58 | |
| codesections | hmm, so it's just missing from the docs? | ||
| moon-child | S12-attributes/instance.t, S12-class/attributes.t, S03-binding/attributes.t | ||
| gfldex | looks like it | 19:59 | |
| And it's likely not the last ENODOC. Raku is BIG! | 20:00 | ||
