| samebchase- | I am trying to destructure, i.e. unpack a hash in a `my declaration`, but facing some issues with it. Given `my %hash = 'one' => 1, 'two' => 2;`, why doesn't `my %h2 (:one($o), :two($t)) = %hash;` work if I want to access the value of the 'one' key with the variable `$o`. | 08:08 | |
| could someone point me to the documentation where something like this can be achieved. so far I have not been able to find anything | 08:10 | ||
| I am able to destructure function arguments like this: `sub hs(%h (:one($o), :two($t))) { say $o, $t; }`, but the same syntax is not working with `my`. | 08:13 | ||
| MasterDuke | samebchase: i don't know the answer, but i assume you've looked at docs.raku.org/type/Signature#Destr..._arguments ? | 08:16 | |
| samebchase- | I've been able to get it working with functions, but can't seem to make it work with `my` declarations. | 08:22 | |

| jnthn | samebchase-: You need to use the binding operator (:=) to destructure, not the assignment operator. | 09:38 | |

| brtastic | How long do you think it takes to learn raku above the level raku's equivalent of baby perl? I know the language is vast | 13:33 | |
| moritz | above baby raku: pretty quickly :D | 13:38 | |
| jnthn | Depends if you count in the standard library or just the language, really. | 13:41 | |
| timotimo | there's a part of the standard library you really can't get much done without :P | 13:43 | |
| i mean, Str is in there, and Int, and Array :) | |||

|
|||
| brtastic | with just enough standard library to get most out of the language features, I'm not yet familiar with raku more than creating a lazy array with fibonacci sequence up to infinity but I feel like that's one of the features that can really make the difference | 13:52 | |
| moritz | it can | 13:54 | |
| and you can spend weeks or months learning grammars really well if you're into text parsing | |||
| (though if you're really into parsing, you might learn them a bit faster) | 13:55 | ||
| but if you're not interested in that area, no need to learn that :D | |||

| melezhik | How can I do html escaping in Template::Mojo template? | 20:01 | |
| lizmat | tadzik might know | 20:02 | |
| :-) | |||
| tbrowder | hi, folks | 20:12 | |
| timotimo | don't template languages tend to do escaping by default and need unescaping to be made explicitly | 20:14 | |
| tbrowder | i'm getting travis failures with my Excel module which requires Inline::Perl5. the inline::perl5 shows installing ok in tony-o's nightly but it fails the inline::p5 test | ||
| Grinnz | are you talking about in perl melezhik? | ||

| lizmat | tbrowder: nine did some extensive work in Inline::Perl5 recently, maybe that could be the reason ? | 20:18 | |
| melezhik | I search thought the code and could not find any examples for that | ||
| tbrowder | .tell tony-o yr nightly is failing when installing Inline::Perl5. there is a warning during compilation and then a failure with testing. i don't have a problem installing locally on debian but i don't have access to an ubuntu box | 20:19 | |
| tellable6 | tbrowder, I'll pass your message to tony-o | ||
| Grinnz | not that I personally mind, but it would probably be better if that module did not use the Mojo name implying some relationship to the mojolicious team... maybe MojoLike | ||
| melezhik | yeah, I am not the author | ||
| tbrowder | lizmat: i saw that, but i don't have any prob locally. but as you probably just saw, tony-o's ubuntu nightly show a compiler warning i can't dup on debian buster | 20:21 | |
|
20:21
KindOne joined
|
|||
| Grinnz | additionally I don't want people showing up in #mojo asking about that module ;) | 20:21 | |
| tbrowder | anyone have ubuntu handy to test upinstall inline::perl5? | ||
| *zef install | 20:22 | ||
| lizmat | Grinnz: it's a little late to complain about a module that's been around for 7 years now | 20:23 | |
| melezhik | tbrowder: rakudist has centos/debian/alpine if it helps | ||
| Grinnz | I'm not complaining, just advising | ||
| melezhik | it's quite easy to bootstrap Ubuntu container as well | ||
| lizmat | actually 8 years old tomorrow | ||
| melezhik | yeah, the time I started to use Bailador it was a default templating system for it | 20:24 | |

| slooowly | |||
| p6steve | hi i have three related modules - use'ing them in one sequence works, the other segfaults | 20:27 | |
| how cn i get started in debugging the segfault route - eg stacktrace? | |||
| melezhik | tbrowder: you don't need to install anything, rakudist is a service ready to use | 20:28 | |
| lizmat | p6steve: by the time you segfault, it's too late to create a backtrace, at least at the HLL level | ||
| but timotimo might have some ideas, p6steve | |||
| melezhik | repo.westus.cloudapp.azure.com/rakudist | ||
| p6steve | This is perl 5, version 30, subversion 2 (v5.30.2) built for darwin-thread-multi-2level on macos 10.15.4 | ||
| melezhik | give me 10 minutes and I'll bootstrap ubuntu for you | ||
| tbrowder | melezhik: ah, that was in lizmat's last weekly! i've already used it! | 20:29 | |
| but not for Ec | |||
| Excel | |||
| melezhik | yeah, 10-15 minutes and you'll get ubuntu there | 20:30 | |
| timotimo | it's sometimes possible to get a stacktrace at the point of a segfault | ||
| melezhik | I have probably already run tests for this module | ||
| timotimo | p6steve: please run perl6-gdb-m instead of perl6 (or raku-gdb-m instead of raku) | ||
| tbrowder | p6steve: have you tried isolating the use of the modules into their using scopes? | 20:31 | |

| p6steve | melezhik rakudist is on my radar for wider hardening - would like to get it working all ways on my machine first | 20:33 | |
| timotimo: will try perl6-gdb-m next and report back | 20:34 | ||
| melezhik | p6steve: sure | ||
| timotimo | at the point of the crash, go "up" until the frame it shows has a "tc=0x12341234" in the line | 20:35 | |
| rather than one that's "optimized out" or something | |||
| p6steve | tbrowder: i have three layers Physics::ShortMeasure uses Physics::Measure and Physics::Unit, Physics::Measure uses Physics::Unit | ||
|
20:36
dotdotdot left,
dotdotdot joined
|
|||
| p6steve | tbrowder: and the script uses Physics::Measure and Physics::ShortMeasure | 20:36 | |
| tbrowder: from the base - each module works fine - so Physics::Unit has solo test, then Physics::Measure tests at this level | 20:37 | ||
| trowder: so, my question is "what do you mean by isolating into using scopes"?? | 20:38 | ||
| lizmat | p6steve: use statements are lexical | 20:39 | |
| tbrowder | hm, maybe segregate the chunks a bit more so no overlap, have a physics::longmeasure and no physics::measure..l | ||
| lizmat | m: { use Test }; ok 42 | 20:40 | |
| camelia | 5===SORRY!5=== Error while compiling <tmp> Undeclared routine: ok used at line 1 |
||
| tbrowder | lizmat: instead of putting use statements at the top of the using file of a module, put the use statements inside the using sub | 20:41 | |
| p6steve | lizmat: you are a genius! | 20:42 | |
| tbrowder | sorry, lizmat... | ||
