maybe that's just me
lookatme yeah, maybe help when run some external tools 01:45
Zoffix Just needed it for first time here: github.com/zoffixznet/rdev/blob/ma...#L126-L130 01:46

Zoffix AlexDaniel: I solved the issue of release delays being hard to work with: irclog.perlgeek.de/perl6/2017-12-20#i_15602495 02:00
Or rather, I will, the next time it happens. Just gonna add a command to my Z-Script Awesome Rakudo Build Helper :) 02:01
It already does the separate-checkouts stuff.
Z-Script being this: github.com/zoffixznet/rdev 02:02
It's so awesome, I can't believe it took me a year to make it :)
AlexDaniel Zoffix: fwiw some of the stuff in rdev I kinda want to see in the main makefile… :) Not sure if that's a good idea but grrr, a separate script to do the basics 🤷
Zoffix Yeah, maybe. But the maintenance burden for it is a lot lower than a makefile 02:03
AlexDaniel sure. Maybe later when it's stable?
Zoffix Well, at least for me, since I know Perl 6 but not makefile/bash :)

Guest49524 how do you get the path of the script you are running? 06:07
Zoffix $*PROGRAM 06:08
huggable: FindBin
huggable Zoffix, use lib $*PROGRAM.sibling: '../lib'; # finds lib/ for scripts in bin/ or t/
Guest49524 is there a docs page for it? I need the full path 06:11
Zoffix Guest49524: $*PROGRAM.absolute
Guest49524: it's an IO::Path object
huggable: IO::Path
huggable Zoffix, File or directory path: docs.perl6.org/type/IO::Path
Guest49524 $*PROGRAM.absolute.IO.dirname 06:25
Zoffix Guest49524: what are you trying to do?
Guest49524 is there a shorter way to do that?
get the directory path of the running script without me knowing what directory it is? 06:26
Zoffix Yeah, but then what are you doing with it?
Guest49524 there is a directory in that directory with files for the script to use
Zoffix Guest49524: $*PROGRAM.sibling('directory-with-files-to-use') 06:27
There's also .parent and .add methods you can use to "navigate" a path (like, transform one path to another) 06:28

Guest49524 which of those is better?
Zoffix :e test is useless, the other two already check existence 07:02
AlexDaniel`: FWIW I see the bot get triggered by stray code more often than by someone forgetting the "m:" irclog.perlgeek.de/perl6/2017-12-26#i_15622312 07:03
Guest49524: and second one has wrong condition; you're testing return value of `say` which is always True 07:05
if shell $script, :out { $^p.out.slurp(:close).say } else { die "Could not run the $script" } 07:07
Well, if you're just `say`ing it, you likely don't need to capture its STDOUT and can just let it be carried forward:
shell $script; # it'll explode automagically when sunk 07:08
Relevant docs: docs.perl6.org/type/Proc#method_new 07:09
Guest49524 but it says the other two fail with X::IO::DoesNotExist ? and is not `or die` like a (try) catch all for exception handling?
Zoffix Guest49524: `fail` means return a Failure object ( docs.perl6.org/type/Failure ) these are "lazy" Exceptions in that they don't explode and get disarmed when evaluated in .Bool context or are tested for .defined'ness and smartmatch (`~~` op) ensures they're not exploded, so `$script ~~ :f & :rwx` will aways give either True or False. 07:12
Guest49524: The `$foo or die` the same as `die unless $foo`. The `or` operator has precedence lower than the precedence of a subcall, so your code is like `say(…) or die` or `die unless say(…)` and say() always returns True, so that'll never die 07:13
07:13 parv joined
Zoffix Guest49524: and no, we don't have the `or die` idiom. That's Perl 5's thing. In Perl 6, many things return Failure objects and they explode when sunk (when used in void context) 07:14

camelia Whoa who whoa.. Looks like something said `boom!`
Zoffix Guest49524: well, yeah, that's what Failures do if you don't "handle" them (evaluate in Bool or defined contexts)
^ like above, `orelse` op handles that Failure because it checks .defined'ness, and so nothing gets thrown 07:17
Bascially Failures let you handle Exceptions using boolean/definedness constructs rather than `try { CATCH {} }` stuff (tho we have that too, if that's your thing)
m: sub do-thing-or-explode { rand > .00001 and fail "boom!"; "no boom this time" }; try { do-thing-or-explode(); CATCH { default { "Whoa who whoa.. Looks like something said `{.message}`".say } } } 07:18
camelia Whoa who whoa.. Looks like something said `boom!`
Zoffix (`try` block automatically enables `use fatal` pragma which lexically makes Failures explosive right away)

timotimo github.com/rakudo/rakudo/commit/dc...35eacb173c - looks like 2017.06 is the first release to haev it 12:35
we should introduce a networking component to rakudo that regularly (once or twice a month) downloads a text file that lists all methods for all core setting classes and what release they first went in on, and then when we get a "method not found" exception for a class in the core setting we should search that file :P 12:36

Summertime for the following: say do loop { state $x = 0; last if ++$x > 2; $x; }; 15:49
why doesn't the state stay... statey? it seems to get reset each loop?
switching to: loop { state $x = 0; last if ++$x > 2; $x.say; } 15:50
the state works, but then you can't get the values out as easily 15:51
moritz Summertime: state behaves like an outer lexical variable
Summertime: if the outer lexical scope is re-entered, the state variable is reset

Summertime that'd be because loop is lazy?

lizmat seems to be some interaction between say and do and loop that causes a new scope to be cloned

Zoffix timotimo: is JSON::Fast shoving {"0": null} for object by-design? 21:26
Zoffix was expecting .Capture to be used
timotimo that doesn't sound right, yeah
well, can't really use capture, because no support for mixed positional and keyed in json objects 21:27
Zoffix Ah
timotimo looks like it uses .keys
and then accesses it via { }

Zoffix bah
Well, doing ».Capture Did The Right Thing with JSON::Fast :)
timotimo it does, eh?
Zoffix star: use JSON::Fast; say to-json (class { has $.x }.new(:x(42)),)».Capture 21:30
camelia [
{
"x": 42
}
]
timotimo how is it supposed to handle things that give both positionals and nameds in the capture?
Zoffix star: use JSON::Fast; say to-json class { method Capture { \(<a b c>, :42foo) } }.Capture 21:31
camelia {
"0": null,
"foo": 42
}
21:31 obfusk joined
timotimo that looks wrong 21:31
Zoffix mhm
timotimo m: say \(<a b c>, :42foo).keys
camelia (0 foo)
timotimo m: say \(\<a b c>, :42foo).keys
camelia (0 foo)
timotimo m: say \(|<a b c>, :42foo).keys
camelia (0 1 2 foo)
timotimo you did the capture wrong :)
but it'll not do the right thing with those keys 21:32
Zoffix star: use JSON::Fast; say to-json class { method Capture { \(|<a b c>, :42foo) } }.Capture
camelia {
"0": null,
"1": null,
"2": null,
"foo": 42
}
timotimo or does json support integer keys?
i don't think it does
moritz it does not
Zoffix FWIW, Perl5's Mojo::JSON and several other JSON modules try to call .TO-JSON on objects they don't recognize 21:33
timotimo hm, yeah, we could implement that in both our json modules
tiny and fast, i mean
moritz Zoffix: .TO_JSON, maybe?
timotimo i'd've maybe said either .Json or .JSON
moritz likes AS-JSON better than TO-JSON 21:34
"to" implies an in-place conversion
Zoffix moritz: they use .TO_JSON yeah, but IMO P6 version should be the status quo kebob-case
timotimo to-json doesn't do that either :)
moritz fwiw JSON::Tiny won't be the first mover when it comes to such a method, but will accept patches if other modules come to a consensus 21:39
it's not JSON::Experimental after all :-) 21:40

timotimo gfldex had found some rather big speed improvements by making all escapes based on \u sequences rather than the different ones we have 21:45
i might be able to combine both approaches, actually 21:47
oh, but that code isn't able to handle surrogate pairs
21:49 leah2 left, Zoffix left, pmurias left
timotimo zoffix, got a good idea for when a capture has both positionals and string keys "0", "1", "2" for example 21:50

timotimo i feared as much :( 22:39
gfldex we have to break those at some point
because that assumption is simply false
timotimo i think i'll steal your str-escape but make it output \t and friends again instead of \u... 22:40

timotimo looks like i found a way to make it rather a bit slower 23:06
um, huh 23:09
gfldex: did you test the str-escape change with strings that have to-be-escaped things in them? because it seems incredibly slow compared to the old code
lizmat m: say Mu ~~ (*); say Mu ~~ Whatever # why the difference ? 23:14
camelia True
False
timotimo gfldex: with my old code it does a 5k string with some special chars in it in just 1.02 seconds, whereas your code spends 112 seconds (this is for to-json-ing the same string 1k times) 23:15
lizmat sleep& 23:16
teatime lizmat: they seem totally different. Mu ~~ Whatever should def. be false. I dunno enough about whatever star to know what Mu ~~ (*) should be, however it's actually False on my 2017.09 install. 23:17
