AlexDaniel not sure how would that make a difference 00:00
samcv idk for my bot i just wrote to a file then ran a command line program on that file
00:00 cdg joined
samcv seems simpler 00:00
AlexDaniel yea but I guess your command line program wasn't a second piece of code its author wrote :) 00:01
samcv yeah

no
AlexDaniel samcv: I do not think this is going to work :| 00:07
samcv there are 108 properties and that is not one of them
samcv double checks just in case
00:07 unicodable6 left
samcv yeah no 00:07
AlexDaniel I'm not sure what happens exactly, but something just eats a lot amount of memory at some point 00:08
phatbot Are you using any regexes? 00:09
samcv it's probably something wrong with HTTP::Tinyish 00:10
phatbot it basically just shells out to `curl`
AlexDaniel phatbot: I don't think so
samcv oh does it?
phatbot Yup
Doesn't even work if curl is not installed 00:11

AlexDaniel samcv: so the question is: what should be done with control characters in gists?
phatbot hehe
samcv it's probably just the null byte doing it
just remove it 00:15
before gisting
AlexDaniel remove or replace with ␦ ?
samcv well... null bytes are against RFC for IRC protocol
you only need to remove the null byte
AlexDaniel hm
samcv just replace with \0
AlexDaniel no, there's a cool character for it 00:16
samcv because NULL is a unicode property name
u: null
AlexDaniel :|
samcv but
phatbot .u ␀
samcv \0 is not any unicode property
yoleaux U+2400 SYMBOL FOR NULL [So] (␀)
samcv while that is
so \0 is not found anywhere in it
00:16 unicodable6 joined
AlexDaniel u: null 00:16
unicodable6 AlexDaniel, U+0000 NULL [Cc] (control character)
AlexDaniel, U+2400 SYMBOL FOR NULL [So] (␀)
AlexDaniel, U+1D159 MUSICAL SYMBOL NULL NOTEHEAD [So] (𝅙)
samcv so just make it \0 00:17
AlexDaniel why not ␀ ??
samcv because that's a different codepoint
AlexDaniel \0 is two different codepoints
samcv yes
so you can tell it's not the literal character
because it doesn't match any unicode name or property
AlexDaniel well, then how would you be able to tell that \0 are not just literal characters 00:18
nah, I'll go with ␀ I think
samcv because there's no \0 unicode character? lol
i would have said NULL but that is a unicode name 00:19

AlexDaniel phatbot: no, it does not work that way. It does not know about new builds before they are actually built 00:24
samcv so yeah it's not working because you are sending the stream to the command that way, sending it with a file would not have the problem
AlexDaniel phatbot: I'll delete it to give it another go, let's see…
samcv: can you open a bug report for HTTP::Tinyish ?
samcv sure
i think i can fix it tho 00:27

samcv oh?
phatbot The original author is pretty skilled in programming, so I doubt there'd be such an obvious issue.
samcv may need the --binary-data 00:29
command line option for curl
i think that's the issue
it's sending it as text
phatbot Right now it uses --data-binary is that the same?
samcv err i meant --data-binary
it does that already hm

phatbot I'm not gonna mangle user's data.
samcv oh ok
phatbot samcv: swap broken JSON encoder to non-broken
samcv i mean the fix is to have json fast replace json the rigth chars
phatbot Surival of the fittest :)

phatbot And Perl 5's JSON::Meth can decode it too, so there's ain't nothing wrong with that json 01:17
I'm glad tho. It makes it a good argument to dissuade people from poking in Rakudo's internals to use built-in JSON encoder to avoid a module dep :P 01:18
01:19 BenGoldberg left
samcv build in json encoder? 01:20
oh json meth is a core module?
phatbot samcv: JSON::Meth is my Perl 5 JSON module.
samcv: we do have a built-in encoder/decoder, but that's just for META files. 01:21
samcv ah k
phatbot hm... OTOH we allow some free-form text content... I bet we choke on something then :/
01:21 BenGoldberg joined
samcv imo from::json should warn but not throw for json that just has errors 01:22
i mean it can still be decoded
with control chararcters in there. even though you are not supposed to do that
phatbot it uses a grammar, so that's just grammar failing

SmokeMachine MasterDuke: I'll explain about generators... I think that was a good idea! 04:35
MasterDuke: but, if you are curious (before I write it) you can take a look if you want: github.com/FCO/Test-Fuzz
MasterDuke: the "generator engine" is here: github.com/FCO/Test-Fuzz/blob/mast...erator.pm6 04:36
MasterDuke: Today I only have generators for Int, UInt and Str... but if you use any type, the Test::Fuzz will try to discover whats the best generators to use... 04:39
MasterDuke: for example: if you use a subset Prime of Int where {.defined or .is-prime}... it will use the Int generator and grep Prime 04:40
MasterDuke: and if you use Any, it will try to discovery every generator that's a subtype of Any (actually all 3 (Int, UInt and Str)) 04:41

psch kalkin-_: in the end, i think this is a trap, not a bug 11:59
kalkin-_ how so?
psch kalkin-_: you don't want a sequence generated from 'foo', ' ' with the following elements extrapolated via the rate of change between 'foo' and ' '
kalkin-_: you want a List that starts with 'foo', and then the sequence from ' ' to '~' 12:00
kalkin-_: unless the result of 'foo', (' ' ... '~') *isn't* what you want
kalkin-_: in that case infix:<...> isn't smart enough to understand what you want 12:01
kalkin-_ yes, but this doesn't explain the <foo>, <a>…<z> case, or does it?

kalkin-_ hmm 12:02
psch kalkin-_: probably for that kind of template stuff phatbot++ was mentioning
kalkin-_: in any case, src/core/operators.pm:105 is what's called by infix:<...> afair
kalkin-_ i see thanks for the explanation and your time 12:03
psch kalkin-_: the problem is, again, really much waterbedding. the template stuff was deemed important and thus works. other cases didn't get thought of (or argued for) as much, so they often are probably surprising 12:04
kalkin-_: like, what *is* the predecedor for 'aaa'?
kalkin-_: and, what's the predecedor for '\x[PILE OF POOP]a'? 12:05
kalkin-_ may be it would make sense to add a template for ASCII sequence
psch *predecessor
kalkin-_ for '\x[PILE OF POOP]a` is chr(ord('\x[PILE OF POOP]') -1) ~ 'a' ?
psch kalkin-_: but that means that the pred for 'aa' is 'za'
erer 12:06
kalkin-_ or actually 'x[PILE OF POOP]`' (because '`' is ascii pred of 'a')
psch ...no it doesn't o.o
kalkin-_ but may be it's not an expected behavior
psch i mean, my last statement was bogus, sorry

sena_kun SmokeMachine, can you provide a link to Test::Fuzz module? Is it on github? 15:16
SmokeMachine sena_kun: sure! github.com/FCO/Test-Fuzz 15:18
sena_kun: but there're no documentation yet... 15:20
:)
perlpilot SmokeMachine: Why "sub MAIN(:$fuzz!)" ? It looks like you were going to do a multi for fuzz and no fuzz, but didn't actually do it.
SmokeMachine perlpilot: you are right!! changing to multi MAIN(... 15:21
sena_kun SmokeMachine, does it use narrowing(?) to find a good edge-case examples or just use simple random values of some type? Ah, probably nevermind me, I'll look into the source. 15:22
perlpilot SmokeMachine: btw, Test::Fuzz is a neat idea.
sena_kun: heh, I was just doing that for the same reason :)
sena_kun Yes, definetely. Any QuickCheck analog is awesome. SmokeMachine++ 15:23
SmokeMachine sena_kun: the generators are hardcoded... so I put some usual edge cases and then a lot of random... for example: for int I use 0, 1, -1, 999999, -9999999, ... 15:24
perlpilot SmokeMachine: you might mention this in your article along with other ideas for generators that your readers could try. (Having pluggable generators would be nice too) 15:25
SmokeMachine perlpilot: thank you (sorry, I'm still searching the meaning of neat...)
perlpilot: that's on my wishlist! 15:26
perlpilot SmokeMachine: I meant "neat" as in "novel, interesting, useful, excellent, I like it, etc." :-)
SmokeMachine perlpilot: thank you!!! (I am sorry for my terrible english!) 15:27

SmokeMachine perlpilot: on the first version of Test::Fuzz it has pluggable generators... (it had a function fuzz-generator() hat receives a generator name and a Positional of values...) but I splitter it in some classes and I loose this feature... but we'll have it back in a future version... 15:31

SmokeMachine perlpilot: Not yet... but I use that to get all possible type objects... 15:41

geekosaur actually there is a serious question there. arguably for most purposes you don't care about Array, you care about Positional, and the @ tells you that 19:59
masak loveperl: what I meant to say was `@arr.WHAT == Array` works, but `@arr ~~ Array` rolls better off the tongue and is inheritance-safe 20:00
geekosaur what problem are you trying to solve?
RabidGravy boo!
loveperl tank you

RabidGravy well you can make it something else but you'd have to try hard at it 20:03

camelia rakudo-moar 3df431: OUTPUT«{:foo("bar")}␤»
masak I think I agree, but... why should it be an error? 20:05
geekosaur because @ tells the programmer to expect a Positiona;l
20:06 sufrostico left
moritz right, @ implies Positional 20:06
masak should `my @a is Set;` also be an error?
geekosaur if that isn't supposed to be meaningful, there comes a question of whether sigils other than $ should even exist
moritz masak: yes
geekosaur sets aren't positional. I'd expect % sigil 20:07
moritz masak: anything that violates the type constraint of the sigil
if we uphold that rule, you can be sure that you can pass an @ to a signature that uses an @
masak hokay -- makes sense
geekosaur actually worse than that: if I just look at the @, I may interpret your `my @a is Set` as meaning an array of sets 20:08
