BenGoldberg .tell pukku You said you are interested in a DOM manipulator which doesn't change the order of attributes when you stringify it... first, look at github.com/zostay/perl6-ArrayHash; then, look at DOM::Tiny, specifically the source of DOM::Tiny::HTML. Note that there are precisely three places where Hash.new is used; if these were changed to ArrayHash, I'm 99% sure that you'd have a solution.
yoleaux BenGoldberg: I'll pass your message to pukku.

BenGoldberg Aha! I've got an idea for a possible solution for the NativeCall callback memory leak problem. 01:13
Basically, add a method ^parameterize(Mu:U \p, Signature:D $s) to NativeCall::Types::Pointer, which mixes something into Pointer so that two-way marshalling of perl Callables and C function pointers can happen, *and* when it goes out of scope, that's the moment when stuff gets freed. 01:14

Calling XFetchBytes(List) will never work with declared signature (Str:D $display, int32 $length --> Str)
samcv Todd, can you share some code and i can try it out 06:30
ufobat Todd, are you calling it like this XFetchBytes ("foo", 1)
Todd What is the best way to send it? eMail it to [email@hidden.address] ?? 06:31
ufobat gist.github.com/ maybe?
Todd I can probably shorten it to four lines and place it here

Todd In the C world "int *nbytes_return" means a pointer to address on an "int", which is a form of Integer, probably 32 bit. 06:52

Todd Reading 07:30
07:31 wamba left 07:32 xtreak left
Todd so the ":D" means to use "defined". So "Str:D" means to only use "defined strings". Would "int:D" mean to only use a "defined integer"?? 07:33
And what would the difference be between "Str" and "Str:D"? Is one short hand for the other?
ufobat my Str $foo; and now $foo is undefined 07:34
07:34 mcmillhj left
ufobat m: my Str:D $foo; 07:34

ufobat Str means string but you dont care whether it is defined or not. with :U or :D you do care 07:35
07:35 xtreak joined
Todd by "defined", do you mean it has a "my", or do you mean "initialized"? 07:37
ufobat it is more "initialized"
Todd "more" 07:38
"more"?
ufobat but thats not perfectly true, because something that is initialized can set to a "undefined" value afterwards, it is/was still initilized, right?
Todd Here is where I am confused. In the C code "char *XDisplayName(char *string);" , "char *string" is a C pointer to a string. 07:39
07:39 mcmillhj joined
Todd In Native call, it gets changed to 07:40
sub XDisplayName(Str:D $name) is native('X11') returns Str { * };
ufobat i think in C you could do a: char *string;
Todd What is confusing me is how does native Call know to translate the value i am sending it to a C pointer and does "Str:D" have anythingto do with that? 07:41
ufobat this pointer points to nowhere now? right?, thats probably the equivalent of Str:U in this example
samcv `my $var` => undefined `my $var = 'blah'`
Todd sam, what are you trying to tell me? 07:42
Does the ":U" mean "undefined"?
ufobat i dont know NativeCall yet, but i'd assume that Str:D would convert to a char * The Documentation said (C String) docs.perl6.org/language/nativecall...ing_Values 07:43
is this a char *?
yeah :U is undefined
07:44 mcmillhj left
Todd so "my $var;" is just shothand for "my Str:U $var;" ???? 07:45
ufobat no 07:47
my $var; <- now ware could be anything
s/ware/$var/
Todd So what exactly is a "Defined string (Str:D)"? Is the purpose to undo conversatoins with other languages that are not “lexiconical”? 07:48
samcv defined string is any string that has been defined
m: my Str $thing #this string is undefined
camelia ( no output )
samcv m: my Str $thing; say $thing.WHAT; #this string is undefined
camelia (Str)
ufobat for example real world person allways have a Str:D $name 07:49
samcv Todd, yeah the :U means undefined
ufobat whereas pets sometimes have no name, so Str $name would be appropriate
samcv pets?
ufobat ever called your cat at home just "cat"?
Todd would not [my $var = "hello"] define it as a "Str:D"?
samcv i see your point ufobat 07:50
yes Todd
07:50 sunnavy joined
samcv an empty string is defined, but is coerces to False 07:50
for example. and 0 as a number is defined but evals as False
07:50 mcmillhj joined
Todd So how does C know "Str:D $name" is a C pointer to a string (array of characters)? 07:51
07:51 bjz left
samcv though there's `Nil` which is an undefined value. but that's a little different. but there's several ways something can not be defined 07:51
when programming in perl 6? well there's a translation layer
MoarVM uses dyncall library to do it 07:52
Todd Does it figure it out on its own? What is a pointer and what is not?
Be nice if it did 07:53
samcv yeah it mostly does Todd
i mean as long as you actually supply the correct types
like if you try using a string when the C function wants an integer, weird things happen
or if you use the wrong size of integer or whatever 07:54
Todd I think I am not providing the correct types.
samcv show me your code again?
Todd Will do. I has gotten more complex
samcv also you may be interesting in gpxtrixie which will create a bunch of code for you. it's not always 100% correct. but you can take what you need and leave the rest. you'll need clang and uh some other thing 07:55
it supports gcc but i never have gotten it working with that

Todd I will look a gptrixie 07:57
did vpaste work?
samcv yep. also which part is not working 07:58
Todd Calling XStoreBytes(List) will never work with declared signature (Str:D $display, Str:D $str, int32:D $len) in method CALL-ME at /usr/share/perl6/sources/24DD121B5B4774C04A7084827BFAD92199756E03 (NativeCall) line 326 in block <unit> at ./XFetchBytesTest.pl6 line 39
It does not like the way I am declaring (Str:D $display, Str:D $str, int32:D $len) 07:59
# XStoreBytes(displayptr, string, numbytes) sub XStoreBytes(Str:D $display, Str:D $str, int32:D $len) is native('X11') { * }
Do you feel safe running my code? 08:00
samcv yeah i read it. code is fine
I get this printed out: `$Display = <:0>`
seems accurate
Todd The first native call works. I put it in to help figure out the other two 08:01
samcv ah
08:01 mcmillhj left
samcv ok so it's XStoreBytes that doesn't work 08:01
ok yeah it's returning a Display pointer 08:02
Todd yes. If you comment it out, XFetchBytes is whining too.
samcv looks like you need a command to get the Display* and then use that to fetch and store bytes 08:03
since it wants a display pointer
08:04 bwisti left
Todd I thought it was either to hard code ":0.0" or to send it the result in $Display. 08:04
NativeCall would change it over to a C pointer 08:05
samcv i think it may be a special C type. but at minimum i know it's a pointer
the XDisplayName returns a char * not a Display *
Todd In my case it returns four characters, not one. 08:06
samcv XDisplayName you mean?
Todd Yes, maybe it is look for an integer? 08:07
samcv no that seems fine. the problem is that you don't want the display name, you want the display pointer
Todd not ":0.0"
samcv some special object
so you need something that returns a Display *

samcv Todd, ftp://www.x.org/pub/xorg/X11R7.5/doc/man/man3/XOpenDisplay.3.html looks like you want this 08:08
you give it a char * aka a string of the display name, then it gives you back a Display *
which you can use for the other calls
Todd by chance is "char" is C short hand for "array of characters"? In Modula2 (where I come from), "char" is a single byte 08:09
samcv yep exactly a char * is an array of characters and a char is defined as one bytes 08:10
that holds a ascii number usually. though you can store utf-8 in a char *
Todd so "char *" is an array of characters and "*char" is a pointer to either an array of characters or a single character? 08:11
samcv no they are the same thing 08:12
char* and char * are the same thing
err wait
where do you see *char
Todd so "char *XDisplayName(char *string);" means it is returning a pointer to an array of characters and I am supplying it a pointer to an array of characters 08:13
?
samcv yep
exactly
Todd And NativeCall get the dubious task of unravelling it? 08:14
samcv yep
Todd So "char *XFetchBytes(Display *display, int *nbytes_return)" means
1) it will return a pointer to an array of characters
samcv yeah that * is attached to the 'char' not the function name btw
char* XFetchBytes is what most people would write 08:15
or a space or something, not attach it to the other thing
Todd 2) I will provide is some unkown type called "Display *display"
samcv yes that is a pointer to a display object
i assume it's similar to what would be a filehandle. since you have to open the display before you can use any of the functions 08:16
Todd 3) "int *nbytes_return" will tell me how long the returned array of characters is
samcv so think of it like that
08:16 mcmillhj left
samcv yeah you give it a pointer to an int, and it puts the correct value in there 08:17
Todd So what is the type I shospecify in Native Call for the return lenth or just let Natice call figure it out?
samcv so that value will probably change after you run it
wait what did you say in that last sentence?
length? uh. it just says int so i'd just make it an int or something. though Int might work too 08:18
Todd I am trying to figure out hwo to tell NativeCall that I want it to turn those two pointers into a Perl string
samcv you had it say returns Str right? 08:19
that should be all you need
Todd yes
08:19 wamba joined
Todd I want those two pointer turned into a perl string 08:20
samcv well you get the actual string back always if you have it return a Str
only if you made it say "returns Pointer" would you get a pointer
which is not as useful to you
NativeCall::Types::Pointer<0x55da56b3d490> 08:21
$Display = <:0>
that seemed to work fine
gist.github.com/0f84ddcac905b40d57...d7ffb72b45 at least i know i got a pointer back. so that's nice
Todd I am testing something interesting. hold a sec
08:22 n1ce left, mcmillhj joined
samcv but for XFetchBytes you need $display to be a Pointer not a Str 08:23

poop!
samcv did you try and take bytes 08:25
without giving it any
El_Che it's been a while since I tried nativecall, but it was fun

Todd I have been looking at 08:48
docs.perl6.org/language/nativecall.html
and although it is very verbose, it does not show what the C call looks like and how to was rewritten in NativeCall. That is a YUUUGE oversight. 08:49
samcv idk if it supports returning integer pointers, but i haven't tried that before
Yuge
Todd Isn't NativeCall suppose to turn all those pointer into real values? 08:50
It occures to me that I may not be calling the correct C line to read the clipboard
samcv well i've only tried it for char * and some other pointer types
Todd and I may be doign the seg fault to myself 08:51
samcv i don't think that one is related to clipboard but

maybe this is what you want
Todd Wasn't helpful as it did not give the hooks. Rats! 08:55
samcv it looks fairly complicated 08:56
to do X11 clipboard if you read the section
but i would try installing github.com/jtanx/libclipboard and then using that api to get the clipboard. because it's pretty damn involved
then use their nice api to get clipboard

you can skip running a shell and run the program directly
09:04 mcmillhj joined
Todd This guy? docs.perl6.org/syntax/proc 09:04

i would try run
run 'xclip', '-p'; then that should do what you want
Todd Maybe it is all the C code tonight, but gee wiz the proc page is confusing. 09:05
samcv well there's more to it i guess
El_Che samcv: did you get a camelia sticker? 09:06

did somebody mail me one?
El_Che I hoped so, but it doesn't look that way 09:07

Woodi_ I think it is important when you helping and when someone is trying to abuses good heart...
cale2 "Nobody opens an issue or a pull request when they’re satisfied with your work"
Is that normal? I thought that's what stars were for
moritz stars get much less attention 15:27
then issues/pull requests
timotimo i very rarely use the star feature on github
moritz fwiw I try to be happy about pull requests and bug reports, because it means somebody cares about my stuff
and sometimes I manage to do that :-)
timotimo yeah 15:28
Woodi_ cale2: that's other problem :) good is taked for granted :) hard to appreciate that...

stmuk I think there is a pragma
timotimo pragma isn't good enough for what i want to do
nine What do you want to do?
timotimo i'm looking to help our perl6-debugger users put breakpoints into other modules
for that to work these other modules have to go through perl6-debugger's Compiler instance, too 15:31
because it generates different code, i.e. calls into the debugger after every line
cale2 moritz: success is definitely exponential. Or it feels that way. It feels like I was working in a factory and studying just yesterday

naxieAlDle “Nobody opens an issue or a pull request when they’re satisfied with your work” – no, it simply means that nobody is using your project :P 15:37
moritz but I can totally relate to the feeling 15:38
naxieAlDle and if somebody found something lacking, then you simply have a user… 15:39
timotimo nine: i see! 15:40
cale2 that's a good point 15:41
timotimo at some point we'll surely want a debugger that understands moarvm bytecode and its line annotations and such 15:43
15:43 bdmatatu joined
timotimo perhaps an implementation that instruments the bytecode using the spesh architecture 15:43
that particular piece of infrastructure has seen many uses so far, it's pretty neat

timotimo yes, splice
it'd probably be good to point towards splice from that entry 15:57
also, you can use grep :) 15:58
cale2 I'm using grep to find the thing to delete 15:59
@wrong-answer.=splice(@wrong-answer.grep($correct-answer, :k), 1);
pretty verbose :/
timotimo wait, you're using grep, but you're also using :delete?
did you perhaps mean "first" instead of "grep"? 16:00
cale2 It was previously @wrong-answer[@wrong-answer.grep($correct-answer, :k)]:delete;
Sad there isn't a pretty way to do this
timotimo so why don't you @wrong-answer.grep(* ~~ !$correct-answer)?
jnthn Maybe: @wrong-answer .= grep: * !=== $correct-answer;
timotimo er, why did i put the ! there 16:01
jnthn Or !~~ depending on what you want
cale2 Oh that would work
SmokeMachine naxieAlDle: great bot! What do you think if when you give more than one char it make the tables with more than one value column? Not more tables for each char?
timotimo oooh 16:02
that could be neat

16:20 firestarter joined
firestarter hey guys 16:20
timotimo greetings
firestarter i have a question for you
timotimo are you going to ask me a very personal question?
(just a dumb joke) 16:21
firestarter this time it will be professional, if you don't mind
:)
i have a grammar, which has a proto TOP token
and when i call parse with an actions class 16:22
the TOP method on my actions doesn't get called
but when i change the TOP regex into a non-proto version, it gets called
timotimo you have a method "TOP" in both cases, yeah?
firestarter yes
16:22 araraloren joined
timotimo i recall there was a stackoverflow question about proto tokens and their interaction with action methods recently 16:23
jnthn A proto just delegates to one of the candidates, so the methods are also per candidate
timotimo right, was about to say that
jnthn So you'd write a method TOP:sym<foo>($/) { ... } etc.
timotimo so you'd have a multiple methods in your action class
firestarter wow, didn't know that
IOninja timotimo: don't worry, you're not really going to ask them anything? :)
firestarter is it possible to consolidate these methods without explicitly specifying all of them?
i'm talking about the action methods 16:24
skids You could break the proto out to a level below TOP and make TOP just call that rule, then put an action on TOP.
jnthn Alternatively, don't use a proto but just an alternation in TOP instead 16:25
timotimo IOninja: :D
jnthn Protos are actually just a way of spreading an alternation out into a bunch of methods, to allow extension/overriding in subclasses and/or to make it easy to process the different branches differently in the actions 16:26
IOninja swaps the brains of modules.perl6.org... 16:27
timotimo uh oh! :)
firestarter thanks for the explanation

timotimo so, uh, S05-subst*/match.rakudo.moar ... is it supposed to fail right now? 16:28
IOninja firestarter: copius amounts of `dd`
timotimo lichtkind: it allows you to use EVAL with things other than constant strings
jnthn firestarter: If it's a grammar you're debugging, see Grammar::Tracer
skids firestarter: Also be aware of RT#125374

lichtkind ah like sledge hammer: trust me im know hwat i do
thank you
araraloren It's not recommend use EVAL ~
IOninja lichtkind: it's handier when you're doing a regex and some token you're interpolating is evaled as a code. Such uses might be hard to spot even if you *do* know what you're doing.
DrForr "Trust me, I know what I'm doing." Rarely have more dangerous words been uttered. 16:30

it's weird that it doesn't require a sigil on it 16:51

IOninja cale2: what issue? 17:34
oh there comments
[Coke] What do you expect @lines.split(" - ") to do? 17:35
timotimo hah
17:35 girafe joined
[Coke] split works on a Str, not an Array 17:35
timotimo split is a Str method, it'll call @lines.Str for you before it .split s
IOninja cale2: @lines.split(" - ") treats your array as one bigass string
17:36 Ven left
lizmat cale2: how about: my %h = @lines.map( { |.split(" - ") } ) 17:37
cale2 Even when I tried @lines>>.split it did the same thing
IOninja cale2: say @lines».split(" - ").flat.flat.Hash;
lizmat cale2: how about: my %h = @lines.map( { |.split(" - ") } )
IOninja cale2: right, 'cause you're still .Hashing a list of lines (a list of lists)... not a list of splits
17:38 Ven joined
[Coke] wonder if we could write a diagnostic module that would warn you when something got coerced. 17:38
cale2 What I want to understand is how the first method is different from the others
[Coke] (via a sig.)
IOninja cale2: the first method you're processing each line one-by-one. In the others you're processing all of them in one statement
[Coke] in the first one, you're iterating over lines workingon the elements. in the latter, you're converting the arrya intoa single string and workign on that 17:39
[Coke] taps out and lets IOninja handle this. )
cale2 .split(" - ").Hash.say for @lines; @lines>>.split(" - ").Hash.say;
those two should be the same. Just a difference of where @lines goes 17:40
[Coke] none of your code has >>. , btw.
IOninja They're not the same
timotimo very different, actually
lizmat my %h = @lines.map( { |.split(" - ") } ) # loop over all lines, map each line to its split, and slip that: the result is a sequence of key,value,key,value that can serve as the initialization of a hash
IOninja cale2: in first one, you're calling .Hash on result of split. In second one you're calling it on @lines
cale2: on lines from @lines, now split.
cale2: the ». applies only to that one method calls, further method calls are called on the list 17:41
lizmat feels like she is talking to a well and decides to shut up about this
timotimo IOninja: calling .Hash on *results* of .split ;)
IOninja lizmat: I tried your method and it works FWIW :)
17:41 khw joined
moritz The Lizmat Method works! 17:42
naxieAlDle SmokeMachine: join #whateverable :) 17:43
cale2 ahhh
so this should work: @lines>>.split(" - ")>>.Hash.say;
and it does :)
IOninja timotimo: on a list with those results...
lizmat cale2: but it doesn't create a single hash 17:44
it creates a hash for each line
timotimo IOninja: in the first one, the one with a "for @lines" at the end, you're calling .Hash for every line, rather than once
i wanted to make that clear, so i thought i'd suggest "results" instead of "result"
cale2 this works though 17:45
my %data = @lines>>.split(" - ")>>.Hash; say %data;
IOninja timotimo: but there's only one result -_- exactly because it's called everyba vsdf/t.ljka;;'
cale2 The question is now which version is more intelligible. I like lizmat's, but the flat operator is confusing there
timotimo now you're putting a list of hashes into %data; does that give you what you want?

IOninja perlpilot: what's a "staging area"? 18:14
cale2 a dev environment? 18:15
perlpilot Just a place where we can deploy code for testing with a wider audience without affecting modules.perl6.org
IOninja perlpilot: no, we don't. The current modules.perl6.org is meant to be temporary in the first place. :/ 18:16
Based on the update log it *was* the build script that was inserting dupes.
perlpilot IOninja: you know how many "temporary" things have been in place for decades?
IOninja perlpilot: how many? 18:17
perlpilot lots
IOninja Stupid.
perlpilot temporary is an intent that isn't always fulfilled.
IOninja It's somewhat good though. Perl 6 is now more reasonable to use for the ecosystem website than it was 1.5 years ago 18:18

sprocket hello, #perl6! 19:36
moritz \o
sprocket i’ve got a question about gather/take - i’ve having difficulties getting it to construct a lazy list
that’s assuming it’s able to do that, which i thought it was :) 19:37
moritz it is
sprocket so it’s likely something i’ve done?
ok
moritz but you shouldn't assign it to an array in the end, that might be eager
(just guessing here)
sprocket ah, ok, i’m doing that
would that force non-laziness?
moritz m: my \result = gather for ^5 { take $_; say $_ }; my $x = result[2]
camelia 0

moritz sprocket: yes, unless it can detect it's infinite (if I remember correctly) 19:38

IOninja heh
I always thoughht it were an internal method :)
gfldex so .is-lazy controls if .lazy is called and I can set force that with .lazy-if(1) 19:46
i will check roast
IOninja I'm no experct, but I saw it as: .lazy-if(1) is a way to make .is-lazy === True; and when it isn't, assigning to an array is eager; no .lazy calls involved. 19:47

camelia True
IOninja "Built-in operations that know that they can produce infinitely many values return True here, for example (1..6).roll(*)."
But it won't produce infinitely many!
oh
OK, never mind :)
So many things are lazy, and .is-lazy should really be named .is-infinite 19:52
gfldex things can be lazy but not infinite 19:53
or better a .is-lazy can throw EndIteration
IOninja gfldex: what's lazy?
huh
19:54 Ven joined
gfldex lazy just means that the generation/computation/fatching of values happens out-of-order 19:54
maybe even concurrent
IOninja huh
moritz erm, nope
IOninja What do you mean out of order?
naxieAlDle yea, this discussion again…
moritz lazy doesn't do concurrent
gfldex not by itself 19:55
naxieAlDle how many times we had it? And the conclusion has always been that is-lazy is broken anyway :)
gfldex but I can make it :)
IOninja naxieAlDle: was it the group's conclusion or your own?
gfldex IOninja: as soon as there is something lazy about the execution of commands breaks normal control flow. You can't depend on a call tree anymore.
naxieAlDle IOninja: nobody was ever able to define what it does. The conclusion is my own :P
IOninja moritz: so why are some things lazy but their .is-lazy is False?
m: my $s = gather for ^10 { take $_; say $_ }; say $s.is-lazy; $s[2] 19:56
camelia False

IOninja moritz: ^ like there. Values are lazily generated... are they not?
gfldex: what's "lazy"?
moritz IOninja: I don't know in this specific case; I'd have expected gather/take to be always lazy 19:57
gfldex IOninja: "lazy" is an abstract concept and as such does not exist
IOninja gfldex: what do you mean by the word when you used it above?
gfldex m: Channel.new.is-lazy.say
camelia False
gfldex that channel could very well be lazy even if it pretends not to be 19:58
IOninja naxieAlDle: I'm starting to share your feelings on the subject.
gfldex IOninja: the Perl 6 behaviour tied to that concept
IOninja gfldex: and what is it?
moritz we mark known infinite lists with is-lazy, and those that the user explicitly requested to be lazy 19:59
naxieAlDle IOninja: thing is, once we define what it should do, we will be able to file a couple of bug reports… and eventually it will start making sense
moritz it's far from perfect, but nobody has yet suggested a better heuristic or solution
IOninja moritz: so .is-lazy is a misnomer? It should be named .is-infinite?
gfldex IOninja: the result of continuations provided by gather/take and iterator trickery
IOninja gfldex: ok, then if gather/take is lazy, why does its .is-lazy is False by default? 20:00
moritz IOninja: not really; "lazy gather for ^5 { take _$ }" is not inifnite
but explicitly lazy
IOninja moritz: but it'
moritz: but it's lazy without explicity.
gfldex IOninja: i consider .is-lazy a hint to the compiler, not myself 20:01
moritz IOninja: it's lazier with it :-)
gfldex (well the runtime aswell)
moritz IOninja: like, assignment to an array interprets one case eagerly, and other lazily
IOninja but why?
moritz performance 20:02
lazy lists are rather expensive
so we try to only use laziness when we need it
IOninja Makes no sense to me to overload term "laziness" this way.
naxieAlDle m: say (1..99999999999999999999999999999999).is-lazy 20:03
camelia False
moritz we could totally make an assignment like my @a = 1..10; lazy, but accessing @a would be very slow
Geth doc: 3719d5fab0 | (Wenzel P. P. Peppmeyer)++ | doc/Language/list.pod6
wrong method was wrong
naxieAlDle m: say (1..∞).is-lazy
camelia True
gfldex the whole section is shitty
gfldex takes notes
naxieAlDle IOninja: maybe we should start a table somewhere 20:04
IOninja naxieAlDle: what sort of table?
naxieAlDle IOninja: with a list of things that are .is-lazy and things that are not
moritz maybe we'd be better off by making the whole lazy vs. eager thing explicit
IOninja no
gfldex naxieAlDle: alcohol is a solvent, not a solution
moritz but then stuff like my @a = 1..*; would hang
gfldex ohh, that kind of table 20:05
IOninja So far I see it entirely as a terminology problem.

22:07 Actualeyes left
jnthn Todd: If you're going to use | you need a shell 22:09
Since | is interpreted by the shell
And run explicitly is not using a shell
moritz that's what shell is for :-) 22:10
jnthn Though looking at what you're doing, it seems it'd perhaps be better to pass :in to run and then write to the stdin of the process, however that's done
Todd rats. Is there a way to send "standard in" to xclip other than with a pipe? 22:11
oh! How do I do that?
22:11 mcmillhj left
jnthn Don't know off hand, though should be in the docs 22:12
gfldex docs.perl6.org/type/Proc$COLON$COLONAsync
jnthn I know for Proc::Async you do something like Proc::Async.new('xclip', 'args'..., :w) 22:13

Make sure that the raw table is aligned correctly

I don't think anybody needs the unrendered version, but it does not take much to generate it beautifully.

Escape | in markdown tables

It seems that this is the only way to do it. Meh.
jnthn And then you can .print once the process is started

Geth modules.perl6.org/tag-fixes: febbf164eb | (Zoffix Znet)++ | lib/ModulesPerl6/Model/Dists/Schema/Result/Dist.pm
Fix duplication of modules during db update run

The tag work changed primary key of Dist table and this made
  ->update_or_create fail to update existing stuff, since we're not
passing it the primary key. So it dupes the modules during build, and at the end of the build the originals get assumed to be old, deleted dists and are tossed.
Fix by using meta URL as primary column.		 23:30

Todd In the vpaste.net/Dx11Y code the commented out qx will read until the end, but the run method stops at the first line feed. Is there a was to get run to read the whole thing? I am reading a column of data 23:34
IOninja .. 23:36
Todd: use the same method as you use on qx//?
Todd: .get gets one line. Use .lines in that place and toss $Str.lines
Todd Thank you! 23:40

samcv hello Todd 23:50
IOninja Todd: what perl6 version you got?
samcv if you're making the proc object with `run` then you don't need to .start
timotimo if it's a Proc::Async, you need to tap the .out which i sa supply 23:52
IOninja FWIW the link to code in question is just a few lines above.

IOninja Todd: what version are you using? 23:53
Todd $ rpm -qa rak\* rakudo-star-0.0.2016.11-1.el7.x86_64
MasterDuke shouldn't checking the status happen before getting the output?
samcv it's just a proc object not a procasync timotimo 23:54
timotimo OK
anyway, i'm enhancing that error message
Todd yum says no updates to rakudo-star
timotimo oh yum 23:55
IOninja Todd: just swap it to .out.slurp.lines
timotimo please give us perl6 --version
Todd $ perl6 --version This is Rakudo version 2016.11 built on MoarVM version 2016.11 implementing Perl 6.c.
IOninja Todd: works fine on latest Perl 6 and there were fixes to .lines since your version

Todd That worked! Thank you!
IOninja any time
timotimo moarvm's latest commit will give you the type name and what repr the thing in question had 23:59
Todd My primary is Scientific Linux 7.3. The Fedora machine I work on a lot is $ perl6 -version This is Rakudo version 2017.01 built on MoarVM version 2017.01 implementing Perl 6.c.
naxieAlDle hm, why not out.lines ?
IOninja -_-
samcv great that's the newest star
