kjk hello, trying to use the 'rename' sub, but notinced that it returns a failure instead of throwing an exception... Currently I'm calling it like: sink rename ...; is this how it's expected to be used? 02:32
02:33 noganex left
kjk basically I'd it to throw an exception instead of failing silently on me, which seems to be the case if I just call it without "sinking" it. 02:34
02:35 ufobat_ joined
perigrin a) that's possibly a question better suited for #perl-help than #p5p, b) if you want it to throw an exception you probably want to use autodie 02:36
Juerd Sink context is what happens implicitly if you don't use the value
perigrin c)I'm in the wrong damn channel
stupid irssi
perigrin sigh
geekosaur er, this is neither #p5p nor #perl5 :)
whoops
Juerd perigrin: "sink" is Perl 6's void context.
perigrin geekosaur: yeah irssi just renumbered everything on me and I'm an idiot :) 02:37
perigrin moves some things around
geekosaur this is why I don't like irssi and stick to hexchat. channel pane behaves :) 02:38
Juerd kjk: For example, if you assign the return value of rename to a variable, the failure will be assigned. No exception is thrown until you use the value later on. But if you just have a bare function call, it should fail immediately.
02:38 ufobat left
kjk @Juerd right, I wonder why it was decided to return a Failure instead of throwing an Exception 02:38
Juerd kjk: That's the easiest way to enable ignoring the problem if your program doesn't mind 02:39
perigrin geekosaur: it usually isn't a problem unless my host restarts over night without my being aware of it
Juerd kjk: And it's the easiest way to allow simple boolean error handling: rename ... or die "didn't work :("
AlexDaniel` perigrin: this reminds me how one time I was explaining to somebody the difference between "" and '', only to realize that I'm on #python
kjk since I think most people just call it like this: rename from-name to-name; but then that would silently fail :( 02:40
AlexDaniel` perigrin: I ran away once I realized
Juerd kjk: If it would throw an exception, then you would need to actually CATCH the error to get your own error message, or to ignore it.
perigrin I'll own being an idiot. I do it often enough.
Juerd kjk: Actually, that shouldn't fail silently. Can you share the code that does?
geekosaur kjk, if they call it like that, the Failure should be sunk and get thrown
kjk really? hold on I'm sure it didn't get sunk, let me check 02:41
geekosaur if they assign the result, that is a Failure object; testing it as a Boolena lets you see if it succeeded or not as normal flow control instead of as an exception
but using it in any other way should throw the deferred exception
also, for when you really want stuff to just explode immediately, there is 'use fatal' 02:42
AlexDaniel` this reminds me of github.com/perlpilot/p6-sake/issues/12
(lol, everything reminds me)
Juerd wonders if there's implicit returning going on, obscuring the non-sink context through propagation, as in sub mv { rename $^a, $^b }; my $x = mv $foo, $bar; 02:43
AlexDaniel` that's exactly what I'm thinking
02:43 wander left 02:45 itaipu joined
kjk yeah, just read about 'use fatal'. nice. anyway, coming up with a short example to reproduce it 02:46
ok can't reproduce it with new code, I'm just going to share my existing code that has the problem in a gist 02:49
japhb Are there any references on writing (and/or using) a grammar to make it produce decent error messages on failure?
02:53 mr-foobar left
kjk @Juerd, sorry to dump this on you, but here's the script I'm writing that's having the issue with rename. gist.github.com/kjkuan/1f575bb323b...06193548c2 02:53
Juerd kjk: I don't mind but I do feel free to ignore it because I'm almost going to bed :) 02:54
I'll have a quick look though
02:54 atroxaper joined
kjk oh no worries then, thanks for helping 02:54
Juerd It seems that for doesn't propagate sink context? 02:55
I wonder if that's a bug or an obscure feature.
geekosaur I was just thinking that. probably returns the last thing in the block or somethin
then MAIN's magic becomes an edge case
Juerd geekosaur: But the loop is the last thing in MAIN and I'd expect *that* to be sunk...
The same thing without the loop would have thrown the failure 02:56
geekosaur Im not sure I'd expect that. depends on whether MAIN was supposed to inspect the final value to decide perl 6's exit code
in which case that might be an NYI or something with an unfortunate side effect
Juerd I don't think it has to do with MAIN
The same thing happens with a regular named sub
geekosaur ...
02:57 mr-foobar joined
Juerd perl6 -e'sub mv ($a, $b) { for 1 { rename $a, $b } }; my $x = mv "does-not-exist", "meh";' 02:57
Err 02:58
Shouldn't have that assignment obviously :)
Same result without the "my $x ="
geekosaur m: sink [1,2,Failure.new('boo!')]
camelia ( no output )
geekosaur thinkI just golfed it
for returns a list of the final block values. one of those values is a Failure. sinking the list doesn't fire the Failure 02:59
Juerd kjk: A work-around is to add a statement after the rename, like simply "True;" as in the git issue AlexDaniel` linked.
Good night #perl6
kjk k, thanks
geekosaur m: sink [Failure.new('boo!')]
camelia ( no output )
AlexDaniel` “use fatal;” is probably better
m: use fatal; say sink [1,2,Failure.new(‘boo’)]

kjk so is this a bug or just a trap?
AlexDaniel` it's a trap, but maybe we don't have it documented yet 03:00
geekosaur mm. I think for now I say trap, because having sink context force evaluation of a possibly infinite list to trip embedded Failures seems kinda bad
03:00 Sgeo joined

timotimo interesting! let me look closer at that 08:12
oh, the sigspace is not declarative, right? 08:13
the default ws you get, i mean
08:13 ryn1x joined
timotimo so the declarative prefixes of sub and num are the same length, and so a tiebreaker has to decide which gets precedence 08:13
08:15 mr-foobar joined, xtreak joined
timotimo hah, now i get it to fail every time, regardless of which i put first 08:16
08:16 HoboWithAShotgun joined 08:17 cdg joined
wander don't understand declarative prefixes well, but by convert `rule' into `token', it uses longest match 08:18
08:18 cdg_ joined
timotimo doesn't work properly for me 08:20
if i put \s+ in between things and use token, it does work
wander right, i use "2-1" instead 08:21
jnthn rule means to insert <.ws> in place of (non-leading) whitespace. <.ws> is not declarative, unless you override the definition
08:21 cdg left
timotimo yeah, i declared ws to be \s* or \s+ and that didn't help with "rule" 08:21

moritz to first approximation, multi dispatch ignores named params 08:36
timotimo it'd also be nice if something told people to put a link to the github repo page in their commit messages
i find that a gigantic help
TEttinger eh? 08:37
that would be a mess browsing on github
DRY etc.
timotimo you think so?
i find it messy to have to either type the whole url myself or copy-paste and edit parts to get to it
DrForr Could you edit the boilerplate commit message to add a big ol' blinking notice? 08:38
timotimo no, that's the pr message, which is "just" a comment that github has 08:39
i was hoping for the message on the actual commit to have it, which github won't let us suggest anything for i don't think
so if they see it in the pr template, they'll have to go back and amend the commit to include the text

timotimo it's already nicer to have "Add Foo::Bar to ecosystem" compared to "Update META.list"
TEttinger I don't know anything about the perl6 ecosystem. if people need to do this by hand, they won't
timotimo we can do it for them, but that'd mean rebasing and force-pushing, or doing the equivalent of github pull-requests some other way 08:43

timotimo it'd be a good idea to "done" the supplier when all values have been emitted 11:30
also, best to return $p.Supply rather than $p itself

Zoffix Is there a way to somehow signal to the channel or supply that when a value is received it should just close it? Basically, I got a setup like this currently: github.com/zoffixznet/perl6-Reminders#synopsis A react block just recieves values and my object has a marker that signals when all the values were *sent*. But that has a race and the marker triggers end of react if all the stuff is sent before 19:21
previous stuff got received: github.com/zoffixznet/perl6-Remind...m6#L45-L48
One thing I can think of is having a `.close` method on my object that will send some dummy value down the Supply or Channel and the receiver of it can be done based on that, but that's kinda iffy, since in some usecases the user may not want to look for dummy value 19:22
Basically, I need a way to Channel.close or Supply.done but for that to trigger only when all the current values chave been consumed. 19:23
hmm
Zoffix hackety hacks a bit
lizmat El_Che: looking forward to being able to report success 19:24
Zoffix: this feels similar to the issue with iterators signalling that they're done 19:25
create a Mu.new, send that raw and then do an =!= to check if it's done?
Zoffix The user would need to check that tho, no? 19:26
I don't want the user to do that
It'd normally work this way, but I got Promises future-sending values. I think I got it though: add marker to future-done in those cases 19:27
Zoffix compiles and runs
El_Che "Zoffix complies and runs" sounds cooler 19:28

hope that helps :-)
HoboWithAShotgun maybe that's the problem. too much ram, something overflows and perl thinks wrongly about how much memory it has 20:41
but then, they wouldn't repeat microsofts mistakes, would theyß 20:42

ryn1x_ Yeah this is a work computer and unfortunately it is a windows box. Our typical setup is 128-256GB of RAM. 20:44

ryn1x_ :lizmat waiting for a stacktrace now... the repl freezes for a while trying to read in the file... 20:45
lizmat ryn1x_: weird, slurping a 16MB should be less than a second
ryn1x_ :lizmat just un-froze. I am running the repl with the --ll-exception flag and did not get a stacktrace. Just this message again: Unable to allocate an array of 16781312 elements 20:47

lizmat ryn1x_: can you try running it outside of the REPL ? 20:53
ryn1x_ :lizmat ok 1 sec. I am also installing Rakudo Star on another box to try that out too. 20:54
20:55 Guest35881 left
ryn1x_ :lizmat looks like it might be doing the same thing... terminal is waiting... 20:57
lizmat feels to me something weird is going on there. Is the code you run just the slurp() or is there more? 20:58
20:59 nadim joined
ryn1x_ just slurp. I put it in a sub MAIN but I can pull it out to the top level... nothing else in the file 20:59
lizmat to get some metrics: slutping a 16MB file into a scalar takes 1.7 seconds for me, memory usage goes up to about 350 MB 21:04
21:04 natedev left
lizmat *slurping 21:04
jnthn just did slurp with :bin of a 450 MB file
(And it worked out) 21:05
So not sure hwat's going on...16MB is pretty tiny
AlexDaniel` used to slurp and spurt half-G files a lot
ryn1x_ lizmat: it is working now. I put it in a file all alone and it ran instantly. Then added a say $img and it froze forezer. Then changed to say[0] and it printed the first value. Maybe the repl errors because it tries to print the large array after it is slurped?
jnthn Ah, it's probably that
Trying to nicely format it
m: say Buf.new(1,2,3)
camelia Buf:0x<01 02 03>
jnthn Like that
:) 21:06
jnthn afk for a bit
AlexDaniel` if it's the .gist that does that, then it should be smarter
lizmat hmnmm... but a gist should limit to 100 elements 21:07
ryn1x_: are you slurping with :bin ? 21:08
ryn1x_ lizmat: yes.
lizmat hmmm 21:09
nothing comes to mind atm :-(
but then I'm also writing the P6W atm

ZofBot Zoffix, Will remind you on 2017-10-21T18:08:21.578495-04:00 about make recent modules pages on modules.perl6.org, bruh
ryn1x_ Zoffix: I am using 2017.07 22:09
Zoffix ryn1x_: yeah, that doesn't yet have Buf.gist fix. 22:10
(if that's what the problem was about_ 22:11
)
ryn1x_ I tried to reproduce the result on a unix laptop I have here with the same file and it has been paused at the repl for ~45mins now. Even small files, under 1MB take quite a long time to slurp when in the repl.
Zoffix Yeah, it was dog slow 22:12
c 2017.07,HEAD Buf.new(1..1000).gist; say now - INIT now
slurp itself is likely fast, just the gist is slow 22:13
c: 2017.07,HEAD Buf.new(1..1000).gist; say now - INIT now
committable6 Zoffix, ¦2017.07: «0.1359061» ¦HEAD(d6a9eda): «0.0196757»
ryn1x_ I am going home now, but I will check the laptop in the morning and see it actually printed the array after slurping or if it gives me the same "unable to allocate array of x elements" error as the windows box.
Zoffix: I think you are right.. because it slurps instantly in a source file. 22:14
Zoffix ryn1x_: there was a ticket for that; it's possible that got fixed after 2017.07 release
for allocate array on windows
lizmat goes to get some shuteye

perllearner89 Zoffix: Cool. I just figured I would do a little test. Thanks for your help.
AlexDaniel` raschipi: if you're willing to toast yourself, let me know and I'll give you the DB file (so that we can compare previous results with your run)

oh, bedtime for me 23:24

AlexDaniel` what's the right behavior? 23:27
Zoffix AlexDaniel`: deciding that is part of the fix :) TimToady suggested generating a RatStr in those cases (it knows how to behave like a FatRat) and I said I'll try that first. Which is how the bug landed into my private stash :) 23:28

raschipi Should indicate that in the name, I think. Color naming is a huge topic and the HTML version is the least useful of them.

HoboWithAShotgun raschipi: which palette do you consider more "useful"? 23:59
raschipi Well, other usually try to at least represent actual colors. HTML color names ensure they will look different everywhere, instead of looking the same.
