stanrifkin | how can i flush or read EOF after prompt call? i've got a loop with "next unless $line"; after a prompt which works. But when i input a EOF the input buffer seems not to be flushed and i've got an infinite loop. | 12:23 | |
to be clear: loop { my $line = prompt "input"; next unless $line; ... } | 12:26 | ||
when i enter ctrl-d -> endless loop | 12:27 | ||
lizmat | and what about "next without $line" ? | 12:34 | |
12:34
squashable6 left
|
|||
stanrifkin | same behavior | 12:37 | |
MasterDuke | or something like `next unless $line or $*IN.eof`? | 12:40 | |
stanrifkin | same with "uninitialized value" message now | 12:43 | |
i tried it with normal perl | |||
there it works | |||
i mean i want a simple input loop which can handle EOF | 12:45 | ||
lizmat | last without $line ? | ||
stanrifkin | lizmat: yes tried that. does also endless prompt loop | 12:46 | |
lizmat | loop { last without prompt } | ||
stops with ctrl-d for me | |||
are you on windows by any chance ? | |||
stanrifkin | lizmat: moment... | ||
lizmat | loop { with prompt() { .say } else { last } } | 12:47 | |

stanrifkin | lizmat: somewhat i need both now. last without and next unless line | 12:49 | |

stanrifkin | lizmat: that's ok. i get an runtime type error | 12:55 | |
lizmat | that's not very user friendly :-) | ||
stanrifkin | lizmat: i am playing around | ||

MasterDuke | codesections: re stackoverflow.com/questions/699190...ngle-list, wouldn't making print_lists's signature `**@input` also be a solution? | 17:02 | |

lizmat | [Coke]: could you make a doc issue for that ? | 17:15 | |
MasterDuke | yeah, solution was the wrong word/idea. more like something to point out as relevant | ||
codesections | I don't think we need a ™ everywhere, though | 17:16 | |
[Coke] | github.com/Raku/doc/issues/3982 | 17:17 | |
codesections: I'm complaining it's inconsistent, not missing. :) | |||
if there's a method to the usage there, I dont see it. | |||
codesections | from a legal perspective, I think we're fine (not legal advice, etc.) – but yeah, visually it's odd/worth fixing :) | ||

that looks like it went fro 1.41 to 1.14 , and from 14.99 to 6.24 ?? for ip5xs ?? | 19:55 | ||

MasterDuke | i think that's about what nine was expecting | ||
lizmat | 2.4x as fast nine !!! | ||
[Coke] | lizmat: that URL is searching for text - looks like I can search for the nick 'lizmat' but not '[Tux]' | 19:59 | |
[Coke] is also empty, Geth has results. Guessing the []'s are being treated specially somehow. | |||
MasterDuke | i think it treats the string as a regex, what if you \ the []? | 20:00 | |
[Coke] | \[Tux\] also empty | 20:02 | |
his nick is [Tux], but the hits include "Tux is now known as |Tux|"" | 20:03 | ||
will open a ticket. | |||

camelia | 5===SORRY!5=== Error while compiling <tmp> "without" does not take "else", please rewrite using "with" at <tmp>:1 ------> 3my $a; without $a { say 'Unset' } else7⏏5 { 'Set' |
||
codesections | m: say "\t$?TABSTOP" | 20:41 | |
camelia | 8 | ||
codesections | since $?TABSTOP is marked as compile-time, does that mean that expressions like ^^^ might print with a different number of spaces? | 20:42 | |
or is it "compile time" in some sort of nested way that means it still has the correct value? | |||
lizmat | good question | 20:43 | |
the current implementation is pretty straightforward in the setting: | |||
my constant $?TABSTOP = 8; | |||
m: my constant $?TABSTOP = 4; | 20:44 | ||
camelia | 5===SORRY!5=== Error while compiling <tmp> Constants with a '?' twigil not yet implemented. Sorry. at <tmp>:1 ------> 3my constant $?TABSTOP = 47⏏5; |

lizmat | and there's no way to override that at | ||
m | |||
codesections | interesting, thanks. | ||

Xliff | LOL... | 21:06 | |
That doesn't affect $?TABSTOP though, which I am assuming is the default expansion for '\t'? | |||

Nemokosch | yesterday I posted something in the <#538420565980086273> channel on discord, long story short, there is something weird when using junctions to construct paths | 23:24 | |
I did a check essentially like $object-path.extension('cpp'|'c'|'pcc') ~~ :f | 23:25 | ||
and sometimes, under pretty random conditions (e.g this code has run for many files, I ran `git commit` from the script), it threw a warning that during the DESTROY phase, an unhandled exception happened for a .f method call | 23:26 | ||
MasterDuke | Nemokosch: there's currently some debate about whether to disallow junctions on the left-hand side of a smartmatch. i'd suggest trying to rework it so the junction is on the right if possible and see if that's better | ||
ah, though the unhandled exception business is probably a bug | 23:27 | ||
Nemokosch | and it would tell me about paths that actually don't exist but could have been tested | ||
but yeah I didn't even call .f so I couldn't even catch it 😄 | 23:28 | ||
23:28
vrurg_ left,
vrurg joined
|
|||
MasterDuke | well, `~~ :f` is actually calling .f under the hood | 23:29 | |
Nemokosch | so are left-hand side junctions known to be troublesome already? | ||
MasterDuke | how much do you want to read? github.com/Raku/problem-solving/issues/297 | 23:30 | |
Nemokosch | uh-oh | ||
I mean the syntax itself looks neat but today I surely suspected the problem was related to it... | |||
because I had to extend the code in a way that uses nested loops anyway | |||
and bang, no more suspicious warnings | |||
MasterDuke | i would guess that the problem you're running into is not necessarily because a junction is on the left, but probably just junction-related in general, but that's just a guess | 23:31 | |
do you have a golf so i can try to repro it? | 23:32 | ||
23:37

|||
Nemokosch | what is a golf when not that Tiger Woods sport? | 23:40 | |

Sgeo joined
|
|||
MasterDuke | short(est) code that demonstrates the problem | 23:41 | |
from code golf, solving a problem in the fewest characters | 23:42 | ||
but no worries, i have something that does get those unhandled failures | |||
Nemokosch | oh nice 😄 | 23:43 | |
MasterDuke | so yeah, the fact that you're using a junction is what's causing them, though not necessarily because it's on the left (i think) | 23:48 | |
.f creates a Failure if the file doesn't exist | 23:49 | ||
Nemokosch | I was just wondering whether this is known/expected behavior as I got more suspicious about the fundamental cause | ||
MasterDuke | which is normally handled by something like `if $file.f`, i.e., the if puts it in boolean "context" and the Failure evaluates to False | 23:50 | |
Nemokosch | I can very much sympathise with vrurg's takes under that issue fwiw | ||
MasterDuke | but the junction means you get multiple Failures, (at least some of) which aren't being handled | 23:52 | |
Nemokosch | especially with the point that if one wants faster `switch`, maybe it shouldn't be based on a flexible but slow operation - rather than making that operation less flexible and faster universally... | ||
MasterDuke | i go back and forth with each new comment | ||
Nemokosch | oh okay, it makes some sense | ||
the funny thing about this junction smartmatching is that it doesn't seem very deterministic | 23:53 | ||
so for example when I made the git commit call in the meantime, it always threw failures | |||
but sometimes it also threw without |
