Zoffix | andreoss: looks good, though the check for `stdin().t()` can probably be moved into `elsif !@a`, so we only do it once, something like `elsif !@a { $result := stdin().t() ?? self.interactive(|%adverbs) !! self.evalfiles('-', |%adverbs) }` | 00:21 | |

||
firefish5000 | I expected apple to be printed both times. What am I missing? | ||
From my current understanding, The first one should match 'ap' successfully. And then check ['apples' which fails, then 'apple' which should succeed]. Then 'ap' | 'apple' should be compared and the longest match 'apple' should be returned no? | 05:23 | ||

firefish5000 | I think these still may be separate issues. Seems to me that the longest alternation, in your case, is preferring ones with the earliest match in the sting. This may be intended, depending on how you interpret #5 on design.perl6.org/S05.html#Overview | 06:22 | |
06:23
sena_kun joined
|
|||
firefish5000 | That is, since 'a', the first letter matched, it seems it is ignoring all matches after it that don't also match the first letter. Even if it is longer | 06:23 | |
06:24
mcmillhj joined
|
|||
piojo | firefish5000: I don't think #5 should have any effect, since that list is based on tie breaking--it should stop at #2 based on longest matched text | 06:26 | |
06:29
mcmillhj left
06:30
mcmillhj joined
|
|||
firefish5000 | True, but then again, when looking at a regex. I normally expect it to start at the first match. Consider the same regex with a quantifier (as it is in the bug). If it actually preferred the longest match over earliest matching char, then quantified regexes would have a lot more backtracking to do. | 06:30 | |
piojo, I think that that this is just a case of insufficient documentation, or perhaps we skipped something in the docs. But it conforms to my limited understanding of regexes | 06:32 | ||

piojo | firefish5000: how are you reading it? To me, it looks like the way you sort a list of tuples: | 06:35 | |
$a[0] ne $b[0] ?? $a[0] <=> $b[0] !! $a[1] ne $b[1] ?? $a[1] <=> $b[1] !! ... | 06:36 | ||
pardon my mix of perl5 and 6 syntax | |||
tie breaking logic will stop at the first obvious non-tie. | |||

El_Che | Slightly related, I am under the impression that discussions about Perl 6 tend to drift to utf8 coolness and less about the features many people care about (concurrency, sane OO, builtin kitchensink) | ||
I have convinced some people to try rakudo because of the features above. | 11:52 | ||

Zoffix | El_Che: I think it's just the easiest thing to talk about as well as the most visibile (you don't even need to understand the code and you can comment). I know when I just started with Rakudo, custom Unicode ops is basically the only thing I talked about. | 12:04 | |
AlexDaniel | El_Che: people naturally don't want to spend time on learning something. It is much easier to nitpick a feature that makes no sense to you and reject the whole language instead of looking deeper. Most reddit commentors are not Evan Miller. The weekly itself discussed the feature in more detail (even provided an example on how this feature can be used), it's the commentors who tunnel-visioned on the non-ascii symbol | 12:05 | |
Zoffix | And perhaps a lot of the commenters on those threads simply aren't familiar with atomicity or Rakudo to comment on anything else other than give opinion on these crazy new emoji operators | ||

sena_kun | The pipeline is not dynamic, to be precise. let me explain this thing a bit... | 12:22 | |
raschipi | I'm familiar with how the http/2 over TLS situation looks like. | ||
sena_kun | basically, if https is present, VersionSelector github.com/croservices/cro-http/bl...lector.pm6 is used. It checks for alpn and if we're here: we emit to one supply, otherwise - to another. So there is basically a graph of supplies. | 12:23 | |

sena_kun | raschipi, no problem. I will be glad to provide explanations for almost everything, except for future project's decisions(tehse things up to jnthn) and some rare pieces I didn't touch. | ||
*these | |||
Zoffix | sumdoc: get() from WWW.pm6 module fetches the HTML code (is that what you mean by "read"?) and then DOM::Tiny parses it and using CSS selector, I tell it to print all text from a specific element | ||
census: if you look at the page's source there's <meta name="ncbi_resultcount" value="53"> or something like that, in <head>. `meta[name="ncbi_resultcount"]` is a CSS selector for that element and DOM::Tiny uses CSS selector to retrieve content of specific elements | 12:28 | ||
sumdoc | This gives me the desired output. I was wondering if I can do it from within core P6 Zoffix | ||
use LWP::Simple; my $html = LWP::Simple.new.get("www.nytimes.com/2017/08/28/us/hous...-region"); say $html; | |||

sumdoc | Zoffix Yes | ||

census | Zoffix thank yoyu for your continued help. when i used to do this in perl5, i never had the fortunate of having something so straight forward like you found through the page source. i always did a regex type trick | 12:39 | |
AlexDaniel | FWIW, I'm using perl6 for everything nowadays. One of the relatively big things I have here is web scraping, all of which is currently shelved because Gumbo segfaults with current rakudo | 12:41 | |
Zoffix | census: think outside the box. There's a "download CSV" link. Look at the link: patents.google.com/xhr/query?url=q...nload=true It got your quiery in it. So that means you likely can directly construct links to CSV files. Download one of them, look at its structure: it got result-per-row + 2 rows for headings. That means to get | 12:42 | |
AlexDaniel | one of projects is using python-gumbo through Inline::Python, which I don't like but at least it can parse 100 pages without segfaulting | ||
Zoffix | your results all you need to do is make a URL to csv to fetch the CSV data then parse CSV and subtract 2 from total row count to get number of results | ||
census: perl6 -MWWW -MText::CSV -MURI::Encode -e 'my $term = uri_encode "Babesiosis"; "temp".IO.spurt: get "patents.google.com/xhr/query?url=q...oad=true"; say csv(:in<temp>).elems - 2' | |||
172 | |||

Instead I'm getting "Use of uninitialized value % of type Any in string context.". :S | |||
s/works then/works when/ | 12:45 | ||
Zoffix | Some cases where I choose, say Perl over Rakudo, is mostly due to lack of Rakudo libraries that I like, something polished like Mojo::Pg or Mojolicious.

Zoffix: did you consider reporting the stuff that doesn't work in Inline::Perl5? ;) | 13:01 | ||
Zoffix | perlpilot: or more specifically, the three times I tried to use it it didn't work. Awhile back I tried to use Mojolicious and struggled figuring out how to access data in templates. When I tried to use WWW::Mechanize, I saw no obvious way to give its methods Perl regex objects. When I tried to use Spreadsheet::XLSX, I could access its attributes, because it provides them by directly offering the blessed hash, | 13:03 | |
rather than via methods. | |||
perlpilot: so I don't know... either I'm very unlucky or people overhype the usefulness of Inline::Perl5 | 13:04 | ||

Zoffix | pmurias: nope | ||
*couldn't access its attributes | 13:06 | ||
perlpilot | Zoffix: fair enough. though, one of the first modules I used with Inline::Perl5 was Spreadsheet::XLSX and I don't remember having any problems. But I just looked for the code and can't find it so ... recent experience trumps vague memories of code that may no longer exist :) | 13:07 | |

sumdoc | I want to substitute one word with another word. How to do that? Should I open in :append mode? Example: my $fh = open("file.txt",:a); Now how to substitute? | 14:48 | |
When working with a file. | |||
timotimo | that will only work if both words have the same length | 14:49 | |
like, in general | |||
i haven't actually tried to do this at all for the longest time, but i think all you need to do is use append mode so it doesn't truncate the file, seek to the position you want, then make sure to write exactly the same amount of bytes everywhere | 14:51 | ||
i.e. it'd be a good idea to only do this in :bin mode | |||

Ven`` | El_Che: I know nothing about how Dancer compares to Sinatra. I just know Bailador doesn't seem to do middlewares like I expect it to, and has hacks like `noprefix` | 15:05 | |
El_Che | Bailador had some nasty locking issues after a X number of concurrent sessions (although high: 200?) | ||
Does cro has a similar issue? | |||
sena_kun | it is yet to be tested under such load, I guess. | 15:06 | |
and as for now things are unoptimized performance-wise. | 15:07 | ||
El_Che | That was actually not a bailador issue, but the underlaying plack implementation iirc | ||
ufobat | Ven``, what is `noprefix` ? | 15:08 | |

Ven`` | ufobat: github.com/Bailador/Bailador/commi...9e6a3a4446 | 15:08 | |
raschipi | why ".say for" instead of ".join("\n").say ? | ||
ufobat | Ven``, and bailador can "return" a p6w app, which is psgi, so you can wrap middlewares around it | 15:09 | |
Ulti | mattoates.co.uk/files/perl6/jupyter...t_test.png \o/ looks like ZeroMQ needs to see something special in the Kernel protocol to actually render the SVG as an image :( | ||

jonas1 left
|
|||
ufobat | if you call my $psgi-app = baile('p6w'), it returns an app instead of running it on a server like http::tiny | 15:09 | |
perlpilot | sumdoc: also, I wouldn't mention split("") in that last example unless you also explain why there's an extra element at the front. | ||
sumdoc | raschipi Points noted | ||
raschipi | sumdoc: "$string.comb(/ \w /);" and "$string.comb;" do different things on strings with whitespace. I'm not making any points, I'm just asking. | 15:10 | |
But I do think ".say for" is more difficult to understand than ".join('\n').say" | 15:12 | ||
Ulti | $string.words however does the same | ||
Ven`` | ufobat: that's not how middlewares are done on express, where you can mount apps on apps, middlewares around single routes or prefixes, etc | ||
ufobat | you can't mount apps inside of bailador, right, but you can mount a bailador app somewhere | 15:14 | |
it's psgi'ish | |||
Ven`` | it just comes down to what i'm used to do with express | 15:15 | |
being able to mount app just inside a middleware doesn't interest me | |||
Ulti | Zoffix: thanks sorry I missed it ;_; | ||
ufobat | in psgi you mount apps in an app of its own, and you can wrap middlewars around that | 15:18 | |
metacpan.org/pod/Plack::Builder <- thats perl5 more or less the "same idea" | 15:19 | ||

mst | Ven``: ah, it looks like currently both Cro and Bailador are in the "reinvent ALL the wheels" phase so there's no concept of middlewares or other such reusable building blocks yet | 15:29 | |

well, not yet | |||
Ven`` | mst: the talk about Cro shows pretty nice examples of middlewares, but again, since it depends on signature introspection, I think you can't wrap any function and return a new one | ||

I... | 15:35 | |
...can create two similar files in its configurations. If one file thats being written into by logger.c with syslog in asterisk is opened in perl6 does that also pose similar access sharing problems. | |||

kannan | perlpilot : i am brand new to perl6 and to programming itself. just trying it academically. the problem is already solved by good programmer, with a source code patch in asterisk :) . i can do the needful inside the IO::Tailfile react{block itself, but i thought it was better this was so the tail emulation does not miss any security events... in other words i do not know how fast it will... | 15:47 | |
...execute . i do not know any way to test that also , i guess write anoither program to generate logs at super speeds.. | |||
census | Zoffix I just downloaded and installed strawberry Perl and am having the same error message. should i run it from the cmd still or from the Strawberry Perl client? | ||
raschipi | census: did you close and reopen cmd? | 15:48 | |

Zoffix | sumdoc++ great tutorial! Note .match('is') could be written as .contains('is') which is likely faster too. Also, .split('') and .comb(/\w/) are different things (split will add empty strings at start and end, unless :skip-empty named param is given as well as include non \w chars, while .comb would give only \w; to split string on characters, you can use .comb without any args. P.S.: | 15:52 | |
$string.words.lc.unique.elems doesn't work because .lc combines the words back into a string, you can use hyper operator » to call it on each element: $string.words».lc.unique.elems | |||
sumdoc: I actually learned something: .tc doesn't touch other letters in the string and I thought it did :) Now I remember we have .wordcase for that :) | |||

census | pastebin.com/WJASWPHN | ||
Zoffix | census: and now the OUT_FILE.spurt: :append, "$term,$year,$results-num\n"; line needs to become $fh.spurt: :append, "$term,$year,$results-num\n"; so you write to the filehandle instead of the OUT_FILE (functionally, it won't make much difference really, but at least you're not opening the file on each iteration) | 16:28 | |
census: also, stick $fh.close; after the loop | |||
To close the handle and write everything that's in a buffer (that I don't think we use yet by default) out | |||
census | yes that makes sense because in perl5 i had to close it too | 16:29 | |
Zoffix | Do you? I thought .close would .flush for you and .close is done on scope leave | ||
In Perl, I mean. In Rakudo it doesn't | |||
census: if you look on your filesystem, you'll now find two files: results.txt and output.txt | 16:30 | ||
census | yea in perl5 i had to close the file name | ||
Zoffix | One has output the other doesn't | ||

kannan | ok, specific to my needs, instead of trying to emulate tail -f and reacting to a log file entry, i should write a listener to a socket where Asterisk core writes all the security events. Probably like this -> asterisk -> security event -> perl6-listener -> spawn a separate child script to do the reaction. | 18:40 | |
this looks like a correct solution, better than patching asterisk logger source code even. | 18:41 | ||

that said, expect more stupid comments from me as I'm trying to push around some of the older tickets | |||

BooK | oh, come on: my $split := nqp::split("=",$arg); | 22:08 | |
(and in my above example, I obviously meant --arg=klonk) | 22:09 | ||
I actually don't understand the code around that, so maybe I should work on that first :-) | 22:11 | ||
but, if I try to work my way to a patch to support --arg klonk in addition to --arg=klonk, would someone review it? | 22:12 | ||
or is there already a good reason not to support that? | |||

Skarsnik | hm | 22:12 | |
how to tell not to take a args? | 22:13 | ||
AlexDaniel | BooK: yes, that would be great | 22:14 | |
Skarsnik | like : cmd --args=foo file.txt and cmd --args foo file.txt | ||
AlexDaniel | BooK: not sure if I'll be able to review it, but I'm definitely interested | ||

BooK | AlexDaniel: sure thing | ||
Skarsnik | +force | ||
to distinc Bool vs no Bool | |||
AlexDaniel | BooK: note that there are many things about arg handling that are less than awesome. It's simply that we had no MAIN hero yet. | 22:16 | |
Skarsnik | maybe it written in the spec why? | ||

AlexDaniel | now that I think about it, what software supports “--foo 42” style? | 22:19 | |

BooK | ipatrol: thanks | 22:59 | |
ipatrol | BooK: keep in mind that "Perl6" is itself a language, not a program, and therefore, strictly speaking, cannot have bugs. Rakudo, which is a Perl6 interpreter, on the other hand, can have bugs. | ||

TEttinger | languages can have bugs. they could have conflicts in the specification, for example | 23:01 | |
BooK | what TEttinger said :-) | ||
ipatrol | TEttinger: I'd call those "flaws" or "defects" as opposed to bugs | ||
BooK | so the "perl6" queue in rt is for rakudo? | ||

23:03 | |
ipatrol | BooK: A bug is a behavior of a computer program which is contrary to what is expected. Since the Perl6 language defines what "expected" means for Rakudo, the only bugs are behaviors of Rakudo that do not match the Perl6 design documents. | 23:04 | |
[Coke] | BooK: yes, rt perl6 queue is rakudo | ||
BooK | anyways, I was just trying to figure out how to move forward with my disappointement about MAIN's handling of options | ||
23:04
Kyo91_ joined
|

BooK | I first looked at the code hoping I'd be able to produce a patch, but then wondered if my expecations were in line with the spec, so I thought what about a bug report | 23:05 | |

BooK | I also eyed the roast test suite looking for tests for MAIN, but didn't find many of them (some of them pointed to the RT queue, this is actually how I found/remembered it) | 23:06 | |
I'm basically a confused newbie :-) | |||
[Coke] | so, roast is really the spec - the SYN is a historical document (and I think there was a lot of spec ulative stuff that went in there about options processing which didn't end up getting adopted.) | 23:07 | |
BooK | and since that spec is a program, it can have bugs ;-) | 23:08 | |
[Coke]: more seriously, does that mean any untested behaviour is underspeced? | |||
23:08
pmurias left
|

BooK | underspecified, sorry | 23:08 | |
ipatrol | BooK: in theory, yes | 23:09 | |
m: my $patt = /spam|camel|butterfly/; 'camelfly spam' ~~ /$patt/ and say ~$/; | |||
camelia | camel | ||
BooK | but there is some text somewhere too? I mean code is great, and certainly less ambiguous that prose, but prose has its benefits too | 23:11 | |
AlexDaniel | BooK: there are some historical documents on design.perl6.org/, but most of them are becoming outdated | 23:14 | |
BooK | right, but that's not the right kind of prose :-) | ||
AlexDaniel | well, there's some prose on docs.perl6.org/ :) | ||
still not the right one :P | 23:15 | ||
BooK | heh | ||
ipatrol | Besides those two, there really isn't anything. If they're outdated or incomplete, that's something that needs to be fixed, but that requires manpower. | ||
AlexDaniel | and we'd much rather have this manpower writing tests or fixing bugs :) | 23:16 | |

AlexDaniel | it's less than awesome, but that's how it is | 23:16 | |

BooK | Allow both = and space before argument of double-dash args | 23:17 | |
which is definitely what I wanted | |||
so at least now I know a patch in this direction would get some attention | |||
I just need to learn enough Perl6 to produce it :-) | |||
ipatrol | AlexDaniel: however, I would warn not to neglect the documentation either | 23:19 | |

ipatrol | We'll never get any traction if no one can figure out how to use the blasted thing :-) | 23:19 | |

firefish5000 | Wow, the IRC conversation linked in that ticket took a surprising twist. Seems like some familiar developers were against adding the standard --arg val(s?) syntax, for a variety of reasons. I personalty have been parsing ARGS myself for more complex programs anyways (I don't like dashes, and only include them for --help -h) | 23:46 | |

BooK | firefish5000: it feels like some of the conversation there is about how it's too hard to implement | 23:51 | |
23:51
mcmillhj joined
|
|||
ipatrol | BooK: it should be implemented since it's part of the POSIX standard | 23:52 | |
Either in-language, or as a stdlib | |||
firefish5000 | BooK, rather, hard to implement without adding ambiguity they believe doesn't currently exist. | 23:53 | |
teatime | are long options even in posix | 23:54 | |
ipatrol | teatime: come to think of it, they might not be. could be a GNU extension | 23:55 | |
teatime | it is. | ||
geekosaur | long options are not in posix | 23:56 | |
23:57
mcmillhj left
|

ipatrol | geekosaur: then they should be implemented as a stdlib like Python does, if the developers feel there is no good way to implement them using regular MAIN signatures | 23:57 | |
BooK | irclog.perlgeek.de/perl6/2011-10-17#i_4578793 # many many programs have different CLI behaviour, so users have had to learn how their tools work for a long time | ||
I think VMS did option parsing with the same lib for every program, but that's definitely not the case with unix | 23:58 | ||
just think about tar, dd (whose options are in fact a reference to some other older program with crazy options)... | |||
ipatrol | BooK: I heard dd's syntax was originally meant as a joke | 23:59 | |
BooK | ipatrol: yeah I read that too | ||
ipatrol | why no one has ever implemented at the very least an alternative syntax is beyond me |
