sortiz sammers, usually module's ./bin/* files are installed at $*REPO.next-repo.writeable-path.child('bin') 03:20
03:25 canopus left
dj_goku he sortiz question. you remember helping me with some inet_* c (native call stuff). you think that would be useful for others? I was thinking of creating a module of ones I have created an interface through nativecall. 03:29

ugexe technically only bin wrappers are installed in /bin 03:42
my $curi = CompUnit::Repository.repository-for-name('site'); my $bin = $curi.prefix.child("sources/" ~ $curi.files("bin/xxx", name => $name-of-dist)<files><<bin/xxx>>); # something like this to get the actual bin script 03:45
03:46 kyclark joined
ugexe or my $dist = CompUnit::Repository.repository-for-name('site').resolve(CompUnit::DependencySpecification.new(:short-name("name of dist")).distribution; my $bin = $dist.prefix.child("sources/" ~ $dist.meta<files><bin/xxx>) 03:51
The second one requires a blead version of rakudo though 03:54
03:58 khw left 03:59 canopus left 04:01 obfusk joined
ugexe or if i misunderstand the question: you need to do `rakudobrew rehash` after installing the module with bin/* files 04:03
04:05 canopus joined 04:14 kyclark left 04:18 slobo left 04:20 canopus left
sammers sortiz, ugexe, thanks. `rakudobrew rehash` solved the issue 04:21
04:24 skids left, canopus joined
sammers whenever I run a command in the generated USAGE message includes the full source path in the MAIN examples... is there a way to avoid this? 04:25
I should add, whenever I run a command that is located in ~/.rakudobrew/bin/ 04:26
ugexe no, because otherwise you wouldnt be able to differentiate between 2 scripts of the same name that are both in your PATH 04:31
when you use rakudobrew you essentially have 2 copies of your bin scripts in your PATH (the copy rakudobrew makes, and the copy from your rakudo/install/bin) so you get the full path shown 04:32
sammers it prints out something like this when I run the command "Usage: /home/user/.rakudobrew/moar-2016.06/install/share/perl6/site/resources/55EC986C6963846DFA7B2117603305011CD0103F update <filename>" 04:33
ugexe right
sammers so for now I am just overriding the USAGE message
ugexe that doesnt help for `script --non-existant-option` 04:34
sammers I guess as a user when I run a command available on my $PATH I would't expect to see "/home/user/.rakudobrew/moar-2016.06/install/share/perl6/site/resources/55EC986C6963846DFA7B2117603305011CD0103F", I would expect to see "nameofcommand" instead. 04:35
ugexe the only way to fix it would be (i think) to make rakudobrew spawn the bin script but modify ENV for that process to not have rakudobrew/bin dir in PATH 04:36
but nameofcommand might not run that script
when you do `scriptname` it runs some rakudobrew shim, not your actual script 04:37
sammers when I run rakudobrew rehash, it makes nameofcommand available on PATH
ugexe so the full path needs to be shown
i know what it does
sammers right, but if I run nameofcommand then I want to see nameofcommand in the Usage message output for that command
the long shim doesn't mean anything to me
ugexe that doesnt mean such situations dont exist 04:38
sammers right
they do
but I mean, the normal expectation would be to see nameofcommand
it basically discourages us from using the generated USAGE message 04:39
ugexe the script doesnt know that. the script is launched by a shim
sammers yeah
ugexe no it discourages you from using rakudobrew
sammers yeah, good point..
this is installed via panda 04:40
ugexe if you dont use rakudobrew and instead just add the rakudo install/share/site/bin path to PATH you dont get that
sammers panda install .
ah
ugexe because then there is only a single copy of your bin script, the original. not a shim with the exact same name and the original
04:41 Cabanossi left
ugexe github.com/rakudo/rakudo/blob/3ebf...ain.pm#L73 04:41
you can see how it actually works 04:42
sammers ok, thanks 04:43
ugexe as an example: if i made a script named 'apt-get' the USAGE would be incorrect if it said it was invoked with just `apt-get` 04:44
04:45 BenGoldberg_ left
ugexe because apt-get would invoke the OS package manager, not your bin script 04:45
04:45 Cabanossi joined 04:47 xiaomiao left 04:48 xiaomiao joined
sammers right, but even in that case, the new apt-get runs from ~/.rakudobrew/bin/, but the usage prints out the long shim path. 04:55
ugexe ~/.rakudobrew/bin/ isnt your script, its just a bash or perl script that launches your actual script 04:56
04:57 ufobat joined
ugexe your actual script has no way of knowing this 04:57
sammers right, but "nameofcommand" is the command I run to launch ~/.rakudobrew/bin/nameofscript 04:58
ugexe yes, and your script has no way to know it was launched by a shim
maybe you write your own shim that launches it with `foobar`, would you expect USAGE to know or display this?
sammers ok, so for example, I am using rakudobrew to manage moar and panda because it is easy. 04:59
and I isntall a local module using panda install .
and it makes the nameofscript availabe for use
so is there an alternative setup that could get me the same functionality without using these shim names in usage?
ugexe those arent shim names 05:00
sammers or just override usage?
ugexe those are the actual names of the scripts
sammers ok
yeah, so any better alternative?
ugexe they only show scriptname if NOWHERE earlier in PATH contains a scriptname
sammers just install everything seperately without using rakudobrew?
ugexe which is impossible if you want shims with the same name
sammers I understand why it behaves like this now. that all makes sense. so I want to setup my system so that auto-generated USAGE methods do not use these long names in the output. what is the recommended setup to avoid that behavior? 05:03
ugexe you cant yet
sammers ok, that is fine.
for the time being I will just override USAGE.
keeps things simple
ugexe that won't fix 'scriptname --asfasfasf' though 05:04
where --asfasfasf is invalid option
05:05 canopus left
sammers ok 05:06

psch oh
i honestly don't know what that would mean
same for 'augment' and 'supersede', actually
DrForr They're mentioned in the variable docs. 08:59

09:02 pdcawley joined
psch hmm, still, making sense of an anon variable declaration seems somewhat hard :) 09:03
DrForr The topic 'variable declarators' would seem to imply that you can declare an 'anon $x;' just like you declare 'my $x;', but that's not the case.
psch yes, but it does state NYI

DrForr I haven't looked deeply enough into what the anonymity means, I'd probably agree at that point. 09:10

DrForr I'm just pointing out that 'anon', 'augment' and 'suspend' are in the variable declarator section of doc.perl6.org and probably shouldn't be there if it makes no sense for a variable to be anonymous, and I agree that it doesn't make much sense. 09:11
Though this does mean I can add a whole new section to the test suite, since I'd forgotten that declarations can be applied to sub &c. 09:13

lizmat the only anecdotal story I've heard about long parse times, was from TheDamian, but that seemed to involve very high unicode codepoint values in the source 11:21
Xliff: ^^^ I assume that's not the case with your code ? 11:22
Xliff lizmat: You are correct. There is very little (dare I say non-existant) unicode codepoint values in the code, unless you consider the following: 11:25
github.com/Xliff/p6-XML-LibXML/blo...om.pm#L293
11:26 rindolf joined
lizmat well, that could be it... 11:26
Xliff However I was experiencing high parse times before that method was written, just not to this extent. 11:27
lizmat EFFFF is pretty high, no ?
moritz uhm, I thought this was about literals in the source code
11:27 user9 left
moritz not about regexes matching high codepoints 11:27
lizmat Xliff: if you simplift that token to only the first line, does that change the parse time ? 11:28

Xliff Updated to latest rakudo while I was working on this. 11:31
And parse times are comparable to before update.
And it looks like simplifying the token did not have an effect.

Xliff Thanks for the thought though, lizmat++ 11:38
I've been struggling with compile times for weeks and I am no closer to a solution than when I started.
I am almost wondering if there is something circular in my "use" order that's causing the problem. 11:39
nine Xliff: if there were a circle, you'd either get an error message or it would take forever. 11:40
Xliff And I'm assuming you mean really forever and not just 91 seconds? =) 11:41
nine yes
Xliff Heh.

lizmat Xliff: does RAKUDO_MODULE_DEBUG=1 give any extra timing info ?
nine Well, not really. It would give you another error due to too many processes or full memory
Xliff For those wanting hands on experience, you can check out branch 07dtd from here: github.com/Xliff/p6-XML-LibXML/tree/07dtd 11:42

lizmat: Gives plenty of info, but it's all greek to me. 11:44

OK. 5 minutes are up. Trying again without RAKUDO_MODULE_DEBUG 12:12
That's going to make it a pain to track, though.
lizmat Xliff: is there a reason it's loading Test ? 12:13
Xliff Yes. t/07dtd.t <-- test script
Stage parse : 40.032 # Completes without RAKUDO_MODULE_DEBUG
So there are two issues that I am seeing: 1) long parse times 2) inability to use RAKUDO_MODULE_DEBUG in certain situations due to loop 12:14
lizmat: Do you think loading Test is an issue? 12:15
lizmat no, I was just wondering: I had assumed this was just about doing -Mmodule rather than trying to run it from a test script
Xliff lizmat: Based on my experience, it happens in both situations. 12:16

And how can I fix it?
nine Xliff: I get 3 second stage parse after the first run and 8 seconds stage parse after modification of lib/XML/LibXML.pm 12:53
The first run does indeed take some ~ 50 seconds where it compiles loads of modules. 12:54
Xliff nine: Try modifying lib/XML/LibXML/Node.pm
12:54 rurban left
Xliff That should trigger a recompile of just about everything. 12:54
And that's where you'll see >70 second precompiles.

nine Xliff: we're gonna need more info to help with that 13:37
Xliff nine: What kind of info? 13:38
gfldex moritz: S04 introduces the constant declarator but doesn't say how it's name should look like. I would assume that the general rules for variable identifiers apply and that includes the package part of a name. I can't see how adding the ability to have a fully qualified name would break existing code, so adding it should not cause harm.
moritz Xliff: for example how you call it?
13:39 TeamBlast left
Xliff moritz: github.com/Xliff/p6-XML-LibXML/blo...nt.pm#L412 <- Call made here. 13:39
Class is loaded on Line #11
moritz Xliff: what's in $.extSubset when you get that error? 13:40
Xliff Will check.
13:41 TeamBlast joined
Xliff Odd. I thought the issue was the nativecast, not the value being cast. 13:42
nine Xliff: what exactly is that line supposed to do anyway? Seems to me like nativecast is meant for casting to one of the native types, not user classes. 13:45
Xliff Yes, but the user classes are repr('CStructs') 13:46
s/CStructs/CStruct/
So that should still work.
$.extSubset.^name == "xmlDtd" 13:47
I can't print or dd those values because the structs contain circular refs.
But the point there is to cast the bare struct into it's decendent class.
so xmlDtd goes to XML::LibXML::Dtd 13:48
xmlDtd is low level internal, whereas XML::LibXML::Dtd is what we pass to consuming code.
Prevents circular refs. 13:49
nine Xliff: I can reproduce the error by adding this to rakudo's t/04-nativecall/09-nativecast.t: class Cuter is CUTE { }; is nativecast(Cuter, ReturnStruct()).i, 100, 'casting to CStruct works'; 13:52
CUTE is repr('CStruct') but you cannot nativecast to its subclass 13:53
This however works: class Cuter is CUTE is repr('CStruct') { }; is nativecast(Cuter, ReturnStruct()).i, 100, 'casting to CStruct works';
moritz so maybe the error message should be "Cannot cast to $typename, because its representation does not allow nativecasting"? 13:54

DrForr The main point is being very picky about what gets parsed where, so I can catch errors as early as possible. 15:20
15:20 ugexe joined
DrForr I *really* want to create a with-hash-keys(..) { } macro, but if I do that I'll never get around to finishing the module :) 15:21
pmurias DrForr: Perl6::Tidy itself is not part of the gist? 15:22
ugexe sub foo(% (:$key1, :$key2)) { } is already easy enough no?
DrForr It's just a thin shell that invokes Root.new() on the parsed object, it's pretty trivial. 15:23
ugexe: Good point, though I might need to go farther than that.
15:23 mohae joined
DrForr pmurias: Updaetd with the core method, Perl6::Tidy::Root.new(...) does essentially the same thing as the other classes, its new() method tears down the hash or list into a Perl6-space object. 15:26
It just runs the core parsegrammar method with the parseactions methods, it needs $*LINEPOSCACHE because apparently a few methods need it.
pmurias DrForr: what's the benefit of having a Perl 6 class for every grammar rule? 15:30
DrForr This lets Perl 6 users be able to walk the parse tree of a grammar without needing to learn NQP? 15:31
15:31 dvinciguerra joined
DrForr And my plan isn't necessarily 1:1 rule:class. 15:31
In fact it can't be in most cases. 15:32
15:33 zakharyas joined
pmurias can't because of <.foo> rules or it shouldn't be? 15:33
DrForr For instance there's no need for EClass to exist in the final parse tree, because the only thing the Perl 6 user wants to know is "What is the number in this argument?" They don't need to know the individual scale...
15:35 rindolf left
DrForr I'm not intending to mimick the exact grammar, it should be possible for users to say 'say ArgList.Str' and get back a stringified version of the arguments without worrying about what class each one of them is. 15:37

parabolize hoelzro, also the ww adverb: qww, qqww and Q:ww
lucasb_ its definition is: has-phasers() { nqp::attrinited(self,Block,'$!phasers') }

gfldex it would also impact performance quite a bit

lucasb_ gfldex: what? the p6bool op?
gfldex but then, subclassing Block would be tricky
expect has-phasers to be called a lot 16:30

fsavigny: what IRC client are you using?
fsavigny Riece. It 20:54
Riece. It is an Emacs package.
Is there an upper limit to the number of characters, perhaps? 20:55
gfldex there is and a proper IRC client will send as much as will fit
parabolize there is but it usually gets split by the client
fsavigny: you could try ERC
its in emacs by default 20:56
AlexDaniel yeah. No problems with ERC at all
fsavigny OK, thanks! I'll switch to ERC and retry. Might take a little while ... Thanks very much! 20:57

geekosaur pastebin sites are also helpful. although a large complex question may be better suited for a mailing list
fsavigny I once wrote an XML/SGML converter, which executes stored Perl code when a certain event happens.
That converter is written in Perl 5 and uses eval to execute this Perl code. 21:02
I am wondering if this is still a feasible method in Perl 6, as eval seems rather deprecated.
lizmat it's called EVAL nowadays 21:03
but having said that, perhaps you'd want to store precompiled code and execute that on demand
that would be *way* faster, if you can get that to work, though 21:04
you would be pretty bleeding edge then
21:04 canopus joined 21:06 mcmillhj left 21:07 wamba left
fsavigny But how would one do that in Perl 6: Store precompiled code? 21:07
My Perl 5 solution simply reads in Perl code as if it were a text file. 21:09
And then stores the code strings in a moderately complex hash structure.
gfldex fsavigny: you write the Perl 6 code into a file that will look like a module. Then precompile and load it. Let me find you a link. 21:11
fsavigny which stores the code according to element name and event (i.e. open, close etc)
geekosaur seems like a custom CompUnitRepo might be a thing here too? 21:12
21:12 adu joined
gfldex github.com/gfldex/pod-to-bigpage/b...age.p6#L63 21:12
you have to decent into nqp-land to precompile and load at runtime 21:13
21:13 skids left
fsavigny And when the converter knows that eg element "HEADER" has opened, it finds the code for the opening of element HEADER 21:13
and executes that using eval.
But to make that clear: Precompiling (or speed, for that matter) is not that crucial to me. 21:14
geekosaur, what's CompUnitRepo? 21:15
gfldex m: use MONKEY-SEE-NO-EVAL; my &f = EVAL('sub f(){ say "oi‽" }'); f();
camelia rakudo-moar 371b93: OUTPUT«oi‽␤»
fsavigny glfdex, that looks quite exactly like the solution I used in Perl 5 ... 21:16
21:16 adu left
geekosaur it's the perl 6 class that manages compiled code. I see gfldex suggested some nqp code needed, but this strikes me as something that could be wrapped into a CUR subclass and made available at perl6 level... 21:16
21:17 adu joined
fsavigny ... but isn't that sort of deprecated in Perl 6 (the EVAL thing, I mean)? 21:17
gfldex why would it be deprecated?
fsavigny Because of the MONKEY-SEE-NO-EVAL ... 21:18
You know that the monkey covers its eyes. Does not want to be responsible, probably ...
lizmat Perl 6 just wants to make sure you know what you're doing
geekosaur not so much deprecated as marked as dangerous 21:19
so you need to include a "I know what I'm doing"
lizmat I mean, compiling source code from untrusted sources is asking for problems, generally
gfldex also, you may anger the optimiser 21:20
lizmat fsavigny: have you considered putting code blocks in a hash?
gfldex didn't there be a trait called 'is deprecated'?
21:20 adu left
lizmat m: my %h = HEADER => { say "header" }; %h<a>() 21:20
camelia rakudo-moar 371b93: OUTPUT«Cannot find method 'Any' on object of type List␤ in block <unit> at <tmp> line 1␤␤»
lizmat m: my %h = HEADER => { say "header" }; %h<HEADER>() 21:21
camelia rakudo-moar 371b93: OUTPUT«header␤»
fsavigny Putting them in a hash is actually what the (p5-based) converter does internally.
That would mean I would have to directly write the instructions into a hash. 21:22
gfldex there is very little that you coudn't do with a closure
fsavigny But apart from that, would that change anything about having to eval the code?
21:23 dvinciguerra left
fsavigny Also, my reading-in solution had the nice sidekick that you could automatically add code before and after it 21:23
gfldex i can't see what you actually need EVAL for
there where cases where eval saved you plenty of typing in perl 5. That should not be a problem in Perl 6 tho. 21:24
fsavigny Hmm, gfldex, so do you mean using anonymous subs as the values of the hash, maybe?
gfldex yes, and with some functional programming sprinkled on top 21:25
lizmat m: sub a() { say "a" }; &a.wrap( { say "before"; callsame; say "after" } ); a # fsavigny 21:27
camelia rakudo-moar 371b93: OUTPUT«before␤a␤after␤»
gfldex m: sub factory(&before, &after){ return sub { before(); say 'oi‽'; after(); } }; my %h = one => factory({say('hello')}, {say('baby')}); %h<one>(); 21:28
camelia rakudo-moar 371b93: OUTPUT«hello␤oi‽␤baby␤»
literal so, there's IO::Path.extension ... is there no corresponding method to get the part of the filename without the extension? 21:29
fsavigny callsame looks interesting, thank you! I think I will evaluate that before continuing to ask ... 21:30
literal or at least something nicer than $foo.match(/^(<-[.]>+)/)[0] 21:32
perlpilot literal: isn't that .path ? 21:34
or, I guess perhaps .path ~ .basename
fsavigny Thanks to everybody for your patience, and have a nice evening!
21:34 fsavigny left
gfldex .basename.split('.').reverse[1]; 21:35
literal perlpilot: no, basename includes the extension
lizmat I think I had something for that in the newio branch :-(
gfldex you need the reverse[1] for '.foo'
actually that will fail for 'file.foo.bar' 21:36
literal yes 21:37
like bla.tar.gz
gfldex m: 'file.foo.bar'.split('.').reverse.rest.reverse.say
camelia rakudo-moar 371b93: OUTPUT«Method 'rest' not found for invocant of class 'List'␤ in block <unit> at <tmp> line 1␤␤»
lizmat perhaps .basename.substr(0,*-(.extension.chars + 1))
perlpilot yuck 21:38
lizmat
.oO( yuck )
perlpilot heh
literal m: say 'file.foo.bar'.comb(/<-[.]>+/, 1) 21:39
camelia rakudo-moar 371b93: OUTPUT«(file)␤»
perlpilot lizmat: maybe add .fileparse like p5's File::Basename ? 21:41
lizmat perlpilot: perhaps, but I'm pretty burnt out on IO stuff
literal it's worth noting that IO::Path.extension actually doesn't return the full extension currently (i.e. only ".gz" in "foo.tar.gz") 21:42
gfldex the docs got filenames where the . is actually part of the filename 21:43
Ulti perf looking good gist.github.com/MattOates/c2e19950f46d1a1c241a
gfldex so it's not that easy to decide
lizmat Ulti: so roughly 3x as fast, if I read that correctly ? 21:44
since Sept 2015 ? 21:45
perlpilot gfldex: that's why I was thinking about fileparse actually. You can specify the suffixes you care about.
Ulti lizmat well not from Tim King's original! he had 2s for something that is now 0.05s so thats 40x faster 21:46
granted my CPU is more modern than his
2013-09 to now 40x faster on something numeric with lots of array pushing 21:47
I didnt write this up last time because I contacted Tim to maybe update his own blog but I heard nothing back 21:48
given if you search Perl 6 and speed his is the first blog you come across its worth putting something in the world that this isn't still true 21:49
gfldex m: say so 'file.tar.gz'.ends-with(any(<.tar.gz .tar.xz>));
