Xliff No. It can exist in a module. 00:00
It can exist anywhere, really, but it's better in a module.
It sorta loses its usefulness in program code, since it occurs after compile-time but before precomp.
Scripts are always compiled, so....

tbrowder so, how about this: global var exported vi 00:33
*via a local module. then, in the program script, run BEGIN (or INIT?) the 00:35
*to calculate its value.

Xliff Um. 00:46
Why not in the local module?
If you are going to do this in the script, INIT makes more sense.
tbrowder: Do you have some code? 00:47
tbrowder no yet, its a wip for a PR for Documentable and i haven't pushed any code to my fork yet. 00:49
Xliff Can you coble together a quick example of what you are trying to do?
tbrowder i'll try the module first and see how that goes.

guifa perlmaros: also another way to do it (in particular if you have things in different modules) is to use ::(‘ClassName’) as a reference which is resolved runtime rather than compile time. It’s a bit inelegant but in some situations I’ve found it’s the optimal route to use 16:04

finanalyst I'm just updating a META6.json file for Pod-To-Cached, which is now in the perl6 organisation. I want to change the auth field. Is `auth: perl6` correct? or `auth: perl6/Pod-To-Cached`?

guifa <.foo> in grammars is supposed to just be non-capturing? It seems to execute in a different scope than <foo>? 18:11
jmerelo guifa: what kind of scope?
guifa so I have a module that exports a single token, which uses other private tokens
finanalyst jmerelo: hi 18:12
guifa if I use <private-token> in the exported token, there’s no problem, it calls the token from inside my module
jmerelo finanalyst: hi, Richard!
finanalyst jmerelo: did you see my question about the auth field?
guifa but if I use <.private-token> it seems to want to use the scope from the grammar, rather than from my module, and bombs

tbrowder the merryostill fooling with Documentable.
can you answer the question ref CURI? are the installed distros actually compressed? 18:58
finanalyst tbrowder: the cache would be in the local system. So far it is only for the perl6 documentation
Don't know much about CompUnit at all. I only subclassed Documentable for the documentation system so that changes in Documentation files were not frozen. 19:00
tbrowder right, but i'm talking about modules in general. when one does "zef install Foo", is the installation representatio of that module actually compressed on the file system?
finanalyst don't know

cpan-p6 New module released to CPAN! ORM::ActiveRecord (0.0.6) by 03GDONALD
finanalyst Basically, I tried to replace --doc=HTML with --doc=HTML2 (my module), but HTML2 was 2x slower 19:06
Couldn't work out why. Then I found HTML2::render was called twice.
tbrowder i think he's right.
finanalyst Couldn't think how to work around the problem. Any hints? 19:07
JJ said the ast tree wasn't being passed to the render ????
tbrowder does the output look as expected? 19:09
sena_kun finanalyst, I am sorry to jam in, but do you know the two places where the module is called? I mean the stacktraces. 19:10
if you know the second path, you can likely trace it down to why it happens and write a patch
finanalyst sena_kun: thanks for the help. I reduced the problem to a short class with a do nothing render function. That was some months ago. I will need to go back and look. 19:11
sena_kun finanalyst, you can add `note Backtrace.new.Str` inside of the `render` function and get the code that calls it. 19:13
sena_kun goes afk
finanalyst sena_kun: just about to ask you that. You're a mind reader

sena_kun tbrowder, saw that, was very happy to see inlined documentation. :) 19:36
tbrowder well, that is my first use of it. formatting could use some work from the pod handler in core, but that is NYI. 19:38

tbrowder the module definitely needs some tweaking. for instance, i'm not real sure about when one really needs to specify .IO on a name. 19:41

finanalyst sena_kun: Backtrace does not provide much info. My Pod::To::HTML2 has a `sub render($podtree)` function with `note Backtrace ...` and `say $podtree` . Backtrace only gives the line numbers of these two statements, twice for each call to perl6 --doc=HTML2 20:26
sena_kun finanalyst, this is odd. :/ how can I try to reproduce it? 20:27
finanalyst sena_kun: Write a short module Pod::To::HTML2 , eg. .../lib/Pod/To/HTML2.pm6 . Have a sub render($pod) is export with just a say. In directory ... run `perl6 --doc=HTML2 -I lib some-perl6-prog-with-pod-in-it.p6` 20:30
sena_kun: is that clear?
sena_kun finanalyst, should be, let me see... 20:31
finanalyst, I am getting "No such symbol 'Pod::To::Foo'" for `perl6 -Ilib --doc=Foo a.pm6` and `lib/Pod/To/Foo.pm6` contains `sub render($pod) is export {...}` 20:34
MasterDuke does `Backtrace.new.full` give more useful info? 20:35
finanalyst sena_kun: trying to send you my HTML2.pm6 file by IRC. 20:37
I can cancel if this is bad ettiquette
MasterDuke: trying ...full 20:38
sena_kun well, I am trying to get it, but the connection is not going anywhere...
finanalyst, and timeout. :S 20:39
finanalyst, ok, changed that to class and `render` being a method, now it works, and is indeed called twice 20:41
and backtrace is not horribly helpful even with .full 20:42
finanalyst sena_kun: pastebin.com/z3zUssgZ
MasterDuke also, instead of manually inserting Backtraces, you could --profile=foo.sql and then look at the profile in moarperf. it'll give you callers/callees of functions
finanalyst sena_kun: my bad. I'm just coming back to the Module after a long time, and forgot the detail. 20:45
sena_kun finanalyst, no problem, and the thing I suggested is useless anyway, as I see...
finanalyst I raised this as an issue somewhere, in rakudo I think, when I first came across it. But it is a low priority thing. 20:47
sena_kun github.com/rakudo/rakudo/issues/2588
finanalyst I have rewritten Pod::To::HTML so that everything is in templates. That way, the same Module could be used to render eg MarkDown by changing the templates. But the Module is 2x slower than the standard Pod::To::HTML and I can;t work out why 20:49
I think Pod::To::HTML (the default for perl6) is special-cased in some way inside perl6
s/perl6/rakudo/ 20:50
20:53 zakharyas left
sena_kun ok, so I see it is installed to be called in Actions.nqp, method `install_doc_phaser` 20:54
the rule in Grammar.nqp is token install_doc_phaser { <?> } which obviously always matched, and is referenced in `comp_unit` rule 20:55
the question is how many times `comp_unit` rule is matched for this situation we are in
MasterDuke finanalyst: i'm not sure what special casing there would be. have you looked at any profiles of the default compared to using your module? 20:56
sena_kun github.com/rakudo/rakudo/blob/mast....nqp#L1416 20:57
github.com/rakudo/rakudo/blob/mast...r.nqp#L833
maybe the fix is to check if it was called once?
unfortunately, I am not much of a core hacker to know how to do that 20:58
finanalyst I tried to use a state variable in the render method, but since the method is being called by the compiler, it isn't recognising existing state. 21:00
sena_kun finanalyst, I mean to check if the phaser is already installed in rakudo itself, not in the module
lizmat weekly: perl6.eu/historical-intersection.html 21:02
notable6 lizmat, Noted! (weekly)
finanalyst MasterDuke: "looked at profiles of the default ..." I haven't because I don't know how. I'm running on Ubuntu. Can a profile be generated with perl6, or do I need another tool? 21:03
MasterDuke finanalyst: there's a built in profiling tool
`perl6 --profile` will create an html file you can just open in a browser. if the file is too big for the browser or you want some more functionality, timotimo++ is working on github.com/timo/moarperf. you use it with .sql files from the profiler 21:05
docs.perl6.org/language/performanc...le_locally has some more details/examples 21:06
sena_kun MasterDuke, the profiler says `render` is called twice for core#sources/D47B7F04B51CBB19CDF1E266B32AF87ACAE3A08B (Pod::To::Text):3 too 21:07
as well as for /home/koto/Devel/tester/lib/Pod/To/Foo.pm6 (Pod::To::Foo):3
so that means that it is a universal bug
MasterDuke yep, looks like
sena_kun left a comment at github.com/rakudo/rakudo/issues/25...-536341002 21:08
finanalyst MasterDuke: was just reading about profiling, then came back here. I see that sena_kun has already identified there is a double call, but the default still works 2x faster than mine. I'll work on this more 21:11

finanalyst MasterDuke: Something odd with Pod::To::HTML. I cloned it locally, then ran perl6 --I <path to local lib> --doc=HTML and I got an error that there is no render method. True Pod::To::HTML is written using sub's. So how does rakudo use Pod::To::HTML? 21:38
MasterDuke finanalyst:i'm not sure, i haven't looked at how the doc stuff is implemented in a while, definitely not since the recent refactor 21:40
but i'd suggest looking at the output of --target=ast 21:41
when it's working
that should show you what's going to be executed
finanalyst MasterDuke: Thanx. Getting late for me. Fuzzy thinking now. I'll look again tomorrow. 21:42
MasterDuke same here. i'd also suggest .asking jmerelo, he might be able to give a definite answer 21:43
sena_kun ast has two `QAST::Op(callmethod render)` 21:44
finanalyst JJ doesn't know. He suggested asking TBrowder, who also can't remember.
At first glance, it seems that rakudo uses the Pod::To::HTML module to create HMTL. But that doesn't seem to be true. 21:46
or perhaps not the whole truth 21:49
21:49 sena_kun left
MasterDuke finanalyst: hm, i can repro. `perl6 -I Pod-To-HTML/lib/ --doc=HTML -e ''` gives `No such method 'render' for invocant of type 'Pod::To::HTML'` 21:52
finanalyst yes thats what I get.
tbrowder try adding a mini pod block in the expression 21:54
MasterDuke same with `-e '=pod hi'`
tbrowder the incantation looks wrong 21:55
MasterDuke finanalyst: do you get the same thing if you install Pod::To::HTML with zef and don't try to -I the local clone? 21:56
