lue "NEL" and "NEXT LINE" are aliases for U+0085 , not the actual name. "NEXT LINE (NEL)" is the Unicode 1.0 name. It has no current Unicode name. 00:42

01:31 colomon joined
lue Mouq: there's no standard rule to match any kind of number, and convert it to decimal for you, so far as I know. 01:32
(though it would perhaps be nice if the rakudo side converted E<> things for you...) 01:33
Mouq lue: the latter is what I mean 01:34
lue: Though I'm not sure what to in the case of E<apos> etc
lue Like <somebody> said, at this point Rakudo's side needs to be founded on AST nodes, instead of building the collection of classes itself. E<> stuff is a perfect example of how ASTyness would be helpful. 01:35
Mouq: E<> is supposed to handle HTML entities, regardless of your chosen backend.
s/backend/generator/, to be clearer 01:36
Mouq perl6 --doc -e'=pod E<apos>' 01:37
apos
:|
lue: So what is desired behaviour there?
lue Output an apostrophe, clearly :)
(E<> definitely needs to be processed by rakudo, rather than backends) 01:38
::HTML happens to luck out with HTML entities, but ::Man and ::TeX and etc. would need to handle it similarly to how Rakudo would.
(if Rakudo didn't handle it, that is)
Mouq So rather than Pod::FormattingCode.new(type => "E", content => Array.new("apos")), you think it should be Pod::FormattingCode.new(type => "E", content => Array.new("'")) or Pod::FormattingCode.new(type => "E", content => "'")? 01:40
And then Pod::To::HTML can escape it itself?
lue Mouq: maybe? This is why ASTs would be better perhaps; it would be just another "plain text" node, perhaps with an attribute saying "special char; may need to handle this" 01:41
Mouq (with special casing for Pod::FormattingCode.new(type => "E", content => "\n") -> "<br/>"
)
lue But I definitely think it's detrimental to have every Pod backend implement E<> processing.
Mouq lue: And I'm not sure what you mean by AST 01:47
lue: What I've been saying about AST is that Perl6 should parse the code and generate an AST that builds the Pod at runtime, instead of compiletime 01:48
lue: But I'm not sure if you mean something completely different
lue Well, someone (I think tadzik) mentioned a while ago that perhaps the Pod parser in Rakudo should build a more QAST-ish structure, as opposed to the tree of Pod:: stuff it does now. (essentially, a tree of nodes that builds the Pod tree, instead of building the pod tree outright) 01:49
01:49 hoverboard joined
Mouq But the final output ($=pod and whatever's handed to Pod::To::*) would still be a tree of Pod:: stuff? 01:51
or do I misunderstand?
because I don't see a way around that
lue I forget what the specific issue was that gave rise to the idea, but presumably $=pod would hold the pod. 01:52
01:55 araujo left, araujo joined
lue Mouq: it came up while discussing M<> , and the person making the suggestion was you rather :) 02:02
Mouq: from S26: "By default, once the DOC INIT phase is complete, the interpreter then calls a special default DOC INIT block that walks the AST and generates the documentation, guided by the content of the $?DOC hint, the $=pod tree, and any DOC blocks that have loaded Pod-related handler code." 02:04
Sadly the "How Pod is parsed and processed" section doesn't seem to mention anything by way of processing *another* file's Pod from a Perl 6 script :/ 02:06
Mouq EVAL( $slurp ~ "\n$=pod")[0] :P 02:07
Which should really be like use File; File.pod or something
dalek ast: d429f6e | larry++ | S05-mass/properties-derived.t:

FROGGS thanks :o)
timotimo finally some breakfast \o/ 10:32
Mouq FROGGS: Does =NAME and so on work?
FROGGS ahh, and I need to think about a File::DistDir alike so that a module can load its shared data files
Mouq: you mean how a CU specifies its metadata? 10:33
Mouq FROGGS: mmhm
FROGGS no, I think that is not handled yet 10:34
I just cared about what happens when you install a distribution
Mouq FROGGS: Ok, it just caught my eye :)
FROGGS at that time you already have a META.info where everything should be included
so, some day we need a tool that bundles a bunch of files for release, perhaps creating the META.info on its own 10:35
10:39 darutoko joined
timotimo is that what perl5ers use Dist::Zilla for? 10:40
FROGGS but this tool is probably a combination of a local installed toolchain and a proper dist upload server 10:41

timotimo colomon: oh noes :( 11:34
it's tough being a module author
even tougher since i don't have any users, at least to my knowledge 11:35
colomon on the bright side, your module is pretty cool
timotimo what a relief :) 11:40
i appreciate the notifications in any case
it's slightly annoying to have a module that needs fixing every now and then, but it'd be much worse to have a module that silently fails as soon as someone tries it out 11:41

colomon o/ 11:44
colomon wonders if anyone else has tried installing File::Find on moar
tadzik timotimo: other than panda on moar? :)
colomon: I usually don't since updating modules that are panda deps usually breaks panda :|
timotimo tadzik: already in :) 11:45
colomon tadzik: emmentaler does it, and emmentaler / panda completely break when it does
tadzik oh, but it installs it to a different location, not updates the existing one 11:47
that should work, let's see
or am I one of those lucky fellas who can't connect to feather:3000?
...yes 11:48
colomon tadzik: I poked around the issue a bunch the other day.
tadzik IO::Socket::INET.new(:host<feather.perl6.nl>, :port(3000)) hangs for me
(on moar)
let's see if the update helps 11:49
colomon tadzik: for what it's worth, I think it's a moar bug and not a panda bug. 11:53
tadzik it is 11:54
lucky for me :D
ok, the bug is still there in the latest moar (for me)
timotimo aaow :( 11:55
aaw*
12:09 dmol left
masak colomon: thank you for the reports. 12:10
I looked into Text::CSV, but I couldn't identify the problem quickly. it seems parsing-related.
colomon tadzik: what it looks like is happening is File::Find installs (this is with pandabrew/bin/pandabrew panda install File::Find, but the same error comes from emmentaler), then when it wants to clean up the install process it calls rm_rf (Shell::Command) which in turn calls find (File::Find) and when that call is made, it bombs out with an illegal opcode. 12:12
tadzik huh 12:14
as if it indeed overwrote the original File::Find, and re-loaded it somehow?
colomon yeah, that's what it seems like, and that's why I suspect a Moar bug 12:16
it's not even supposed to be possible to trigger a re-load, is it?
tadzik to my knowledge, no 12:17
colomon once it happens, panda is completely borked until you rebootstrap it

masak Ven: I'm not following what you're saying. 12:43
Ven masak: from what I've seen in the community, the 1.9 had a nice list of breaking change (certainly not as much as perl 6 and probably less than py3), but people have been prompt to upgrade 12:44
masak Ven: that sounds quite likely to me. 12:45
Ven: maybe there is even some measure of "entrenched"-ness along which Ruby is much less affected than either Python or Perl.
Ven masak: maybe we're just hipsters who try the new things instantly :p 12:46
masak Ven: seriously though, I think it's connected to how much code you already have that'll break. 12:47
Ven: also possibly connected to how good test coverage you have.
Ven masak: that's why php people don't do any breaking change -- they don't have test </troll -- I'm sure that's not true>
masak: but I guess it works much better if, instead of a big list of breaking changes 12:48

FROGGS BenGoldberg: a file pragma (ha pragma!) would not help, because in the source code the backend specific stuff will still have other line numbers, and how would one debug virtual line numbers? :o) 16:12
BenGoldberg The backend specific stuff in gen/ comes from something which generated it, right? 16:14
TimToady it would help where the implementations are shared
FROGGS BenGoldberg: yes
16:14 rurban joined
BenGoldberg Then you'd point $?FILE and $?LINE to the file and line which did the generating. 16:14
FROGGS BenGoldberg: have a look at github.com/rakudo/rakudo/blob/nom/...e/terms.pm 16:15
TimToady $?LINE is a very funny constant, insofar as the compiler is allowed to change it on every line
FROGGS the first parrot specific block is short than the jvm one, so what is the common line number after these blocks? 16:16
timotimo p6weekly.wordpress.com/?p=82&sh...4aac3e4766 - after i wrote the biggest portion of this i took a rather long nap and didn't look over the whole thing completely yet, so it's probably missing a few important things
FROGGS it must be the biggest line number of all backends, so that there are holes in line numbering of the backends with short fudge blocks 16:17
but then you get a line number reported that either does not exist, or that does match a different position
BenGoldberg I'm not saying that the line numbers would always be common. They'd be common for common code, and point to the vm-specific line numbers for vm-specific code
FROGGS or the fudge scripts need to really put these holes in the generated source 16:18
I guess the last bit I said might actually work out
PerlJam timotimo: the last bullet point ends in the middle
16:19 arnsholt joined
arnsholt o/ 16:19
FROGGS hi arnsholt 16:20
BenGoldberg You only need "holes" if you only fudge the line numbers.
timotimo PerlJam: that's exactly the kind of thing i meant :D thanks 16:21
BenGoldberg If you fudge the file name, so so code in gen/*/terms.pm pretends that it is actually src/core/terms.pm, you can simply point to the original line numbers
FROGGS timotimo++ # I like it :o)
PerlJam timotimo++
FROGGS BenGoldberg: but then a backtrace line that points to after a fudge block would be reported for three different line numbers... ahh, now I know what you mean 16:22
BenGoldberg Continuing with the github.com/rakudo/rakudo/blob/nom/...e/terms.pm example, 16:23
The backtrace from the first common line of code after the first fudge block would be line 49 of src/core/terms.pm 16:24
And for all three backends, an error in any of gen/*/terms.pm on the corresponding line would appear to come from src/core/terms.pm line 49. 16:25
FROGGS yes, I got that now
BenGoldberg Ideally, no errors would appear to come from gen/*/, they'd all appear to come from src/code/*
:)

FROGGS I really love the idea, because it would not just silence camelia, it would even help debugging code 16:26
TimToady timotimo: [Xop] and [Zop] also rely heavily on recognizing list infix precedence of X and Z so that the arguments to the reduction do not flatten as a normal listop would
16:26 [Sno] left
FROGGS because when I add something errornous, I already have that terms.pm open at the errornous point 16:26
TimToady in any case, you should probably use the term "reduction" in there somewhere or people won't see the brackets
FROGGS a backtrace pointing to the gen'd setting that I ahve to open just to compare the text is, well, not perfect 16:27

nwc10 arnsholt: I think you need $Config{ld} (the unfortunately named variable for the *dynamic* linker) and $Config{lddlflags} 21:15
on the command line you can do things like: perl -V:ld.*
to get perl to print all config variables matching that pattern 21:16
21:16 gfldex joined
nwc10 but I assume that if you're in the JVM trying to ask perl for >1 variable, pass it a custom little program on the command line (or stdin) which uses Config 21:16
instead of shelling out $n times with a perl -V
arnsholt: this file might be useful. It describes all the variables that Configure records: perl5.git.perl.org/perl.git/blob/HE...g/Glossary 21:17
