lue ohai! 01:29
Did I just hear that backtraces are ..... useful?
sorear snarkyboojum: don't forget certain non-core devs who make tests pass. 01:30
lue jnthn: if a part of Rakudo's insides were to fail, would it still look as nice as this? 01:37
jnthn lue: Well, not if the part of the internals is the backtrace printer. ;-)
lue: For subs in the setting, it should be able to do something sensible in theory.
lue: In practice we may have one more Parrot bug to fix yet. 01:38
lue .rnd(must .... get.... phone..... with MeeGo) 01:40
jnthn OK, dare I commit the backtrace code... :-) 01:41
sorear YES
jnthn :-)
We can debug and hack on it together to make it awesome. :-)
sorear It doesn't matter if you break all the spectests - it will still be worth pulling
jnthn sorear: Oh, it doesn't do that
All pass 01:42
Just didn't want to commit something that's even less helpful that the status quo.
But I think what I have now actually reporting real line numbers is more helpful.

 01:43
sorear I never payed attention to Parrot backtraces
jnthn sorear: Heh. Maybe nobody other than a few core devs did either. I dunno. :-)
sorear: They probably look a tad offputting though.
sorear No, they were better than your version 01:44
However, not containing any correct information compensated for the superior formatting
jnthn sorear: Heh, superior? :-) 01:45
What do you like better about the Parrot ones?
Also, patches welcome. ;-)
sorear I thought we had the various fields lining up, but I just checked and I misremembered 01:46
jnthn sorear: ah
sorear: But nice thought.
sorear also, I'd like to see more information in backtraces
01:46 whiteknight left
sorear like the PC value 01:46
(I really did use that)
jnthn Erm
Wow. :-)
sorear: In that case I'm going to suggest, let's provide a flag --pir-backtrace or something, that disables this. 01:47
sorear does your version know how to format long names when it's not being compiled into GLOBAL?
jnthn sorear: And then people can see the real Parrot backtrace and get the PC.
sorear: Not yet, that's one of the next things to add.
sorear What about code in other HLL universes?
jnthn sorear: It should be able to show that too.
sorear: It assumes it has a Parrot sub and anything more it can find out beyond that is a bonus. 01:48

Wolfman2000 *chuckles*
I'm hoping to get a new Macbook Pro in a few months. Should have plenty of ram and hard drive space. When that happens, I can try compiling Perl 6 again......unless you guys managed to make Perl 6 compile with a gig of ram with no problems. 03:27

Wolfman2000 goes to run the tests 03:43
sorear rakudo compilation has gotten a LOT faster in the last two months 03:44
it was around 10 hours when I joined the project for me
now it's down to 7 ... minutes
Wolfman2000 Compiler.pir took awhile to compile, but it...did its job
lue Maybe when R* comes along, I should try to compile on this old computer again.
Wolfman2000 It was about 7 minutes on my end as well, and I'm also pushing my ram usage to full.
Wolfman2000 is watching an iTunes U movie 03:45

but the question which I refer to is a semantic one, not a debugging one 04:35
take a look at STD.pm6:1430
notice that both sides of the alternation start with <.ws> 04:36
there should be no LTM going on, right?
TimToady ah, that is factored out

TimToady if there's whitespace before [ a | b | c ] it ignores the first whitespace on each alternative
Wolfman2000 ...and that should have worked
sorear TimToady: gimme5 factors it out, but I rather suspect it's doing so in error, since it changes the semantics - <.ws> ends a LTM pattern
TimToady a new LTM starts at the [] alternation 04:38
Wolfman2000 rakudo: ("5065726C36".comb(/<xdigit>**2/).map: { chr "0x" ~ $_ }).join.say
p6eval rakudo 8b3bb0: OUTPUT«Perl6␤»
Wolfman2000 there
TimToady each alternation is its own LTM

sorear I don't follow
TimToady but certaint that particular one stands on its own

so LTM shouldn't be able to affect which one is called?

pugssvn r30974 | sorear++ | [S05] Describe alternation left-factoring in rules, long implemented by gimme5 05:07
sorear what about sigspace with ~ ?
TimToady I think ~ currently screws up under sigspace 05:08
at the moment it's just a "Doctor, it hurts when I do this." 05:09
"So, don't do that."
sorear the viv component which reparses ~ currently just strips <.ws> from both sides
it runs a bit too low level though and even strips /explicit/ <.ws> ...
I wonder what the ideal behavior is 05:10
TimToady well, if we think of '(' ~ ')' <atom> as subbing in the <atom> for the ~, it kinda makes sense to transfer the ws to around <atom> 05:11
but generally, in practice, <atom> will be something that already handles whitespace
<statementlist> for instance
or EXPR
so the situation doesn't arise often in practice, and we could just say it treats it as '('~')' 05:12
sorear *lightbulb* the parsing behavior we want for ~ is exactly the same as for **
TimToady praps
sorear let's parse it as a psuedo quantifier
TimToady whatever works, and isn't *too* disgusting :) 05:13
sorear It'd be less disgusting than the current approach.
heh. I used $self->{dba} in the translation code for ~, but ~ is parsed with dba:additive... 05:19
TimToady you can always override the default dba

snarkyboojum is it a bug that you need to prepend a module sub with our to use Module::Name::mysub() ? 07:43
moritz_ nope, that's spec 07:44
you can also export them (doesn't need "our")
"our" means "put into the symbol table", and Module::Name::mysub() is an access to the symbol table 07:45
snarkyboojum oh, so the first example of day 12 is wrong

sorear: ok - I should look up the spec - the advent post indicates that they are, but perhaps they don't work for a good reason :) 08:21
otherwise why would people be writing out multi sub :)
sorear has just discovered that Q works in double quoted strings in Perl 5 08:23

masak as I understand it, package/module/class/role/subtype/enum names are relative in their declaration, but absolute in their use.

moritz_ smash_: do we have tests for it?

pmichaud no

masak probably cognominal's.
oh, ok.
pmichaud that one looks right.
masak which means names in declarations are absolute.
pmichaud no
it's because you (re-)used the A
not because the name is absolute

pmichaud as far as I know, that one is right.

that's, like, so inconsistent!

pmichaud look at it this way

pmichaud we should be able to find A::B
masak which was what all this was about.
names in declarations are absolute.
pmichaud no.
masak and not only those which you claim should be. :)
in Rakudo, they are.
pmichaud I agree that Rakudo gets it wrong (at least according to my reading of the spec) 15:38
let's consider this one:
rakudo: module Foo { module Foo { ... } }
cognominal so, it worked for member variable declaration but not for a sub definition
p6eval rakudo 1727ca: OUTPUT«===SORRY!===␤Illegal redeclaration of symbol 'Foo'␤»
pmichaud Rakudo is right there.
masak ok.
pmichaud because "Foo" always refers to the outer Foo that is in scope 15:39
it's not supposed to create Foo::Foo
rakudo: module Foo { module Bar { ... } }
p6eval rakudo 1727ca: ( no output )
pmichaud creates Foo and Foo::Bar
rakudo: module Foo { module Foo::Bar { ... } }
p6eval rakudo 1727ca: ( no output )
pmichaud also creates Foo and Foo::Bar 15:40
masak if you say so. :)
I haven't seen the spec say that, but I'm willing to find it in there.
cognominal rakudo: module Foo { my module Foo::Bar { ... } } # can it be private?
pmichaud it's the part that says there aren't any absolute module paths
p6eval rakudo 1727ca: ( no output )
masak :) 15:41
pmichaud they're always relative
and a X::Y name is always based on any X that is already defined
cognominal rakudo: module Foo { my module Foo::Bar { ... } }
p6eval rakudo 1727ca: ( no output )
cognominal ouch, xchat-- # tripped me again
masak I temporarily take back my accusations of inconsistency. I have to get used to this new way of thinking. 15:42
pmichaud masak: S10, "Package nesting"
masak oh, ok.
pmichaud first paragraph
masak I'm not sure I've ever read S10 :) that explains it.

pmichaud more interesting is something like

pmichaud module C { module A { module C::B { ... } } }
creates C, C::A, and C::B
masak aye.
pmichaud not C::A::B
cognominal makes sens to me
pmichaud or C::A::C::B
masonkramer why not C::A::C::B
pmichaud masak: because "C" refers to the outer C module
masak right. 15:45
pmichaud sorry, masonkramer

cognominal pmichaud: so the real interest of embedding is here privacy when used with my (not implemented yet)?
pmichaud cognominal: iiuc, "my" simply means that the symbol is entered in a lexical table but not in the package symbol table 15:51
cognominal otherwise it makes things more complicated to understand.
pmichaud module A { my module B { ... } }; # no A::B defined 15:52
cognominal I understand it is the Perl way to implement privacy
masak reads S10
cognominal ho, so with my, the logic is different to derive the absolute name. 15:53
pmichaud with my, there is no absolute name
cognominal And who cares because no why will use it
pmichaud it's effectively anonymous outside of the scope in which it was declared 15:54
cognominal agreed.
pmichaud even inside of the scope, I suspect it may have to be only "B" and never "A::B"
(because package A won't have an entry for B)
in comments above, likely s/UNIT/GLOBAL/g (after reading more of S11) 15:55
15:59 am0c left
cognominal pmichaud, on a totally different subject, should a match object contain a member with the name of the rule that was used for the match? I could see the use to create a link on a beautifier/debugger web based. 16:00
or does this member already exist?
pmichaud cognominal: that idea has come up several times. It's always been rejected.
cognominal ok, why? 16:01
pmichaud I don't remember exactly (more)
cognominal nevermind
pmichaud one question is whether we used the name of the rule used for the match or the name of the alias under which the match was stored
*use
e.g. <xyz=.abc>
16:01 tedv| joined
pmichaud (does the match object get "abc" or "xyz"? 16:01
cognominal tricky indeed 16:02

the 'xyz' is probably a key somewhere.
fwiw, I have written code which could have been simpler if such an attribute existed. 16:04
pmichaud masak: yes, that's why the question comes up frequently
masak so why is it always rejected? :)
pmichaud as I said, I don't recall exactly.
masak ok.
pmichaud (and I'm not the one doing accepting/rejecting) 16:05

pmichaud okay, so it has Parrot string semantics
moritz_ rakudo: '1 ' ~~ /.+/; say "$/".Str.PARROT
p6eval rakudo 1727ca: OUTPUT«String␤»
moritz_ why doesn't interpolation into "" makes it a proper Perl 6 string? 16:43
pmichaud rakudo is smart enough to optimize "$a" to be just ~$a
moritz_ how do I constructr a proper Perl 6 string from a parrot string?
pmichaud it should be happening automagically, really
but even that doesn't entirely explain it. why is Parrot string numification not working? 16:44
rakudo: '1 ' ~~ /.+/; say PARROT(~$/.Str)
p6eval rakudo 1727ca: OUTPUT«Str␤»

p6eval rakudo 1727ca: OUTPUT«1␤»
pmichaud rakudo: '1 ' ~~ /.+/; say +"$/ "
p6eval rakudo 1727ca: OUTPUT«1␤»
pmichaud moritz_: anyway, the simple answer is to make sure that Match.Str returns a rakudo string
moritz_ pmichaud: how? concatenate a '' ? 16:46
pmichaud or use prefix:~
or use substr directly
method Str () { substr($.orig, $.from, $.from-$.to) } 16:47
should do it.

If that happened, then CPAN and CPAN6 should try to _not_ mix with each other, for the sake of organization. 17:32

Su-Shee: perl6.org and proto.perl6.org probably help some.

jnthn moritz_: Code, from where I am, serves little purpose.
moritz_ TimToady: because 'my %h' needs a default type. That's Hash. 21:32
jnthn TimToady: Yes, but we actualy never create anything of type Code
21:32 Psyche^ joined, Psyche^ is now known as Patterner
moritz_ TimToady: my &c; doesn't have such a default 21:32
jnthn TimToady: Block inherits from Code, Routine inherits from Block and a bunch of stuff inherits from Routine.
TimToady: So all the stuff we currently have in Code could go in Block.
And Callable is left for "could I invoke this" 21:33
I guess the question is if we expect people create create callable things that should have some implementation commonalities with blocks but not be blocks.
*to create 21:34
TimToady are Thunks callable
jnthn I'd hope so. :-)
TimToady thunks are not blocks
not in the lexical sense
they are parasites on someone else's lexical scope
jnthn What would a Thunk and a Block share? 21:35
cognominal paste.lisp.org/display/110983 # how come the perl6 channel is no more supported?
jnthn That is, what would you expect to be in Code?
moritz_ are thunks user-exposed?
cognominal the pasted patch removes need_ext fossils in pmcs
TimToady they share the fact that they're callable, but that's a role 21:36
but a thunk is presumably an object

I accidentally added a file with git add
how do I take it back out before I commit?
cognominal git rm? 21:51
mathw and why do no simple git guides tell you useful things like how to fix mistakes
arnsholt mathw: It is my thesis that git is not intended for humans to use =) 21:52
Exactly how this fits in with git being quite nice on the whole, I don't know 21:53
mathw it's just... not quite done
arnsholt It's also documented and implemented from the inside out
mathw the only thing the user manual lists is git rm
which removes it from the filesystem! 21:54
I just don't want it in my commit
Eevee git reset HEAD file
plobsing IIRC, git status tells you how to remove it from staging
mathw oh yes 21:55
aaaaaaaaaaaaargh
must be time for bed

mathw phenny: tell masak I pushed some changes to Form which make it build on my system, but the tests fail. The first failure is in the parsing tests with some fields not parsing, so maybe Form::Grammar is now out of date. 21:58
phenny mathw: I'll pass that on when masak is around.

Spreadsheet_ Has anyone been working on an interactive Perl 6 REPL? 23:01
wolverian rakudo has one. 23:02
it's actually what is run when you run just "perl6"
what would a non-interactive REPL be like, by the way? 23:03
m6locks i sure hope it allows redefining stuff
it was a pain in the ass a while ago
when not allowing redefinitions
wolverian it doesn't seem to save state across lines... I guess that's a bit WIP then :) 23:04
m6locks i does
well, at least it did a while ago
wolverian it doesn't see my sub definition, but does see a class definition.
m6locks not sure if they have disabled it
well then it might be a bug and worth submitting
masak usually handles this type of stuff.... 23:05
