BenGoldberg So I've got a silly question... I realize of course that the "proper" perl6 idiom for returning a numerically 0 value whose boolean truth-y-ness is True, is "return 0 but True". However, it seems to me that it will probably be faster and more memory efficient to simply " 00:22
to simply "return '0e0';"

BenGoldberg Quotes matter
grondilu well, that's a neet trick. Maybe the optimizer could turn 0 but True into '0e0'

grondilu ah nevermind 00:27
BenGoldberg Well, ideally, the optimizer would create a singleton 0 but True object, and all places which do "return 0 but True" would really do "return $zerobuttrue.clone" or some such.

uvtc Hi, #perl6. I've seen the term "fakecutable" (fake executable) in the logs here and in #moarvm. What is a fakecutable? 03:57
Also, congratulations on the work news, TimToady. Sounds like a nice company. 03:58
Well, contratulations to them as well, actually. :) 04:02
BenGoldberg A fake executable is a script pretending to be an executable :) For example, a program named 'rakudo' which you can use to run perl6 programs, but which is actually an sh script instead of an executable binary program 04:04
04:07 xinming_ joined 04:08 jeffreykegler joined
uvtc Oh. Thanks, Ben. Yes. Like when you expect the program to be a binary, but it turns out to be a script which delegates to the binary --- or is a symlink to it. 04:09
04:10 xinming left
uvtc So, eventually, there should be a `perl6` fakecuteable which delegates to rakudo, or moar, or whichever Perl 6 impl you've selected/installed. Reminds me of the Debian alternatives system. 04:12
jeffreykegler TimToady: a very classy and assertive move by craiglist. As I understand it, your ability to devote full-time to Perl 6 will be a change, right? 04:13
uvtc r/installed/installed, I'm guessing/ 04:15
TimToady well, getting paid for it will be :) 04:16
jeffreykegler Again, congratulations on this much deserved piece of good fortune 04:18
uvtc Oh, little appearance of Perl 6 in a reply to <news.ycombinator.com/item?id=6559177>. 04:19
04:22 sniz left 04:27 [Sno] left 04:37 PZt left
diakopter uvtc: actually we use fakecuteable to mean an executable compiled from generated C that is a wrapper to launch the VM with your sript precompiled as bytecode or something 04:40
uvtc diakopter, Ah, that's a mouthful. :) Now I remember where I first heard that term. Back when Rakudo on Parrot was just coming on line, or, well, when a perl6 executable was finally becoming available. 04:43
diakopter, Thanks for the clarification. 04:45

moritz it's something to do with the Z metaop losing the container somewhere, iirc 13:20
or producing a new container
FROGGS masak: you are a git pro: how can I step back one single commit? like checking out one commit before the one I am on?
moritz git checkout HEAD^ 13:21
or if you want to revert your branch to it, git reset --hard HEAD^ # loses the newest commit, and potentially uncommitted changes
masak what moritz said.
I have the latter alternative aliased as 'git undo' here :)
moritz in #git I would have answered with !revert, which lists that and a few other options 13:22
(like git revert)
FROGGS ahh, cool
moritz: thanks!
masak also, the 'loses' is a truth with modification: when you have 'git reflog', nothing is really lost for a month or so.
moritz right, only the uncommitted changes are actually lost
timotimo except unstaged changes
masak right. 13:23
timotimo the uncommitted changes are not lost, if they are staged. but they are really hard to find :P
masak if you 'reset --hard', don't come to me afterwards and whine about uncommitted changes :P
timotimo: troo
timotimo: but then we are definitely not in the porcelain anymore, Dorothy.
masak .oO( timototo ) 13:24
moritz timotimo: so how does one recover formerly-staged diffs?
timotimo if you remember the contents, you can grep your object storage :P
masak moritz: they will be a tree object somewhere in the object db.
timotimo i don't think there will actually be a tree 13:25
masak there will.
the staging area is a tree.
timotimo since the staged changes are usually just in the index file, no?
masak hm.
timotimo oh, that also goes into the object db?
masak suddenly I'm not sure.

timotimo i thought a blob object was just the word "blob", a length and then the content or something?

zgrep doesn't do -r?! :-(

TimToady unless one prejudices the pretty printer to use the same kind of operator, asssuming such info is even passed through the ast 15:11

fglock specially multi-line comments in a column besides the code
pmurias: yes, that is something I'm playing with - to make a non-strict script strict by decalring the variables automatically 15:14
TimToady yes, alignment is nice, but not as critical as getting the info through
fglock or extract subroutines using vim

TimToady it's okay to guess as long as you mark the guesses with something that is easy to search for
with maybe a suggestion for how to make it guess the other way next time 15:16
fglock I think I can implement the comment stripper as a side effect of <ws>
like heredocs
pmurias reformating of the code seems to be an issue for the pretty print approach
unless all the code is formated with perltidy to start with ;)
fglock because it loses formatting, yes 15:17
TimToady typically just attaches the ws as an attribute of whatever the last token was
fglock it is a kind of perltidy, just dumber (or smarter, depends how you look)
but refactoring makes preserving attributes more tricky 15:18
pmurias you could try attaching the orginal source to pieces of ast 15:19
fglock maybe attaching comments to the top node of the statement, with (x,y) info

TimToady dunno, oughta be
masak sahadev: so it feels a little unintuitive to extend it that way. 15:49
sahadev: why not just re-add the line breaks with >>~>> "\n" ?
TimToady not all linebreaks are "\n"
15:49 berekuk joined
masak does it matter in this case? 15:49
TimToady thinks that .comb is the farthest thing from the user's mind when they're using .lines 15:50
so I'm fine with a :!chomp option
benabik .split(/<?[\n]>/) ?
masak anyway, I would pull a pull request with a :!chomp option.
TimToady but the fact you have to put ! there maybe indicates the default is wrong 15:51
diakopter or a coincidence of naming 15:52
TimToady so maybe :nl to include the newlines, or some such 15:53
masak +1
16:00 jeffreykegler joined
TimToady :newlines would be clearer, since :nl might be taken to specify what you want for newline 16:00

TimToady .lines(:delim(/<?after \n>/)) or some such
presumably whatever open uses for the same kind of option 16:25
PerlJam open uses :nl :)
16:25 autark joined
TimToady then :nl :) 16:25
otoh it feels like something that should be optimized relative to the normal chomp mode, and that's a pretty complicated option to recognize as doing something simpler 16:26
PerlJam It's weird that open has :chomp which subsequently affects get and lines 16:27
sahadev open uses :chomp too, which is a Bool, whereas :nl is not.
TimToady open's :chomp is what we're talking about deprecating
it's the wrong default 16:28

brk is fairly cheap when it's just extending an already allocated memory page
maybe it's one of those "allocate 100_000 things just in case" things :/ 19:03

er, :test(True) I guess

jnthn I think it expects whatever you supply the toake the same things a Rat constructor does 20:19

timotimo cool beans :)
jnthn yeah but it's compile time still :)
timotimo it's always nice that rakudo allows us to do stuff like that
yes, / and friends will still create rats if it can
20:21 LWA joined
nwc10 hangon, is that another of those insanely complex things that actually just works? 20:23
timotimo yeah
the compiler always does find_symbol('Rat') and friends when it builds constants etc 20:24
and that looks in the lexical scope
jnthn Ye,s if you stick that in a mdoule and export it then you have a pragma for "default 4.2 style constants to be Num not Rat"
timotimo so ... native num attributes in perl6 classes not supported with default BUILD? 20:26
coercive types are going to be interesting.
jnthn Yeah 20:27
It's part of the whole natives stuff that needs doing
20:27 kaare_ left
timotimo has no idea what that entails 20:30
same for coercive types
i'm also not sure if i'm going to finish the nodal stuff, i think i'll need some guidance for that some time

20:40 benabik left
nwc10 jnthn: "a sufficiency" 20:43
20:46 benabik joined
timotimo so ... a coercive type has a different type for typechecks and then does a coercion ... so is that using .Typename method calls? 20:46
20:50 berekuk left, dwarring joined
timotimo or how is it supposed to work? 20:50
for the simplest things like Str(Cool), it's easy, because then i can just say "oh, you mean to call .Str on any Cool that comes in" 20:51
and i suppose for custom types that can only sometimes work?
20:53 ssutch joined, berekuk joined 20:54 ssutch left
jnthn So far, my feeling is we need an nqp::istype variant that works in coercive contexts 20:56
And will accept a different result out
timotimo oh, so we want to pipe the value through nqp::istype and istype itself does the coercion? 20:57
what if we only want to check for match and not actually coerce?
jnthn No, we need another op...
nqp::istype will still be checky
I think that's how we want it.
timotimo and other things, like is $foo ~~ CoerciveType mutating for $foo? i don't think it should, actually.
20:58 ssutch joined
timotimo i agree, istype should not be magical like that 20:58
jnthn Well, that's where we'll need some spec work :)
We need to be careful at a level most people don't think of
Which is that coercion may involve a method call but certain things imply various type checks won't do that at present.
oh, that may not be true...
timotimo in my opinion, coercive types make sense mostly (perhaps only) in assigny situations like attributes, assignments and argument passing 20:59
that's the least implementor-torturing version i can think of, which may not be what we want to end up using 21:00
jnthn yeah, we need to define where they make sense and what there sematnics are in other places (possibly, error)
21:02 dayangkun_ left
timotimo how much is missing actually to make has num $.foo work? 21:06

jnthn Like, add some extra instruction codes 21:08

timotimo i don't know what that's supposed to mean :|

timotimo heh.

timotimo BUILD_LEAST_DERIVED is the only place where i have to work with buildallplan? 21:21
huh. i'm not actually sure why the buildplan is split into parrot and nonparrot 21:22
the only difference my eye can see is the use of atpos or atpos_s 21:24
oh, there's actually two copies, one for BUILDALL and one for BUILD_LEAST_DERIVED and the difference is probably just one line or something :P 21:27
but it's sufficiently hot code to require duplication for the tinyest difference
oh, it says why it needs to be different on parrot 21:28
21:28 berekuk_ joined
timotimo i'm kind of sad we can't just go ahead and do actual code generation 21:29
for the buildplan i mean
this still has things like strings for attributes instead of an integer slot for hash-less access 21:30
21:30 berekuk left
jnthn timotimo: Yeah, some hint_for love wouldn't go amiss :) 21:35

lizmat [Coke]: I think the method postcircumfix:[] and {} changes to sub should be mentioned in the short list as well, no?

bump VERSION to 2013.10
[Coke] lizmat: you did those, aye? Can you add a line for me? 22:53
lizmat will do
[Coke] lizmat++ !
my plan is to try to get the nqp release done before I head out for a bit, then do the rakudo release when I return. plenty of time for volk to edit the announcement and the changelog. ;)
