TimToady I'm pretty settled these days 00:00
maybe I should write that part of the new book first :)
japhb :-) 00:01

TimToady my rules are perhaps a bit more finessed these days, given the various additional degrees of freedom, which all have their purpose 00:01
japhb Nodnod
TimToady these days it's more like "Know which of these principles you're emphasizing, to the detriment of other principles." 00:02

TimToady could be a superstitious comma, I suppose
japhb Sorta like that one? :-)
TimToady I paused there in my internal speec 00:24
*ch
japhb In any case, superstitious tokens are not supposed to be affect semantics .... 00:25
s/to be/to/
TimToady kinda like a block can have multiple statements without a Stmts node... 00:27
but this is a parcel without a comma node
japhb Would you expect there to always be one, or always not be one? 00:28
00:29 skids joined
TimToady well, comma just makes a list of things, so a list of things doesn't much care, I expect 00:30
a bit surprising it doesn't turn into 1 elem though
perhaps there's compensating code somewhere that strips the outer comma 00:31
japhb But only for the << >> case. :-/
rjbs Stringification of Buf seems a bit off for non-octet bufs. 00:33
m: Buf.new(100,200,300).say
camelia rakudo-moar 68c432: OUTPUT«Buf:0x<64 c8 2c>␤»
rjbs That 2C is probably a cropped 12C. 00:34
TimToady yeah, would be nice to prettify the ASCII subset at least, if not Latin-1
oh, that, it's just overflow
C semantics on small ints
rjbs Sure.
Oh, gosh, it's truncated in the buf, silently... 00:35
The docs only say: A Buf is a mutable sequence of (usually unsigned) integers.
TimToady it's a "feature" :)
rjbs I reckon I'll use an array.
The code I'm porting is my ZSCII codec, which maps between four states of text for working with Z-Machine: 00:36
japhb m: buf16.new(100,200,300).say
camelia rakudo-moar 68c432: OUTPUT«Buf[uint16]:0x<64 c8 12c>␤»
japhb rjbs: ^^
rjbs japhb++ !!
That'll do.
japhb It's because the default type specialization for Buf when it puns is uint8 00:37
TimToady Buf is really a role that instantiates for an integer type
rjbs (a) unicode strings (b) zscii strings [codepoints between 0 and 0x3FF] (c) zchars (d) packed zchars
In p5, it's easy: they're all strings. :)
which is also awful, of course
japhb rjbs: See src/core/Buf.pm for the gory details, and all the default specializations.

rjbs I find it hard to type "buf" and not "bug" :)
Okay, great. From now on, I type "buf8"

rjbs So is "buf16" an implementation-specific type? 01:24
TimToady no
it's a standard Perl 6 type
rjbs Great, thanks.
(I thought there was some convention about Int vs. int, but that memory is well aged.) 01:25
TimToady lower-case types tend to native, but that's not the same as implementation-specific 01:26
rjbs Aha, I see!
TimToady int itself is a bit ambiguous, compared to int32 or int64
it's not likely to be the same as int in C 01:27
p6 defines int as the largest integer that runs at "full speed"
rjbs I know how to use \c[...] to go from name to char, but how do I go from char to name? (in p5, via charnames::viacode)
TimToady so the native call interface tends to be more specific about C types as viewed in p6

and, well, ... laziness is a virtue, no? 04:10
TimToady maybe it does a parallel make?
just guessin'
it'd interleave other messages though if that were the case 04:11
raydiak really with dynamic underclock and overclocking, I guess I wouldn't read too much into it unless it's repeatable
it is getting warmer here than it has been
TimToady could just be that
blocking the vent can have that effect too
raydiak just on a tabletop atm 04:12

TimToady that can cut the air gap underneath
raydiak clever, didn't consider that one, but nope
TimToady out of ideas for the moment... 04:13
raydiak though, I'd probably notice that too, that rocking diagonally thing drives me nuts when it happens

TimToady free space doesn't matter if it's working up toward a head crash
TimToady is full of good news... :) 04:18
raydiak :)
raydiak wonders if his system meters do something dumb like ignore nice time or something 04:19
TimToady just uses top to see what's really chewing time
raydiak ah! I got a plausable one! if a process acted up *after* I started the build, I wouldn't be able to tell on the meters because of all the noise 04:20
TimToady could well have been a cron job running at the top of the hour then, if you'd just finished at 2 after
raydiak I'll bet that's exactly what happened. 04:21
raydiak will build again later, but has gotten hisself way out in left field from his originally intended direction, and still intends to head that way :) 04:22
TimToady well, hope you get to first base then 04:23

Anyway, once we're all tightly sealed up in our automated capsules to shoot us from one building to another, you don't really have to interact with most of the outside world any more, and you don't need cops so much.
You also take some heavy losses in the form of creativity, freedom, fresh air, human spirit, the diversity of natural things like weather and plants, and so much more...but nobody seems worried about those kinds of qualitative factors any more. :P

could you elaborate?
cygx my confirmation was to soon: while I can seek, I can'T read from the file... 08:29
masak: well, I would have expected :a to work as in POSIX
masak I'm out of my depth here. I don't know how :a works in POSIX. 08:30
but to the extent I understand what you're saying, I agree -- we probably shouldn't be violating POSIX convention. 08:31
we're usually quite keen to keep to POSIX convention, in fact.

it's actually MoarVM that only supports 3 modes, not just Rakudo :( 08:45
masak I think I understand all of them except "rw(update)". how does this one differ from, say, "rW(append)"? 08:48
brrt i think write-only doesn't clobber but truncates first

RabidGravy what is "write string requires an object with REPR MVMOSHandle" trying to tell me? 11:43
jnthn RabidGravy: Maybe that you pulled a very busted Rakudo a couple of days ago that failed that way on everything 11:45
It did so because we modified PROCESS:: during the BEGIN time of a module's pre-comp, which will screw up the standard handles.
(We can't really fix that in general, it's just going to have to be one of those pre-comp rules.) 11:46
Guess it's possible you have a different issue though.
RabidGravy Hmm, I'll test that, but it's weird because if I run the code in question with "perl6 -Ilib <path>" then it's fine 11:47

arnsholt From memory, it first tries to load the thing as-is, and if that fails it tries to load with shared library extension
rjbs Should I hack it before installing?
(I don't see a .pmc file or anything, should such things exist.) 12:38
arnsholt Which file did you edit?
The .pm installed by panda, or something else?
rjbs ~/perl6/share/perl6/site/lib/Linenoise.pm

arnsholt Right, right 12:38
In that case, there's probably a precompiled version lying around 12:39
Linenoise.moarvm
hoelzro rjbs: I thought you were also having trouble with panda installing a .so instead of a .dylib?
jnthn rjbs: I'm entirely the wrong person to kvetch at if you want a useful answer; I didn't do any of the Linenoise module work, don't know much about OSX (apart from its debug malloc library :P), and didn't really hack on Panda either :)
rjbs jnthn: Thanks anyway. Someone had wondered whether perhaps moar was doing dylib loading incorrectly, but it looks like that is not the case, now t hanks to arnsholt++ 12:40
Ven arnsholt: do you have the source doc for the `__class__` python behavior?
rjbs hoelzro: No, it installed .dylib
Ven or maybe you were looking at source code
rjbs There is a .moarvm file, yes.
arnsholt Ven: docs.python.org/3/reference/datamo...s-creation "__class__ is an implicit closure reference created by the compiler if any methods in a class body refer to either __class__ or super. "
hoelzro rjbs: ok, good. what if you repalce all of the liblinenoise.so with liblinenoise in Linenoise.pm in a clone of the linenoise repo, and panda install that?
Ven arnsholt: thanks 12:41
rjbs The plot worsens...
So, I removed the .moarvm, I edited the .pm, and now I get:
Cannot locate native library 'liblinenoise.dylib'
hoelzro: I will try that. How do I panda install "the repo whose working tree I'm in"?

arnsholt geekosaur: What is the correct solution, incidentally? 12:49
That's one of the annoying things with shared libraries; convincing the linker to find the damned things 12:50
hoelzro rjbs: glad to hear it =)
geekosaur OS X encodes the runtime path to the dylib within the dylib itself. generally you use install_name_tool if you need to adjust that 12:51
this may require linking the dylib with -headerpad_max_install_names to leave sufficient room for large paths 12:52
but in short, if you copy a dylib somewhere other than where you built it, use install_name_tool to fix its internal path 12:53
hoelzro jnthn: if you have some time today, could you look at RT #125154? I was able to fix it by reverting a commit you made a year ago (319509a), but I would like to keep the gains that resulted from that commit

jepeway well, gone, again. still interested in why Int.new(0) is a bust. would love DateTime.utc to be able to use $.timezone.new(0) so it won't slice off timezone types. 12:58
masak goes and reads S06
geekosaur because DYLD_LIBRARY_PATH overrides the hardcoded paths completely. so if you have something using the libiconv.dylib Apple ships, and you include the library directory for macports or homebrew or anything shipping a newer gnu iconv in DYLD_LIBRARY_PATH, that thing thta expects Apple's will crash hard 12:59
12:59 skids joined
geekosaur DYLD_FALLBACK_LIBRARY_PATH will try the specified one first and only then search the fallback path, so all the system programs will still work even if you have an alternative version of an Apple-provided library somewhere on it 13:00

rjbs geekosaur: Right. It'd be nice if there was an error on my misuse, I think, but whatever. :) 13:13
13:13 Ven left
geekosaur it might be necessary to use install_name_tool -add_rpath on perl6 to point to the directory where libLinenoise.dylib is for dynamic loading 13:14

RabidGravy so, any ideas where to start looking for the reason that simply loading a compiled module might be shagging up $*OUT?
rjbs hoelzro: It's fine now, but I think it's because of the changed keyboard profile 13:47

geekosaur yes. something turned on application keypad mode, resetting the keyboard profile turned it back off

geekosaur most unix stuff doesn;t use application keypad mode, it's mostly a vms thing 13:48

Which sucks if you're doing live demos. :)
TimToady I agree
Ulti +1 for strict in REPL I'd want the REPL environment to be near enough the same as a script executing

Right. :)
I can up arrow fine on Windows :D
It's you backwards *nix folks who need the silly libraries to enable it :P 17:00
Ulti the main use case of a REPL for me outside of P6 is debugging a script where I copy paste lines

Any preference?
17:16 domidumont joined
dnmfarrell hey #perl6 I'm trying to define a grammar that recognizes "include" tokens for other files to parse. I can get the grammar to parse the referenced file, but how can I include the resulting match object in the parent match object? e.g. "token include { ^^\=include \h+ <text> \n { $/ = self.parsefile($/<text>.Str) } }" 17:17
TimToady jnthn: nope
dnmfarrell: either with 'make' to store into the .made slot, or return $/.CURSOR directly might possibly work 17:18
jnthn Or stash it in a dyncar if you want to reach it from the actions
dnmfarrell TimToady: jnthn thanks! let me try those 17:19
jnthn uh, dynvar :)
TimToady still thinks some of our internal dynvar usage is a bit smelly
17:19 diana_olhovik_ joined
TimToady $*ACTIONS is probably slowing down the parser, both directly and through opportunity cost to the optimizer 17:20
jnthn TimToady: Indeed, also by making a polymorphic callsite 17:22
TimToady and language braids probably should be coming in through cursors, not %*LANG
jnthn TimToady: Whereas if we could grab the actions from, say, ParseShared, then we could do the grab and invoke in the code we compile, not down in !cursor_pass, maybe
TimToady but that's more about correctness than speed, I'll warrant 17:23
jnthn TimToady: So it becomes monomorphic and so inlinable/specializable
So yeah, it is sub-optimial in 2 ways to do actions as $*ACTIONS
TimToady one would eventually like the action code to just be a kind of wrapper for an inlined parse rule, maybe
or automatically added to the end of a parse rule so there's no invoke at all 17:24
jnthn Well, adding the call at code-gen time is what I was thinking of.
And spehs can decide if inlining is worth it. 17:25
*spesh
TimToady nod, so probably equivalentish
jnthn Aye
It'd also fix that RT about spurious calls when .parse is not passed a :actions
TimToady maybe also there's some generalizing to the forest/frogs kind of deriving multiple classes in parallel we want to think about 17:27
which I talked about in one of the apos but never got much traction
I suppose people would call that the expression problem nowadays
kinda touche on AOP too 17:28
*es
jnthn I'm kinda touché on AOP also :P 17:29
TimToady AOP is one of those half-paradigms :)
I'd put DBC in the same category

nwc10 sorry if this is a daft question - was there some type of Perl 6 time counter which is seconds since Jan 1st 2000? 17:44
TimToady Instants are TAI based, so just a difference
or did you wish to ignore leap seconds? 17:45
nwc10 no, right now I'm blissfully able to ignore time (as SEP - I'm getting to deal with URLs and legacy code) 17:46
but I had this vague (and it seems wrong) memory that something in Perl 6 was calibrated relative to 2000, instead of (say) 1970, or some other arbitrary epoch
actually, to be very fair, nearly everything is now SEP until Friday, as tomorrow is a public holiday 17:48
TimToady that was my original proposal in 2000, but since then they've continued to use leap seconds, and we've settled on a more epoch-less view of time

RabidGravy If one has a A.pm "module A { my $foo = $*DISTRO.Str; }" and a B.pm that can be just "use A; class B { }" and they are compiled and installed, then doing "use B;" in a script will cause $*OUT to get shagged up like that 18:10

TimToady which means nqp might be depending on it

do we even have ranges in nqp?

cygx PerlJam: in my branch, the argument to nqp::open corresponds to POSIX O_* flags, so translation from user-visible flags is necessary 20:17

PerlJam: that's why that open is a private method as its signature is an implementation detal 20:18

PerlJam cygx: sure, but why do you need to pass both to !open() ? It really only uses $llmode. (what it uses $mode for looks like it could glean from $llmode)

cygx PerlJam: if I omit either of the mode arguments, there's no way around implementing another lookup mechanism 20:20
20:20 rurban left
PerlJam cygx: in your modified version of !open, $mode is *only* used if $path eq '-' from what I can tell. It seems like you can get the same information from $llmode for that purpose and do away with $mode entirely. 20:24
20:28 darutoko left
cygx PerlJam: it's also part of the error message of the `$!path eq '-'` branch in guise of $_ 20:28

tony-o_ i could do that too, the problem is i don't know exactly what's going to be happeningi n the start block
hoelzro tony-o_: you want multiple start blocks to share a single closed over variable? 21:31
tony-o_ it sounds that way, i'll show you my actual code: github.com/tony-o/perl6-green/blob...en.pm6#L84 21:32
hoelzro tony-o_: what about multiple threads messing with shared state, though? 21:33
tony-o_ here is the test file for that - github.com/tony-o/perl6-green/blob...-sets.t#L8
hoelzro that sounds iffy
TimToady it ought to find the $*SET in the lexpad anyway 21:34
tony-o_ with the dyn vars i get 'Any' for $*SET after the first call
so it finds it but it's always undefined on subsequent calls 21:35
21:35 colomon joined
TimToady maybe cached it too early 21:35
tony-o_ what does that mean? 21:37
TimToady the thread keeps an old dynamic scope around that looked up the dynvar too early, so has cached a value of Any 21:38

Right. Instead, I'm using #perl6 for that, and am very thankful for everyone's extreme forbearance. 23:19

23:44 raiph joined
rjbs I keep forgetting which thingy is meant to be buf8 and which buf16. Hooray for type synonyms! 23:44
and constants are default lexically scoped?
I can test tha tmyself, nm.
TimToady constants and enums are our by default 23:47
rjbs Okay.
TimToady but you can say my constant
rjbs I may just do that!
We established the other day that in Buf[X], X has to be a native type. Is that "just now" or "forever"? 23:48
TimToady I suspect it's temporary, but jnthn would know more
rjbs Okay, not important atm anyway! 23:49
TimToady we do try to guarantee continguous memory, and that's sort of antithetical to pointer indirection
Str can be implemented as ropes, but Bufs aren't allowed to do that, on the theory that you want to pass them to/from external APIs 23:50
rjbs moarvm does ropes, doesn't it? I seem to recall nwc10 talking about working on ropes for it at some point. I was surprised. 23:51
What you say makes sense, for sure.
TimToady it does use ropes for some things currently, but isn't terriby smart about it yet
rjbs It's fun: the more I work on porting this code, the more it is clear how Perl 6 is very distinct from Perl 5. I already knew this, but I am getting to better bellyfeel it.
TimToady lots of places it gives up and flattens the ropes
well, we tried to fix everything, which is why it took so long :) 23:52
