retupmoca timotimo: currently, I have the .dll right in the repo for zlib and openssl, since they're pretty small (very small, in the case of zlib) 00:07
but I'll add cairo and SDL to my todo list :)
and I can change the zlib/openssl .dll bundling to download like GTK does as well, if it's preferred 00:08
timotimo thank you very much 00:09
that'd be pretty cool

Augustus is anyone here familiar with the internals of NQP's regex engine? 01:02
timotimo i am a little bit 01:04
what in particular are you interested in?
Augustus I am wondering what is involved to create custom cursors 01:05
It looks like some of the matching logic is in the cursors
I was hoping that cursors were just handling walking through the input
timotimo may i ask what you're hoping to get from a custom cursor? 01:06
m: say "foo" ~~ / f { $/.CURSOR.WHAT.say } /
camelia rakudo-moar 01e174: OUTPUT«(Cursor)␤｢f｣␤»
timotimo m: say "foo" ~~ / f { $/.CURSOR.^mro.say } /
camelia rakudo-moar 01e174: OUTPUT«(Cursor) (Any) (Mu)␤｢f｣␤»
Augustus well I would like to make a cursor that generalizes from character sequences to sequences of arbitrary objects for one 01:07
but I would also like to make a bit-stream cursor
timotimo oh, i like the sound of that
but i'm not sure if that'll work well without also changing code-gen
tony-o Augustus++
Augustus it would also be nice to be able to make a cursor that walks other structurs
certain tree structures have in-order walks etc
timotimo walking tree structures can already be done quite nicely with gather/take at least :) 01:08
and since gather/take will keep generated values around, backtracking is also possible in a way
arnsholt Yeah, you don't want grammars if you want to traverse a structure
timotimo but using rules etc for that would be much better of course
Augustus can you use that to match a regex against it?
timotimo no, you cannot :(
but the design document says things about matching lists/streams/whatevs of objects against rules (that are specifically designed to handle that) 01:09
Augustus is that in an apocalypse somewhere?
I have not read through 100% of all of them 01:10
timotimo i thought it was in the synposes actually
Augustus even if there's no implementation I would love to read what other people were thinking on this subject
timotimo design.perl6.org/S05.html#Matching_...on-strings 01:11
sadly rather short :( 01:12
Augustus arnsholt: so long as you can reverse your walk in a well defined manner, or if you can suffice with simple look ahead, it makes sense to do regex matching against other structures
timotimo: thanks
timotimo hm
not as glorious as i had remembered
Augustus Forcing objects into Str can work for many interesting applications, but I think dealing with bit-streams is going to really require a custom cursor 01:14
timotimo you want non-byte-aligned specifically, right? 01:15
Augustus yeah
arnsholt Yeah, parsing non-strings is wanted, but not at all figured out ATM AFAIK
Augustus my idea is to basically compile textual regexes written with 0/1 or 0-9A-F into bit patterns 01:16
01:16 rararara left
Augustus and hopefully be able to do effecient byte operations when possible 01:17
and fall back to arbitrary bit stuff as needed
oh and obviously a special adverb on the regex to compile it to binary
probably also some special handling to deal with endianness so you can treat larger groups of bits as native integers 01:18
timotimo i wish you the best of luck with this 01:19
i'm going to bed now :)
gnite!

SomeStrangeTest hi - I'm having a problem installing Task::Star with Panda using rakudobrew 01:41

TimToady SomeStrangeTest: means self is a type, rather than an instantiated object 01:48
raydiak that error message might be better if it somehow mentioned or implied that type objects also mean "undefined"
SomeStrangeTest ok, that seems more likely...I see %!dists used here and there in the file and it really doesn't look like a type 01:49
this is from a fresh install of rakudobrew...what are the chances that it's broken? 01:50
TimToady the chances are always 50-50 :)
SomeStrangeTest :)
it appears my panda is altogether broken...just the command panda alone produces it 01:51
I may have confused it by installing in a weird directory
raydiak probably a totally different problem but I get a broken dependency on SVG when I try to install Task::Star...not sure where SVG went but it's...gone? from the whole ecosystem 01:52
I see the problem...trailing comma in it's new "provides" is invalid json 01:56

albert Greetings! When I try to install Task::Star with Panda I get the following error: "*resolve stage failed for Task::Star: Dependency SVG is not present in the module ecosystem". What can be the cause? 03:10
[Coke] albert: irclog.perlgeek.de/perl6/2015-03-31#i_10366478 03:11
Can folks examine S12-class/parent_attributes.t ? It's not run by default, fails, and dates from 2008. I suspect it might be no longer valid p6. 03:12
albert Thanks, Coke!
Sorry, Coke, but how this kind of error with meta.info files is supposed to be corrected? 03:26
raydiak albert: moritz (the module's owner) has to pull the fix after he wakes up (in Germany), which contains this change: github.com/moritz/svg/pull/2/files 03:30
albert Ohh, thanks! 03:31
raydiak yw :)
labster [Coke]: I use quotemeta in Perl 5 for two things: passing untrusted data into a regex, and passing untrusted data onto the command line. The first is deprecated now with double quoted strings, but the second use is still useful. 03:43
Though tbh, single quotes at the command line with that single quote escape '\'' would probably be better 03:44

masak I believe there's a notion of "canonical nth root" or something 07:32
it's whichever one has the smallest angle against the real axis in the complex plane
for square roots of positive reals, that's always a positive real 07:33
but yeah, there is some level of arbitrary in all of this
the most notable one probably being that -i could have been chosen as the imaginary unit, and it would've "all worked out", due to symmetry 07:34
masak .oO( how do you know they *didn't* choose -i as the imaginary unit, and that's what we have been calling i all this time ) o.O
moritz "by convention"
masak right. 07:35
the convention is largely sane, though.
07:37 jack_rabbit left
masak anyway -- don't think it was pointed out above -- you only get complex numbers from a calculation if you put in complex numbers as inputs. 07:39
that's why nwc10 got NaN
07:40 eli-se joined
masak I think it's a good default -- over the years, the only people I see being surprised by it are people who are testing Nth roots of negative numbers to see if complex numbers fall out ;) 07:40
and so it's a case like with `4..3`-style ranges. we could do more, and it might even seem cute today to do so, but it'd be more surprising and scary than useful. 07:41

psch hm, python and pry both stick with lines. that's probably neater if we can't supply a way to navigate up a line 10:55

if i do up arrow until i have something from the history and then left arrow i can't go through the history anymore 11:14

I would like it in the default REPL, but I'm biased since I've spent time on it =)
eli-se liblinenoise looks neat 13:23
psch fwiw, i'd rather just a have a powerful REPL in rakudo than having to install a package
'cause i often don't run panda when hacking on rakudo, but like using the REPL 13:24
tadzik +1
eli-se except that it doesn't support NUL inside line 13:25
hoelzro that would be an argument for including Linenoise.pm inside of Rakudo as well, then
nwc10 Star?
psch right. or some PP equiv
hoelzro nwc10: that was my original thought
tadzik I'm thinking it may end up like NativeCall eventually
hoelzro I guess it depends on the people who use it
tadzik core enough to just this pit along

erm, "just ship it", dangit 13:26
13:26 eli-se left
bartolin_ psch: do you have thoughts about tests for the REPL? 13:30
the other day I added t/S02-rakudo/repl.t to rakudo which has 2 or 3 tests right now 13:31
psch bartolin_: the first thing that comes to mind is that i probably should've run those against moreinput :) 13:34
i think testing it is definitely sensible, but i'm not sure how we can test e.g. tab completion
Files=1, Tests=3, 1 wallclock secs ( 0.02 usr 0.00 sys + 0.96 cusr 0.12 csys = 1.10 CPU)
on current nom for t/02-rakudo/repl.t :/
13:35 muraiki joined
bartolin_ regarding tab completion I have no idea how to test it :/ 13:36
but at least multiline input seems to be testable with subshells:
$ (echo {; echo say 1 }) | perl6 13:37
tadzik well, it should be enough to test the backend mechanics
13:37 rararara left
muraiki if I get a "longjmp causes uninitialized stack frame" error from moarvm when trying to use a p5 object via Inline::Perl5 inside of await/start, is it right to assume that the problem lies in the underlying p5 code not being thread safe? 13:38
psch ah 13:39
2/3 pass actually on repl.t
bartolin_ psch: with a rakudo from 2-3 days ago the tests in t/02-rakudo/repl.t pass for me
*nods*
it's only one of them
psch yeah, the last failure is expected with moreinput 13:40
because we want to allow «say "hi"\n if True;» we can't insert semicolons for every \n
bartolin_ it's the missing semicolon?
and it emits an additional newline if I add a semicolon 13:41
arnsholt Yaaay. Not being a moron means my page is generated in .3 seconds instead of 3.8 \o/
psch bartolin_: what do you mean? adding a semicolon to the end of @input-lines[0] passes the test for me 13:42
Ven arnsholt: what did you change :P?
hoelzro bartolin_: I have some thoughts on testing tab completion
I'm (not secretly anymore) working on a PTY module
13:42 raiph joined
arnsholt Ven: DBI->fetchall instead of loop with individual fethrow =) 13:42
hoelzro so we can leverage that
but including that in Rakudo seems like overkill = 13:43
=/
bartolin_ psch: oh, you're right. It fails, if I also add a semicolon to @input-lines[1]
nine_ muraiki: are you using Inline::Perl5 in a threaded program?
Ven arnsholt: hahaha
nine_: seems he is :P
bartolin_ ++hoelzro
arnsholt Ven: As I said, not being an idiot helps tremendously =D
hoelzro I'm going to use it to add tests to Linenoise.pm
hmm...if we include Linenoise.pm in Rakudo, should I get rid of my repo? 13:44
or maybe it's time to talk about "dual life" modules
muraiki nine_: yes; I was trying to play with await
psch hoelzro: a commit that empties the repo and adds a "has been moved to rakudo core" is what NativeCall does i think?
nine_ muraiki: you should be fine as long as you access a $p5 only from one thread. You can use multiple Inline::Perl5 objects from different threads. That said, this is very much untested territory. 13:45
muraiki nine_: thanks. sorry that I keep finding weird ways to break things :) 13:46
13:47 tinyblak joined 13:49 tinyblak_ left
psch hm, that's definitely a bug though 13:49
bartolin_ psch: btw, S02-rakudo/repl.t is not run with 'make test' at the moment 13:50
psch the additional newline when we echo into the interpreter and end on a ;
'cause it already happens with e.g. «echo 'say "hi";' | ./perl6»
nine_ muraiki: no need to be sorry. Thanks for helping to improve Inline::Perl5 :) 13:52
13:56 skids joined
bartolin_ psch: so you wouldn't mind if I add tests like '(echo {; echo say 1 }) | perl6'? (with your work one or two tickets from RT can be closed and it would be nice to have tests for those.) 13:57

ugexe how so? 15:59
moritz eli-se: well, if there's a module installer that can install a module for multiple compilers, and it uses only core functionality, depending on it doesn't reduce portability
PerlJam eli-se: does NQP count as a "perl 6 implementation"?
eli-se I don't know.
moritz I wouldn't count it 16:00
since it doesn't aim to implement some very fundamental Perl 6 elements
like lazy lists, the container model (assignment!), flattening 16:01
nor does it aim to provide most built-in types
TimToady and awesome error messages :P
PerlJam mostly awesome :)

TimToady well, there will always be corners where arcane semantics produce arcane messages, but we try to keep those corners in the corners 16:02
there's some kind of conservation of pretzel logic principle there 16:03
probably related to Gödel's Theorem 16:04

PerlJam I'm looking at the spec on open and the flags look weird. :r, :rw, :wa, :a once they are all implemented are essentially mutually exclusive. Also, they don't replicate the functionality of fopen's r, r+, w, w+, a, a+ and I'm not sure what we would call those things if we did them. 19:43
Seems like we should have :r, :rw, :w, :wr, :wa, :rwa map to the respective fopen thingies 19:44
moritz what's w vs w+ ?
PerlJam w+ is read/write, w is just write (which implies truncation)
moritz PerlJam: it seems like we should have :r, :w, :a, and be able to use, like, more than one
:r :w instead of :rw 19:45
PerlJam sure, but how do you distinguish between read/write that clobbers the file, and one that doesn't

PerlJam okay, what does read/write look like when you're appending vs. not appending? 19:50
I guess I'm wondering if there's a use-case to support fopen's a+
moritz :r :w vs, :r :a
moritz thinks he missed the point of PerlJam's question 19:51
PerlJam I'm probably just not thinking or explaining clearly :) 19:52
moritz there seem to be several dimensions here:
1) the allowed operations: reading and/or writing
2) whether the file is created if it doesn't exist
3) where the stream is positioned 19:53

SomeStrangeTest hi...trying to get rakudo installed and I'm stuck on the Task::Star step 23:28
error is " say defined %!dists;
"
oops
error is Could not find Template::Mojo"
this causes Bailidor to fail to install
tony-o how are you installing rakudo 23:29
SomeStrangeTest it lists a bunch of places it's looking for it, but I don't know where Panda puts things when it's trying to install so I don't really know how to proceed
following Linux instructions from here: rakudo.org/how-to-get-rakudo/ 23:30
I'm using rakudobrew
tony-o try doing 'panda install Template::Mojo'
SomeStrangeTest In hindsite that was obvious! :D 23:31
well I have a better clue now:
Zoffix I had the same error today. 23:32
Why does it do that?
SomeStrangeTest The distribution Template::Mojo does not seem to have a "provides" section in its META.info file,
and so the packages will not be installed in the correct location.
Please ask the author to add a "provides" section, mapping every exposed namespace to a
tony-o task::star probably doesn't have template::mojo listed as depends
Zoffix It does
SomeStrangeTest that error message suggests the problem is Template::Mojo
Zoffix github.com/tadzik/Task-Star/blob/m...A.info#L20 23:33
tony-o you can still install it without panda if you're just looking get past that step
SomeStrangeTest Yeah, Bailidor still fails to install with same error 23:34
tony-o clone [email@hidden.address] and copy the 'lib' folder to one of the directories listed when perl6 complains it can't find Template::Mojo (or one of the dirs listed by perl6 -e '@*INC.join("\n").say;') 23:35

SomeStrangeTest well that got me past that...on to this! 23:38
Compiling lib/Bailador/App.pm to mbc
===SORRY!===
No STable at index 12
build stage failed for Bailador: Failed building lib/Bailador/App.pm
arnsholt Success, sort of! 23:39
Using qqx rather than Proc::Async gets rid of the segfaults 23:40
tony-o SomeStrangeTest: can you gist the full error?
SomeStrangeTest where does Panda put stuff it's trying to build?
tony-o arnsholt: for what?
arnsholt tony-o: Running a subprocess and capturing its output 23:41
SomeStrangeTest tony-o: gist.github.com/JustDust/e3f2a76edf5897be25e4 23:42
tony-o arnsholt: are you using the .stdout.act or stderr.act on it? 23:43
23:43 flussence left
arnsholt Supply has an act method? 23:44
tony-o arnsholt: github.com/tony-o/perl6-overwatch/...rwatch#L62
arnsholt Huh. Didn't find that in the docs =D 23:45
23:45 flussence joined
tony-o i found it yesterday digging around in core 23:47
SomeStrangeTest is it more normal to just manually install rakudo and modules? I get the sense that I'm just making things hard on myself trying to use the magical stuff
tony-o SomeStrangeTest: not really, i'm looking for where rakudobrew panda does it's thing - can't really find it 23:48
SomeStrangeTest hah...yeah I'm wondering whether it's very careful about cleaning up because I don't seem to have any Bailador files anywhere :D 23:49
tony-o you might have better luck with manual install if you just want to play around with perl6 instead of debugging panda stuff
SomeStrangeTest: looks like panda creates a directory called .panda-work that it cleans up when panda exits 23:51
SomeStrangeTest bad panda!
ugexe thats not bad? 23:52
if you dont want it to go away do `panda look module::name`
tony-o yea i'd rather it clean up than leave .panda-work folders everywhere lol
i already have too much .DS_store 23:53
arnsholt Heh. 392 lines per second processed by my script
SomeStrangeTest well I suppose you don't want the files unless you want them!
arnsholt Blindingly fast =D
tony-o arnsholt: did that .act thing fix the segfault?
ugexe SomeStrangeTest: you dont keep or need all the files 23:54
arnsholt tony-o: Didn't try it
ugexe the modules need to be put somewhere to be compiled
which are then installed
tony-o arnsholt: i haven't had any issues with piping it to &print for a few thousand lines so i'm curious to know if there are issues 23:55
so i can fix it and make overwatch stable-r
arnsholt The script processes 1.4 million lines of text, which in its current incarnation takes an hour. Couldn't be bothered to try another approach right now =)
tony-o nice
arnsholt Probably a lot of time spent in NativeCall (for DB interaction) and grammars for parsing 23:56
23:57 coffee` left
SomeStrangeTest ugexe:sure I understand. It's nice though when things go wrong to be able to see what's happening. My preference is to leave a trail, but tastes differ. 23:57
particularly on a failed install it makes sense to me. When everything works, yeah blow away the temp stuff
but hey, that look command addresses that perfectly so I'm satisfied :) 23:59
