holyghost perl6 sound software, here I come ! 03:01
yoleaux 25 Nov 2018 17:05Z <jmerelo> holyghost: nobody removed you from the schedule, you were never actually there. If you want to write something, please use some repo to publish and we'll review it before accepting.
lookatme_q what is sound software ? 03:02
holyghost I am programming a search for a pattern in the nth channel 03:03
I use a matrix to interpolate the 8bit channels in a WAV file, then I have larger numbers to compare for the search of a sample/pattern 03:05
Later on I'll do effects 03:06
all from the command line
on e.g. aiff/wave file samples
The biggest thing would be to rip a voice from a WAVE file 03:08
Then when I have my voice or other samples on disk, I can use them to make new music in a sound editor
lookatme_q Play a WAV file ? 03:10
holyghost ?
I reap WAV files then sort out patterns in the WAV file, them write those samples to disk, then I can as you say play the WAV file 03:11
lookatme_q Do you mean you make a command tools can make new music ?
holyghost yes
lookatme_q oh
holyghost then do effects on the sample WAV file 03:12
then with the pieces/samples in WAV files I can edit in a wave editor and mix 03:13
I might make a player too
lookatme_q Have you finish it yet? 03:14
holyghost no
lookatme_q Cool work
holyghost thanks :-)
03:14 coet left
lookatme_q Is this tools written in pure Perl 6 ? 03:15

timotimo hey Xliff
Xliff Oh, hey!
jkramer Shouldn't this work?
Xliff timotimo: I am having a weird issue with Cairo. I had an example that was working a few weeks ago, but now it is not. 10:23
timotimo jkramer: i think you're running into the problem that xx thunks its LHS
Xliff: oh, that sounds interesting
Xliff timotimo: Tracked it to here -> github.com/timo/cairo-p6/blob/mast...pm6#L1250. Error message is "Cannot modify an immutable Operator (OPERATOR_OVER)
"
timotimo ah!
all those proxy returning methods require an "is rw" 10:24
Xliff Subtle change in rakudo? I can't see anything in Cairo's commit log that cause this.
timotimo let me handle that real quick
Xliff LOL! Thanks!
timotimo yeah, it was a bug in rakudo that was discovered long ago, but we decided to be bug-compatible for a while
Xliff Heh. 10:25
timotimo pushed to github 10:26
Xliff Thanks! 10:27
Bump version? 10:28
timotimo yeah
bumped 10:29
Xliff :)
Yeah, so it's official. My GTK monster is now using your module as a dependency. 10:30
Next thing is to tackle Pango.
timotimo yeah, someone else also asked for being able to render multi-line strings with cairo
oh, btw
there is a way to render two lines of text with cairo
actually, any amount of lines of text is possible 10:31
10:31 vike1 left
timotimo a friend found this out recently 10:31
Xliff Neat!
timotimo you can put <span></span> elements in your text
Xliff Not surprising with the push to CSS and markups from Gnome
timotimo all you need to do is give every letter its own span, give them correctly calculated horizontal offsets and vertical offsets and then just put the letters of all lines next to each other
so the text would be "hweolrldo" instead of "hello" and "world" 10:32
Xliff Yeeks! That sounds like a lot of CSS!
10:32 vike joined
timotimo yeah 10:32
it's not workable in practice, of course :)
Xliff Still neat though.

jdv79 for instance - if you fire off a large number of tasks with "timeouts" aka anyof(start {}, Promise.in()) it'd be nice to now run all those "timeouts" if not necessary. not a huge deal "normally" but at at certain rate it may be significant. 16:10

Here's something interesting from a perl6-gdb-m backtrace. The answer to the imposed question is most assuredly: "YES"
gist.github.com/Xliff/600d6e0baaa1...3d9f4c05f6
Still looking for how I can figure out what caused the problem. 16:35
timotimo Xliff: this is with the jit enabled? 16:36
Xliff Yep.
Want me to rerun with it off?
timotimo yes
the jit messes up stack traces
null_args_callsite and inv_arg_callsite aren't functions, they're constants. the instruction pointer isn't supposed to land in them 16:37
and it doesn't
it's just that the stack isn't in a format that gdb expects
Xliff Yeah. I was getting floating segfault in this code.
I figure it's something I'm doing with NativeCall, but it's making it hard to track. 16:38
timotimo i seem to recall you tried valgrind already?
Xliff Turning off the JIT has prevented many of the earlier ones, but I am still getting them later in the routine.
Valgrind was for something related to CArray that I still haven't figured out yet. I did gist about it for a piece of test code I wrote. 16:39
But this is something unrelated.
timotimo OK 16:40
Xliff OK. Updated with another segfault. This one is fairly common, but there is no tc. 16:41

timotimo if you know which thread it actually is, you can find threads from another thread's tc->instance->threads (or something) 16:43

Xliff I'm worried it's my broken implementation of GList. 16:44

lucasb do you mean move all mu/misc/perl6advent-* stuff into a new repo "github.com/perl6/advent" ? 18:34
I think it's a good idea. the mu repo is filled with unrelated stuff 18:35
just making sure not to lose any files in the moving :-) 18:36
this would open way for a static site hosted at "perl6.github.io/advent" 18:39
generated by Jekyll with Perl 6 syntax highlighted, yay!
j/k, I'm not suggesting this, although I think it would be nice 18:40

Xliff timotimo: Do you know why I get this error "This type cannot unbox to a native number: P6opaque, Int" when I run this: "$cr.set_source_rgb(1, 1, 1);" ? 20:56
OH! 20:58
This works: "$cr.set_source_rgb(1.Num, 1.Num, 1.Num);"
timotimo right, "number" here is supposed to mean "num"
might be a good idea to put that in there explicitly 20:59
20:59 robertle left
Xliff Yeah, all Cairo objects now use Cairo *_t equivalents, so I don't have to cast. 21:00
That means I don't get the benefits of Num(Cool)

Xliff I'm getting a lot of these, lately. "MoarVM panic: Internal error: Unwound entire stack and missed handler" -- Could this be due to exceptions in C code not being handled properly? 22:06
22:06 kensanata left
timotimo "impossible to handle", more like 22:07
Xliff Well, shit.
Whatever is happening, is happening in the C layer, and I can't trace it to any MoarVM code.
Would be nice to know the last line executed, but I'm afraid its in a signal handler. I know what action causes the problem, though. 22:08
timotimo what i tend to do is wrap every callback in a CATCH 22:13
and since often enough the error that occurs is from binding arguments to the callback, i tend to give it a signature of |c first 22:14

Manifest0 Can someone explain why this works: perl6 -e 'my @array = (()); push @array[0],1; say @array; ' ? Shouldn't this be an array containing a immutable list? 23:39
23:41 kurahaupo left, ryn1x left
Manifest0 For example this doesn't work: perl6 -e 'my @array = ((), (), (), ()); push @array[0],1; say @array; ' 23:43
leont Because my @array = (()) creates an empty array 23:44
my @array = ((),) will fail as you expect
Manifest0 () is an empty list. Shouldn't this be an array with an empty list? 23:46
The documentation states: "There is one exception, empty lists are created with just parenthesis" 23:47
timotimo an array constructor will iterate its outermost thing passed 23:48
which is also worth knowing
m: my @array = (()); dd @array
camelia Array @array = []
timotimo m: my @array = ((),); dd @array 23:49
camelia Array @array = [(),]
