masak # Connect failed with error Cannot locate native library 'libsqlite3.so' 07:59
...this is after I did `sudo apt-get install sqlite3`.
what am I missing?
I suppose it's NativeCall that expects to find libsqlite3.so in a certain place. but where? 08:01
08:02 FROGGS joined
masak doing a `locate libsqlite3.so` turns up 5 hits. 08:02
08:03 ptc_p6 joined
moritz masak: hopefully somewhere where ld finds it 08:04
masak ok, backing up a bit.
I'm on a sensible Linux system. I want to use DBIish with SQLite. what do I do? 08:05
the DBIish project doesn't seem to contain instructions for how to get started. I'd love to be proven wrong on this.
assume I'm good at following instructions, but not an expert at things that end with .so 08:06
moritz TBH, I don't know 08:08
last time I tried it, it simply worked
masak I skimmed `man ld`. now I'm more confused.
bonsaikitten masak: by default things should be in the paths defined in /etc/ld.so.conf
that's where the dynamic linker will search
moritz so I guess I installed libsqlite3-dev 08:09
bonsaikitten if you have it in divergent locations you could use LD_PRELOAD to hack around it
masak ok, my /etc/ld.so.conf includes another file, /etc/ld.so.conf.d/i686-linux-gnu.conf, which mentions /lib/i386-linux-gnu, in which I *do* have a file libsqlite3.so.0 08:11
so by that measure, it oughta work.
masak tries installing libsqlite3-dev
that did it. moritz++
bonsaikitten actually ld.so.conf is only the human-readable config, 'ldconfig' command creates a ld.so.cache that is a more efficient binary format 08:12
so any updates will only become 'visible' after running ldconfig (which package managers usually trigger themselves) 08:13
moritz masak: if you're on a 64 bit linux, the /lib/i386-linux-gnu is probably a directory for 32bit libs, or something

introduce a SYNOPSIS

A good synopsis helps someone get started by providing a likely code template that can be modified and built upon.
The README.md had no SYNOPSIS, and the main module file had one that targets
  developers of the module, not users.		 08:21

masak I'm trying to formulate something about how I use the "cool" features of Perl 6 much less than I think I would have predicted back in 2005. 12:29
junctions, hypers, chained comparisons, metaoperators in general, even defining operators.
when I *do* use them, I'm very glad they're there. 12:30
but something like 95% of code I write is very down-to-earth and doesn't use such features.
lizmat perhaps a blog post about this is in order ?
masak on balance, I'm much more happy about bigger features like classes/roles/methods/attributes, grammars, and Perl 6's tendency to be very refactorable. 12:31
lizmat because I think that's a very important point to make from someone in the "frontline" of using Perl6 in production

user3 I have rakudo on Windows (3 Sept version) and Linux (parrot, 30 Aug). when I type perl6 at the command line and enter a session I can cycle through my commands with the up/down arrow keys on Windows but not on Linux. on Windows, is that a Perl 6 feature or is it just the up/down arrows mechanism of the cmd.exe command line? 12:49
moritz user3: it's a perl 6 feature 12:50
user3: different backends use different libraries for that 12:51
FROGGS user3: it depends on what readline library we use on these systems
on linux we can use libreadline or liblinenoise
moritz user3: for example if you use the parrot backend, you need "readline" and its development libraries installed when you configure rakudo and parrot
FROGGS user3: in case you want to build rakudo on MoarVM on linux there is an interesting option to MoarVM's configure script: 12:53
--use-readline
Disable Linenoise and try to use the system version of GNU Readline
instead.

masak rules in grammars suffer from a systemic problem similar to that in cooperative multitasking: that of a "rogue" player not handing back control to its caller. 13:24
sometimes I find myself having a mental model of grammars that ignores issues related to this.
PerlJam isn't that almost a feature though?
masak for example, I sometimes expect callee rule to understand when it's time to stop parsing, because a caller rule has some kind of stopper. 13:25
I think that's part of what made me upset about strings like "foo { bar("baz") }" once upon a time, because I (partly) have such a mental model. 13:26
PerlJam: possibly. just because I subconsciously assume that that model is in place, doesn't mean that such a model would be preferable, let alone internally consistent.
13:27 kaare_ left
PerlJam kinda sounds like "functional grammars" where a rule { <a> <b> <c> } could be thought of as "call rule a with rules b and c as parameters" (I mean, if things worked this way, callees could "know" about stoppers) 13:28

Mouq It sounds like a grammar that does classical tokenizing, I think...
masak I just find that sometimes that's the expectation I have on my own grammars, before reality sets in.
Mouq: yes, it hints at a "flat" model like that of tokenizing. 13:31
PerlJam masak: right, I understand. I sometimes fall into the same trap. But the way you phrased it made me think of FP
masak PerlJam: it's an interesting notion. by the way, rules in grammars can already take parameters. I don't tend to use that much, but some people have.
PerlJam (of course, saying "callee" in my head sounded more like "collie" and then I was wondering how to work in a pun involving Lassie ... but maybe I'm sharing too much ;) 13:33
Mouq Most of the time it's easier to use a dynamic var than parameters even if the var is only being set from the callee, since it makes it eaiser to refactor and you don't have to worry so much about how deeply nested a parameter will need to be carried
masak PerlJam: I think your pun fell down a well. :P 13:34

I remember Lassie episodes on TV when I was a kid, but I also remember seeing the dog, going "oh, that's Lassie", then changing the channel.
lizmat well, only having 3 channels narrowed down the choices a bit :-) 13:46
[Coke] is reminded by the slow test runs to ||-ize test_summary.pl again.
lizmat also admits not even really remembering any plots, let alone wells
PerlJam From en.wikipedia.org/wiki/Lassie_(1954_TV_series) "Jon Provost called his autobiography Timmy's in the Well! because a well was the one place Timmy never fell into—abandoned mine shafts, off cliffs, into rivers, lakes, and quicksand, but never a well." 13:53

timotimo lizmat has been working on splitting a new class IO::Dir off from IO::Path, in the hopes of getting overheads down, performance up and to reach more clarity. ← does this sound representative of your efforts? 16:44
lizmat (aka no error messages whatsoever, just saying everything is done when nothing was) 16:45
timotimo: well, actually, it goes deeper than that
when I'm done, IO::Path is obsolete :-)
timotimo ah
FROGGS lizmat: maybe remove the CATCH from the panda script
timotimo so IO::Path turns into IO::Dir and IO::File?
lizmat which both consume the IO::Local role 16:46
I also envision an IO::Link (for symlinks)
timotimo how do we represent relative paths we may want to plop onto different IO::Dir instances?
lizmat an IO::PIO (for all IO objects that read / write)
typically, you wouldn't make any IO::Dir instances yourself 16:47
dir() (and its method cally friends) will create them for you
16:47 Alina-malina joined
timotimo what does the P stand for this time? :) 16:47
lizmat I have no idea 16:48
IO::Handle has a $!PIO, IO::Socket as a $!PIO
it is a parameter to many nqp:: functions
timotimo that used to be the parrot IO object
lizmat aha :-)
timotimo i suggest not holding on to that too much
lizmat well, maybe it's time to name it something else then
in any case, all basic IO operations (except reading/writing) will be possible by using subs with just strings 16:49
open() dir() pipe() rename() symlink() unlink() mkdir() rmdir() etc.etc.
gtodd oh
lizmat dir() is the one that returns IO::File/Dir/Link objects 16:50
(unless you ask for strings)
16:50 grondilu joined
timotimo IO::PIO is a role? or a class? 16:50
lizmat a role
timotimo and IO::Link a class?
lizmat yup, for symlinks (although I'm not 100% sure about that yet) 16:51

lizmat and it's not like there are many other people committing at the moment :-(
japhb Sure, but I just meant, you've changed your mind a couple times, and each time pushed the new code to nom, did the deprecations, changed the spec, etc. But it won't be really settled down until the IO code can handle *all* the IO needs, and I have fears that this will cause design changes again -- which hit nom and spec each time.
The work and experimentation are great, I'm just asking if it can go in a branch. And we can add test runs for that branch if need be. I know Travis can do this ... I don't want to speak for [Coke], but it sounds like nothing in his automation would *prevent* such a change. 19:05

lizmat japhb++
but what would automated testing of a branch bring? 19:07
I run a spectest at least 3 times an hour when I'm working
the most important reason is that working in the setting for such a deep part
breaks in interesting ways at interesting moments
japhb Feedback from *another* platform about breakage -- and in theory, we could test against e.g. all of the ecosystem to look for regressions. 19:08
Yeah, working in the setting is a real pain. :-(

FROGGS there are no outstanding rakudo branches
just the panda/reporter and panda/CPAN 19:14
19:14 kjs_ joined
japhb panda/reporter is for your new service, I assume. What's the state of panda/CPAN? 19:14
FROGGS the former can be merged after 2014.11 release, the latter needs more work on portability of NativeCall, Compress::Zlib etc
japhb: it only works on linux x64 so far 19:15
maybe osx, not sure
but since NativeCall has issues on 32bit I can't just ship it with panda
japhb Ah, gotcha. 19:16
FROGGS these are the new deps btw: github.com/tadzik/panda/tree/CPAN/ext
quite a lot :/
japhb Are the 32-bit NativeCall issues some really nasty deep problem, or just a SMOP that hasn't been done yet?
FROGGS somewhere in between I suppose 19:17
I tried twice to fix it, without luck
japhb Woah, yeah, that's quite a bit of new deps, though I understand the reasons.
FROGGS and jnthn++'s upcoming work could help in that area

FROGGS grondilu: the bug is that int should mean 32/64 bits depending on the platform... and it somehow always means 64bits atm 19:28

colomon will go rake leaves until FROGGS is done. ;)
lizmat on the subject of IO specs: this is my current plan (which I have tested and implemented mostly):
1. IO::Spec / $*SPEC is on the way out 19:29
many of the current methods need a $*CWD and a $*SPEC specification
jnthn pointed out that we have a race condition there
since all foreseeable OSes on which rakudo will run use / as a directory delimiter (or at least can work with it) 19:30
we only need / for dir delimiter
the only Win specific thing for which IO::Spec was testing, was Driveletter:/ and //UNC/ 19:31
I think I found a cheap way of handling them as well
the only other things IO::Spec is really doing, is providing sensible defaults for different OSes (like tempdir) 19:33
FROGGS true
lizmat and many path modifying functions
so, long term goal: IO::Spec out of the core 19:34
2. most OS operations work on simple absolute paths at the lowest level
so, if you want to do a dir(), you shouldn't have to make an object of the path first before, only to get the path out of that again to do the operation 19:35
internally, the default of doing a dir, is returning a string 19:36
to easily differentiate dirs from other dirs entries, these strings get a '/' appended 19:37
this also makes it much easier to concatenate a dir with a relative path to get an absolute path
since we need to know whether something is a directory or not, we need to check, and therefore we can encapsulate that knowledge into an object of a different class 19:38
one that shares a lot with the generic file class
all objects returned by dir(), have the same API
except of course, when it doesn't make sense, or is not allowed (like open() on a directory) 19:39
fwiw, it seems that directories being represented with a trailing slash, seems to cause the most woe at the moment 19:40
I think it would be very nice if we could keep that, as it is simple, and a good visual cue whether something is a dir or not
3. IO::Path is trying to do too many things 19:41
19:41 vendethiel left
lizmat it tries to handle local file paths *and* pipe commands *and* connection strings for sockets 19:41
therefore I would like to see IO::Path go as well 19:42
instead, the .IO function (which is the main creator of IO::Path objects, IO::Handle objects before) will create an IOU object

lizmat where was I? ah yes, 3. the IOU class 20:16
in a lot of ways, that will be like the IO::Path of today, except it won't pretend to be doing paths 20:17
depending on the method called on the object, it will do the right thing using the string (and $*CWD when needed) 20:18
so "foo".IO.open( :named )
will do an open( $*CWD ~ "foo", :named ) 20:19

lizmat (to continue) would return an IO::Handle object 20:22
doing "echo Hello World".IO.pipe would do a pipe("echo Hello World") and return an IO::Pipe object 20:23
"localhost:25".IO.connect would return an IO::Socket object 20:24
(not sure whether we want a connect() sub)
4. IO::Handle, IO::Socket and IO::Pipe would be conumers of the IO::PIO role (PIO or some other name indicating the underlying common attribute) 20:26

lizmat 5. all paths are absolute
if you call .relative on a IO::Local, it will take C*WD and match it against the path and remove the part that's in C*CWD 20:37
*$*CWD
.absolute will just return the absolute path verbatim
moritz why?
in other languages, open($filename) works fine for relative file names without any conversions to absolute 20:38
lizmat moritz: and open("foo") will just DTRT
just like other languages
it will take $*CWD of the moment of open and prepend that if it's a relative path 20:39
FROGGS moritz: we absolutify filenames passed to open already
moritz why?
FROGGS correct, so when you change $*CWD one statement later, you still know what was meant
lizmat because $*CWD is volatile in a threaded, async world
moritz oh right, we have $*CWD 20:40
lizmat my previous approach was to keep whatever was given (absolute or relative), and keep $*CWD along as well
moritz which can be different from the OSes idea of the working directory 20:41
lizmat moritz: indeed, the OSes idea of the working directory only makes sense for initializing $*CWD at startup
nothing else

hmmm, might not be related to the VERSION file.... maybe it is about deprecations? 21:28
m: Version.new('') 21:29
camelia rakudo-moar 315ec6: OUTPUT«===SORRY!===␤Start argument to substr out of range. Is: -1, should be in 0..0␤»
lizmat yup
ok, I'll fix that... still
weird that it starts complaining now ??
FROGGS and that we don't get that on our machines 21:30
colomon masak: OMG, just realized lower-bound / upper-bound only ever worked for numbers. sigh.
vendethiel hello, #perl6. 21:31
colomon in my defense, this is some really old p6 code.
FROGGS hi vendethiel
masak howdy, vendethiel
colomon Sept 2010...
vendethiel masak, tired, 'twas a long day. what about you
masak colomon: no matter. I'm halfway through messing up my own binary search now... :)
FROGGS okay... so who do I need to bug about a subdomain of perl6.org?
masak vendethiel: same. but doing nice Perl 6, so I'm not complaining ;) 21:32
colomon masak: anyway, my new binary-search function does exactly what you need, I think. ;)
masak :)
FROGGS [Coke]: do you know who can register subdomains to perl6.org?
21:32 ab5tract joined 21:33 kjs_ left
timotimo maybe if i try again, i'll find that blatantly obvious thing that makes JSON::Tiny slower than it could be ... 21:33
colomon timotimo++ # could really use JSON::Tiny being faster for $work 21:34
FROGGS me too
timotimo well, there's the module that binds some c library
that should have been a prefix:<++> rather than postfix:<++>, colomon :)
colomon timotimo: yes, but it changes how JSON import works (or at least, did so last time I checked)
timotimo that's true
colomon timotimo: I reward effort, too. ;)
21:35 H2O1 left
colomon I mean, I could rewrite the script in p5, too. 21:35
timotimo you'd perhaps write a little "crawler" that'll turn the data that library gives you into a regular perl6 datastructure
colomon but if JSON::Tiny just magically got faster, that would be the easiest solution for me.
lizmat m: Version.new
timotimo what kind of factor are you looking for?
camelia ( no output )

colomon masak: Just updated List::Utils. Now has a binary-search which takes a &test argument, and returns the first index for which the test is false. 21:37
masak: I re-implemented lower-bound and upper-bound in terms of it, which means it has … 22 test cases. Not even vaguely thorough. 21:38
m: 110.log(2) 21:39
camelia ( no output )
colomon m: say 110.log(2)
camelia rakudo-moar 315ec6: OUTPUT«6.78135971352466␤»
masak colomon: thanks, I guess. I'm not convinced my particular generalization of binary search is a net utility for all possible users of a binary search routine... 21:40
21:40 xfix is now known as notfix
masak colomon: having to do a &test like that is a fairly fringe-y case. 21:40
colomon masak: totally not 21:41
21:41 firefish5000 joined
colomon lower-bound and upper-bound are both simple one-liners using the new binary-search 21:41
FROGGS moritz: from the irc logs it looks like set up doc.perl6.org... can you register a subdomain of perl6.org pointing to my server? 21:42
ab5tract colomon: you get to work in p6? 21:43
ab5tract jealous
masak ab5tract: we have openings. 21:44
ab5tract: better grab them quickly, though.
ab5tract masak: wait, what? :)
masak ab5tract: Perl 6. we have openings. if you want to work on p6.
colomon would we have to move to Sweden? 21:46
moritz FROGGS: perl6.org has a wildcard subdomain all pointing to 193.200.132.142; it seems you need a different IP, so all I can do for you is contact the domain owner
PerlJam thinks masak needs to clarify who "we" are. 21:47
masak the Perl 6 team.
btyler_ colomon: if you mean the JSON::Jansson binding I wrote, I ended up adding an option to import it into a regular data structure
dalek kudo/nom: 8a4b9e8 | (Elizabeth Mattijsen)++ | src/core/Version.pm:
Make Version.new("") not die
masak (but, yeah yeah, Edument is hiring, too...)
:P
colomon btyler_: ooooo
btyler_ which crawls the jansson structure, much like timotimo mentioned
lizmat waits for Travis again
btyler_ anyways, if you have specific requests, leave an issue, I'd be happy to jump back into that now that the dust is starting to settle for me in .nl 21:48
note that the conversion from jansson-->perl 6 structure sucks up a fair bit of time, so the advantage it enjoyed over JSON::Tiny is likely rather smaller 21:49
FROGGS moritz: I'm not yet sure if I want cpandatester.perl6.org or testers.perl6.org pointing to 85.25.222.109
moritz FROGGS: IMOH 'testers.perl6.org' is cleaner
*IMHO
timotimo btyler_: oooh, way cool :) 21:50
colomon timotimo: btw, if you'd like profiles of JSON::Tiny reads…. ;)
FROGGS moritz: that's what I think too
timotimo colomon: sure, go ahead :)
masak colomon: fwiw, here's the binary search I ended up with. gist.github.com/masak/abdbddcb25983fbd8935
FROGGS I still can register cpandatesters.org if I want to :o)
masak colomon: it seems to work now.
lizmat FROGGS: why not? 21:51
FROGGS lizmat: why not what?
lizmat register cpandatesters.org 21:52
FROGGS I dunno
moritz FROGGS: should I send the mail? 21:53
FROGGS moritz: ohh yes please
lizmat: ok, I ordered cpandatesters.org 21:55
if someone wanna be a cpanda tester: checkout panda/reporter, rebootstrap, run: PANDA_SUBMIT_TESTREPORTS=1 panda --exclude=Panda smoke (or just install dists while that env var is set) 21:59
and then the reports pop up here immediately: 85.25.222.109/recent
colomon FROGGS: "This webpage is not available" 22:00
afk # small children jumping in leaves
FROGGS eww
masak no, dangit. I want to find the last Keep! :/ 22:01
masak .oO( user requirements always change. even when you yourself are the user ) 22:02
FROGGS colomon: looks like the service dies for certain requests (via browser), but respawns and happily receives reports
weird that is

lizmat we still don't know where the empty Version string came from :-(
moritz FROGGS: is there an IPv6-address too?
lizmat so in a way, this was treating the symptom, not the cause :-(
FROGGS lizmat: this can also come from the os version
moritz: I'd have to set it up, but it is able to do ipv6 22:04
moritz FROGGS: let me rephrase. Should I ask for an AAAA-record right away? 22:05
FROGGS cpandatesters.org/ should now work for some of us :o)
moritz: I have no idea
PerlJam now I can't stop seeing cpan-datesters 22:06
FROGGS moritz: does that disallow ipv4?
PerlJam: :P
'sters
moritz FROGGS: no; but if you have no idea, it's better not to advertise a v6 address

tgt I'd have expected @a div $n to be exuivalent to floor(@a / $n)
timotimo huh, weird. we're doing getlexperinvtype_o for $?CLASS in nqp apparently? 22:20
PerlJam "exuivalent" should totally be a word
tgt :D Not sure how I typoed that. 22:21

a la arrays in scalar context in p5 22:23

that's what rakudo implements.

hagiri TimToady, hello man 22:26
ab5tract tgt: honestly i don't think @a / $n should be coercive either
hagiri hello all ;)
ab5tract it seems easy enough to write @a.elems / $n for the coerced behavior 22:27
dalek ake: 5f9404b | (Arne Skjærholt)++ | src/Snake/ (2 files):
First pass implementation of list literals.

Not very useful yet though, as we don't yet handle variables, which means for
  loops aren't happening yet.		 22:28
ake: 430570e | (Arne Skjærholt)++ | src/Snake/ (2 files):
Rudimentary variable and assignment handling.
ab5tract too much contextual twiddling can only lead to trouble
tgt I'm happy to write +@a div $n. I was just changing some code from floor(@a / $n) to use div and was surprised. 22:31
ab5tract tgt: i agree, it is a bit surprising. that's why i'm uncomfortable with the @a / $n coercion :) 22:33

timotimo FROGGS: why does 85.25.222.109/recent take forever to reply? 22:40
FROGGS timotimo: I'm not sure... I cannot fetch a single site right now :/ 22:42
timotimo OK
my very first optimization attempt resulted in no improvement whatsoever
hm. 22:43
maybe i should be reading a json file that takes longer than a second to load in order to profile stuff
FROGGS timotimo: looks like too many reports are fetched from database for the /recent page... so either perl6 or DBIish has a problem there 22:44
