07:50 gcole left
moritz drKreso: do you have libmysqlclient installed? 07:50
drKreso: if yes, that's a bug in NativeCall, not MiniDBI
drKreso I did install mysql libs for ruby?
moritz (and I maintain DBIish, not MiniDBI)
drKreso Yes definitely NativeCall - been compiling it since yesterday (big hurdle for me was that it doesn't detect darwin) 07:51
moritz: So DBIish is in better shape? I thought you ported both (on github) 07:52
DBIish installs fine - when invoking I get same message Cannot locate native library 'libmysqlclient.bundle' 07:54

 08:24
FROGGS ohh well
:o)
drKreso FROGGS: I've been messing with NativeCall since yesterday. It turned out that it was misconfigured fro 64bit darwin… now I finally managed to set it straight, and on the next step I get Cannot locate native library 'libmysqlclient.bundle' (DBIish call to mysql). Do you have any ideas? 08:26
grondilu rosalind's PMCH this one was a nasty trap :/
FROGGS phenny: ask jnthn if it might be helpful to have a libp6cre.so/dll that does NFA? would this be useful for the JVM port or for rakudo@parrot? Btw, I have no idea (yet) what libpcre does, but I'll investigate...
phenny FROGGS: I'll pass that on when jnthn is around.
08:26 gcole left
FROGGS drKreso: do you know where that library is on your disk? 08:27
is it called .bundle? there can be a .dylib too, so maybe nativecall is searching for the wrong file
drKreso FROGGS: /usr/local/mysql/lib 08:28
FROGGS so I guess it is either the library search path or wrong file extension 08:29
drKreso it's .dylib
FROGGS see
drKreso I tried DYLD_LIBRARY_PATH="/usr/local/mysql/lib:$DYLD_LIBRARY_PATH" but no progress
FROGGS drKreso: perl 5 asks gcc for the possible file extension on the current system, and gcc usually reports only one 08:30
drKreso FROGGS - how can I test ?
FROGGS i guess nativecall does the same trick, se there should be a hack in nativecall that tweaks these file-exts a bit 08:31
drKreso oh - ok
FROGGS lets have a look at its source
drKreso I have a feeling NativeCall is not OSX guy, and that is source of my suffering :) 08:32
jnthn that is
FROGGS see this for example: github.com/jnthn/zavolaj/blob/mast...l.pm6#L117
OSX is a always a corner case when it comes to port things to it, they say it is just a BSD but that a lie 08:33
(thinking of fat libs for example) 08:34
drKreso Ok so *VM is ENV variable right? Where is <config> and <load_ext> set? 08:35
FROGGS drKreso: btw, you should be able to specify the full name to the "is native" trait
drKreso ?
FROGGS no, *VM is the virtual machine rakudo is running on, currently parrot
can you gist the code that is failing? 08:36
drKreso gist.github.com/drKreso/5070183 08:37
FROGGS ahh, so you/we have to patch DBIish 08:39
drKreso FROGGS: ? 08:40
FROGGS hold on
see github.com/perl6/DBIish/blob/maste...ql.pm6#L12 08:41
this line tells NativeCall to load libmysqlclient
NativeCall will append the file extension then, using the one given by parrot (which is the same gcc tells you) 08:42
drKreso: can you try that? perl6 -MNativeCall -e ' sub a is native("libmysqlclient") { * }; a() ' 08:44
this should give you the same error message
drKreso Wow, what? I mean it does, but I have no idea on what are you doing there? 08:45
08:47 ObseLeTe joined
FROGGS this line loads NativeCall, and tells it to load the mysqlclient library 08:47
08:47 domidumont joined
FROGGS and now try: perl6 -MNativeCall -e ' sub a is native("libmysqlclient.dylib") { * }; a() ' 08:47
08:49 domidumont left
drKreso what is tho is native? a = load lib? 08:49
Cannot locate symbol 'a' in native library 'libmysqlclient.dylib'
but lib is found 08:50
FROGGS "is native" after the subroutine name is called a trait 08:51
this trait for example applies some behaviour to the sub 08:52
like doing extra things when the sub is getting called
so, we found the lib, but there is no symbol a in it, but thats ok, just was a test
08:53 gcole joined
FROGGS I dont expected it to have that symbol :o) 08:53
so, I'd say we try to fix NativeCall to check for .dylibs too, okay?
drKreso FROGGS: Got it, and how would I proceed on checking .dylibs? 08:55
Oh , after first call, try second and than fail
FROGGS at this point the libmysqlclient.bundle is expected: github.com/jnthn/zavolaj/blob/mast...l.pm6#L119 08:56
I'll have a look at that nqp:: sub
drKreso: I'm not sure, this might be a good place to do that: github.com/perl6/nqp/blob/master/s...#L851-L858 09:00
but I'll have to ask jnthn, because this is out of control for NativeCall then... 09:01
phenny: ask jnthn if he can scroll back to 10 a.m. please? :o) 09:02
phenny FROGGS: I'll pass that on when jnthn is around.
drKreso FROGGS: It looks like a good place
FROSSS: I'll play with it for a bit :) 09:03
09:03 gcole left 09:05 toddr_ left
drKreso FROGGS: One more question, now when I change code, what is fastest way to rebuild. I have a feeling mine is suboptimal 09:06
At least for nqp
FROGGS how many cores do you have?
(cpu cores) 09:07
drKreso 4
FROGGS good
so, after changing that C file within the nqp folder do: make -j4 && make install 09:08
then in the rakudo dir: make realclean && make -j4 && make install
takes about 3 to 4 minutes on my laptop
drKreso FROGGS: Brilliant. BTW I think you guys are completely MAD (In a good way). 09:12
FROGGS *g*
thanks
09:14 X-Scale joined
drKreso FROGGS: I get this in rakudo folder : make: *** No targets specified and no makefile found. Stop. 09:14
FROGGS that is weird 09:15
drKreso Configure again?
FROGGS well, then you have to say that it should use the given nqp, and not clone it again
drKreso i runned configure and it was done instantly - no cloning 09:16
FROGGS ohh 09:17
drKreso CPU is sweating :) All 4 cores :)
FROGGS that is my command after make realclean: perl Configure.pl --with-parrot ~/dev/rakudo/nqp/parrot/parrot --with-nqp=~/dev/nqp/nqp && make -j4 && make install
(I have a batch file for rebuilding)
all 4 cores, -j4 does that 09:18
drKreso I think I will just steal it :0

FROGGS that's how software development works 09:22
drKreso FROGGS :) I guess. One question - I do need to delete site, and reinstall panda, and modules? 09:25

drKreso I am in nqp_dyncall.ops (As far as I can tell this is C). I get char *lib_name = Parrot_str_to_cstring(interp, $2); and in that lib_name I would like to replace ".bundle" with ".dylib".

The test covers a bug I fixed a day or so ago.
drKreso jnthn: STRING * lib_name_alternative = Parrot_str_replace(interp, $2, pos, 6, Parrot_str_new(interp, ".dylib", 0)));
jnthn Wait, what's the 6 argument? 10:47
drKreso jnthn: I have no idea :)
What needs fro be there? Number of chars in repl string? 10:48
jnthn ah, it's the number of characters you want to replace
drKreso So is it zero based? 5 or 6?
jnthn r: say '.bundle'.chars 10:49
p6eval rakudo 40069f: OUTPUT«7␤»
jnthn That number
No, it's not an offset, it's a number of chars.
drKreso So it means start at pos, remove x(7) and put string 10:50
jnthn yeah
drKreso makes sense now that you say it
jnthn FROGGS: On the NFA thing, the NFA evaluator is actually not all that much code, but also its purpose is to calculate a ranking of longest tokens, so it's quite specialized at that. 10:51

the C code is from rosettacode: rosettacode.org/wiki/Longest_common_subsequence
FROGGS can you gist the code of that library?
grondilu no ned for a gist, it's really the exact same as in RC: rosettacode.org/wiki/Longest_common...sequence#C 18:11
compiled with: $ gcc -o lcs.o -fPIC -c lcs.c; gcc -shared -s -o lcs.so lcs.o 18:14
18:18 gcole joined
jnthn grondilu: Odd. Does it happen when handling the return value? That is, does it make it into the C code? 18:18
TimToady does NativeCall have any access to the bitsizes of the actual C types of the calls its making, like off_t, size_t, or time_t? or is it just guessing?
FROGGS TimToady: you have to specify it in perl 18:19
grondilu jnthn: I guess compilation is fine since it ran well with shorter strings.
TimToady which means it will be wrong on a different machine...
FROGGS grondilu: there is a char bufr[40] 18:20
TimToady would be nice to have at least the level of portability provided by C itself...
jnthn int means "machine's native integer", so that one is already covered
FROGGS grondilu: maybe that not enough?
jnthn Yes, having a size_t available would be good too. 18:21
TimToady well, but if we don't know what type off_t maps to, we're kinda hosed
uvtc Oooh. Would be nice if the repl could remember what I typed in previous sessions, so I could up-arrow to reach longer passages without needing to re-type them.
colomon has started using the github app to track what jnthn++ is doing on nqp-jvm when colomon is away from IRC
TimToady seems that info has to be out there somewhere
or debuggers wouldn't work
grondilu FROGGS: of course that's not enough. What's the point of using a C library if it's not for tough jobs 18:22
?
TimToady the basic problem is that using a C library is only half the solution; using /usr/include is the other half 18:23
grondilu really wonders where this 40 comes from.
geekosaur you can get it from the symbol table, but only to a point: you get the size, but not e.g. signed-ness unless it has debug symbold 18:24
nwc10 jnthn: A: "works" on "my" machine
B: Time for that levenstein code was: time = 195.74100017547607
geekosaur and then you have to know how to parse the various kinds of debug symbols out there...
nwc10 is now: time = 181.15300011634827
TimToady well, we can get signedness from the Perl end, if we can get the size from the C end 18:25

grondilu (I thought it was in NativeCall. I feel stupid now)
FROGGS uvtc: "say" that structure? 18:28
uvtc: this calls .gist on it which should do the job (that is the one you can improve on you own classes) 18:29

geekosaur point was more that I don't think an existing perl6 editor mode would have bitrotted much 21:53
uvtc geekosaur: right. Thanks. 21:57

lue I should really start creating my own P6 mode for emacs. I hate cperl.

dalek p-jvm-prep: 1d30e11 | jnthn++ | src/org/perl6/nqp/ (3 files):
Start passing arg list as a parameter.

This is first step in getting rid of the field for passing this.		 23:02
p-jvm-prep: 02001c7 | jnthn++ | / (7 files):
Eliminate callframe args field.

This completes the refactors to argument passing that get things in a state where, once code-gen can provide it, we can start to make use of invokedynamic.

lue S02:744 shouldn't that be Rational[int128,uint64] ? (uint64 instead of what it says, int64) 23:19
TimToady yeah, probably 23:24
lue I'll fix it then. (I thought maybe there was a reason for the switch) 23:25
TimToady no point to storing the sign in two bits
though I'm sure the JVM would be happier with signed types, sigh
lue Mathematically, you'd have to xor the high bits (-3/-5 = 3/5, not -3/5) 23:28

[S02] equivalent Rational for rat64 should have unsigned denominator.

Just like every other Rat and rat in Perl 6.		 23:33
