seatek can you coerce class attributes into a certain type, using the attribute definition? 01:13
m: class C { has Num $.n is rw; }; say C.new.n = '5.25'; 01:14
camelia Type check failed in assignment to $!n; expected Num but got Str ("5.25")
in block <unit> at <tmp> line 1
01:14 kliph left
seatek like the signature coersion maybe... (Num(Int)) sorta thang 01:14
i was thinking i'd just do my own accessor methods for the attributes and do it there, using a private attribute 01:16
but it's hot out and i'm so lazy
Zoffix m: class C { has Num $.n is rw; submethod TWEAK (Num() :$!n) {} }; say C.new.n = '5.25'; 01:21
camelia No such method 'Num' for invocant of type 'Any'. Did you mean 'sum'?
in submethod TWEAK at <tmp> line 1
in block <unit> at <tmp> line 1
Zoffix huh
Oh 01:22
seatek: right, no, you can't make a variable auto-coerce (yet)
seatek Zoffix: yeah I tried with TWEAK too. :) all the magic i could think of 01:23
i read in the docs that type coersion like the (Num(Int)) that you can do in signatures will be able to be used everywhere else some day, but didn't know if there was something i was missing on attribute definitions 01:24

Zoffix Well, you can just use a Proxy, but I don't get why it doesn't like me 01:30
m: class C { has Num $.n; submethod TWEAK (:$n) { my $_n; $!n := Proxy.new: :FETCH{ $_n }, STORE => -> $, $_n { }; Nil } }; say C.new
camelia Type check failed in binding; expected Num but got Any (Any)
in submethod TWEAK at <tmp> line 1
in block <unit> at <tmp> line 1
Zoffix Where did the typecheck fail what is it whining about?
01:31 pierre_ joined, pierre_ left
Zoffix Ah, OK 01:31
m: class C { has Num $.n is rw; submethod TWEAK (:$n) { my Num $_n; $ = $!n := Proxy.new: :FETCH{ $_n }, STORE => -> $, Num() $n { $_n = $n }; } }; say C.new.n = '5.25' 01:32
camelia 5.25
01:33 kliph left
seatek Zoffix: :) I think I'll just have it call a method to either set/corece or return the value ;) 01:34
Zoffix m: class C { has Num $.n is rw; submethod BUILD (:$n) { my Num $_n; $!n := Proxy.new: :FETCH{ $_n }, STORE => -> $, Num() $n { $_n = $n }; $!n = $_ with $n } }; say C.new(:42n)
camelia C.new(n => 42e0)
seatek i'll forget all that tomorrow
Zoffix m: class C { has Num $.n is rw; method n is rw { Proxy.new: :FETCH{ $!n }, STORE => -> $, Num() $!n {} } }; say C.new.n = '42' 01:35
camelia 42
Zoffix Though that won't let you set it via non-Num in new 01:36
seatek that's interesting 01:37

seatek i had no idea about Proxy's - thanks Zoffix++ 01:45

shyam_ What are the "Real Perl Programmers" dos/don'ts ?
raschipi Perl 6 has a motto that as long as your boss is happy, it's proper programming. 01:49
shyam_ raschipi: I'm unemployed (NEET). 01:52
raschipi So you're your own boss.
Zoffix shyam_: "write code that's very easy to throw away" 01:56
shyam_ Zoffix: Why is that a good thing?
Zoffix shyam_: because then each part of the program can be easily modifed and extended. 01:57
shyam_ Zoffix: Do you mean modularity?
I'm already doing modules...
Zoffix shyam_: another term I heard in use is "YAGNI" (You Ain't Gonna Need It). Which means just because you can implement 100 features, doesn't mean it's a good idea to do so and you'll likely won't really need them all. 01:58
shyam_ Zoffix: I think that's more of a design pattern, than anything to do with Perl? 01:59
Zoffix shyam_: the suggestion is quite literal: look at any piece of code (a loop, a subroutine, a class, a module). It should be easy to throw it away; both technically and emotionally. The whole "modularity" and "re-usability" and not suffering from featuritis all converge on just throwing code away. 02:00
shyam_: yeah, I guess. I don't think language matters much. 02:01
02:01 raschipi left
Zoffix There aren't any published Perl 6 Best Practices I'm aware of. 02:02
If that's what you're looking for.
shyam_ Zoffix: "One of my most productive days was throwing away 1000 lines of code." — Ken Thompson 02:03
Zoffix :D 02:05
AlexDaniel shyam_: this is not what you asked for, but perhaps you'll find it useful: docs.perl6.org/language/traps 02:08
shyam_ AlexDaniel: Do you know how to do something like this: Char @char 02:10
02:10 Cabanossi left
Zoffix int8 @char 02:10
:)
shyam_ Zoffix: This is the full thing I'm using, and it didn't work: int8 @char=(('0'..'9'), ('a'..'z'), ('A'..'Z')).flat 02:12
02:12 Cabanossi joined 02:14 noganex_ joined
Zoffix shyam_: you don't have to type your Arrays in Perl 6 02:14
m: my @char = |('0'..'9'), |('a'..'z'), |('A'..'Z'); say @char
camelia [0 1 2 3 4 5 6 7 8 9 a b c d e f g h i j k l m n o p q r s t u v w x y z A B C D E F G H I J K L M N O P Q R S T U V W X Y Z]
02:16 noganex left
shyam_ Zoffix: It's parametric, and if it's longer than a single char then it will attract Camelia. 02:17
geekosaur also '0' is not an int8, it is a Str 02:18
Zoffix m: subset Char of Str where .chars == 1; my Char @char = |('0'..'9'), |('a'..'z'), |('A'..'Z'); say @char
camelia [0 1 2 3 4 5 6 7 8 9 a b c d e f g h i j k l m n o p q r s t u v w x y z A B C D E F G H I J K L M N O P Q R S T U V W X Y Z]
Zoffix shyam_: ^ you could do that, but I think trying to stick types all over the place will only lead to frustration :) 02:19
Relevant blog post: rakudo.party/post/Perl-6-Types--Made-for-Humans
shyam_ Zoffix: I heard type-level programming is the best practice? 02:23
Zoffix I don't know what that is. 02:25
:)
Type is not King in Perl 6, as it is in Haskell. Perhaps that best practice applies to Haskel but not Perl 6?
shyam_ Zoffix: There's only one "best" practice. 02:29
Zoffix What is it?
seatek it's secret and powerful ;)
shyam_ Zoffix: I mean, you can't say going east is the best practice for some people, and going west is the best practice for others. 02:32
Zoffix shyam_: it is if the first group of people is traveling using a different method of transportation ;) 02:33
seatek i would drive my car into the sea 02:35
hmm. that's west
shyam_ Zoffix: You can't, because eventually they all reach an obstacle; whether it be the coast, or some other formidable barrier, or just running out of fuel. 02:41

skaji Hi, 04:11
I noticed that with recent rakudo, it takes a lot of time to call non-existing methods.
please take a look at this: gist.github.com/skaji/b597ec5ecef2...46ab53bd30
llfourn skaji: That's strange. Looks like it's worth reporting as bug. 04:14
04:15 AlexDaniel left
ugexe Foo.?not-exists; is still fast it seems though 04:16
llfourn maybe exception handling got slow
skaji for ^30 { try die; } is not slow. 04:17
llfourn, ugexe: thanks. I'll open a ticket in rt.perl.org. 04:19
04:20 pilne left
llfourn skaji: cool. I'd put [PERF][REGRESSION] in the title. 04:21
you can just email [email@hidden.address] fyi
skaji llfourn: I'll put the tags in the title, thanks! 04:22

MasterDuke skaji: i'm pretty sure i know why it's slower 04:46
04:46 gdonald joined
skaji MasterDuke: wow! 04:46
MasterDuke about a month ago, i added a feature where it will suggest methods that are similarly named 04:47
m: say Int.son
camelia No such method 'son' for invocant of type 'Int'. Did you mean any of these?
sin
so

in block <unit> at <tmp> line 1
MasterDuke like so ^^^
llfourn MasterDuke: can we make that lazy? ie only calculate it when .gist is called. 04:48
MasterDuke hm, not sure
llfourn (MasterDuke++ btw that's an awesome feature)
MasterDuke it's happening when the $.message is created 04:49
here: github.com/rakudo/rakudo/blob/nom/...#L155-L205 04:50
llfourn :o we have A StrDistance class? 04:51
is that spec'd?
MasterDuke not really
skaji like github.com/yuki24/did_you_mean ?
MasterDuke there was some discussion about that yesterday in #perl6-dev i believe
llfourn tbh I would be a +1 on including .levinstein or something on Str 04:52
MasterDuke skaji: yeah. we already had it for sub and variables, i added it for methods
llfourn because I find myself needing it all the time
skaji I also think it is nice feature! 04:53
04:53 Cabanossi left
MasterDuke the code to generate the suggestions is not very optimized, since i assumed this would be in a failure path 04:54
llfourn mmm
I don't think .message should be called unless it's actually .gisted
MasterDuke but it people are noticing the slowdown it could be made some faster
llfourn no matter how fast it can become I don't think we want it running unless we are actually producing the error message. 04:55
MasterDuke that would be a bigger change
llfourn would it? 04:56
04:56 Cabanossi joined
llfourn it looks like it's because .throw does self.?message to check if there's a message before installing a default '{self.^name} exception produced no message' 04:57
MasterDuke well, right now Exception.throw calls .message
jinx
llfourn well, my intuition would be to re-work that so the message default is done in .gist instead. 04:58
(actually looking at the code it already does that so it might be dead code anyway?)
MasterDuke .throw seems to call .message it so that it can nqp::setmessage with the result 05:00
llfourn mm but maybe we can just do that in .gist instead
MasterDuke maybe 05:01
llfourn that could be a big win in general for code that catches a lot of exceptions
05:04 khw left 05:08 pierre_ left
MasterDuke well, just removing those couple lines from .throw breaks ~20 spectests 05:10
05:11 pierre_ joined
MasterDuke one problem is you lose the argument to die() 05:12
llfourn that would be expected, unless you get the message at the start of .gist?

Todd_ I just got gobsmacked by github.com/retupmoca/P6-Net-SMTP/issues/16 Were Net:SMTP gives the following error: Type check failed in binding to parameter '@seps'; expected Positional but got Str ("\r\n") Anyone know a workaround? Any way to get git to cough up a prior version? This is kind of urgent as it is affecting a security program.
llfourn hmm I'm not familiar with that codebase 05:49
Todd_ It happened just after installing Fedora 25 updates (dnf upgrade) 05:50
I re-cloned from git and uninstalled and reinsalled with zef. No joy.
llfourn you mean you reinstalled rakudo? 05:51
or the module or both?
Todd_ zef uninstall Net::SMTP 05:52
perl6 -v This is Rakudo version 2017.06 built on MoarVM version 2017.06 implementing Perl 6.c. 05:53
Am I out of date, again?
llfourn no but I can tell you that @seps is a parameter in rakudo not in NET::SMTP 05:54
it was introduced 2017-05-19
Todd_ How do I fix? 05:55
llfourn maybe you can run with --ll-exception and put the output in a gist?
05:55 BenGoldberg left
Todd_ what do you mean? 05:56
llfourn perl6 --ll-exception my_program.p6
if you just want a quick fix maybe go back to an older rakudo like .04 05:57
Todd_ will try 05:59
llfourn Todd_: it doesn't look like a problem with a module. I doubt there's a prior version of the module that works. It looks like a regerssion/change in rakudo.
Todd_ dnf downgrade rakudo Last metadata expiration check: 2:51:02 ago on Fri Jul 7 20:10:02 2017. Package rakudo of lowest version already installed, cannot downgrade it. Error: Nothing to do. 06:01

i just noticed a new behavior and wonder if it's worth a fix: i'm in process of converting a p5 module to p6 and named it the same but with a pm6 extension instead of pm. 11:14
timotimo i sure hope retupmoca can apply my PR soon and toddandmargo gets what they need
llfourn timotimo++ # fixing Net::SMTP 11:15
tbrowder when i use it the p6 prog first find the pm version which causes a failure. couldn't perl6 favor pm6 over pm?

tbrowder so renaming is the way to go in this case? 11:18

llfourn I'd say not having it in the same directory
timotimo if so, you should -I. instead of -Ilib and it will pick up what the provides section of the meta file has in it
llfourn had no idea that was a thing 11:19
tbrowder no meta file, this is a more casual setup, renaming is easy

oh, haha
it doesn't abort when it's found a match

tbrowder yes, it makes it through that step. i have been trying to get the build harness to change the perms on the offending dirs but no luck yet. the default perms i think are set by the debian system (i think they may be new in jessie), so the build system will have to deal with it. 11:38
timotimo interesting
tbrowder a kludge would be to create the complete install dir structure as a first step 11:39
with "ordinary" user perms 11:40
for the acrual install-instdir target i'm using the system install command to create the instdir and copy the ./install dir contents to it. 11:41

tbrowder i found that a r-s higher up in my dirs was causing the default r-s with mkdir. i changed that all the way down and that fixed the perms problem with mkdir. 12:16
however, when root, i still get the error about cannot write!! $*CWD ?? 12:17
i'll go back to a vanilla nom and see how that works for me...see ya'll later 12:19

zengargoyle it could maybe be possible that DBIish is loading a different library that itself requires 'pq'. so like maybe NativeCall is finding the first library and that library is not finding the 'pq' library.... 17:35
Resol Boy I had shared libraries ... back in the good old days when memory was limited and expensive sure, but now, it's always something that doesn't work ...
zengargoyle doesn't really do windows, just thinking out loud.
Resol I always seem to run into these load path, location issues ... never seems to "just work" ... sigh ... I'm done ranting now. 17:36
zengargoyle Resol: i get ya. :) last $WORK put every program/library into it's own directory so futzing with LD_LIBRARY_PATH and wrappers and OMG HELL was the norm. 17:37
Resol Yeah, more than half the battle is getting things set up right! 17:38
17:39 bioexpress left
Zoffix dunno, seems like adding the dir to PATH should've worked 17:40
Did you restart your "command prompt" so it'd see the change?
Resol Yes, I did ... and verified that the directories are in the %path% 17:42
Zoffix *shrug* No clue, sorry. 17:43
Resol: if you figure it out, can you post the steps to make it work as an Issue on github.com/perl6/DBIish/issues/new ? This is really something that should be added to install instructions.

17:51 mingdao left, |oLa| joined
zengargoyle does windows have a 'ldd' like command? it could also be that 'pq' needs another library that 'psql' or other postgresql programs can find and work but p6 can't. 17:51
my libpq has 27 libraries it uses....
17:51 mingdao joined 17:53 cpage_ left
Resol So how do you "find" where things are in Perl6. 17:53
Zoffix What sort of things?
Resol In Unit module DBDish::Pg::Native I see a line: 17:54
constant LIB = NativeLibs::Searcher.at-runtime('pq', 'PQstatus', 5);
zengargoyle were it linux.... i'd write a little p6 script that shells/runs the `ldd /path/to/libpq.dll` and inspect the output to see if all libraries get resolved correctly.
Zoffix constant, eh?
Resol I'd like to have a look at NativeLibs::Searcher
Zoffix Resol: can you try re-installing the module? zef --force install DBIish
Resol But for the life of me, these crazy long, non-intuitive directory names that seem to store modules is baffeling
Zoffix constants are compile time, so that value won't ever change anymore 17:55
Resol Sure ..
17:55 Cabanossi left
Resol That's a grand idea 17:55
zengargoyle oh hahaha.
17:56 Cabanossi joined
Zoffix Resol: as for crazy directory names. The modules are actually precompiled and stored as bytecode. I *think* source is also kept somewhere, but it's not used, as in, if you change it, the behaviour of the module won't change. 17:56
Resol And it continues :
So, I guess I can't do an install without git?

And the source for the Searcher is here: github.com/perl6/DBIish/blob/maste...bs.pm6#L57
Resol Forgive me for being dense, but I'm not understanding this ... 17:58
I've tried both of your suggested zef --force commands, neither work.
Zoffix Resol: how does the second one fail? The one with the URL to a zip? 17:59
Resol C:\tools\fbdc>zef --force install github.com/perl6/DBIish/archive/master .zip No extracting backend available in method extract at C:\rakudo\share\perl6\site\sources\26BEE6DE3D8587782D7BFB CA96F730387710091D (Zef::Extract) line 8 in code at C:\rakudo\share\perl6\site\sources\4B1D5A60B59D9541E13F76E0E2A2D55 0E0144053 (Zef::Client) line 239 in method extract at C:\rakudo\share\perl6\site\sources\4B1D5A60B59D9541E13F76 E0E 18:00

Zoffix heh
Resol It's a real shame ...
this was a fresh install of Rakudo ...
I have a really simply little thing to do ... suck some events out of an event log, and summarize them ... 18:07
Zoffix Yeah, but someone dropped the ball with testing releases on Windows.
Resol figured Perl6 would be a snap to do this ...
What's that old saying about the best laid plans? ;-)
zengargoyle hrm, that zip *does* have a META6.json file... 18:08
Resol Yeah, I can see it there ...
18:09 ChoHag left
Resol Okay so for whatever reason, doing the zef uninstall first allowed the zef --force install to work ... 18:10
zengargoyle try without the --force?
Zoffix Resol: well, I don't have good solutions for you. One of them involves building Rakudo from source. You'll need git and tools (like the stuff that comes with Strawberry Perl 5), but as I've said the Rakudo's release manager dropped the ball and wasn't testing properly on Windows, so I can't guarantee latest Rakudo works fine on Windows. The other alternative is to install older Rakudo Star (2017.01
rakudo.org/downloads/star/ ), but that was before IO refactor and I can't guarantee zef and some more modern modules still work with it
zengargoyle ... or .... uninstall first. :P
Zoffix huggable: star
huggable Zoffix, Estimated Rakudo Star releases for 2017: .01, .04, .07 & .10
Zoffix The third option is to wait a few weeks until Rakudo Star 07 :P 18:11
Resol interesting ... so when the install runs, the pq isn't found:

Zoffix :(
Sucks
Resol So the testing is doing the same thing as my little program ...
So I'm back to not being able to locate that library I guess
Zoffix OK. Good. 18:12
Resol I just need to coerce Windows into finding the library ...
Zoffix Fails on my box too "# DBIish: DBDish::Pg needs 'pq', not found" gonna poke at a bit
Resol and that seems to be in NativeCall right?
zengargoyle find where libraries normally go and copy all the PG related .dll's there.
Resol So I look through that source you provided the link to, and I might get lucky?
Zoffix Resol: yeah. Though I don't see what the paths it looks in for libraries are: github.com/rakudo/rakudo/blob/nom/...veCall.pm6
zengargoyle it probably uses the system's DLL loader (like ld.so on linux) so the paths aren't in p6 or NativeCall. 18:13
Resol So, on Windows I imagine that's going to be registry setting or something then 18:14
Zoffix Says it looks in PATH too: docs.microsoft.com/en-us/cpp/build...cate-a-dll
Resol The output of set which shows all the environment variables doesn't yield anything that looks like a library path
zengargoyle you could maybe place them under master/resources/something and install the dll's into the CUR, but it'd take some "i don't know windows"....
18:15 pilne left
Resol Hmmm ... and I have the path pointing to both the PostgreSQL lib and bin directories, where the libpq.dll is 18:15
zengargoyle does windows stil have a registry? if you haven't already set an env variable to override the defaults, there won't be an env variable to be seen by set. 18:16
Zoffix hehe, DBIish currently has 666 commits :)

Cannot locate native library 'C:\Program Files\PostgreSQL\9.6\lib\libpq.dll': error 0x7e
0x7e is "The specified module could not be found."... What module? :/ 19:25
Resol Hmmm ... odd, since you passed the whole path to native ...
Zoffix Yeah.
FROGGS you're talking about libffi vs dyncall 19:26
Zoffix Well, the "cannot locate" is not exactly accurate. That message is printed when MVM_nativecall_load_lib errors out, regardless of the reason
FROGGS and we use dyncall I think
Zoffix FROGGS: yeah, dyncall
OK. Then yeah, the above should "find" the lib. 'cause the path is just passed to dlLoadLibrary()
It errors out for some other reason
Zoffix gives up 19:27
FROGGS hmmm
Zoffix: what if you chdir to its directory and use the dll name without the path?
19:28 skf left
Zoffix FROGGS: tried that. Same error 19:28
Opened an Issue on DBIish: github.com/perl6/DBIish/issues/95 19:29
C:\Program Files\PostgreSQL\9.6\lib>perl6 -MNativeCall -e "sub PQstatus () is native('libpq.dll') {}; PQstatus"
Cannot locate native library 'libpq.dll': error 0x7e
C:\Program Files\PostgreSQL\9.6\lib>dir libpq.dll [...] 06/05/2017 07:07 AM 183,296 libpq.dll 19:30
I'm guessing libpq.dll has something in it that dyncall don't like
FROGGS unlikely I'd say 19:31
there is nothing to like in such a dll
Resol I get a slightly different error than you do ... 19:32
when I execute that, it says : Cannot locate native library 'libpq.dll': error 0xc1 19:33
Zoffix That code is "%1 is not a valid Win32 application."
Resol I wonder what that error code is referring to?
jdv79 Zoffix: yeah, that fixed the new conc bug
yoleaux 17:15Z <Zoffix> jdv79: I think your segv was due to unpacking in Proc::Async.new (discussed in irclog.perlgeek.de/perl6-dev/2017-...i_14844751 ). I'm about to remove unpacking (mostly 'cause of 10x speed boost) and I think other devs are working on the actual fix too

Resol Sigh ... running on Windows is kind of a PITA for this.
I download gumbo, and install, but it needs XML. 19:56
Zoffix Get VirtualBox and run a linux VM in it?
Resol So I download XML and try to install, but it fails some tests ... a repo.lock operation isn't permitted
Zoffix That's what I'm doing ATM. Host Win10 and Bodhi Linux in Virtual Box 19:57
Resol The problem is that I have to run all of this on a server that's running Windows.
19:57 greppable6 left
AlexDaniel slaps greppable6 19:57
Resol Due to firewalls, etc. etc. etc. I can't just do this on my Mac and access the database remotely.
mst AlexDaniel: btw, we *can* do I-lines but if you can get extra IPs that's probably simpler 19:58
Resol It's got to be a local access ...
mst Resol: this is the point at which I set up a bunch of ssh tunnels
Zoffix Or just merge features into fewer bots :)
mst and hope the network admins don't spot what I've done
AlexDaniel mst: I-lines?
Resol How do yo uget Windows to allow you to set up tunnels?
putty?
mst I do it with the standard openssh stuff 19:59
Resol I *might* be able to do that ...
mst but that's because I run cygwin on all my windows machines
because screw not having a command line
Resol I think though, that the firewalls are set up to only allow Remote Desktop Protocol access to the sever ...
Ah, yes ...
well, I probably can't get cygwin installed :-(
It's a Windows Server 2012 box ... 20:00
mst looks like www.skyverge.com/blog/how-to-set-u...ith-putty/ is doable
I've just never done it
Resol Thanks, I'll look at that and see about setting it up to use the RDP ports 20:01

El_Che hi Zoffix, how has been the response so far of your latest post? 20:50
Zoffix El_Che: 100% positive from outside the Rakudo community. Within, I'd say overall it's been positive. The non-yes voices mostly say it's impossible to change the name. Some say the name doesn't matter. And a few say the change would be negative (by citing past Google search result). Importantly, I've not heard any reasons for why the current name is *beneficial* 21:02
21:02 wigner1 joined, andrzejku left 21:03 wigner left, wigner1 is now known as wigner
Zoffix And the biggest challenge from the comments I see is many people think a name is something you just type when you want to talk about the thing. They don't make the connection that the name carries a lot of perceptions with it. 21:04
In my notes I'm preparing, currently word "concise" shows up to be a good concept to base Rakudo on. "Concise is not code golf. Concise is working smarter, not harder. Concise is having shorter programs because you don't need to do a lot. Concise occurs naturally in Rakudo. Concise is readable. Concise is smart. Concise is writing a program in 5 hours instead of 10" 21:07
But Perl cannot be "concise". Because Perl's idea of "concise" is line-noise and code golf.
And since we're on a subject. A quote from my $work's marketing book I'm currently re-reading: "The way for the leader to maintain its dominance is to address each emerging category with a different brand name [...] Companies make a mistake when they try to take a well-known brand name in one category and use the same brand name in another category" 21:10
With a following example of Volkswagen having 67% market share when they had their Beetle which shrunk to 4% once they trying to use the brand of "small and ugly" to sell cars of all types. 21:11
Sounds a lot like the story of Perl

Zoffix Resol: add C:\Program Files\PostgreSQL\9.6\bin to PATH 22:15
Resol: well, the bin of your postgress install
Resol: Hm. I see you had it above in "C:\Program Files (x86)\PostgreSQL\9.4\bin". Is that the actual path? I have 9.6 pg and I used the 64-bit so on my box it's in "Program Files" (without (x86)) and once I added the bin\ to path, DBIish started being happy 22:18
Well, happy enough for its test to tell me it can't connect without a password, but I assume it works as addvertized 22:19
geekosaur could that then be a 32 vs. 64 issue?
dogbert17 probably 22:20
Zoffix maybe. Resol was also getting a different error code than me
geekosaur windows does not handle 32 bit the same way as linux, in particular if you install a 32 bit package on a 64 bit windows it will run it in a 32-bit container
dogbert17 and it will end up in the (x86) directory
geekosaur and it's entirely possible that trying to load a 32-bit dll in a 64-bit process will fail

Resol So, I see that I can't load 32-bit DLLs in 64-bit code.
And Rakudo Star will be 64-bit, but my install of PostgreSQL is 32-bit 22:54
MasterDuke can you get a 64-bit version of PostgreSQL? 22:55
Resol Perhaps ...
I bet I can get one and then run it in a sandbox ...
The current version of PostgreSQL that I'm using comes "bundled" with a network management application I'm using. 22:56
Funny, it's just been upgraded to the latest / greatest version ...
MasterDuke there's a 32-bit version of rakudo star, but it's a 1.5 years old
