xenoterracide I'm thinking it's just assignment 01:44
Mouq xenoterracide: Binding 01:47
xenoterracide what's the difference between that and assignment? 01:48
Mouq xenoterracide: It's assignment, but less magical. It binds the variable directly to whatever's on the other side, rather than putting it in a container

xenoterracide Mouq: thanks, hmm immutable pointer... just trying to figure out what to compare this to in my brain 01:56
BenGoldberg The := operator of perl6 is a bit like using the Devel::LexAlias module of perl5. 01:57
But more type-safe, of course.
xenoterracide heh, I've never used that either
BenGoldberg Or putting it another way, $x := $y of perl6 is similar to *x = \$y of perl5, except that it works with any type of $x, not just lexical variables. 01:59
lizmat BenGoldberg: don't you mean Data::Alias ?

btyler hi all. the first example in 'classtut' (with the task dependencies) is broken at the moment. I've found the handful of tweaks needed to get it working again, but I don't have a great 'idiomatic perl6' sense. would appreciate feedback/suggestions: github.com/kanatohodets/doc/commit...d975675afb 02:25
Mouq++'s work on the docs lately got me looking at the issue list for them, this one seemed like LHF 02:26
02:26 orafu left 02:29 raiph left
benabik I'm somewhat curious why you had to make the attributes public. 02:31
02:33 cognominal left
btyler me too. from the baby perl perspective, it just "didn't work" with private ones. I'll put it back in that state to grab the errors 02:33
for the callback, I got 'Cannot invoke this object (REPR: Uninstantiable, cs = 0)' on the line where it gets called 02:34
flipping it public fixed that
well, public + accessor method
I suppose I should try r-j 02:35
hm, indeed, r-m specific bug
02:36 noganex joined
Mouq :/ Weird... also btyler++ :D 02:38
btyler wrong again. cannot invoke this object on r-j as well. not sure what the deal there is

03:48 atroxaper left, atroxaper joined 03:53 atroxaper left
btyler ok, pretty sure the basic issue is that you can't use auto-bind private attributes through adverbs in bless 03:53
so &!callback and @!dependencies were empty and defaulting to the type object that they were initialized as 03:54
that's something you can do with BUILD in the signature, but that gives up the slurpy 'dependencies' and the nice little tree structure for creating the task objects 03:55
03:56 atroxaper joined
btyler Mouq, benabik ^ 03:56
Timbus submethod BUILD(:&!callback, :@!dependencies){ } 04:07
makes it all work
btyler except for the positional params, right?
Timbus i only ran the example
btyler hum, objects.pod said that you can't have positional arguments to BUILD, which is what the example is 04:08
oh, you mean keeping the new
Timbus you keep the new
you just let build set the private attributes
btyler right 04:09
Timbus you dont need any code inside build. its uh, magical
btyler right, saw that in objects.pod
ok, yeah, that seems nicest
04:14 _thou left, [Sno] left

btyler right, I just added some doc to classtut about the BUILD param-attribute binding trick 04:25
is there a way to link to a subheading of another piece of doc?
Mouq L<...>?
L</path/to/doc#subheading> 04:26
I wish there was a better way, but that's the best you can do for now
04:26 _thou joined
btyler ok 04:27
path relative to the originating doc, or relative to the doc repo root?
Timbus i know its not BUILD being magical here. i just feel it would have been more sensible to be more simple. has $!var can init; .. or something. ¯\(°_o)/¯ 04:32
Mouq btyler: Do it relative to root 04:33
btyler Mouq: great, thanks 04:34
Mouq btyler: Stuff gets copied between documents, and its easy for a link to point to the wrong place if its relative
btyler ok. I saw |/ syntax, so I did this: L<objects|/lib/Language/objects#Object Construction>
seem reasonable?

donaldh: I have tried do something like that for IntellijIDEA
10:15 nnunley left
donaldh It should be possible to create a simple jar / OSGi bundle that can reference an existing rakudo installation. That should be useable anyhwere 10:19
The perl6-eclipse-plugin relies on Eclipse-BundleShape: dir so that I can embed the installation and still resolve files off the filesystem 10:21
I think it is possible for an OSGi bundle to unpack into a 'bundle repository' directory but I have not tried.
we could also repack all of the module jars into a single perl6.jar so that they can be easily classloaded. 10:22
many possibilities

lizmat perhaps it would be more transparant, if you could supply the initial state when you create the tap 15:50

EmilPer hello 21:33
FROGGS hi EmilPer 21:34
EmilPer new to perl6
what is the difference between time and time() ?
time() fails, time without () does not and works like in perl5 21:35
FROGGS the latter is a subroutine call, the former could be a term (or a sub call)
and time is defined as a term
EmilPer yes, saw it being called "term" ... what is a "term" ? a reserved word, build-in function ?
FROGGS a term (like in human languages) is a word 21:36
so, 'time' acts like a function, but cannot take arguments for example 21:37
EmilPer ok
FROGGS we could have made it a sub though
EmilPer thank you 21:38
FROGGS you're welcome

vendethiel It's interesting to see how perl has started going out of trend (from google trends) since 2008 23:09

vendethiel oh, but it's cheating a lot. Ruby's first results are pokemon and ruby tuesday. 23:10
python's most searched term is "monty python", by a very long shot 23:11
while for perl, it's only the language itself.
Oh, Now I get a much, much different answer. Perl actually had more searches everytime 'til 2012, and it's a close tie these days. 23:12
Who said perl was dead ? I'm surprised (or impressed) 23:13
BenGoldberg If you don't have a distinctive name, it's hard to use web searches as a metric. 23:14
