dalek Heuristic branch merge: pushed 18 commits to panda/pod-installing by tadzik 00:00
nda: 551cdc5 | tadzik++ | / (4 files):
First attempt at installing pod aside .pms and .pirs. Tests work, modules not really
panda: 395943c | tadzik++ | ext/File/Find.pm:
panda: Merge branch 'master' into pod-installing
00:00 dalek left
tadzik eh, I'm a dalek-murderer today 00:00
00:01 dalek joined, ChanServ sets mode: +v dalek
diakopter dalek: wb 00:01
japhb_ dalek needs to be taught not to suicide, either by spacing out the commit reports, or by cutting them short even when they don't meet the threshold of "Heuristic branch merge" 00:05
dalek c: e64715c | tadzik++ | META.info:
Add META.info
diakopter japhb_: it has a bit of flood prevention built in; it was based on the botnix framework
japhb_ nodnod 00:06
Though it seems to need some tuning (or is there special dispensation we can get from Freenode for it?)
diakopter since my first iteration though, sorear has redone it completely at least once
dalek osystem: 27e7687 | tadzik++ | META.list:
Add p6doc
tadzik yeah, I'm quite satisfied with panda now :) 00:07
maybe not quite code-wise, but at least feature-wise
japhb_ Good! 00:08
What do I need to do to test your latest changes (the doc stuff)? Or are you ready for that?
tadzik it's all in master
I went full hardcore :)
japhb_ heh 00:09
tadzik panda install p6doc should work now
and then 'p6doc Str' or so
japhb_ So need to pull and build rakudo, then run reboostrap.pl from panda, and then panda install p6doc?
tadzik yep
japhb_ OK, that first part is going to take a while. ;-)
tadzik japhb_++ # testing my mad creations :) 00:10
oh, you need to install p6doc with --notests
it fails some
japhb_ tadzik++ # mad creations :-)
OK, got it
BTW, does one need to (in general) pull panda before running rebootstrap.pl, or does it download a fresh copy of panda to install in ~/.perl6? 00:11
(I know the modules it needs are bootstrapped locally, I'm wondering about panda itself) 00:12
Although I guess it would be silly to pull a new copy of just panda, it might need new copies of the dependent modules
nm
tadzik japhb_: rebootstrap.pl uses bootstrap.pl, which uses the local files 00:13
japhb_ yeah, brain fizzle on my part 00:14
tadzik phenny: tell moritz one of the tests in p6doc/t/typegraph.t fails 00:15
phenny tadzik: I'll pass that on when moritz is around.
TimToady well, boarding time, see you on the flip side 00:16
tadzik fly safely TimToady
japhb_ TimToady, safe flight!
TimToady at least it'll be summer if we land in the arctic :)
afk &
tadzik japhb_: any further ideas for panda? 00:18
Aside from windows support existing at all :)
japhb_ tadzik, does this version work under both Rakudo and Niecza? 00:19
tadzik I don't think so :( 00:20
japhb_ That would be a biggie
tadzik colomon's been working on panda-niecza some time ago
yeah, that'd be cool
japhb_ Not needing an external program to fetch the projects list would be a nice item
colomon niecza doesn't have exceptions
tadzik oh 00:21
diakopter wat. news.stanford.edu/news/2010/august/...82310.html you mean radioactive dating could be *way* off if solar activity was pretty different in the past 100k years?
darn, moritz's not around to give physics opinion
tadzik hm 00:22
diakopter linked from /. sorry
tadzik but maybe I could make panda run on rakudo, but compile modules using niecza ;>
japhb_ Being able to see just the installed modules (`panda list` variant showing just installed stuff) without needing to manually look at ~/.panda/state, especially if you can see whether they were installed normally or --notests or such.
tadzik omh 00:24
* omw
japhb_ ?
diakopter on my way?
tadzik japhb_: I have a locally lying getfile.pir, which could work instead of wget
yes, on my way
dalek nda: b37c702 | tadzik++ | bin/panda:
Add panda list --installed, listing only installed modules
 00:26
00:26 bruges left
colomon tadzik: oh! that might well work. can't see any obvious reason it wouldn't... 00:26
00:27 bruges joined
tadzik it may be a matter of switching `env perl6` to point at niecza 00:27
and then explicitely running panda with rakudo
japhb_ Oh, clearly I'm slow to realize my own thought processes today -- In the face of rebootstrap, ~/.panda/state needs to know about --notests invocation, otherwise it will fail to reboostrap. :-) 00:31
00:32 spider-mario left
tadzik oh, indeed :) 00:36
japhb_ tadzik, all working well so far (including panda list --installed, tadzik++ for rapid turnaround!)
tadzik :)
japhb_ I'll see if I can fix that doc test fail
tadzik I'm now fighting Q:PIR and LWP/UserAgent from Parrot 00:37
japhb_ :P
tadzik it used to work. Like, few months ago, and as a standalone pir...
00:37 whiteknight joined
tadzik in file '(file unknown)' line 31400315 00:38
this is totally awesome :)
00:38 whiteknight is now known as Guest66935
japhb_ chuckles -- the test is just wrong 00:39
tadzik I looked at it, but I wasn't sure what's happening there :)
dalek c: db7f995 | (Geoffrey Broadwell)++ | t/typegraph.t:
Fix out-of-date test
 00:40
japhb_ I think he got unlucky and used a type with no explicit parent that actually did have a parent -- which had been missing from the source file early on. 00:41
tadzik is there any up-to-date module using Q:PIR? 00:42
japhb_ W00t! # p6doc installed without --notest, and working
tadzik ...and parrot objects...
\o/ japhb_++
japhb_ Hmmm, I think we have enough real-world Pod documentation to start tweaking Pod::To::* to render more readable stuff 00:48
.oO( Pod::To::ANSI )
tadzik I was considering teaching it to use Term::ANSIColor if available 00:49
japhb_ tadzik, another useful bit for 'panda list' might be showing the source url that something will fetch from (or *was* fetched from, plus perhaps its 'git describe', if installed) 00:51
tadzik something like 'panda info' for everything?
japhb_ tadzik, that might end up being a false economy (because what you need to do to highlight things well when you have pure text versus ANSI codes may be too different), but I can certainly see Pod::To::ANSI inheriting from Pod::To::Text ... 00:52
tadzik well volunteered :) 00:53
japhb_ tadzik, yeah, but in tabular form so we get one line per module (otherwise it will scroll away)
tadzik hm
japhb_ BTW, what does this line in 'panda info Pod::To::HTML' mean?
tadzik why would you want so many info in panda list?
japhb_ "Pod::To::HTML" => "*"
tadzik oh, that's version 00:54
most modules have version set to *
as in "no versioning, disregard"
japhb_ Ah!
gotcha
I meant, a well-used ~/.panda/state might have a lot of modules in it. In 'panda info' format, each one takes 6 lines vertically; displaying them all would scroll. 00:55
So I'm asking for the one-line-per-module of 'panda list', but the detail of 'panda info'
:-)
tadzik hmm 00:57
panda info --short or such?
japhb_ Or 'panda list --verbose' ;-)
but yes
That's what I mean
tadzik so, long story short: you want detailed, but readable list of installed modules? 00:58
japhb_ Yes, but I do like being able to do both 'panda list' and 'panda list --installed'. But I'd settle for something that does just the latter with more detail. 00:59
tadzik okay. Want to implement it? :) 01:01
japhb_ Well, sure, I suppose I could give it a try. :-)

benabik++
thank you
benabik NP
01:10 jeffreykegler joined
benabik I think it's not allocating a scalar or something. Might want to do something like my $ret = Q:PIR and then $ret or die 01:11
tadzik I fixed it with %r = perl6_box_int $I0 01:13
rakudo expects %r to be a perl6 object
benabik Ah, right. Boxing is good.
tadzik aye 01:14
interestingly, it didn't like nqp::p6box_i Q:PIR
benabik Probably because it's doing something between the Q:PIR and the p6box
tadzik yep 01:15
dalek nda: 02eb2a8 | tadzik++ | lib/Panda/Ecosystem.pm:
Use Parrot LWP::UserAgent instead of system wget. benabik++ for pir help
 01:16
tadzik and now panda doesn't need wget :)
benabik tadzik++
tadzik it's one step further from niecza compatibility though

colomon is wishing svn had a "stash" 15:35
shachaf git-svn does! 15:36
colomon yes, but git-svn does not work well for my needs. :( 15:37
moritz swaggadocio.com/post/428927895 the 'tap' method is a K combinator. Do we want that in Perl 6 too?
given that we already have several million methods in any, .tap wouldn't hurt IMHO :-) 15:38
_sri++ for asking
_sri \o/
shachaf I wouldn't really call that the K combinator... 15:39
_sri ruby folks coined the term i believe
leont finds .tap confusing because of TAP 15:40
colomon doesn't look like it would be too hard to implement...
shachaf It's a reasonable method for working with Ruby, but only incidentally similar to K. :-)
_sri it's fun syntax sugar
15:41 cognominal left
colomon if you were purely function, the K combinator would basically be a no-op, right? 15:41
_sri ruby-doc.org/core-1.9.3/Object.html#method-i-tap # the documentation for it btw
colomon *functional
shachaf Well, not a no-op -- it would take two arguments and return the first one. 15:42
It would have no effects, but then again, nothing would "if you were purly functional". :-)
colomon ah, yes. but it wouldn't do anything with the second argument
shachaf Right.
colomon whereas it appears to point of the Ruby version is for side effects 15:43
shachaf (Actually it would take an argument X and return a function that ignores its argument and returns X.)
japhb tadzik, BTW, given what happened when I ran panda after the projects.json was shortened ... I'm thinking reboostrap.pl should back up the state file before rebuilding things. Because if the projects.json is incomplete, the installs after the local boostrap will fail ... but the local bootstrap has already written a fresh state file.
shachaf (It's called "const" in Haskell, and it's not useless.)
(Using K as well as another combinator, S, you can write any function. :-) )
PerlJam Why is it called tap?
pmichaud "tap into a method chain" 15:44
shachaf Hah, that post has a bug, I think.
def logger; @logger || Logger.new(STDOUT); @logger.blah; @logger; end
Er, ||= 15:45
Should become def logger; (@logger ||= Logger.new(STDOUT)).tap {|l| l.blah }; end
Oh, wait.
.blah is just initialization here, so it doesn't matter in this particular case.
pmichaud there have been a fair number of times where I've wanted to invoke a method for its side effects but return the original invocant; we even have a mechanism to do this in PAST 15:46
although it's not nearly as straightforward as .tap :-)
colomon just implemented it for niecza. ;)
I think.
nr: gist.github.com/3371209 15:47
p6eval rakudo efde6e, niecza v19-21-gc86e8e5: OUTPUT«11␤10␤»
colomon that's 10.tap({ say $_ + 1 }).say;
is that the right idea?
PerlJam looks like it 15:48
colomon 's little boy is experimenting with with derailers after 1) seeing a rail one in a museum last week 2) having a big piece break off some Thomas wooden railway track, making a natural derailer for the wooden railway. :) 15:49
if I've got it correctly, it would be very trivial to add to our p6 implementations.
pmichaud are there any arguments involved?
i.e., perhaps &block(self, |$capture) ? 15:50
(just wondering a bit)
shachaf There's another name for it in the Ruby world, apparently: weblog.jamisbuck.org/2006/10/27/min...-returning 15:52

colomon pmichaud: adding |$capture wouldn't actually let you do anything more, it just might make it more elegant, correct? 15:58
moritz also "returning" doesn't fit well in Perl 6, because 'return' is bound to routines, not blocks
PerlJam "tap" doesn't fit well IMHO because is has other connotations. 15:59

PerlJam $logger //= en-passant Logger.new: { $_.datetime_format '%c' } 16:03
(yes, I know the name stinks, but that's kind of what's going on: create this object and while you're at it, do this other thing with it
)
pmichaud .do 16:04
$xyz.do( { block })
moritz $xyz.modify( { block } )
16:04 hoelzro is now known as hoelzro|away
pmichaud modify implies a change to $xyz; makes me think of .= 16:04
colomon likes .do best so far 16:05
PerlJam .btw
colomon .tee
moritz and you do it for the side effects, which are usually modifications
PerlJam: .lol
:-)
pmichaud interestingly, the example given in the ruby docs doesn't modify self :-) 16:06
which is why I'm not so certain of "usually modifications"
colomon moritz: I've got to think the most common usage is going to be simply printing out something.
it would be awesomely handy for debugging long chain statments. 16:07
moritz aye
pmichaud .aside
PerlJam .also
moritz @array.map(...).sort.also(&say).join('|') 16:08
shachaf .btw
PerlJam shachaf: yes, I said that already :)
shachaf Oh, yes.
PerlJam (that's still my favorite too :)
pmichaud .btw doesn't have the 'selfness' implication that I'd want to see 16:09
moritz btw always makes me think of comments in LOLCODE
pmichaud it could also be a metaoperator, similar to .* .? etc 16:10
_sri .mesh
colomon still likes .do 16:11
moritz pmichaud: meta operator on invocation?
colomon though there's something to be see for .also
PerlJam colomon: do Logger.new: { ... } # even if used like this ?
pmichaud well, there's a statement:do that we have to be aware of
_sri .also is neat 16:12
shachaf .don't
To be more honest to the K combinator.
PerlJam shachaf: heh!
colomon PerlJam: maybe there's something I don't understand here, but wouldn't do Logger.new: { ... } create a Logger, pass it a block, and then throw away the result?
pmichaud gee, if it's a k-combinator, then just .k() :-P 16:13
moritz 'do Logger.new: { ... }' is just indirect method syntax for 'Logger.new.do: { ... }'
colomon ah
shachaf Does it go both ways?
pmichaud ...except that there's already a "do" statement, iirc.
colomon pmichaud: right.
PerlJam which is why I don't like .do at all :)
moritz shachaf: the other way (using a sub with method syntax is) 'foo'.&say('bar') 16:14
shachaf moritz: Ah, OK.
moritz nr: 'foo'.&say('bar')
p6eval rakudo efde6e, niecza v19-21-gc86e8e5: OUTPUT«foobar␤»
shachaf .after()? 16:15
foo.after(&say)
pmichaud .apply(&say) is close
colomon oooo, .apply ...
pmichaud but $obj.apply(&block) feels a bit backwards.
moritz .oh-my 16:16
geekosaur futz-with :p
PerlJam .btw is still my favorite (.also is a close-ish second, but doesn't feel right in prefix position) 16:17
Where's a linguist when you need one? ;) 16:18
shachaf .after() or .post() or something is declarative.
"it's still foo, just after we called this procedure"
pmichaud .btw bugs me a bit, btw 16:19
PerlJam we all have our quirks :)
colomon pitches .tee again -- it's unix-y but almost exactly right
pmichaud tadzik++ suggests ".inject"
colomon hmmm 16:20
PerlJam heh, we can confuse rubyists with that one
IIRC inject is like reduce
(in rubyland) 16:21
shachaf And Smalltalkland.
(Well, OK, no one lives in Smalltalkland.)
benabik en-passant?
pmichaud bypass
shachaf .detour
colomon .siding
PerlJam .detour kind of works 16:22
16:22 cognominal joined
PerlJam en-passant is "in passing" like "on your way to the store, stop by the post office" the post office is en passant of the store journey (or something like that) 16:23

[Coke] well, if we had something that auto-updated rc tests, you'd see it in perl6-roast-data when it failed
moritz so we could just write a common wrapper that overwrites $*OUT with something that captures the output instead of printing that
[Coke] we'd need to have a way to mark off RC code in the .t, test its output (or expected result), and a script to pull down new versions of RC code when they changed. 17:01

[Coke] so, there's (ugly) markers to denote which part is the code from RC, there's some boilerplate to save the output, there's our expected output when we run the RC code, and then boilerplate to run the test.
(the hardest part was getting the right text for the triangle. we're generating trailing spaces! ;) 17:24
moritz $output.lines>>.trim-trailing.join("\n") 17:25
