colomon lue: where are you on the file test operators? 00:20
lue haven't gotten to more of them yet (I should, shouldn't I?)
I need to learn a bunch of PIR for a lot of the file tests.
colomon Hey, it's -Ofun, do what you'd like. :)
don't forget that a lot of that might be a good candidate to rewrite in Perl 6 now. 00:21
lue yes. Should I use the unimplemented stat() ? :)
rakudo: say stat('/etc/passwd') 00:22
p6eval rakudo 37e574: OUTPUT«Could not find non-existent sub &stat␤current instr.: '_block14' pc 29 (EVAL_1:0)␤»
colomon Hmmm... what's the Perl 6 spec for stat look like?
lue I might rewrite it to P6 during the Jerry Lewis (er, Larry Wall) Hackathon.
colomon (or to put it a different way -- maybe the first thing to do is code up a stat as a Perl 6 function, then write the rest of the tests in terms of that.) 00:23
lue yes. Ideally, it returns all file test returns, but in a not-so-quick-to-discern-information way.
colomon hmmm... looks to me like stat might be under-specified. 00:24
at least, you've got to wonder what a "stat buffer" looks like in p6. 00:25
afk # need to get good night bottle ready for the boy
lue as most of the semi-fun stuff in P6 (suppose that's why it's NYI)
colomon Well, there's lots of fun stuff implemented. But yeah, that seems like a big hole in the I/O spec. 00:29
I mean, I can imagine what the stat structure looks like in C, but it really isn't obvious to me how to translate that to p6.
The intent might really be a Buf object, and they're not well-spec'ed yet. 00:30
lue I don't feel like getting in the uncharted backwaters of the unfashionable end of the western spiral arm of the galaxy (er, P6) right now. :) 00:32
I'd rather work on something that's specced. :D
colomon makes sense to me.

colomon what files are they? 00:38
test files, I mean?
never mind. :)
file-tests.t I take it.
TimToady the one I fixed the parsefail in. :) 00:39
lue ...parse fail!? (I didn't test the test file, amazingly) 00:40
TimToady I can hear MJD getting revved up in the back of my head...
colomon you used ' in a ' ' string, I'm guessing.
TimToady got it in one
colomon (I just looked at which lines changed. :)
MJD?
TimToady cpansearch.perl.org/src/PODMASTER/A...cme/MJD.pm 00:41
colomon He was my first guess, but... 00:42
that's quite the module.
TimToady in particular, the DATA section :) 00:43
colomon Bad programmer! No cookie!
TimToady though, interestingly, the word "test" does not occur
colomon If you have `some weird error', the problem is probably with your frobnitzer. 00:44

TimToady I think the most appropriate quote this time is: You know, this sort of thing is amenable to experimental observation. 00:55
colomon :) 00:56
lue: we need to work on your tests some. :D
lue "If it ain't broke, it will be"
lisppaste3 colomon pasted "file-test.t results" at paste.lisp.org/display/95944
lue colomon: what are you saying? Are you saying Bool is wrong? (that's fine. I got * :P ) 00:57
colomon No, I'm cool with Bool. I was going to suggest we add tests to make sure it returns Bool, actually.
but then I discovered the current tests still fail hard, so we probably ought to fix that first.
:)
lue (I looked at alpha code for help, that may be the / of it all...) 00:58
colomon Oh, I think maybe it's looking the root directory for the files rather than the t/spec/S32-io directory.
give me a moment, I think I saw something like that in another test file... 00:59
lue ah, so prefix a ./ then :)
00:59 cotto_work left
lue (not a /. like slashdot would have you believe :) ) 00:59
colomon no, what I'm saying is when you run the test suite, it runs from the rakudo directory, so ./ won't help. 01:00
01:00 yinyin joined
TimToady
.oO(/ fiction)
 01:01
colomon well, hmmm.... slurp.t specifically uses t/spec/S16-unfiled/slurp.t for its test. That seems reasonable.
I mean, just adding a full path.
lue ...relative to the location of rakudo :) 01:02
colomon right.
maybe something like $path = 't/spec/S32-io/'
and then $existing-file = $path ~ "pi.txt"
etc.
TimToady something bothers me about these kinda-absolute paths
colomon that would make it easy to change the tests if the filenames need to change.
TimToady you'd think tests should be self-contained 01:03
colomon well, that's the other way to do it -- write out the files and then delete them when the test is done.
lue but then you'd be dependant on equally low-specced P6 coding :) 01:05
colomon Ah, I think S16-filehandles/io_in_for_loops.t was the example I was thinking of.
It first writes the file, then does a bunch of tests on it, then deletes it. 01:06
colomon is having a hard time resisting giving an inspirational speed about how important the test suite is. 01:08
lue is going to install Infocom IF games (hey, you talked about the frobnitzer) 01:09
colomon *speech
TimToady MJD: I think you are asking the wrong question here. 01:11
colomon lue: if you're not careful, I'll start reworking your test file while you are not around. ;)
lue ah well, I don't care (too much) it's only 20 lines :)
TimToady MJD: A good approach to that problem would be to hire a computer programmer. 01:13

lue a portable USB floppy drive, mind you.
colomon isn't going to mention the Commodore 64 floppy drives he currently has in the storage unit...
lue Although, considering this is a PowerBook G3 Pismo, I could swap my CD drive for a floppy drive if I found one for the Pismo :) 01:24
I can also have two batteries, two CD drives, a battery + zip drive, etc. Look up the PowerBook G3 Pismo for details. 01:25

snarkyboojum yeah
colomon: he's interested in super massive builds
colomon: optimising for a rare use case?
colomon Sure, but it seems like his common case is the real compile doesn't take very long, but looking over the tree takes forever. 02:43
yeah, exactly. at least from my perspective that looks rare.
I mean, everything I build, a no-op build takes a second or two.
a real build generally takes one to ten minutes.
snarkyboojum yeah
colomon seems like his system would be firing off slow builds all the time for me, in the name of saving me a second or two on the fast build. :) 02:44
snarkyboojum colomon: slow builds, as in "normal build time"? 02:45
colomon but maybe I just need to get involved with much larger projects to properly approach it. :)
snarkyboojum: yes.
snarkyboojum colomon: aye

colomon from the comments at hacker news, it seems like the author might be trying to use a fairly slow computer to do huge builds. 02:46

colomon nope. 12:03
I'm still on my couch at home in Michigan.
arnsholt Ah, my bad memory strikes again. Sorry =)
colomon no worries.

colomon I've just been grabbing commented out tests from t/spectest.data and trying them. 12:17
(sorry, got distracted in mid sentence there.)
ruz yep, just found Array.rotate :)
going to test ground in imlementing a method, sounds fun 12:18
colomon anyway, sometimes the tests can be pretty easily fudged to work. 12:19
which is good, then they can be added back to the test suite.
and if you can't, you frequently find interesting bugs to work on.
:)

}
ok +@value == $c && $c, 'pick(*, :replace) is lazy';
}
Can someone explain to me how that tests that .pick(*, :replace) is lazy?
