manchicken Hopefully I will _finally_ be able to run CI on osx with this... 01:38
Looks like travis doesn't handle CWD the same way with OSX as it does in GNU/Linux. 01:39
Anybody know if there's a way to get Travis-CI to cache your rakudo build?
I keep having to wait for this thing to build Perl 6 before it'll even run my tests. 01:40
timotimo i know only for linux; there's packages for that 01:46
manchicken Well crap... 01:47
This thing won't test because the DYLIB loader can't find the .so that the test needs. It's built, you can see the successful linker call to make it, and it's making it in the right path, but for some reason it just won't freakin' work.
The funny thing is that it works fine on my Mac. 01:49
timotimo i didn't know you can use .so on osx 01:53
02:06 cdg joined
geekosaur it's nto the default but dyld does look for .so as a fallback, as of I think Lion 02:10
badically to make porting easier
manchicken I meant `dylib`. 02:11
geekosaur you do still run into fundamental incompatibilities in the way dynamic loading works, though; if some .so is not being found, first place to look is the RPATH entries in the thing loading it
(or ,dylib)
manchicken Yeah, I pulled the DYLIB path stuff in, but I don't think it's putting it where I expected. 02:12
geekosaur because unlike linux/ELF, it does not assume default locations
manchicken I'm trying a different approach.
geekosaur paths can be relative to RPATH entries (with @rpath tokens) but the default behavior is absolute paths
02:12 function joined
manchicken travis-ci.org/manchicken/perl6-Fcn.../320869746 02:13
titsuki_ manchicken: you can automatically decide that your library should use .so or .dylib by calling $*VM.platform-library-name. (e.g. github.com/titsuki/p6-Geo-Hash/blo...uild.pm#L7 ) 02:14
manchicken This would be a lot easier if it didn't build rakudobrew every bloody time.
titsuki_, I don't think that's my problem. I'm using `LibraryMake` which seems to do that fun for me.
I think it is something just as simple as the path is jacked.
I have a library I'm building that is only for the tests. 02:15
It's not in my META6, because it shouldn't be installed.
02:15 function left
geekosaur you don;t have a path on that at all. that was what I meant by the thing about absolute paths 02:16
manchicken For this Fcntl implementation, I wrote a tiny C program which just appends the machine-specific values for all of the relevant constants to a Perl 6 template file, and then that's your module. To test that, I made a simple library which has a function that compares those values coming from Perl 6 over nativecall to make sure that they make it back OK.
titsuki_ manchicken: ok, I see... ( and you can use it in Makefile: github.com/titsuki/p6-Geo-Hash/blo...file.in#L7 )
geekosaur and... is $TRAVIS_BUILD_DIR == '.' ? 02:17
manchicken Dunno, about to investigate that.
Again, it takes like 10 minutes between runs. Super slow going.
Does anybody know how to cache the rakudobrew build? 02:18
geekosaur (more precisely/usefully is it `pwd`)
02:18 Rawriful left
geekosaur ...or possibly $*CWD but that introduces other complexities 02:18
02:20 manchicken left 02:21 manchicken joined
manchicken Sorry, machine went to sleep on me. 02:25
Does anybody know how to make travis hold on to its perl6 build?
02:31 silug left
manchicken It's been a long time since I had a neat little project to dig into that had any greenfield stuff to do. 02:36
I think I found the problem... 02:46
$ ls -ltr $TRAVIS_BUILD_DIR/resources/lib
ls: /Users/travis/build/manchicken/perl6-Fcntl/resources/lib: No such file or directory
The $TRAVIS_BUILD_DIR is `/Users/travis/build/manchicken/perl6-Fcntl`
So, that path should be there.

Guest49524 how to do `echo test | ./script.p6 a b c`? 11:03
timotimo hey Guest49524 11:04
if you want the script to run with perl6, you'll have to put #!/usr/bin/env perl6 as the very first line 11:05
and of course chmod +x the file
then it should work
Guest49524 timotimo: I have done those, but @*ARGS doesn't contain "test" from echo.
timotimo that is correct, you will have to read it from the stdin. for example slurp() will give you the entire data that was piped in 11:06
there's also lines() which you can loop over to get the data line-by-line
you can play with that with our evalbot, like so:
m: say lines()[3] 11:07
camelia »Ich lösche die Flamm.«
timotimo (we have some example data that always gets piped in; this is from macbeth i think?)
yes, it's the opening act of macbeth
m: .say for slurp.words
camelia »Wann
treffen
wir
drei
wieder
zusamm?«
»Um
die
siebente
Stund‘,
am
Brückendamm.«
»Am
Mittelpfeiler.«
»Ich
lösche
die
Flamm.«
»Ich
mit«
»Ich
komme
vom
Norden
her.«
»Und
ich
vom
S…
timotimo the tiny ␤ symbols replace what used to be a proper newline that the program outputted 11:08
Guest49524 `say @*ARGS.perl;` ...that will work for `echo test | ./script.p6 a b c` to get ["a","b","c"] 11:12
`say slurp.perl;` ...that will work for `echo test | script.p6` to get "test\n"
but can you get both "test\n" and ["a","b","c"] ? 11:13
from `echo test | ./script.p6 a b c`
timotimo sure, how do you want it to look, exactly? 11:14
Guest49524 IDK? I guess just store them into separate variables?
timotimo well, the arguments are already in a separate variable, so you can just "my $all-data = slurp()" 11:15
Guest49524 slurp() tries to access "a", "b", and "c", as files? 11:16
timotimo oh! 11:19
sorry, i should have tried it locally
of course, that's the argfiles trick
you'll actually need to refer to stdin in this case: $*IN.slurp
11:22 psychoslave left
Guest49524 how do you check if $*IN is empty? without `echo test` being piped in it wants user input 11:26
11:30 Zoffix joined
Guest49524 IO::Handle<IO::Special.new(what => "<STDIN>")>(opened, at octet 0) 11:31
I think it's the "octet 0" part?
timotimo no, that just means the file pointer is at the very beginning
Zoffix Guest49524: no direct way, but you could check if it's a TTY: .t and .slurp.say with $*IN
Guest49524: no direct way, but you could check if it's a TTY: .t or .slurp.say with $*IN
timotimo "tty" should be searchable in the docs, IMO 11:32
Geth doc: 4c01cd8253 | (Zoffix Znet)++ (committed using GitHub Web editor) | doc/Type/IO/Handle.pod6
Add `tty` as index marker for .t method
 11:34
synopsebot Link: doc.perl6.org/type/IO::Handle
timotimo thank you! 11:35
11:42 konsolebox left
Guest49524 my $args = @*ARGS.perl;my $pipe;.t or $pipe=.slurp with $*IN;$pipe.say;$args.say; 11:43
what about prompting after that?
and for some reason $args has to be before $pipe but that is fine I just do not know why 11:44
timotimo you mean asking the user to input something on the terminal?
Guest49524 yes
timotimo then you can ".t and $userinput = .slurp with $*IN" 11:45
the ".t or ..." means "execute the thing on the right if it ($*IN) is not an interactive terminal"
and ".t and ..." means the opposite, i.e. "only do the thing on the right if it is an interactive terminal" 11:46
11:46 setty1 left
timotimo you can use "prompt" instead of .slurp there, that will also let you pass a little piece of text to display to the user 11:46
11:48 konsolebox joined
Guest49524 that only works for `./script.p6 a b c` ...not for `echo test | ./script.p6` 11:50
11:50 itaipu joined
timotimo yeah, you can't ask the user for input after you piped something in 11:50
Guest49524 not ever? 11:51
timotimo well, you *can*, but you'll have to do something like "open('/dev/tty', :rw)" and interact with that directly
Guest49524 what about subshelling?
timotimo probably :w, :r actually 11:52
not :rw
echo "input" | perl6 -e 'say slurp; my $tty = open("/dev/tty", :r, :w); $tty.get.say'
this outputs "input" and then you can type something in manually and it'll echo it
i'll be AFK for a bit now
Guest49524 thanks! 11:59
12:01 pmurias joined 12:07 Zoffix left
geekosaur what do you mean by subshelling? 12:12
also you seem a bit confused about how things work
you piped in, therefore you replaced the terminal as standard input with something else 12:13
Guest49524 shell "perl6 -e 'prompt \"query? \"'"; 12:24
but how to get the prompt?
12:29 xcm is now known as Guest47718, Guest47718 left

12:30 xcm joined
Guest49524 docs.perl6.org/routine/run.html 12:31
timotimo Guest49524: the prompt sub returns the text the user inputted 12:32
Guest49524 not from shell() though? 12:33
timotimo no, but you can get that with qx and qqx quoting constructs if you want
Guest49524 true 12:34

jnthn Those shouldn't really be in user-facing docs; they're just proposed things for future Perl 6 versions at this point. 12:54
That may happen or may never happen.
timotimo when perl6 is "finished" it is dead 12:55
araraloren_ such as `goto` ?
Guest49524 Real programmers can write assembly code in any language. 12:56
jnthn It's like asking "when will JavaScript/C#/Java be finished", and the answer is pretty much "when nobody cares to improve them any more" 12:57
Like Perl 6, they all exist in a current useful state, and all have ideas/plans for the future. 12:58

russt1 playing with rakudo and I notice that -x -S command line args are gone from perl5. any work around for that? 22:03
moritz never used either in Perl 5 22:08
russt1: if they are useful, you could contribute a patch that implements them in rakudo 22:09
russt1 possibly, where would I do that? 22:10
22:11 Zoffix joined
russt1 I'm just learning about rakudo (in fact reading your book about perl 6 regexes I think :) 22:11
Zoffix FWIW they look pretty mental. Perhaps we should discuss whether we want them in the first place before making any patches?
russt1 I think if you are Lenz
moritz russt1: I am :-) How do you like it so far?
Zoffix And with `-x` perldoc perlrun says you'd indicate end with __END__ but we don't have an equivalent of it 22:12
russt1 I like it so far except I was trying to port my portable startup system for perl5 to perl6 and am missing those two args...
moritz what do you use it for? On Linux, I just use a shebang, and on Windows you can register a file extension 22:14
russt1 if [ $# -eq 0 ]; then exec perl -x -S $0; exit $? ; else exec perl -x -S $0 "$@"; exit $? ; fi
#!/bin/perl -w
the -x discards lines until it finds the #!perl pattern
moritz but why? 22:15
do you often run "bash myprog.p6"? 22:16
russt1 trying to remember why, wrote this code a long time ago when I had to run on numerous unix systems plus mks shell in DOS 22:19
geekosaur iirc we do have __END__ by abusing pod6 22:20
and the reason for -x and -S is basically to work around systems without shebang support
I *think* we can safely put that one to bed
russt1 the main feature is for the perl interpreter to skip the shell preamble
Zoffix Yeah, the =finish block, but the speculations say "Anything in a source file after a =finish is always treated as Pod.", and you can embed proper Perl 6 code in Pod, which makes it unsafe as a "discard everything after it" feature 22:21
(this isn't implemented properly yet ( RT#127213 ), but still)
AlexDaniel is there an equivalent of that in ruby or python or in anything else?
synopsebot RT#127213 [new]: rt.perl.org/Ticket/Display.html?id=127213 [POD] after =finish isn't picked up in $=pod
Zoffix Relevant speculation, which confusingly does list =finish as equivalent of __END__ design.perl6.org/S02.html#Double-u...core_forms 22:23
Oh wait, not confusingly. In Perl 5 you can stick pod after __END__ too
But you can't run stuff with it

russt1 re: why use shell logic to establish perl env, it was so I could have multiple path environments on the same machine. one can now use #!/bin/env for that. The -S was to get perl to look for the actual script in $PATH. 22:31
teatime russt1: if you want maximum portability, use /usr/bin/env 22:32
russt1 the prlskel prog I wrote then uses $0 to load a perl library in a path that I could control and that has a main, and would execute that. features in prlskel establish a debugging env. among other things. 22:34
what would be the modern way to do all that? 22:35
I guess I could write a wrapper for the perl6 wrapper that would create a tmp file with the pre-amble removed or something. 22:36
I looked at the perl6 wrapper and I gather that it loads a byte-code file which contains the actual interpreter. 22:37
moritz that's correct 22:39
russt1 mosdef not interested in using a poddoc hack for such a simple feature.. :) 22:41
