[Coke] If so, why do we even have that option? :) 00:15
00:15 skids joined
timotimo because if you don't have inline::python, we still want you to have syntax highlighting 00:15
oh, maybe the doc build would be a good opportunity for nine to optimize inline::python 00:16
[Coke] we already require a few modules. doesn't seem like a big deal to require one more.
timotimo though i fear it's probably only a very few calls that are drowned out by perl6 work time
00:18 unicodable6 joined
[Coke] yay, it finished. 00:20
timotimo yay 00:24
00:25 canopus joined
[Coke] ... and search didn't seem to pick up on my changes. hurm. 00:28
timotimo is that perhaps a separate step?
[Coke] hurm. Inline::Python install fails for me, cannot find pyhelper.c:1:10: fatal error: 'Python.h' file not found 00:30
timotimo ah 00:31
install python-dev or python-devel
00:33 eyck left
[Coke] nosuch package on macports. swear i had this working at somepoint. (there are many py-*-devel packages. no idea which one is right) 00:34
timotimo does macports have something like "apt-file" or "dnf provides"?
00:35 eyck joined
geekosaur port provides 00:36
[Coke] guessing, "which port provides this executable I'm looking for"?
geekosaur but only for installed ports; variants make the problem of uninstalled ports rather difficult 00:37
TimToady
.oO(Duke Nukem Forever provides?)
timotimo well, apt-file and dnf provides work based on file-per-package lists they download separately
geekosaur (debian and fedora ship prepopulated databases generated for every installable package. variants change what files a port can install, so the equivalent file is rather large)

AlexDaniel yea, I have fonts-noto-mono installed 02:34

🙋
AlexDaniel thowe: compose key 02:41
I have a custom keyboard layout, so yes, I have added some commonly used characters there 02:42
but most people use compose key for everything
thowe not even sure what "compose key" means

AlexDaniel thowe: you make it sound like alt is the only key on your keyboard :) 03:08
thowe: for example, you can use caps lock as a button for your compose key
thowe I think what I would want to do is probably map the Windows button. I don't use it for anything else. 03:09

TimToady that's what I do 03:14

ZzZombo thowe ^
thowe so, ^methods doesn't return a list of names, it actually returns "methods". Method objects(?) 04:15
ZzZombo yes
thowe ah ha... I come from a Ruby world once upon a time, so I wasn't quite ready for that. That's next level. 04:16
is >>. a special operator on Method? 04:17
ZzZombo well, to be pedantic, it returns a List of methods.
no
it is a generic operator called hyper operator
04:17 pierre_ left
thowe looks like it might be iterating(?) 04:18
ZzZombo basically performs actions on all members of a list, and returns results in order
so here, I tell it to iterate over the result of ^methods() call, call .name on it and the results of all calls are then returned in another list. 04:19
s/on it/on each item/ 04:20
thowe yeah, I got that. Nifty.
Kinda like .each in Ruby I guess.
wow, there's a lot of hyper operators. 04:21
I guess I know some of these already though. I think the term "hyper operator" is just new to me. 04:22
I'm also not reading the page right, so don't mind me... 04:23
04:24 pierre_ joined
thowe what makes something a "Hyper" operator? 04:25
is it an operator on an operator? 04:26
ZzZombo yea, it applies another operator 04:27
thowe I probably shouldn't annoy the channel with stuff I should just be reading up on. Sorry for the noise.

MasterDuke ZzZombo: are you on windows? 04:40
04:40 Actualeyes joined
MasterDuke well, assuming you are, are all the paths in the output of --ll-exception non-windows? or just some? 04:56
ZzZombo Yes 04:58
they look like "C:\rakudo/share/perl6/runtime/CORE.setting.moarvm"
04:58 aborazmeh left
ZzZombo note the first separator is Windows-like, while the rest are not. 04:59
oh, user files properly use only '\'. 05:00
so it affects only internal files.
there is also no consistency in paths on the beginning of strings, I was talking earlier about paths in parentheses: 05:02
from src/Perl6/Compiler.nqp:27 (C:\rakudo\share\nqp\lib/Perl6/Compiler.moarvm:command_eval)
from gen\moar\stage2\NQPHLL.nqp:1508 (C:\rakudo\share\nqp\lib/NQPHLL.moarvm:command_line)
and there are instances of mixed separators as well. 05:03
MasterDuke some parts of those paths are kind of hard-coded, some are pulled from the filesystem 05:05
05:05 awwaiid left 05:06 awwaiid joined
MasterDuke and a bunch of the code is from NQP, which i don't believe has as much OS-awareness as Perl 6 does 05:06
ZzZombo well sure we can decorate the paths but only in the output.
MasterDuke could you rakudobug it? 05:07
ZzZombo Yes.
MasterDuke cool. i'll try and look into it, but it would be good to have in RT in case it slips my mind 05:08

seatek different class isntances are supposed to have different scope though 05:30
that's what makes it unexpected 05:31

I know Rakudo star currently says the JVM stuff has issues and I figured I'd see if I could help with them. Even if it is by tracking down bugs.
Zef fails with "Serialization Error: could not locate static code ref for closure" 09:49

arnsholt I think "say (1..*).grep(* %% 2).map(* + 2)[^10]" and "((1..*).grep: * %% 2.map: * + 2)[1..10]" are different
The latter is equivalent to "((1..*).grep(* %% 2.map(* + 2)))[1..10]

CIAvash xtreak: "take" should be used with "gather" docs.perl6.org/routine/take it doesn't do what you think it does AFAIK. 10:17
arnsholt Using take outside of a gather should raise an exception 10:18

scimon zef build outside of rakudobrew failed with the same message. Trying with --ll-exception now 11:02
So it looks like it's the load_module code which would match with the comments in the Rakudo Star about JVM not doing modules... 11:04
babydrop During last release there were JVM issues even on nqp level, so .... 11:05
Works fine on the much better supported MoarVM tho.
And as much as I want Perl 6 to succeed the JVM backend is not a "viable option" for any boss IMO. 11:07
scimon Sigh. 11:08
babydrop :)
scimon Mine are wedded to the JVM and think it's the best thing since sliced bread.
I foresee one of two annoying options.
babydrop We've a bit of a shortage of JVM volunteers. The ones we have can only do so much with their time. 11:09
scimon Well I can try and help. Might take me a while to get up to speed. 11:10
psch ++scimon 11:11
babydrop scimon: that would be awesome.
scimon Not sure how much help I'll BE. I'll start noodling around. 11:12
babydrop scimon: we also have #perl6-dev the couple of JVM folks who can give you hints are psch and bartolin
psch jnthn++ to most likely, as well as arnsholt++ 11:13
s/to /too/
11:13 xtreak left
psch tbh, maybe shifting towards at-least-installing-modules might be reasonable for me instead of prodding at jvminterop almost exclusively... :) 11:13
scimon Being able to install the module installer would be nice :) 11:14
right now I should do some dayjob as the sprints started. 11:16
(Joined perl6-dev going to lurk for a while) 11:27
babydrop Would be sweet if someone took a gander at failing JVM nqp tests :) They're kind of a pain in the ass, because we don't have a fudger in nqp and Rakudo's automated release system was built on the assumption that nqp tests always pass :) 11:28
psch guesses that's new tests again and we just never noticed that the jvm fails them :/ 11:29
babydrop at least some of them definitely yeah
scimon goes off to read nqp stuff. 11:30
psch scimon: did you find the edumentab slides? those are pretty great 11:31
scimon I have now.

ZzZombo I know about ^, and it actually makes sense and is consistent, but the m(1) form is dumb. 13:52
13:52 AlexDaniel joined
psch it makes the same amount of sense and is similarly consistent... 13:53
ZzZombo no. It's customary to put the invocant ina special place, like $foo.bar or $foo: bar. But in bar($foo) it gets lost as an argument, and can be confused with a sub call. 13:55
babydrop um.... It *is* a sub call 13:56
psch ah, appeal to tradition
well, if that's your argument vOv
ZzZombo ugh, should I take that as methods and subs are intechangable, so you can just use one as the other? 13:57
babydrop ZzZombo: they're both Routines, yes
psch they're not completely interchangeable though
babydrop ZzZombo: I wouldn't say "interchangable," but you can use subs as methods

13:58 aries_liuxueyang left
psch methods are sorta like subs but more OO-friendly 13:58
ZzZombo good try?
psch so, they give you a few OO things 13:59
like allowing an invocant marker and binding a lexical 'self'
also they add themselves to a method table on a object which is why we need the & in $obj.&sub
because that means "look for the code object lexically, not in the method cache" 14:00
in a way *handwave*

ZzZombo anyway, let's go back to the original topic. 14:03
what's wrong with that code?
babydrop .tell [Coke] advent post problem: twitter.com/mcreenan/status/804320288921907200
yoleaux babydrop: I'll pass your message to [Coke].
psch probably something about what's bound to the invocant and where it looks for private methods
babydrop I guess that's what timotimo was trying to fix... 14:04
ZzZombo but the invocant is the right object, the reason must be lying deeper. 14:05
babydrop ZzZombo: a wild guess would be the reason is how private methods are looked up. 14:06
I mean, you can't have multi private methods, for example either.
And normally, you'd have to specify what class the private method is from, unless it's from current class and there ain't a current class in that case
ZzZombo what do you mean no current class? 14:07
babydrop ZzZombo: well, that method is not defined inside any class {}... It's "detached method" or wahtever we call it
14:07 cdg joined
ZzZombo I add it via ^add_method(). 14:08
It's inside the class since then.
psch ZzZombo: so, at runtime
ZzZombo: which proobably makes stuff weird too vOv
babydrop ZzZombo: but normally you just give add_method a code block, not a detached method, don't you?

ZzZombo: you're trying to call a string as a sub. Not sure what magic you're expecting there. 14:35

jnthn Yeah, we could catch and complain at compile time the quoted case too 14:46
Unless the intent was to make self!"A::$foo"() style things work
But we don't try to do anything like that today 14:47
And I guess maybe shouldn't 14:48
Making self!A::("foo")() work would probably be the consistent way 14:49
14:49 bazzaar joined
jnthn Calling privates from the outside is probably best done through the MOP though 14:50
Which is the "official" mechanism to defeat the compiler's enforcement of privacy :)
ZzZombo I'd be fine just if somebody could tell me why somehow it ends up looking for the method it Perl6::Metamodel::PackageHOW instead of ClassHOW, in my case, as it's clearly what the object is inside the handler method.
14:51 wisti joined
ZzZombo I already ended up using ^find_private_method, so I don't really pursue the issue. 14:51
s/it/in/
jnthn ZzZombo: Oh, that's easy: it just takes the current pakcage you're in to qualify the private method call 14:52
And if you write your method at the top level, you're in the GLOBAL package
It's a static, not a dynamic, decision, since private methods are not virtual 14:53
By definition :)
That's the reason why stuff like:
ZzZombo A better error handling should suffice then. I've spent the whole day banging my head against it.
jnthn m: class C { method !xx() { }; method y() { self!x } }
camelia rakudo-moar 843a6b: OUTPUT«5===SORRY!5=== Error while compiling <tmp>␤No such private method 'x' for invocant of type 'C'␤at <tmp>:1␤------> 3C { method !xx() { }; method y() { self!7⏏5x } }␤»

Yes, agree the error isn't good

[Coke] the doc build modifies html/css/style.css 15:17

guessing this isn't happening in prod, since it's adding the external-link icon that I see everywhere locally but not on the site. 15:18
babydrop :/ 15:19
IIRC it'd modify it only if you start the dev web app
Well, "modify"... It merelly converts asset/sass/style.sass to that file
[Coke] yes. but it shouldn't be doing that. 15:20
(and, ideally, local and the dev site should be using the same toolset, but that's a different issue.)
babydrop Right, the build should generate that file instead of it being stored in the repo 15:21

jnthn It does it twice because the past-path binder doesn't know how to produce decent error messages, so upon a bind failure it just re-runs the bind through the slow-path one that does. 15:33

There goes my carreer of absusing subsets then

ZzZombo yes?
babydrop moritz: kyclark confirmed it will be :)
timotimo ZzZombo: you should be able to just declare my \TheClass := $class and use that as the constraint
no subsets needed at all
moritz babydrop: thanks 15:57
kyclark Writing it as we speak.
timotimo also, "where *.isa($class)" is better written as just "where $class", as long as $class is a proper type object and not accidentally an instance

gregf_ *bookmarks that link*
ZzZombo but if accidentally the type will get passed in as the invocant, then it will pass your constraint, yes?
that construction is a runtime version of $class:D. 15:59
yours is just $class.
kyclark moritz: I guess I’m still trying to frame it. Would take any suggestions. 16:00

plane flight isn't the right opportunity to do it? ;) 16:20
you're free to do whatever you like, of course
oh, thing is: do we want to actually create a list of the exact type given? including the type constraint?
16:20 telex left
timotimo or just "ah they passed in some Positional, maybe the punned role even, we'll just build a list" 16:20
because i could implement it if i knew how you'd like it to behave, exactly 16:21
tadzik I'm flying ryanair, if there'll be enough room to open my backpack... 16:22
timotimo heh heh
tadzik I think a typed list would be more in order
timotimo okay. i wish you a good flight in any case!
typed lists of course have the disadvantage that they won't allow you to append more stuff after creating the initial thing 16:23
kyclark I’m having a bit of trouble pasting in a block of code into the Wordpress site for my Advent entry. Any suggestions?
tadzik flight choice is the unfortunate combo of $gf wanting to fly cheaply but refusing to be gifted a ticket %)
timotimo give up on life. wordpress is the most terrible thing in existence :(
babydrop kyclark: my plan is to write it in markdown, paste it into a github gist, and copy the generated markup and use that in wordpress
tadzik wha, typed lists are immutable? 16:24
timotimo no
tadzik kyclark: last I tried wordpress had a wysiwig editor an an html editor, with the latter working mostly ok
timotimo you can't append *other* stuff ;)
tadzik oh
timotimo some people just like to end all their lists with a Flourish.new()
tadzik I guess that's fair, if that's how you specced your class to unmarshal into :)
timotimo inside classes, you of course have to rely on the .of of the attribute if it's listy to figure out what class to unmarshal into 16:25
tadzik yep
timotimo so i'll come up with some test cases that'll rely on unmarshal($jsondata, Positional[MyClass]) or something 16:26
and maybe even try to implement it

I was wondering if someone could explain that to me (the style, and contrasting preferred style). 18:19
Or, perhaps better yet, point me to an example of what is currently considered good Perl6 style. I plan to start writing some perl6 and I want to form good habits early... 18:20
babydrop thowe: most stuff in github.com/rakudo/rakudo/tree/nom/src/core is good style :D
18:21 pyrimidine joined
babydrop thowe: but I don't think there's anything uber cannonical yet. I prefer to use .foo: method calls and pass int named args as :42bar 18:21
What's "good style" really?
El_Che babydrop: nqp code could be somewhat confusing for someone not doing nqp
babydrop El_Che: read it as a subroutine call... the rest is all Perl 6 18:22
gfldex thowe: examples: github.com/jnthn?tab=repositories 18:23
thowe babydrop, well, "good style" is subjective, like "good health", but like health it is still easy to tell good from bad. Also, communities tend to develop certain standards that, when used, help others absorb your code better. 18:24
El_Che there is good style and (fuzzy) conventions
e.g. there is nothing wrong about $var_name, while perl6 core people tend to use $var-name 18:25
AlexDaniel no space after a comma… meh
babydrop I'd call $var_name a bad Perl6 style tho
thowe I'm still curious about the comment about python bracket style that Brian Foy must be known for and what it is so that I can spot it. Also, what is preferred to it.
El_Che babydrop: why?
18:26 grondilu joined
El_Che there is nothing in the language that discourage it and the code is as readable as with - 18:26
AlexDaniel thowe: this kind of thing: github.com/briandfoy/perl6-chemist...s.pm6#L175
El_Che it's more of a cultural thing
babydrop El_Che: because core stuff uses kebob-case so if you're not using it everywhere, you have incosistent casing in your code and if you publish such an API as a module, you're just propagating the swine casing
El_Che babydrop: if Perl6 gets into that situation it will be a luxury problem :) 18:27
thowe AlexDaniel, Ah. Yeah, I tend to close the bracket at the same column as the opening statement.
babydrop El_Che: which situation?
El_Che babydrop: a zillion of inconsistent apis 18:28
babydrop :S
18:28 pmurias left
babydrop El_Che: I'm not sure where you got that from. 18:28
thowe Although, for C++, I got in the habit of opening the brackets on their own line, also at the same column. Seems to add readablity to C++ and perhaps Java. I think I picked that up from some Qt guys.
babydrop El_Che: we already have DBI that provides half the methods snake_cased and other half kebob-cased
El_Che babydrop: atm I'll settle with incosistent naming between libs for more libs
AlexDaniel sub foo(… … … … …) {
bar;
} # like this? :P
El_Che thowe: I hate that style on java 18:29
thowe: yet again, cultural
thowe AlexDaniel, no

babydrop huh? 19:01
What Message?
AlexDaniel the one that is passed to irc-to-me ? 19:02
babydrop It's IRC::Client::Message
What are you trying to do? 19:03
AlexDaniel babydrop: your champagne thing
19:04 Coffeeframe joined
Coffeeframe Hello 19:04
AlexDaniel hi
babydrop Just `use IRC::Client::Message;` in the help file and put IRC::Client::Message as a type constraint on the multi that prints help
AlexDaniel babydrop: that's my question! How can I type just “Message”?
babydrop That's the only place that you'd need to have it at
AlexDaniel: ummm... constant Message = IRC::Client::Message; I guess
Like here: github.com/zoffixznet/perl6-IRC-Cl...ge.pm6#L16 19:05
AlexDaniel I see… 19:06
babydrop But that's nothing to do with my champagne thing :P
I don't get why you need just Message. You only need it once, on thi sline: github.com/perl6/whateverable/blob...ble.p6#L32 19:07
well, for each robot 19:08

It's just kind of fascinating to read the exchanges; differing view points colliding. 19:21
babydrop Coffeeframe: the `rakudo` package would be compiler only and you'd also need to install a module manager manually with it. The rakudo-star package listed there is ancient.. .even before our first stable release

AlexDaniel why?

AlexDaniel: because otherwise it's useless and unpredictable?
FROGGS are we talking about resolution order of subs and methods? 19:42
err, multis so to say?
babydrop FROGGS: the multi resolution yeah, specifically how it pertains to resolving multis provided by class and its subclasses

It's perfectly predictable, just like with the champagne thing
The Int (or Message) gives more narrowness than the narrowness provided by the thing coming from a subclass 19:45
AlexDaniel yea, that's exactly what I'm saying. Because irc-to-me is always called with Message
babydrop The above code is also called with an Int
also always calledd 19:46

thowe I'm curious about the motivation to post a comment about how you are not going to be using something (Perl6 in this case). It's never occurred to me to comment in a thread about Python or TCL to tell people it has no appeal to me. I have to assume there is some kind of emotion that Perl6 is triggering to make someone say "yeah, well, I'm not gonna use it! Hmf!" 19:47
tadzik I appreciate a Panda reference, as a spirit animal of sorts :)
sounds like someone expressing their insecurity
AlexDaniel babydrop: that's not what I'm saying. I'm saying that it would be better to have an option to set the priority manually, so that it becomes explicit and readable 19:48

babydrop thowe: um, I take it you never used YouTube? :)
thowe I've watched things on YouTube, is that using it?

AlexDaniel [Coke]: the problem is that sometimes in a subclass you want to have a similar signature but want it to have less priority over the one that is in a parent 20:17
[Coke]: additionally, see #123577. It is a slightly different issue, but kinda related
synopsebot6 Link: rt.perl.org/rt3//Public/Bug/Displa...?id=123577
babydrop Well, "problem"
There's a method to do it, but AlexDaniel does not find it palatable :) 20:18
AlexDaniel yea, because you have to change your parent class
babydrop hmmm
20:18 cpage_ joined
babydrop You don't, if the parent class has a type constraint 20:19
babydrop tries another trick if it doesn't...
AlexDaniel what's needed, actually, is “is not important” 20:20
[Coke] if it's not meant to override, and you want it to have the same signature, don't give it the same name.
AlexDaniel but that's kinda not going to work
[Coke] that seems very obvious to me, so I must be missing something.
20:20 grondilu left
[Coke] crap. I'm going to have to give up tmux and go back to screen. 20:21
babydrop [Coke]: the API uses the multi candidates to choose which one to call, so using a different name is not an option
AlexDaniel [Coke]: well, see this as an example: github.com/perl6/whateverable/comm...8a5759f60f
timotimo tadzik: did you also bump the version?

[Coke] (but that's a half baked answer. I'll give it some more thought later.) 20:22
babydrop [Coke]: there is an answer to be described in my Advent article :) 20:23
[Coke] for that kind of thing, I think you want to try all the methods in the hierarchy until someone says "I've processed it", which sounds like something other than method inheritance to me.
babydrop The only niggle is it doesn't work when there's no type constraint on the parent class's method :)
"Ambiguous call to 'stuff'; these signatures all match:"

Actually, that may be a bug 20:24
Because one is a regular method stuff ($) {} and the other is subset MySubset of Mu where { $_ ~~ Str }; method stuff (MySubset)

Technaton Hello, world! Hope I am not intruding. :) I am thinking of creating a Vindinium bot in Perl6. There are some parts to it, e.g., the A* algorithm. Would that algorithm be appreciated as perl6 module, and if so, what would be the best namespace to put it in?
jnthn $key and $value are optional
22:09 espadrine_ joined
jnthn And we call that candidate for Mu 22:10
uh

And it ends up setting them to Mu
Mystery solved.
AlexDaniel jnthn: so why does it say “is default(Nil)” ?
babydrop \o/
jnthn AlexDaniel: Because otherwise assigning Nil to it would lose your Nil
AlexDaniel: is default(Nil) is the only way to get a container that you can assign Nil into 22:11
babydrop Technaton: the module would certainly be appreciated
AlexDaniel jnthn: oh, ok. This part is now clear
Technaton babydrop: Well, I guess that was the stupid part of the question, since m.p6.org doesn't yield any search result for A*. :) 22:12
babydrop Technaton: as for namespace... I see other modules use Algorithm:: so maybe somewhere there?
Technaton: yeah, our ecosystem is baby-sized :D
AlexDaniel ah… so if something should accept Nil as its value, then it will also return Mu if unset?
otherwise I should be expecting Any, right?
Technaton So, Algorithm::Astar? I am trying to get the vibe of p6. Perl5 I know, Ruby I know, I am a long-year C++ programer… P6 is quite unknown terrain.

Technaton Well, I see I have quite a lot to learn. P6 is very different from p5. The interface question is the best way to learn a new language. :)
Thanks for the suggestions!
Is there something akin of template functions in p6? 22:29
For example, in C++, I'd probably define something along the lines of `template <class Node> Node::Iter neighbors(Node const& node);`, and have the user specialize the template to get the neighbors of a tree node (for A*). 22:31
Pro: Clean interface. I could simple have `Path a_star::path(Node const& from, Node const& to)`, even with the five predicates A* needs. 22:32
Pure OO doesn't look so good, it would need an interface and finally multiple inheritance. Quite cumbersome.
How does one create a functional/predicate-based interface in p6? 22:33

timotimo Technaton: you can just take any kind of object and call .neighbours on it, for example 22:36
"duck typing"
you would need templates for the same thing in cpp because you have to compile new code to make it work with different classes; there's no "call method by its name" functionality in vanilla c++ 22:37
22:37 grumble joined
timotimo (qt, for example, adds this) 22:37
22:37 espadrine_ is now known as espadrine
Technaton Okay, in the same way as, e.g., a Ruby programmer would do it. So I've got "node.neighors", "node.heuristic(to)", etc. - But the point is: How do I convey that clearly to the potential API user? In C++, a bit of doco and the compiler suffices (cf. boost), but with duck typing, how does one figure out how to implement this kind of "deep interface" correctly? It's not simply an abstract interface (i.e., 22:38
API) to program against…
Perhaps I'm just an old guy, but I'm willing to learn new tools. 22:39
timotimo write it into the docs? maybe supply a role that user code can inherit that makes sure the necessary methods are all implemented?
Technaton How do I make sure that all necessary methods are implemented? By supplying a default method that throws an exception? 22:40
I'm just asking widely, coming from another language I've used for 10 years. Sorry if the questions seem overly naive. 22:41
*wildly
kyclark Technaton: docs.perl6.org/language/operators#...b_operator 22:45
Would that work? Kind of like declaring abstract methods?
Technaton kyclark: "Abstract methods": I don't want them. I would ideally like the user to supply some predicates, the way Boost.Graph does it, for example. I know that this probably sounds obsucre, since its not the usual "here, implement that interface" stuff. 22:46

geekosaur iirc .push follows the single-arg rule, so if you (*.push: @a) it pushes a single item containing the list instead of all the elements separately 22:57
TimToady that's not the single-arg rule, that's just a single arg :) 22:58
single-arg rule expands a single arg into multiple
