»ö« Welcome to Perl 6! | perl6.org/ | evalbot usage: 'perl6: say 3;' or rakudo:, niecza:, std:, or /msg p6eval perl6: ... | irclog: irc.perl6.org/ | UTF-8 is our friend! | Rakudo Star Released! Set by diakopter on 6 September 2010. |
|||
| Tene | takadonet1: you tried to use a placeholder in a sub with a signature. | 00:03 | |
| rakudo: sub foo($n) { say $^a }; foo(5); | |||
| p6eval | rakudo a95c1d: OUTPUT«===SORRY!===Placeholder variable cannot override existing signature at line 22, near "; foo(5);"» | ||
| Tene | see? | ||
| takadonet1 | ... some wha | ||
| what* | |||
| Tene | takadonet1: placeholders are an *alternative* to using a signature. | 00:04 | |
| takadonet1 | well i need a signature in this case | 00:06 | |
| well i think so | |||
| Tene | Then put the placeholder you're trying to use in the signature instead. | ||
| Perhaps we could see the code? | |||
|

|||
| takadonet1 | Currently it's over two module and about to leave ..... | 00:07 | |
| trying to golf it down as we speak | |||
| Tene | takadonet1: quick explanation of placeholders: the following two functions are equivalent: sub foo($a, $b) { say $a + $b }; sub bar { say $^a + $^b }; | 00:08 | |
| also: sub foo(:$a, :$b) { $a+$b }; sub bar { $:a + $:b } | |||
| takadonet1 | ic | 00:09 | |
| Tene | so instead of listing a formal signature, you annotate at least the first usage of that variable with a twigil, and all so-marked placeholder variables are aggregated, sorted alphabetically, and used to construct an implicit signature. | ||
| This is incompatible with an explicitly-listed signature, as the combination would be non-obvious. | 00:10 | ||
| So you're using $^foo or $:foo somewhere in your code, where you don't actually mean to be. | |||
| So, search for those twigils | |||
| takadonet1 | Tene: thanks for the help | 00:11 | |
| sucks that I gtg :( | |||
| Tene | takadonet1: np glad to help | ||

| phenny | uasi: I'll pass that on when masak is around. | ||
| TimToady | seems the fundamental problem is actually in .bless | 05:05 | |
| anyway, this is probably parrot's p5ish semantics showing through | 05:06 | ||

| jeeger | moritz_: I converted it to epub with calibre ebook-convert, and it looks pretty nice on my reader. | ||
| moritz_ | jeeger: I tried it via the calibre GUI (from the html file), and it mangled the code sections | 13:46 | |
| ie removed whitespaces | |||

| moritz_ | jeeger: scroll down :-) | ||
| jeeger | moritz_: Yep, mangled. | ||
| hmmm | |||
| moritz_: Hm, the html target doesn't output html. That could be the problem. | 13:49 | ||
| ah, forget it. Less filtered the tags | |||
| moritz_ | it's HTML, but without header (iirc) | ||

19:21

|||
| lue | Why would you want to use actions? I see "accessing the results in an easier fashion" as the answer, but I'm not sure. | 19:27 | |
| moritz_ | that's exactly it | 19:28 | |
| tadzik | also, it scales well | ||
|
19:28
hercynium joined
|
|||
| tadzik | as the last year advent calendar entry says :) | 19:28 | |
| masak | usually, what you want to do when you get the tree of matches from the grammar parse, is to traverse that tree. actions are an easy way to do that *while parsing*, with much of the traversal boilerplate hidden. | 19:29 | |
| tadzik | actions are one of the most terrifying things before, and the most amazing once you learn them | ||
| s/once/after/ | |||
| masak | actions are the natural next stepping stone after one learns grammars. | 19:30 | |
| arnsholt | Actions are bloody brilliant | 19:31 | |
| =) | |||
| lue | [looking at book] Seems like actions are natural for such things as Pod parsers. I think I will most likely use them, after reading up on them. | ||
| colomon | actions++ | 19:33 | |
| masak | lue: sounds excellent. ask as soon as you have more questions -- so far they've been great. | ||
| arnsholt | lue: Actions are a natural thing for parsers =) | ||
| lue | It would explain why I thought &parse was a bloody difficult thing to use. colomon++ for his advent post (day 18), for without it I would have only known of actions as a file in rakudo :) | 19:34 | |
| colomon | Glad it was useful to you. :) | 19:35 | |
| for sure grammars + actions are fantastic. | |||
| masak | I think pmichaud mentioned that he invented actions (in Perl 6). | 19:36 | |
| colomon | really? I just assumed it was part of the original grammar scheme. | ||
| masak | no, I think not. | ||
| one nice thing is that one can have several action classes for the same grammar. | |||
| depending on the desired backend, for example. | 19:37 | ||
| colomon | I've been wondering how well that will work in practice. | ||
| masak | time will tell. | ||
| colomon | I've noticed that I've tweaked the ABC grammar to make it work better with the actions I am currently writing. | ||
| masak | that sounds like a very sane thing to do. | 19:38 | |
| colomon | not clear that the tweaks would work properly for a completely different set of actions. | ||
| masak | well, the actions are a sort of "client" to the grammar. | ||
| colomon | I think it will be very interesting to see where best practices for them lands four or five years from now. | ||
| masak | so making the grammar conform to what the action(s) desire is only natural. | ||
| of course, with many action classes, there might be competing constraints. | |||
| but there likely would have been anyway, due to waterbedding :P | 19:39 | ||
| lue | rakudo: Grammar G { regex TOP { ^ <alpha>+ $ } }; class G::Actions { method TOP($/) { make "You said $/" } }; G.parse("hello", :actions(G::Actions.new)); say $/.ast; | 19:43 | |

| p6eval | rakudo 96d7e0: OUTPUT«You said hello» | ||

| masak | lue: very good. now answer me this: are actions top-down or bottom-up? | ||
| lue | .oO(hm. I would guess, but that's not the point.) based on what I've seen so far, I would guess top-down. |
19:45 | |
| flussence | is there a way in rakudo to write a MAIN(Str ~~ any(@command-names)) so that the auto-generated help text lists the @command-names? | ||
| tadzik | I'd go for writing my own USAGE | 19:46 | |
| masak | lue: they're bottom-up. | ||
| lue: smaller rules finish before the bigger rules do. TOP finishes last. | |||
| flussence | oh wow, there's a USAGE sub? learning something new every day :) | 19:47 | |
| tadzik | :) | ||
| the “help text” is the default USAGE sub | |||
| lue | I can tell there are some implications to that, but I don't see it. [TOP stomps on smaller rules' asts?] | 19:48 | |
| tadzik | lue: the smaller tokens are "make"'d first | 19:49 | |
| time for me, see you zebras! | |||
| masak | tadzik: \o :) | ||
| tadzik | (and I plan to come back with one or 2 Rakudo patches, but shh!) | 19:50 | |

| thundergnat | Good * #perl6 | 20:41 | |
| colomon | \o | 20:44 | |
| thundergnat | When you have a sort modifier block, is it legal to have a secondary sort term in the modifier block? I vaguely remember seeing code like that somewhere but can't seem to find it anywhere. | 20:50 | |
| Or does that even make sense? | |||
| colomon | I'm not sure. | ||
| thundergnat | for instance, sort by word length with a secondary ASCII sort: my @sorted = @unsorted.sort: { $^a.chars, $^a }; | ||
| colomon | ah! | 20:51 | |
| I think that's legal in theory but NYI in Rakudo. | |||
| thundergnat | I sort of works locally | ||
| but it is buggy if it is legal | |||
| colomon | sure, if you encode both things to a single thing that cmp works on it will probably work already. | 20:52 | |
| flussence | rakudo: <duck cake umbrella cardboard>.sort({ $^a.chars, $^a }).Str.say # now I'm curious | ||
| p6eval | rakudo 96d7e0: OUTPUT«cake duck umbrella cardboard» | ||
| colomon | I'm trying to remember what the name is of the official type. Ordering, or something like that... | ||
| flussence | rakudo: <duck cake umbrella cardboard>.sort(*.chars, *).Str.say # will this work? | 20:53 | |
| p6eval | rakudo 96d7e0: OUTPUT«Too many positional parameters passed; got 3 but expected between 1 and 2 in 'Parcel::sort' at line 1395:CORE.setting in main program body at line 22:/tmp/eCzVnSjbDI» | ||
| flussence | it'd be nice if that did... | ||
| colomon | Ordering, indeed. | ||
| thundergnat | it ""works" except it does a string comparison on the word lengths. | ||
| so length 10 sorts before length 2 | 20:54 | ||
| colomon | still don't know where it's defined in the spec, alas. | ||
| thundergnat | colomon: yeah, I couldn't find it either... | ||
| colomon | it's definitely NYI in Rakudo. | ||
| you can do this the other way, though... | |||
| thundergnat | Sigh. That would (will) be so cool... | 20:55 | |
| colomon | rakudo: <duck cake umbrella cardboard>.sort({ $^a.chars <=> $^b.chars || $a leg $b }).Str.say | ||
| p6eval | rakudo 96d7e0: OUTPUT«cake duck umbrella cardboard» | ||
| thundergnat | Since sort is stable, could easily do my @sorted = @unsorted.sort.sort: { $^a.chars }; | 20:56 | |
| colomon | Hmmm... you may well be right about that, but I don't see stable in the spec, and I'm not sure I'd trust Rakudo actually have stable sorts yet. And writing out the comparison the long way does work now. | 20:59 | |
| rakudo: <duck cake umbrella cardboard>.sort.sort(*.chars).Str.say | 21:00 | ||
| p6eval | rakudo 96d7e0: OUTPUT«cake duck umbrella cardboard» | ||
| colomon | well, that works. thundergnat++ | ||
| flussence | grr... trying to write a MAIN sub so I can do "perl6 ./program commandname", but it's not working: | 21:03 | |
| multi sub MAIN(Str $command where { $_ ~~ @commands }) { } | |||
| moritz_ | flussence: did you mean: $_ ~~ any @commands ? | 21:04 | |
| flussence | probably :) | ||
| colomon | moritz_++ | ||
| flussence | that's the one... I'd been trying a bunch of different things and that was what I gave up at | 21:05 | |
| thundergnat | colomon: according to the perl6 book github.com/perl6/book/blob/master/...asics.pod, perl6 has stable sort, and I am willing to take that as authoritative. | ||
| moritz_ is wililng to take the spec as authoritative | 21:07 | ||
