Limbic_Region |
is there going to be a nice safe way to refer to a very::long::module::name with a short and descriptive lexical alias or similar? |
| 15:20 |
cognominal_ |
::= or something similar allows to make an alias |
| 15:21 |
particle_ |
:= is runtime, ::= is compiletime, iirc |
| 15:21 |
Limbic_Region |
and that works with namespaces in general or just to things inside that namespace |
| 15:21 |
Limbic_Region |
? |
| 15:23 |
particle_ |
well, :: is a sigil |
| 15:23 |
particle_ |
so i *imagine* '::foo := very::long::module::name' might work |
| 15:24 |

szbalint |
fellow hungarian. :) |
| 15:33 |
b_jonas |
hello |
| 15:34 |
b_jonas |
right, I'll ask a question I've just asked on perlmonks |
| 15:34 |
szbalint |
oh you're that ambrus. Cool. :) |
| 15:34 |
b_jonas |
I'd like to know if there'll be a standard way of using a module and giving it a lexical alias name |
| 15:35 |
b_jonas |
so that you can refer to it with a shorter handle |
| 15:35 |
Limbic_Region |
from about 13 minutes ago |
| 15:35 |
Limbic_Region |
[11:23] <particle_> so i *imagine* '::foo := very::long::module::name' might work |
| 15:38 |
b_jonas |
I'd like if that became a standard thing to do (that is, supported by the docs and community and possibly a simple syntax) |
| 15:38 |
b_jonas |
so that we can have descriptive module names but use such modules easily |
| 15:40 |
particle_ |
i'm sure it'll be idiomatic perl 6 |
| 15:40 |
Limbic_Region |
which S covers namespaces anyway? |
| 15:40 |
b_jonas |
S10 to S12 |
| 15:41 |
particle_ |
yep |
| 15:41 |
particle_ |
S02 covers sigils, that's where i started looking |
| 15:41 |
particle_ |
however, it's unclear from S02 what the syntax would be |
| 15:41 |
b_jonas |
I looked at S11 first but didn't see anything like 'Foo := use Bar::Foo;' or 'use Bar::Foo as Foo;' |
| 15:43 |
b_jonas |
this of course wouldn't be a problem in a language which only has one kind of variable AND that includes packages too, |
| 15:43 |
b_jonas |
but the only such language I know is lua |
| 15:43 |
|
bjoern_ is now known as DEpwnsCR |
| 15:43 |
b_jonas |
and there you can indeed assign packages. |
| 15:43 |
b_jonas |
only, packages are mostly just tables |
| 15:44 |
particle_ |
you might enjoy playing with lua on parrot |
| 15:48 |
b_jonas |
in c++, you can alias a namespace by creating a new one and importing the first namespace in it; and alias a class by typedef or inheriting; |
| 15:48 |
b_jonas |
but in perl these operations aren't transparent |
| 15:50 |
* b_jonas |
looks at cltl to see how common lisp packages work |
| 15:51 |
b_jonas |
anyway, there's a strange way I imagine this could be done: |
| 15:52 |
b_jonas |
in this, the module file would contain like 'module { ... }' or 'class { ... }' |
| 15:52 |
b_jonas |
the use statement would return an anon/package which you had to assign to a (lexical) name |
| 15:52 |
b_jonas |
like 'Foo := use Foo' |
| 15:53 |
b_jonas |
or better 'Foo ::= use Foo' |
| 15:53 |
b_jonas |
and for convenience a use in void context would be equivalent to this with a sensible default name |
| 15:54 |
b_jonas |
naturally, it would still run the file once only, and would just return the same module if use is called again |
| 15:54 |
b_jonas |
this idea however disregards imports |
| 16:01 |
particle_ |
well, i hope the syntax exists (and i think it does) |
| 16:01 |
particle_ |
but i can't find the magic incantation |
| 16:01 |
b_jonas |
I hope too |
| 16:03 |
particle_ |
i can't find tests for it in the pugs repo, either |
| 16:04 |

Limbic_Region |
if b_jonas doesn't have a comitt bit I could certainly hand one out |
| 16:07 |
Limbic_Region |
that way there would be no excuse for not sending a msg to the list confirming speculation and submitting a test case too |
| 16:08 |
b_jonas |
uh |
| 16:08 |
Limbic_Region |
so what's your email again? |
| 16:09 |
szbalint |
oh yeah |
| 16:09 |
szbalint |
:) |
| 16:10 |
b_jonas |
I don't need a commit bit just to write a test |
| 16:10 |
b_jonas |
but anyway, my email is (msg) |
| 16:13 |
Limbic_Region |
there - commit bit sent |
| 16:13 |
b_jonas |
oh no, but I didn't want... |
| 16:14 |
Limbic_Region |
too late |
| 16:14 |
Limbic_Region |
we all expect a test case to be comitted now |
| 16:15 |
* particle_ |
expects the AUTHORS file to be modified soon |
| 16:16 |
b_jonas |
I don't even have perl6 installed or anything. I don't know what exact syntax I should use and all that. |
| 16:16 |
szbalint |
The commit bit is free here and its handed out liberally. :) |

b_jonas - there are plenty of examples http://svn.perl.org/perl6/pugs/trunk/examples/ |
| 16:18 |
b_jonas |
I mean what syntax for assigning a module |
| 16:18 |
Limbic_Region |
there are also plenty of tests http://svn.perl.org/perl6/pugs/trunk/t/ |
| 16:18 |
Limbic_Region |
b_jonas - perhaps you missed the part where I said send a message to the list confirming speculation (and then commit a test) |
| 16:19 |
Limbic_Region |
make something up that seems reasonable - send it to the list - let @larry chew on it and spit something back out - commit the masticated cud |
| 16:21 |
particle_ |
you make it sound so romantic :) |

fglock - it would be way OT for me to describe what I am really doing here |

* Limbic_Region |
found Parse::Yapp to be amazingly better than Parse::RecDescent despite not having nearly the documentation and having to write your own lexer |
| 16:26 |
fglock |
I'm working on misc/pX/Common/Pugs-Compiler-Precedence - it wraps Parse::Yapp into something more usable by the p6 compiler |
| 16:26 |
fglock |
I'm planning to integrate it into the PCR distro - it will return a Match object |
| 16:27 |
fglock |
and accept rules as the lexer |
| 16:27 |
|
xern joined perl6 |

Limbic_Region |
ok - so this will all be useable for us mortals still in p5 land? |
| 16:27 |
fglock |
sure |
| 16:28 |
Limbic_Region |
well - any ETA on usability? |
| 16:28 |
Limbic_Region |
I have finished rolling my own, a half dozen P::RD implementations, a Parse::Yapp implementation, and moving on to HOP::Parser next and have about 4 others beyond that to try |
| 16:29 |
Limbic_Region |
I am going on vacation for the next week and a half so there will likely be about a month or more before I am ready to publish a series of meditations |
| 16:29 |
fglock |
it is already in use by Pugs-Grammar-Perl6 - but PGP6 is currently broken, possibly because of the token/regex/rule implementation in PCR - I plan to fix it later on |
| 16:29 |
Limbic_Region |
I would absolutely love to be able to include a "and here is what p6 has to say on the matter that you can use today in p5" |
| 16:30 |
Limbic_Region |
ok - will touch base with you when I am closer to finishing up with the other parsers I know about to date |
| 16:31 |
fglock |
I plan to change PC-Precedence API to make it interact with rules more easily |
| 16:32 |
|
lisppaste3 joined perl6 |
| 16:33 |
fglock |
you can try Pugs::Compiler::Token if you don't need backtracking - it's the fastest parser I could implement so far |
| 16:35 |
fglock |
there is a benchmark in misc/pX/Common/Pugs-Compiler-Rule/benchmark.pl - it would be nice to have P::RD in that benchmark |
| 16:35 |
Limbic_Region |
fglock - I don't <i>need</i> anything - this is an experiment in breaking the rules |
| 16:36 |
fglock |
breaking the rules, tokens, and regexes |
| 16:36 |
Limbic_Region |
more specifically - in what lessons one learns (both good and bad) by breaking the rules |
| 16:37 |
fglock |
oh, that's what misc/pX/ is about |
| 16:38 |
Limbic_Region |
well, so far I have learned quite a bit |
| 16:38 |
Limbic_Region |
I was expecting most of the lessons to reinforce the rule(s) but so far, that hasn't been the case |
| 16:39 |
fglock |
I look forward for reading your meditations |
| 16:39 |
Limbic_Region |
oh, btw, it's getting contagious - see http://perlmonks.org/index.pl?node_id=554516 # bart posted his own operator precedence parser |
