I think these days it is way too much to expect people to read and
remember(!) the documentation.
At least no up-front.

However a more common case is the frequent language switching. I keep
typing Python constructs in Perl and Perl constructs in Python. Not to
mention Perl 5 vs 6 constructs. And JavaScript too.

I have not given much thought to it, but I'd like my language to treat
me as a human. Instead of telling me I am stupid, it should give me
direction to fix the problem. Pointing at the specific paragraph in
the documentation can be part of it.

Rakudo does this quite well in some cases. In others less so.
The thing is that now that I try to recall when did Rakudo do well I
cannot really remember.
And that IMHO is a good thing.

Re: [perl #131583] [BUG] Sort content of ^methods

[Gabor Szabo]

I think the question when would ^methods be used?

Would it be used by people who use the REPL to experiment with the
languages? In that case the listing should be as user friendly as
possible and require as little typing as possible. Having ABC order is
IMHO the easiest to look through.

(e.g. in python it is dir(object) )

If there was some other, even easier way to get this list, that would
be even better.

Re: [perl #123578] shouldn't site be earlier in @*INC ?

[Gabor Szabo]

If I recall correctly in Perl 5 the resolution was that the directories in
@INC are ordered
site, vendor, system

I am not sure about Perl 6, but with the above layout I think system would
hold the modules of Rakudo.
vendor would hold the modules of Rakudo Star and site would hold the stuff
that I install myself
using Panda or otherwise.


I ran some experiments from scratch in two ways: (with and without giving
--prefix)
using Rakudo Star 2014.12.1  Source code version and built it on OSX.
I hope these help and I have not just spent time on something that was
already obvious
to everyone else.

 That's quite dangerous. Precompiled modules (on which scripts often
 depend) only work with the rakudo that compiled them. If a different one
 is in $PATH before that, the scripts will start to fail with weird errors.


Well, I am not suggesting it should be set that way, I don't know how it
'should' be.
I was just reporting what worked and what did not work for me.




 Does #!/usr/bin/env /full/path/to/perl6-m work?


yes, I just tried putting this in p6doc:

#!/usr/bin/env /Users/gabor/rakudo-star-2014.12.1/install/bin/perl6-m

Re: No more Rakudo *?

[Gabor Szabo]

I started to write a stand-alone script that would build and test
Rakudo and then a bunch of modules,
but probably it would be easier to just try to build Rakudo *
including all the modules and
put together a report on issues encountered.

I cloned Rakodo * from https://github.com/rakudo/star and tried to build it with

perl Configure.pl --gen-parrot

it complained I am in a .git directory and then quit.

I tried to force it using

  perl Configure.pl --gen-parrot --force

this time it stopped with

   Unable to read rakudo/tools/build/NQP_REVISION

The README of Rakudo * tells me there is supposed to be a rakudo/
subdirectory, but there
isn't and the subdirectories inside modules/ are also empty.

Do I first need to manually clone Rakudo and the modules from Gihub
and then use the --force or is
there something else I need to do?
Do I understand correctly that in a real Rakudo * release you'd check out the
labeled release of Rakudo and the latest versions of the modules and
then start the build process?

regards
Gabor

No more Rakudo *?

[Gabor Szabo]

http://rakudo.org/ tells me the latest Rakudo * was more than 2 months ago.
(version 2013.02)

Besides, it would be nice to see plain Rakudo release announcements
reach that site.
Even if only a few lines.

regards
Gabor

Rakudo * 2013.02

[Gabor Szabo]

1) I think it has not told me the installation finished - it was just done.
2) It installed in c:\rakudo without a question or without telling me
it will do so
3) It has not configured PATH to include c:\rakudo
After doing it manually, perl6 -v worked from the command line.

4) You cannot use p6doc from the command line so I created a file called
c:\rakudo\bin\p6doc.bat   with the following content:
@%~dp0perl6.exe %~dp0p6doc %*

this will launch the perl6.exe from the same directory where the
p6doc.bat file is and will pass all the
parameters it got to the script.  After that runningp6doc Str  worked

5) Same with panda
c:\rakudo\bin\panda.bat   with the following content:
@%~dp0perl6.exe %~dp0panda %*

Explanation:
The leading @ turns off echoing the command
%~dp0 is the path to the directory where the bat file currently
executed can be found, it already includes the trailing back-slash \
%* includes all the command line parameters

6) After a bit of searching I found that the
c:\rakudo\lib\parrot\4.10.0\languages\perl6\lib is the location where
the modules coming with Rakudo * are installed
but I have not found any easy way to list them. Is there any? Is there
a list of the modules that come with Rakudo * ?

That's it for now.

This is an 64 bit Ubuntu 12.4 VPS (hosted on Linode) with 512 Mb
memory and 1 Gb swap space.

After running it again, I got the same error but I did not see the
memory filling up,
so maybe it is not a memory issue.

How to get Rakudo for Windows

hi,

probably it would be nice if on http://rakudo.org/how-to-get-rakudo/

where can people get the msi windows installer from?

adding line numbers to Test.pm failures

[Gabor Szabo]

Hi,

when something fails Test::More of Perl 5 can tell me which line in
the test file it was called.

I see the Backtrace module could supply this information.
The question if it would be ok if I tried to add this to the Test.pm module?

Re: a method with the name of an attribute creates infinite loop

[Gabor Szabo]

Oh, once I found the problem, I just renamed my method. That's ok.
The thing is that it would be nice if Rakudo caught this and told me about it
as I think I am not the last one to make this error.

Anyway, thanks for your solution too!

regards
   Gabor

 If I recall correctly, calling @.add() is the same as @(self.add). Calling a
 method recursively without ending is bound to go into an infinite loop :)

 To avoid that you can call push on the attribute, directly, without going
 through the accessor method:

 === CODE ===
 class A {
has @.add;
method add {
   say 'before';
   @!add.push( 42 );
   say 'ever after';
}
 }

 A.new.add;

 Which works without problems:
 === RESULT ===
 before
 ever after


 Kind regards,

accepting incorrect syntax?

[Gabor Szabo]

I wonder if the first one is a bug:


use v6;
my @x = (
{ a = 1}
{b = 2 }
);
say @x.perl;

prints  Array.new({b = 2})



Almost the same code:

use v6;

say @x.perl;

 This is actually correct. It parses as


 my @x = ( {a = 1}; {b = 2} );

 Which is roughly the same as

 my @x = ( do {  {a = 1}; {b = 2} });

 In general, a semicolon can be omitted after a closing bracket before the
 end of the line. That's why you don't need a semicolon after

 if $condition {
say 'something';

 }


 Almost the same code:

 use v6;
 my @x = (

 );

 Niezca has a better error message:

 Unexpected block in infix position (two terms in a row, or previous
 statement missing semicolon?)

Thanks for the explanation.

This means the newline matters.

Rakudo compilation failure

[Gabor Szabo]

I have a freshly cloned rakudo and tried to build it on an Ubuntu
12.04 (32 bit) it failed here.
The machine has 512Mb RAM and 256 Mb swaps space and it seems they
were both full.

Is that it or they are unrelated? How much is the minimum memory required?

 Gabor -


 Sorry for the delay in responding. This ticket is over a year old - can you 
 still reproduce this
 problem?

Yes, this still gives me segmentation fault but now the test suit of
Parrot::Embed also fails with

ga...@localhost:~/work/rakudo/parrot/ext/Parrot-Embed$ perl Build test
t/00-load.t  ok

Parrot on Android

[Gabor Szabo]

Android already supports various languages. I think it would be cool
to see Parrot being supported there which will allow running
Perl 6 code on Android.

I took the liberty and submitted a request.

Please visit the request page and click on the star to upvote it!
You might also add a comment but it is not necessary.

Re: Oslo Perl 6 Hackathon Notes

Hi,

 As some of you are aware, this week is the Nordic Perl Workshop [1],
 and in the days immediately following the workshop we will have
 the Oslo Perl 6 Hackathon [2].  During the first day of the hackathon
 Gabor Szabo will be doing a Hands-on Perl 6 training course [3],
 the other two days will be for various hacking tasks (both Perl 6
 and Perl 5).

just to make it clear, on the first day 1 room will be allocated to the
Hands-on and the other 2-3-4 rooms will already be allocated to the
Hackathon.

 I personally have three goals for my participation at the
 workshop and hackathon:

 *  Attend Gabor's course and take careful note of where issues
 arise with using Rakudo Perl and/or Perl 6 (including filing
 bug reports and/or answering questions as needed).

That will be great. At least someone in that hands-on will know the stuff.

Re: [perl #63970] split() returns the delimiter, not the substrings

 perl6 -e'say a;b.split(;).perl'
 [a, b]

 but

 perl6 -e'say split(a;b, ;)'
 ;

 In the sub form the delimiter still goes first (like in Perl 5), so it
 tries to split ';' by 'a;b', fails, and thus returns the whole string is
 one chunk. Works as designed.

and I even reported it as a bug

how embarrassing

I blame the hour.

   They are a non-profit organization.  Yeah, kind of suprising that would be
   the frustrating thing.  The issue is that they can't take money from Bob to
   give to Sue to work on Bob's widget.  This is an extreme oversimplification
   but in general, they have to abide by the rules that allow them to keep
   their non-profit status.  Where am I going with this?

  This doesn't make any sense to me. There's nothing about being a nonprofit
  that prevents TPF from accepting donations targeted to a specific program.
  There's a bit of accounting overhead to make it happen, but it's perfectly
  legal and in keeping with TPF's 501c3 status and its mission.

I don't know but I think I was told at least once that TPF cannot
handle donations
targeted to a specific person. That might of course be different then targeting
at specific program, I am not familiar what 501c3 means.

Personally - and there might be few others - I'd be much more
comfortable to give
money to a specific target or person than to a general pool.

What I was hoping for a long time is to be able to give a modest amount
on a monthly basis. Currently AFAIK TPF can only accept stand alone payments.

IMHO many people in the community would be ready to give 5-10-20 USD/month but
it would be much harder to get them give 100 or 200 USD once a year.

How hard would it be to enable (Paypal?) recurring monthly payments to TPF?
How hard would it be to allow people to target their money to a
specific project/person?


TPF can then still focus on raising money from corporations.

Re: Official Perl 6 and Parrot wikis

 .cgi?  Is that really a CGI-based implementation?  Because that seems
 a little, I don't know, backward-looking.  Maybe it's just me, but it
 seems like it will just feed the all-too-common perception that Perl

 something else (be it Java, PHP, Ruby/Rails, whatever).

 Besides, I hope that the language and wiki will be successful enough
 that a cgi-based implementation will completely fail to scale to meet
 demand. :)


Maybe the site maintainers could add an Apache rewrite rule
so the URLs used by the public will be

   http://www.perlfoundation.org/perl6/index.p6
and
   http://www.perlfoundation.org/parrot/index.parrot

That would change the perception and we would not need to explain
about mod_perl running the .cgi scripts at the rate 100-200 faster
than good old CGI.

When asked if they really run on Perl 6 and Parrot we could just smile...

Hi all,

I'd like to get opinions from developers on this list. I'm looking
into this system that executes massive amounts of Perl 5 code on a
Perl 5.8 interpreter.  The system burns tons of CPU while running Perl

billion inst per module - 10 billion inst/modl) and latency (say, 2
sec/modl - 0.5 secs/modl).


Have you tried to profile your code and see if there are place to do
optimizations?
