Re: explicit line termination with ;: why?
I don't want to argue about the design of perl6[1], I just wonder: why
the semicolon is still needed in the end of lines in perl6?
JavaScript allows to omit semicolumn. In lecture at Yahoo's YUI
Theatre one of JS's gurus talked about how it is organized in
JavaScript parser.
If the line of code is not ended with ';' the parser tries first
to assume that the next line continues current one. If then syntax error
occurs, the parser _goes_back_ and make another asumption that previous
line was ended with semicolumn.
Probably there are much more than one way to implement ';'-less but it
either slows down the compiler or makes grammar more complex.
And in fact Perl 6 already allows not to type ';' at the end of
{block} ;-)
The following simple snippets work correctly with Pugs and perl5:
perl 6
sub debug ($value)
{
say $value
}
debug 'me'
# perl 5
sub debug
{
print shift
}
debug 'me'
And finally, Perl is not an Assembler with one only instrucion per
line.

Re[2]: explicit line termination with ;: why?
Aankhen wrote: Speaking of JavaScript, any experienced JavaScript programmer will tell you that while semi-colons are in fact optional, you should always treat them as mandatory, to avoid subtle errors creeping into your code. We should also note that the idea of omitting ';' is not as simple as \n always means ;\n. In mentioned JavaScript language one can do this: script var x = 123 alert ( x ) /script and that will work! ;\n can almost always be converted into \n but not vice versa. -- Andrew Shitov __ [EMAIL PROTECTED] | http://www.shitov.ru
Is Perl 6 too late?
=HI! To avoid any uncertainty: the subject is a parody for similar discussion on perl6-internals@ about Parrot. =FOREWORD What I want to say is that after N years of developing Perl 6 we do not have a practical (P in Perl stands for Practical) tool which can work in real life. Even worse: today there is no way to speed up the interpreter - it is good for parsing the language but is very slow for real applications. (mod_pugs is not the case while there is no command-line tool). =EXPLANATION We have Pugs to play with. We have no tool to run with. Current Pugs have options to compile the programme into several intermediate languages, for example PIR: You can pugs -CPIR helloworld.pl helloworld.pir But you cannot later do this: pugs -BPIR helloworld.pir Standalone parrot does not help. =WHAT IS TO BE DONE What is nedded is a very simple step: complete the Pugs compiler so that it could provide good PASM (PIR). Going this way we will achieve the main goal: it will be possible to use hi-speed applications written in Perl 6 today. No care the language itself is not fully standardized. It will change the status of 'conception' and 'project' to 'utilizing' and 'using'. =CUT A bit of fun is that three years ago the situation was better: language was more poor, the tools for more pure. In April of 2004 I made a toy server with demos of how real Perl 6 works on a web-server. There was a bit of examples with comments in Russian that were written on real Perl 6 of that day, compiled into Parrot bytecode (.pbc) and run on Apache under Parrot virtual machine. I cannot do the same with today's instrumentary (or maybe I do not know how to?). Thank you for understanding :-) -- Andrew Shitov __ [EMAIL PROTECTED] | http://www.shitov.ru
Executing Perl 6 code using PIR backend
Hi perlers, maybe I have missed something but I cannot run pugs with -C option. Initial goal was to compile Perl 6 programme into bytecode and run it (with parrot or even mod_parrot). First step is to convert the simpliest code test.p6 which contains say 'Hi!'; into .pir-file, so I typed pugs -CPIR test.p6 test.pir and really received test.pir file. What to do next? There are two ways in mind: either use pugs -B or parrot. When I call pugs with an option -B pugs -BPIR test.pir an error occured: *** Unexpected ' expecting comment, operator, statement modifier, ; or end of input at h.pir line 2, column 6 Looks like -BPIR is totally ignored. The same error you will get if simply run pugs test.pir. OK, trying to use parrot for executing PIR-code: parrot test.pir Plenty of errors this time: error:imcc:syntax error, unexpected DOT in file 'h.pir' line 7 error:imcc:syntax error, unexpected DOT in file 'h.pir' line 180 error:imcc:syntax error, unexpected DOT in file 'h.pir' line 194 . . . All these 'unexpected DOT' messages correspond to staments in PIR-source with 'new' instruction such as $P8 = new .PerlArray Would anyone tell me how to deal and live with it? :-) Pugs -v is 6.2.13 and parrot -V is 0.4.10 --without-icu on i386-linux. -- Andrew Shitov __ [EMAIL PROTECTED] | http://www.shitov.ru

Whitespace (Was: [RELEASE] Pugs 6.2.9 released!)
I am glad to announce Pugs 6.2.9, released during Ingy's OSCON talk:
http://pugscode.org/dist/Perl6-Pugs-6.2.9.tar.gz
SIZE = 1439642
SHA1 = efd32419dcddba596044a42564936888a28b3c69
Following last month's plan, this release features a Perl6/PIL to javascript
code generator, written in Perl 5, currently passing 64% of the test suite.
We also see the beginning of a code generator from PIL to perl5, and a
self-representing Perl 6 object model prototype. The new PIL design and
runcore is also progressing nicely, which should give a more robust
specification to Perl 6's compile time and runtime semantics.
A live CD is available as usual, courtesy of Ingo Blechschmidt:
http://linide.sf.net/pugs-livecd-6.2.9.iso
Ingy's slides are under the Pugs tree as
docs/talks/oscon-apocalypse.spork and
online at http://www.kwiki.org/apocalypse/start.html in HTML.
All in all, it's a lot of fun. Check out the two movies we made for the
OSCON talk as well:
http://no.perlcabal.org/~autrijus/oscon05-autrijus.mp4
http://no.perlcabal.org/~autrijus/oscon05-stevan.mp4
Change the .mp4 to .swf or .wmv for alternate video formats.
Very simple question:
why do we have to give up a space when calling functions under Pugs?
A need to type open('file.txt') instead of open ('file.txt') makes
me perplexing (not perl-flexing ;-) Our recent discussions in 'zip with()'
gave no answer.

Re: Whitespace
print (1+2)*3; can print 9, instead of 3. I'd prefer always have '3' (as a result of sum 1 + 2) here. A C-programmer would tread this like (print (1 + 2) * 3); # prints int, then returns void print (or do)? And is print .(1+2)*3 allowed? in fact, that is exactly (print.getArgument(3) * 3); the same as above. so why not 'print($x)' == 'print ($x)' ;-) -- Andrew.
Re: $pair[0]?

say $pair{'name'}; # prints 'age'
say $pair['name']; # why prints 'name'? == question

Re: unicodian monospace fonts for windows(?)
AT oh my.. it seems to me, that Perl6 starts new age of ASCII-graphics. (not AT ASCII, really.. maybe Uni-graphics?).. I hardly think Perl 6 should avoid any characters other than ASCII. For example we have at least three Russian encodings and it is acceptable only because we have no choice: we face the fact that we have lots of encodings.
