newguy I have downloaded and installed Rakudo on my Vista computer. How do I "compile" a .pl file? 13:49
moritz with perl6 yourfile.pl it is compiled and immediately executed 13:50
PerlJam newguy: perl6 file.pl
newguy > perl6 samtest.pl Could not find sub &samtest 13:51
I am using the perl6.exe black window to do this? 13:52
moritz nope
start a command window
and there type perl6 sametest.pl
newguy msdos?
moritz yes 13:53
or you can associate .pl files with the perl6 binary
then you can just double-click the file in the windows explorer
PerlJam newguy: What is your intent in learning Perl 6? Just for fun? 13:54
newguy to create a batch of text files changing variables in each one.

newguy OK, my results c:\Perl\bin>perl6 samtest.pl 'perl6' is not recognized as an internal or external command, operable program or batch file. 13:58
moritz since it probably didn't install into c:\Perl\bin you need to add the install location to %PATH% 13:59

Kharec on parrot, by example?
It's on parrot which I want to work.

moritz newguy: my $file = open($filename, :w); $file.say("new line"); $file.close; 17:08
masak moritz++
moritz newguy: the .close is important, otherwise the file might not get written at all
(which is a bug in rakudo, but one that's not easily fixed)
masak there are no guarantees for timely DESTROY, or even that DESTROY is called at all. 17:09
moritz not a good language for world destruction :-)
newguy moritz: so i need to define variable $file above that line right? 17:10
moritz newguy: no, just $filename
or just use a literal string there 17:11
sorear Why isn't the hash sigil #?
newguy moritz: ok will try now
moritz the 'my' already declares the $file variable
sorear: because that's for comments :-)
masak my $file = open('README', :w);
moritz NOOO
don't override the README file! :-)
sorear I've seen other characters besides # used for comments
masak no-one reads it anyway :P
newguy moritz: so what would be the file name that is created in my directory?
moritz newguy: if you have my $filename = 'output.txt'; the the file will be called output.txt 17:12
sorear #, %, *, \, ", ', ;, : I think are all the end-of-line comment chars I've seen
moritz sorear: I think the mapping from symbol to meaning is primarily historical, and less bound to the name of the symbol 17:14

sorear tadzik: ~10 years ago Perl 6 was much more APLy
tadzik sorear: APLy? 17:20
masak really?
we've gotten *more* metaops since then.
I'd say 10 years ago, Perl 6 was a lot more like Perl 5. 17:24
17:26 mberends left, mberends joined
sorear AIUI, early Perl 6 relied on Unicode operators for a lot of stuff 17:28
masak oh, that's what you meant. yes. 17:29
there was the yen symbol for zipping, for example.
17:29 ymasory_ left
masak but you could also use a 'Y', I think. 17:29
sorear how would that interact with unspace? 17:30
17:30 cdarroch joined, cdarroch left, cdarroch joined
sorear aren't the yen and backslash encoded ambiguously in a lot of Japanese encodigng? 17:30
masak not sure how that'd work out.
17:31 newguy left
PerlJam masak: 10 years ago Perl 6 was a lot more like Perl 5 .... along which axes? ;) 17:33
masak PerlJam: syntax-wise, for example.
PerlJam: also the terminology was a lot more alike. 17:34
PerlJam: look at E03, which ends by stating how little you need to change for it to be valid Perl 6.
might've been E02, I don't remember.
PerlJam Hmm.
masak it's something like "96% similar!"
PerlJam I think I agree. 17:35
aside from the Regex revamp, Perl 6 was a lot like Perl 5 back then
masak ...which makes sense, of course.
PerlJam and if you compare Perl 6 then with Perl 5 *now* they were even *more* similar 17:36
moritz modulo sigl invariance
masak :)
and parens.
