Re: Perl 6, arrays, hashes, subroutines & basic file IO

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I am wondering if you can help me a bit on output data to a file. Here is my code:

use v6;
my $aa = <A L C>;
my $peplen = 4;
.print for [X]('>', $aa xx $peplen);
my $filename = "amino_acid.txt";
my $op = open $filename, :a;
$op.print for [X]('>', $aa xx $peplen);
$op.close;

I can see the result on my command prompt, but can't see anything on my text file. Any help or suggestions will be greatly appreciated it. Thank you!!

I respond more directly to your post below but first: This site (PerlMonks) is almost entirely about Perl 5. You're in the right place if your focus is using or developing Perl 5. In contrast, for now, Perl 6 users and developers are generally better off visiting the IRC channel #perl6 on freenode. On #perl6 you'll find p6 experts happy to help beginners most hours of the day. Start by verifying that you have an up to date Perl 6 (#perl6ers will show you how to check) and then explain to #perl6 what you want to do with Perl 6 long term and what you are trying to do with the code you've quoted. In case it helps I'll cover a couple things here at PerlMonks. Running your code as it is with a current Rakudo Perl 6 errors out with: SORRY! === Error while compiling Malformed initializer at ------> $aa = ; Fixing that and recompiling gives: invoke() not implemented in class 'X' So, what is X? To see the gist of something use .gist: .print for X.gist which returns: (X) This is the gist of package X i.e. not what you meant. So, time to visit #perl6. :) Hth. the celebrity tell-all of the Perl-6 cult	[reply]

Error while compiling
Malformed initializer at ------> $aa = ;

Fixing that and recompiling gives:

invoke() not implemented in class 'X'

So, what is X? To see the gist of something use .gist:

.print for X.gist

which returns:

(X)

This is the gist of package X i.e. not what you meant. So, time to visit #perl6. :)

Hth.
