perl6

Is it possible to use junction to match any of the values in a junction? I want to match any of the values in an array. What is the proper way to do it? lisprog$ perl6 To exit type 'exit' or '^D' > my @a=<a b c> [a b c] > any(@a) any(a, b, c) > my $x=any(@a) any(a, b, c) > my $y = "a 1" a 1 > say $y ~~ m/ $x / False > say $y ~~ m/ "$x" / False > my $x = any(@a).Str any("a", "b", "c") > say $y ~~ m/ $x / False > say $y ~~ m/ || $x / False > say $y ~~ m/ || @a / ｢a｣ > Thanks !! Junctions are not meant to be interpolated into regexes. They're meant to be used in normal Perl 6 expressions,

Functions can be called in a couple ways: say(1, 2, 3) # 123 say: 1, 2, 3 # (1, 2, 3) The latter seems to pass a Positional , but apart from that I don't know how else they differ. Are there any differences that are important to know? What types of situations would you use one over the other? jjmerelo As Raiph tells you above, say: is a label. So you didn't say anything (even though you thought you did) and -- outside use of the REPL -- the compiler will complain that your use of <a b c> was useless: say: <a b c>; # OUTPUT: «WARNINGS for <tmp>:␤Useless use of constant value a b c in sink

I am starting to write BibTeX parser. The first thing I would like to do is to parse a braced item. A braced item could be an author field or a title for example. There might be nested braces within the field. The following code does not handle nested braces: use v6; my $str = q:to/END/; author={Belayneh, M. and Geiger, S. and Matth{\"{a}}i, S.K.}, END $str .= chomp; grammar ExtractBraced { rule TOP { 'author=' <braced-item> .* } rule braced-item { '{' <-[}]>* '}' } } ExtractBraced.parse( $str ).say; Output : ｢author={Belayneh, M. and Geiger, S. and Matth{\"{a}}i, S.K.},｣ braced-item => ｢

Last week I decided to give a try to Perl6 and started to reimplement one of my program. I have to say, Perl6 is so the easy for object programming, an aspect very painfull to me in Perl5. My program have to read and store big files, such as whole genomes (up to 3 Gb and more, See example 1 below) or tabulate data. The first version of the code was made in the Perl5 way by iterating line by line ("genome.fa".IO.lines). It was very slow and unsable for a correct execution time. my class fasta { has Str $.file is required; has %!seq; submethod TWEAK() { my $id; my $s; for $!file.IO.lines ->
