Hi All,
I presume this is failing as the current directory is not
in the "lib" path:
$ perl6 -MPrintColors 'PrintBlue( "Blue\n" );'
Could not open PrintBlue( "Blue" ). Failed to stat file: no such
file or directory
This does work, but what a lot of extra work:
$ perl6 -e 'use lib "/home/lin
You can just put -I lib on your commandline, but what's more important
is that you forgot to pass -e, so it was taking your code and
interpreting it as a filename. It's very unlikely that you have a file
called 'PrintBlue( "Blue\n" );' in the current directory, though.
perl6 -Ilib -MPrintColors -e
Since I haven't done this for a long time, let me remind you the
possibility of posting, if you will, your questions _also_ in
StackOverflow. You'll (possibly) get more answers (or just different ones),
and will help spread the word about Perl 6 (which lately has gone back to
the usual regime of on

Please be aware that passing a folder with many files in it as the -I

goes through the whole file hierarchy starting at that path. If

Hi All,
The Perl 5 guys have it pounded into my head that I
always had to check my substitutions to see if they
worked if not working would crash the program.
So in Perl 6 I have:
$ p6 'my $x="abc"; if s/b/z/ {say "sub worked"}else{say "sub failed"};
say "$x";'
Use of uninitialized value of
You're putting your starting string in a variable, $x, but aren't
telling the s/// operator specifically what to operate on, so it
defaults to $_, which is still at its default value.

Or, store the string in $_, and take advantage of less to type-
perl6 -e '$_="abc"; say so /z/; say so /b/; s/c/defg/ ?? .say !! say
"Failed!"'

Thank you!
Well I can see it working, but what does

Perl6 Users,
The POSIX module in the ecosystem (https://github.com/cspencer/perl6-posix)
implements a few commonly used subs from POSIX IEEE Std 1003.1 in a single
file, which I found useful. I wanted to use more of these so I coded a few
simple subroutines with NativeCall for my own use. The
Many of them are already in the ecosystem as part of lizmat's Buttefly
project of porting Perl 5 CPAN modules to Perl 6. That If I remember
correctly, the ones you mention are one of the few that are missing, but
you can find most of them here: https://modules.perl6.org/search/?q=p5

Thank you. Please let me know if you miss anything and/or find any problems.
For myself, I’ve hardly had any use for these modules so they’re probably
undertested.

Liz,
I'm a "Systems" person, so I'm checking hosts/IPs/networks/users/groups/etc.

"so" coerces to True or False. "say /c/" would output the match object "say
so /c/" says True. Depends on what you want to see.
" $x ?? $y !! $z" is a shortcut - "if $x use value of $y else use value of
$z" and ought to be used for the final value.
You may know it in perl5 as "$result = $x ? $y :
