Re: trouble returning a value from sub

I think, and I don't have my computer to hand to double check but I think you want a return before your recursive.call to factors passing in @f. When dealing with recursive functions you need to make sure what you're returning back up the stack. On Thu, 16 Jun 2022, 18:10 Rick Bychowski,

Re: need s/ help

So what you what to match is a followed by zero or more not a's and then the end of the string. <[a]> is the perl6 regex for a range comprising of a alone you can negate that like so <-[a]> Giving us perl6 -e 'my $x="abcabcabc"; $x ~~ s/a <-[a]>* $/xyz/; say $x;' (There's probably a better

User defined infix operators and whitespace

So I had a crazy little idea. I've played the odd bit of roleplaying in my time and wanted to created a 'd' operator. Quite simple really. sub infix: ( Int $num, Int $size ) { [+] (1..$size).roll($num) }; sub prefix: ( Int $size ) { 1 d $size } Gives us 3 d 6 to roll 3 six sided dice or a

Possible zef addition

So I'm playing around with Docker files (Perl 5 ATM) and one thing I'm getting quite into is trying to keep them small. An important part of this is deleting any extraneous caching info built up during the build, preferably as part of the RUN step to get intermediate layers small. (So with Perl5

Re: How to I create a file?

.e checks a path exists. .f checks it exists AND is a file. .d checks it exists AND is a directory. (Perl 5 was the -e, -f and -d tests) On Tue, 21 Mar 2017 at 10:19 ToddAndMargo wrote: > On 03/21/2017 03:07 AM, Brent Laabs wrote: > > You can create a file by opening a

Re: Is this file check backwards?

Just because the file is called "nonexistent_file" doesn't mean is doesn't exist. It's a poorly written example really. if "possibly_existing_file".IO.e { say "file exists"; } else { say "file doesn't exist"; } Is more intuitive I would say. On Tue, 21 Mar 2017 at 09:53 ToddAndMargo
