I need `dir` help

Hi All, https://docs.perl6.org/routine/dir perl6 -e 'my $x=dir; say "$x";' Does indeed read the directory, but give me one YUGE string. I need each entry to have some kind of a separator. Many thanks, -T -- ~~ Computers are like air conditioners. They

Re: I need `dir` help

i'm afraid you didn't read the docs very closely... Returns the contents of a directory as a lazy list of IO::Path objects stringifying an IO::Path object gives you a large string. the examples in the docs take up more room than the description of the routine. here's the first: Examples: > #

I think you'll need to provide a better explanation of what you're trying to accomplish. I can think of lots of ways to do useful things with the output of dir(), but have no idea which one(s) you need. On Thu, May 10, 2018 at 7:52 PM, ToddAndMargo wrote: > On 05/10/2018

I need indir help

Hi All, I am over on https://docs.perl6.org/routine/indir I can make heads of tails out of what is going on. I want to check is a file exists. $ perl6 -e 'say indir("./EchoTest");' ===SORRY!=== Error while compiling -e Calling indir(Str) will never work with any of these multi signatures:

Re: I need indir help

Testing whether a file exists is smartmatching an IO::Path (or a Str that gets coerced to one) against :e. "indir" is not "is this file in this directory?", it's "run this code in this directory instead of where I am now". So it's complaining that you didn't tell it what code to run there. On

Re: I need regex help

Pretty much what it's telling you. Instead of the numbers in braces, it's the ** operator with a range after it: \d ** 1..4 (Remember that spaces do nothing in a P6 regex, so you can use them for readability or to separate the range from what follows, etc.) On Thu, May 10, 2018 at 11:56 PM,
