"say" uses the .gist method, which quotes the output for readability. You probably want "put" instead. On Sun, Jun 3, 2018 at 8:42 PM Xin Cheng wrote: > Hi, > > I am trying to make a program to do grep with perl6 regular expression, > and I would like to colorize the matched part to the

Re: need second pair of eyes

I'm still trying to figure out why you have just "lib" instead of "use lib" there. And why it's not throwing an error. On Sun, Jun 3, 2018 at 6:02 PM ToddAndMargo wrote: > On 06/03/2018 02:50 PM, Brandon Allbery wrote: > > Double quotes, or the one we were just

Same answer: https://docs.perl6.org/type/IO::Path is where all the path-related things live. On Sun, Jun 3, 2018 at 1:05 PM ToddAndMargo wrote: > Hi All, > > I need the Perl6 commands for the following LINUX > commands. > > mkdir make directory > chown change ownership > chmod

Re: IO ???

It's a bit subtle to track down, but the IO method gives you an IO::Path object. https://docs.perl6.org/type/IO::Path On Sun, Jun 3, 2018 at 1:01 PM ToddAndMargo wrote: > Hi All, > > I have a been looking around the docs pages and I am > not finding a list of what the various IO functions do. >

Re: need second pair of eyes

bash doesn't like nested single quotes, even with escapes. So the first \' gave you a literal backslash and ended the quoted part, then the second \' gave you a literal ' and continued without quoting. The final ' would then open a new quoted string, but bash doesn't get that far because it sees

Re: my keeper on random numbers

In the long form, yes. That's why the ^ shorthand exists. With the long form you have to start from an object of the same type to get to its metamodel, then pass the object you're actually asking about to the metamodel method; the simplest way to do this is to reuse the same object. On Sun, May
