Re: [perl #131737] [BUG] WindowsOS: IO.dirname strips off drive name

'dirname' represents a component of a path, not a path. I suspect the internal field components should be renamed, though, as people do not generally think in terms of the implementation of the shell's 'dirname', but instead of its effective behavior. (The implementation splits a path into its comp

Re: String to array problem

Nested quotes and escapes are handled by the Grammar-based solution I pointed to. You can't handle them in general with a simple regex. On Sun, Jul 16, 2017 at 8:54 PM, ToddAndMargo wrote: > > -Original Message- >> From: ToddAndMargo [mailto:toddandma...@zoho.com] >> Sent: Sunday, July 1

And this is another reason for the Grammar solution: it lets you do just what is needed, in a constrained environment so you don't have any risk (unless you do something questionable in the Grammar, but then that's on you.) On Mon, Jul 17, 2017 at 6:15 AM, Brent Laabs wrote: > Just to make it cl

Re: split and one liner problem

That's a weird thing to do. You call a function that returns the lines of input as a list, in a context that joins them back together as words, and then try to split the result on lines again. lines already gives you what you want. Don't split. perl6 -e 'for lines { say "<$_>"; }' On Friday, Aug
