RE: return code?

Todd, I see that you’re frequently running commands in your code like me. I was looking for a reliable reusable approach for commands for a long time. I’m still learning & not quite ready to step up to contribute to the ecosystem yet (https://docs.perl6.org/language/modules.html). After

Re: return code?

Yes, that's what I was addressing: you can tell run() to do that, keeping stderr separate with :err(). qxx does that internally. On Sat, Jul 28, 2018 at 4:12 PM ToddAndMargo wrote: > On 07/28/2018 12:56 PM, Brandon Allbery wrote: > > You can control where run() sends things. > > Hi Brandon, > >

If you really want a headache, go look at the revision history for vercmp() in the RPM repo. On Sat, Jul 28, 2018 at 4:08 PM ToddAndMargo wrote: > On 07/28/2018 08:26 AM, Brandon Allbery wrote: > > I think you can use Version.new on that and compare them reasonably > > directly? That said,

Re: return code?

You can control where run() sends things. See the :out and :err named parameters. I think :err($*ERR) is what you want here, although you might also want :err($*OUT) which effectively redirects its stderr to rakudo's stdout. (That said, I don't know if it processes those in the right order; it

I think you can use Version.new on that and compare them reasonably directly? That said, comparison of version numbers is a bit of a minefield for exactly this reason: not everyone agrees on when to use string vs. numeric comparison, or what to do when one is numeric and the other isn't. On Sat,

Re: return code?

I'm not sure about qqx because I too am a fledgling perl6 programmer, but the run routine returns a Proc object that has an exitcode method. my $proc = run 'ls', 'dir!'; $proc.exitcode.say; Right in the documentation the following is stated as
