Re: printf question

Here's one way my uint8 $u = 0x4F; say '$u = <0b' ~ '%08b'.sprintf($u).comb(/\d ** 4/).join('_') ~ '>;'; There's probably others as well. On Mon, Feb 3, 2020 at 8:17 PM ToddAndMargo via perl6-users < perl6-users@perl.org> wrote: > On 2020-02-03 13:51, ToddAndMargo via perl6-users wrote: >

Re: printf question

I think you need a more specific question... p6 'my uint8 $u = 84; printf "\$u = <_%04s>\n", $u;' -y On Mon, Feb 3, 2020 at 3:52 PM ToddAndMargo via perl6-users < perl6-users@perl.org> wrote: > Hi All, > > Is ther a way to get > > $ p6 'my uint8 $u = 84; printf "\$u = <%08s>\n", $u;' > $u

Hi All, Is ther a way to get $ p6 'my uint8 $u = 84; printf "\$u = <%08s>\n", $u;' $u = <0084> to print $u = <_0084> ? Many thanks, -T

Can perl6 manage C Pointer directly? that would be amazing really. regards. On Mon, Feb 3, 2020 at 7:35 PM Aureliano Guedes wrote: > Also, this is amazing: > https://docs.raku.org/language/nativecall#sub_nativecast > > > > On Mon, Feb 3, 2020 at 8:32 AM Aureliano Guedes < >

Re: perl6 with XS

This is nice. Sorry for my ignorance but what is the advantage in use CArray instead of a usual raku array? https://docs.raku.org/language/nativecall#CArray_methods On Mon, Feb 3, 2020 at 12:41 AM Darren Duncan wrote: > Raku has the Native Call interface >
