Re: buf to integer?

Unpack is very useful if you have multiple items you want to unpack, and if you're familiar with the Perl 5 unpack then there's the P5pack module (which isn't a full implementation of Perl 5's unpack, but is useful for simpler things). If you want to unpack something from the middle of a Buf or Blo

What is a LoweredAwayLexical?

Yesterday I created a new when clause in an existing working program, which worked fine, but today when I came to exercise another previously working when clause it was broken. The golfed version... my $a = 41; given 6 { when 5 { my $a; } when 6 { say $a + 1; } }

Re: problems with xor

As you say, +^ is an infix operator. Why are you trying to use it as a function? Try $z = $x +^ $y. On Sat, 18 Jan 2020 at 15:03, ToddAndMargo via perl6-users < perl6-us...@perl.org> wrote: > Hi All, > > https://docs.raku.org/routine/+$CIRCUMFLEX_ACCENT > > (Operators) infix +^§ > > multi sub in

Re: problems with xor

In Raku, all operators are just functions with a funny syntax, but if you want to use it as a function, you need the full name. infix:<+^>($x, $y) would probably work just as well. And where is the '$' before the z? On Sat, 18 Jan 2020 at 15:45, ToddAndMargo via perl6-users < perl6-us...@perl.or

Re: problems with xor

As has been explained quite explicitly twice already, you call it as a sub by using the full explicit name of the subroutine: $z = infix:<+^>($x, $y) On Sun, 19 Jan 2020 at 07:22, ToddAndMargo via perl6-users < perl6-us...@perl.org> wrote: > On 2020-01-18 06:09, Tobias Boege wrote: > > On Fri,

There's no need to ask essentially the same question three times. https://docs.raku.org/routine/range is quite clearly the wrong page. That's about a method on the class X::OutOfRange, and not a method on Int. You want https://docs.raku.org/routine/Range, whic

Re: printf question

The "workaround" is well documented: https://docs.raku.org/language/create-cli#%*SUB-MAIN-OPTS It's just a matter of setting named-anywhere option in the %*SUB-MAIN-OPTS hash, which you will also need to create. There's an example in that doc page. Kevin. On Tue, 11 Feb 2020 at 20:07, WFB wrote

Re: Question about Blob and Buf

~ works fine for concatenating Bufs; For example: my $a = Buf.new(1,2,3); my $b = $a ~ Buf.new(4,5,6) will assign correctly to $b. I can't work out what the problem is here, despite trying various combinations. Perhaps socket isn't really returning a Blob? Kevin. On Tue, 11 Feb 2020 at 21:01,

Re: 'CALL-ME' Math problem?

Just because mathematics allows an implied multiplication doesn't mean Raku does -- in fact I can't think of any programming language which does. You need to stick an explicit multiplication operator ('*' or '×') between the 5 and the left parenthesis. The reason for the error message is that addi

You can still use the Perl 5 module from Raku without writing any Perl code. It should allow a fairly seamless update to a usable Raku module when one becomes available. On Fri, 22 Oct 2021, at 16:18, ToddAndMargo via perl6-users wrote: > On 10/21/21 22:03, Kevin Pye wrote: >

You don't. sqrt is a function which acts on 64-bit floating point numbers, and there's no more meaningful digits available. If you need more precision you're on your own. On Mon, 1 Nov 2021, at 11:20, ToddAndMargo via perl6-users wrote: > On 10/31/21 16:42, ToddAndMargo via perl6-users wrote: >>
