Re: Ping JJ: string literals

Todd (and others), So a few things. 1) JJ's example worked by chance. (sorry JJ). It worked because it just so happens that either his OS zero filled the block he was allocated by the allocator or because he didn't reuse the block that was given to him initially by the allocator. 2) If you assu

Re: bitwise NOT

If you read the signature for +^, you'll notice it returns an Int. In your first working example, you're taking a uint8 with binary value 10100101, zero extending it to 64 bits via +^, applying a two's compliment, and then assigning bits [0:7] to another uint8 which at that point contains the bin

Dynamic export/import of symbols into global namespace

As the subject suggests, I'd like to dynamically export/import symbols from a source file into the global scope of the program. How would one accomplish this? Given the below, it yields an error _which I expect_. How do I dynamically pull in the subset 'What'? File: Testing.pm6 ---

Was talking to folks over on the #perl6 IRC channel. It appears the recommended way is: sub matching_chars(Str $chars_to_match, Str $str) { # warnings, treats as string not variable $str ~~ /<$_>/ given "<[$chars_to_match]>"; } ~Paul On Sat, Aug 31, 2019 at 9:54 PM yary wrote: > I fou

Re: Variable character class

I'm not entirely sure if this is the correct answer, but if you define your own custom character class with a 'regex' object, you can use that in the grouping. sub matching_chars(Str $chars_to_match, Str $_) { my regex x { $chars_to_match ** 1 }; m/<[]>/; } The above worked for me in the
