Access violation when creating class instance

Hi all, I have an access violation on Windows for one of my classes and think it is a bug, but not entirely sure about that. Every now and then creating a class instance ended my script with error: Process finished with exit code -1073741819 (0xC005) The class looks like that: class

Re: fill in form

Years ago I played around with qt and GTK::Simple. It works fine, but the installation process on Windows is poor, to say at least. It might be not better, but you could use the PowerShell to show a GUI and store something in a txt file you then parse. On Tue, 12 May 2020 at 10:22, ToddAndMargo

Raku -npe command line usage

Hi, I am trying to write an one-liner to go through all lines in a logfile and look for an certain key word, store the line and sort them before printing them out. My approach was: raku -ne "BEGIN {my @i }; @i.push($_); if $_ ~~ /^WARN/; END { @i.sort.say }" That does not work because @i does

Re: printf question

Interesting stuff. I would like to take the change and ask one question: One thing, I had to get used to is the MAIN handling of parameters. On the command line it is important to write then named parameter in front of the positional ones: MAIN('compile', :$verbose, :$test-only) needs to write:

Re: Bug to report: cardinal called an integer

Hi Todd, For years, I have been playing around with programming stuff. I never stumbled across the term "cardinal". Its obvious that I am not an native English speaker and it does not hurt to learn new stuff. But, you makes it harder to understand your problems if you not use the common jargon.

Re: Request for Enhancement: Native Call error

Hi Todd, Sounds like in WinReg.pm6 line 177 is a definition like : sub RegOpenKeyExW( DWORD, WCHARS, DWORD, DWORD, DWORD is rw) is native("Kernel32.dll") returns DWORD { * }; and you put a "my $i = 0" variable instead of "my int32 $i = 0" in it somewhere. Greetings, Wolf On Wed, 1 Jan 2020 at

I would love to look into that, however, my son needs all my free time and I do have very little knowledge about NativeCall. I hope I will find time in the next days to learn more of this stuff, but I will not much help :-( On Fri, 27 Dec 2019 at 07:31, ToddAndMargo via perl6-users <

Multibyte string in Windows command line

Hi all, My perl6 runs an executable and prints its output. This output is printed as multibyte string. I assume the executable gives back a multibyte string and perl6 interpret its as one byte string for whatever reasons. I tried Run with different encodings like windows-1251, utf16 and so on. No

Well spotted. I totally muss that. However, that was not the only mistakes I did. Another problem is to use # commentaries in grammars. Which causes also the exception. Thanks for the help! On 4 August 2017 at 08:22, yary wrote: > Is this line intentional? > > token

Hi all, I am writing a script to compare to text file. More precisely, certain data is compared not line by line. To find this information I use grammars. At the beginning it worked great. But then, my script hangs. Started with the debugger perl6-debug-m I got this exception: Unhandled
