Hi ToddAndMargo, Thanks for the effort to improve the Raku docs. However, this is a Raku not OO (Object Oriented ) related tutorial. As JJ already pointed out, these pages are to show the reader how you get things done in Raku, not what OO

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 Knowled

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 vi

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 not

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: bui

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 03

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 trid { } > > > it look
