I'm afraidr that won't last.

Due to the many bugs (debuggger test don't work with recent perl), and lack of 
stability (random crashes), I've given up on maintaining padre for Debian last 
year and requested its removal from Debian. 

Since Ubuntu uses padre Debian package, I'm afraid that padre will not be 
shipped on Ubuntu in the next future.

All the best

You know what, never mind on this.  I will use Inline instead.

Class Display has no attributes, which is illegal with
the CStruct representation.

What in the world?


It's an opaque pointer; CStruct is the wrong representation to use. Try
CPointer instead.



Hi Brandon,

The example over at:
http://rosettacode.org/wiki/Window_creation/X11#Perl_6
is a complete syntax mess.

Could I talk you into debugging it?

Oh poop I have a lot of reading to do.  Found a
great example over at:

http://rosettacode.org/wiki/Window_creation/X11#Perl_6
I will start with reading what my display is (:0.0).

And I didn't get far trying to run the example:


class Display is repr('CStruct') {}


Class Display has no attributes, which is illegal with
the CStruct representation.

What in the world?

Yes.

Also this is a particularly ugly hack (among other things: this is why
nobody realizes X11 can clipboard *any* data, not just text. But if you go
through the ancient cutbuffer stuff, simple text is all you get).

Hi All,

In Linux, how do I call system functions from Perl 6?

int XStoreBytes(Display *display, char *bytes, int nbytes);

And what is that?  "C"?

Is there an inline "C" call?

Many thanks,

Thank you!

Re: How do I call system functions?

[Will Coleda]

Perl 6 uses "NativeCall" to call out to native library functions. I
would start with

https://docs.perl6.org/language/nativecall

and come back with specific questions.

Re: How do I use "&?ROUTINE"?

[Brent Laabs]

You must be doing something wrong then:

> sub LinuxCheck () { print &?ROUTINE.name ~ " " ~ "$*DISTRO OS\n"; }
sub LinuxCheck () { #`(Sub|140478449412680) ... }
> LinuxCheck();
LinuxCheck macosx OS
