Perl 6 interface to the IUP toolkit for building GUI's.


Perl 6 interface to the IUP toolkit. IUP is a multi-platform toolkit for building graphical user interfaces. IUP's purpose is to allow a program source code to be compiled in different systems without any modification. Its main advantages are:

  • it offers a simple API.
  • high performance, due to the fact that it uses native interface elements.
  • fast learning by the user, due to the simplicity of its API.


You will need the Linux libraries libiup and libiupimglib installed in order to use perl6-IUP (version 3). You can download the library binaries or sources for your platform from here.

To install with the Panda tool.

panda update
panda install IUP

To run a script that uses the IUP library.

PERL6LIB=$HOME/.perl6/2013.02.1/lib LD_LIBRARY_PATH=$HOME/.perl6/2013.02.1/lib ./hello.p6


WARNING: This module is Work in Progress and is in a early stage, which means: this interface is not final. This will perhaps change in the future.
A sample of the code can be seen below.

Hello World IUP Application

use IUP;

my @argv = ("Test");

# initialize iup

my $iup =;


# create widgets and set their attributes

my $btn = $iup.button("&Ok", "");

$btn.set_callback("ACTION", &exit_callback);

$btn.set_attribute("IMAGE", "IUP_ActionOk");
$btn.set_attribute("EXPAND", "YES");
$btn.set_attribute("TIP", "Exit button");

my $lbl = $iup.label("Hello, world!");

my $vb = $iup.vbox($lbl, $btn);
$vb.set_attribute("MARGIN", "10x10");
$vb.set_attribute("GAP", "10");
$vb.set_attribute("ALIGNMENT", "ACENTER");

my $dlg = $iup.dialog($vb);
$dlg.set_attribute("TITLE", "Hello");

# Map widgets and show dialog


# Wait for user interaction


# Clean up



sub exit_callback() returns Int {
	return IUP_CLOSE;
