=head1 SYNOPSIS

	$> perl asciio.pl

=head1 DESCRIPTION

It has always been painful to do ASCII diagrams by hand. This perl application allows 
you to draw ASCII diagrams in a modern (but simple) graphical interface.

The ASCII graphs can be saved as ASCII or in a format that allows you to modify them later.

Special thanks go to the Muppet and the gtk-perl group, Gabor Szabo for his help and advices.

Adam Kennedy coined the cool name.

Press 'F1' for help.

=head2 context menu

The context menu allows one to access to B<Asciio> commands.

=head2 keyboard shortcuts

All the keyboard commands definitions can be found under I<asciio/setup/actions/>. Among the commands
implemented are:

=over 2

=item * select all

=item * delete

=item * undo

=item * group/ungroup

=item * open / save

=item * local clipboard operations

=item * send to front/back

=item * insert arrow, boxes, text

=item * ...

=back

The available commands are displayed if you press B<K>. 

=head2 elements

There are a few elements implemented at the moment.

=head3 wirl arrow

An arrow that tries to do what you want. Try rotating the end clockwise then counter clockwise to see how it acts

               ^
               |
               |    --------.
               |            |
               '-------     |
                            |
 O-------------X     /      |
                    /       |
                   /        |
                  /         v
                 /
                /
               v
	       

=head3 multi section wirl arrow

A set of whirl arrows connected to each other

 .----------.                       .
 |          |                \     / \
    .-------'           ^     \   /   \
    |                    \     \ /     \
    |   .----------->     \     '       .
    |   '----.             \           /
    |        |              \         /
    '--------'               '-------'
    


=head3 angled arrow and axis

   -------.         .-------
           \       /
            \     /
             \   /
 
             /   \
            /     \

          ^

        / |\
       /  | \
      /   |  \
     v    |   v
          v
	

=head3 box and text 

                 .----------.
                 |  title   |
  .----------.   |----------|   ************
  |          |   | body 1   |   *          *
  '----------'   | body 2   |   ************
                 '----------'
                                             anything in a box
                                 (\_/)               |
         edit_me                 (O.o)  <------------'
                                 (> <)
				 

You can also use the 'External commands in box' to direct an external command output to a box. Default shortcuts are 'x' and CTL + 'x'.

=head3 "if" box and "process" box

                        ____________
   .--------------.     \           \
  / a == b         \     \           \   __________
 (    &&            )     ) process   )  \         \
  \ 'string' ne '' /     /           /    ) process )
   '--------------'     /___________/    /_________/
   

=head3 your own stencils

Take a look at I<setup/stencils/computer> for a stencil example. Stencils listed in I<setup/setup.ini> will
be loaded when B<Asciio> starts.

=head3 your own element type

For simple elements, put your design in a box. That should cover 90% of anyone's needs. You can look in 
I<lib/stripes> for element implementation examples.

=head2 exporting to ASCII

You can export to a file in ASCII format but using the B<.txt> extension.

Exporting to the clipboard is done with B<ctl + e>.

=head1 DEPENDENCIES

gnome libraries, gtk, gtk-perl for the gtk version

=head1 BUGS AND LIMITATIONS

Undoubtedly many as I wrote this as a fun little project where I used no design nor 'methodic' whatsoever.

=head1 AUTHOR

=head1 LICENSE AND COPYRIGHT

This program is free software; you can redistribute
it and/or modify it under the same terms as Perl itself.

=head1 SUPPORTED OSes

=head2 Gentoo

I run gentoo, packages to install gtk-perl exist. Install Asciio with cpan.

=head2 FreeBSD

FreeBSD users can now install asciio either by package:

$ pkg_add -r asciio

or from source (out of the ports system) by:

$ cd /usr/ports/graphics/asciio
$ make install clean

Thanks to Emanuel Haupt.

=head2 Ubuntu and Debian

Ports are on the way.

=head2 Windows

B<Asciio> is part of the B<camelbox> distribution and can be found here: L<http://code.google.com/p/camelbox/>. Install, run AsciiO from the 'bin' directory.

 '-------------------------------'

B<camelbox> is a great distribution for windows. I hope it will merge with X-berry series of Perl distributions.

=head1 Mac OsX

This works too (and I have screenshots to prove it :). I don't own a mac and the mac user hasn't send me how to do it yet.

=head1 other unices

YMMV, install gtk-perl and AsciiO from cpan.
