=head1 DESCRIPTION

While we already have a good scintilla editor component support via 
Wx::StyledTextCtrl in Perl, we already suffer from an older scintilla package 
and thus lagging Perl support in the popular Wx Scintilla component. wxWidgets 
L<http://wxwidgets.org> has a *very slow* release timeline. Scintilla is a 
contributed project which means it will not be the latest by the time a new 
wxWidgets distribution is released. And on the scintilla front, the Perl 5 lexer 
is not 100% bug free even and we do not have any kind of Perl 6 support in 
Scintilla.

The ambitious goal of this project is to provide fresh Perl 5 and maybe 6 
support in L<Wx> while preserving compatibility with Wx::StyledTextCtrl
and continually contribute it back to Scintilla project.

Note: You cannot load Wx::STC and Wx::Scintilla in the same application. They
are mutually exclusive. The wxSTC_... events are handled by one library or
the other.

Scintilla 2.28 is now bundled and enabled by default.

=head1 MANUAL

If you are looking for more API documentation, please consult L<Wx::Scintilla::Manual>

=head1 PLATFORMS

At the moment, Linux (Debian, Ubuntu, Fedora, CentOS) and Windows (Strawberry
and ActivePerl)  are supported platforms. My next goal is to support more 
platforms. Please let me know if you can help out :)

On Debian/Ubuntu, you need to install the following via:

    sudo apt-get install libgtk2.0-dev

On MacOS 64-bit by default you need to install a 32-bit Perl in order to
install wxWidgets 2.8.x. Please refer to 
L<http://wiki.wxperl.info/w/index.php/Mac_OS_X_Platform_Notes> for more information.

=head1 HISTORY

wxWidgets 2.9.1 and development have Scintilla 2.03 so far. I searched for Perl lexer
changes in scintilla history and here is what we will be getting when we upgrade to
2.26+.

=over

=item Release 2.26

Perl folding folds "here doc"s and adds options fold.perl.at.else and
fold.perl.comment.explicit. Fold structure for Perl fixed. 

=item Release 2.20

Perl folder works for array blocks, adjacent package statements, nested PODs,
and terminates package folding at DATA, D and Z.

=item Release 1.79

Perl lexer bug fixed where previous lexical states persisted causing "/" special 
case styling and subroutine prototype styling to not be correct.

=item Release 1.78

Perl lexer fixes problem with string matching caused by line endings.

=item Release 1.77

Perl lexer update.

=item Release 1.76

Perl lexer handles defined-or operator "".

=item Release 1.75

Perl lexer enhanced for handling minus-prefixed barewords, underscores in
numeric literals and vector/version strings, D and Z similar to END, subroutine 
prototypes as a new lexical class, formats and format blocks as new lexical
classes, and '/' suffixed keywords and barewords.

=item Release 1.71

Perl lexer allows UTF-8 identifiers and has some other small improvements.
