Wx::Scintilla(3) Scintilla source code editing component for wxWidgets

SYNOPSIS


#----> My first scintilla Wx editor :)
package My::Scintilla::Editor;
use strict;
use warnings;
# Load Wx::Scintilla
use Wx::Scintilla (); # replaces use Wx::STC
use base 'Wx::Scintilla::TextCtrl'; # replaces Wx::StyledTextCtrl
use Wx qw(:everything);
use Wx::Event;
# Override the constructor to Enable Perl support in the editor
sub new {
my ( $class, $parent ) = @_;
my $self = $class->SUPER::new( $parent, -1, [ -1, -1 ], [ 750, 700 ] );
# Set the font
my $font = Wx::Font->new( 10, wxTELETYPE, wxNORMAL, wxNORMAL );
$self->SetFont($font);
$self->StyleSetFont( Wx::Scintilla::STYLE_DEFAULT, $font );
$self->StyleClearAll();
# Set the various Perl lexer colors
$self->StyleSetForeground( 0, Wx::Colour->new( 0x00, 0x00, 0x7f ) );
$self->StyleSetForeground( 1, Wx::Colour->new( 0xff, 0x00, 0x00 ) );
$self->StyleSetForeground( 2, Wx::Colour->new( 0x00, 0x7f, 0x00 ) );
$self->StyleSetForeground( 3, Wx::Colour->new( 0x7f, 0x7f, 0x7f ) );

$self->StyleSetForeground( 18, Wx::Colour->new( 0x7f, 0x7f, 0x00 ) );
$self->StyleSetBold( 12, 1 );
$self->StyleSetSpec( Wx::Scintilla::SCE_H_TAG, "fore:#0000ff" );
# set the lexer to Perl 5
$self->SetLexer(Wx::Scintilla::SCLEX_PERL);
return $self;
}
#----> DEMO EDITOR APPLICATION
# First, define an application object class to encapsulate the application itself
package DemoEditorApp;
use strict;
use warnings;
use Wx;
use base 'Wx::App';
# We must override OnInit to build the window
sub OnInit {
my $self = shift;
my $frame = Wx::Frame->new(
undef, # no parent window
-1, # no window id
'My First Scintilla Editor!', # Window title
);
my $editor = My::Scintilla::Editor->new(
$frame, # Parent window
);
$frame->Show(1);
return 1;
}
# Create the application object, and pass control to it.
package main;
my $app = DemoEditorApp->new;
$app->MainLoop;

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 <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 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.

MANUAL

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

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 <http://wiki.wxperl.info/w/index.php/Mac_OS_X_Platform_Notes> for more information.

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+.
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.
Release 2.20
Perl folder works for array blocks, adjacent package statements, nested PODs, and terminates package folding at DATA, D and Z.
Release 1.79
Perl lexer bug fixed where previous lexical states persisted causing ``/'' special case styling and subroutine prototype styling to not be correct.
Release 1.78
Perl lexer fixes problem with string matching caused by line endings.
Release 1.77
Perl lexer update.
Release 1.76
Perl lexer handles defined-or operator "".
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.
Release 1.71
Perl lexer allows UTF-8 identifiers and has some other small improvements.
