=head1 NAME

Padre::Plugin::SpellCheck - Check spelling in Padre, The Perl IDE.

=head1 VERSION

version: 1.33

=head1 DESCRIPTION

For Padre 0.98

This plug-in allows one to check there spelling within Padre using
C<F7> (standard spelling short-cut across text processors).

One can change the dictionary language used (based upon install languages) in
 the preferences window via Plug-in Manager.
Note that preferences can B<only> be setup while the plugin is B<disabled>.
Preferences are persistent. You need to Save your preferred language.

This plug-in is using C<Text::Aspell> default (legacy). You can also use C<Text::Hunspell>, so check these module's
pod for more information and install the one for you.

Of course, you need to have the relevant Dictionary binary, dev and dictionary installed.


=head1 SYNOPSIS

    Check your file or selected text for spelling errors in your preferred language.

=head1 BUGS and LIMITATIONS

If you upgrade your OS, and run Perl from a local/lib,
 you may find Hunspell stops showing local dictionary in preferences,
 you will need to un-install Text::Hunspell and re-install in CPAN.


Spell-checking non-ascii files has bugs: the selection does not
match the word boundaries, and as the spell checks moves further in
the document, offsets are totally irrelevant. This is a bug in
C<Wx::StyledTextCtrl> that has some Unicode problems... So
unfortunately, there's nothing that I can do in this plug-in to
tackle this bug.

Please report any bugs or feature requests to C<padre-plugin-spellcheck
at rt.cpan.org>, or through the web interface at
L<http://rt.cpan.org/NoAuth/ReportBug.html?Queue=Padre-Plugin-SpellCheck>.
I will be notified, and then you'll automatically be
notified of progress on your bug as I make changes.
