=head1 NAME

App::VOJournal - call Vimoutline on a journal file.

=head1 VERSION

Version v0.4.6

=cut

use version; our $VERSION = qv('v0.4.6');

=head1 SYNOPSIS

Open a file in vimoutliner to write a journal

    use App::VOJournal;

    App::VOJournal->run;

or, on the command line

    perl -MApp::VOJournal -e App::VOJournal->run

=head1 SUBROUTINES/METHODS

=head2 run

This is the only function you need to use this Module. It parses the command
line and determines the date for which you want to write a journal entry.
Then it makes sure all necessary directories are created and starts
vimoutliner with the journal file for that date.

    use App::VOJournal;

    App::VOJournal->run;

=head1 COMMANDLINE OPTIONS

=head2 --basedir $dir

Use C<< $dir >> instead of C<< $ENV{HOME}/journal >> as base directory for
the journal files.

=head2 --date [YYYY[MM]]DD

Use a different date than today.

One or two digits change the day in the current month.

Three or four digits change the day and month in the current year.

Eight digits change day, month and year.

The program will not test for a valid date. That means, if you specify
'--date 0230' on the command line, the file for February 30th this year
would be opened.

=head2 --editor $path_to_editor

Use this option to specify an editor other than C to edit
the journal file.

=head2 --[no]header

Normally every journal file starts with some header lines, indicating the
day the journal is written.

If the option C<--noheader> is given on the command line, this header lines
will be omitted.

=head2 --[no]resume

Look for open checkboxes in the last journal file and carry them forward
to this days journal file before opening it.

This only works if there is no journal file for this day.

The default is C<< --resume >>

=head2 --version

Print the version number and exit.
