=head1 DESCRIPTION

This script downloads TV listings using Schedules Direct's data service,
converts it to XMLTV format, and outputs the results.

You must first register with Schedules Direct at: L<http://www.schedulesdirect.org>

Schedules Direct is a non-profit organization whose mission is to provide
low-cost television program guide data to end-users of Open Source
and Freeware applications.

The raw data source is Schedules Direct's SD-DD service, which purchases
Data from Gracenote (formerly known as Tribune Media Services).

While the service is not available for free, Schedules Direct strives
to keep costs as low as possible.

First you must become a member at the L<http://www.schedulesdirect.org>  site.

Next, you use that website to add lineup(s) to your account.

Next, you execute C<tv_grab_na_dd --configure> to set up the grabber.

Finally, you execute B<tv_grab_na_dd> with no arguments and it will output
listings in XML format to standard output.  See below for other options.

Like many utilities, tv_grab_na_dd tries to exit with a "0" on success and something else
on error.

=head1 Stand-alone options

=over

=item --help

Print a help message and exit.

=item --version

Show the version of the grabber.

=item --capabilities

Show which capabilities the grabber supports. For more
information, see L<http://wiki.xmltv.org/index.php/XmltvCapabilities>

=back

=head1 Mode selection (default is grab mode)

=over

=item --configure

Activates configure mode.  If a config file already exists the values
are used as defaults.

=item --gui OPTION

Use this option to enable a graphical interface to be used.
OPTION may be 'Tk', or left blank for the best available choice.
Additional allowed values of OPTION are 'Term' for normal terminal output
(default) and 'TermNoProgressBar' to disable the use of Term::ProgressBar.

=item --list-lineups

Lists available lineups.  Only requires username in the config file. Used
by programs that automate the L</--configure> process.

=back

=head1 General Options

=over

=item --config-file
I<file>

Set the name of the configuration file, the default is B<~/.xmltv/tv_grab_na_dd.conf>.
This is the file created during L</--configure> mode.

=item --dd-data
I<file>

Store raw Data Direct data to this file. (default is a temporary file)

=item --reprocess

Don't get data from Data Direct, but reprocess a file saved with L<--dd-data|/"--dd-data I<file>">.

=item --auto-config I<add|ignore>

When used in --configure mode, updates the config file, removing old channels, and adding or
ignoring new channels.  Prompts are skipped if defaults are available in the current config file.

When used in grab mode, appends new channels to the config file.

=back

=head1 Grabber Mode options

=over

=item --days I<n>

Grab I<n> days.  The default is 7.

=item --offset I<n>

Start N days after the default.

=item --quiet

Suppress some messages normally written to standard error.

=item --notrim

Data Direct includes shows in progress at the start time.  The default behavior
is to filter these shows out so data can be cleanly split between days.  This
option turns off that filter so you get shows in progress a tthe start time.

=item --old-chan-id

Use a channel id similar to the one used by the old B<tv_grab_na> grabber.

=item --low-mem

Omit all but the most basic program information. Reduces memory usage.

=item --output I<file>

Write xml to I<file> rather than standard output.

=item --list-channel

Same as B<--days> 0

=item --share I<SHAREDIR>

tv_grab_na_icons stores icons in I<SHAREDIR>/icons.  The share directory is set at install time,
but there may be times when it needs to be specified. (for example: no write access to the default share
directory)

=item --list-times

Report to STDERR the Schedules Direct blockedTime (not currently enforced)
and suggestedTime values to assist automated processes with scheduling.

=item --download-only

Don't generate any output, just fetch the data.  Personally I don't see the point,
but it was requested and easy to add.

=item --padd I<n>

Add <n> spaces to the front of the start date.  This is normally not needed,
but can be helpful in working around a SD-DD problem when the request packet
spans TCP packets.  Recommended initial value is "20".  This is only needed if you get
"invalid start time" messages.  If this helps, please post results to the list.

=item --dropbadchar

DD data is supposed to be in UTF-8 format.  Sometimes DD sends bad characters
which cause a "Bad XML from DD" error.  This option causes those bad characters
to be deleted.

=item --agent NAME

appends NAME to the http agent string when fetching data.  This is a polite way to
tell Schedules Direct which application is being used.  It helps developers know
how many people are using their application and gives applications credit towards
free accounts.

=back

=head1 Automating configuration

Sometimes applications want to call B<tv_grab_na_dd> as a standalone application,
but automate the configure process.  The best way is to hook in to the XMLTV::Ask module,
but if that's not available, here is a solution.

=over

Step1. Application creates config file with username (and optionally password).

Step2. C<tv_grab_na_dd --dd-data lineups.xml --list-lineups>

Step3. Application adds desired lineup to config file.

Step4. C<tv_grab_na_dd --dd-data lineups.xml --reprocess --auto-config add --list-channels>

Step5. Application edits config file as needed, and deletes lineups.xml.

=back

=head1 Grabber Timing

Data Direct offers a "suggested download time" that can be retrieved with the
"--list-times" option. Its use is encouraged.

=head1 Handling Multiple Linups

tv_grab_na_dd only outputs a single lineup. If your Schedules Direct
account has multiple lineups, they are all downloaded even though only one is output.

To process multiple lineups, use separate L<--config-file|/"--config-file I<file>">.
Separate config files are also handy if you need different channel sets for a lineup
(common with MythTV). To prevent re-downloading the data on subsequent passes, the
L</--reprocess> option is recommended.

Here's an example: (the = sign is optional, but helps readability)

 tv_grab_na_dd --config-file=lineup1.dat --output=lineup1.xml --dd-data=dd.xml
 tv_grab_na_dd --config-file=lineup2.dat --output=lineup2.xml --dd-data=dd.xml --reprocess
 tv_grab_na_dd --config-file=lineup3.dat --output=lineup3.xml --dd-data=dd.xml --reprocess

Each config file specifies the desired lineup and channel list.

If you want to merge the lineups into a single file, you can use tv_cat

 tv_cat lineup1.xml lineup2.xml lineup3.xml >guide.xml

=head1 Adding icon links to listings

B<tv_grab_na_dd> checks for channel icons in a directory B<I<share>>/B<icons>.  The I<share> directory
is usually set during the install.  For windows exe users, it defaults to the location where
B<xmltv.exe> is.  B<tv_grab_na_icons> is available to download the icons.

=head1 Notes on channel lists

Channel lists can be configured both at the Schedules Direct website and through the grabber.  This is done to
allow multiple config files with different channel lists as Schedules Direct only supports a single channel map
per lineup.

Similarly, tv_grab_na_dd only supports a single channel mapping for a station. If multiple mappings
are detected, only the first one is used and you are advised to adjust your Schedules Direct lineup.

=head1 Notes on episode numbers

Three episode-num formats are supplied (when available)

=over

=item xmltv_ns

always C<..a/b> for part C<a> of C<b>. First two xmltv_ns fields always blank.

=item dd_progid

Gracenote generated C<a.b.c/d> where C<a> is a unique program id, C<b> is a unique episode id,
C<c/d> is part C<c> of C<d> similar to xmltv_ns.

=item onscreen

Distributor-designated number corresponding to an episode of a specific show. Varies by distributor.

=back

=head1 Notes on passwords

If a password is stored in the config file, the config file should be properly protected.
Instead of storing the password in the config file, it can be omitted, and will be prompted for.

=head1 Notes on lineup changes

Data Direct currently adds a channel to your lineup automatically when it is available.  When
B<tv_grab_na_dd> sees the new channel in the Schedules Direct lineup, it prints a message (and
potentially adds or ignores it based on --auto-config).

If you are sensitive to bandwidth issues, I would set B<--auto-config ignore> and periodically check
your B<--config-file> for ignored channels and remove from your Schedules Direct lineup.

=head1 Notes on previously-shown

Previous releases of tv_grab_na_dd set XMLTV's "date" field for DD "original-air-date" field.
The correct place for the data is "previously-shown->start"  The OAD is in both places temporarily
for compatibility reasons.

DD has dropped the "repeat" flag and replaced it with a "new" flag. Now we set "previously-shown

=head1 Known issues

none!
