DESCRIPTIONOutput TV listings in XMLTV format for many channels available in the United Kingdom and Republic of Ireland. Source data comes from machine-readable files made available from the Radio Times website.
USAGEFirst run tv_grab_uk_rt --configure to choose which channels you want to receive listings for. Then run tv_grab_uk_rt (with optional arguments) to get around 14 days of listings for your configured channels.
OPTIONS--help Print a help message and exit.
--version Show the versions of the XMLTV libraries, the grabber and of key modules used for processing listings.
--capabilities Show which capabilities the grabber supports. For more information, see <http://wiki.xmltv.org/index.php/XmltvCapabilities>
--description Show a brief description of the grabber.
--config-file FILE Specify the name of the configuration file to use. If not specified, a default of ~/.xmltv/tv_grab_uk_rt.conf is used. This is also the default file written by --configure and read when grabbing.
--output FILE When grabbing, write output to FILE rather than to standard output.
--days N When grabbing, grab N days of data instead of all available. Supported values are 1-15.
--offset N Start grabbing at today + N days. Supported values are 0-14.
Note that due to the format of the source data, tv_grab_uk_rt always downloads data for all available days and then filters for days specified with --days and --offset. Specifying --days and/or --offset in order to speed up downloads or reduce data transfer will therefore have no effect.
--quiet Suppress all progress messages normally written to standard error.
--debug Provide detailed progress messages to standard error. Due to the volume of debug information produced, it is not advised to use this option during normal grabber use.
--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.
--configure Prompt for which channels/lineup to download listings for, where to store the cache directory for retrieved listings, what character encoding to use for output, and whether to enable programme title and bad character fixups.
--list-channels Outputs an XML document containing all channels available to the grabber.
--list-lineups Outputs an XML document containing all channel lineups available to the grabber.
--get-lineup Outputs an XML document containing the configured channel lineup.

CHANNEL LINEUPSA channel lineup is a list of TV and radio channels that are available in a particular location on a particular TV platform (e.g. Freeview).
Whilst configurations containing individual ``channel=...'' entries are still supported, the grabber allows a user to select their location and TV platform at configuration time and have their channel lineup generated dynamically at runtime. This means that if a new channel launches or a channel ceases broadcasting, an update to the relevant lineup (stored on the XMLTV server) will result in listings containing such channel changes without any reconfiguration by the user.
CHARACTER ENCODINGDuring configuration, the software asks the user to choose the character encoding to be used for output. Currently supported encodings are UTF-8 and ISO-8859-1.
TITLE PROCESSINGOver time, listings may contain inconsistent programme details, such as the programme title combined with episode details for some showings of a programme, but separate for others; or the episode title being given as the programme title, and the programme title given as the episode title. Some programme titles may also change slightly over time, or across channels.
Enabling title processing during configuration enables this software to process programme titles against a list of flagged titles. The software will correct such programme titles, which in turn should result in better performance of PVR software which rely on consistent programme data. Please be aware that enabling title processing will result in the grabber taking slightly longer to complete its operation due to the extra processing overhead.
N.B. Please note that title updates can clearly alter programme titles near to transmission time, and it is therefore quite possible for PVR schedules to fail if they have been configured using an old title. Whilst care is taken to ensure title updates are made as far ahead of transmission as possible, be aware that last minute updates can be made.
MIS-ENCODED UTF-8 SOURCE DATAPrior to the transition of the XMLTV service to metabroadcast.com in December 2011, there was an ongoing issue with source data containing mis-encoded UTF-8 characters. Since the transition, the source data should be UTF-8 safe and automatic processing of the data may not be required. A configuration option is provided to permit detection and correction of such character encoding errors and users are recommended to enable this option during configuration.
PERFORMANCEImprovements to date and time handling in the grabber have increased performance 6-7X. Grabbing 14 days of listings with utf-8 and title fixups enabled should take about 2 seconds per configured channel on a typical machine.
ERROR HANDLINGtv_grab_uk_rt will only terminate early if it is impossible to continue with grabbing data. This can be due to a lack of channel configuration data, a bad/missing configuration file, or filesystem permission problems. Running the grabber in non-quiet mode should report why the grabber failed.
Non-fatal errors are reported during a grabber run, and can result in listings for a channel being skipped either in part, or entirely. Progress messages will state why data is missing when it is possible to do so. A non-zero exit status will normally be given when the grabber has encountered problems during listings retrieval.
ENVIRONMENT VARIABLESThe environment variable HOME can be set to change where the configuration file is stored. All configuration is stored in $HOME/.xmltv/ by default. On Windows it might be necessary to set HOME to a pathname containing no spaces.
The environment variable XMLTV_SUPPLEMENT can be set to change where the supplemental XMLTV files are retrieved from. By default, the file is retrieved from the XMLTV supplement server. See XMLTV::Supplement for more information.
If you want the grabber to use customised local copies of the supplemental files, you should set XMLTV_SUPPLEMENT to the path of the directory containing a tv_grab_uk_rt/ directory containing the supplement files. For example, if your local supplement files are stored in /usr/local/share/xmltv/tv_grab_uk_rt/ you should `export XMLTV_SUPPLEMENT=``/usr/local/share/xmltv/''` before running the grabber.
RADIO LISTINGSIronically, the Radio Times feed does not offer listings for radio. They have been asked about the possibility of adding radio listings, but stated that this would require significant development effort. It has not been ruled out entirely, but is unlikely to be added soon.
Users who would like to obtain BBC radio listings in XMLTV format are advised to investigate a new grabber that obtains listings from the BBC Backstage service. See <http://wiki.xmltv.org/index.php/BBC_Backstage> for more information.
MAILING LISTYou can subscribe to and read the XMLTV users mailing list by visiting <http://lists.sourceforge.net/lists/listinfo/xmltv-users>. This is a source of help and advice for new users. A searchable archive of the list is available at <http://news.gmane.org/gmane.comp.tv.xmltv.general>.
BUGSIf you encounter a reproducible bug, please report it on the XMLTV bug tracker at <http://sourceforge.net/tracker/?group_id=39046&atid=424135>, making sure you assign the bug to the tv_grab_uk_rt category. Please check that the bug has not already been reported.
The source data on the Radio Times website is generated daily before 0600. Occasionally the source data may not get recreated, leaving the source files for some (or all) channels empty. Users are encouraged to wait at least 1 day before reporting an issue with missing listings, as they frequently reappear in the next update or later the same day. If listings continue to be missing from the Radio Times website, please report the fact on the XMLTV users mailing list.
There have been several occasions in the past when the Radio Times channel index has been missing from the Radio Times website. This file is essential to being able to run the grabber, as it contains the list of channels having available listings data. If this file is missing or empty, and there is no locally-cached copy of the file, it will not be possible to run the grabber. The file usually regenerates automatically over the course of the next day, at which point it will be possible to run the grabber successfully.
There are no other reported ongoing issues.
