NAME

XMLTV::Augment - Augment XMLTV listings files with automatic and user-defined rules.

DESCRIPTION

Augment an XMLTV xml file by applying corrections ("fixups") to programmes matching defined criteria ("rules").

Two types of rules are actioned: (i) automatic, (ii) user-defined.

Automatic rules use pre-programmed input and output to modify the input programmes. E.g. removing a "title" where it is repeated in a "sub-title" (e.g. "Horizon" / "Horizon: Star Wars"), or trying to identify and extract series/episode numbers from the programme"s title, sub-title or description.

User-defined rules use the content of a "rules" file which allows programmes matching certain user-defined criteria to be corrected/enhanced with the user data supplied (e.g. adding/changing categories for all episodes of "Horizon", or fixing misspellings in titles, etc.)

By setting appropriate options in the "config" file, the "rules" file can be automatically downloaded using XMLTV::Supplement.

EXPORTED FUNCTIONS

setEncoding

Set the assumed encoding of the rules file.

inputChannel

Store each channel found in the input programmes file for later processing by "stats".

augmentProgramme

Augment a programme using (i) pre-determined rules and (ii) user-defined rules. Which rules are processed is determined by the options set in the "config" file.

printInfo

Print the lists of actions taken and suggestions for further fixups.

end

Do any final processing before exit (e.g. close the log file if necessary).

INSTANTIATION

    new XMLTV::Augment( { ...parameters...} );

Possible parameters:
rule => filename of file containing fixup rules (if omitted then no user-defined rules will be actioned) (overrides auto-fetch Supplement if that is defined; see sample options file)
config => filename of config file to read (if omitted then no config file will be used)
encoding => assumed encoding of the rules file (default = UTF-8)
stats => whether to print the audit stats in the log (values = 0,1) (default = 1)
log => filename of output log
debug => debug level (values 0-10) (default = no debug)
note debug level > 3 is not likely to be of much use unless you are developing code

TYPICAL USAGE

 1) Create the XMLTV::Augment object
 2) Pass each channel to inputChannel()
 3) Pass each programme to augmentProgramme()
 4) Tidy up using printInfo() & end()
        #instantiate the object
        my $augment = new XMLTV::Augment(
                  "rule"       => "myrules.txt",
                  "config"     => "myconfig.txt",
                  "log"        => "augment.log",
                  );
        die "failed to create XMLTV::Augment object" if !$augment;
        for each channel... {
          # store the channel details
          $augment->inputChannel( $ch );
        }
        for each programme... {
          # augmentProgramme will now do any requested processing of the input xml
          $prog = $augment->augmentProgramme( $prog );
        }
        # log the stats
        $augment->printInfo();
        # close the log file if necessary
        $augment->end();

Note: you are responsible for reading/writing to the XMLTV .xml file; the package will not do that for you.

You can specify a wildcard with the title by using %% which represents any number of characters.

  rule: 15|cnbc.com~News~Business
  in : "Investing in India" category ""
  out: "Investing in India" category "News" + "Business"
    

You should be very careful with this one as it will add the category you specify to EVERY programme broadcast on that channel. This may not be what you always want (e.g. Teleshopping isn't really "music" even if it is on MTV!)

process_remove_numbering_from_programmes

Rule #16

Remove episode numbering from a given programme title (on an optionally-specified channel).

  If title matches the one in the prog, all programme numbering for the programme

  in : "CBeebies Bedtime Story" episode-num ".700."
  out: "CBeebies Bedtime Story" episode-num ""
