.SH "NAME"
XMLTV::Configure \- Configuration file handling for XMLTV grabbers
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Utility library that helps grabbers read from configuration files
and implement a configuration method that can be run from the
command-line.
.SH "EXPORTED FUNCTIONS"
.IX Header "EXPORTED FUNCTIONS"
All these functions are exported on demand.
.IP "LoadConfig" 4
.IX Item "LoadConfig"
Takes the name of the configuration file to load as a parameter.
.Sp
Returns a hashref with configuration fieldnames as keys. Note
that the values of the hash are references to an array of values.
.Sp
Example:
  {
    username => [ 'mattias' ],
    password => [ 'xxx' ],
    channel => [ 'svt1.svt.se', 'kanal5.se' ],
    no_channel => ['svt2.svt.se' ],
  }
.Sp
Note that unselected options from a selectmany are collected
in an entry named after the key with a prefix of 'no_'. See
the channel and no_channel entry in the example. They are the
result of a selectmany with id=channel.
.Sp
The configuration file must be in the format described in
the file \*(L"ConfigurationFiles.txt\*(R". If the file does not
exist or if the format is wrong, LoadConfig returns undef.
.IP "SaveConfig" 4
.IX Item "SaveConfig"
Write a configuration hash in the format returned by LoadConfig to
a file that can be loaded with LoadConfig. Takes two parameters, a reference
to a configuration hash and a filename.
.Sp
Note that a grabber should normally never have to call SaveConfig. This
is done by the Configure-method.
.IP "Configure" 4
.IX Item "Configure"
Generates a configuration file for the grabber.
.Sp
Takes three parameters: stagesub, listsub and the name of the configuration
file.
.Sp
stagesub shall be a coderef that takes a stage-name or undef
and a configuration hashref as a parameter and returns an
xml-string that describes the configuration necessary for that stage.
The xml-string shall follow the xmltv\-configuration.dtd.
.Sp
listsub shall be a coderef that takes a configuration hash as returned
by LoadConfig as the first parameter and an option hash as returned by
ParseOptions as the second parameter and returns an xml-string
containing a list of all the channels that the grabber can deliver
data for using the supplied configuration. Note that the listsub
shall not use any channel-configuration from the hashref.
