AsciiDocBookFormatter(3pm)

NAME
Lire::ReportParser::AsciiDocBookFormatter - Lire::ReportParser subclass which formats description.

SYNOPSIS
To format DocBook:

    use Lire::ReportParser::AsciiDocBookFormatter qw/dbk2txt/;

    my $txt = dbk2txt( "<para>Test</para>" );

In XML Report processors :

    package MyParser;

    use base qw/ Lire::ReportParser::AsciiDocBookFormatter Lire::ReportParser /;

    sub new {
        my $self = shift->SUPER::new( @_ );

        $self->init_docbook_formatter( @_ );

        return $self;
    }

    sub handle_description {
        my ( $self, $desc ) = @_;

        print $desc;

        return;
    }

DESCRIPTION
This package implements methods that can handle the content of "description" elements and it can be used by a subclass of Lire::ReportParser. Client only have to inherit from this module so that a handle_description() method is available to process the text formatted DocBook description.

This module also provide a convenient dbk2txt() function which can be used to format a string containing DocBook elements into an ASCII equivalent.

USING Lire::ReportParser::AsciiDocBookFormatter
Lire::ReportParser processors that would like to work with text version of the description should inherit from Lire::ReportParser::AsciiDocBookFormatter in addition to Lire::ReportParser. If they override the description_start(), description_end()methods, they must link to their parents' version using "SUPER::".

Additionnally, they should merge the value elements_spec() in their elements_spec() implementation.

The Lire::ReportParser::AsciiDocBookFormatter should be listed before Lire::ReportParser in the @ISA. The AsciiDocBookFormatter doesn't inherit directly from Lire::ReportParser so that it can be used in multiple inheritance scenario.

The subclass should call the init_docbook_formatter() method from their constructor method to initialize the DocBookFormatter module.

  init_docbook_formatter( %params )
The initializer recognizes some parameters that can be used to control the behavior of the DocBook handling:

columns
    The number of columns in which the DocBook text should be formatted. Defaults to 72.

  dbk_start_processing()
Initializes the parser's structure for formatting DocBook XML as ASCII. This is used from the description_start implementation.

  dbk_end_processing()
Cleans the parser structure. This is used from the description_end() implementation.

  handle_description( $description )
This method is invoked after the closing tag of the "description" element is encountered. The $description contains the description formatted in plain text.

FORMATTING DocBook STRINGS
If you have DocBook content in a string, like you can obtain from some of the Report Specifications object, you can format it in plain text using the dbx2txt() function.

  dbk2txt( $docbook_str, [$columns] )
Returns a plain text version of the DocBook XML fragment $docbook_str. The "columns" parameter sets the number of columns in which the DocBook text should be formatted.

This method will die() in case of error.
