NAME

Locale::Maketext::Extract::Plugin::Base - Base module for format parser plugins

SYNOPSIS

     package My::Parser::Plugin;
     use base qw(Locale::Maketext::Extract::Plugin::Base);
 
     sub file_types {
         return [qw( ext ext2 )]
     }
 
     sub extract {
         my $self = shift;
         my $filename = shift;
         local $_ = shift;
 
         my $line = 1;
 
         while (my $found = $self->routine_to_extract_strings) {
             $self->add_entry($str,[$filename,$line,$vars])
         }
 
         return;
     }
 
 

DESCRIPTION

All format parser plugins in Locale::Maketext::Extract inherit from Locale::Maketext::Extract::Plugin::Base.

If you want to write your own custom parser plugin, you will need to inherit from this module, and provide "file_types()" and "extract()" methods, as shown above.

METHODS

new()

     $plugin = My::Parser->new(
         @file_types         # Optionally specify a list of recognised file types
     )
 
 

add_entry()

     $plugin->add_entry($str,$line,$vars)
 
 

entries()

     $entries = $plugin->entries;
 
 

clear()

     $plugin->clear
 
 

Clears all stored entries.

file_types()

     @default_file_types = $plugin->file_types
 
 

Returns a list of recognised file types that your module knows how to parse.

Each file type can be one of:

*

A plain string

    'pl'  => base filename is matched against qr/\.pl$/
    '*'   => all files are accepted
 
 

*

A regex

    qr/\.tt2?\./ => base filename is matched against this regex
 
 

*

A codref

     sub {}  => this codref is called as $coderef->($base_filename,$path_to_file)
                It should return true or false
 
 

extract()

     $plugin->extract($filecontents);
 
 

extract() is the method that will be called to process the contents of the current file.

When it finds a string that should be extracted, it should call

    $self->add_entry($string,$line,$vars])
 
 

where $vars refers to any arguments that are being passed to the localise function. For instance:

    l("You found [quant,_1,file,files]",files_found)
 
      string: "You found [quant,_1,file,files]"
      vars  : (files_found)
 
 

IMPORTANT: a single plugin instance is used for all files, so if you plan on storing state information in the $plugin object, this should be cleared out at the beginning of "extract()"

known_file_type()

     if ($plugin->known_file_type($filename_with_path)) {
         ....
     }
 
 

Determines whether the current file should be handled by this parser, based either on the list of file_types specified when this object was created, or the default file_types specified in the module.
