NAME

Top

Pod::Simple::Wiki::Template - A class for creating Pod to Template wiki filters.

SYNOPSIS

Top

This module isn't used directly. Instead it is called via Pod::Simple::Wiki:

    #!/usr/bin/perl -w

    use strict;
    use Pod::Simple::Wiki;




    my $parser = Pod::Simple::Wiki->new('template');

    ...




Convert Pod to a Template wiki format using the installed pod2wiki utility:

    pod2wiki --style template file.pod > file.wiki




DESCRIPTION

Top

This module is used as a boiler plate or example of how to create a new Pod::Simple::Wiki:: module. See the Portme section below.

The Pod::Simple::Wiki::Template module is used for converting Pod text to Wiki text.

Pod (Plain Old Documentation) is a simple markup language used for writing Perl documentation.

For an introduction to Template see: http://www.portme.org

This module isn't generally invoked directly. Instead it is called via Pod::Simple::Wiki. See the Pod::Simple::Wiki and pod2wiki documentation for more information.

PORTME

Top

This module is used as a boiler plate or example of how to create a new Pod::Simple::Wiki:: module.

If you are thinking of creating a new Pod::Simple::Wiki:: you should use this module as a basis.

Portme. Any comments in the code or documentation that begin with or contain the word portme are intended for the porter, the person who is creating the new module. You should read all of the portme comments and eventully delete them when the module is finished.

The following are some suggested steps in porting the module. For the sake of example say we wish to convert Pod to a format called portmewiki. Also for the sake of this example we will assume that you know how to install and work on a module or work on it in a local source tree using -I./lib or -Mblib.

Portme Step 1

Fork, clone or download the latest version of Pod::Simple::Wiki from the github repository: http://github.com/jmcnamara/pod-simple-wiki/

Copy the /lib/Pod/Simple/Wiki/Template.pm to a new module /lib/Pod/Simple/Wiki/Portmewiki.pm.

The module name should have the first letter capitalised and all others lowercase, i.e, the same as returned by ucfirst().

Portme Step 2

Edit the module and replace all instances of Template with Portmewiki (case sensitive).

Then replace all instances of template with portmewiki (case sensitive).

Portme Step 3

The module should now work and can now be called as follows:

    use Pod::Simple::Wiki;

    my $parser = Pod::Simple::Wiki->new('portmewiki');

The default output format, in this configuration is Kwiki.

Portme Step 4

Write some tests.

Copy the tests in the /t directory for one of formats that is similar to the format that you are porting.

Portme Step 5

Modify the source of Portmewiki.pm until all the tests pass and you are happy with the output format.

Start by modifying the tags and then move on to the other methods.

If you encounter problems then you can turn on internal debugging:

    my $parser = Pod::Simple::Wiki->new('portmewiki');
    $parser->_debug(1);

    Or for more debug information that you can deal with:

    # At the start of your program and before anything else:
    use Pod::Simple::Debug (5);

    ...

    $parser->_debug(0);

If you find yourself with a difficult porting issue then you may also wish to read Pod::Simple::Methody and Pod::Simple::Subclassing.

Try to maintain the code style of this module. See the source for more information.

Portme Step 6

Remove or replace all portme comments.

Portme Step 7

Send me a git pull request or the tarred directory with libs and tests and I'll release it to CPAN.

METHODS

Top

Pod::Simple::Wiki::Template inherits all of the methods of Pod::Simple and Pod::Simple::Wiki. See Pod::Simple and Pod::Simple::Wiki for more details.

Template Specific information

Top

Portme: Add some information specific to the Template format or this module here. If required.

SEE ALSO

Top

This module also installs a pod2wiki command line utility. See pod2wiki --help for details.
