Pod::Readme - Convert POD to README file
use Pod::Readme; my $parser = Pod::Readme->new(); # Read POD from STDIN and write to STDOUT $parser->parse_from_filehandle; # Read POD from Module.pm and write to README $parser->parse_from_file('Module.pm', 'README');
This module is a subclass of Pod::PlainText which provides additional POD markup for generating README files.
Why should one bother with this? One can simply use
pod2text Module.pm > README
A problem with doing that is that the default pod2text converter will add text to links, so that "L<Module>" is translated to "the Module manpage".
Another problem is that the README includes the entirety of the module documentation! Most people browsing the README file do not need all of this information.
Likewise, including installation and requirement information in the module documentation is not necessary either, since the module is already installed.
This module allows authors to mark portions of the POD to be included only in, or to be excluded from the README file. It also allows you to include portions of another file (such as a separate ChangeLog).
Special POD markup options are described below:
=begin readme =head1 README ONLY This section will only show up in the README file. =end readme
Delineates a POD section that is only available in README file. If you prefer to include plain text instead, add the
=begin readme text README ONLY (PLAINTEXT) This section will only show up in the README file. =end readme
Note that placing a colon before the section to indicate that it is POD (e.g.
begin :readme) is not supported in this version.
=for readme stop
All POD that follows will not be included in the README, until a
continue command occurs:
=for readme continue
=for readme include file=filename type=type start=Regexp stop=Regexp =for readme include file=Changes start=^0.09 stop=^0.081 type=text
Includes a plaintext file named filename, starting with the line that contains the start
Regexp and ending at the line that begins with the stop
Regexp. (The start and stop Regexps are optional: one or both may be omitted.)
Type may be
pod. If omitted,
pod will be assumed.
Quotes may be used when the filename or marks contains spaces:
=for readme include file="another file.pod"
One can also using maintain multiple file types (such as including TODO, or COPYING) by using a modified constructor:
$parser = Pod::Readme->new( readme_type => "copying" );
In the above "Markup" commands replace "readme" with the tag specified instead (such as "copying"):
As of version 0.03 you can specify multiple sections by separating them with a comma:
There is also no standard list of type names. Some names might be recognized by other POD processors (such as "testing" or "html"). Pod::Readme will reject the following "known" type names when they are specified in the constructor:
testing html xhtml xml docbook rtf man nroff dsr rno latex tex code
You can also use a "debug" mode to diagnose any problems, such as mistyped format names:
$parser = Pod::Readme->new( debug => 1 );
Warnings will be issued for any ignored formatting commands.
For an example, see the Readme.pm file in this distribution.
