NAME
Pod::POM::View::Restructured - View for Pod::POM that outputs
reStructuredText
SYNOPSIS
use Pod::POM::View::Restructured;
my $view = Pod::POM::View::Restructured->new;
my $parser = Pod::POM->new;
my $pom = $parser->parse_file("$top_dir/lib/Pod/POM/View/Restructured.pm");
my $out = $pom->present($view);
DESCRIPTION
This module outputs reStructuredText that is expected to be used with
Sphinx. Verbatim sections (indented paragraphs) in the POD will be
output with syntax highlighting for Perl code by default. See "POD
commands specifically for reStructuredText" for how to change this for a
particular block.
For a list of changes in recent versions, see the documentation for
Pod::POM::View::Restructured::Changes.

METHODS
"new(\%params)"
Constructor. \%params is optional. If present, the following keys are
valid:
"callbacks"
See documentation below for "convert_file()".
"namespace"
If a namespace is declared then links to that namespace are
converted to cross references and an anchor is added for each head
tag.
"convert_file($source_file, $title, $dest_file, $callbacks)"
Converts the POD in $source_file to reStructuredText. If $dest_file is
defined, it writes the output there. If $title is defined, it is used
for the title of the document. Otherwise, an attempt is made to infer
the title from the NAME section (checks if the body looks like
"/\A\s*(\w+(?:::\w+)+)\s+-\s+/s").
Returns the output as a string.
$source_file and $dest_file can be either file names or file handles.
"convert_files($file_spec, $index_file, $index_title, $out_dir)"
Converts the files given in $file_spec to reStructuredText. If
$index_file is provided, it is the path to the index file to be created
(with a table of contents pointing to all of the files created). If
$index_title is provided, it is used as the section title for the index
file. $out_dir is the directory the generated files will be written to.
$file_spec is a reference to an array of hashes specifying attributes
for each file to be converted. The valid keys are:
"source_file"
File to convert.
"dest_file"
File to output the reStructuredText. If not provided, a file name
will be generated based on the title.
"title"
Section title for the generated reStructuredText. If not provided,
an attempt will be made to infer the title from the NAME section in
the POD, if it exists. As a last resort, a title will be generated
that looks like "section_(\d+)".
"callbacks"
A reference to a hash containing names and the corresponding
callbacks.
Currently the only valid callback is "link". It is given the text
inside a L<> section from the POD, and is expected to return a tuple
"($url, $label)". If the value returned for $label is undefined, the
value of $url is used as the label.
"no_toc"
Causes the item to not be printed to the index or return in the
"toc" field.
This method returns a hash ref with a table of contents (the "toc"
field) suitable for a reStructuredText table of contents.
E.g.,
my $conv = Pod::POM::View::Restructured->new;
my $files = [
{ source_file => "$base_dir/Restructured.pm" },
{ source_file => "$base_dir/DWIW.pm" },
{ source_file => "$base_dir/Wrapper.pm" },
];
my $rv = $conv->convert_files($files, "$dest_dir/index.rst", 'My Big Test', $dest_dir);
POD commands specifically for reStructuredText
The following sequences can be used in POD to request actions
specifically for this module.
=for pod2rst next-code-block: *lang*
This sets up the next verbatim section, i.e., the next indented
paragraph to be highlighted according to the syntax of the
programming/markup/config language *lang*. Verbatim sections are assumed
to be Perl code by default. Sphinx uses Pygments to do syntax highlighting
in these sections, so you can use any value for *lang* that Pygments
supports, e.g., Python, C, C++, Javascript, SQL, etc.
EXAMPLES
Converting a single file using "pod2rst"
pod2rst --infile=Restructured.pm --outfile=restructured.rst

TODO
code highlighting
Currently, a verbatim block (indented paragraph) gets output as a
Perl code block by default in reStructuredText. There should be an
option (e.g., in the constructor) to change the language for
highlighting purposes (for all verbatim blocks), or disable syntax
highlighting and just make it a preformatted paragraph. There is a way
to do this in POD (see "POD commands specifically for
reStructuredText"), but there should also be an option in the
constructor.
improve escaping
Text blocks are not escaped properly, so it is currently possible to
invoke a command in reStructuredText by accident.
