 podchecker - check pod documents for syntax errors


NAME

Pod::Checker, podchecker() - check pod documents for syntax errors


SYNOPSIS

  use Pod::Checker;
  $syntax_okay = podchecker($filepath, $outputpath, %options);
  my $checker = new Pod::Checker %options;
  $checker->parse_from_file($filepath, \*STDERR);


OPTIONS/ARGUMENTS

$filepath is the input POD to read and $outputpath is where to write POD syntax error messages. Either argument may be a scalar indicating a file-path, or else a reference to an open filehandle. If unspecified, the input-file it defaults to \*STDIN, and the output-file defaults to \*STDERR.

podchecker()

This function can take a hash of options:

-warnings => val
Turn warnings on/off. val is usually 1 for on, but higher values trigger additional warnings. See Warnings.


DESCRIPTION

podchecker will perform syntax checking of Perl5 POD format documentation.

NOTE THAT THIS MODULE IS CURRENTLY IN THE BETA STAGE!

It is hoped that curious/ambitious user will help flesh out and add the additional features they wish to see in Pod::Checker and podchecker and verify that the checks are consistent with the perlpod manpage.

The following checks are currently preformed:


DIAGNOSTICS

Errors

Warnings

These may not necessarily cause trouble, but indicate mediocre style.

Hyperlinks

There are some warnings wrt. malformed hyperlinks.


RETURN VALUE

podchecker returns the number of POD syntax errors found or -1 if there were no POD commands at all found in the file.


EXAMPLES

[T.B.D.]


INTERFACE

While checking, this module collects document properties, e.g. the nodes for hyperlinks (=headX, =item) and index entries (X<>). POD translators can use this feature to syntax-check and get the nodes in a first pass before actually starting to convert. This is expensive in terms of execution time, but allows for very robust conversions.

Pod::Checker->new( %options )
Return a reference to a new Pod::Checker object that inherits from Pod::Parser and is used for calling the required methods later. The following options are recognized:

-warnings => num Print warnings if num is true. The higher the value of num, the more warnings are printed. Currently there are only levels 1 and 2.

-quiet => num If num is true, do not print any errors/warnings. This is useful when Pod::Checker is used to munge POD code into plain text from within POD formatters.

$checker->poderror( @args )
$checker->poderror( {%opts}, @args )
Internal method for printing errors and warnings. If no options are given, simply prints ``@_''. The following options are recognized and used to form the output:
  -msg

A message to print prior to @args.

  -line

The line number the error occurred in.

  -file

The file (name) the error occurred in.

  -severity

The error level, should be 'WARNING' or 'ERROR'.

$checker->num_errors()
Set (if argument specified) and retrieve the number of errors found.

$checker->name()
Set (if argument specified) and retrieve the canonical name of POD as found in the =head1 NAME section.

$checker->node()
Add (if argument specified) and retrieve the nodes (as defined by =headX and =item) of the current POD. The nodes are returned in the order of their occurence. They consist of plain text, each piece of whitespace is collapsed to a single blank.

$checker->idx()
Add (if argument specified) and retrieve the index entries (as defined by X<>) of the current POD. They consist of plain text, each piece of whitespace is collapsed to a single blank.

$checker->hyperlink()
Add (if argument specified) and retrieve the hyperlinks (as defined by L<>) of the current POD. They consist of an 2-item array: line number and Pod::Hyperlink object.
