It uses no special formatting controls or codes whatsoever, and its output is therefore suitable for nearly any device.</p> <p>As a derived class from Pod::Simple, Pod::Text supports the same methods and interfaces. See <a href="/5.20.0/Pod::Simple">Pod::Simple</a> for all the details; briefly, one creates a new parser with <code>Pod::Text->new()</code> and then normally calls parse_file().</p> <p>new() can take options, in the form of key/value pairs, that control the behavior of the parser. The currently recognized options are:</p> <dl> <dt id="alt"><a class="permalink" href="#alt">#</a>alt</dt> <dd> <p>If set to a true value, selects an alternate output format that, among other things, uses a different heading style and marks <code>=item</code> entries with a colon in the left margin. Defaults to false.</p> </dd> <dt id="code"><a class="permalink" href="#code">#</a>code</dt> <dd> <p>If set to a true value, the non-POD parts of the input file will be included in the output. Useful for viewing code documented with POD blocks with the POD rendered and the code left intact.</p> </dd> <dt id="errors"><a class="permalink" href="#errors">#</a>errors</dt> <dd> <p>How to report errors. <code>die</code> says to throw an exception on any POD formatting error. <code>stderr</code> says to report errors on standard error, but not to throw an exception. <code>pod</code> says to include a POD ERRORS section in the resulting documentation summarizing the errors. <code>none</code> ignores POD errors entirely, as much as possible.</p> <p>The default is <code>pod</code>.</p> </dd> <dt id="indent"><a class="permalink" href="#indent">#</a>indent</dt> <dd> <p>The number of spaces to indent regular text, and the default indentation for <code>=over</code> blocks. Defaults to 4.</p> </dd> <dt id="loose"><a class="permalink" href="#loose">#</a>loose</dt> <dd> <p>If set to a true value, a blank line is printed after a <code>=head1</code> heading. If set to false (the default), no blank line is printed after <code>=head1</code>, although one is still printed after <code>=head2</code>. This is the default because it's the expected formatting for manual pages; if you're formatting arbitrary text documents, setting this to true may result in more pleasing output.</p> </dd> <dt id="margin"><a class="permalink" href="#margin">#</a>margin</dt> <dd> <p>The width of the left margin in spaces. Defaults to 0. This is the margin for all text, including headings, not the amount by which regular text is indented; for the latter, see the <i>indent</i> option. To set the right margin, see the <i>width</i> option.</p> </dd> <dt id="nourls"><a class="permalink" href="#nourls">#</a>nourls</dt> <dd> <p>Normally, L<> formatting codes with a URL but anchor text are formatted to show both the anchor text and the URL. In other words:</p> <pre><code class="plaintext">L<foo|http://example.com/></code></pre> <p>is formatted as:</p> <pre><code class="plaintext">foo <http://example.com/></code></pre> <p>This option, if set to a true value, suppresses the URL when anchor text is given, so this example would be formatted as just <code>foo</code>. This can produce less cluttered output in cases where the URLs are not particularly important.</p> </dd> <dt id="quotes"><a class="permalink" href="#quotes">#</a>quotes</dt> <dd> <p>Sets the quote marks used to surround C<> text. If the value is a single character, it is used as both the left and right quote; if it is two characters, the first character is used as the left quote and the second as the right quoted; and if it is four characters, the first two are used as the left quote and the second two as the right quote.</p> <p>This may also be set to the special value <code>none</code>, in which case no quote marks are added around C<> text.</p> </dd> <dt id="sentence"><a class="permalink" href="#sentence">#</a>sentence</dt> <dd> <p>If set to a true value, Pod::Text will assume that each sentence ends in two spaces, and will try to preserve that spacing. If set to false, all consecutive whitespace in non-verbatim paragraphs is compressed into a single space.

If this option is given, the output encoding is forced to UTF-8.</p> <p>Be aware that, when using this option, the input encoding of your POD source must be properly declared unless it is US-ASCII or Latin-1. POD input without an <code>=encoding</code> command will be assumed to be in Latin-1, and if it's actually in UTF-8, the output will be double-encoded. See <a href="http://man.he.net/man1/perlpod">perlpod(1)</a> for more information on the <code>=encoding</code> command.</p> </dd> <dt id="width"><a class="permalink" href="#width">#</a>width</dt> <dd> <p>The column at which to wrap text on the right-hand side.

By default, the output is sent to <code>STDOUT</code>, but this can be changed with the output_fh() method.</p> <p>The standard Pod::Simple method parse_from_file() takes up to two arguments, the first being the input file to read POD from and the second being the file to write the formatted output to.</p> <p>You can also call parse_lines() to parse an array of lines or parse_string_document() to parse a document already in memory. As with parse_file(), parse_lines() and parse_string_document() default to sending their output to <code>STDOUT</code> unless changed with the output_fh() method.</p> <p>To put the output from any parse method into a string instead of a file handle, call the output_string() method instead of output_fh().</p> <p>See <a href="/5.20.0/Pod::Simple">Pod::Simple</a> for more specific details on the methods available to all derived parsers.</p> <h1 id="DIAGNOSTICS"><a class="permalink" href="#DIAGNOSTICS">#</a>DIAGNOSTICS</h1> <dl> <dt id="Bizarre-space-in-item"><a class="permalink" href="#Bizarre-space-in-item">#</a><a id="Bizarre"></a>Bizarre space in item</dt> <dd> </dd> <dt id="Item-called-without-tag"><a class="permalink" href="#Item-called-without-tag">#</a><a id="Item"></a>Item called without tag</dt> <dd> <p>(W) Something has gone wrong in internal <code>=item</code> processing.

The <code>utf8</code> option is therefore not supported unless Perl is built with PerlIO support.</p> <h1 id="CAVEATS"><a class="permalink" href="#CAVEATS">#</a>CAVEATS</h1> <p>If Pod::Text is given the <code>utf8</code> option, the encoding of its output file handle will be forced to UTF-8 if possible, overriding any existing encoding. This will be done even if the file handle is not created by Pod::Text and was passed in from outside. This maintains consistency regardless of PERL_UNICODE and other settings.</p> <p>If the <code>utf8</code> option is not given, the encoding of its output file handle will be forced to the detected encoding of the input POD, which preserves whatever the input text is. This ensures backward compatibility with earlier, pre-Unicode versions of this module, without large numbers of Perl warnings.</p> <p>This is not ideal, but it seems to be the best compromise. If it doesn't work for you, please let me know the details of how it broke.</p> <h1 id="NOTES"><a class="permalink" href="#NOTES">#</a>NOTES</h1> <p>This is a replacement for an earlier Pod::Text module written by Tom Christiansen. It has a revamped interface, since it now uses Pod::Simple, but an interface roughly compatible with the old Pod::Text::pod2text() function is still available. Please change to the new calling convention, though.</p> <p>The original Pod::Text contained code to do formatting via termcap sequences, although it wasn't turned on by default and it was problematic to get it to work at all. This rewrite doesn't even try to do that, but a subclass of it does.
