NAME

6       Pod::ParseLink - Parse an L<> formatting code in POD text
7

SYNOPSIS

9           use Pod::ParseLink;
10           my $link = get_link();
11           my ($text, $inferred, $name, $section, $type) = parselink($link);
12

DESCRIPTION

14       This module only provides a single function, parselink(), which takes
15       the text of an L<> formatting code and parses it.  It returns the
16       anchor text for the link (if any was given), the anchor text possibly
17       inferred from the name and section, the name or URL, the section if
18       any, and the type of link.  The type will be one of "url", "pod", or
19       "man", indicating a URL, a link to a POD page, or a link to a Unix
20       manual page.
21
22       Parsing is implemented per perlpodspec.  For backward compatibility,
23       links where there is no section and name contains spaces, or links
24       where the entirety of the link (except for the anchor text if given) is
25       enclosed in double-quotes are interpreted as links to a section
26       (L</section>).
27
28       The inferred anchor text is implemented per perlpodspec:
29
30           L<name>         =>  L<name|name>
31           L</section>     =>  L<"section"|/section>
32           L<name/section> =>  L<"section" in name|name/section>
33
34       The name may contain embedded E<> and Z<> formatting codes, and the
35       section, anchor text, and inferred anchor text may contain any
36       formatting codes.  Any double quotes around the section are removed as
37       part of the parsing, as is any leading or trailing whitespace.
38
39       If the text of the L<> escape is entirely enclosed in double quotes,
40       it's interpreted as a link to a section for backward compatibility.
41
42       No attempt is made to resolve formatting codes.  This must be done
43       after calling parselink() (since E<> formatting codes can be used to
44       escape characters that would otherwise be significant to the parser and
45       resolving them before parsing would result in an incorrect parse of a
46       formatting code like:
47
48           L<verticalE<verbar>barE<sol>slash>
49
50       which should be interpreted as a link to the "vertical|bar/slash" POD
51       page and not as a link to the "slash" section of the "bar" POD page
52       with an anchor text of "vertical".  Note that not only the anchor text
53       will need to have formatting codes expanded, but so will the target of
54       the link (to deal with E<> and Z<> formatting codes), and special
55       handling of the section may be necessary depending on whether the
56       translator wants to consider markup in sections to be significant when
57       resolving links.  See perlpodspec for more information.
