NAME¶
Pod::ParseLink - Parse an L<> formatting code in POD text
SYNOPSIS¶
use Pod::ParseLink;
my ($text, $inferred, $name, $section, $type) = parselink ($link);
DESCRIPTION¶
This module only provides a single function,
parselink(), which takes the
text of an L<> formatting code and parses it. It returns the anchor text
for the link (if any was given), the anchor text possibly inferred from the
name and section, the name or URL, the section if any, and the type of link.
The type will be one of "url", "pod", or "man",
indicating a URL, a link to a POD page, or a link to a Unix manual page.
Parsing is implemented per perlpodspec. For backward compatibility, links where
there is no section and name contains spaces, or links where the entirety of
the link (except for the anchor text if given) is enclosed in double-quotes
are interpreted as links to a section (L</section>).
The inferred anchor text is implemented per perlpodspec:
L<name> => L<name|name>
L</section> => L<"section"|/section>
L<name/section> => L<"section" in name|name/section>
The name may contain embedded E<> and Z<> formatting codes, and the
section, anchor text, and inferred anchor text may contain any formatting
codes. Any double quotes around the section are removed as part of the
parsing, as is any leading or trailing whitespace.
If the text of the L<> escape is entirely enclosed in double quotes, it's
interpreted as a link to a section for backward compatibility.
No attempt is made to resolve formatting codes. This must be done after calling
parselink() (since E<> formatting codes can be used to escape
characters that would otherwise be significant to the parser and resolving
them before parsing would result in an incorrect parse of a formatting code
like:
L<verticalE<verbar>barE<sol>slash>
which should be interpreted as a link to the "vertical|bar/slash" POD
page and not as a link to the "slash" section of the "bar"
POD page with an anchor text of "vertical". Note that not only the
anchor text will need to have formatting codes expanded, but so will the
target of the link (to deal with E<> and Z<> formatting codes),
and special handling of the section may be necessary depending on whether the
translator wants to consider markup in sections to be significant when
resolving links. See perlpodspec for more information.
