Pod::Html::Util

helper functions for Pod-Html

SUBROUTINES

Note: While these functions are importable on request from Pod::Html::Util, they are specifically intended for use within (a) the Pod-Html distribution (modules and test programs) shipped as part of the Perl 5 core and (b) other parts of the core such as the installhtml program. These functions may be modified or relocated within the core distribution – or removed entirely therefrom – as the core’s needs evolve. Hence, you should not rely on these functions in situations other than those just described.

process_command_line()

Process command-line switches (options). Returns a reference to a hash. Will provide usage message if --help switch is present or if parameters are invalid.

Calling this subroutine may modify @ARGV.

usage()

Display customary Pod::Html usage information on STDERR.

unixify()

Ensure that Pod::Html’s internals and tests handle paths consistently across Unix, Windows and VMS.

relativize_url()

Convert an absolute URL to one relative to a base URL. Assumes both end in a filename.

html_escape()

Make text safe for HTML.

htmlify()

htmlify($heading);

Converts a pod section specification to a suitable section specification for HTML. Note that we keep spaces and special characters except ", ? (Netscape problem) and the hyphen (writer’s problem…).

anchorify()

anchorify(@heading);

Similar to htmlify(), but turns non-alphanumerics into underscores. Note that anchorify() is not exported by default.

trim_leading_whitespace()

Remove any level of indentation (spaces or tabs) from each code block consistently. Adapted from: https://metacpan.org/source/HAARG/MetaCPAN-Pod-XHTML-0.002001/lib/Pod/Simple/Role/StripVerbatimIndent.pm
