# Pod::Html::Util - helper functions for Pod-Html - perldoc - [phpMan]

## NAME
    [Pod::Html::Util](https://www.chedong.com/phpMan.php/perldoc/Pod%3A%3AHtml%3A%3AUtil/markdown) - helper functions for Pod-Html

## SUBROUTINES
    Note: While these functions are importable on request from [Pod::Html::Util](https://www.chedong.com/phpMan.php/perldoc/Pod%3A%3AHtml%3A%3AUtil/markdown), 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](https://www.chedong.com/phpMan.php/perldoc/Pod%3A%3AHtml/markdown) usage information on STDERR.

  unixify()
    Ensure that [Pod::Html](https://www.chedong.com/phpMan.php/perldoc/Pod%3A%3AHtml/markdown)'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:
