NAME

Pod::Tree::PerlMap - map names to URLs

SYNOPSIS

  $perl_map = new Pod::Tree::PerlMap;
  
  $perl_map->add_page  ($name, $file);
  $perl_map->add_func  ($func, $file);
  $perl_map->force_func(0);
  $perl_map->force_func(1);
  $perl_map->set_depth ($depth);
  
  ($base, $page, $section) = $perl_map->map($base, $page, $section);

DESCRIPTION

Pod::Tree::PerlMap maps L<> markups to URLs.

The Pod::Tree::Perl* translators make entries in the map. Pod::Tree::HTML uses the map to translate links before it emits them.

METHODS

$perl_map->add_page($name, $file)

Map $name to $file. $name is the name of a POD, as used in L<> markups. $file is the path to the HTML file that is the target of the link.

$perl_map->add_func($func, $file)

Maps $func to $file. $func is the name of a function described in perlfunc.pod. $file is the name of the HTML file where it is described.

$perl_map->force_func($state)

Controls interpretation of links of the form L<func>.

If $state is true, calls to map will interpret L<func> as L<perlfunc/func>.

If $state is false, calls to map will interpret L<func> normally.

$perl_map->set_depth($depth)

Informs $perl_map of the depth of the referring page in the HTML directory tree. $perl_map needs to know this so that it can construct relative links.

($base, $page, $section) = $perl_map->map($base, $page, $section)

Remaps a link.

$base is the base URL for the HTML page, if any. $page is the page given in an L<> markup. $section is the section given in the L<> markup, if any.

map returns a new $base, $page, and $section that can be used to construct a link to the HTML page.
