NAME

App::DocKnot::Spin::Sitemap - Generate page navigation links for spin

SYNOPSIS

    use App::DocKnot::Spin::Sitemap;
    my $sitemap = App::DocKnot::Spin::Sitemap->new('/path/to/.sitemap');
    my @links = $sitemap->links('some/output/page.html');
    my @navbar = $sitemap->navbar('some/output/page.html');

REQUIREMENTS

Perl 5.24 or later and the List::SomeUtils and Path::Tiny modules, both of which are available from CPAN.

DESCRIPTION

App::DocKnot::Spin supports sitemap information stored in a ".sitemap" file at the top of the source directory. If this is present, it is used to add navigation information to every generated page.

App::DocKnot::Spin::Sitemap encapsulates parsing of that file and generating the HTML for inter-page links. It can also generate HTML for the entirety of the sitemap to support the "\sitemap" thread command.

The format of this file is one line per web page, with indentation showing the tree structure. Each line should be formatted as a partial URL (relative to the top of the site) starting with "/", a colon, and a page description. The partial URL should be for the generated pages, not the source files (so, for example, should use an ".html" extension). The top of the generated site should have the URL of "/" at the top of the sitemap.

If two pages at the same level aren't related and shouldn't have next and previous links to each other, they should be separated by three dashes on a line by themselves at the same indentation level.

Here's an example of a simple .sitemap file:

    /personal/: Personal Information
      /personal/contact.html: Contact Information
      ---
      /personal/projects.html: Current Projects
    /links/: Links
      /links/lit.html: Other Literature
      /links/music.html: Music
      /links/sf.html: Science Fiction and Fantasy

This defines two sub-pages of the top page, "/personal/" and "/links/". "/personal/" has two pages under it that are not part of the same set and therefore shouldn't have links to each other. "/links/" has three pages under it which are part of a set and should be linked between each other.

CLASS METHODS

new(PATH): Create a new App::DocKnot::Spin::Sitemap object for the .sitemap file specified by PATH.

INSTANCE METHODS

links(PAGE): Generate the "<link>" tags for the provided PAGE, which should be a URL relative to the top of the generated site and starting with "/". The return value is a list of lines to add to the HTML "<head>" section, or an empty list if the page was not found in the sitemap.
navbar(PAGE): Generate the navigation bar for the provided PAGE, which should be a URL relative to the top of the generated site and starting with "/". The return value is a list of HTML lines suitable for injecting into the output page.
sitemap(): Return the sitemap as a list of lines of formatted HTML, suitable for inclusion in a generated web page. This is used to implement the "\sitemap" thread command.
