NAME

       App::DocKnot::Spin::Pointer - Generate HTML from a pointer to an external file

SYNOPSIS

           use App::DocKnot::Spin::Pointer;
           use App::DocKnot::Spin::Sitemap;
           use Path::Tiny qw(path);

           my $sitemap_path = path('/input/.sitemap');
           my $sitemap = App::DocKnot::Spin::Sitemap->new($sitemap_path);
           my $pointer = App::DocKnot::Spin::Pointer->new({
               output  => path('/output'),
               sitemap => $sitemap,
           });
           my $input = path('/input/file.spin');
           my $output = path('/output/file.html');
           $pointer->spin_pointer($input, $output);

REQUIREMENTS

       Perl 5.24 or later and the modules File::ShareDir, Kwalify, List::SomeUtils, Path::Tiny,
       Pod::Thread, and YAML::XS, all of which are available from CPAN.

DESCRIPTION

       The tree of input files for App::DocKnot::Spin may contain pointers to external files in
       various formats.  These files are in YAML format and end in ".spin".  This module
       processes those files and converts them to HTML and, if so configured, adds the links to
       integrate the page with the rest of the site.

       For the details of the pointer file format, see "POINTER FILES" below.

CLASS METHODS

       new(ARGS)
           Create a new App::DocKnot::Spin::Pointer object.  A single converter object can be
           used repeatedly to convert pointers in a tree of files.  ARGS should be a hash
           reference with one or more of the following keys, all of which are optional:

           output
               The path to the root of the output tree when converting a tree of files.  This
               will be used to calculate relative path names for generating inter-page links
               using the provided "sitemap" argument.  If "sitemap" is given, this option should
               also always be given.

           sitemap
               An App::DocKnot::Spin::Sitemap object.  This will be used to create inter-page
               links.  For inter-page links, the "output" argument must also be provided.

           style-url
               The base URL for style sheets.  A style sheet specified in a pointer file will be
               considered to be relative to this URL and this URL will be prepended to it.  If
               this option is not given, the name of the style sheet will be used verbatim as its
               URL, except with ".css" appended.

           thread
               An App::DocKnot::Spin::Thread object, used for converting POD into HTML.  It
               should be configured with the same App::DocKnot::Spin::Sitemap object as the
               "sitemap" argument.

INSTANCE METHODS

       is_out_of_date(POINTER, OUTPUT)
           Returns true if OUTPUT is missing or if it was modified less recently than the
           modification time of either POINTER or the underlying file that it points to.  Both
           paths must be Path::Tiny objects.

       spin_pointer(POINTER, OUTPUT)
           Convert a single pointer file to HTML.  POINTER is the path to the pointer file, and
           OUTPUT is the path to where to write the output.  Both paths must be Path::Tiny
           objects.

POINTER FILES

       A pointer file is a YAML file ending in ".spin" that points to the source file for a
       generated HTML page and provides additional configuration for its conversion.  The valid
       keys for a pointer file are:

       format
           The format of the source file.  Supported values are "markdown" and "pod".  Required.

       path
           The path to the source file.  It may be relative, in which case it's relative to the
           pointer file.  Required.

       options
           Additional options that control the conversion to HTML.  These will be different for
           each supported format.

           "markdown" has no supported options.

           The supported options for a format of "pod" are:

           contents
               Boolean saying whether to generate a table of contents.  The default is false.

           navbar
               Boolean saying whether to generate a navigation bar at the top of the page.  The
               default is true.

       style
           The style sheet to use for the converted output.  Optional.  If not set, converted
           "markdown" output will be unstyled and converted "pod" output will use a style sheet
           named "pod".

       title
           The title of the converted page.  Optional.  If not set, the title will be taken from
           the converted file in a format-specific way.  For Markdown, the title will be the
           contents of the first top-level heading.  For POD, the title will be taken from a NAME
           section formatted according to the conventions for manual pages.
