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

       Russ Allbery <rra@cpan.org>

       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.

       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.

       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.

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

       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", "pod", and "text".  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.

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

           modified
               Boolean  saying  whether  to  add  a  last modified header.  This will always be done if the file
               contains a CVS-style "$Id$" string, but otherwise will only be done if  this  option  is  set  to
               true.  The default is false.

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

       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.

       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.
