NAME

       App::DocKnot::Generate - Generate documentation from package metadata

SYNOPSIS

           use App::DocKnot::Generate;
           my $docknot
             = App::DocKnot::Generate->new({ metadata => 'docs/docknot.yaml' });
           my $readme = $docknot->generate('readme');
           my $index = $docknot->generate('thread');
           $docknot->generate_output('readme');
           $docknot->generate_output('thread', 'www/index.th')

REQUIREMENTS

       Perl 5.24 or later and the modules File::BaseDir, File::ShareDir, Kwalify, Path::Tiny, Template (part of
       Template Toolkit), and YAML::XS, all of which are available from CPAN.

DESCRIPTION

       This component of DocKnot provides a system for generating consistent human-readable software package
       documentation from metadata files, primarily JSON and files containing documentation snippets.  It takes
       as input a directory of metadata and a set of templates and generates a documentation file from the
       metadata given the template name.

       The path to the metadata directory for a package is given as an explicit argument to the
       App::DocKnot::Generate constructor.  All other data (currently templates and license information) is
       loaded via File::BaseDir and therefore uses XDG paths by default.  This means that templates and other
       global configuration are found by searching the following paths in order:

       1.  $HOME/.config/docknot

       2.  $XDG_CONFIG_DIRS/docknot (/etc/xdg/docknot by default)

       3.  Files included in the package.

       Default  templates  and  license files are included with the App::DocKnot module and are used unless more
       specific configuration files exist.

CLASS METHODS

       new(ARGS)
           Create a new App::DocKnot::Generate object.  This should be used for all  subsequent  actions.   ARGS
           should be a hash reference with one or more of the following keys:

           metadata
               The path to the directory containing metadata for a package.  Default: docs/docknot.yaml relative
               to the current directory.

           width
               The wrap width to use when generating documentation.  Default: 74.

INSTANCE METHODS

       generate(TEMPLATE)
           Load  the metadata from the path given in the constructor and generate the documentation file defined
           by TEMPLATE, which is the name  of  a  template.   The  template  itself  will  be  loaded  from  the
           App::DocKnot  configuration  path  as  described in DESCRIPTION.  Returns the generated documentation
           file as a string.

       generate_all()
           Generate all of the documentation files for a package.  This is currently defined as the "readme" and
           "readme-md" templates.  The output will be written to the  default  output  locations,  as  described
           under generate_output().

       generate_output(TEMPLATE [, OUTPUT])
           The  same  as  generate()  except  that  rather  than returning the generated documentation file as a
           string, it will be written to the file named by OUTPUT.  If that  argument  isn't  given,  a  default
           based on the TEMPLATE argument is chosen as follows:

               readme     ->  README
               readme-md  ->  README.md

           If TEMPLATE isn't one of the templates listed above, the OUTPUT argument is required.
