oracular (3) App::DocKnot::Spin::Pointer.3pm.gz
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", "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.
