NAME

Org::To::Base - Base class for Org exporters

VERSION

This document describes version 0.235 of Org::To::Base (from Perl distribution Org-To-HTML), released on 2022-02-12.

SYNOPSIS

 # Not to be used directly. Use one of its subclasses, like Org::To::HTML.

DESCRIPTION

This module is a base class for Org exporters. To create an exporter, subclass from this class (as well as add Org::To::Role role) and provide an implementation for the export_*() methods. Add extra attributes for export options as necessary (for example, Org::To::HTML adds html_title, css_url, and so on).

ATTRIBUTES

include_tags

Arrayref. Works like Org's 'org-export-select-tags' variable. If the whole document doesn't have any of these tags, then the whole document will be exported. Otherwise, trees that do not carry one of these tags will be excluded. If a selected tree is a subtree, the heading hierarchy above it will also be selected for export, but not the text below those headings.

exclude_tags

Arrayref. If the whole document doesn't have any of these tags, then the whole document will be exported. Otherwise, trees that do not carry one of these tags will be excluded. If a selected tree is a subtree, the heading hierarchy above it will also be selected for export, but not the text below those headings.

exclude_tags is evaluated after "include_tags".

source_file

String. Optional. Can be set for informational purposes, e.g. will be used as default title when document does not set C>#+TITLE>.

METHODS

$exp->export($doc) => STR

Export Org.

$exp->export_elements(@elems) => STR

Export Org element objects and with the children, recursively. Will call various export_*() methods according to element class. Should return a string which is the exported document.

Several hooks are recognized and will be invoked if defined:

  • before_export_element

    Will be called before calling each export_*(). Will be passed hash argument %hash containing these keys: hook (hook name, in this case before_export_element), elem (the element object).

  • after_export_element

    Will be called after calling each export_*(). Will be passed hash argument %hash containing these keys: hook (hook name, in this case after_export_element), elem (the element object).

CONTRIBUTING

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

 % prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required beyond that are considered a bug and can be reported to me.
