ox-pandoc

This is another exporter that translates Org-mode file to various other formats via Pandoc.

Description

You can convert Org-mode file to various formats with simple commands. Following table shows the supported fromats.

Requirements

You need Emacs 24.2, org-mode 8.2, and Pandoc 2.0 (or later versions). Pandoc-Citeproc 0.3 (or later) may also be needed if you use bibliography features.

Note that Org-mode equipped with Emacs 24.3 is version 7.9 and can not be used with this tool. It is recommended to install Pandoc via Cabal, or the installer directly downloaded from official web sites, as other package managers (such as Anaconda) sometimes install old versions of Pandoc.

Installation

You can install this tool with MELPA. For example,

(setq package-archives
      '(("gnu" . "http://elpa.gnu.org/packages/")
        ("melpa" . "http://melpa.milkbox.net/packages/")))

M-x package-install ⏎
ox-pandoc ⏎

Running the Commands

For example, to convert org-mode file to ‘html5’ format, you may run the following commands.

org-pandoc-export-as-html5Exports to the HTML5 text as a buffer. org-pandoc-export-to-html5Exports to the HTML5 text file. org-pandoc-export-to-html5-and-openExports and open HTML5 file.

Customizing Shortcuts

As pandoc supports many number of formats, initial org-export-dispatch shortcut menu does not show full of its supported formats. You can customize org-pandoc-menu-entry variable (and probably restart Emacs) to change its default menu entries.

If you want delayed loading of `ox-pandoc’ when org-pandoc-menu-entry is customized, please consider the following settings in your init file.

(with-eval-after-load 'ox
  (require 'ox-pandoc))

org-pandoc

This file is inspired by org-pandoc, but entirely re-written. This tool prepares various export commands for all formats supported by pandoc.

Temporary Files

This file creates and removes “XXXX.tmpZZZZ.org” and “XXXX.tmpZZZZ.css” (if necessary) temprary files in working directory. (ZZZZ is random string.)

Obsolete In-File Options

Following options are supported in previous version of ox-pandoc. They are no longer supported.

EPUB_METADATA:obsolete. Use epub-metadata in PANDOC_OPTIONS: instead. EPUB_STYLESHEET:obsolete. Use epub-stylesheet in PANDOC_OPTIONS: instead.

Citation

Currently, Pandoc citation key is expressed as @key, rather than {\cite key} . You may need some text converter if you want to use Pandoc citation styles in org document.
