ox-hugo is an Org exporter backend that exports Org to Hugo-compatible Markdown (Blackfriday) and also generates the front-matter (in TOML or YAML format).

The ox-hugo backend extends from a parent backend ox-blackfriday.el. The latter is the one that primarily does the Blackfriday-friendly Markdown content generation. The main job of ox-hugo is to generate the front-matter for each exported content file, and then append that generated Markdown to it.

There are, though, few functions that ox-hugo.el overrides over those by ox-blackfriday.el.

Screenshots #

Before you read further, you can see below how ox-hugo translates Org to Markdown (Org on the left; exported Markdown with Hugo front-matter on the right).

One post per Org subtree (preferred) #

Editorial #

The preferred way to organize the posts is as Org subtrees (also the main reason to write this package, as nothing like that was out there) as it makes the meta-data management for Hugo front-matter pretty effortless.

If you are a one Org-file per post type of a person, that flow works too! Just note that in this flow many of those #+hugo_ properties need to be managed manually.. just as one would manage the front-matter in Markdown files — See the Org versions in the above screenshots for comparison.

Demo #

Org source → ox-hugo Exported Markdown → https://ox-hugo.scripter.co/test/

The test site uses a minimal theme written just for debug purposes (not extra aesthetics). The test site is designed to verify if all the content translates from Org to Markdown as expected.

See Hugo Themes for examples of really good site prettification and presentation styles.

Installation #

This package requires at least GNU Emacs 26.3 and Org Mode 9.0. It is available on Melpa (https://melpa.org/#/ox-hugo), and it’s recommended to install this package from Melpa (​not Melpa Stable).

You will need to require the package after installing it to get the ox-hugo export options in the Org Export Dispatcher menu (the one you see when you hit C-c C-e to initiate any export).

You can do that by adding the below to your config:

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

Use Package #

If you use use-package, you can do the below instead:

(use-package ox-hugo
  :ensure t   ;Auto-install the package from Melpa
  :pin melpa  ;`package-archives' should already have ("melpa" . "https://melpa.org/packages/")
  :after ox)

Spacemacs #

Spacemacs users can use ox-hugo by setting the variable org-enable-hugo-support.

(setq-default dotspacemacs-configuration-layers
              '((org :variables
                  org-enable-hugo-support t)))

This was verified to work on Spacemacs develop branch (ref).

Usage #

Jump to the Quick Start section to quickly try out ox-hugo with Hugo.

Before you export #

Before you export check that these properties are set as you need:

HUGO_BASE_DIR

Root directory of the source for the Hugo site. If this is set to ~/hugo/, the exported Markdown files will be saved to ~/hugo/content/<HUGO_SECTION>/ directory¹. By default, the Markdown files reside in a hierarchy under the content/ directory in the site root directory (ref).

If you try to export without setting this property, you will get this error:

user-error: It is mandatory to set the HUGO_BASE_DIR property
            or the `org-hugo-base-dir' local variable

This property can be set by one of two ways:

1. Setting the #+hugo_base_dir: keyword in the Org file.
2. Setting the org-hugo-base-dir variable in a .dir-locals.el or File Local Variables.

HUGO_SECTION

The default Hugo section name for all the posts. See here for more information on Hugo sections. It is common for this property to be set to posts or blog. The default value is set using org-hugo-default-section-directory. See Hugo Section for details.

Important: If you choose to export an Org subtree as a post, you need to set the EXPORT_FILE_NAME subtree property. That property is used by this package to figure out where the current post starts. For that reason, a subtree with EXPORT_FILE_NAME property cannot nest another subtree with that property. If you can analogize with the branch/leaf data structure terminlogy, then the subtrees with EXPORT_FILE_NAME property need to be leaf nodes.

Export bindings #

The common ox-hugo export bindings are:

For both one-post-per-subtree and one-post-per-file flows #

C-c C-e H H

Export “What I Mean”. This is same as calling the org-hugo-export-wim-to-md function interactively or via (org-hugo-export-wim-to-md) in Emacs Lisp.

• If point is in a valid Hugo post subtree, export that subtree to a Hugo post in Markdown.

  A valid Hugo post subtree is an Org subtree that has the EXPORT_FILE_NAME property set. Note that a subtree with EXPORT_FILE_NAME property cannot nest a subtree with the same property set. If you can analogize with the branch/leaf data structure terminlogy, then the subtrees with EXPORT_FILE_NAME property need to be leaf nodes.

• If the file is intended to be exported as a whole (i.e. has the #+title keyword), export the whole Org file to a Hugo post in Markdown.

C-c C-e H A

Export all “What I Mean”. This is same as executing (org-hugo-export-wim-to-md :all-subtrees) in Emacs Lisp.

• If the Org file has one or more ‘valid Hugo post subtrees’, export them to Hugo posts in Markdown.
• If the file is intended to be exported as a whole (i.e. no ‘valid Hugo post subtrees’ at all, and has the #+title keyword), export the whole Org file to a Hugo post in Markdown.

For only the one-post-per-file flow #

C-c C-e H h

Export the Org file to a Hugo post in Markdown. This is same as calling the org-hugo-export-to-md function interactively.
