Two emacs packages are required for converting adoptingerlang.org to pages for the Hugo website or LaTeX for conversion to pdf, mobi, etc. The following can be added to the beginning of your ~/.emacs.d/init.el file if you have one or create that file with this content:
(require 'package)
(add-to-list 'package-archives '("melpa" . "http://melpa.org/packages/"))
(add-to-list 'package-archives '("marmalade" . "http://marmalade-repo.org/packages/"))
(add-to-list 'package-archives '("gnu" . "http://elpa.gnu.org/packages/"))
(package-initialize)
;; Bootstrap `use-package'
(unless (package-installed-p 'use-package)
(package-refresh-contents)
(package-install 'use-package))
(eval-when-compile
(require 'use-package)
(require 'package))
(dolist (package '(use-package))
(unless (package-installed-p package)
(package-install package)))
(use-package org
:ensure t
:mode (("\\.org\\'" . org-mode))
:config
(progn
(setq org-startup-indented t)
(add-hook 'org-mode-hook #'visual-line-mode)
(setq org-src-fontify-natively t)))
(use-package org-bullets
:ensure t
:commands (org-bullets-mode)
:init (add-hook 'org-mode-hook (lambda () (org-bullets-mode 1))))
(use-package ox-hugo
:ensure t)See https://ox-hugo.scripter.co/doc/formatting/ for basic Org formatting compared to the Markdown equivalent.
To export a section to its Hugo markdown page move the cursor to the section in adoptingerlang.org and run M-x org-hugo-export-wim-to-md. This will create or update content/docs/<section filename>.md.
The side menu is setup in content/docs/menu/index.md.
Exporting to latex is done with M-x org-latex-export-to-latex.
Easiest way to convert to a pdf is to just use a LaTeX docker image:
$ docker run --rm -it -v .:/source schickling/latex
# pdflatex adoptingerlang.texThese are instructions for how we create snapshots.
First, create a variable with the date in format <year>-<month>-<day>:
$ DATE=`date +"%Y-%m-%d"`
In Netlify under Branches and deploy contexts add the branch ${DATE} to the
list of Branch deploys.
Next, create a branch with today's date, prefixed by s-:
$ git checkout -b s-${DATE}`
Edit config.toml to set the version to the current date:
[params]
version = "${DATE}"
Add a row to the menu in ./themes/custom/layouts/partials/docs/menu.html using
that version as the subdomain and check for which row to have selected:
<option value="http://${DATE}.adoptingerlang.org" {{if eq
.Site.Params.Version "${DATE}" }}selected{{end}} >${DATE}</option>
Commit those changes:
$ git commit -a -m "create snapshot-${DATE}"
Push to the branch and create a new tag, snapshot-${DATE} to push:
$ git push origin s-${DATE}:s-${DATE}
$ git tag -s snapshot-${DATE} -m "snapshot of site on ${DATE}"
$ git push origin snapshot-${DATE}
This will trigger Push snapshot branch in Github Actions which will create the
branch ${DATE} after building the site so that Netlify can deploy the content.
Finally, update DNS to point a CNAME for the Netlify branch deploy, CNAME ${DATE} -> ${DATE}-subdomain.netlify.app.
