Thank you for your answer. Here it is: 1. Create the following directory structure (3 directories): ~/test/ ├── content ├── html └── .packages
2. Create the .el script to build the website (=~/test/build.el=): #+begin_src elisp ;; * Set the package installation directory (in order not to overwrite the standard ~/emacs.d) (require 'package) (setq package-user-dir (expand-file-name "./.packages")) (setq package-archives '(("melpa" . "https://melpa.org/packages/"))) (add-to-list 'package-archives '("elpa" . "https://elpa.gnu.org/packages/")) ;; * Initialize the package system (package-initialize) (unless package-archive-contents (package-refresh-contents)) ;; * Install dependencies ;; ** since org is builtin, by default Emacs does not try to install the latest version from Elpa (9.5.4) ;; the following solves the issue: (defun mpger-ignore-builtin (pkg) (assq-delete-all pkg package--builtins) (assq-delete-all pkg package--builtin-versions)) (mpger-ignore-builtin 'org) ;; ** install packages: (package-install 'org) (package-install 'htmlize) ;; * Load the publishing system: (require 'org) (require 'htmlize) (require 'ox-publish) ;; * Define the project (setq org-publish-project-alist (list (list "pages" :recursive t :htmlized-source t :base-directory "./content/" :base-extension "org" :publishing-directory "./html/" :publishing-function 'org-html-publish-to-html :with-creator t :with-toc t :section-numbers nil :time-stamp-file nil) )) ;; * Generate the site output (org-publish-all t) (message "Done!") #+end_src 3. In =~/test/content/=, create a simple test.org file to be published as html (=~/test/content/test.org=): #+begin_example * Here's some text Lorem ipsum. * Here's some code #+begin_src R :results output :exports both df <- mtcars ## a comment library(parallel) #+end_src #+end_example 4. Run =~/test/build.el= (e.g. with ~emacs -Q --script ~/test/build.el~) and compare with the output from ~C-c C-e h o~. The latter has syntax highlighting, the former has not.
