;; removes ugly horizontal lines in html-exported code 
;; (not mandatory)
(setq org-html-keep-old-src t)

;; As ob-julia.el and ox-bibtex are less common, 
;; we use a local repository.
;;
;; Usage: emacs -q --load emacs_files/init.el
;;
;; In a more usual setting one should use:
;; (require 'ob-julia.el)
;; (require 'ox-bibtex)
(load-file "emacs_files/ob-julia.el") ; works with ess-site, our notebook engine
(load-file "emacs_files/ox-bibtex.el"); used for bibliography HTML-export 

;; allows julia src block (requires ob-julia.el)
(setq org-confirm-babel-evaluate nil)

;; defines image width in the OrgMode buffer (this is not for html
;; exports, for this you must use #+HTML_ATTR: :width 900px for
;; instance)
;;
;; This is not mandatory, but useful when one uses the gr() Plots.jl
;; backend as it exports wide .png files. CAVEAT: use imagemagick for
;; image resizing.
