hi list,
i am not sure whether i have discovered a bug or just using this not in
the right way.
i have an org document where i have lots of underscores in words (they
are function names, e.g. BC_send) and do not want them to be interpreted
as subscripts.
the documentation says that the variable org-use-sub-superscript can be
used to customize this behaviour:
- t..convert every underscore
- {}..only convert when text is preprended by an underscore and within
braces
- nil..no conversion at all
in my environment, this does not work. output is always the same.
i exported to html.
i have set the variable in my
.emacs. i have also tried without my defs with emacs -q --no-desktop.
i found a similar report on the list, where they tried #+OPTIONS, this does
also not fix
my problem.
finally i have wrote a little elisp file to programmatically reproduce
my situation, here it is:
------------cut-----------------------
(defun insert-version ()
  "insert org and emacs version information"
  (interactive)
  (insert (concat "emacs-version: " emacs-version "n"))
  (insert (concat "org-version: " org-version "n")))
(defun insert-org-text ()
  "insert some org text with sub and superscripts
and select the org text"
  (interactive)
  (insert (concat "nnorg-use-sub-superscripts: ")
            (if
                      (eq org-use-sub-superscripts t) "tn"
                  (if (eq org-use-sub-superscripts '{}) "{}n"
                          (if (eq org-use-sub-superscripts nil) "niln" "not
niln"))))
  (insert "plain underscore: X_sub 3^supern")
  (insert "braces          : X_{sub} 3^{super}n")
  (push-mark)
  (insert "plain underscore: X_sub 3^supern")
  (insert "braces          : X_{sub} 3^{super}n")
  (exchange-point-and-mark))
(progn
  (let ((orgfile "blaa.org"))
    (get-buffer-create orgfile)
    (set-buffer orgfile)
    (split-window-horizontally)
    (switch-to-buffer-other-window orgfile)
    (kill-region (point-min) (point-max))
    (org-mode)
    (insert-version)
    (setq values '(t {} nil))
    (while values
      (setq org-use-sub-superscripts (car values))
      (insert-org-text)
      (org-html-convert-region-to-html)
      (setq values (cdr values)))))
-------------cut---------
and here is my output:
-------------cut---------
emacs-version: 24.3.1
org-version: 8.2.3b
org-use-sub-superscripts: t
