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 "\n\norg-use-sub-superscripts: ")
(if
(eq org-use-sub-superscripts t) "t\n"
(if (eq org-use-sub-superscripts '{}) "{}\n"
(if (eq org-use-sub-superscripts nil) "nil\n" "not nil\n"))))
(insert "plain underscore: X_sub 3^super\n")
(insert "braces : X_{sub} 3^{super}\n")
(push-mark)
(insert "plain underscore: X_sub 3^super\n")
(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
