Hello,

first I want to thank you all for org-mode 7.9! The list of changes is
incredible!

While testing the new exporter we encountered problems with entities. We
tried to make ligations work. In LaTeX you write '\/' for a ligation
e.g. 'f\/ifteen'. To achieve that we set `org-entities-user':

#+BEGIN_SRC emacs-lisp
  (setq org-entities-user
        '("Ligatur" "\\/" nil "" "" "" ""))
#+END_SRC

The following text is used to show the problem:

  Dies ist eine Ligatur: f\/ifteen \alpha ab\-cd.

With the old exporter the translation to LaTeX is:

  Dies ist eine Ligatur: f\/ifteen $\alpha$ ab\-cd.

Which is the expected result. With the new exporter we get:

  Dies ist eine Ligatur: f$\backslash$/ifteen $\alpha$
  ab$\backslash$-cd.

As you can see the shy hyphen is also wrong. But \alpha is exported
correctly. So I don't know what is happening here.

You have defined an entity named "Ligatur". If you want to apply it
during export, you have to write either \Ligatur or \Ligatur{}. For
example, \alpha is correctly exported since there is:

  ("alpha" "\\alpha" t "&alpha;" "alpha" "alpha" "α")

in `org-entities'.

Note that old exporter doesn't apply your entity either (entities usage
doesn't change between both exporters). It just gives up each time he
sees a backslash which isn't followed by a known entity name, assuming
this will be handled by LaTeX.

HTH,

thanks for explaining. I now have:

#+BEGIN_SRC emacs-lisp
  (setq org-entities-user
      '(("lig" "\\/" nil "" "" "" "")))
#+END_SRC

Now it works as expected and explained by you. There was an error in my
initial version. It was only a list not a list containing lists.

Thanks again.

Actually, I overlooked the second part of your example:

  Dies ist eine Ligatur: f\/ifteen \alpha ab\-cd.

ab\-cd should be exported as-as, not as ab$\backslash$-cd, since "\-" is
considered as a special string (see `org-export-with-special-strings').

I fixed that mistake in the new exporter.

Thanks again.
