Bug: latex export [7.01trans (release_7.01h.613.g17c71)]

[markscala]

I use org and latex export to write logic exercises and tests for my
classes, and I've noticed the following problem.  In the following
items, all but the last item export correctly:


P \rightarrow Q

P \vee Q

P \& Q

P \leftrightarrow Q

P \vdash Q


Here is the output for C-c C-e L:


P $\rightarrow$ Q

P $\vee$ Q

P \& Q

P $\leftrightarrow$ Q

P \vdash Q


The last item in this list should be P $\vdash$ Q.

Thanks,
Mark Scala

This occurs because \vdash is not defined in org-entities, while the
other symbols are. If you want it to export properly to LaTeX, you can
add something like the following to your ~/.emacs:

(add-to-list 'org-entities-user '("vdash" "\\vdash" t "⊢" "|-" nil "⊢"))

For more information, type

C-h v org-entities
C-h v org-entities-user

Best,
Matt
