(failed to wide-reply initially) I just had use for this for some quick calculations I wanted to add to one of my files, but...
Any idea why variables inside of parentheses don't work, but variables outside of them do? #+BEGIN_SRC calc :var testvar=9000 testvar - 200 #+END_SRC #+results: : 8800 #+BEGIN_SRC calc :var testvar=9000 (testvar - 200) 800 #+END_SRC #+results: : 800 testvar - 160000 "Eric Schulte" <schulte.e...@gmail.com> writes: > Alright, > > I've just pushed up support for variables.
