Hello, I have the following macro to aid in presenting calculations in solutions to coursework questions etc. for my teaching:
#+macro: calculate src_calc[:exports code]{$1} = @@latex:\fbox{@@ src_emacs-lisp{(setq var-$2 (string-to-number (calc-eval "evalv($1)")))} \to $2 @@latex:}\\@@ The "\to" which org catches and converts to → on export causes a problem with font-locking: Error during redisplay: (jit-lock-function 1) signaled (wrong-type-argument vectorp →) Using math mode directly, i.e. \(\to\) works just fine, at least for LaTeX export, but I thought I'd mention this anomaly in case it bites anybody else! thanks, eric -- : Eric S Fraga (0xFFFCF67D), Emacs 25.0.92.1, Org release_8.3.4-705-g716e33
