Hi
I asked that more than a year ago, but maybe meanwhile there are some news in master which I did not noticed. Consider please the following template #+begin_src matlab :results output latex :exports results :eval never-export clear all f1=5; f2=4; f3=6; h=(1-(-1))/2; s=misimp(5,4,6,h); disp('\begin{equation*}') fprintf('I = %g \\\\\n', s) disp('\end{eqaution*}') #+end_src Suppose I accidentally delete the last line, so the template would be invalid. Is there, meanwhile, any command which would guess the correct template and insert the missing line? Auctex has a similar functionality called «close environment» which is a real time saver.
