In fact, calling octave -qf --no-line-editing from an X terminal exhibits the same problem. Nice that you have found the cause :) >I think there are two possible ways forward. This can be discussed with >the Emacs maintainers to see if that option can be removed. I doubt it. I'd bet that the octave-inferior mode is based on comint, which manages the line editing itself. This is for simplicity and for consistency with the Emacs environment. In fact, I set gnuplot as the plotting engin in my .octaverc and I keep regularly using Octave under Emacs. > If Octave >does run readline, does it fatally break the inferior mode interface to >Emacs, or is it just doing extra work and the mode authors thought they >would be saving some overhead? The Emacs interface should be completely rewritten for inferior-octave to avoid using comint. This is not impossible, but I think it is a significant work. Obviously, there may be people that have an excellent grasp on Emacs lisp that want to do the job, so don't just take my word for it. >Another way is to simply prevent the fltk toolkit from being selected as >the active toolkit when readline is disabled in Octave.

This should definitely be done, and only removed the moment Octave is made to work with fltk even while using --no-line-editing. Additionally, when using --no-line-editing, attempts to change the graphics engine to fltk should elicit a warning or something like that. >Of course, if you or anyone else can show a case where this fltk problem >still happens without the --no-line-editing option and outside of Emacs >mode, then there may still be an undiagnosed problem with fltk.
