Yes, but currently you assume that the prompt ends with ">+ ". So why not simplify the regexp and make it more general by simply changing it to "^[^>]+>+ "? With respect to the current default, it has the disadvantage that it would be fooled by prompts containing more than one instance of '>', but would have the advantage of matching anything that ends with ">+ ", including all the prompts matched by the current regexp.

Well, it doesn't work, as my problem shows: if I set PS1 inside .octaverc to something that is not matched by inferior-octave-prompt then the filter hangs. >But I'm no longer sure how all this is supposed to work. And, sorry, I have not the time now to debug this :-( Anyway, since it doesn't work, I make a second proposal: until someone corrects it, from octave-inf.el remove the lines: (if (not (string-equal inferior-octave-output-string ">> ")) "PS1=\"\\\\s> \";\n") >| >problem of people changing the prompt during a session. >| In principle, the inferior octave mode could detect this and adjust >| comint-prompt-regexp accordingly. >How would you detect the change? You can set comint to do something depending on the given command. For example, shell mode detects when the user uses the "cd" command, reads its argument and changes the current directory accordingly. shell-directory-tracker does it, but it is very complex: for octave it should be much simpler. -- Francesco Potort́ (ricercatore) Voice: +39 050 315 3058 (op.2111) ISTI - Area della ricerca CNR Fax: +39 050 313 8091 via G.
