Hi Eric, C-g works to get out of the "frozen" state. I feel silly for not trying it. Shell mode (M-x shell) doesn't have a similar "freezing" behavior, which led me to think it might be a bug -- but it looks like this is how comint is supposed to work (R/ESS inferior process behaves just like Matlab, for instance). --Leo On Mon, Mar 14, 2011 at 9:19 AM, Eric Ludlam <Eri...@ma...> wrote: > RET is bound by comint mode, and matlab-shell just does whatever comint does. comint is a library used for defining modes that interact with a shell like command.

Enabling debugging (M-x toggle-debug-on-quit) would help if it were possible to quit, which leads me to believe it is in a filter or one of the hooks that prevents C-g from working. > > Eric > > -----Original Message----- > From: Leo Alekseyev [mailto:dn...@gm...] > Sent: Sunday, March 13, 2011 4:41 AM > To: mat...@li... > Subject: [Matlab-emacs-discuss] Possible bug: emacs unresponsive if hit RET multiple times at the end of matlab command > > Tested with Matlab mode 3.3.1, several recent versions of Emacs. > Steps to reproduce: > M-x matlab shell > pause(10) > RET RET RET > > Here, pause(10) can be any command that doesn't return immediate result. > > Expected result: Matlab command runs in matlab-shell buffer, Emacs can > be used as normal.
