The fact is, exit status is application-dependent on Unix systems, POSIX or not. Even if POSIX defines how vi should behave on exit, the operating system has no means to enforce this behavior, and authors of vi clones need not adhere to it if they so choose. For that matter, there is no reason the user is required to run vi or any POSIX-compliant program as Mutt's editor. A user could choose to use a script which modifies a template as his editor, and that script might return the number of changes it made, the day of the week, or whatever other value the author decided to pass back to the OS. Mutt can not know what the exit status of $EDITOR will indicate, and as such Mutt MUST ignore it. > Then again, what is an error in an interactive program? Exactly. Presumably, the user will be able to identify a failure of the editor, and take actions to correct before the editor finishes. > Do you have any suggested alternative solution for the problem > reported in that bugreport? http://dev.mutt.org/trac/ticket/1638 Yes: do nothing. The only thing Mutt should care about is whether the temp file changed since Mutt created it. Not detecting a failure in the editor is NOT a bug. It's the only sensible behavior. The OP's problem proves this. -- Derek D. Martin http://www.pizzashack.org/ GPG Key ID: 0xDFBEAD02 -=-=-=-=- This message is posted from an invalid address.
