Saving all comint history in real time

Saving all comint history in real time

[Yaroslav Bulatov]

Is there something out there to save all of my comint history after
each command (as opposed to the end of the session?)
I'm using shell-mode right now, and it logs history to
.bash_history.log, but that misses any commands issued when I ssh, and
doesn't save anything until the end of the session

Try setting the environment variable HISTFILE, before starting M-x shell, 
because otherwise history won't be saved for bash (at least that's the
case in Emacs 23 which I use).

Then you can try calling (comint-write-input-ring) from M-: after typing
some commands to see if it saves the inputs to the file you set in HISTFILE.

If it does then you can add an after advise to comint-send-input to call 
comint-write-input-ring after each command.

Yes, that actually saves all the commands.
However, when I exit the shell, this file is overwritten by something
else, and new version does not include commands from subshells

Did you use some unique log file name, like myemacsshell.log?
Because if you used "bash_history" or something then it may get 
overwritten by bash itself.
