unset env variables when session is closed

[basbebe]

After unsuccesfully trying to reattach to a session, environment variables should be unset I guess.

[alexherbo2]

How?

[basbebe]

something like

:attach

#!/bin/sh

# Reattach to the session.
kak -c "$KAKOUNE_SESSION" "$@"

exit_status=$?
if [ $exit_status -ne 0 ] ; then
    unset IN_KAKOUNE_CONNECT
    unset KAKOUNE_SESSION
    unset KAKOUNE_CLIENT
fi

(maybe in an extra function – sorry for not opening a PR)

[basbebe]

or even

exit_status=$?
if [ $exit_status -ne 0 ] ; then
    exit
fi

[basbebe]

probably a :quit function would be a good approach (with alias q)?

and in each function:

exit_status=$?
if [ $exit_status -ne 0 ] ; then
    :quit
fi

[basbebe]

different but related (open new issue or put to trash?):

If a session is killed, kill all related windows:

• that :nnn that is still open? kill it (pid needs to be remembered)
• that kak-shell that is still open? exit it

I remember @occivink telling the underlying terminal used in the terminal alias doesn’t necessarily expose a PID.

I remember @occivink telling the underlying terminal used in the terminal alias doesn’t necessarily expose a PID.

then what I had in mind would of course not be feasible without the overhead of loops and hooks or environment variables storing the PIDs.

but nevertheless I would find a :quit function useful which would automatically be invoked when the session is lost.

[alexherbo2]

What is the content of the :quit command?

[basbebe]

probably just exit.

maybe also a :kill which does :send kill?

But of course both are not necessary for functionality.

[alexherbo2]

How about @ aliased to :send, so that you can:

@ kill

[basbebe]

@ kill

great!
