check if vb is already open

[Francesco Apollonio]

Only one instance of virtualbricks can be executed at the same time, vb has to use a lock file (under /tmp) to check if another instance is already running

virtualbricks._settings is meant to be private and virtualbricks.scritps.virtualbricks is just a wrapper to virtualbricks.scripts.gui

Maybe that code is better in virtualbricks.app

[Francesco Apollonio (lorddex)]

OK, I will move the code in the app file

Just a thought, what about a shell script that do that? Something like

    LOCKFILE=/tmp/vb.lock
    if lockfile -r0 $LOCKFILE 2> /dev/null; then
        virtualbricks
    else
        Another Virtualbricks instance is running. If this is an error, please delete $LOCKFILE to start Virtualbricks
    fi

Enhanced version:

    LOCKFILE=/tmp/vb.lock
    trap "rm -f $LOCKFILE" EXIT SIGINT SIGQUIT SIGTERM
    if lockfile -r0 $LOCKFILE 2> /dev/null; then
        echo $$ > $LOCKFILE
        virtualbricks
    else
        Another Virtualbricks instance is running. If this is an error, please delete $LOCKFILE to start Virtualbricks
    fi
