# Easy way to enable log on systemui without reboot.

# HOW TO USE
# TAG - tag name, e.g. ZenModePanel, usually it is class name.
# priority - the priority of log, could be (default: V):
#     v - Verbose (lowest priority)
#     d - Debug
#     i - Info
#     w - Warning
#     e - Error
#     f - Fatal
#     s - Silent (highest priority, on which nothing is ever printed)
# Commands:
# ~$ ./systemuilog [TAG] [priority]
#
# Example 1:
# ~$ ./systemuilog ZenModePanel
#
# Example 2:
# ~$ ./systemuilog ZenModePanel w

# Handle input arguments
if [ -z "$1" ]; then
    echo "ERROR: No argument supplied"
else
    # Set priority
    PRIORITY="VERBOSE"
    if [ -n "$2" ]; then
        if [ "$2" == "d" -o "$2" == "D" ]; then
            PRIORITY="DEBUG"
        elif [ "$2" == "i" -o "$2" == "I" ]; then
            PRIORITY="INFO"
        elif [ "$2" == "w" -o "$2" == "W" ]; then
            PRIORITY="WARNING"
        elif [ "$2" == "e" -o "$2" == "E" ]; then
            PRIORITY="FATAL"
        elif [ "$2" == "f" -o "$2" == "F" ]; then
            PRIORITY="SILENT"
