# for all who dont like perl:
# inputlength = "{sb length: $@L}";
#
# with leading spaces: (3 spaces in example)
# inputlength = "{sb $[-!3]@L}";
#
# with leading char "-"
#
# inputlength = "{sb $[-!3-]@L}";
#
# you cant use numbers here. if you want to use the numbers use the
# perl script
#
#
# thanks to: Wouter Coekaerts <wouter@coekaerts.be> aka coekie
#
# add one of these 2 lines to your config in statusbar items section
#
# the perl scripts reacts on every keypress and updates the counter.
# if you dont need/want this the settings are maybe enough for you.
# with the settings the item is update with a small delay.
