Hi guys,
This is the third time I'm trying to post on this list, hopefully it'll work.
First, I'd like to thank Tuomo and all other who have contributed
to make ion such a great w. manager.
Second, sorry for not continuing with the existing thread on battery info
meter and such, but when that thread started I wasn't registered to
this list.
I have some older code which was also doing the battery
meter thing, plus some other meters: network interface and ip address
meter (including wifi), cpuspeed, etc. I'll just append it below, and if
anyone has use of it or wants to change it, so
be it. The main difference is that this code will work with apm, as
my acpi isn't yet there (buggy) on my thinkpad.
Please take this code with a grain of salt; I'm new to lua and ion. Any
suggestions for improvement are certainly welcome.
Best regards,

In .ion3/cfg_statusbar.lua, I personally use the minimal wifi info as follows:
template="%cpuspeed MHz .. %batt .. %iface%inet_addr%iw_info_min
.. %date",

agreement as the ion3 code.
