Source obtained from http://sourceforge.net/projects/wmacpi/files/. 2007 July 14 2.2rc1 Major changes to command line handling and to the way we use libdockapp, courtesy of Patrice Dumas. This should hopefully fix several long-standing bugs with non-wmaker window managers (in particular Debian bugs #280495 and 293546). Updated to support newer kernels that no longer support /proc/acpi/info - thanks to Samuel Ortiz. Fixed a longstanding issue with redrawing - thanks to Vito Caputo. This version changes a number of command line options (little used ones, but they're still incompatible changes) due to the libdockapp work. In particular, -w becomes -x, -v becomes -V (and takes an argument rather than being repeated), and -V becomes -v (thanks to libdockapp grabbing -h, -v and -w for itself). Also, long options are now supported for everything in wmacpi (but not acpi, since it doesn't use libdockapp for command line parsing).

**********************************************************************
|
|
|
|
wmacpi is a dockapp ACPI battery monitor for modern kernels (ie,
|
|
2.4.17 or later, and 2.6 kernels). Basically, it opens various files
|
|
under /proc/acpi, reads status information from them, and then
|
|
displays summaries.
|
|
|
|
Version 1.99 and later provides full support for multiple batteries.
|
|
You can tell it to monitor a particular battery with the -m option,
|
|
which will display the percentage remaining and current status message
|
|
for that battery. The time remaining and AC/battery status are global
|
|
- the time remaining is calculated based on all batteries found on the
|
|
system. When charging, the time displayed is the time remaining until
|
|
the battery is fully charged - this only works sensibly if your ACPI
|
|
system is implemented properly (far, far too many laptops have
|
|
buggered ACPI implementations).
|
|
|
|
The displayed time is averaged over 50 samples, each taken every three
|
|
seconds (by default). This greatly improves the accuracy of the
|
|
numbers - on my laptop, the time remaining seems to be overstated by a
|
|
good hour or so if you only sample once compared to fifty times.
|
|
|
|
Some ACPI implementations are stupid enough to block interrupts while
|
|
reading status information from the battery over a slow bus - this
|
|
means that on such b0rken laptops, running an ACPI battery monitor
|
|
could affect interactivity. To provide a workaround for this, current
|
|
versions of wmacpi supports setting the sample rate from the command
|
|
line. The --sample-rate option specifies the number of times the
|
|
battery is sampled every minute - the default is 20, and the maximum
|
|
value is 600. Since -s 600 translates to sampling every 0.1 seconds,
|
|
you really don't want to do that unless you're just having fun . . .
|
|
|
|
Also provided is a command line tool to report the battery status. By
|
|
default this will only sample once, but with the -a option you can
|
|
specify a number. Be aware that it will try to take all those samples
|
|
in the space of one second, so if your ACPI implementation is b0rken
|
|
this could have adverse effects.
