The new syntax available in the config file is:
apm_battery [0-9]+(%|[Mm) (dis|)charging { ... }
The stuff in the braces is the same as the existing case. nn% checks for
a certain percentage of life remaining and nnM checks for a cerain
number of minutes remaining. Specifying "discharge" means that you're
interested in knowing when the battery reaches a certain level while AC
power is off, "charging" the opposite.
The man page needs to be updated.
The code can be fooled. If you SIGHUP the daemon and the battery level
matches a rule it will be performed once per SIGHUP. If the battery
level matches a rule and you repeatedly apply and take away AC power,
the rule will be run once per occurance. This, however, is a feature.
:-) The code also only runs when select() times out, so getting APM
events more often than the timeout interval will result in the rules not
being run. These are things that remain to be overcome.
