Emacs Battery mode cannot use iBook

Emacs Battery mode cannot use iBook

[Sam Lauber]

I have a iBook G4 w/ Mac OS X.  I installed the Carbon Emacs from June '05.  
But the Battery mode does not know about the Mac OS X programs for
battery status, so it dosen't know the battery status for the laptop when
the system provides this information already.  

Samuel Lauber

P.S.  The battery information can be found by calling the program `pmset
-g ps'; it outputs information in the following format:

  Currenty drawing from 'POWER_SRC Power'
   -InternalBattery-0     XX%; STATUS; ESTIMATE

where `POWER_SRC' is either AC or Battery.  XX is the percentage of charge.  
(N.B.  It is never 100%; the highest value that my iBook will give is 99%).  
STATUS is either `AC attached' (power adapter plugged in and battery fully
charged), `discharging' (running off battery power and taking power out of
the battery), or `charging' (charging up).  If the battery is out, the entire
`XX%; STATUS...' line is replated with `(removed)'.  Note that the first
line has a typo.  It might get fixed, so don't rely on it.

battery.el currently only knows how to get battery information from a
Linux kernel.  I'll see if I can add support for iBooks running OS X.
Is calling "pmset -g ps" the canonical way to get battery information
on OS X?  (Is that program typically installed?)

pmset is at installed on my Mac OS X 10.3 (Panther), but it doesn't
know the `ps' option. Is that part of pmset specific to 10.4 (Tiger)?

Yes.  It is installed with the base install of Mac OS X.   

Samuel

P.S.  I'd say it would be canonial, but agian, most userspace programs don't
need to know this kind of thing.

Plugged into adapter and fully charged:

Currenty drawing from 'AC Power'
 -InternalBattery-0     99%; AC attached; not charging

Running off battery power:

Currenty drawing from 'Battery Power'
 -InternalBattery-0     99%; discharging; 4:35 remaining

Running off battery power, but still estimating how much time left:

Currenty drawing from 'Battery Power'
 -InternalBattery-0     99%; discharging; (no estimate)

Battery not connected:

Currenty drawing from 'AC Power'
 -InternalBattery-0     (removed)

Charging up:

Currenty drawing from 'AC Power'
 -InternalBattery-0     50%; charging; (no estimate)

Charging up, but knowing how much time we have left:

Currenty drawing from 'AC Power'
 -InternalBattery-0     50%; charging; 3:07

It says ``Battery status not avaliable'' in the minibuffer.
