I use sysutils/screen a lot, but on my netbook I also needed to keep track of the battery load. Here is my documentation:
screen has no buit-in trigger for battery status, and also doesn't seem to handle shell code very well in its .screenrc. Therefor you can use a small file that gives you the output you need and make screen read that.
To get the battery load, I installed sysutils/upower, that "listens to device events and querying history and statistics." With some found code you get the battery load percentage as output:
This sh-script is stored in my home directory. It is important to make the file executable!
Now in .screenrc you can call this script for use in the statusline:
The `backtick' line calls the script and uses `1' to refer to in the statusline code (hardstatus). The following `0' is for its lifespan and the trailing `1' is for the autorefresh interval. To trigger the backtick, the status line code should point to it with `%1`' (percentage-one-backtick).
To emphasis the battery load I gave it a yellow color. The screenshot (double meaning) is below, also giving the entire code for my status line.
I like to share my solution here, because IMHO the Forum is not just for asking, but also for telling you lot how things can be done.
TNX,
