If last battery is not present, no info is retrieved at all

[Tux]

if /pro/acpy/info has BAT0 and BAT1 and both have info and state and the last has content

present: no

Which would result in an error like

Use of uninitialized value $battery{"charging_state"} in string ne at …/bin/rainbarf line 387.

It overrules earlier batteries found. The loop should probably be changed to

        if (grep {
                -d $_
                and -e ($acpi_info  ||= qq($_/info))
                and -e ($acpi_state ||= qq($_/state))
            } sort glob q(/proc/acpi/battery/BAT[0-9])
        ) {
            for my $file ($acpi_info, $acpi_state) {

I changed = to ||=.

Thanks for spotting this! I've updated the code & refactored the whole battery info retrieval, could you please check if it is working fine for your setup?

god, I hate Module::Build :(

I'd expect rainbarf --help to return the synopsis, not the whole manual page. That'd better be rainbarf --man, rainbarf --info or whatever

$ rainbarf --battery --bolt --remaining --bright --loadavg --swap

colored in my xterm. So yes, it works

Eh, indeed, that documentation was designed to look good as markdown, on GitHub. Perhaps I'll just print synopsis+URL and mention the fact that perldoc rainbarf is what one wants when no GUI/Internet is reachable :)
