Hey,

I want to use this awesome project in polybar via shell script. But i can't figure it out how to compile cli or ffi. I installed battop via yay battop. It works perfectly.

Actually, i couldn't see a installation guide or it could be a not-well documented. Simply,

1. When i run this: cargo install battery-ffi

Returns:

Updating crates.io index
  Installing battery-ffi v0.7.0
error: specified package has no binaries

2. battop is not supporting output args like this:

battop --time-to-empty

It may be really really life saver.

3. cargo build --release

Returns:

error: failed to resolve patches for `https://github.com/rust-lang/crates.io-index`

Caused by:
  patch for `battery` in `https://github.com/rust-lang/crates.io-index` did not resolve to any crates. If this is unexpected, you may wish to consult: https://github.com/rust-lang/cargo/issues/4678

The bare-minimum thing I want is looks like:

$ battery-cli --time-to-empty

Consequently, I want to write the battery's battery_get_time_to_empty output to the polybar. I am trying to figure it out how to write a script that scrapes about battery informations.

Setup:

fn main() {
    let batteries = battery::Manager::new().iter().collect::<Vec<_>>();
    println!("{:#?}", batteries);
}

There LICENSE-APACHE and LICENSE-MIT files on github, but no license files on crates.io. Could you add them? This is mandatory for some Linux distros if we want to package rust-battery for official repos.

Updates the requirements on core-foundation to permit the latest version.

Dependabot will resolve any conflicts with this PR as long as you don't alter it yourself. You can also trigger a rebase manually by commenting @dependabot rebase.

According to https://github.com/starship/starship/issues/613#issuecomment-548873632, there exist a possibility when both energy_full_design and charge_full_design files are missing for the battery device, so fetching fails with an error here: https://github.com/svartalf/rust-battery/blob/08b2ad579d135dbe48d52ff31a35df307c173eb6/battery/src/platform/linux/sysfs/source.rs#L183

upower just falls back to 0.0 value, but that might affect state_of_health

Amperage was returning negative values, so I changed it to read as an isize and then getting the absolute value from it.

percentage() was also overflowing. I changed it to use the capacity values directly instead of going through the energy functions. The multiplication with voltage should cancel out either way.

InstantTimeToEmpty is returning the time in minutes, at least on my system. I haven't gotten InstantTimeToFull to report anything yet, instead it's reporting both values through TimeRemaining. (I haven't looked into this, just mentioning it)

I have only tested this on Mojave (10.14.3)

The multiplication in percentage overflowed the u32 integer type before multiplication. Before, the operator precedence multiplied self.energy() by 100 which overflowed. The fix converts the energy and energy_full to floats and computes the ratio, before multiplying by 100 which prevents the overflow.

When i run cargo build --release I am getting this:
