Changed definition of `parse_arguments`. `to_seconds` -> `interval_to_seconds`, and inlined. `print_version` and `print_usage` are inlined.
kwh-cost
Calculate cost of electricity.
How to use
$ kwh-cost [OPTIONS] price wattage interval [interval ..]
Options are -v, --version to show program's version; and -h, --help to show usage of a program.
price is a price per kWh. wattage is how many Watts being consumed. interval is for how long.
interval is in seconds, but you can specify a unit. Units are the following:
m for minutes; h for hours; and d for days. There could be as many intervals passed as you need.
Here is an example:
$ kwh-cost 3.68 120 30d 2h
P.S.: Yeah, I pay 3.68 rubles per kWh. Which is just $0.05. :)
Installation
Manually
First run make to build a program, and then make install to copy executable in /usr/bin/. Later, use make uninstall to delete it, or just delete /usr/bin/kwh-cost.
For ArchLinux
You can take a PKGBUILD file and in a directory with it run makepkg -i.
