# OCPI tariffs CLI
This crate provides a binary for doing calculations with [OCPI](https://evroaming.org/ocpi-background/)
[tariffs](https://github.com/ocpi/ocpi/blob/2.2.1/mod_tariffs.asciidoc#1-tariffs-module).
Specifically for the [`OCPI 2.2.1`](https://evroaming.org/app/uploads/2021/11/OCPI-2.2.1.pdf)
and [`OCPI 2.1.1`](https://github.com/ocpi/ocpi/releases/download/2.1.1-d2/OCPI_2.1.1-d2.pdf) version.
## Installation
First install [Rust](https://www.rust-lang.org/tools/install) and then install
the OCPI tariffs command line tool:
```text
cargo install ocpi-tariffs-cli
```
## Usage
The binary can be directly executed using `ocpi-tariffs`. Execute `ocpi-tariffs
--help` for a list of subcommands.
### Subcomamands
#### Price
Use the `price` command to price a tariff and CDR (Charge detail record) and see a breakdown of the
periods and compare the CDR totals with the calculated:
```text
Price a given charge detail record (CDR) against either a provided tariff
structure or a tariff that is contained in the CDR itself.
This command will show you a breakdown of all the calculated costs.
Usage: ocpi-tariffs price [OPTIONS]
Options:
-c, --cdr <CDR>
A path to the charge detail record in json format.
If no path is provided the CDR is read from standard in.
-t, --tariff <TARIFF>
A path to the tariff structure in json format.
If no path is provided, then the tariff is inferred to be contained
inside the provided CDR. If the CDR contains multiple tariff
structures, the first valid tariff will be used.
-o, --ocpi-version <OCPI_VERSION>
The OCPI version that should be used for the input structures.
If the input consists of version 2.1.1 structures they will be converted to 2.2.1 structures.
The actual calculation and output will always be according to OCPI 2.2.1.
use `detect` to let to tool try to find the matching version.
[default: v221]
[possible values: v221, v211, detect]
-z, --timezone <TIMEZONE>
Timezone for evaluating any local times contained in the tariff
structure
[default: Europe/Amsterdam]
-h, --help
Print help (see a summary with '-h')
