# ECB Rates
|
|
|
|
A cli utility to fetch the currency rates against the Euro from the ECB.
|
|
|
|
## Install
|
|
|
|
First, make sure that you have the rust toolchain installed. If not, then go to [rustup](https://rustup.rs) to install it.
|
|
|
|
Now, Git clone the project, then cd into the projects root-dir. Thereafter run:
|
|
|
|
```sh
|
|
cargo install --path .
|
|
```
|
|
|
|
Congratulations! Now the cli binary `ecb-rates` will be in your cargo bin folder.
|
|
|
|
## Features
|
|
|
|
#### Fetch as many days as you want
|
|
|
|
It will fetch any of the following api nodes, and reduce them for you.
|
|
|
|
- Last available day.
|
|
- Last 90 days
|
|
- Since the dawn of the *EUR*
|
|
|
|
#### Display select currencies
|
|
|
|
- as an ASCII table
|
|
- in JSON prettified
|
|
- in JSON minified
|
|
|
|
#### Cache
|
|
|
|
It features an extensive cache, which will [calculate hollidays](src/holiday.rs) in order to know whether to invalidate it or not.
|
|
|
|
#### Show the rates in your way
|
|
|
|
Change the rates for the perspective of any currency with the `--perspective` or `-p` flag.
|
|
|
|
Flip it from `EUR to ALL` to `ALL to EUR` with the `--invert` or `-i` flag. It will work as expected with the *perspective* option.
|
|
|
|
#### Fast
|
|
|
|
It wouldn't be a rust project without being *BLAZINGLY FAST*! When the cache is valid a single day will on my computer be shown in 3 ms. When the cache isn't being used it will be ~90ms. The cache speed will largely depend on your drive, the latter will depend on your network speed. Both options are fast enought to be in a `.bashrc` or `.zshrc`
|
