# Convert Case

Converts to and from various cases.

## Rust Library `convert_case`

Convert case was written in Rust and is ready to be used inline with your rust code as a library.
```{rust}
use convert_case::{Case, Casing};

assert_eq!("ronnieJamesDio", "Ronnie_James_dio".to_case(Case::Camel));
assert_eq!("io_stream", "IOStream".to_case(Case::Snake));
assert_eq!(
    "2020-04-16 My Cat Cali",
    "2020-04-16_my_cat_cali".from_case(Case::Snake).to_case(Case::Title)
);
```
You can read the API documentation on [docs.rs](https://docs.rs/convert_case/) for a list of all features and read lots of examples.  Bonus: this crate has _0 dependencies!_

## Command Line Utility `ccase`

The command line utility `ccase` was made to leverage the tools in the `convert_case` library.
```
$ ccase -t title super_mario_64
Super Mario 64

$ ccase -f snake -t title 2020-04-15_my_cat_cali
2020-04-16 My Cat Cali

$ ccase -t camel "convert to camel"
convertToCamel
```

You can read more about the `ccase` executable in the [`ccase` directory](https://github.com/rutrum/convert-case/tree/master/ccase) within this repository.
