# Description
 | 
			
		||||
This tool "traduit" (french for translate) data formats. It was made in the hope to bring serde to the cli (serdi ^^). But that not exaclty what serde is about and I have no affiliation with them so I did not want to namesquat.
 | 
			
		||||
 | 
			
		||||
# Installation
 | 
			
		||||
First install [the rust toolchain](https://www.rust-lang.org/tools/install) and then execute the following command:
 | 
			
		||||
```sh
 | 
			
		||||
cargo install tradaf
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
# Usage example
 | 
			
		||||
Prettify (or minify) some data format for ease of reading (resp: compact and have less data to save/transfert)
 | 
			
		||||
```sh
 | 
			
		||||
tradaf json json --pretty < simple.json 
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
Litterally transcode between data formats
 | 
			
		||||
```sh
 | 
			
		||||
tradaf ron yaml < examples/standard.ron
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
Transcode into JSON so we can use `jq`, do some transformations and then transcode again into another format for viewing
 | 
			
		||||
```sh
 | 
			
		||||
tradaf RON json < examples/gameConfig.ron | jq .key_bindings | tradaf Json yaml
 | 
			
		||||
```
