jase

====

A simple command line utility for extracting data from and writing data to JSON-formatted data structures.

```

Usage:

  jase  [options]

Arguments:

       A dot (`.`) delimited key which references the value that should be returned or overwritten.

            Escape dot characters in key names using '\', e.g. 'config.foo\.bar'.

Options:

  -f, --file           The JSON file to read.

  -s, --set          The new value to set for the provided key.

  -d, --delete               Delete the provided key.

  -i, --indent       The number of spaces to indent the newly written JSON.

Example:

  jase ./package.json scripts.test

```

### Basic Examples

#### Retrieve a value (specifying a JSON file)

```bash

$ jase scripts -f package.json

{

  "test": "tape test/*.js"

}

$ jase scripts.test -f package.json

"tape test/*.js"

```

#### Retrieving a value (piping JSON to stdin)

```bash

$ cat ./package.json | jase scripts

{

  "test": "tape test/*.js"

}

$ cat ./package.json | jase scripts.test

"tape test/*.js"

```

### Sample Uses

#### Get a property

```bash

$ cat package.json | jase author

```

#### Get a nested property

```bash

$ cat package.json | jase scripts.test

```

#### Add a property

Chain operations and do things like add nested properties.

```bash

$ cat package.json | jase config -s {} | jase config.port -s 8000

```

#### Delete a property

```bash

$ cat package.json | jase scripts -d

```

#### Reformat a file

Convert a JSON file with 2-space indenting to 4-space

```bash

$ cat package.json | jase "" -i 4

```
