This is a formatter for JSON strings.

JSON Formatter is specialized in formatting JSON strings that do not use regular expressions and has no functions other than formatting. Therefore it is extremely lightweight besides can be expanded to meet user needs.

Note:
Replace version you want to use. Check the latest Packages.

repositories {
    maven {
        name = "GitHubPackages"
        url = uri("https://maven.pkg.github.com/myConsciousness/json-formatter")
        credentials {
          username = "myConsciousness"
          password = "xxxxxxxxxxxxxxxxxx"
        }
    }
}

dependencies {
    implementation 'org.thinkit.formatter:json-formatter:v1.0.2'
}

import org.thinkit.formatter.json.JsonFormatter;

Formatter formatter = JsonFormatter.newInstance();

You can also create an instance with a specific number of indents as following.

Note:
If a negative indentation is passed at instantiation time, the initial value defined in the content file takes precedence.

Formatter formatter = JsonFormatter.from(indent);

Formatter formatter = JsonFormatter.from(indent);
String formattedJson = formatter.format(json);

I have prepared the following unformatted json string for input/output reference. This is the json template for content-framework, but it's hard to see without any spaces or line breaks.

    {"metadata":{"author":"Kato Shinya","since":"1.0","version":"1.0","creationDate":"2020/06/24","encoding":"UTF-8","description":"test"},"selectionNodes":[{"node":{"conditionId":"0","test1":"test","test2":"test"}},{"node":{"conditionId":"1","test1":"test","test2":"test"}},{"node":{"conditionId":"2","test1":"test","test2":"test"}}],"conditionNodes":[{"node":{"conditionId":"0","exclude":false,"conditions":[{"keyName":"test","operand":"=","value":"0"}]}},{"node":{"conditionId":"1","exclude":false,"conditions":[{"keyName":"test","operand":"=","value":"1"}]}},{"node":{"conditionId":"2","exclude":false,"conditions":[{"keyName":"test","operand":"=","value":"2"}]}}]}

Let's run JSON Formatter with the JSON string of above template as an argument.

JsonFormatter.newInstance().format(json);

The output is as follows.

Note:
Whitespace in the JSON string before formatting is trimmed during the formatting process, so no pre-processing is required.
