It is based on the Apache 2.0 licensed library from Flipkart, zjsonpatch.
This project is a fork of KJsonPatch (with the latest commit referenced).

This code has been modified from the original library in the following ways:

• Ported from Java to Kotlin
• Changed package names
• Substituted Gson dependency with kotlinx.serialization.json
• Added extensions for convenient usage of kotlinx.serialization.json

Add the dependency to your app module’s build.gradle file:

repositories {
    mavenCentral()
}

dependencies {
    // e.g., implementation("io.github.reidsync:kotlin-json-patch:1.0.0")
    implementation("io.github.reidsync:kotlin-json-patch:${kotliln_json_patch_version}")
}

Check the kotlin-json-patch versions
latest version :

You can add the dependency to sourceSets.commonMain.dependecies for your Kotlin Multiplatform project.

kotlin {
    sourceSets {
        commonMain.dependencies {
            //put your multiplatform dependencies here
            implementation("io.github.reidsync:kotlin-json-patch:${kotliln_json_patch_version}")
        }
    }
}

The variables source, target, and patch below must be asserted as valid JsonElement objects.

val diff: JsonArray = JsonDiff.asJson(source: JsonElement, target: JsonElement)

or

val diff: JsonElement = source.generatePatch(with: target)

val result: JsonElement = JsonPatch.apply(patch: JsonElement, source: JsonElement)

or

val result: JsonElement = source.apply(patch: patch)

This operation is performed on a clone of the source object.

These changes mostly involve porting from Java to Kotlin to transform it into a pure Kotlin library that can be imported into Kotlin Multiplatform. If you have any specific preferences or further adjustments, feel free to let me know!
