### Install Go JSON Diff Library

Source: https://github.com/yudai/gojsondiff/blob/master/README.md

Use 'go get' to install the gojsondiff library. This is the initial step before using the library in your Go projects.

```sh
go get github.com/yudai/gojsondiff
```

--------------------------------

### Install Go JSON Diff CLI Tool

Source: https://github.com/yudai/gojsondiff/blob/master/README.md

Install the 'jd' command-line tool using 'go get'. This tool allows you to compare JSON files directly from your terminal.

```sh
go get github.com/yudai/gojsondiff/jd
```

--------------------------------

### Install and Use JSON Patch CLI (jp)

Source: https://context7.com/yudai/gojsondiff/llms.txt

Installs the `jp` CLI tool for applying a delta file to a JSON file. Produces the patched JSON output.

```bash
# Install the CLI tool
go get github.com/yudai/gojsondiff/jp

# Apply a delta patch to a JSON file
jp delta.json original.json

# Example: Given original.json:
# {"name": "Alice", "score": 100}
#
# And delta.json:
# {"score": [100, 150], "level": [5]}
#
# Output:
# {
#   "level": 5,
#   "name": "Alice",

```

--------------------------------

### Install and Use JSON Diff CLI (jd)

Source: https://context7.com/yudai/gojsondiff/llms.txt

Installs the `jd` CLI tool for comparing JSON files. Supports ASCII and delta output formats, with options for color and quiet mode.

```bash
# Install the CLI tool
go get github.com/yudai/gojsondiff/jd

# Basic usage - compare two JSON files
jd original.json modified.json

# Output in ASCII format (default):
# {
#   "name": "test",
# -  "value": 10
# +  "value": 20
# +  "new_field": "added"
# }

# Output in delta format (jsondiffpatch compatible)
jd -f delta original.json modified.json

# Output:
# {
#   "new_field": ["added"],
#   "value": [10, 20]
# }

# Enable colored output (for terminals)
jd -c original.json modified.json

# Quiet mode - suppress output if no differences
jd -q original.json modified.json
```

--------------------------------

### JSON Diff Output Example

### DeltaFormatter.FormatAsJson - Get Delta as Go Map

Source: https://context7.com/yudai/gojsondiff/llms.txt

Returns the delta as a Go map instead of a JSON string, useful for further programmatic manipulation. Access delta values by iterating over the returned map.

```go
package main

import (
    "fmt"
    diff "github.com/yudai/gojsondiff"
    "github.com/yudai/gojsondiff/formatter"
)

func main() {
    leftJSON := []byte(`{"status": "pending", "priority": 1}`)
    rightJSON := []byte(`{"status": "complete", "priority": 2}`)

    differ := diff.New()
    d, _ := differ.Compare(leftJSON, rightJSON)

    f := formatter.NewDeltaFormatter()
    deltaMap, _ := f.FormatAsJson(d)

    // Access delta values programmatically
    for key, value := range deltaMap {
        fmt.Printf("Field '%s' changed: %v\n", key, value)
    }
    // Output:
    // Field 'priority' changed: [1 2]
    // Field 'status' changed: [pending complete]
}
```

### Full JSON Diff and Patch Cycle in Go

Source: https://context7.com/yudai/gojsondiff/llms.txt

Demonstrates a complete workflow: comparing two JSON documents, displaying an ASCII diff, generating a storable delta format, loading the delta, and applying the patch to reconstruct the target JSON.

```go
package main

import (
    "encoding/json"
    "fmt"
    diff "github.com/yudai/gojsondiff"
    "github.com/yudai/gojsondiff/formatter"
)

func main() {
    // Step 1: Define source and target JSON
    sourceJSON := []byte(`{
        "version": "1.0",
        "config": {
            "debug": false,
            "timeout": 30,
            "endpoints": ["api.example.com"]
        },
        "features": ["auth", "logging"]
    }`)

    targetJSON := []byte(`{
        "version": "2.0",
        "config": {
            "debug": true,
            "timeout": 60,
            "endpoints": ["api.example.com", "backup.example.com"],
            "retries": 3
        },
        "features": ["auth", "logging", "caching"]
    }`)

    // Step 2: Compare JSON documents
    differ := diff.New()
    d, err := differ.Compare(sourceJSON, targetJSON)
    if err != nil {
        fmt.Printf("Compare error: %s\n", err)
        return
    }

    // Step 3: Display human-readable diff
    var sourceObj map[string]interface{}/
    json.Unmarshal(sourceJSON, &sourceObj)

    asciiFormatter := formatter.NewAsciiFormatter(sourceObj, formatter.AsciiFormatterConfig{
        ShowArrayIndex: true,
        Coloring:       false,
    })
    asciiDiff, _ := asciiFormatter.Format(d)
    fmt.Println("=== ASCII Diff ===")
    fmt.Println(asciiDiff)

    // Step 4: Generate storable delta format
    deltaFormatter := formatter.NewDeltaFormatter()
    deltaJSON, _ := deltaFormatter.Format(d)
    fmt.Println("=== Delta JSON ===")
    fmt.Println(deltaJSON)

    // Step 5: Later, load delta and apply patch
    um := diff.NewUnmarshaller()
    loadedDiff, _ := um.UnmarshalString(deltaJSON)

    // Apply to a fresh copy of source
    var freshSource map[string]interface{} 
    json.Unmarshal(sourceJSON, &freshSource)
    differ.ApplyPatch(freshSource, loadedDiff)

    // Step 6: Verify result matches target
    result, _ := json.MarshalIndent(freshSource, "", "  ")
    fmt.Println("=== Patched Result ===")
    fmt.Println(string(result))
}

```

### Unmarshal String to Diff Object in Go

Source: https://context7.com/yudai/gojsondiff/llms.txt

A convenience method to load a delta directly from a string. Useful for quick patching operations.

```go
package main

import (
    "encoding/json"
    "fmt"
    diff "github.com/yudai/gojsondiff"
)

func main() {
    deltaStr := `{"count": [1, 2], "status": ["inactive", "active"]}`

    original := map[string]interface{}{
        "count":  1,
        "status": "inactive",
    }

    um := diff.NewUnmarshaller()
    d, _ := um.UnmarshalString(deltaStr)

    differ := diff.New()
    differ.ApplyPatch(original, d)

    result, _ := json.MarshalIndent(original, "", "  ")
    fmt.Println(string(result))
    // Output:
    // {
    //   "count": 2,
    //   "status": "active"
    // }
}
```

--------------------------------

### ApplyPatch - Apply Diff to JSON Object

Source: https://context7.com/yudai/gojsondiff/llms.txt

Applies a diff to a JSON object in-place, transforming it to match the target state. This is a destructive operation that modifies the original object.

```go
package main

import (
    "encoding/json"
    "fmt"
    diff "github.com/yudai/gojsondiff"
)

func main() {
    // Original object
    original := map[string]interface{}{
        "name":    "Product A",
        "price":   29.99,
        "inStock": true,
        "tags":    []interface{}{"electronics", "sale"},
    }

    // Target state
    target := map[string]interface{}{
        "name":     "Product A",
        "price":    24.99,  // price changed
        "inStock":  false,  // stock status changed
        "tags":     []interface{}{"electronics", "clearance"}, // tag changed
        "discount": 0.15,   // new field added
    }

    differ := diff.New()
    d := differ.CompareObjects(original, target)

    // Apply the patch to transform original -> target
    differ.ApplyPatch(original, d)

    // Verify the result
    result, _ := json.MarshalIndent(original, "", "  ")
    fmt.Println(string(result))
    // Output:
    // {
    //   "discount": 0.15,
    //   "inStock": false,
    //   "name": "Product A",
    //   "price": 24.99,
    //   "tags": [
    //     "electronics",
    //     "clearance"
    //   ]
    // }
}
```

### DeltaFormatter - jsondiffpatch Compatible Format

Source: https://context7.com/yudai/gojsondiff/llms.txt

Formats a Diff in the delta format compatible with jsondiffpatch. This format is suitable for serialization, storage, and interoperability with JavaScript implementations.

```go
package main

import (
    "fmt"
    diff "github.com/yudai/gojsondiff"
    "github.com/yudai/gojsondiff/formatter"
)

func main() {
    leftJSON := []byte(`{
        "title": "Hello",
        "count": 5,
        "items": ["a", "b", "c"]
    }`)

    rightJSON := []byte(`{
        "title": "Hello World",
        "count": 10,
        "items": ["a", "d", "c"],
        "active": true
    }`)

    differ := diff.New()
    d, _ := differ.Compare(leftJSON, rightJSON)

    // Create delta formatter
    f := formatter.NewDeltaFormatter()
    output, _ := f.Format(d)

    fmt.Println(output)
    // Output:
    // {
    //   "active": [
    //     true
    //   ],
    //   "count": [
    //     5,
    //     10
    //   ],
    //   "items": {
    //     "1": [
    //       "b",
    //       "d"
    //     ],
    //     "_t": "a"
    //   },
    //   "title": [
    //     "Hello",
    //     "Hello World"
    //   ]
    // }
}

    fmt.Printf("Modified: %t\n", d.Modified())
    fmt.Printf("Deltas found: %d\n", len(d.Deltas()))

    // Iterate through deltas
    for _, delta := range d.Deltas() {
        switch delta.(type) {
        case *diff.Modified:
            m := delta.(*diff.Modified)
            fmt.Printf("Modified: %v -> %v\n", m.OldValue, m.NewValue)
        case *diff.Added:
            a := delta.(*diff.Added)
            fmt.Printf("Added: %v\n", a.Value)
        case *diff.Deleted:
            del := delta.(*diff.Deleted)
            fmt.Printf("Deleted: %v\n", del.Value)
        }
    }
}
```

### Response

### Compare Parsed JSON Objects in Go

Source: https://context7.com/yudai/gojsondiff/llms.txt

Compare two already unmarshaled JSON objects (map[string]interface{}). This is efficient when JSON data is already in memory.

```go
package main

import (
    "fmt"
    diff "github.com/yudai/gojsondiff"
)

func main() {
    // Pre-parsed JSON objects
    left := map[string]interface{}{
        "user":   "john",
        "score":  100,
        "active": true,
        "tags":   []interface{}{"admin", "user"},
    }

    right := map[string]interface{}{
        "user":   "john",
        "score":  150,  // modified
        "active": false, // modified
        "tags":   []interface{}{"admin", "moderator"}, // modified
        "email":  "john@example.com", // added
    }

    differ := diff.New()
    d := differ.CompareObjects(left, right)

    fmt.Printf("Modified: %t\n", d.Modified())
    fmt.Printf("Deltas found: %d\n", len(d.Deltas()))

    // Iterate through deltas
    for _, delta := range d.Deltas() {
        switch delta.(type) {
        case *diff.Modified:
            m := delta.(*diff.Modified)
            fmt.Printf("Modified: %v -> %v\n", m.OldValue, m.NewValue)
        case *diff.Added:
            a := delta.(*diff.Added)
            fmt.Printf("Added: %v\n", a.Value)
        case *diff.Deleted:
            del := delta.(*diff.Deleted)
            fmt.Printf("Deleted: %v\n", del.Value)
        }
    }
    // Output:
    // Modified: true
    // Deltas found: 4
    // Modified: true -> false
    // Modified: 100 -> 150
    // Added: john@example.com
}
