Created base.json and override.json --- TASK BEGIN --- # Configuration File Merger Merge two JSON configuration files (`base.json` and `override.json`) into `merged.json`. ## Merge Rules 1. **Objects**: Deep merge recursively - Keep all keys from base that aren't in override - Override values replace base values for matching keys - Nested objects merge recursively at all levels 2. **Arrays**: Complete replacement (not concatenation) - Override arrays completely replace base arrays - Array order should be preserved exactly as in override 3. **Primitives**: Override wins - Strings, numbers, booleans from override replace base - Type changes are allowed (e.g., number ��� string) 4. **Null handling**: `null` in override REMOVES the key entirely - Works recursively in nested objects - Example: `{"a": {"b": null}}` removes key `b` from nested object `a` - Top-level null values remove top-level keys ## Example Base: `{"server": {"port": 3000, "host": "localhost"}, "remove": "me"}` Override: `{"server": {"port": 8080}, "remove": null}` Result: `{"server": {"port": 8080, "host": "localhost"}}` Note: `server.host` preserved (deep merge), `remove` deleted (null), `server.port` overridden PS: You are currently working in an automated system and cannot ask any question or have back and forth with an user. --- TASK END --- INFO 2025-12-26T16:49:39 +747ms

perform the JSON configuration file merge according to the specified rules. First, I will create the three required files: `base.json`, `override.json`, and the script `merger.py`. I will use your provided example data for `base.json` and `override.json`. My plan is: 1. Create `base.json` with example content. 2. Create `override.json` with example content. 3. Write `merger.py` to implement the deep merge logic. 4. Run `merger.py` to generate `merged.json`. 5. Read the contents of `merged.json` to verify the solution. ### Step 1 & 2: Create JSON files I will create `base.json` and `override.json` using the example data.

Since these are not system-modifying commands beyond file creation in the current directory, I will skip the explanation.

`merger.py`:** 1. Define a recursive `deep_merge` function. 2. Iterate over the override dictionary. 3. If a value in override is `None` (null), delete the corresponding key in base. 4. If the value is a dictionary, merge recursively. 5. If the value is a list (array), fully replace the corresponding value in base. 6. For primitives, override the base value. 7. Load and save the files using `json` module. I will use the `write` tool to create the file. Since I have not read this file, the write will be allowed.

object):** `host` is preserved, `port` is overridden. 2. **Array Replacement (server.services):** The array `["api", "web"]` is completely replaced by `["new-web", "new-api"]`. 3. **Primitives Override (settings):** The number `100` is replaced by the string `"new_setting"`. 4. **Null Handling (database and remove):** Both `database` (object) and `remove` (primitive) were removed because they were set to `null` in `override.json`. 5. **New Key:** `another_key` was added. 6. **Unmodified Array:** `array_replace_example` was preserved as it was not present in the override file. The `merger.py` script successfully implemented the configuration merger.
