# Mendoza, differ for structured documents

Mendoza looks at two structured documents, referred to as _left_ and _right_, and constructs a _patch_ of the differences.

By having the left document and the patch you'll be able to recover the right document.

Mendoza is designed for creating a _minimal_ patch, not necessarily a _readable_ patch.

Example:

```

$ cat left.json

{"name": "Bob Bobson", "age": 30, "skills": ["Go", "Patching", "Playing"]}

$ cat right.json

{"firstName": "Bob Bobson", "age": 30, "skills": ["Diffing", "Go", "Patching"]}

$ dozadiff left.json right.json

[19,1,10,1,14,"firstName",11,2,20,"Diffing",21,0,2,15]

```

**Features / non-features:**

- Lightweight JSON format.

- Flexible format which can accommodate more advanced encodings in the future.

- Differ/patcher available as a Go library (this repo).

- Patcher available as a JavaScript library: [mendoza-js](https://github.com/sanity-io/mendoza-js).

- Efficient handling of renaming of fields.

- Efficient handling of reordering of arrays.

- Not designed to be human readable.

- The patch can only be applied against the exact same version.

**Format**: See [docs/format.adoc](docs/format.adoc)
