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.
- 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.
