Shallow Diff

A simplified diff/patch solution learning from immutable-diff/patch.

Values are compared with identical? for performace in special scenarios. There's still much room for optimizations in vector diffing.

Usage

[cumulo/shallow-diff "0.1.3"]

(shallow-diff.diff/diff x1 x2)
(shallow-diff.patch/patch x1 operations)

Only hash-map, hash-set, vector are supported. For other types of primitives, it generates set! to replace.

Operations

Format [coord [op arg1 args2]], examples:

[[1   ]  [:add     2  "x"]]

[[:map]  [:remove  1     ]]

For values:

[:set! a-val]

For hash maps:

[:add  a-key a-val]

[:drop a-key      ]

For vectors:

[:insert a-key a-val]

[:remove a-key      ]

[:append a-val      ]

For hash sets:

[:include a-val]

[:exclude a-val]
