Clojure and EDN diff tool
Oct 8, 2020 • Yehonathan Sharvit
Compare recursively two Clojure data structures a and b.
Comparison is updated as you type…
xxxxxxxxxx
(def a {:only-in-a 1:both-in-a-and-b 3})
the evaluation will appear here (soon)...
xxxxxxxxxx
(def b {:only-in-b 2:both-in-a-and-b 3})
xxxxxxxxxx
the evaluation will appear here (soon)...
Full comparison:
xxxxxxxxxx
(def full-comparison (clojure.data/diff a b))
xxxxxxxxxx
the evaluation will appear here (soon)...
Things only in a:
xxxxxxxxxx
(first full-comparison)
xxxxxxxxxx
the evaluation will appear here (soon)...
Things only in b:
xxxxxxxxxx
(second full-comparison)
xxxxxxxxxx
the evaluation will appear here (soon)...
Things in both a and b:
xxxxxxxxxx
(last full-comparison)
xxxxxxxxxx
the evaluation will appear here (soon)...
Comparison rules:
- For equal
aandb, return[nil nil a]. - Maps are subdiffed where keys match and values differ.
- Sets are never subdiffed.
- All sequential things are treated as associative collections by their indexes, with results returned as vectors.
- Everything else (including strings!) is treated as an atom and compared for equality.
