Hi!
If I understand correctly... consider something like the following:
(let [log (d/log (db/conn))
my-tx 123456789123456]
(->> (d/tx-range log my-tx (inc my-tx))
seq
pprint))
You get a bunch of datoms and transaction ID.
You can access a datom's fields with: :e :a :v :tx :added.
At first, the datoms look depressing because attributes look like 74 instead
of :mouse/name. So use(d/ident db 74) to get :mouse/name. (You might like
to make a little util which turns these datoms into a nice map or record.
Records are nice because they seem to print fields in the :e :a :v :tx
:added order you declare.)
FWIW, you may see two datoms where the entities are the same, but :added is
different. That's because you changed something; the entity's old value was
retracted and the new value was added.
Hope this helps,
Tj
