Specter looks nice. I didn't see any examples in the readme or tests
for working with more deeply nested data structures such as those
discussed in this thread, any pointers?
Here's an example that might be relevant to the original question.
Suppose you have this structure:
(def deep {:a [{:b [{:key 33 :uuid "zyx"}]}
{:b [{:key 4, :uuid "zzz"}]}]})
You want to print out the terminal maps where the `:uuid` is "zyx". You
can do that like this:
user=> (select [:a ALL :b ALL #(= "zyx" (:uuid %))] deep)
[{:key 33, :uuid "zyx"}]
My `structural-typing` library builds a DSL for sort-of type
declarations on top of specter.
https://github.com/marick/structural-typing/ The code is kind of tricksy
in the parts that use Specter, so I don't know if it'll be of much help.
I plan to propose a short (50 pp.) booklet on specter, to be published
on Leanpub. I'll announce it on this mailing list shortly, and use
Leanpub to gauge whether there's enough interest.
