Clojurians Log v2

I think I'm confused.

filterer navigates to a sequence of all "locations" in the sequence matching the predicate

with index 0 being the first location, index 1 being the second, and so on

transformations to the sequence navigated to by filterer can only affect those locations

increasing the size of the sequence just causes indexes past the last location to be ignored

there's a special case for when you reduce the size of the sequence to set the removed locations to NONE

Hmmmm, OK. So, there is no 'obvious / out of the box' way to insert? Using a combo of index-vals and before-index works fine, is that the 'right way' to do this?

zipper navigators are good for this use case

com.rpl.specter.zipper

user=> (setval [z/VECTOR-ZIP (z/find-first #(= "b" %)) z/INNER-LEFT] [77] ["a" "b" "c"])
["a" 77 "b" "c"]

😮

Presumably that is much more efficient as well?

unclear

zippers do have overhead

the com.rpl.specter.zipper namespace is not totally fleshed out, so there are other navigators that could be added to make it more efficient

such as the zipper equivalent of before-index instead of doing INNER-LEFT

Hi All, i have a question. Why when use this symbol ’[?e :a true] inside a select nav its resolve to [?e :a G__161070]? ex: (select [ALL (pred #(= (log/spy %) (log/spy '[?e true])))] ['[?e true]]) return [].
