`cider-doc` not recognize the right function.

[eval-exec]

I am experiencing an issue with cider-doc in CIDER. Specifically, when I place the cursor on string/join in my Clojure code and invoke the cider-doc command, it seems cider-doc not recgnize the join is from clojure.string/join.

Expected behavior

When I hit K, cider-doc should show clojure.string/join's doc

Actual behavior

cider-doc give me a prompt, I have to type full clojure.string/join to cider-doc's prompt

Steps to reproduce the problem

1. git clone https://github.com/functional-koans/clojure-koans.git
2. open 02_strings.clj file, move cursor to line 28: (= "123" (string/join '(1 2 3)))
3. put cursor to join word. hit K (cider-doc)

Hi @eval-exec, thanks for the report.

I use cider-doc quite often and haven't experienced that.

Are you aware that the ns form where the string alias is declared has to be evaluated (in some or other way) for CIDER to be able to see it?

i.e. since the tool is based on runtime analysis, the alias must exist in the runtime first.

Thank you, I guess there something wrong in my local env. I think it's not important.

Is there some ways to help to debug why cider-doc not aware the join is from clojure.string/join?

[eval-exec]

Wow, I just try cider-doc on join, it works as expected, I don't know why. :smile:
