clj-kondo 2022-05-19

Hi there. A quick suitability check, if you don't mind. The third argument to function foo in our codebase is either a string literal, or a variable which is a string literal, or a value out of a map literal. In other words, if you're reading the source, you can figure out the whole universe of strings passed for this argument; nothing is determined at runtime.
Can clj-kondo be used to enumerate the set of strings passed to foo? At first glance, I see some information about arguments is available, but it doesn't seem like something of this sort would be.

Hi @nick383! Do you mean, implement a custom linter, or just have clj-kondo spit out some information separately from using it as a linter?
Nick McAvoy 2022-05-19T13:48:58.215259Z
The latter - the information is valuable for a purpose different than linting.

I started out looking into tools.analyzer, but wondered if that might be overkill
borkdude 2022-05-19T13:49:27.623469Z
Can you give an example of a string coming from a variable or map?
borkdude 2022-05-19T13:49:43.562139Z
Based on that I might have different options for you

(def bar "bar")
(foo arg1 arg2 bar)(def foos {:baz "baz"})
(foo arg1 arg2 (:baz foos))Nick McAvoy 2022-05-19T13:55:31.261959Z
I'm afraid I must now turn in for the night - currently I'm in South Korea. I'll be back online tomorrow. Thanks so much for your quick response here, and for your help!
borkdude 2022-05-19T13:56:34.554009Z
OK, come back tomorrow and then we'll talk more
borkdude 2022-05-19T13:56:40.381959Z
Just ping me here

Currently clj-kondo doesn't emit any literal values used as arguments, but I was thinking that grasp may help here: https://github.com/borkdude/grasp
