I’ve been doing some monorepo spelunking and am calling clojure.tools.cli.api/tree programmatically to get the dependency hierarchy. To get the result as data:

(-> (deps/tree {:project deps-map, 
                :format :edn})
    (with-out-str)
    (edn/read-string))

Works a treat. That said, the round-tripping from pprint within cli/tree and re-parsing makes me suspect I’m doing it wrong.

I could call clojure.tools.deps.alpha.tree/trace->tree but there’s some nice setup within cli/tree that I’d rather not duplicate https://github.com/clojure/tools.deps.alpha/blob/master/src/main/clojure/clojure/tools/cli/api.clj#L151-L156

I suspect this information is in the basis as well. My likely-too-brief and naïve inspection of the basis thinks shows that it’s already flattened and inverted from what’s returned by cli/tree (listing parents rather than children).

There is not sufficient information in the rest of the basis to construct the “tree” (it's not really a tree)
