Looks useful for all of us with deps.edn projects. Thank you!

And what a great, illustrative, problem statement BTW!

Added deps cli example. Just make some changes in your deps.edn then run:

clj -Sdeps '{:deps {io.github.namenu/deps-diff {:git/tag "v1.1" :git/sha "c1e0a84"}}}' \
    -X namenu.deps-diff/diff \
    :base '"HEAD"' \
    :target '"deps.edn"' \
    :format :cli

Thanks for the advice. My initial thought was generating deps.lock. However, if the alias is n, the calculation grows to 2^n, which is a disadvantage. I have no idea how to workaround this

well... u should be using some off the shelf diffing solution, instead of trying to roll your own. there are a few to choose from: 1. https://clojuredocs.org/clojure.data/diff 2. https://github.com/lambdaisland/deep-diff2 3. https://github.com/juji-io/editscript also, i would just look into how does clojure -X:deps tree work and call it directly from your tool, to avoid dealing with temporary files.

uh no, diffing algorithm is okay. (by using simple set algebra) Regarding clojure -X:deps tree, you probably want to specify :aliases argument either. you want to compare only for :dev alias, or :test alias or for [:dev :test] alias, etc. The library can't make any assumptions about this, so it has to compute every combination.

I just didn't want to go that path..

Someone asked on reddit if it worked with figwheel main. Looks like it does! Just tried the https://github.com/bhauman/flappy-bird-demo-new , recorded a little bit while the bird was flying and looks like it works fine. Here you can see how I configured it : https://github.com/jpmonettas/flappy-bird-demo-new/commit/108d4c223288ea14033180fe424aff0f6146a78b

There is also this new functionality on the latest FlowStorm https://jpmonettas.github.io/flow-storm-debugger/user_guide.html#_limiting_recording that helps with high frequency functions, which is pretty common in ClojureScript when you have animations or code that fires on something like mouse moves.
