Clojurians Log v2

Put together a small debug macro for my current project. It does the job, but are there any standard libraries or better patterns I should be looking at instead? https://github.com/amiorin/big-config/blob/1a334791c395aefc1fa040c744c2ee614cbdc749/src/clj/big_config/utils.clj#L65
I'd say yes. At a quick glance, your macro doesn't support nesting, for example. Personally, I much prefer to use "raw" taps with something like Portal. Getting tapped values back to the REPL is trivial. Tap hierarchy and scope are easy to maintain - well, at least in non-concurrent contexts. Just add some specific structure to the tapped values. In concurrent contexts, not much harder - just add the thread name to the tapped structure.
@alberto.miorin shameless plug here but https://www.flow-storm.org/ is a project that takes that idea much further.
@alberto.miorin not sure if it is a fit for your current project, but https://github.com/paintparty/fireworks offers the featureful debugging macro, ? , which is focused on themeable printing in the context of a hot-reloaded workflow. There is also a ?> macro for raw tapping that you could use in conjunction with something like Portal. Some basic https://github.com/paintparty/fireworks?tab=readme-ov-file#editor-integrations were recently added. There is also a section of the readme with https://github.com/paintparty/fireworks?tab=readme-ov-file#alternatives--prior-art that may be of interest.

requiring-resolve returns a stale version of the function. The fn is ok, the symbol is stale, why? I have restarted the JVM and executed cider-load-buffer. Is there a dot directory that I should delete? What is the correct procedure to avoid this problem?
(defn- resolve-fn [kw opts]
(let [f (get opts kw)]
(cond
(nil? f) (throw (ex-info (format "`%s` not defined" kw) opts))
(fn? f) f
(symbol? f) (requiring-resolve f)
:else (throw (ex-info (format "Value for `%s` is neither a function nor a symbol" kw) opts))))) What exactly do you do to reproduce it? How do you determine that it's stale?
I've seen this with aot classes being left around. Those are consulted before source files iirc
FWIW the logic is
lastModified(classURL, classfile) > lastModified(cljURL, scriptfile)
