Have there been any developments on the problem of dealing with interactions of libraries and their transitive dependencies? This is always a pain point when upgrading a project with many dependencies to new versions. Maybe the solution is microservices and minimizing the use of libraries altogether in those services, but perhaps there are better ideas out there I'm not aware of.
map could take any collection, but i want to create a binding for the type in the collection
and then say that the function mapped over the collection must take an argument that matches the spec in the binding
@ackerleytng I'm not quite clear what you're asking about -- can you give a code example?
@genekim Perhaps this article is also relevant. https://stuartsierra.com/2015/05/27/clojure-uncaught-exceptions.
such that the spec for map would be something like
(s/fdef map :args (s/cat :f (s/fspec :args :foo) :coll (s/coll-of :foo)))
Well, the issue there is that
map is generic and there really isn't a direct 1:1 mapping between the collection "types" and the function input argument "type" -- you could write a spec for a specific wrapper around
map that was designed to work with a specific type.
clojure.core/map is pretty much impossible to write an accurate spec for I think.
You could define your own
int-map function that only accepted
(s/coll-of int) and therefore required a function whose argument was restricted to
int (well, actually any type that
int can be coerced to -- and that's part of the problem). Do you see what I mean @ackerleytng?
Anyway on the function that I'm speccing, I tried what you suggested with int, and clojure said it couldn't find something that satisfies in 100 tries
Looking for help on what do I need to do or precondition, in order to connect a repl to a running clojure 1.8/1.9 program. Sorry but I do not find https://clojure.org/guides/repl/enhancing_your_repl_workflow#writing-repl-friendly-programs of extreme help... your guidance or reference to a good source, would be much appreciated!
Can an expression that's passed to
-e be saved somewhere in the deps.edn file for later activation ?
I just put a question into the beginner channel regarding a websocket implementation, if anyone has time to look at it.
@noisesmith @hiredman @seancorfield @lloydshark Thanks for all the help, all! Y’all are fantastic!
So, there was a network exception of “could not connect”. But this didn’t explain the
future block not running. I ended rewriting the TCP call with just Java interop, getting rid of
clj-tcp library. All is working now, and much faster now, too. Good enough for me! Thx again!
