every "file" on the classpath should be accessible as resource. You can just slurp it before calling load . But clojure code is a vague term, it might be a compiled class or real source file.

if load can find them on the classpath, then so can you with whatever mechanism you like.

user=> (doc find-ns)
-------------------------
clojure.core/find-ns
([sym])
  Returns the namespace named by the symbol or nil if it doesn't exist.
nil
user=> (find-ns 'clojure.core.reducers)
nil
user=> (subs (slurp ( "clojure/core/reducers.clj")) 0 20)
";   Copyright (c) Ri"

here i demonstrate that i haven’t loaded the reducers namespace but it’s on the classpath so i can find it by many mechanisms

cool, thank you

With emacs/cider, you can cider-open-classpath-entry which might be similar to what you are after?

that’s your issue. the -X will pass a single map to your function. if main/hello accepts no arguments, you will get a “wrong number of args (1) passed to main/hello”

I had another function with 2 parameters, when I tried to call it I also got the same error. Any idea how to properly call it ? Here's how I did it : clj -X main/get-contracts 100 200

-X expects to call a function that takes one associative argument

the error isn't the same

(i’m trying to find documentation about this but surprisingly not finding it in the guide or reference on http://clojure.org)

theres an example here https://clojure.org/guides/deps_and_cli clojure -X:repl-server :port 51234

in the first case it says (1) because 0 args are being passed to a function that expects 1, in the second case it will say something like (2) because 1 arg is being passed to a function that expects 2

@U0NCTKEV8 yea exactly

https://clojure.org/guides/deps_and_cli#_using_a_main

no, I am confusing things

the first says 1 argument passed (expected 0) The other says 1 argument passed (Expected 2)

I added a parameter to hello and it works with clj -X main/hello

oh, well I am just confusing myself then, anyway -X always passes a single argument, which is a possibly empty map

If my function takes 2 arguments how can I do ? I cant find anything in the doc 😕

you can't with X

you can parameterize the map passed clojure -X:my-fn :foo 1 :bar 2

the way -Xfoo 1 2 is handled is a map {1 2} is what gets passed as the argument

so if a function takes more than 1 argument you cannot call it with -X

ahhh so I have to change my function so it takes a map i guess

if you want to use it with -X

I know -M is for the main, is there any other flag that could help me in my case ?

you can use -M to call whatever function you want

ah, but I guess -m only supports a namespace with a -main function, which I always forget, so you would have to use -e or something, which will make the args stuff not as nice

yea thats what I meant with -M is for the main lol

thanks guys

-M is for the clojure.main launcher

-m is a flag for clojure.main

so properly -M -m whatever

there is no CLI option to invoke an arbitrary function. you can: • clj -M -m namespace-with-main to invoke a namespace that has a -main [& args] function • clj -X ns/f to invoke a function that takes a map of args • clj -M file.clj to run all top-level expressions in file.clj

If you use namespaced keywords for your atom's attributes you should be able to see usages, but it will make the code more verbose. Otherwise it just comes to structuring the code, keep events that modifies the same data close together, etc.
