Hi, Nicholas.
I would need to see more detail in order to know what is going wrong
in your case. I created a new project myself so that you can see an
example that does work.
First I typed this:
lein new hello
That created a project in the hello directory. I changed in that
directory and edited the file src\hello\core.clj (backslashes because
I am working on Windows, but that isn't a big difference).
cd hello
write src\hello\core.clj
I edited that file to look like this (added an example function).
(ns hello.core)
(defn say-hello [name]
(println "Hello, " name))
After saving that file, I started a REPL to test it out.
lein repl
(use 'hello.core)
(say-hello "Nicholas")
And the REPL responded with:
Hello, Nicholas
nil
It printed out the statement, as I told it to, and showed the return
value of my function: nil.
Note the single-quote in (use 'hello.core) which is a little different
from how the same thing would look as part of the ns macro.
Let me know if you have any more questions about this.
