Join Arthur Ulfeldt for an in-depth discussion in this video Use REPLs to execute code, part of Up and Running with Clojure.
- [Narrator] Now let's take some time to take a look…at what that REPL we've been using actually is.…REPL, that's a nice word, four letters long.…R stands for Read.…That's where it takes the characters you've typed…with your keyboard, and translates them…into data structures.…If you typed in the characters for a list,…it translates it to a list.…If you typed in the characters for an array,…it translates it to an array.…The same goes for sets and hashmaps, et cetera.…The step after that, the E, is the Evaluate.…
Takes that data structure you typed in the previous step,…and translates it into one other data structure,…essentially by running it.…Most often this is simply a function call.…Once it's run your code or evaluated your form,…it Prints it out to the screen in the format…used by the reader so that we can finish off our REPL…with Loop, and loop right back up to the Read…for the next statement.…And a little bit on the language itself…and the compiler we're talking about here.…
And Clojure is a fully compiled language.…
Arthur Ulfeldt covers the Leiningen build tool and setting up Clojure to work with the IntelliJ IDEA dev environment. He then reviews the basics of the syntax, including functions, expressions, values, macros, strings, and conditionals. He shows how to structure, compile, and deploy Clojure projects in Leiningen, and pull from Clojure's core library. In the final chapters, Arthur explores references and namespaces and points to resources to learn more about Clojure.
