Join Arthur Ulfeldt for an in-depth discussion in this video Conditionals and special forms, part of Learning Clojure.
- [Narrator] We've been talking a lot about symbols,…and what's with all the dashes?…Symbols aren't allowed to start with a number,…because otherwise they'd be read as a number,…but pretty much anything else goes.…You can have all the letters and numbers in a symbol name…as well as a bunch of other useful characters.…More may be added in the future.…What's with all the dashes?…Question mark is a perfectly valid symbol name enclosure.…This wouldn't come up in a lot of other languages…where these symbols are operators that go between things…and have meaning in that position,…but a minus sign between two other letters…has no special meaning within this language,…so it's perfectly available to use it as a name.…
One restriction is slashes.…Slashes split the namespace that a var is defined in…and the name of the var itself.…For instance, we have A123,…perfectly fine symbol name, and IamAname2.…You might be a little confused if you're using these…as your symbol names, but it could come up.…Let's not rule anything out.…
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.
