Clojure namespaces, spec, and why they're confusing
View gist:cc0e7800878c39e4c245fc041c11df4b

To me, "require-and-automatically-visible" is violating the beauty of namespace. But, maybe I felt this way because I don't understand Clojure's registry or how require works.

I thought about this more, and I think I have a better understanding of why this feels strange. Clojure has one thing called "namespaces" which are clojure.lang.Namespace objects created by the ns macro. Functionally speaking they are a storage location which mostly just contain vars and references to vars in other namespaces. They are used for code organization: specifically for organizing vars and occasionally Java classes and interfaces.

Clojure also has a completely different thing called "namespaces" which are prefixes that get attached to keywords and symbols. These can interact with ns namespaces thru the reader in a handful of ways (for instance, ::double-colon keywords and symbols inside backtick forms are resolved according to the current clojure.lang.Namespace) but for the most part should be considered a di

Leiningen Plugins

Leiningen tasks are simply functions named $TASK in a leiningen.$TASK namespace. So writing a Leiningen plugin is just a matter of creating a project that contains such a function, but much of this documentation applies equally to the tasks that ship with Leiningen itself.

Using the plugin is a matter of declaring it in the :plugins entry of the project map. If a plugin is a matter of user convenience rather

Clojure Conj 2017 Talk: Dev Tools as Data

Abstract (5 sentences max)

In the Clojure community we love to say "it's just data", and this enables us to compose things in unique and often-unexpected ways.

One place where that maxim hasn't been thoroughly applied is developer tooling. Representing things like tracers, test runners, and refactoring tools with a unified declarative model allows us to construct powerful meta-tools for various development environments and avoid reinventing the wheel for building interfaces for each editor one at a time.

Let's do some cross-runtime metaprogramming for greater Clojure/editor symbiosis!
