erdos.require-all

A Clojure library designed to look up resources from the classpath.

It can be used to simplify dependency injection. You just put the extra Clojure files on the classpath and the system loads them automatically. For example, have defmethod calls in the custom Clojure files and they automatically take effect without manually require-ing the namespaces.

Usage

First, add the project to your project.clj file: [io.github.erdos/require-all "0.1.2"]

Then need to require the library itself.

(:require [erdos.require-all :refer [require-all]])

Now just call (require-all project.custom.prefix)

Require namespaces

Call (require-all custom-prefix) to require all namespaces with a given prefix.

For example, (require-all myapp.db) may require both myapp.db.postgres and myapp.db.oracle from the classpath.

Lookup resources

The list-all-resources function can be use to get a list of all resource URL objects matching a pattern.

• (list-all-resources :prefix "files/core") will list all files under a path recursively.
• (list-all-resources :suffix ".edn") will list all files with edn extension.
• (list-all-resources :suffix-ci ".edn") is a case-insensitive version of te above.
• (list-all-resources :predicate p) will pass every file to the p predicate function and return only matching items.
