lein-filegen

A Leiningen plugin that generates files based on the instructions in project.clj.

This is useful for generating artefacts outside of src such as configuration files etc.

Usage

Use this for project-level plugins:

Put [lein-filegen "0.0.1"] into the :plugins vector of your project.clj.

Configuration

To use lein-filegen you'll need to add a :filegen vector into your project.clj.

The filegen vector contains a hash which prescribes how to generate a file. It needs to know:

• :target file to generate
• :data from which to generate the file
• :template-fn to transform the data into the string which will be written to the file
• :requires, an optional argument to require any namespaces for the template-fn to work

In full it looks something like this:

:filegen [{:data {:environment ~(System/getenv "ENVIRONMENT")
                  :database-url ~(System/getenv "DATABASE_URL")
                  :version ~(fn [p] (:version p))}
             :requires '[clojure.data.json :refer [write-str]]
             :template-fn ~(fn [project data] (write-str data))
             :target "resources/configuration/config.json"}]

The above takes the data and converts it to a json file.

As it's a vector filegen can take multiple hash instructions for different files.

Run

$ lein filegen
