err - engine really rong

Intro

Some code I reuse for games. There is possibly some emphasis on iterative development, but it's still young and convoluted.

Example

Currently an Opengl window can be opened with this:

(defun initialize ())
(defun handle-input ())
(defun render ())
(defun update ())
(defun cleanup ())

(defun example ()
  (err:err-run "insert-title"
               :init-code (initialize)
               :input-code (handle-input)
               :render-code (render)
               :update-code (update)
               :cleanup-code (cleanup)))

See examples folder for some basic projects.

Installation

err is known to work with SBCL and Clozure on Linux and Windows (get libraries with win-builds).

1. Get Common Lisp, remember to install quicklisp.

2. Get dependencies, either through quicklisp or from their repositories.

• alexandria
• iterate
• cl-fad
• cl-glfw3
• cl-opengl
• glkit
• cl-freetype2
• fset
• defenum
• ironclad

Not in quicklisp (get from their repositories): * cl-soil

3. clone this project into the quicklisp/local-projects/ (by default in your user home folder):

$ cd ~/quickload/local-projects/

$ git clone https://github.com/hahahahaman/err

4. add ASD project file

Add the relative path of the asd file into system-index.txt (also in the local-projects folder):

err/err.asd

err/err-examples.asd

OR

launch Common Lisp, add project to asdf, and load err:

$ sbcl

* (push #p"/path/to/err" asdf:*central-registry*)

* (ql:quickload :err)
