This library provides some macros for extracting keyword args from lists. It can be helpful in situations where normal cl-defun arglist handling is not enough.

Macros

• extract-keyword-arg : Remove KEY & following item from list referenced by LSTSYM, and return item.
• extract-keyword-bindings : Extract KEYS and corresponding values from ARGS, and return in let-style bindings list.
• extract-first-keyword-arg : Remove & return first key & following item from list referenced by LSTSYM.
• loop-over-keyword-args : Loop over the keyword args in list LST, evaluating BODY forms each time.

Installation

Put keyword-arg-macros.el in a directory in your load-path, e.g. ~/.emacs.d/ You can add a directory to your load-path with the following line in ~/.emacs (add-to-list ‘load-path (expand-file-name “~/elisp”)) where ~/elisp is the directory you want to add (you don’t need to do this for ~/.emacs.d - it’s added by default).

Add the following to your ~/.emacs startup file.

(require ‘keyword-arg-macros)
