Input Event Codes

This little library is a port of all constants found in input-event-codes.h, an event code header file found on both Linux and FreeBSD.

(require :input-event-codes)

;; Print all constants and their values
(do-external-symbols (sym :input-event-codes)
  (format t "~S = ~D" sym (symbol-value sym)))

;; Convoluted example...
(defun handle-button-event (code pressed-p)
  (when (= btn input-event-codes:+btn-left+)
    ...))

There is currently only support for Linux and FreeBSD. The library uses trivial-features to conditionally load the appropriate constant set. If this or a similar header is found in other operating systems, please let me know and I will add them. :)

Native Documentation

The Linux Kernel docs provides an outline over all the event code constants.
