;;; Commentary:
;; Tests that my termios function works, at least somewhat.
;; Note that this actually modifies the terminal it's run on, and might fail
;; if the terminal doesn't support the wanted modes. See termios(3).
;; It might also leave the terminal in a broken state if exited prematurely.
;;; Code:
(define-module (test termios)
:use-module (srfi srfi-64)
:use-module (srfi srfi-88)
:use-module ((hnh util) :select (set!))
:use-module ((vulgar termios)
:select (make-termios
copy-termios
lflag
tcgetattr!
tcsetattr!
ECHO
ICANON))
:use-module ((srfi srfi-60)
:select ((bitwise-ior . ||)
(bitwise-not . ~)
(bitwise-and . &))))
