2023-04-23 Hiding in the clear

Have you ever needed to bang out a post, but didn't want an other who in all other ways significant asking gobs of question?

Meet a little Lua script I wrote and named "eat", because it eats typed characters - by which I mean they never appear on the screen, screen remains blank, sure you might have to explain the sound of mad typing if you're good at it, but other than that you've no "'splainin'" to do:

#! /usr/bin/env lua
os.execute('clear')
os.execute("stty -icanon") -- put TTY in raw mode
local s = ''
while true do
	local c = io.read(1)
	if c == '\004' then
		break
	else
		s = s .. c
		os.execute('clear')
	end
end
os.execute("stty icanon") -- at end of program, put TTY back to normal mode
local handle = io.open('z', 'w')
handle:write(s)
handle:close()

Run it, type away, eventually hit ctrl-d to end the session. The text winds up in a file named 'z' in the current directory.

Simple. Safe. Gulorious.....
