This is a repository with all of the functions me (xgaarocha) and my friend (bravejuliano) created and are useful outside of our in-development Operational System. Bear in mind we have a "If it works it's good for now" policy currently, which means we will make it work first, finish the OS then optimize things. We don't guarantee 100% security and stability of our functions.

Delay

Function: Creates an interval with seconds/minutes/hours and can show a countdown.

Usage: interval(s, m, h, tleft) (Eg.: interval (0, 2, 0, "yes") > Shows a countdown of 2 minutes)

Parameters: s,m,h = seconds, minutes, hours / rleft = "yes" enables coutdown, leave blank or "no" to disable it.

Spoiler

function delay(s, m, h, tleft)
-- Define parameters and vars
s = s or 1
m = m or 0
h = h or 0
tleft = tleft or "no"
delay = s + m*60 + h*3600

-- Check for negative numbers
if s < 0 then error("Delay time can only be positive") end
if m < 0 then error("Delay time can only be positive") end
if h < 0 then error("Delay time can only be positive") end
if s+m+h == 0 then error("Delay time can only be positive") end
-- Delay without time left
if tleft == "no" then
sleep(delay)
end
-- Delay with time left
if tleft == "yes" then
while delay ~= 0 do
h = math.floor(delay/3600)
m = math.floor(delay/60 - h*60)
s = math.floor(delay -h*3600 -m*60)
print("[", h, ":", m, ":", s, "]")
sleep(1)
delay = delay - 1
term.clear()
term.setCursorPos( 1, 1 )
end
end
end

Loading/Progress Bar
Function: Creates a bar that fills-up in a determined amount of time.

Usage: loadbar(s, char, size) (Eg.: loadbar(10, #, 10, "yes") > Creates a bar that fills up in 10 seconds with 10 #)
Parameters: s = duration in seconds / char = the character the bar is made of / size = bar's size, leave blank for auto

Spoiler

function loadbar(s, char, size)
	-- Define parameters
	s = s or 5
		size = size or swidth
	char = char or "#"
	local xpos,ypos = term.getCursorPos()
	local delay = s/size
	local start = 1
	while start < size  do
	term.setCursorPos(start, ypos)
	print (char)
	sleep(delay)
	start = start + 1
	end
end

nice coding xgaarocha. well done.

one tip:

if s<0 then error("something")

can be rewritten as:

assert(s>=0,"something")

[TheNotch3000]

looks nice! I will surely use this. />

[Bladedemon70]

Sorry for the noob question but for the loadbar do you replace all the paramater in the () or which ones do you need to replace

Nevermind i got it
