os = {}

---Loads an API/library into the global environment
---
---This will load and execute the given file and all exported variables and
---functions will be available under the namespace of the filename
---(e.g.`fileName.functionName`)
---
---🚮 **Deprecated** due to it polluting the global namespace\
---You should instead use `require()` to load libraries/APIs
---@param path string Path to the file to load
---@return boolean success If the API was successfully loaded
------
---[Official Documentation](https://tweaked.cc/module/os.html#v:loadAPI)
function os.loadAPI(path) end

---Unloads an API that was loaded with `os.loadAPI()`
---
---🚮 **Deprecated**, see `os.loadAPI()` for more info
---@param name string The name of the API to unload
------

function os.unloadAPI(name) end

---Pause execution of the current thread and wait for an event to fire
---
---If no event name is provided, it will resume when any event fires
---
---Unlike `os.pullEventRaw()`, this function will stop when it receives a
---`terminate` event and it will print the error "Terminated"
---
---This works by yielding until it receives a vararg list where the first
---element matches the name of the event provided
---@generic T : ccTweaked.os.event
---@async
---@param event? `T` The event to listen for
---@return `T` event The name of the event that fired
---@return any ... Any values returned by the event
---@overload fun(): ccTweaked.os.event, ...
---## Example
---```
---while true do
---    local eventData = { os.pullEvent() }
---    local event = eventData[1]
---
---    if event == "mouse_click" then
---        print("Button", eventData[2], "was clicked at", eventData[3], ",", eventData[4])
---    elseif event == "key" then
---        print("Key code", eventData[2], "was pressed")
---    end
---end
---```
------
---[Official Documentation](https://tweaked.cc/module/os.html#v:pullEvent)
function os.pullEvent(event) end

---Pause execution of the current thread and wait for an event to fire,
---including the terminate event
---
---This behaves nearly the exact same as `os.pullEvent()` except this also
---allows you to handle the `terminate` event, rather than stopping
---
---If no event name is provided, it will resume when any event fires
---
---This works by yielding until it receives a vararg list where the first
---element matches the name of the event provided
---@generic T : ccTweaked.os.event
---@async
---@param event? `T` The event to listen for
---@return `T` event The name of the event that fired
---@return any ... Any values returned by the event
---@overload fun(): ccTweaked.os.event, ...
---## Example
---```
---while true do
---    local event = os.pullEventRaw()
---    if event == "terminate" then
---        print("Caught terminate event!")
---    end
---end

function os.pullEventRaw(event) end

---Pauses execution for the specified number of seconds. An alias for `_G.sleep()`
---@param time number The number of seconds to sleep for, rounded up to the nearest multiple of 0.05
---As it waits for a fixed amount of world ticks, time will automatically be
---rounded up to the nearest multiple of 0.05 seconds. If you are using
---coroutines or the parallel API, it will only pause execution of the current
---thread, not the whole program.
---## Example
---```
---print("Going to sleep for 2 seconds!")
---sleep(2)
---print("Slept for 2 seconds!")
---```
------
---[Official Documentation](https://tweaked.cc/module/os.html#v:sleep)
function os.sleep(time) end

---Get the current CraftOS version. Defined by `bios.lua`
---@return string version CraftOS version (e.g. `CraftOS 1.8`)
------
---[Official Documentation](https://tweaked.cc/module/os.html#v:version)
function os.version() end

---Run a new process
---
---This does not provide access to the `shell` API, for this, you should instead
---use `shell.run()`
---
---If the program cannot be found, or failed to run, it will print the error and
---return false. If you want to handle this more gracefully, use an alternative
---such as `loadfile()`.
---## Example
---```
---local pENV = {}
---local path = "/add.lua"
---local PID = os.run(pENV, path, 2, 2)
---```
------
---[Official Documentation](https://tweaked.cc/module/os.html#v:run)
---@param env table The environment to load the path under. For example, passing `_E` will pass the environment you are currently using.
---@param path string The path to the program to launch
---@param ... any Additional arguments to pass to the program
function os.run(env, path, ...) end

---Adds an event to the event queue that can later be listened to with `os.pullEvent()`
---@param name ccTweaked.os.event The name of the event to queue
---@param ... any The parameters of the event that can be read later
---@triggers `any`
------

function os.queueEvent(name, ...) end

---Start a timer that will fire a `timer` event when it reaches the specified
---number of seconds.
---
---As this waits for a fixed amount of world ticks, `seconds` will be rounded up
---to the nearest multiple of 0.05 seconds
---@param seconds number The number of seconds until the timer fires
---@return integer ID The ID of the new timer
---@throws If `seconds` is below zero
---@triggers `timer`
------

---Set an alarm that will fire an `alarm` event at the requested game-time.
---@param time number The game-time to fire the event at (0.0 - 24.0)
---@return integer ID The ID of the new alarm
---@throws if the `time` is out of range
---@triggers `alarm`
------
---[Official Documentation](https://tweaked.cc/module/os.html#v:setAlarm)
