Functions in the global environment, defined in `bios.lua`. This does not
include standard Lua functions.

--[[- Pauses execution for the specified number of seconds.

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|parallel API}, it will only pause execution of the current
thread, not the whole program.

:::tip
Because sleep internally uses timers, it is a function that yields. This means
that you can use it to prevent "Too long without yielding" errors. However, as
the minimum sleep time is 0.05 seconds, it will slow your program down.
:::

:::caution
Internally, this function queues and waits for a timer event (using
@{os.startTimer}), however it does not listen for any other events. This means
that any event that occurs while sleeping will be entirely discarded. If you
need to receive events while sleeping, consider using @{os.startTimer|timers},
or the @{parallel|parallel API}.
:::

@tparam number time The number of seconds to sleep for, rounded up to the
nearest multiple of 0.05.

@see os.startTimer
@usage Sleep for three seconds.

--[[- Reads user input from the terminal. This automatically handles arrow keys,
pasting, character replacement, history scrollback, auto-completion, and
default values.

@tparam[opt] string replaceChar A character to replace each typed character with.
This can be used for hiding passwords, for example.
@tparam[opt] table history A table holding history items that can be scrolled
back to with the up/down arrow keys. The oldest item is at index 1, while the
newest item is at the highest index.
@tparam[opt] function(partial: string):({ string... }|nil) completeFn A function
to be used for completion. This function should take the partial text typed so
far, and returns a list of possible completion options.
@tparam[opt] string default Default text which should already be entered into
the prompt.

@treturn string The text typed in.

@see cc.completion For functions to help with completion.
@usage Read a string and echo it back to the user

    write("> ")
    local msg = read()
    print(msg)

@usage Prompt a user for a password.

    while true do
      write("Password> ")
      local pwd = read("*")
      if pwd == "let me in" then break end
      print("Incorrect password, try again.")

@usage A complete example with completion, history and a default value.

    local history = { "potato", "orange", "apple" }
    local choices = { "apple", "orange", "banana", "strawberry" }

@changed 1.80pr1 Added `default` parameter.
