alias(cmd, orig) > Sets an alias of `orig` to `cmd`

appendPath(dir) > Appends `dir` to $PATH

complete(scope, cb) > Registers a completion handler for `scope`.
A `scope` is currently only expected to be `command.<cmd>`,
replacing <cmd> with the name of the command (for example `command.git`).
`cb` must be a function that returns a table of "completion groups."
A completion group is a table with the keys `items` and `type`.
`items` being a table of items and `type` being the display type of
`grid` (the normal file completion display) or `list` (with a description)

cwd() > Returns the current directory of the shell

exec(cmd) > Replaces running hilbish with `cmd`

goro(fn) > Puts `fn` in a goroutine

inputMode(mode) > Sets the input mode for Hilbish's line reader. Accepts either emacs for vim

interval(cb, time) > Runs the `cb` function every `time` milliseconds

multiprompt(str) > Changes the continued line prompt to `str`

prependPath(dir) > Prepends `dir` to $PATH

prompt(str) > Changes the shell prompt to `str`
There are a few verbs that can be used in the prompt text.
These will be formatted and replaced with the appropriate values.
`%d` - Current working directory
`%u` - Name of current user
`%h` - Hostname of device

read(prompt) -> input? > Read input from the user, using Hilbish's line editor/input reader.
This is a separate instance from the one Hilbish actually uses.
Returns `input`, will be nil if ctrl + d is pressed, or an error occurs (which shouldn't happen)

run(cmd) > Runs `cmd` in Hilbish's sh interpreter.

runnerMode(mode) > Sets the execution/runner mode for interactive Hilbish. This determines whether
Hilbish wll try to run input as Lua and/or sh or only do one of either.
Accepted values for mode are hybrid (the default), hybridRev (sh first then Lua),
sh, and lua. It also accepts a function, to which if it is passed one
will call it to execute user input instead.

timeout(cb, time) > Runs the `cb` function after `time` in milliseconds

which(binName) > Searches for an executable called `binName` in the directories of $PATH
