NAME

elixir — The Elixir script runner

SYNOPSIS

DESCRIPTION

The program starts the runtime system typically for the execution of one or more scripts. It is similar to iex(1), but elixir exits when the executed script does.

OPTIONS

Note that many of the options mentioned here were borrowed from the Erlang shell, therefore erl(1) can be used as an additional source of information on the options.

-e expression

Evaluates the specified expression.

-r file

Requires the specified file. In other words, the file is checked for existence at the start of elixir.

-S script

Runs the specified script.

-pa directory

Adds the specified directory to the beginning of the code path. If the directory already exists, it will be removed from its old position and put to the beginning.

See also the function Code.prepend_path/1.

-pr file

Does the same thing as -r (see above) but in parallel.

-pz directory

Adds the specified directory to the end of the code path. If the directory already exists, it will be neither removed from its old position nor put to the end.

See also the function Code.append_path/1.

--app application

Starts the specified application and all its dependencies.

--erl parameters

Serves the same purpose as ELIXIR_ERL_OPTIONS (see the ENVIRONMENT section)

--cookie value

Specifies the magic cookie value. If the value isn't specified via the option when the node starts, it will be taken from the file ~/.erlang.cookie (see the FILES section). Distributed nodes can interact with each other only when their magic cookies are equal.

See also the function Node.set_cookie/2.

--detached

Runs the Erlang runtime system detached from the controlling terminal.

--hidden

Starts a hidden node.

Connections between nodes are transitive. For example, if node A is connected to node B, and node B is connected to node C, then node A is connected to node C. The option --hidden allows creating a node which can be connected to another node, escaping redundant connections.

The function Node.list/0 allows getting the list of nodes connected to the target node, however the list won't include hidden nodes. Depending on the input parameter, the function Node.list/1 allows getting the list which contains only hidden nodes (the parameter :hidden) or both hidden and not hidden nodes (the parameter :connected).

--sname name

Gives a node a short name and starts it. Short names take the form of name@host, where host is the name of the target host (hostname(1)) which runs the node. The nodes with short names can interact with each other only in the same local network.

--name name

Gives a node a long name and starts it. Long names take the form of name@host, where host is the IP address of the host which runs the node. In contrast to the nodes with short names, the nodes with long names aren't limited by boundaries of a local network (see above).

--no-halt

Does not halt the Erlang VM after execution.

--

Separates the options passed to the compiler from the options passed to the executed code.

ENVIRONMENT

ELIXIR_ERL_OPTIONS

Allows passing parameters to the Erlang runtime.

FILES

~/.erlang.cookie

Stores the magic cookie value which is used only when it wasn't specified via the option --cookie (see above). If the file doesn't exist when a node starts, it will be created.
