NAME

     iex — The Elixir shell

SYNOPSIS

     iex [OPTIONS]

DESCRIPTION

     The interactive shell is used for evaluation, debugging and introspection of the Elixir
     runtime system. It is also possible to use the program for testing the work of small pieces
     of code escaping the stage of saving the code in a file.

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.

     -h, --help
             Displays the help message to the standard error (stderr) and exits.

     -v, --version
             Displays the Elixir version to the standard output (stdout) and exits.

     -e, --eval expression
             Evaluates the specified expression (see the --rpc-eval option).

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

     -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.

     --boot file
             Specifies the name of the boot file, file.boot, which is used to start the system.
             Unless File contains an absolute path, the system searches for file.boot in the
             current and $ROOT/bin directories.

             Defaults to $ROOT/bin/start.boot.

             The option is equivalent to Erlang's -boot.

     --boot-var var dir
             If the boot script contains a path variable var other than $ROOT, this variable is
             expanded to dir.  Used when applications are installed in another directory than
             $ROOT/lib.

             The option is equivalent to Erlang's -boot_var.

             See also the function :systools.make_script/1,2 in SASL.

     --erl parameters
             Serves the same purpose as ELIXIR_ERL_OPTIONS (see the ENVIRONMENT section)

     --erl-config file
             Specifies the name of a configuration file, file.config, which is used to configure
             applications. Note that the configuration file must be written in Erlang.

             The option is equivalent to Erlang's -config.

     --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.

     --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).

     --logger-otp-reports val
             Enables or disables OTP reporting (val can be either true or false).

     --logger-sasl-reports val
             Enables or disables SASL reporting (val can be either true or false).

     --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).

     --pipe-to pipedir logdir
             Starts the Erlang VM as a named pipedir and logdir (only for Unix-like operating
             systems).

     --rpc-eval node expression
             Evaluates the specified expression on the specified node (see the --eval option).

     --vm-args file
             Reads the command-line arguments from file and passes them to the Erlang VM.

             The option is equivalent to Erlang's -args_file.

     --werl  Uses Erlang's Windows shell GUI (only for Windows).

     --dot-iex file
             Loads the specified file instead of .iex.exs (see the FILES section).

     --remsh node
             Connects to the specified node which was started with the --sname or --name options
             (see above).

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

NOTES

     The following options can be given more than once: --boot-var, --erl-config, --eval,
     --rpc-eval.

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.

     .iex.exs
             After iex starts, it seeks the file .iex.exs and, in a case of success, executes the
             code from the file in the context of the shell. At first the search starts in the
             current working directory, then, if necessary, it continues in the home directory.
