This is the command iex that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
iex — The Elixir shell
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.
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.
Evaluates the specified expression.
Requires the specified file. In other words, the file is checked for existence at
the start of iex.
Runs the specified script.
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.
Does the same thing as -r (see above) but in parallel.
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.
Starts the specified application and all its dependencies.
Serves the same purpose as ELIXIR_ERL_OPTIONS (see the ENVIRONMENT section)
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.
Runs the Erlang runtime system detached from the controlling terminal.
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
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.
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).
Loads the specified file instead of .iex.exs (see the FILES section).
Connects to the specified node which was started with the --sname or --name options
-- Separates the options passed to the compiler from the options passed to the executed
Allows passing parameters to the Erlang runtime.
