Connect the session to an already running node
|
|
and evaluate code in the context of that node.
|
|
Thanks to this approach you can work with
|
|
an arbitrary Elixir runtime.
|
|
Make sure to give the node a name, for example:
|
|
</p>
|
|
<div class="text-gray-700 markdown">
|
|
<%= if Livebook.Config.shortnames? do %>
|
|
<pre><code>iex --sname test</code></pre>
|
|
<% else %>
|
|
<pre><code>iex --name test@127.0.0.1</code></pre>
|
|
<% end %>
|
|
</div>
|
|
<p class="text-gray-700">
|
|
Then enter the name of the node below:
|
|
</p>
|
|
<%= f = form_for :node, "#", phx_submit: "init" %>
|
|
<%= text_input f, :name, value: @name, class: "input",
|
|
placeholder: if(Livebook.Config.shortnames?, do: "test", else: "test@127.0.0.1") %>
|

<%= submit "Connect", class: "mt-3 button button-blue" %>
