defmodule <%= @mod_name %> do
  @moduledoc """
  Provides precompiled svgs for <%= @mod_name %>.

  ## Usage

  Function names are based on the svg filename, for example:
  <% f_name = Enum.random(@svgs) |> elem(0) %>

  ```heex
    <<%= @mod_name%>.<%= f_name %> />
  ```

  You can also pass arbitrary HTML attributes to the components:
   ```heex
  <<%= @mod_name%>.<%= f_name %> class="w-2 h-2" />
  ```

  use Phoenix.Component

  defp svg(assigns) do
    assigns =
      assign(
        assigns, :computed_rest, Map.merge(assigns.rest, Enum.into(assigns.svg_attrs, %{}))
      )

    ~H"""
    <svg {@computed_rest}>
      <%%= {:safe, @paths[:default]} %>
    </svg>
    """
  end


  <%= for svg <- @svgs, {func, [{"svg", svg_attrs, els}]} = svg do %>
  @doc """
  Renders the `<%= func %>` svg.

  By default, it maintains the svg attributes loaded from file.
  You may also pass arbitrary HTML attributes to be applied to the svg tag.

  ## Examples

  ```heex
  <<%= @mod_name %>.<%= func %> />
  <<%= @mod_name %>.<%= func %> class="w-4 h-4" />
  ```
