##  Mix task to Transform EEx templates in the context of the `Extractly` module.

  This tool serves two purposes.

  1. A simple CLI to basicly `EEx.eval_file/2`

  1. Access to the `Extractly` module (available as binding `xtra` too)

  The `Extractly` module gives easy access to Elixir metainformation of the application using
  the `extractly` package, notably, _module_  and _function_ documentation.

  This is BTW the raison d'être of this package, simple creation of a `README.md` file with very simple
  access to the projects hex documentation.

  Thusly hexdoc and Github will always be synchronized.

  To see that in action just look at the [`README.md.eex`](README.md.eex) file of this package and compare
  with what you are reading here.


  Example Template:

      Some text
      <%= xtra.functiondoc("M.shiny_function/2") %>
      <%= xtra.moduledoc("String") %>

      More text


### Usage:

    mix xtra [options]... [template]

#### Options:

    --help     Prints short help information to stdout and exits.
    --version  Prints the current version to stdout and exits.
    --verbose  Prints additional output to stderr

    --output filename
              The name of the file the rendered template is written to, defaults to the templates'
              name, without the suffix `.eex`

#### Argument:

    template, filename of the `EEx` template to use, defaults to `"README.md.eex"`




## Installation

If [available in Hex](https://hex.pm/docs/publish), the package can be installed
by adding `extractly` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [
    {:extractly, "~> 0.1.0"}
  ]
end
```

Documentation can be generated with [ExDoc](https://github.com/elixir-lang/ex_doc)
and published on [HexDocs](https://hexdocs.pm). Once published, the docs can
be found at [https://hexdocs.pm/extractly](https://hexdocs.pm/extractly).
