MixReadme

Installation

def deps do
    [
        {:mix_readme, "~> 0.2.1", runtime: false}
    ]
end

Generate a README based on the moduledoc of your app.

This so you can write Doctests that get tested and have them in your README.

Usage

mix readme > README.md

Will use the default template, but you can supply your own template. These are automatically found in ["./priv/readme.eex", "./priv/README.eex", "./priv/Readme.eex", "./readme.eex", "./README.eex", "./Readme.eex"] or you can set the path in the config under the template_path key.

Available commandline arguments

Flag	Info
--app, -a	override the app variable
--module, -m	override the module variable
--template_path	set the path of the template to use
--module_file	set the path to the file where the module can be found

Resolution Order:

• Commandline Arguments
• Config
• Mix.Project

Takes these from the Mix.Project:

• app
• name
• version
• description
• elixir
• package

Takes these from the config file:

• app
• module
• template_path
• module_file

But arbitrary keys can be set in the config, so that these can be used in your template.

Example 1

mix readme --module MyApp.OddModule --module_file ./priv/odd_place/odd_module.ex > README.md

Example 2

in config/config.ex

import Config

config :mix_readme,
  module_file: "./lib/my_app.ex",
  template_path: "./docs/readme.eex",
  my_arbitrary_data: [1, 2, 3, 4, 5]

in docs/readme.eex, because we set that in the config:

    # <%= module_name %>

    Some text I want in the README but not in the moduledoc.

    ## Installation

    ```elixir
    def deps do
      [
        {:my_app, "~> <%= version %>"}
      ]
    end
    ```

    <%= module_doc %>

    <%= Enum.map(my_arbitrary_data, fn item -> %>
    - <%= item %>
    <%= end) %>

Custom Backend

By default the template format used is EEx, because this is the default Elixir templating engine. But this can be changed by setting the :backend key in the config to a module that implements the MixReadme.Backend behaviour. For instance take a look at https://github.com/thomas9911/mix_readme_mustache.

in mix.exs:

[
    {:mix_readme, "~> 0.2.0", only: :dev, runtime: false},
    {:mix_readme_mustache, "~> 0.1.0", only: :dev, runtime: false}
]

in config/config.exs:

import Config

config :mix_readme,
    backend: MixReadme.Backend.Mustache
