Returns default options set for a specific key

Examples

# When the key is `:confirm`
iex> Adify.default(:confirm)
true

# When the key is `:digest_file`
iex> path = Adify.default(:digest_file)
iex> path == Path.join([System.user_home(), ".adify", ".digest"])
true

# When the key is `:tools_dir`
iex> path = Adify.default(:tools_dir)
iex> path == Path.join(:code.priv_dir(:adify), "tools")
true

# When the key is `:os`
iex> os1 = Adify.default(:os)
iex> {:ok, os} = Adify.SystemInfo.current_os()
iex> os1 == os
true

# When there's some other key
iex> Adify.default(:other_key)
nil

Runs an adifying process

Takes a Keyword as an argument with optional keys:

• :confirm: Boolean; Specifies whether a confirmation is needed before updating the state of the system.
• :digest_file: String, Path; Specifies the location of adify digest file generated after adification.
• :tools_dir: String, Path; Specifies the location of the directory that contains files corresponding to tools, configuration files and yaml files that is needed for adification.

Examples:

iex> tools_dir = "./test/support/tools/"
iex> digest_file = ".temp.dump"
iex> File.rm(digest_file)
iex> false = File.exists?(digest_file)
iex> {:ok, digest} = Adify.run(
...>   confirm: false,
...>   tools_dir: tools_dir,
...>   digest_file: digest_file,
...>   os: "arch_linux",
...> )
iex> true = File.exists?(digest_file)
iex> File.rm!(digest_file)
:ok
