to_argv(Enumerable.t(), options()) :: argv()

Receives a key-value enumerable and converts it to argv/0.

Keys must be atoms. Keys with nil value are discarded, boolean values are converted to --key or --no-key (if the value is true or false, respectively), and all other values are converted using Kernel.to_string/1.

It is advised to pass to to_argv/2 the same set of options given to parse/2. Some switches can only be reconstructed correctly with the :switches information in hand.

Examples

iex> OptionParser.to_argv(foo_bar: "baz")
["--foo-bar", "baz"]
iex> OptionParser.to_argv(bool: true, bool: false, discarded: nil)
["--bool", "--no-bool"]

Some switches will output different values based on the switches types:

iex> OptionParser.to_argv([number: 2], switches: [])
["--number", "2"]
iex> OptionParser.to_argv([number: 2], switches: [number: :count])
["--number", "--number"]
