Provides a configurable fallback timezone. Defaults to "Etc/UTC".

# runtime.exs
config :pyro, default_timezone: "America/Chicago"

Note:

Requires a timezone database to be properly installed and configured.

Formats datetimes to localized format.

Examples

iex> format_datetime(DateTime.new!(~D[2016-05-24], ~T[13:26:08.003], "Etc/UTC"), default_timezone())
"2016-05-24 13:26 UTC"

iex> format_datetime(~N[2000-01-01 23:00:07], "Etc/UTC")
"2000-01-01 23:00 UTC"

iex> format_datetime(~N[2000-01-01 23:00:07], "Etc/UTC", :date_time_seconds_timezone)
"2000-01-01 23:00:07 UTC"

iex> format_datetime(nil, "Etc/UTC")
""

iex> format_datetime("", "Etc/UTC")
""

Safely get nested values from maps or keyword lists that may be nil or an otherwise non-map value at any point. Great for accessing nested assigns in a template.

Examples

iex> get_nested(nil, [:one, :two, :three])
nil

iex> get_nested(%{one: nil}, [:one, :two, :three])
nil

iex> get_nested(%{one: %{two: %{three: 3}}}, [:one, :two, :three])
3

iex> get_nested(%{one: %{two: [three: 3]}}, [:one, :two, :three])
3

iex> get_nested([one: :nope], [:one, :two, :three])
nil

iex> get_nested([one: :nope], [:one, :two, :three], :default)
:default

@spec toggle_class(js :: map(), classes :: String.t(), opts :: keyword()) :: map()

A JS function to toggle CSS classes, since Phoenix does not yet provide one out of the box.

Examples

toggle_class("rotate-180 bg-green", to: "#icon")

Translates the errors for a field from a keyword list of errors.
