format!(date, format_string, formatter \\ Default)

Formats a Date, DateTime, or NaiveDateTime as a string, using the provided format string and formatter. If a formatter is not provided, the formatter used is Timex.Format.DateTime.Formatters.DefaultFormatter

format_token(token, date, modifiers, flags, width)

Given a token (as found in Timex.Parsers.Directive), and a Date, DateTime, or NaiveDateTime struct, produce a string representation of the token using values from the struct, using the default locale

format_token(locale, token, date, modifiers, flags, width)

Given a token (as found in Timex.Parsers.Directive), and a Date, DateTime, or NaiveDateTime struct, produce a string representation of the token using values from the struct

lformat(date, format_string, locale, formatter \\ Default)

Formats a Date, DateTime, or NaiveDateTime as a string, using the provided format string, locale, and formatter. If the locale provided does not have translations, "en" is used by default. If a formatter is not provided, the formatter used is Timex.Format.DateTime.Formatters.DefaultFormatter

lformat!(date, format_string, locale, formatter \\ Default)

Formats a Date, DateTime, or NaiveDateTime as a string, using the provided format string, locale, and formatter. If the locale does not have translations, "en" will be used by default. If a formatter is not provided, the formatter used is Timex.Format.DateTime.Formatters.DefaultFormatter

validate(format_string, formatter \\ Default)

Validates the provided format string, using the provided formatter, or if none is provided, the default formatter. Returns :ok when valid, or {:error, reason} if not valid

format(date, format_string, formatter \\ Default) View Source 
format(Timex.Types.valid_datetime(), String.t(), atom() | nil) ::
  {:ok, String.t()} | {:error, term()}

Formats a Date, DateTime, or NaiveDateTime as a string, using the provided format string and formatter. If a formatter is not provided, the formatter used is Timex.Format.DateTime.Formatters.DefaultFormatter.

Formatting will use the configured default locale, "en" if no other default is given.

Link to this function

format!(date, format_string, formatter \\ Default) View Source 
format!(Timex.Types.valid_datetime(), String.t(), atom() | nil) ::
  String.t() | no_return()

Formats a Date, DateTime, or NaiveDateTime as a string, using the provided format string and formatter. If a formatter is not provided, the formatter used is Timex.Format.DateTime.Formatters.DefaultFormatter.

Formatting will use the configured default locale, "en" if no other default is given.

If an error is encountered during formatting, format! will raise.

lformat(date, format_string, locale, formatter \\ Default) View Source 
lformat(Timex.Types.valid_datetime(), String.t(), String.t(), atom() | nil) ::
  {:ok, String.t()} | {:error, term()}

Formats a Date, DateTime, or NaiveDateTime as a string, using the provided format string, locale, and formatter. If the locale provided does not have translations, "en" is used by default. If a formatter is not provided, the formatter used is Timex.Format.DateTime.Formatters.DefaultFormatter
