Summary

Functions

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!(date, format_string, formatter \\ Default)

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

Callbacks

Functions

format(date, format_string, formatter \\ Default)

Specs

format(Timex.Types.calendar_types, String.t, atom | nil) ::
  {:ok, String.t} |
  {:error, term}

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

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

Specs

format!(Timex.Types.calendar_types, String.t, atom | nil) ::
  String.t |
  no_return

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

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

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

Specs

format_token(atom, Timex.Types.calendar_types, list, list, list) ::
  String.t |
  {:error, term}

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

Specs

format_token(String.t, atom, Timex.Types.calendar_types, list, list, list) ::
  String.t |
  {:error, term}

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)

Specs

lformat!(Timex.Types.calendar_types, String.t, String.t, atom | nil) ::

validate(format_string, formatter \\ Default)

Specs

validate(String.t, atom | nil) ::
  :ok |
  {:error, term}
