Cldr Units v2.1.0 TestBackend.Cldr.List View Source
Cldr backend module that formats lists.
If we have a list of days like ["Monday", "Tuesday", "Wednesday"]
then we can format that list for a given locale by:
iex> TestBackend.Cldr.List.to_string(["Monday", "Tuesday", "Wednesday"], locale: "en")
{:ok, "Monday, Tuesday, and Wednesday"}

Examples
iex> TestBackend.Cldr.List.intersperse!(["a", "b", "c"], locale: "en")
["a", ", ", "b", ", and ", "c"]
iex> TestBackend.Cldr.List.intersperse!(["a", "b", "c"], locale: "en", format: :unit_narrow)
["a", " ", "b", " ", "c"]
Intersperces a list elements into a list format according to the list pattern rules for a locale.
This function can be helpful when creating a list from Phoenix
safe strings which are of the format {:safe, "some string"}
Arguments
list
is any list of of terms that can be passed throughKernel.to_string/1
options
is a keyword list
Options
locale
is any configured locale. SeeCldr.known_locales()
. The default islocale: Cldr.get_current_locale/0
format
is one of those returned byCldr.List.list_pattern_types_for/1
. The default isformat: :standard
Examples
iex> TestBackend.Cldr.List.intersperse(["a", "b", "c"], locale: "en")
{:ok, ["a", ", ", "b", ", and ", "c"]}
iex> TestBackend.Cldr.List.intersperse(["a", "b", "c"], locale: "en", format: :unit_narrow)
{:ok, ["a", " ", "b", " ", "c"]}
iex> TestBackend.Cldr.List.intersperse(["a", "b", "c"], locale: "fr")
{:ok, ["a", ", ", "b", " et ", "c"]}
iex> TestBackend.Cldr.List.intersperse([1,2,3,4,5,6])
{:ok, [1, ", ", 2, ", ", 3, ", ", 4, ", ", 5, ", and ", 6]}
iex> TestBackend.Cldr.List.intersperse(["a"])
{:ok, ["a"]}
iex> TestBackend.Cldr.List.intersperse([1,2])
{:ok, [1, " and ", 2]}
list_pattern_styles_for(Cldr.locale()) :: [atom()]
Returns the styles of list patterns available for a locale.
Returns a list of atom
s of of the list format styles that are
available in CLDR for a locale.
Example
iex> TestBackend.Cldr.List.list_pattern_styles_for("en")
[:or, :or_narrow, :or_short, :standard, :standard_narrow, :standard_short,
:unit, :unit_narrow, :unit_short]
list_patterns_for(Cldr.locale()) :: Map.t()
Returns the list patterns for a locale.
List patterns provide rules for combining multiple items into a language format appropriate for a locale.
Example
iex> TestBackend.Cldr.List.list_patterns_for "en"
