Like Chronic, but for Elixir.
Add it as a dependency to your project:
defp deps do
[
{:chronic, "~> 1.1.2"},
]
end
Then you can use it wherever you wish:
{ :ok, time, offset } = Chronic.parse("tuesday 9am")
The time returned is a Calendar.NaiveDateTime
from the calendar package. The offset
returned is a time zone offset.
If Chronic encounters a format it doesn't recognise, it will return an error tuple:
{ :error, :unknown_format } = Chronic.parse("definitely not a known format, no siree")
If you're not sure what you're going to get back, use a case
:
input = "some user input goes here"
case Chronic.parse(input) do
{ :ok, time, offset } ->
# do something with time + offset
{ :error, :unknown_format } ->
# present a good error message to the user
end
