Crono

Crono is a library to work with cron expressions.

It parses cron expressions, allows calculating future runs of the schedule, and representing an expression as a human-readable description.

Basic usage

iex> Crono.parse("5 * * * *")
{:ok, %Crono.Expression{minute: 5, hour: :*, day: :*, month: :*, weekday: :*}}

iex> ~e[5 * * * *]
%Crono.Expression{minute: 5, hour: :*, day: :*, month: :*, weekday: :*}

iex> Crono.Schedule.get_next_date(~e[5 * * * *], ~N[2023-09-01T10:00:00])
~N[2023-09-01T10:05:00]

Installation

To start off, add crono to the list of your dependencies:

def deps do
  {:crono, "~> 0.1"},
end

If you want to use the ~e[] sigil for your expressions, also add import Crono.Expression to your module.
