### Basic Rule Generation

Source: https://github.com/omerlo-technologies/ex_cycle/blob/main/README.md

A quick-start example of creating a cycle and adding daily rules with specified hours.

```elixir
ExCycle.new()
|> ExCycle.add_rule(:daily, hours: [20, 10])
|> ExCycle.add_rule(:daily, interval: 2, hours: [15])

# Generates every day at 10:00 and 20:00 and every 2 days at 15:00
```

--------------------------------

### Generate Occurrences with ExCycle

Source: https://github.com/omerlo-technologies/ex_cycle/blob/main/README.md

Demonstrates how to create a new ExCycle instance, add daily rules with specific intervals and hours, and then generate occurrences starting from a given date. It shows how to take a specified number of occurrences.

```elixir
iex> ExCycle.new()
...> |> ExCycle.add_rule(:daily, interval: 2, hours: [20, 10]
...> |> ExCycle.add_rule(:daily, interval: 1, hours: [15]
...> |> ExCycle.occurrences(~D[2024-02-29])
...> |> Enum.take(5)
[~N[2024-02-29 10:00:00], ~N[2024-02-29 15:00:00], ~N[2024-02-29 20:00:00], ~N[2024-03-01 15:00:00], ~N[2024-03-02 10:00:00]]
```

--------------------------------

### Rule Generation with Duration

Source: https://github.com/omerlo-technologies/ex_cycle/blob/main/README.md

Shows how to add a daily rule with a specified hour and a duration, creating a time span. This example uses the `Duration` struct.

```elixir
ExCycle.new()
|> ExCycle.add_rule(:daily, hours: [10], duration: %Duration{hour: 2})
```

--------------------------------

### Stringify ExCycle Rule

Source: https://github.com/omerlo-technologies/ex_cycle/blob/main/README.md

Provides an example of how to stringify an `ExCycle.Rule` using a custom stringify function. This function formats rule components into a human-readable string.

```elixir
stringify = fn(field, msg_opts) ->
  msg = 
    Enum.map_join(msg_opts, ", ", fn {msg, opts} ->
      Regex.replace(~r"{%(\w+)}", msg, fn _, key ->
        opts |> Keyword.get(String.to_existing_atom(key), key) |> to_string()
      end)
    end)

  case field do
    :interval -> msg
    :times -> "at " <> msg
    :minutes -> "every hours at minutes " <> msg
    :days_of_month -> "on the " <> msg
    :days -> "on " <> msg
  end
end

ExCycle.Rule.new(:weekly, days: [:monday], hours: [10], minutes: [30])
|> ExCycle.StringBuilder.traverse_validations(stringify)
|> Enum.join(" ")

# "daily at 10:00, 10:30"
```

--------------------------------

### Rule Generation with Timezone

Source: https://github.com/omerlo-technologies/ex_cycle/blob/main/README.md

Demonstrates adding a daily rule with specific hours and a timezone, showing how to generate datetimes in a particular timezone.

```elixir
ExCycle.new()
|> ExCycle.add_rule(:daily, hours: [20, 10], timezone: "America/Montreal")

# Generates every day at 10:00 and 20:00 with timezone America/Montreal
```

--------------------------------

### Add ExCycle Dependency

Source: https://github.com/omerlo-technologies/ex_cycle/blob/main/README.md

Shows how to add the ExCycle library as a dependency in a Mix project by updating the `mix.exs` file.

```elixir
def deps do
  [
    {:ex_cycle, "~> 0.1.0"}
  ]
end
```

--------------------------------

### Configure Time Zone Database

Source: https://github.com/omerlo-technologies/ex_cycle/blob/main/README.md

Illustrates how to configure ExCycle to use a specific time zone database, such as Tzdata, either through Mix configuration or by directly calling a function.

```elixir
config :elixir, :time_zone_database, Tzdata.TimeZoneDatabase
```

```elixir
Calendar.put_time_zone_database(Tzdata.TimeZoneDatabase)
```

--------------------------------

### Rule Generation with Duration and Timezone

Source: https://github.com/omerlo-technologies/ex_cycle/blob/main/README.md

Combines duration and timezone to generate time spans with Daylight Saving Time (DST) support, creating occurrences from a specific hour to two hours later in the specified timezone.

```elixir
ExCycle.new()
|> ExCycle.add_rule(:daily, hours: [10], duration: %Duration{hour: 2}, timezone: "America/Montreal")

# Generates every day from 10:00 to 12:00 with timezone America/Montreal
```
