Examples

defmodule Example do
    alias Rediscl

    def example_one do
        {:ok, _} = Rediscl.Query.set("key:1", "value1")
    end

    def example_two do
        {:ok, value} = Rediscl.Query.get("key:1")
    end

    def example_three do
        {:ok, list_values} = Rediscl.Query.mget(["key:1", "key:2", "key:3"])
    end

    def example_jsonable_one do
      ## If you are only going to use it with a key for response
      ## For this example, options are given based on the Jason library.
      {:ok, _} =
        Rediscl.Query.get(%{key: 1}, 
          [{:json_response, true}, {:json_response_opts, [{:keys, :atoms!}]}])
    end
    
    def example_jsonable_two do
      ## If you are only going to use it with key and value.
      {:ok, _} =
        Rediscl.Query.set(%{key: 1}, %{value: 1}, 
          [{:jsonable, true}, {:encode_key, true}])
    end

    def example_jsonable_three do
      ## If you're going to use a query with a lot of keys and a value.
      {:ok, _} =
        Query.smove(%{key: 2}, %{key: 1}, "value3",
          [{:jsonable, true}, {:encode_multiple_keys, true}])
    end

    def example_jsonable_four do
      ## If you're going to use a query with a lot of keys.
      {:ok, _values} = 
        Query.sunion([%{key: 1}, "key:2"],
          [{:jsonable, true}, {:encode_multiple_keys, true}])
    end    
end

defmodule ExamplePipeBuilder do
    import Rediscl.Query.Pipe
    alias Rediscl.Query

    def example do
        query = begin set: ["key:10", "1"],
                      mset: ["key:11", "value2", "key:12", "value3"],
                      lpush: ["key:13", ["-1", "-2", "-3"]],
                      rpush: ["key:14", ["1", "2", "3"]],
                      lrange: ["key:13", 0, "-1"],
                      lrem: ["key:13", 1, "-1"]

        {:ok, results} = Query.run_pipe(query)
    end
end

Use rediscl for Mix.Task

import Mix.Rediscl
alias Rediscl

def run(_) do
    Mix.Task.run "app.start"
    
    ### Your codes
    Rediscl.Query.set("key:1", "value1")
    ### Your codes
end
