Tired of rewriting the same code for all your bots? The Common Bot Library (CBL) is for you.

CBL is an asynchronous .NET library of API wrappers designed to help with typical bot commands. Things like weather, definitions, movie information, etc. are all readily available for your projects.

ICalculatorService calc = new NCalcService();
var result = await calc.EvaluateAsync("1 + (3 / (23 - 5) * 6)");
Console.WriteLine(result); // 2

You can check out the full list of services here.

If you're using Visual Studio, you can install this library by following these instructions.
The package name on NuGet is CommonBotLibrary. Note: this library targets .NET Standard 1.6.

You have two choices for services that require API keys or other tokens.

1. Construct the service by passing in the necessary keys as arguments.
2. Load in tokens from a file once, then forget about 'em.

/* Method 1 */
var service = new GoogleService("platformKey", "engineId");
var results = await service.SearchAsync("dogs");

/* Method 2 */
await Tokens.LoadAsync("mytokens.json");
var service = new GoogleService(); // notice we don't pass any keys in!
var results = await service.SearchAsync("dogs");

In the second example, we keep a JSON file with our API keys and import them before creating our services. This process only needs to be done once unless your tokens file changes.

What if your project has extra services that need API keys? For example, take this token file:

{
  "OpenWeatherMap": "Im_a_key_that_CBL_recognizes",
  "MyCustomDatabaseString": "Im_a_custom_key"
}

You can take advantage of the CBL token system by subclassing the Tokens class.

public class MyCustomTokens : Tokens
{
    [JsonProperty]
    public string MyCustomDatabaseString { get; set; } // don't forget the setter!
}

Then, instead of calling LoadAsync("mytokens.json") normally, you would use your custom token class as a typeparam:

await Tokens.LoadAsync<MyCustomTokens>("mytokens.json");
var databaseConnection = MyCustomTokens.MyCustomDatabaseString;

Now you can use all the CBL services plus your own custom services without having to worry about API keys.
