A runtime developer console for unity.

Features:

• Reflection based api for adding custom commands
• Autocompletion and ability to add custom completion handlers
• Small codebase of ~600 loc
• Console open/close handlers
• Command history navigation
• Integrates with native logging (Debug.Log)
• Custom UI component embedding

Installation and usage

Install the unity package and add the Devconsole script to any object in the scene.

Pressing the backtick key ` should toggle the console, type help to get started.

When autocomplete suggestions pop up you can navigate them by pressing tab. You can toggle the autocomplete on/off by pressing F1.

Adding custom commands

Custom commands are just static functions with a ConsoleCommand attribute from the Ivy.Devconsole namespace, look at TestCommands.cs for some examples.

[ConsoleCommand("add", description: "add two numbers together", example: "add 10 20")]
public static int add(int a, int b) => a + b;

The supported parameter types are int, string, enum and float, optional arguments of these types are also supported.

You can also parse your arguments manually by having string[] args be the only function parameter.

If the return type of your function is not void, the return value will automatically be logged to the console.

If you specify the return type of your function as IEnumerator it will be executed as a coroutine.

Adding custom completions

Completions are static functions of void -> string[] decorated with the CompletionProvider attribute.

[CompletionProvider(commandName: "echo")]
public static string[] EchoCompletions() => new string[] { "hello world", "hello devconsole", "testing" };

You can provide completions based on commandName, paramaterName and/or paramaterType. completion methods are then assigned a priority score depending on how specific they are, and the method with the highest priority is used. You can override the priority by passing in the priorityOverride property to the constructor.

Open/close handler

Use these handlers to detect when the console changes state.

var d = FindObjectOfType<Devconsole>();
d.OnConsoleOpen(() => Debug.Log("the console is open"));
d.OnConsoleClose(() => Debug.Log("the console is closed"));
