uloop-execute-dynamic-code

name	uloop-execute-dynamic-code
description	Execute C# code dynamically in Unity Editor via uloop CLI. Use for editor automation: (1) Prefab/material wiring and AddComponent operations, (2) Reference wiring with SerializedObject, (3) Scene/hierarchy edits and batch operations. NOT for file I/O or script authoring.

uloop execute-dynamic-code

Execute C# code dynamically in Unity Editor.

Usage

uloop execute-dynamic-code --code '<c# code>'

Parameters

--compile-only	boolean	Compile without execution
--auto-qualify-unity-types-once	boolean	Auto-qualify Unity types

Code Format

Write direct statements only (no classes/namespaces/methods). Return is optional.

// Using directives at top are hoisted
using UnityEngine;
var x = Mathf.PI;
return x;

String Literals (Shell-specific)

Shell	Method
bash/zsh/MINGW64/Git Bash	'Debug.Log("Hello!");'
PowerShell	'Debug.Log(""Hello!"");'

• AddComponent + reference wiring (SerializedObject)
• Scene/hierarchy edits
• Inspector modifications

Forbidden Operations

• System.IO.* (File/Directory/Path)
• AssetDatabase.CreateFolder / file writes
• Create/edit .cs/.asmdef files

Examples

bash / zsh / MINGW64 / Git Bash

uloop execute-dynamic-code --code 'return Selection.activeGameObject?.name;'
uloop execute-dynamic-code --code 'new GameObject("MyObject");'
uloop execute-dynamic-code --code 'UnityEngine.Debug.Log("Hello from CLI!");'

PowerShell

uloop execute-dynamic-code --code 'return Selection.activeGameObject?.name;'
uloop execute-dynamic-code --code 'new GameObject(""MyObject"");'
