# Jahro Commands

Help users add runtime-callable debug commands to Unity code using Jahro's `[JahroCommand]` attribute system.

## Workflow

1. **Analyze** the user's code — identify methods that are good command candidates
2. **Generate** correct `[JahroCommand]` attributes with proper syntax
3. **Add registration** if needed (instance methods require `RegisterObject`)
4. **VERIFY** — "Enter Play Mode, press ~, check the Commands tab"

## Analyzing Code for Command Candidates

When the user shares a class, identify methods worth exposing as commands:

**Good candidates:**
- Public methods that change game state (damage, heal, spawn, teleport, reset)
- Methods used for testing and tuning (set difficulty, add currency, skip level)
- Diagnostic methods (print stats, dump state, force GC)
- Methods with simple parameter types (int, float, bool, string, Vector2, Vector3, enum)

**Skip these:**
- Unity lifecycle methods (Update, Start, Awake, OnEnable, OnDisable, OnDestroy)
- Private implementation details the developer wouldn't want to call manually
- Methods with complex parameter types (custom classes, interfaces, delegates)
- Property getters/setters (use `[JahroWatch]` for monitoring instead)

## Attribute Syntax

```csharp
[JahroCommand("command-name", "GroupName", "Short description of what it does")]
```

Constructor: `[JahroCommand(string name, string group, string description)]`

All parameters are optional. Defaults: name = method name, group = "Default", description = "".

### Naming conventions

- **Command name**: kebab-case (`"spawn-enemy"`, `"add-gold"`, `"set-difficulty"`)
- **Group name**: PascalCase or Title Case (`"Cheats"`, `"Spawning"`, `"Game"`)
- **Description**: Imperative, concise (`"Spawn enemy at position"`, `"Add gold to player"`)

### Complete example

```csharp
using JahroConsole;
using UnityEngine;

public class PlayerController : MonoBehaviour
{
    public float health = 100f;

    [JahroCommand("heal", "Player", "Restore health by amount")]
    public void Heal(float amount) { health = Mathf.Min(health + amount, 100f); }

    [JahroCommand("teleport", "Player", "Teleport to position")]
    public void Teleport(Vector3 position) { transform.position = position; }

    [JahroCommand("reset-pos", "Player", "Reset to origin")]
    public void ResetPosition() { transform.position = Vector3.zero; }

    void OnEnable()  => Jahro.RegisterObject(this);
    void OnDisable() => Jahro.UnregisterObject(this);
}
```

## Registration Pattern

### Instance methods — require RegisterObject

Any non-static method with `[JahroCommand]` needs the owning object registered so Jahro can invoke it:

```csharp
void OnEnable()  => Jahro.RegisterObject(this);
void OnDisable() => Jahro.UnregisterObject(this);
```

This same call also registers `[JahroWatch]` attributes on the class. If the class already has RegisterObject (e.g., for watchers), do not add a second call.

Read `references/common-patterns.md` for the full lifecycle pattern and anti-patterns.

### Static methods — no registration needed

Static methods are discovered via assembly scanning:

```csharp
public class DebugCommands
{
    [JahroCommand("restart-level", "Game", "Restart current level")]
    public static void RestartLevel()
    {
        UnityEngine.SceneManagement.SceneManager.LoadScene(0);
    }
}
```

### Decision guide

| Method type | Needs RegisterObject? | Why |
|:------------|:---------------------|:----|
| `public void Foo()` (instance) | Yes | Jahro needs the object reference to call it |
| `public static void Foo()` | No | Called on the class, discovered via assembly scan |
| `public void Foo()` on a class that already has RegisterObject | No extra work | Already registered |

## Supported Parameter Types

Commands accept these parameter types:

| Type | Text Mode input | Visual Mode input |
|:-----|:---------------|:-----------------|
| `int` | `42` | Number field |
| `float` | `3.14` | Decimal field |
| `bool` | `true` / `false` | Toggle switch |
| `string` | `hello world` | Text field |
| `Vector2` | `1.5 2.0` | X/Y fields |
| `Vector3` | `10 2.5 -7` | X/Y/Z fields |
| `enum` (any) | `Hard` (name) | Dropdown selector |

Maximum 3 parameters per command. For full type details, read `references/api-reference.md`.

## Command Overloads

Same command name with different parameter signatures:

```csharp
[JahroCommand("spawn-enemy", "Spawning", "Spawn one enemy at position")]
public void SpawnEnemy(Vector3 position) { /* ... */ }

[JahroCommand("spawn-enemy", "Spawning", "Spawn N enemies")]
public void SpawnEnemy(int count) { /* ... */ }
```

Text Mode resolves the correct overload by parameter count and type conversion.

## Return Values

Commands that return `string` display the result in the console log:

```csharp
[JahroCommand("get-pos", "Debug", "Print player position")]
public static string GetPlayerPosition()
{
    return $"Position: {Player.Instance.transform.position}";
}
```

## Dynamic Command Registration

For commands created at runtime instead of compile time. Use when wrapping external APIs, creating commands from data, or in non-MonoBehaviour systems.

```csharp
// No parameters
Jahro.RegisterCommand("clear-cache", "Maintenance", "Clear local cache",
    () => PlayerPrefs.DeleteAll());

// One typed parameter
Jahro.RegisterCommand<int>("add-gold", "Cheats", "Add gold",
    amount => Player.Gold += amount);

// Two parameters
Jahro.RegisterCommand<int, float>("set-stats", "Tuning", "Set health and speed",
    (health, speed) => { Player.Health = health; Player.Speed = speed; });
```

**Parameter order for dynamic registration:** `(name, description, groupName, callback)`.
This differs from the attribute order `(name, group, description)`.

Register command on existing object method:

```csharp
var mgr = FindObjectOfType<GameManager>();
Jahro.RegisterCommand("restart", "Game", "Restart level",
    mgr, nameof(GameManager.RestartLevel));
```

Cleanup:

```csharp
Jahro.UnregisterCommand("clear-cache");
Jahro.UnregisterCommand("restart", "Game");
```

Read `references/api-reference.md` for all `RegisterCommand` overloads (0-3 generic parameters).

## Command Organization

### Group naming strategy

Organize commands by functional area:

```
"Player"    — heal, teleport, reset, set-speed
"Spawning"  — spawn-enemy, spawn-wave, clear-enemies
"Cheats"    — god-mode, add-gold, unlock-all
"Game"      — restart-level, set-difficulty, skip-level
"Debug"     — dump-state, gc-collect, toggle-fps
```

### Visual Mode vs Text Mode

Commands work in both modes automatically. Consider the target audience:

- **Text Mode** — fast for developers who know command names. Autocomplete helps. Vector3 entered as `10 2.5 -7`.
- **Visual Mode** — browsable groups with descriptions, form-based parameter input. Touch-friendly on mobile. Enum parameters render as dropdown selectors.

When designing commands for QA (non-developers), prefer:
- Simple parameter types (bool, enum, int) over Vector3
- Descriptive names and descriptions
- Logical groups that match QA workflows

### Favorites and Recent

Users can star frequently-used commands for quick access. The last 10 executed commands always appear in the Recent section. Command names and groups help discoverability — be descriptive.

## Contextual Awareness

When you see these patterns in user code, proactively suggest:

| Pattern in code | Suggestion |
|:---------------|:-----------|
| `[JahroCommand]` already present | Offer improvements (better groups, descriptions, missing commands) |
| `OnGUI()` with `GUI.Button` debug commands | Migrate to `[JahroCommand]` — Visual Mode replaces the button UI |
| Public methods that modify game state | Suggest exposing as commands |
| Custom command parser (string → command) | Migrate to Jahro's typed command system |

## Verification

After generating commands, always include:

> **Verify:** Enter Play Mode → press ~ → switch to the Commands tab (or Visual Mode). Confirm your commands appear in the correct groups. Try executing one to confirm it works.

If commands don't appear, suggest the jahro-troubleshooting skill — common causes: missing RegisterObject, wrong assembly selected, JAHRO_DISABLE active.
