### Proxy and Tunnel Communication

Source: https://vrp-framework.github.io/vRP/dev/index

Details on how extensions can listen to proxy/tunnel calls and how to access these interfaces for inter-resource communication.

```APIDOC
## Proxy and Tunnel

### Proxy Interface
Extensions can define functions in the `proxy` table to expose them. These interfaces can be accessed by other resources using `Proxy.getInterface()`.

**Example:**
```lua
MyExt.proxy = {}
function MyExt.proxy:getInfo() 
  -- implementation
end

-- Accessing the interface from another resource:
local my_ext = Proxy.getInterface("vRP.EXT.MyExt")
local info = my_ext.getInfo()
```

### Tunnel Interface
Extensions can define functions in the `tunnel` table to be called remotely. These are typically used for client-server or server-client communication.

**Example:**
```lua
-- Client-side tunnel definition:
MyExt.tunnel = {}
function MyExt.tunnel:test() 
  -- implementation
end

-- Server-side calling the client tunnel:
function MyExt.event:playerSpawn(user, first_spawn)
  self.remote._test(user.source) -- Using _ signifies fire-and-forget
end

-- Client-side calling the server tunnel:
function MyExt.event:playerDeath()
  self.remote._test() -- Calls the server-side tunnel function
end
```

**Note:** Extensions should not use proxy for communication between themselves. Use tunnels for this purpose.
```

self.interval
```

--------------------------------

### Cloak Module

Source: https://vrp-framework.github.io/vRP/dev/index

Manages character cloaks, including uniforms and customization.

```APIDOC
## Cloak Module

### Description
This module handles character cloaks, such as uniforms and other wearable items, allowing for customization.

### User-Side Extensions
- `self.cdata.pre_cloak` - Data related to the player's cloak.
- `User:setCloak(cloak)` - Sets a cloak for the user.
- `User:removeCloak()` - Removes the user's cloak.
- `User:hasCloak()` - Checks if the user has a cloak equipped.

### Server-Side Extensions
- `self.cfg` - Configuration for the cloak module.

### Menu
- `cloakroom` - The cloakroom menu, allowing access to different cloak types.
```

--------------------------------

### Profiler Utility

Source: https://vrp-framework.github.io/vRP/dev/index

Information on how to enable and use the embedded ELProfiler for profiling Lua code within vRP resources.

```APIDOC
## Profiler

vRP integrates ELProfiler for profiling Lua code. Resources that load `@vrp/lib/utils.lua` are automatically set up for profiling. To use the profiler, it must be enabled in `cfg/modules.lua`. This tracks coroutines for profiling. The overhead is generally low, making it suitable for live servers.

Two options are available in the main and admin menus to profile client-side or server-side code, respectively. Profiling uses a statistical/sampling method, so long profiling periods have low memory usage, but there is an overhead due to the Lua debug hook.
```

--------------------------------

### VRP Home Permission Check

Source: https://vrp-framework.github.io/vRP/dev/index

Defines the permission syntax for checking home ownership or access using the `!home` command. It allows specifying a home name and number for more precise checks.

```lua
`!home[.<name>[.<number>]]`
name  |  (optional) home name, all `.` characters should be removed  
---
number  |  (optional) home number  
Example
`!home` |  has a home  
---
`!home.HLM Vinewood` |  lives at `HLM Vinewood`  
`!home.HLM Vinewood.5` |  lives at `5, HLM Vinewood`
```

--------------------------------

### vRP Proxy API

Source: https://vrp-framework.github.io/vRP/dev/index

Functions for managing proxy interfaces. `Proxy.addInterface` registers a table of functions as an interface, and `Proxy.getInterface` retrieves an existing interface, optionally with a specific identifier.

```lua
-- add event handler to call interface functions
-- name: interface name
-- itable: table containing functions
Proxy.addInterface(name, itable)

-- get a proxy interface
-- name: interface name
-- identifier: (optional) unique string to identify this proxy interface access; if nil, will be the name of the resource
Proxy.getInterface(name, identifier)
```

--------------------------------

### vRP Extension Proxy Interface Access
