Moho Script Helper

Lua autocomplete, stubs, and snippets for Moho scripting.

Features

• 🚀 Autocomplete for Moho API — Full IntelliSense for Moho modules, classes, and their properties (moho., LM., MOHO., and more)
• 📁 Moho Stubs — Bundled moho-stubs.lua provides accurate type hints for all Moho classes, modules, properties, and functions with proper error checking
• 🧠 Error Checking — Get real-time feedback on your code with proper type checking
• 🎨 Code Snippets — Ready-to-use templates for common Moho script patterns:

Snippets Available

Requirements

• VS Code 1.125.0 or higher
• Lua Language Server extension

Supported Moho Versions

✅ Supports Moho 14.4 and all versions up to it.

Installation

1. Install from the VS Code Marketplace
2. Restart VS Code
3. Open a .lua file
4. Start typing MOHO. or LM. or LM.GUI. — autocomplete will appear instantly!
5. To create a new script from scratch, type snm (for a menu script) or snt (for a tool script) and press Enter. Then type your desired script name — it will automatically update throughout the entire script!

Type Hinting Recommendations

To get the best autocomplete, type checking, and IntelliSense experience, follow these recommendations when writing Moho scripts.

Properties vs Methods

In general:

• Use . when accessing properties.
• Use : when calling methods.

Example from the Moho API:

local layer = moho.layer

-- Property access
local layerName = layer.fName

-- Method call
local layerType = layer:LayerType()

Using the correct syntax allows Lua Language Server to provide more accurate autocomplete and type checking.

Typing Existing Scripts

For scripts that were written before installing this extension, it is recommended to explicitly specify the script type on the script table.

---@type MohoScript
local Ab_MyScript = {}

This helps Lua Language Server understand that the table represents a Moho script and enables proper autocomplete for script-related fields and functions.

Typing moho in Custom Functions

When you create your own helper functions that receive a moho parameter, Lua Language Server cannot automatically determine its type.

To enable proper autocomplete and type checking, add the following annotation above the function:

---@param moho ScriptInterface
function Ab_MyScript:CreateLayer(moho)
	local layer = moho.layer
end

This is especially important for custom functions, since the type of moho is often lost once it is passed between functions.

For example:

---@param layer MohoLayer
---@param layerName string
function Ab_MyScript:RenameLayer(layer, layerName)
	layer:SetName(layerName)
end

The same approach can be used for any additional parameters in your own functions.

Function Documentation (Optional)

You can also document your custom functions with descriptions, parameter information, and return values. These descriptions appear in hover tooltips and autocomplete information.

--- Renames a layer.
---@param layer MohoLayer The layer to rename.
---@param layerName string The new layer name.
---@return boolean True if the rename operation succeeded.
function Ab_MyScript:RenameLayer(layer, layerName)
	layer:SetName(layerName)
	return true
end

Multiple Possible Types

If a parameter or return value can have multiple possible types, use the | operator:

---@param value string|boolean|nil
function Ab_MyScript:SetValue(value)
	-- function code here
end

You can use any combination of supported types:

---@param layer MohoLayer|nil
---@param name string|number
---@return string|boolean|nil

This allows Lua Language Server to understand all valid types and provide more accurate autocomplete, type checking, and error reporting.
