TOC format

From Warcraft Wiki
Jump to navigation Jump to search

.toc (Table of Contents) files contain information about a particular addon (such as its name, description, saved variables, etc), as well as instructions on how the addon should be loaded by the client (for example, the order in which lua and xml files should be loaded). The file must be present, and have the same name (plus extension) as its parent folder for the addon to be recognized by the client.

Basic rules

The .toc file and addon folder name need to match, e.g. ..\Interface\AddOns\MyAddon\ and MyAddon.toc

The file may contain the following elements:

  • Metadata as ## Directive: Value
  • Comments as # this is a comment
  • A list of files as myFile.xml or subfolder\anotherFile.lua

Whitespace before # will be interpreted as the start of a filename. However, the client trims whitespace around metadata values (after the colon).

Backslashes (\) are recommended for subdirectories to prevent issues with <Include> tags.

## Interface: 100207
## Title: Waiting for Godot
## Notes: Nothing to be done.
## Version: 1.0.0

# This line is a comment

Multiple client flavors

Classic and retail versions of the game can be properly supported by including multiple TOC files in the same addon.[1] The client first searches for the respective suffix and otherwise falls back to AddonName.toc

Flavor Suffix
Dragonflight Mainline AddonName_Mainline.toc
All classic flavors AddonName_Classic.toc
Cataclysm Cataclysm Classic AddonName_Cata.toc
Wrath-Logo-Small.png Wrath of the Lich King Classic AddonName_Wrath.toc
Bc icon.gif Burning Crusade Classic AddonName_TBC.toc
WoW Icon update.png Classic Era AddonName_Vanilla.toc
  • Clients also recognize legacy suffixes -WOTLKC and -BCC.
  • Cataclysm The _Classic suffix has changed and is now used for addons that can be loaded on all Classic client flavors.
    • Files with this TOC suffix have a lower priority than other suffixes that target specific clients. For example, having both a _Cata.toc and _Classic.toc file will result in the former being used on Cataclysm Classic clients, and the latter in all other Classic client flavors.

File load order

The .toc file provides an ordered list of files to be loaded by the client. In the earlier example:

  • Vladimir.xml loads first, and is in the same folder as the .toc file
  • Estragon.lua loads second, and is in the same folder as the .toc file
  • SomeLibrary.lua loads third, and is in a subfolder called libs

Not every file must appear in a .toc list:

  • XML files may contain <Script file="nameOfAnotherFile.lua" /> or <Include file="alsoLoadThis.xml" />
  • Texture:SetTexture() and PlaySoundFile() can use images and sounds contained within the addon folder and its subfolders

Interface version

The interface field declares the version of the game client for which the addon has been made. This field guarantees that users of an addon will have a game API that is compatible with the one the author used during development.

Conversely, if addons declare an older interface than the user's current one, instability and breakages may occur because the game API changes over time. However, users may opt into this risk by ticking the "Load out of date addons" checkbox. Additionally, the omission of this field causes the game to treat the addon as always out of date.

Here is an example of how this field is declared in TOC files:

## Interface: 100207

As of Patch 10.2.7 and Patch 4.4.0, multiple Interface versions may be specified delimited by commas. The following example would declare an addon as being compatible with the latest version of all client flavors:

## Interface: 100207, 40400, 11502

Interface sources

There are a number of ways to get the current interface version.

Warcraft Wiki

This wiki maintains a set of the latest interfaces for each flavor of the game. They are displayed in the table below. Note that these values are updated by contributors, so they may occasionally be out of date.

Flavor Patch TOC version
The War Within The War Within 11.0.0 110000
Dragonflight Mainline 10.2.7 100207
Cataclysm Cataclysm Classic 4.4.0 40400
WoW Icon update.png Classic Era 1.15.2 11502


The GetBuildInfo API function will return data about the currently released game client that is available to players. For example, /dump (select(4, GetBuildInfo())) will output the interface version to your chat frame.

Enter the text "/dump select(4, GetBuildInfo())" into the chat window to display the Interface version

AddOns list formatting

The following directives change how an AddOn appears in the AddOns list. Both may be coloured using UI escape sequences (e.g. |c########|r), or localized by appending a hyphen and the locale code (e.g.Title-enGB). Later entries overwrite earlier ones, so the non-localized fallback should go first.


Name displayed in the AddOns list.
## Title: Waiting for Godot
## Title-frFR: En attendant Godot


Tooltip displayed in the AddOns list.
## Notes: This word is |cFFFF0000red|r


Path to a texture file to be shown as the icon for this addon in the addon list. Optional.
## IconTexture: Interface\Icons\TEMP


Name of a texture atlas to be shown as the icon for this addon in the addon list. Optional, and has a lower priority than IconTexture if both are set.
## IconAtlas: TaskPOI-Icon

Addon compartment integration

Dragonflight The following directives will control the registration of the addon into the Addon compartment dropdown accessible from the minimap.


Name of a global function to be executed when the dropdown list button for this addon has been clicked. This field is required to have the addon be shown in the Addon Compartment list.
## AddonCompartmentFunc: MyAddon_OnAddonCompartmentClick


Name of a global function to be executed when this dropdown list button for this addon has been highlighted. Optional.
## AddonCompartmentFuncOnEnter: MyAddon_OnAddonCompartmentEnter


Name of a global function to be executed when this dropdown list button for this addon is no longer highlighted. Optional.
## AddonCompartmentFuncOnLeave: MyAddon_OnAddonCompartmentLeave

Loading conditions

The following directives control when an AddOn loads, and any dependencies that must or may load first.


1 to delay loading until LoadAddOn().
## LoadOnDemand: 1


AddOns that must load first. Aliases include RequiredDeps and any word beginning with Dep.
## Dependencies: someAddOn, someOtherAddOn


AddOns that should load first if available.
## OptionalDeps: someAddOn, someOtherAddOn


AddOns that, once loaded, trigger this one to load. Implies LoadOnDemand.
## LoadWith: someAddOn, someOtherAddOn


AddOns that, if present, trigger this one to behave as LoadOnDemand. See AddonLoader for an example.
## LoadManagers: someAddOn, someOtherAddOn


disabled to require the user to explicitly enable the AddOn in the AddOns list.
## DefaultState: disabled

Saved variables

Main article: Saving variables between game sessions


Variables saved in WTF/[account]/SavedVariables.
## SavedVariables: MyAddOnNameFoo, MyAddOnNameBar


Variables saved in WTF/[account]/[server]/[character]/SavedVariables.
## SavedVariablesPerCharacter: MyAddOnNameAnotherVariable


The following metadata may be accessed using GetAddOnMetadata().

The AddOn author's name, displayed
The AddOn version. Some automatic updating tools may prefer that this string begins with a numeric version number.
Any custom metadata prefixed by "X-", such as "X-Date", "X-Website" or "X-Feedback"


The following tags are inaccessible to third-party AddOns.
