.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 game client searches each subfolder of ...\Interface\AddOns\
(only one level deep) for .toc files having the same name as the subfolder. This .toc file has instructions of the following format:
- Metadata printed as
## TagName : tagValue
, where whitespace is trimmed (except at the start of a line) - Comments printed as
# this is a comment
ignored by the client - A list of files to be loaded as
myFile.xml
orsubfolder/anotherFile.lua
## Interface: 100206 ## Title: Waiting for Godot ## Notes: Nothing to be done. ## Version: 4.2 Vladimir.xml Estragon.lua libs/SomeEmbeddedLibrary.lua # This is a comment
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
- SomeEmbeddedLibrary.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
## Interface: 100206
The interface metadata specifies which version of the game client the addon has been made for. This field prevents users from experiencing errors by loading out-of-date addons or mixing Retail and Classic; unless they explicity ignore warnings and choose "Load out of date addons". Omitting this field causes the game to treat the addon as always out of date.
There are a number of ways to get the current interface version:
- It probably is 100206 (retail) or 11501 (classic)
- But these numbers are maintained locally, so they might be out of date.
- Use GetBuildInfo
- In particular,
/dump select(4, GetBuildInfo())
should output the correct version to your chat frame. - Extract FrameXML and check FrameXML.toc
- Launch wow with the
-console
flag, then at the login screen, activate the console using the `/~ key, and typeExportInterfaceFiles code
to extract FrameXML files into World of Warcraft\BlizzardInterfaceCode. - Steal it from another AddOn
- Recently updated AddOns, which are not listed as "out of date" by the client contain the latest Interface version in their toc tag.
Prior to patch 8.2.0:
- View FrameXML.toc online
- For instance at wowcompares.
Display in the addon list
The following metadata change how an addon appears in the addon list.
These tags support localization, which may written by appending a hyphen and the locale code to the tag name, such as Title-enGB
. See Localization for a full list of current locale codes.
Coloring is possible via UI escape sequences |c########
.
- Title
- String - The name to display on the AddOns list (default: name of the addon's folder).
## Title: Waiting for Godot ## Title-frFR: En attendant Godot
- Notes
- String - The description displayed when the user hovers over the addon entry in the AddOns list.
## Notes: This word is |cFFFF0000red!
Loading conditions
The following metadata changes when and how an addon loads:
- RequiredDeps, Dependencies, or any word beginning with "Dep"
- String - A comma-separated list of addon (directory) names that must be loaded before this addon can be loaded.
## Dependencies: someAddOn, someOtherAddOn
- OptionalDeps
- String - A comma-separated list of addon (directory) names that should be loaded before this addon if they can be loaded.
## OptionalDeps: someAddOn, someOtherAddOn
- LoadOnDemand
- Number - If this value of this tag is "1", the addon is not loaded when the user first logs in, but can be loaded by another addon at a later point. This can be used to avoid loading situational addons.
## LoadOnDemand: 1
- LoadWith
- String - A comma-separated list of addon (directory) names that, when loaded, will cause the client to load this LoadOnDemand addon as well.
## LoadWith: someAddOn, someOtherAddOn
- LoadManagers
- String - A comma-separated list of addon (directory) names; if no addons on this list are loaded, the client will load your addon when the user logs in; if at least one addon on this list is loaded, your addon is treated as LoadOnDemand. An example of a LoadManager is AddonLoader.
- SavedVariables
- String - A comma-separated list of variable names in the global environment that will be saved to disk when the client exits, and placed back into the global environment when your addon is loaded; the variables are not available before the ADDON_LOADED event fires for your addon. See Saving variables between game sessions.
## SavedVariables: foo, bar
- SavedVariablesPerCharacter
- String - A comma-separated list of variable names in the global environment that will be saved to disk when the client exits, and placed back into the global environment when your addon is loaded for a particular character. Note that PerCharacter saved variables are only loaded for the character for which they were saved.
## SavedVariablesPerCharacter: somePercharVariable
- DefaultState
- String - Determines whether the addon is enabled by default when first installed. If the value of this tag is "disabled", the user must explicitly enable the addon in the addons list before it is loaded.
## DefaultState: enabled
Informational
The following metadata do not change how an addon behaves, but may be accessed using GetAddOnMetadata:
- Author
- String - The AddOn author's name, displayed
- Version
- String - The AddOn version. Some automatic updating tools may prefer that this string begins with a numeric version number.
- X-_____
- String - Any custom metadata prefixed by "X-", such as "X-Date", "X-Website" or "X-Feedback"
Restricted
- Secure
- Number - If the value of this tag is 1 and the addon is digitally signed by Blizzard, its code is considered secure.
Notes
- WoW reads up to the first 1024 characters of each line only. Additional characters are ignored and do not cause an error.
- The list of files may be edited while the game is open (taking effect after
/reload
), but changing metadata has no effect and any files must have already been inside the AddOns folder
Patch changes
- Patch 9.0.1 (2020-10-13): /reload recognizes changes to TOC metadata and entirely new files.
- Patch 4.0.1 (2010-10-12): /reload recognizes changes to the file order.
- Patch 2.1.0 (2007-05-22): Added LoadManagers metadata
- Patch 1.11.0 (2006-06-19): Added Secure metadata
- Patch 1.9.0 (2006-01-03): Added LoadWidth metadata
