WoW:Getting the current interface number
Jump to navigation

← HOWTOs
When loading the interface, the WoW client skips over any addons whose interface version does not match its own. This is an effort to keep the client's behavior free of errors due to changes in the API. Each addon specifies (in its .toc file) the interface version with which it complies. So an addon's .toc file most likely contains a line similar to:
## Interface: 20400
Here, 20400 would mean that the addon is designed against the Patch 2.4 client (and any subsequent minor releases).
There are a number of ways to get the current interface version:
- It could be 80205
- This number is maintained locally, so it might be out of date.
- 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- Recently updated addons, which are not listed as "out of date" by the client contain the latest Interface version in their toc tag.
- Use GetBuildInfo
- In particular,
/run print((select(4, GetBuildInfo()));should output the correct version to your chat frame. - Extract FrameXML and check FrameXML.toc
- You can download Blizzard's User Interface Customization tool, use it to extract interface data, and peek at
World of Warcraft\Blizzard Interface Data (usUS)\FrameXML\FrameXML.toc - View FrameXML.toc online
- For instance at [DEPRECATED http://wowprogramming.com/utils/xmlbrowser/live/FrameXML/FrameXML.toc wowcompares].
