Mod version in Lua - allfoxwy/UnitXP_SP3 GitHub Wiki

Tell if UnitXP_SP3 functions are available

• /script local UnitXP_SP3 = pcall(UnitXP, "nop", "nop");

The nop method always return true. So we could use a pcall to check if UnitXP SP3 is installed.

Decide UnitXP_SP3 version

• /script local compileTime = UnitXP("version", "coffTimeDateStamp");
• /script local infoString = UnitXP("version", "additionalInformation");

The coffTimeDateStamp method return UnitXP_SP3.dll COFF header's TimeDateStamp. It is a Unix epoch time indicating when did this version of UnitXP_SP3 compile. Comparing two timestamps could tell which version is new. It could be easily convert into human-readable string using Lua date() function.

The additionalInformation method return a not-important string to distinguish maintainer. It is for people who fork the project could start a different version bloodline.
