# Change \_VERSION global to "Luau"

## Summary
|
||
|
|
|
||
|
|
Change \_VERSION global to "Luau" to differentiate Luau from Lua
|
||
|
|
|
||
|
|
## Motivation
|
||
|
|
|
||
|
|
Provide an official way to distinguish Luau from Lua implementation.
|
||
|
|
|
||
|
|
## Design
|
||
|
|
|
||
|
|
We inherit the global string \_VERSION from Lua (this is distinct from Roblox `version()` function that returns a full version number such as 0.432.43589).
|
||
|
|
|
||
|
|
The string is set to "Lua 5.1" for us (and "Lua 5.2" etc for newer versions of Lua.
|
||
|
|
|
||
|
|
Since our implementation is sufficiently divergent from upstream, this proposal suggests setting \_VERSION to "Luau".
