tstl-simple-const-unroller

TypeScriptToLua plugin that performs constant folding for simple numeric expressions:

• Addition (+)
• Subtraction (-)
• Multiplication (*)
• Division (/)
• Modulo (%)
• Exponentiation (**)

All parts of the expression must be numeric literals.

Redundancy warning: Your target Lua runtime may already perform constant folding.

Example

const hour = 60 * 60;

Becomes:

local hour = 3600
