# tstl-simple-const-unroller
TypeScriptToLua plugin that performs [constant folding](https://en.wikipedia.org/wiki/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
```ts
const hour = 60 * 60;
```
Becomes:
```lua
local hour = 3600
```
## Installation
Requires a modern version of TSTL. Tested on TSTL >= 1.22.0.

yarn add git+https://[email protected]/thinknathan/tstl-simple-const-unroller.git#^1.0.0 -D
# or
npm install git+https://[email protected]/thinknathan/tstl-simple-const-unroller.git#^1.0.0 --save-dev
```
2. Add `tstl-simple-const-unroller` to `tstl.luaPlugins` in `tsconfig.json`
