Overrideable constants
Static configuration pieces that affect compilation

const

Constant definition.
Constants can be used all across functions, exported and imported. If a constant is defined using ?= , it can be overridden by value via compiler flags or imported values.
1
-- This can be overridden with -const "TARGET_PEER_ID = \"other peer id\""
2
const TARGET_PEER_ID ?= "this is a target peer id"
3
​
4
-- This constant cannot be overridden
5
const SERVICE_ID = "service id"
Copied!
You can assign only literals to constants. Constant type is the same as literal type. You can override only with a subtype of that literal type.
