E1010 error

Assignment to an exported or imported binding

area: names (x1xxx)
fails the build: yes
in plain Lua files: reported as W1010

The code assigns to an exported local after its declaration, or to an imported name. Importers copy an export once while the file loads, so a later assignment would never reach them; exported and imported bindings are therefore read-only. Change a table's contents instead (state.count += 1), or export functions that read and change the value.

Example

× failswowlua

export local count = 0count = count + 1

✓ compileswowlua

export local state = { count = 0 }state.count = state.count + 1

The compiler reports it like this:

error[E1010]: cannot assign to the exported binding `count`; mutate a table's contents or export accessor functions
  ┌─ src/main.wowlua:2:1
