描述
Similar to #5557.
Assume following code:
@external
pub fn wibble()
The build tool gives this vague message:
error: Syntax error
┌─ C:\Users\user\projects\test_gleam\src\test_gleam.gleam:2:1
│
2 │ pub fn wibble()
│ ^^^ I was not expecting this
Found the keyword `pub`, expected one of:
- `(`
It could be improved like:
error: Syntax error
┌─ C:\Users\user\projects\test_gleam\src\test_gleam.gleam:1:1
│
1 │ @external
│ ^^^^^^^^^ This attribute is incomplete
Found the keyword `pub`, expected one of:
- `(`
