E102: A semicolon is missing

Every statement in Turf ends with a semicolon ;. This error means Turf finished reading one statement and found the start of the next one without a ; in between.

mut x: int = 5            // no semicolonreturn x;

Turf tells you the position where the next thing started, which is just after where the semicolon belongs. So look at the end of the line above the one it points to:

mut x: int = 5;return x;

Where it applies: a variable declaration, an assignment, a function call on its own, return, break, continue, and the ; after a do { ... } while condition; loop.

Where it doesn’t: after a block’s closing } for if, while, for, a function, a struct, an enum – those end with the brace.

Run turf --explain E102 in a terminal to read this again.
