Function do_expr_ok_test

core/src/parser.rs:2958–2978

Wrapper around `do_ok_test` to parse an expression. Given that expressions alone are not valid statements, we have to put them in a statement to parse them. In doing so, we can also put an extra statement after them to ensure we detect their end properly.

(input: &str, expr: Expr)

    /// valid statements, we have to put them in a statement to parse them.  In doing so, we can
    /// also put an extra statement after them to ensure we detect their end properly.
    fn do_expr_ok_test(input: &str, expr: Expr) {
        do_ok_test(
            &format!("PRINT {}, 1", input),
            &[Statement::Call(CallSpan {
                vref: VarRef::new("PRINT", None),
                vref_pos: lc(1, 1),
                args: vec![
                    ArgSpan {
                        expr: Some(expr),
                        sep: ArgSep::Long,
                        sep_pos: lc(1, 7 + input.len()),
                    },
                    ArgSpan {
                        expr: Some(expr_integer(1, 1, 6 + input.len() + 3)),
                        sep: ArgSep::End,
                        sep_pos: lc(1, 10 + input.len()),
                    },
                ],
            })],
