| ### Breaking Changes | ||
@@ -23,13 +26,20 @@ - renamed `build` folder to `dist` (#130). The package file structure is now: | ||
| - Call arguments must be either all comma-separated or all space-separated, but not mixed | ||
| - unary expressions with no argument now throw `missing unaryOp argument` | ||
| - binary expressions now require the left-hand side to exist | ||
| - conditional (ternary) expressions with no condition now throw `unexpected "?"` | ||
| - `.` now throws `unexpected .` | ||
| - `()()` now throws `unexpected "("` | ||
| - `a.this`, `a.true`, `a.false`, `a.null` now match espimra and treat the property as an identifier instead of a literal or ThisExpression | ||
| ### Added | ||
| - Added a plugin system, including plugins for | ||
| - arrow expressions (`() => ...`) | ||
| - assigment and update expressions (`a = 2`, `a++`) | ||
| - comments (`/* .. */` and `// ...`) | ||
| - new expressions (`new Date()`) | ||
| - object expressions (`{a: 1, b}`) | ||
| - regex support (`/123/ig`) | ||
| - spread operator (`fn(...a)`, `[1, ...b]`, `{...c}`) | ||
| - template expressions (`` `hi ${name}` ``, `` msg`hig ${name}` ``) | ||
