Marko Version: 5.24.0

Details

Marko seems to be dropping the closing ' of a quoted attribute value inside a script. See https://github.com/snyamathi/marko-repro/blob/master/template.marko#L6 as a concrete example / reproduction repo.

This seems to be a regression and did not happen until sometime recently. However, it might be something to do with Babel rather than Marko.

$ const foo = "bar"

<script>window.baz='${foo}';</script>

Expected Behavior

It should render

<script>window.baz='bar';</script>

but it instead renders - note the closing ' is missing after 'bar

<script>window.baz='bar;</script>

Possible Fix

Unsure, but this is the compiled Marko template for the above component

// Compiled using [email protected] - DO NOT EDIT
"use strict";

exports.__esModule = true;
exports.default = void 0;
var _index = require("marko/dist/runtime/html/index.js");
var _renderer = _interopRequireDefault(require("marko/dist/runtime/components/renderer.js"));
function _interopRequireDefault(obj) { return obj && obj.__esModule ? obj : { default: obj }; }
const _marko_componentType = "2pyMv7mw",
  _marko_template = (0, _index.t)(_marko_componentType);
_marko_template.path = __filename;
var _default = _marko_template;
exports.default = _default;
const _marko_component = {};
_marko_template._ = (0, _renderer.default)(function (input, out, _componentDef, _component, state, $global) {
  const foo = "bar";
  out.w("<script>window.baz='bar;</script>");
}, {
  t: _marko_componentType,
  i: true
}, _marko_component);
_marko_template.meta = {
  id: _marko_componentType
};

I'm also not sure that the '${foo}' syntax is correct. It works if I use JSON.strinfigy but that removes protection against closing the script tag.

Additional Info

Your Environment

Steps to Reproduce

Clone the following repo and npm start. You'll notice that the markup that comes out of this is invalid and causes an error:

https://github.com/snyamathi/marko-repro/blob/master/template.marko#L6

$ curl localhost:8080
<body>
  <h1>Hello</h1>
  <script>
    window.name = "Frank;
  </script>
  ...
