Templates using <NotPlaintext> or <Plaintext> lose every entity in the compiled HTML:

<!-- before -->
<div role="separator" style="line-height: 32px"></div>   <!-- raw U+200D -->
<p>a b</p>                                               <!-- raw U+00A0 -->

<!-- after -->
<div role="separator" style="line-height: 32px">&zwj;</div>
<p>a&nbsp;b</p>

stripForHtml / stripForPlaintext re-parse the transformed HTML to handle the output markers, and the parser was decoding entities - undoing the entities transformer. Now they parse with decodeEntities: false, so the HTML comes out exactly as the transformers left it.

Also corrected the type of parse() options to ParserOptions, since they're passed to htmlparser2's Parser.

Summary by CodeRabbit

  • Bug Fixes
    • HTML marker processing now preserves entity spellings such as &nbsp;, &mdash;, and &zwj; instead of decoding them during parsing.
    • Plain-text marker processing also parses HTML without decoding entities, keeping entity handling consistent. HTML-only content remains excluded from plain-text output.

`stripForHtml` and `stripForPlaintext` re-parse the transformed HTML
to handle `<NotPlaintext>` / `<Plaintext>` markers. The parser decoded
entities, so any template using those components lost every entity
written by the `entities` transformer (`&zwj;` in Spacer/Hr, `&nbsp;`
etc. became raw characters).

Walkthrough

Both output-marker functions now parse HTML with entity decoding disabled. The parser accepts ParserOptions from htmlparser2. Tests check entity preservation in HTML and plaintext output.

Changes: Entity preservation

Layer / File(s) Summary
Configure output-marker parsing
src/utils/ast/parser.ts, src/utils/output-markers.ts, src/tests/utils/output-markers.test.ts
parse now accepts ParserOptions. stripForHtml and stripForPlaintext disable entity decoding. Tests check that entity spellings remain in the output. The plaintext test also checks that html-only content is absent.

Nitpick Add a marker-bearing entity case for stripForPlaintext.

26-28: Trivial · Maintainability & Code Quality · Quick win

Add a marker-bearing entity case for stripForPlaintext.

stripForPlaintext parses with decodeEntities: false, but no test sends an entity spelling through it. Reverting that option would not fail any test. Add a case that includes a data-maizzle-html-only marker, because an input without a marker returns unchanged.

🧪 Suggested test
       expect(out).toContain('<a href="/x">y</a>')
       expect(out).not.toContain('data-maizzle-plaintext-only')
     })
+
+    it('keeps HTML entities as written', () => {
+      const html = '<p>a&nbsp;b &zwj;</p><div data-maizzle-html-only>x</div>'
+      const out = stripForPlaintext(html)
+
+      expect(out).toContain('a&nbsp;b &zwj;')
+    })
   })

Add a marker-bearing entity test for stripForPlaintext that passes HTML
containing written entity spellings and a data-maizzle-html-only element, then
verifies the retained plaintext output preserves those spellings. This should
fail if entity decoding is enabled, while ensuring the marker triggers
processing.
