Bug Description

Exported session HTML files fail to open. Browser console shows:

Uncaught ReferenceError: MARKED_JS is not defined
Uncaught ReferenceError: HIGHLIGHT_JS is not defined
Uncaught ReferenceError: JS is not defined

Root Cause

Placeholders in dist/export-html/template.html are incorrectly split into multi-line format by code formatters (e.g., prettier):

Expected format:

<script>{{MARKED_JS}}</script>

Actual format:

<script>
 {
 {
 MARKED_JS;
 }
 }
</script>

The code uses .replace("{{MARKED_JS}}", markedJs) for substitution, but since the placeholder is split across lines, the replacement fails, resulting in undefined JavaScript variables in the generated HTML.

Affected Placeholders

• {{MARKED_JS}}
• {{HIGHLIGHT_JS}}
• {{JS}}

Suggested Fixes

• Protect placeholders with HTML comments to prevent formatting
• Add formatting ignore rules for .html files in the build process
• Use regex replacement in code to tolerate whitespace

Workaround

Manually edit dist/export-html/template.html and restore single-line placeholder format.

Environment
