Markdown to HTML Converter

Converts Markdown files to beautifully styled HTML with inline CSS, optimized for WeChat Official Account and other platforms.

Execution

Agent Execution: Use bun .agents/skills/baoyu-markdown-to-html/scripts/main.ts <markdown_file> [options].

Script	Purpose
scripts/main.ts	Main entry point

Path Requirements

• CWD: Must be run from the vault root.
• Input: <markdown_file> must be an absolute path or relative to vault root.
• Output: .html file is created in the same directory as the input file.

Workflow

Step 0: Pre-check (Chinese Content)

Condition: Only execute if input file contains Chinese text.

Detection:

1. Read input markdown file
2. Check if content contains CJK characters (Chinese/Japanese/Korean)
3. If no CJK content → skip to Step 1

Format Suggestion:

If CJK content detected AND baoyu-format-markdown skill is available:

Use AskUserQuestion to ask whether to format first. Formatting can fix:

• Bold markers with punctuation inside causing ** parse failures
• CJK/English spacing issues

If user agrees: Invoke baoyu-format-markdown skill to format the file, then use formatted file as input.

If user declines: Continue with original file.

Step 1: Determine Theme

Theme resolution order (first match wins):

1. User explicitly specified theme (CLI --theme or conversation)
2. If none found → use AskUserQuestion to confirm

Theme	Description
default (Recommended)	Classic - traditional layout, centered title with bottom border, H2 with white text on colored background
grace	Elegant - text shadow, rounded cards, refined blockquotes
simple	Minimal - modern minimalist, asymmetric rounded corners, clean whitespace
modern	Modern - large radius, pill-shaped titles, relaxed line height (pair with --color red for traditional red-gold style)

Step 1.5: Determine Citation Mode

Default: Off. Do not ask by default.

Enable only if the user explicitly asks for "微信外链转底部引用", "底部引用", "文末引用", or passes --cite.

Behavior when enabled:

• Ordinary external links are rendered with numbered superscripts and collected under a final 引用链接 section.
• https://mp.weixin.qq.com/... links stay as direct links and are not moved to the bottom.
• Bare links where link text equals URL stay inline.

Step 2: Convert

bun .agents/skills/baoyu-markdown-to-html/scripts/main.ts <markdown_file> --theme <theme> [--cite]

Step 3: Report Result

Display the output path from JSON result. If backup was created, mention it.
