Baoyu Markdown To Html

Markdown to HTML Converter

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

Script Directory

Agent Execution: Determine this SKILL.md directory as SKILL_DIR, then use ${SKILL_DIR}/scripts/<name>.ts.

Preferences (EXTEND.md)

Use Bash to check EXTEND.md existence (priority order):

bashCopy code
# Check project-level first
test -f .baoyu-skills/baoyu-markdown-to-html/EXTEND.md && echo "project"

# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
test -f "$HOME/.baoyu-skills/baoyu-markdown-to-html/EXTEND.md" && echo "user"

┌──────────────────────────────────────────────────────────────┬───────────────────┐ │ Path │ Location │ ├──────────────────────────────────────────────────────────────┼───────────────────┤ │ .baoyu-skills/baoyu-markdown-to-html/EXTEND.md │ Project directory │ ├──────────────────────────────────────────────────────────────┼───────────────────┤ │ $HOME/.baoyu-skills/baoyu-markdown-to-html/EXTEND.md │ User home │ └──────────────────────────────────────────────────────────────┴───────────────────┘

┌───────────┬───────────────────────────────────────────────────────────────────────────┐ │ Result │ Action │ ├───────────┼───────────────────────────────────────────────────────────────────────────┤ │ Found │ Read, parse, apply settings │ ├───────────┼───────────────────────────────────────────────────────────────────────────┤ │ Not found │ Use defaults │ └───────────┴───────────────────────────────────────────────────────────────────────────┘

EXTEND.md Supports: Default theme | Custom CSS variables | Code block style

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. EXTEND.md default_theme (this skill's own EXTEND.md, checked in Step 0)Check Domain?
3. baoyu-post-to-wechat EXTEND.md default_theme (cross-skill fallback)
4. If none found → use AskUserQuestion to confirm

Cross-skill EXTEND.md check (only if this skill's EXTEND.md has no default_theme):

bashCopy code
# Check baoyu-post-to-wechat EXTEND.md for default_theme
test -f "$HOME/.baoyu-skills/baoyu-post-to-wechat/EXTEND.md" && grep -o 'default_theme:.*' "$HOME/.baoyu-skills/baoyu-post-to-wechat/EXTEND.md"

If theme is resolved from EXTEND.md: Use it directly, do NOT ask the user.

If no default found: Use AskUserQuestion to confirm:

Step 2: Convert

bashCopy code
npx -y bun ${SKILL_DIR}/scripts/main.ts <markdown_file> --theme <theme>

Step 3: Report Result

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

Usage

bashCopy code
npx -y bun ${SKILL_DIR}/scripts/main.ts <markdown_file> [options]

Options:

Examples:

bashCopy code
# Basic conversion (uses default theme, removes first heading)
npx -y bun ${SKILL_DIR}/scripts/main.ts article.md

# With specific theme
npx -y bun ${SKILL_DIR}/scripts/main.ts article.md --theme grace

# Keep the first heading in content
npx -y bun ${SKILL_DIR}/scripts/main.ts article.md --keep-title

# Override title
npx -y bun ${SKILL_DIR}/scripts/main.ts article.md --title "My Article"

Output

File location: Same directory as input markdown file.

• Input: /path/to/article.md
• Output: /path/to/article.html

Conflict handling: If HTML file already exists, it will be backed up first:

• Backup: /path/to/article.html.bak-YYYYMMDDHHMMSS

JSON output to stdout:

jsonCopy code
{
  "title": "Article Title",
  "author": "Author Name",
  "summary": "Article summary...",
  "htmlPath": "/path/to/article.html",
  "backupPath": "/path/to/article.html.bak-20260128180000",
  "contentImages": [
    {
      "placeholder": "MDTOHTMLIMGPH_1",
