# 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`.

| Script | Purpose |
|--------|---------|
| `scripts/main.ts` | Main entry point |

## Preferences (EXTEND.md)

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

```bash
# Check project-level first
test -f .canghe-skills/canghe-markdown-to-html/EXTEND.md && echo "project"

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

**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 `canghe-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 `canghe-format-markdown` skill to format the file, then use formatted file as input.

**If user declines**: Continue with original file.

### Step 1: Confirm Theme

Before converting, use AskUserQuestion to confirm the theme (unless user already specified):

| Theme | Description |
|-------|-------------|
| `default` (Recommended) | 经典主题 - 传统排版，标题居中带底边，二级标题白字彩底 |
| `grace` | 优雅主题 - 文字阴影，圆角卡片，精致引用块 |
| `simple` | 简洁主题 - 现代极简风，不对称圆角，清爽留白 |

### Step 2: Convert

```bash
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

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

**Options:**

| Option | Description | Default |
|--------|-------------|---------|
| `--theme <name>` | Theme name (default, grace, simple) | default |
| `--title <title>` | Override title from frontmatter | |
| `--keep-title` | Keep the first heading in content | false (removed) |
| `--help` | Show help | |

**Examples:**

```bash
