feat: Complete markdown syntax refinement and variable protection
✅ New cleaner syntax implemented: - [card:type] instead of [card type='type'] - [button:style](url)Text[/button] instead of [button url='...' style='...'] - Standard markdown images:  ✅ Variable protection from markdown parsing: - Variables with underscores (e.g., {order_items_table}) now protected - HTML comment placeholders prevent italic/bold parsing - All variables render correctly in preview ✅ Button rendering fixes: - Buttons work in Visual mode inside cards - Buttons work in Preview mode - Button clicks prevented in visual editor - Proper styling for solid and outline buttons ✅ Backward compatibility: - Old syntax still supported - No breaking changes ✅ Bug fixes: - Fixed order_item_table → order_items_table naming - Fixed button regex to match across newlines - Added button/image parsing to parseMarkdownBasics - Prevented button clicks on .button and .button-outline classes 📚 Documentation: - NEW_MARKDOWN_SYNTAX.md - Complete user guide - MARKDOWN_SYNTAX_AND_VARIABLES.md - Technical analysis

# ✅ CLEAN MARKDOWN - NO MORE HTML POLLUTION! 🎉
|
||||
|
||||
## Problem Identified & Fixed!
|
||||
|
||||
---
|
||||
|
||||
## 🔴 The Problem You Reported
|
||||
|
||||
### **What You Saw:**
|
||||
1. Click "Markdown" button
|
||||
2. See HTML code with `<p>` and `<br>` tags ❌
|
||||
3. Mixed HTML + markdown syntax (messy!)
|
||||
4. Switch back to visual → More `<p>` and `<br>` added
|
||||
5. **Endless pollution!** ❌
|
||||
|
||||
### **Root Cause:**
|
||||
```typescript
|
||||
// OLD (BROKEN) FLOW:
|
||||
Visual Builder (blocks)
|
||||
↓
|
||||
blocksToHTML() → Adds <p> and <br>
|
||||
↓
|
||||
htmlToMarkdown() → Tries to clean, but messy
|
||||
↓
|
||||
"Markdown mode" shows: <p>, <br>, mixed syntax ❌
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## ✅ The Solution
|
||||
|
||||
### **New Clean Flow:**
|
||||
```typescript
|
||||
// NEW (FIXED) FLOW:
|
||||
Visual Builder (blocks)
|
||||
↓
|
||||
blocksToMarkdown() → Direct conversion!
|
||||
↓
|
||||
Markdown mode shows: Clean markdown ✅
|
||||
```
|
||||
|
||||
### **Key Insight:**
|
||||
**Skip HTML entirely when converting blocks ↔ markdown!**
|
||||
|
||||
---
|
||||
|
||||
## 🛠️ What Was Built
|
||||
|
||||
### **1. New Function: `blocksToMarkdown()`**
|
||||
```typescript
|
||||
// Direct conversion: Blocks → Markdown (no HTML!)
|
||||
export function blocksToMarkdown(blocks: EmailBlock[]): string {
|
||||
return blocks.map(block => {
|
||||
switch (block.type) {
|
||||
case 'card':
|
||||
return `[card type="${block.cardType}"]\n\n${block.content}\n\n[/card]`;
|
||||
case 'button':
|
||||
return `[button url="${block.link}"]${block.text}[/button]`;
|
||||
case 'divider':
|
||||
return '---';
|
||||
// ... etc
|
||||
}
|
||||
}).join('\n\n');
|
||||
}
|
||||
```
|
||||
|
||||
**Result:** Clean markdown, no `<p>`, no `<br>`! ✅
|
||||
|
||||
---
|
||||
|
||||
### **2. New Function: `markdownToBlocks()`**
|
||||
```typescript
|
||||
// Direct conversion: Markdown → Blocks (no HTML!)
|
||||
export function markdownToBlocks(markdown: string): EmailBlock[] {
|
||||
const blocks: EmailBlock[] = [];
|
||||
|
||||
// Parse [card] blocks
|
||||
const cardMatch = markdown.match(/\[card([^\]]*)\]([\s\S]*)\[\/card\]/);
|
||||
if (cardMatch) {
|
||||
blocks.push({
|
||||
type: 'card',
|
||||
cardType: extractType(cardMatch[1]),
|
||||
content: cardMatch[2].trim(), // Clean content!
|
||||
});
|
||||
}
|
||||
|
||||
// ... parse other blocks
|
||||
|
||||
return blocks;
|
||||
}
|
||||
```
|
||||
|
||||
**Result:** Direct parsing, no HTML intermediary! ✅
|
||||
|
||||
---
|
||||
|
||||
### **3. Updated EditTemplate.tsx**
|
||||
|
||||
#### **Before (BROKEN):**
|
||||
```typescript
|
||||
// Switching to markdown mode
|
||||
const html = blocksToHTML(blocks); // Adds <p>, <br>
|
||||
const markdown = htmlToMarkdown(html); // Messy conversion
|
||||
setMarkdownContent(markdown); // Shows HTML pollution ❌
|
||||
```
|
||||
|
||||
#### **After (FIXED):**
|
||||
```typescript
|
||||
// Switching to markdown mode
|
||||
const markdown = blocksToMarkdown(blocks); // Direct, clean!
|
||||
setMarkdownContent(markdown); // Shows clean markdown ✅
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 📊 Comparison
|
||||
|
||||
### **Old Flow (HTML Pollution):**
|
||||
```
|
||||
Visual Builder
|
||||
↓
|
||||
Blocks: { content: "Hello world" }
|
||||
↓
|
||||
blocksToHTML()
|
||||
↓
|
||||
HTML: "<p>Hello world</p>"
|
||||
↓
|
||||
htmlToMarkdown()
|
||||
↓
|
||||
Markdown: "<p>Hello world</p>" ❌ Still has HTML!
|
||||
```
|
||||
|
||||
### **New Flow (Clean Markdown):**
|
||||
```
|
||||
Visual Builder
|
||||
↓
|
||||
Blocks: { content: "Hello world" }
|
||||
↓
|
||||
blocksToMarkdown()
|
||||
↓
|
||||
Markdown: "Hello world" ✅ Clean!
|
||||
```

## 💡 Key Principles
|
||||
|

- Blocks ↔ Markdown: Direct, no HTML
|
||||
- Only use HTML for database & preview
|
||||
|
||||
### **2. Clean Separation**
|
||||
- **User-facing:** Markdown (clean, readable)
|
||||
- **Internal:** HTML (for compatibility)
|
||||
- **Never mix them!**
|
||||
|
||||
### **3. No Pollution**
|
||||
- Markdown mode shows pure markdown
|
||||
- No `<p>`, no `<br>`, no HTML tags
|
||||
- Clean, mobile-friendly typing

## 🎉 Summary
|
||||
|
||||
### **Problem:**
|
||||
- Markdown mode showed HTML with `<p>` and `<br>` tags
|
||||
- Pollution accumulated with mode switches
|
||||
- Not truly "markdown mode"
|
||||
|
||||
### **Solution:**
|
||||
- Created `blocksToMarkdown()` for direct conversion
|
||||
- Created `markdownToBlocks()` for direct parsing
|
||||
- Bypassed HTML entirely for markdown ↔ blocks
|
||||
- HTML only used for database & preview
|
||||
|
||||
### **Result:**
|
||||
- ✅ Clean, pure markdown in markdown mode
|
||||
- ✅ No HTML pollution ever
|
||||
- ✅ Mobile-friendly typing
|
||||
- ✅ Professional, modern approach
