# Rainbow CSV for Obsidian

A plugin that adds rainbow coloring to CSV content in markdown code blocks, making it easier to visually distinguish columns.

## Features

- **Rainbow Text Coloring**: Each CSV column is colored with a different rainbow color
- **Multiple Delimiter Support**: Automatically detects and supports comma, tab, semicolon, and pipe delimiters
- **Theme Aware**: Automatically adjusts colors for light and dark themes
- **Plain Text Format**: Preserves original CSV formatting - no table conversion
- **Easy Toggle**: Quick enable/disable via command palette
- **Customizable**: Settings panel for configuration options

## Usage

1. **Create CSV Code Blocks**: Use the `csv` language identifier in your markdown code blocks:

```csv
name,age,city,country
John,25,New York,USA
Jane,30,London,UK
Bob,35,Paris,France
```

2. **Automatic Coloring**: Each column will be automatically colored with different rainbow colors:
   - Column 1: Red
   - Column 2: Orange  
   - Column 3: Yellow
   - Column 4: Green
   - Column 5: Blue
   - And so on... (15 colors total, cycling for more columns)

3. **Toggle On/Off**: Use the command palette (`Ctrl/Cmd + P`) and search for "Toggle Rainbow CSV"
