## ⚡ Quick Start

```bash
# Install
pip install tinty

# Smart color nesting - inner groups automatically win
echo "hello world" | tinty '(h.(ll))' red,blue
# Output: "he" is red, "ll" is blue (inner has higher priority)

# Pipeline composition - colors preserved across stages
echo "hello world" | tinty 'hello' red | tinty 'world' blue
# Output: "hello" is red, "world" is blue

# Python API with type-safe constants
from tinty import colored, RED, BLUE, BOLD
print(colored("Error") | RED | BOLD)
```

---

## 🎨 What Makes Tinty Unique

### 1. 🧠 **Smart Color Nesting** (No other tool has this!)

Automatic priority-based rendering without manual z-index configuration:

```bash
# Nested regex groups - inner automatically wins
echo "hello world" | tinty '(h.(ll))' red,blue
# "he" is red, "ll" is blue (inner group has higher priority)
```

**Priority Rules:**
1. **Pipeline stage** - Later commands override earlier ones
2. **Nesting depth** - Inner regex groups override outer groups
3. **Application order** - Later applications win within same depth

### 2. 🔗 **Pipeline Composition**

Colors preserved across pipeline stages with intelligent priority:

```bash
# Both colors preserved
echo "hello world" | tinty 'hello' red | tinty 'world' blue

# Later stage overrides overlaps
echo "hello world" | tinty 'hello' red | tinty 'llo w' green
# "he" is red, "llo w" is green (overrides)
```

### 3. 🎯 **Channel Isolation**

Foreground, background, and attributes work independently:

```bash
# Background + foreground coexist in same text
echo "hello world" | tinty '(h.(ll))' bg_red,blue
# "he" = red background only
# "ll" = red background AND blue foreground (both channels!)
```

### 4. 🔍 **ANSI-Aware Pattern Matching**

Patterns match original text, ignoring existing ANSI codes:

```python
# Works on already-colored text!
colored_text = ColorizedString("H\x1b[31mello\x1b[0m World")
result = colored_text.highlight(r'Hello', ['green'])
# Pattern matches "Hello" despite ANSI codes in the middle
```

---

## 💡 Real-World Examples

### Log File Highlighting

```python
from tinty import ColorizedString

log = "ERROR: Connection failed at 10:30:45"
result = (ColorizedString(log)
    .highlight(r'ERROR', ['red', 'bold'])
    .highlight(r'\d{2}:\d{2}:\d{2}', ['blue'])
)
print(result)
# "ERROR" is red+bold, timestamp is blue
```

### Multi-Stage Pipeline Processing

```bash
# Stage 1: Highlight errors
cat log.txt | tinty 'ERROR|CRITICAL' red > /tmp/colored.txt

# Stage 2: Add timestamps (higher priority)
cat /tmp/colored.txt | tinty '\d{2}:\d{2}:\d{2}' blue
# Both colors preserved, timestamps override errors if overlapping
```

### Syntax Highlighting

```python
code = "def hello_world():"
result = (ColorizedString(code)
    .highlight(r'\b(def)\b', ['blue'])           # Keywords
    .highlight(r'[a-z_]+\w*(?=\()', ['green'])   # Functions
)
print(result)
```

### CLI Usage

#### Basic Usage

```bash
# Simple pattern matching
echo "hello world" | tinty 'l' red

# Pattern groups
echo "hello world" | tinty '(h.*o).*(w.*d)' red blue
```

#### Advanced: Nested Colors

```bash
# Nested regex groups - inner wins
echo "hello world" | tinty '(h.(ll))' red,blue
# Output: "he" is red, "ll" is blue

# Channel isolation - foreground + background
echo "hello world" | tinty '(h.(ll))' bg_red,blue
# Output: "he" = red bg, "ll" = red bg + blue fg

# Color name formats (both work)
echo "hello" | tinty 'hello' bg_red    # Official format
echo "hello" | tinty 'hello' red_bg    # Natural format (auto-normalized)
```

#### CLI Options

```bash
# List all available colors
tinty --list-colors

# Case sensitive matching
echo "Hello World" | tinty --case-sensitive 'Hello' green

# Verbose mode (debugging)
echo "test" | tinty --verbose 'test' red

# Clear all previous colors before applying new ones
echo "hello world" | tinty 'hello' red | tinty --replace-all 'world' blue
# Result: Only "world" is blue, "hello" has no color
```

### Python Library API

#### Type-Safe Constants (Recommended)

```python
from tinty import colored, txt, RED, GREEN, BLUE, YELLOW, BOLD, BG_WHITE, UNDERLINE

# Type-safe constants with operator chaining
print(colored("Success") | GREEN | BOLD)
print(txt("Warning") | YELLOW)
print(colored("Error") | RED | BOLD | BG_WHITE)
print(txt("Info") >> BLUE >> UNDERLINE)
```

#### Global Object with Constants

```python
from tinty import C, RED, BOLD

C.red("hello")              # Direct color method
C("hello") | RED | BOLD     # Factory with type-safe constants
C("hello", "red")           # Direct colorization (legacy)
```

#### Pattern Highlighting

```python
from tinty import ColorizedString

# Highlight search terms
text = "The quick brown fox jumps over the lazy dog"
highlighted = ColorizedString(text).highlight(
    r"(quick)|(fox)|(lazy)",
    ["red", "blue", "green"]
)
print(highlighted)

# Syntax highlighting
code = "def hello_world():"
result = ColorizedString(code).highlight(r"\b(def)\b", ["blue"])
print(result)
```

### Available Colors and Styles

#### Foreground Colors
`red`, `green`, `blue`, `yellow`, `magenta`, `cyan`, `white`, `black`, `lightred`, `lightgreen`, `lightblue`, `lightyellow`, `lightmagenta`, `lightcyan`, `lightgray`, `darkgray`

#### Background Colors
`bg_red`, `bg_green`, `bg_blue`, `bg_yellow`, `bg_magenta`, `bg_cyan`, `bg_white`, `bg_black`, `bg_lightred`, `bg_lightgreen`, `bg_lightblue`, `bg_lightyellow`, `bg_lightmagenta`, `bg_lightcyan`, `bg_lightgray`, `bg_darkgray`

#### Text Styles
`bright`/`bold`, `dim`, `underline`, `blink`, `invert`/`swapcolor`, `hidden`, `strikethrough`

### Type-Safe Color Constants

Use constants instead of error-prone string literals:

```python
from tinty import colored, RED, GREEN, BLUE, YELLOW, BOLD, BG_WHITE

# ✅ Type-safe with IDE autocompletion and error checking
error_msg = colored("CRITICAL") | RED | BOLD | BG_WHITE
success_msg = colored("SUCCESS") | GREEN | BOLD
warning_msg = colored("WARNING") | YELLOW

# ❌ Error-prone string literals
error_msg = colored("CRITICAL") | "red" | "typo"  # Runtime error!
```

**Benefits:**
- 🔍 **IDE Autocompletion**: Get suggestions for valid colors
- 🛡️ **Type Checking**: Catch typos at development time
- 📝 **Self-Documenting**: Clear, readable code
- 🔄 **Refactoring Safe**: Rename constants across codebase
- ⚡ **No Runtime Errors**: Invalid colors caught early

## 🎨 Advanced: Color Nesting & Priority

### Nested Regex Groups

Inner (more specific) capture groups automatically override outer ones:

```python
from tinty import ColorizedString

text = ColorizedString("hello world")

# Pattern: (h.(ll)) creates two groups
# - Group 1: "hell" (outer) → red
# - Group 2: "ll" (inner, higher priority) → blue
result = text.highlight(r'(h.(ll))', ['red', 'blue'])
print(result)
# Output: "he" is red, "ll" is blue (inner wins)
```

**Priority Rules:**
1. **Pipeline stage**: Later commands override earlier ones
2. **Nesting depth**: Inner regex groups override outer groups
3. **Application order**: Later applications win within same depth

### Channel Isolation

Foreground, background, and attributes are independent channels that can coexist:

```python
text = ColorizedString("hello world")

# Background and foreground don't conflict!
result = text.highlight(r'(h.(ll))', ['bg_red', 'blue'])
print(result)
# Output: "he" has red background
#         "ll" has BOTH red background AND blue foreground
```

**Available Channels:**
- **Foreground (fg)**: Text color (red, blue, green, etc.)
- **Background (bg)**: Background color (bg_red, bg_blue, etc.)
- **Attributes (attr)**: Bold, underline, dim, etc.

### ANSI-Aware Pattern Matching

Patterns always match the original text, even if it contains ANSI codes:

```python
# Text with existing ANSI codes
colored_text = ColorizedString("H\x1b[31mello\x1b[0m World")

# Pattern still matches "Hello" ignoring the ANSI codes in between
result = colored_text.highlight(r'Hello', ['green'])
print(result)
# Works! Pattern matched the original text "Hello World"
```

### Color Name Flexibility

Both `bg_red` and `red_bg` formats are supported:

```python
# These are equivalent:
text.highlight(r'hello', ['bg_red'])    # Official format
text.highlight(r'hello', ['red_bg'])    # Natural format (auto-normalized)
```
