## Quick Reference

### Using Styled Output

```rust
// CLI output with colors
use vtcode_core::utils::colors::style;
println!("{}", style("Success").green());
println!("{}", style("Error").red().bold());

// TUI widgets
use vtcode_core::utils::style_helpers::{ColorPalette, render_styled};
use ratatui::text::Span;

let palette = ColorPalette::default();
let span = Span::styled("Text", palette.success);
```

### Converting Styles

```rust
use anstyle::Style;
use vtcode_core::utils::ratatui_styles::anstyle_to_ratatui;

let anstyle = Style::new().bold().fg_color(Some(anstyle::Color::Ansi(anstyle::AnsiColor::Green)));
let ratatui_style = anstyle_to_ratatui(anstyle);
```

### Parsing Configuration

```rust
use vtcode_core::ui::tui::ThemeConfigParser;

// Parse Git color syntax
let git_style = ThemeConfigParser::parse_git_style("bold red #ff0000")?;

// Parse LS_COLORS syntax
let ls_style = ThemeConfigParser::parse_ls_colors("01;34")?;

// Parse flexibly (tries Git first, then LS)
let style = ThemeConfigParser::parse_flexible("green")?;
```

## Key Crates

| Crate           | Version | Purpose                             |

| `anstyle`       | 1.0     | ANSI style abstraction              |
| `anstyle-git`   | 1.1     | Git color config parsing            |
| `anstyle-ls`    | 1.0     | LS_COLORS parsing                   |
| `anstyle-parse` | 0.2     | ANSI escape sequence parsing        |
| `anstyle-query` | 1.0     | Terminal color capability detection |

## Architecture Overview

```
User Config (TOML)
    ↓
System Config (Git/LS_COLORS)
    ↓
ThemeConfigParser
    ↓
Style Objects (anstyle::Style)
     CLI Output (render)
     TUI Output (ratatui conversion)
```

## Testing

Run styling tests:

```bash
cargo test vtcode_ui           # UI/styling tests
cargo test style_helpers       # Style helper tests
cargo test theme_parser        # Config parser tests
cargo test --lib              # All library tests
```

Run quality checks:

```bash
cargo clippy --lib            # Lint check
cargo fmt --check             # Format check
cargo check                   # Compile check
```

## Contributing

When adding new styling features:

1. **Follow the pattern**: Use `ColorPalette`, `style_from_color_name()`, `render_styled()`
2. **No hardcoded colors**: All colors go through helpers
3. **Add tests**: Unit tests for new functions
4. **Update docs**: Add to relevant doc files
5. **Run checks**: clippy, fmt, test must pass
