# v0.1.0

**Released:** January 2, 2026

Initial public release of Rosettes, extracted from the Bengal static site generator.

## Highlights

- **55 language lexers** — Hand-written state machines for Python, JavaScript, Rust, Go, and 51 more
- **O(n) guaranteed** — Linear time complexity, zero ReDoS vulnerabilities
- **Python 3.14t optimized** — Designed for free-threading (PEP 703) with declared GIL-free safety
- **Pygments compatible** — Drop-in CSS class compatibility
- **Parallel API** — `highlight_many()` and `tokenize_many()` for concurrent processing

## Features

### Core API

- `highlight()` — Generate formatted output with syntax highlighting
- `tokenize()` — Get raw tokens for custom processing
- `highlight_many()` — Parallel highlighting for multiple blocks
- `tokenize_many()` — Parallel tokenization

### Formatter Registry

- `get_formatter()` — Get formatter by name or alias
- `list_formatters()` — List all supported formatters
- `supports_formatter()` — Check formatter support

Built-in formatters:
- **HTML** — Semantic or Pygments-compatible CSS classes
- **Terminal** — ANSI-colored terminal output
- **Null** — No-op formatter for benchmarking

### Lexer Registry

- `get_lexer()` — Get lexer by name or alias
- `list_languages()` — List all supported languages
- `supports_language()` — Check language support

### Styling

- Semantic CSS classes (`.syntax-keyword`, `.syntax-function`, etc.)
- Pygments-compatible classes (`.k`, `.nf`, etc.)
- Line highlighting with `hl_lines`
- Line numbers with `show_linenos`

### Languages

55 languages supported:

| Category | Languages |
|----------|-----------|
| Core | Python, JavaScript, TypeScript, JSON, YAML, TOML, Bash, HTML, CSS, Diff |
| Systems | C, C++, Rust, Go, Zig, CUDA |
| JVM | Java, Kotlin, Scala, Groovy, Clojure |
| Scripting | Ruby, Perl, PHP, Lua, R, PowerShell |
| Functional | Haskell, Elixir |
| Modern | Dart, Julia, Nim, Gleam, V, Mojo, Triton |
| Config | INI, Nginx, Dockerfile, Makefile, HCL, CUE, Pkl |
| And more... | Swift, SQL, GraphQL, Markdown, XML, Protobuf, CSV, Stan, etc. |

## Installation

```bash
pip install rosettes
```

Requires Python 3.14+.

## Quick Start

```python
from rosettes import highlight

# HTML output (default)
html = highlight("def hello(): print('world')", "python")

# Terminal output
ansi = highlight("def hello(): print('world')", "python", formatter="terminal")

# Parallel processing
from rosettes import highlight_many

blocks = [
    ("def foo(): pass", "python"),
    ("const x = 1;", "javascript"),
]
results = highlight_many(blocks)
```

## Known Limitations

- 55 languages (vs Pygments' 500+)
- Python 3.14+ required
