🚀 Overview

Affinity is a next-generation terminal tool designed for developers who want the rich viewing experience of modern IDEs (like VS Code) directly in their command line.

Say goodbye to plain text dumps. Affinity parses your code, wraps it in beautiful Unicode borders, syntax-highlights every token flawlessly, and visually connects logical code blocks using intelligent vertical scope guides.

Advanced Tools

Affinity is more than just a viewer. It is a fully composable toolkit:

• affinity mirage: Launch the full-screen interactive IDE mode! Browse files, vim-edit inline, and cleanly copy code over SSH natively using our zero-artifact dual-buffer engine.
• affinity watch script.py: Watches the file and instantly re-renders the syntax highlighting every time you save.
• affinity diff old.py new.py: A stunning side-by-side/unified terminal diff viewer.
• affinity run script.py: Executes the python script inline, presenting stdout and exit codes elegantly below the syntax-highlighted source.
• Piping Support: Native stdin support means cat log.txt | affinity automatically syntax-highlights the piped stream!

✨ Spectacular Features

💻 Installation

Affinity is officially published on PyPI and can be installed globally with a single command!

Python Package Index (Recommended)

To install Affinity across your entire system, simply run:

pip install affinity-code-viewer

Install from Source

If you prefer to install from source without messing with system environments, clone this repository and run the startup script. It bypasses environment headaches and securely installs the package exclusively for your local user.

git clone https://github.com/your-username/affinity.git
cd affinity
./start.sh

Note: The script will automatically add ~/.local/bin to your PATH if it isn't already there!

Uninstallation

To cleanly wipe Affinity and all its artifacts from your system:

# Remove Affinity and clean up build artifacts
./remove.sh

🛠️ CLI Usage

Affinity was designed with an intuitive, human-first command-line interface.

# 📖 Basic File Viewing
affinity main.py

# 🌲 View an entire directory tree
affinity src/

# 🧛 Use a specific color theme
affinity main.py --theme dracula

# 🔍 Highlight search terms in the file
affinity config.yaml --search "database"

# 🎯 Highlight a specific line
affinity server.rs --line 145

# 🚫 Disable all formatting (acts like standard 'cat')
affinity data.txt --plain

# ℹ️ View all available CLI options
affinity --help

⚙️ Configuration

Tired of passing the --theme flag every time? Affinity supports permanent user configuration.

Simply create a file at ~/.config/affinity/config.toml:

# Default configuration
theme = "dracula"
line_numbers = true
wrap = true
scope_guides = true

🧬 Architecture

Affinity achieves its stunning visuals by bridging Pygments (for robust token lexing) and Rich (for terminal ANSI rendering).

Unlike standard bat, Affinity intercepts the token stream and injects calculated │ characters at precise indentation boundaries by reading mathematical spaces, ensuring that syntax colors (spans) are perfectly preserved even when slicing text arrays on the fly.

❓ FAQ

Q: Does Affinity support binary files?
A: Yes! Affinity detects binary signatures automatically and gracefully prevents terminal garbage output.

Q: Why not just use bat?
A: bat is incredible, but Affinity goes a step further by natively rendering VS Code-like vertical indentation guides. This makes reading heavily nested Python or YAML files infinitely easier in the terminal.
