pfzf

Interactively generate structured context files from your codebase, designed for LLM pair programming workflows.

Kind of inspired by fzf. I put 0 effort in, not responsible for anything.

⚠️ Alpha Status: This project is in early development, written mostly with Claude because I was lazy and needed this quickly. APIs and features may change significantly.

Features (if you want to even call them that)

• Interactive file preview and selection with fuzzy search
• Fast and memory-efficient processing
• Multiple output formats (XML, JSON, YAML)
• Terminal UI with customizable themes (sort of works lol)

Installation

go install github.com/lc/pfzf@latest

Quick Start

# Basic usage (outputs to pfzf_*.xml by default)
pfzf

# Specify output format
pfzf -format json

# Use custom config file
pfzf -config ~/.config/pfzf/config.json

Configuration

pfzf can be configured via a JSON configuration file located at $HOME/.pfzf/config.json

You can specify a custom config location using the -config flag:

Note: a lot of the keys are not implemented yet, but they are there for future use.

pfzf -config /path/to/config.json

    "ignorePatterns": [".git", "node_modules"],

      "quit": "q",
      "select": "space",
      "toggle_preview": "p",
      "help": "?",
      "focus_search": "/",
      "clear_search": "esc"
    }
  }
}

Key Bindings

• Space: Select/deselect file
• ↑/↓: Navigate files
• /: Focus search
• ESC: Clear search
• p: Toggle preview
• q: Quit
• ?: Show help

Output Formats

pfzf supports three output formats:

• XML (default)
• JSON
• YAML

Each format includes:

• Directory context (current working directory and tree structure)
• Selected file contents with metadata
• Language-specific processing results (when enabled)

Development Status

This is an alpha release. While the core functionality is working, you may encounter:

• API changes
• Feature additions/removals
• Performance optimizations
• Bug fixes
