Clap slaps all your files into one!

A blazingly fast CLI tool that combines multiple files from a directory into a single, organized output file. Perfect for sharing codebases with LLMs, conducting code reviews, or creating comprehensive documentation snapshots.

• 🚀 Fast & Efficient - Recursively walks through directories at lightning speed
• 🎯 Smart Filtering - Filter files by extension (supports multiple extensions)
• 📝 Clear Formatting - Each file is clearly separated with headers showing the file path
• 💪 Flexible Output - Customize the output filename to your needs
• 🔄 Case-Insensitive - Extensions work with or without dots (.go or go)
• 📊 Progress Tracking - See which files are being processed with size information
• 🌳 Recursive Search - Automatically traverses nested directories

go install github.com/yourusername/clap@latest

Or build from source:

git clone https://github.com/yourusername/clap.git
cd clap
go build

Combine all files in a directory:

clap /path/to/directory

Combine only specific file types:

# Single extension
clap /path/to/project .go

# Multiple extensions
clap /path/to/project .go .md .txt

# Extensions work without dots too!
clap /path/to/project go md txt

Specify a custom output filename:

clap -o combined.txt /path/to/directory .js .ts

Combine all Go files in a project:

clap ./myproject .go

Create a codebase snapshot for AI:

clap -o context.txt ./src .js .jsx .ts .tsx

Gather all documentation:

clap -o all-docs.md ./docs .md

Clap creates a well-organized output file with clear separators:

=== path/to/file1.go ===
[file content]

=== path/to/file2.go ===
[file content]

• AI Context Building - Feed entire codebases to Large Language Models
• Code Reviews - Share complete project snapshots
