Clipboard Manager (cb)

Description

A versatile command-line utility for copying file contents, directory contents, or STDIN input to the system clipboard. Supports both text and image files, with special features for Discord formatting and debug output. The command is installed as cb and maps to copybuffer.main:main, so it can also be invoked with python -m copybuffer.

Features

• Copy text from files to clipboard
• Copy text from STDIN to clipboard
• Copy contents of all files in a directory
• Copy images to clipboard
• Include headers with filenames
• Format output for Discord
• Generate heredoc shell script to recreate files on paste
• Append mode for heredoc script generation
• Verbose output option
• Debug mode

Requirements

• Python 3.x

• pyperclip

• PIL (for image support)

• xclip or xsel (Linux only, requires an X11 DISPLAY)

• wl-clipboard (Wayland only)

  On CachyOS/Hyprland systems, wl-clipboard is required. Wayland detection checks for WAYLAND_DISPLAY, XDG_SESSION_TYPE=wayland, HYPRLAND_INSTANCE_SIGNATURE, or SWAYSOCK.

Installation

1. Install package with pipx:

pipx install .

Uninstall

pipx uninstall copybuffer)

2. For Linux systems, install clipboard handlers:

sudo apt-get install xclip
# or
sudo apt-get install xsel
# For Wayland sessions
sudo apt-get install wl-clipboard

Usage

Basic Usage

# Copy file contents
cb filename.txt

# Copy from STDIN
echo "hello" | cb

# Copy directory contents
cb -d directory/

# Copy with Discord formatting
cb -a filename.txt

# Copy with headers
cb -i filename.txt

# Copy as heredoc script for recreating files on paste
cb -p path/to/file1.txt path/to/file2.txt

# Copy as heredoc script that appends to target files
cb --append path/to/file1.txt

Options

• file: File to copy (optional - reads from STDIN if not provided)
• -i, --include-header: Include filename as header in copied text
• -d, --directory: Copy contents of all files in directory
• -v, --verbose: Display the copied contents
• -a, --attachment: Format output as Discord attachment
• -p, --paste: Copy a heredoc shell script that recreates the given files when pasted
• --append: Use with --paste behavior to append to files instead of overwriting
• --image: Force treating input files as images (images are auto-detected)
• --debug: Enable debug mode
• --version: Display application version

Image Support

Supports copying image files directly to clipboard. Image files are detected automatically based on their MIME type, or you can force image handling with the --image flag:

• PNG
• JPG/JPEG
• BMP
• GIF (first frame)

cb image.png

Directory Mode

Copy contents of all text files in a directory:

cb -d /path/to/directory

• Automatically skips image files
• Optionally includes headers with -i flag
• Can format as Discord attachments with -a flag

Debug Mode

Enable detailed output for troubleshooting:

cb --debug filename.txt

Version Information

# Display version information
cb --version
# Output: copybuffer version 1.8.0

Error Handling

The script provides clear error messages for common issues:

• Missing dependencies
• File not found
• Permission errors
• Invalid file types
• Directory access errors

Examples

Copy with Headers

cb -i document.txt
# Output includes: === document.txt ===

Discord Formatting

cb -a code.py
# Output format: [Attached file: code.py\nContent:\n```\n...\n```\n]

Heredoc Script Generation

# Overwrite or create files on the target system
cb -p path/to/file1 path/to/nested/dir/file2

# Append to files on the target system
cb --append path/to/file1

# Notes:
# - A random, content-safe delimiter is used to avoid collisions
# - Single-quoted heredocs prevent shell interpolation

Verbose Directory Copy

cb -d -v -i /path/to/docs
# Shows all processed files and copied content

Troubleshooting

If you encounter issues:

1. Check dependencies with --debug flag
2. Verify clipboard system access
3. Check file permissions
4. Ensure proper Python version
