# 🔹 scot
# Wrapper for CotEditor's bundled CLI.
# Opens files in a new CotEditor window and waits until that window closes.
# Behaves like a lightweight "cot -w -n" helper without creating a symlink.
# Example:
#   % scot file.txt
#   (opens file.txt in a new CotEditor window and waits)

# 🔹 smbname2ip
# Resolve an SMB machine name to its IP address.
# Example:
#   % smbname2ip myserver
#   192.168.1.42

}

# 🔹 brewdump
# Print the current Homebrew bundle (list of installed packages, casks, and taps)
# directly to standard output instead of saving it to a file.
#
# Example:
#   % brewdump
#   tap "homebrew/core"
#   brew "git"
#   cask "visual-studio-code"
#
# Equivalent to: brew bundle dump --file=/dev/stdout
function brewdump() {

# 🔹 peek
# Show stdin on the current terminal while passing it through unchanged.
# Useful for checking piped output without interrupting the pipeline.
# Example:
#   % mycli | peek | pbcopy
function peek() {
    tee /dev/tty
}

# Compare two list files and show additions (+) and deletions (-) with colors
# Usage:
#   % listdiff old.txt new.txt [--added] [--removed] [--print]
# Examples:
#   % listdiff Brewfile <(brewdump)
#   % listdiff Brewfile <(brewdump) --added
#   % listdiff Brewfile <(brewdump) --removed --print
