+## Usage

+
+- `copypath <file_or_directory>`: copies the absolute path of the given file.

plugins/copypath/copypath.plugin.zsh

+# Copies the path of given directory or file to the system or X Windows clipboard.
+# Copy current directory if no parameter.
+function copypath {
+  # If no argument passed, use current directory
+  local file="${1:-.}"
+
+  # If argument is not an absolute path, prepend $PWD
+  [[ $file = /* ]] || file="$PWD/$file"
+
+  # Copy the absolute path without resolving symlinks
+  # If clipcopy fails, exit the function with an error
+  print -n "${file:a}" | clipcopy || return 1
+
+  echo ${(%):-"%B${file:a}%b copied to clipboard."}
+}
