Ancillary bash/zsh function to use `ksdiff` (or `diff`, or `opendiff` on the Mac) to compare files

diff_str_functions.sh

ksdiffstr () {
  ksdiff    <(echo "$1") <(echo "$2") # Comment or uncomment to use the desired tool
}

diffstr () {
  diff     <(echo "$1") <(echo "$2") # Comment or uncomment to use the desired tool
}

opendiffstr () {
  # Process substitution does not work with opendiff
  # Hence, we use `mktemp` to create a couple of temporary files
  temp_file_1=$(mktemp -t "$0.txt") || exit 1
  echo "$1" > "$temp_file_1"
  temp_file_2=$(mktemp -t "$0.txt") || exit 1
  echo "$2" > "$temp_file_2"
  opendiff "$temp_file_1" "$temp_file_2"
