Undo frameworks built by Carthage except the one given framework

undo_ios_carthage_except.sh

#!/bin/sh

#
# Script for Xcode and Carthage
# ------------------------------
#
# Dismisses changes to all the frameworks except the given frameworks in the iOS build folder.
# This is used to undo the changes done to the framework build after `carthage update` command.
#
#
# Usage
# ------
#
# For example, undo changes to all frameworks except KIF and Quick.
# This is executed from the root Xcode project folder:
#
#    ./undo_ios_carthage_except.sh kif quick
#
#  The supplied framework names:
#     1. Are case insensitive.
#     2. Can be partial: "http" will keep OHHTTPStubs framework.
#

# Make string comparison case insensitive
shopt -s nocaseglob

# Check if arguments are correct
# ------------

if [ "$#" -lt 1 ]
then
  echo "\nUsage:\n"
  echo "   ./undo_carthage_except.sh name name name\n"
  exit 1
fi

git checkout Carthage/Build/Mac --force

# Go through all iOS framework folders
# ------------

for framework in `find Carthage/Build/iOS -iname *.framework`;
do

  keep=false

  # Check if arguments match the framework path
  # ------------

  for arg
  do
    exception=${arg[$i]}

    if [[ $framework =~ $exception ]]
    then
      keep=true
    fi

  done;

  # Keep or dismiss the framework changes
  # ------------

  if [ "$keep" = true ] ; then
    echo "---- KEEP $framework ----"
  else
    git checkout "$framework" --force
    echo "Undo $framework"
  fi
done;

echo "\n🐌  🐝  🐸"

# Make string comparison case sensitive
