Its purpose is to simplify the installation for smooth and effortless start. To execute this script, kindly adhere to the following instructions:

1. Open the terminal and run the installation command: make -f Makefile i
2. Open the terminal and run the updating command: make -f Makefile u

Sit back, relax, and enjoy the seamless experience!

P.S. You have the flexibility to configure the install_packages section according to your specific application needs

1. Setting up the shell and path:

   • The SHELL variable is set to /bin/bash, indicating that the default shell used in the script is Bash.
   • The PATH variable is updated to include the /usr/local/bin directory, ensuring that executables in that directory are accessible.

2. Defining variables:

   • The ruby_version variable stores the latest Ruby version available from rbenv install -l | grep -v - | tail -1.
   • The current_ruby_version variable stores the currently installed Ruby version from rbenv version | awk '{print $$1}'.

3. Rule: xcode:

   • The target xcode checks if the xcodebuild command is available.
   • If xcodebuild is not found, it prompts the user to install Xcode and waits until xcodebuild is available.

4. Rule: homebrew:

   • The target homebrew checks if the brew command is available.
   • If brew is not found, it installs Homebrew by executing the installation script retrieved from the official Homebrew repository.

5. Rule: rbenv:

   • The target rbenv checks if the rbenv command is available.
   • If rbenv is not found, it installs rbenv using Homebrew and adds the necessary configuration to the ~/.bash_profile file to initialize rbenv in the shell.

6. Rule: ruby:

   • The target ruby compares the latest Ruby version (ruby_version) with the current Ruby version (current_ruby_version).
   • If they are different, it installs the latest Ruby version using rbenv install and sets it as the global version using rbenv global.
   • After installing Ruby, it runs rbenv rehash to update the Ruby environment.

7. Rule: bundler:

   • The target bundler checks if the bundler command is available.
   • If bundler is not found, it installs Bundler gem using gem install --user-install bundler and performs rbenv rehash to update the Ruby environment.

8. Rule: create_folder:

   • The target create_folder checks if the ~/Developer folder exists.
   • If the folder does not exist, it creates it using sudo mkdir -p ~/Developer.

9. Rule: packages_install:

   • The target packages_install installs various packages and applications using Homebrew (brew).
   • It installs packages like cocoapods, fastlane, rbenv-bundler, and applications like iterm2, slack, figma, fork, and telegram using the brew install command.

10. Rule: rectangle:

    • The target package_install_rectangle prompts the user to choose between installing Rectangle or Rectangle Pro.
    • The user's choice is stored in the answer variable using the read command.
    • Depending on the user's choice, it installs the corresponding package (rectangle or rectangle-pro) using brew install --cask.

11. Rule: packages_update:

    • The target packages_update upgrades the installed packages and applications to their latest versions using brew upgrade.
    • It upgrades packages like cocoapods, fastlane, rbenv-bundler, and applications like `iterm2

, slack, figma, fork, and telegram. - Additionally, if either rectangleorrectangle-pro` is already installed, it upgrades the corresponding package.

12. Rule: powerlevel10k:

    • The target powerlevel10k checks if the ~/.powerlevel10k folder exists.
    • If the folder does not exist, it clones the Powerlevel10k theme repository from GitHub using git clone.
    • It also adds the necessary configuration to the ~/.zshrc file to enable the Powerlevel10k theme.

13. Rule: open_iterm2:

    • The target open_iterm2 opens the iTerm2 application using the open -a iTerm command.

14. PHONY section:

    • The .PHONY section lists all the targets that are not associated with actual files.
    • It ensures that these targets are always executed, regardless of whether a file with a matching name exists or not.

15. Targets: install and update:

    • The install target sets up the development environment by executing the necessary rules in a specific order.
    • It includes targets like xcode, homebrew, rbenv, ruby, bundler, create_folder, rectangle, packages_install, powerlevel10k, and open_iterm2.
    • The update target updates the development environment by upgrading rbenv, ruby, and installed packages using the packages_update rule.
