Please help me write a command line application for changing macOS system appearance (between light and dark mode) called 'appear'. Though it will be simple, I would like the application itself it to be as comprehensive as possible - so a help page and man page with automatic installation on macos should be included - along with anything else needed to make it ready for package managers. Ideally, I would like to publish it to Homebrew, but - as I think it should be based in Ruby - please hold off on that and instead help me publish it as a Ruby gem. ### For light mode To change the system appearance to light mode, the user runs the command `appear light` Our command line application uses this Applescript command to accomplish this: `osascript -e 'tell app "System Events" to tell appearance preferences to set dark mode to false'` ### For dark mode To change the system appearance to light mode, the user runs the command `appear dark` Our command line application uses this Applescript command to accomplish this: `osascript -e 'tell app "System Events" to tell appearance preferences to set dark mode to true'`

Here’s a comprehensive plan to develop the command line application appear for switching macOS system appearance between light and dark mode. The plan covers writing the script, creating a help page and man page, and packaging the application as a Ruby gem for future distribution via Homebrew or RubyGems.

Step 1: Write the Command Line Application in Ruby

We'll begin by writing the Ruby script that toggles between light and dark mode using AppleScript.

#!/usr/bin/env ruby

require 'optparse'

class Appear
  def self.change_mode(mode)
    if mode == 'light'
      system("osascript -e 'tell app \"System Events\" to tell appearance preferences to set dark mode to false'")
      puts 'System appearance changed to light mode.'
    elsif mode == 'dark'
      system("osascript -e 'tell app \"System Events\" to tell appearance preferences to set dark mode to true'")
      puts 'System appearance changed to dark mode.'
    else
      puts 'Invalid mode. Use `light` or `dark`.'
    end
  end
end

# Parse command-line arguments
options = {}
OptionParser.new do |opts|
  opts.banner = "Usage: appear [options]"

  opts.on('-h', '--help', 'Display help') do
    puts opts
    exit
  end

  opts.on('light', 'Change system appearance to light mode') do
    Appear.change_mode('light')
  end

  opts.on('dark', 'Change system appearance to dark mode') do
    Appear.change_mode('dark')
  end
end.parse!

if ARGV.empty?
  puts 'No mode specified. Use `light` or `dark`.'
else
  Appear.change_mode(ARGV[0])
end

Step 2: Add a Help Page

The OptionParser in Ruby handles help automatically when the user passes the --help flag. However, we can improve the help output by adding descriptions and formatting.

opts.banner = "Usage: appear [light|dark] [options]"
opts.separator ""
opts.separator "Specific options:"
opts.separator "  light        Switch system appearance to light mode"
opts.separator "  dark         Switch system appearance to dark mode"
opts.separator ""
opts.separator "Common options:"

Step 3: Create a Man Page

You can create a simple man page for appear using the groff format. Here is a basic man page that can be installed on macOS:

Save the following content in a file called appear.1.

.TH APPEAR 1 "2024" "appear 1.0" "User Commands"
.SH NAME
appear \- change macOS system appearance between light and dark mode
.SH SYNOPSIS
.B appear
[\fIlight|dark\fR]
.SH DESCRIPTION
The \fBappear\fR command changes the macOS system appearance between light and dark mode.

Use the command with one of the following arguments:
.TP
\fBlight\fR
Switch system appearance to light mode.
.TP
\fBdark\fR
Switch system appearance to dark mode.

.SH OPTIONS
.TP
\fB-h\fR, \fB--help\fR
Display this help message.
.SH AUTHOR
David Blue

Step 4: Automate Installation

Create a Rakefile to handle installation steps. The following Rakefile installs the appear binary and the man page:

require 'rake/clean'

CLEAN.include('appear.o')

desc 'Install the appear script'
task :install do
  sh 'cp appear /usr/local/bin/appear'
  sh 'chmod +x /usr/local/bin/appear'
  sh 'mkdir -p /usr/local/share/man/man1'
  sh 'cp appear.1 /usr/local/share/man/man1/appear.1'
end

desc 'Uninstall appear'
task :uninstall do
  sh 'rm /usr/local/bin/appear'
  sh 'rm /usr/local/share/man/man1/appear.1'
end

Step 5: Package the Application as a Ruby Gem

To package appear as a Ruby gem, you’ll need to create a gemspec file that defines the gem’s metadata and dependencies.

Create a file called appear.gemspec:

Gem::Specification.new do |spec|
  spec.name          = "appear"
  spec.version       = "1.0.0"
  spec.authors       = ["David Blue"]
  spec.email         = ["your-email@example.com"]
  
  spec.summary       = %q{A command line tool to change macOS system appearance between light and dark mode.}
  spec.description   = %q{A simple command line tool that allows users to switch between light and dark modes on macOS by running a command.}
  spec.homepage      = "https://example.com/appear"
  
  spec.files         = ["lib/appear.rb", "bin/appear", "appear.gemspec", "Rakefile", "LICENSE.txt", "README.md"]
  spec.bindir        = "bin"
  spec.executables   = ["appear"]
  
  spec.required_ruby_version = '>= 2.3.0'
  
  spec.metadata["allowed_push_host"] = "https://rubygems.org"
end

Ensure you have the necessary files like LICENSE.txt and README.md in the same directory as your gemspec.

Step 6: Build and Publish the Gem

Once the gemspec file is ready, build the gem:

gem build appear.gemspec

This will create a .gem file. You can now push it to RubyGems:

gem push appear-1.0.0.gem

Step 7: Future Steps for Homebrew

When you're ready to publish it on Homebrew, you can create a formula and submit it to the Homebrew repository. However, focusing on the Ruby gem allows you to package it for any Ruby-based environment first.

Summary

You now have a full-fledged macOS command-line application that:

Toggles system appearance between light and dark mode.
Provides a detailed help page.
Includes a man page.
Is packaged as a Ruby gem, ready to be published to RubyGems.

Let me know if you need further assistance with any step!

12:12

Before I do anything, I think I'm going to go ahead and initialize a repository for all of this. Can you show me how these files should be organized in said repository?

12:14

Here’s how you should organize your repository for the appear project. I'll structure it in a way that makes it easy to maintain and distribute as a Ruby gem:

appear/
├── bin/
│   └── appear                 # The main executable script
├── lib/
│   └── appear.rb              # Ruby file with the core logic
├── man/
│   └── appear.1               # The man page
├── spec/                      # (Optional) Tests, if you plan to add any
├── Rakefile                   # Rake tasks for installation/uninstallation
├── appear.gemspec             # Gem specification file
├── LICENSE.txt                # License information
├── README.md                  # Project documentation
└── .gitignore                 # Git ignore file for unnecessary files

File Structure Details

bin/appear: This is the main executable for your command-line application. It will be a small Ruby script that invokes the code in lib/appear.rb.
lib/appear.rb: The core logic of your application resides here. You want to separate your logic into the lib folder to keep the binary (bin/appear) lightweight and to follow common Ruby practices.
man/appear.1: The man page is stored in its own directory. This can be installed in /usr/local/share/man/man1 on the user’s system as part of your Rakefile or installation process.
spec/: This is optional, but if you want to write tests for your gem, they would go here. You can use RSpec or Minitest if you decide to implement unit tests later.
Rakefile: Handles installation and uninstallation tasks for the script and the man page.
appear.gemspec: The gemspec file contains metadata and other details for packaging and publishing the Ruby gem.
LICENSE.txt: Add a suitable license for your project here, such as MIT, GPL, etc.
README.md: Documentation about the project, including installation instructions, usage examples, and any other details.
.gitignore: Specify files and directories that Git should ignore, such as:
```
*.gem
*.log
.DS_Store
.bundle/
```

Example Files

bin/appear:

#!/usr/bin/env ruby
require_relative '../lib/appear'
Appear.run(ARGV)

lib/appear.rb:

require 'optparse'

class Appear
  def self.run(args)
    options = {}
    OptionParser.new do |opts|
      opts.banner = "Usage: appear [light|dark]"

      opts.on('-h', '--help', 'Display this help') do
        puts opts
        exit
      end
    end.parse!(args)

    mode = args[0]
    case mode
    when 'light'
      system("osascript -e 'tell app \"System Events\" to tell appearance preferences to set dark mode to false'")
      puts 'System appearance changed to light mode.'
    when 'dark'
      system("osascript -e 'tell app \"System Events\" to tell appearance preferences to set dark mode to true'")
      puts 'System appearance changed to dark mode.'
    else
      puts 'Invalid mode. Use `light` or `dark`.'
    end
  end
end

Initialization with Git and Bundler

Once you have these files in place, initialize a git repository:

git init
git add .
git commit -m "Initial commit"

You can also use Bundler to manage gem dependencies and versioning:

bundle init

This creates a Gemfile in the project, where you can add any necessary gems.

Once the repository is initialized and files are in place, you’re ready to build, test, and later push your Ruby gem.

Let me know if you'd like to add anything else!

12:15

Would you go ahead and provide me with the exact contents of each file in the tree you provided above?

12:18

Certainly! Here’s the exact content for each file that you can use to initialize your appear project.

Project Directory Structure

└── .gitignore

1. `bin/appear`

#!/usr/bin/env ruby
require_relative '../lib/appear'

# Run the command with arguments
Appear.run(ARGV)

This file calls the main logic defined in lib/appear.rb. It simply passes the command-line arguments to the Appear class.

2. `lib/appear.rb`

require 'optparse'

class Appear
  def self.run(args)
    options = {}
    OptionParser.new do |opts|
      opts.banner = "Usage: appear [light|dark]"

      opts.on('-h', '--help', 'Display this help') do
        puts opts
        exit
      end
    end.parse!(args)

    mode = args[0]
    case mode
    when 'light'
      system("osascript -e 'tell app \"System Events\" to tell appearance preferences to set dark mode to false'")
      puts 'System appearance changed to light mode.'
    when 'dark'
      system("osascript -e 'tell app \"System Events\" to tell appearance preferences to set dark mode to true'")
      puts 'System appearance changed to dark mode.'
    else
      puts 'Invalid mode. Use `light` or `dark`.'
    end
  end
end

This file contains the main logic for the appear application, parsing the mode (light or dark) and running the corresponding AppleScript command.

### 9. `.gitignore`

```txt
*.gem
*.log
.DS_Store
.bundle/

This .gitignore file excludes unnecessary files like .gem builds, logs, macOS .DS_Store files, and the Bundler .bundle directory.

Summary

With these files in place and structured as outlined, you’re ready to initialize the project and begin working with your command-line tool. You can follow these steps to set it up:

Initialize the repository:
```
git init
```

Add all files and commit:

git add .
git commit -m "Initial commit"

Build and install the gem when ready:
```
rake install
```

Let me know if you'd like to modify or add anything further!

12:18

Having followed said steps, I'm receiving the following on my mac when I just tried to run both `appear dark` and `appear light`: /usr/local/bin/appear:2:in `require_relative': cannot load such file -- /usr/local/lib/appear (LoadError) from /usr/local/bin/appear:2:in `<main>'

12:31

The error message you're receiving suggests that the require_relative in your bin/appear script is looking for the appear.rb file in the wrong location after the install process. Specifically, it's looking for lib/appear.rb in /usr/local/lib/ instead of in your project's lib/ directory.

To resolve this, you need to adjust the require_relative path in the bin/appear file so that it properly points to the lib directory during execution.

Steps to Fix

Modify the bin/appear script to handle the correct lib path: The bin/appear script needs to dynamically figure out where the lib/appear.rb file is located relative to its own location. Here's how you can update it:

Update `bin/appear`:

#!/usr/bin/env ruby

# Determine the absolute path of the lib/appear.rb file
$LOAD_PATH.unshift(File.expand_path('../../lib', __FILE__))

require 'appear'

# Run the command with arguments
Appear.run(ARGV)

Explanation:

File.expand_path('../../lib', __FILE__) calculates the absolute path of the lib folder relative to where the bin/appear script is located.
$LOAD_PATH.unshift(...) adds the lib directory to the Ruby load path, allowing require 'appear' to find lib/appear.rb.

Reinstall

After making this change, you'll need to reinstall the appear script:

rake uninstall  # Uninstall the current version
rake install    # Reinstall the script

Now, try running appear light or appear dark again, and the error should be resolved.

Let me know how it goes!

12:31

Why don't we go ahead and publish this as a ruby gem? It seems like installing via gem might fix some of these errors.

12:34

Publishing the appear project as a Ruby gem is a great idea! It will make installation and usage more reliable, as RubyGems will handle the dependencies, installation paths, and executable generation for you. Let’s walk through the steps to publish it as a Ruby gem.

Step-by-Step Process for Publishing `appear` as a Ruby Gem

1. Ensure `appear.gemspec` is Correct

The gemspec file contains all the metadata about your gem, including the files to package and publish.

Here’s the appear.gemspec file again, with a few small improvements:

Gem::Specification.new do |spec|
  spec.name          = "appear"
  spec.version       = "1.0.0"
  spec.authors       = ["David Blue"]
  spec.email         = ["your-email@example.com"]
  
  spec.summary       = %q{A command line tool to change macOS system appearance between light and dark mode.}
  spec.description   = %q{A simple command line tool that allows users to switch between light and dark modes on macOS by running a command.}
  spec.homepage      = "https://github.com/username/appear"
  spec.license       = "MIT"

  spec.files         = Dir["lib/**/*.rb"] + ["bin/appear", "man/appear.1", "Rakefile", "LICENSE.txt", "README.md"]
  spec.bindir        = "bin"
  spec.executables   = ["appear"]
  spec.require_paths = ["lib"]

  spec.required_ruby_version = '>= 2.3.0'
  spec.metadata["allowed_push_host"] = "https://rubygems.org"
end

Make sure to replace "your-email@example.com" and "https://github.com/username/appear" with your actual email and GitHub repository URL.

2. Build the Gem

You can use Bundler to build the gem. First, ensure your environment is properly set up:

bundle install

Now, build the gem:

gem build appear.gemspec

This command will generate a .gem file, such as appear-1.0.0.gem, in the current directory.

3. Sign Up for RubyGems.org (If You Haven't Already)

If you don’t have a RubyGems.org account yet, create one by going to RubyGems.org.

4. Push the Gem to RubyGems.org

First, you’ll need to authenticate your local system with RubyGems. Run the following command and enter your RubyGems credentials when prompted:

gem signin

Once signed in, push the gem:

gem push appear-1.0.0.gem

This will upload your gem to RubyGems.org and make it available for everyone to install.

5. Install the Gem Locally

After publishing the gem, you can test it locally to make sure everything works as expected:

gem install appear

Now, the appear command should work properly without needing to manage installation paths manually.

Example Workflow After Publishing

Install the Gem:
```
gem install appear
```

Use the Commands:

appear light   # Switches macOS to light mode
appear dark    # Switches macOS to dark mode

Uninstall:

If you ever need to uninstall the gem, use:
```
gem uninstall appear
```

Next Steps

GitHub Repository: Consider creating a GitHub repository for your project (if you haven’t already). This will allow people to contribute, file issues, and review your code. Include the repository URL in the gemspec file's homepage field.
Continuous Integration (CI): You can set up CI tools like GitHub Actions or Travis CI to automatically run tests or build the gem when you push changes to GitHub.
Versioning: For future updates, remember to increment the version number in appear.gemspec (e.g., "1.0.1").

Let me know if you run into any issues, and I can help you troubleshoot further!

12:34

I got a warning after building noting that bin/appear is not executable

12:42

The warning you received is related to file permissions for the bin/appear script. Ruby expects the scripts in the bin/ directory to be executable, but in this case, the file likely doesn't have the correct permissions.

Fixing the Executable Permission for `bin/appear`

To resolve this, you need to make the bin/appear file executable by setting the correct file permissions. Here’s how to do that:

Set the Executable Permission:

Run the following command in your project directory:
```
chmod +x bin/appear
```
This will set the executable flag on the bin/appear script, allowing it to be run as an executable.
Rebuild the Gem:

After making the script executable, you should rebuild the gem:
```
gem build appear.gemspec
```
Check if the Warning Is Gone:

Now, the warning about the script not being executable should disappear. You can test this by installing the gem locally or pushing it to RubyGems.

Confirm Permissions

You can confirm that the file is executable by running the following command:

ls -l bin/appear

The output should look something like this:

-rwxr-xr-x  1 user  group  1234 Sep 17 15:00 bin/appear

The x indicates that the file is executable.

Re-Publish the Gem

If the permissions are now correct, you can follow the steps to push the updated gem to RubyGems:

gem push appear-1.0.0.gem

Let me know how it goes!
