Summary of Changes

Hello @thelovekesh, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the user experience and functionality of the install command by introducing intelligent checks to prevent unnecessary operations and providing clearer feedback. It also expands the wpm.json configuration capabilities, allowing for more detailed dependency management and project-specific settings. These changes aim to make the package manager more robust and user-friendly, particularly for new projects or when managing complex dependency trees.

Highlights

• Improved Install Command User Experience: The install command now includes checks to bail out early if no wpm.json file is found (when no specific packages are provided) or if there are no packages (dependencies or dev dependencies) specified in the wpm.json to install, providing clearer feedback to the user.
• Expanded install Command Documentation: The README.md has been updated to include comprehensive documentation for the install command, detailing new flags such as --no-dev, --ignore-scripts, --dry-run, --save-dev, --save-prod, and --network-concurrency.
• Enhanced wpm.json Configuration: The wpm.json example and documentation have been extended to support requires (minimum requirements), devDependencies, and a config section with options like bin-dir, content-dir, runtime-wp, runtime-php, and runtime-strict.
• Internal Refactoring for Default Configurations: The wpmjson package underwent refactoring, renaming an internal field from packageConfig to defaultPackageConfig and moving its initialization to the Read() function. This ensures default package configurations are consistently applied when a wpm.json file is loaded.

Code Review

This pull request improves the user experience of the install command by adding a check to exit early if there are no packages to install, which is a great addition. The documentation updates in the README are also very helpful. I've identified a few areas for improvement, including a case of code duplication that should be refactored, a minor regression in the command-line help text, and an inconsistency in the code examples in the documentation. My detailed feedback is in the comments below.

Code Review

This pull request enhances the install command's user experience by adding new options, examples, and aliases. It also improves the command's behavior by gracefully handling cases where no packages need to be installed. The documentation in README.md has been updated to reflect these changes. Additionally, there's a nice refactoring of the default package configuration handling, which also fixes a potential bug where default values were not being applied correctly when a wpm.json file was read from disk. My review includes suggestions to improve documentation consistency and to replace a magic string with a more idiomatic Go sentinel error.
