SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill enables the creation of optional, conditional functionality for Julia packages through package extensions, improving modularity and reducing load times for users who don't need specific features.

Core Features & Use Cases

Optional Functionality: Add features that are only loaded when a specific "trigger" package is imported.
Dependency Management: Properly declare and manage weak dependencies for extensions.
Use Case: Imagine you have a plotting package. You can create a MakieExt.jl that adds plotting capabilities only if the user has Makie.jl installed, keeping your core package lean.

Quick Start

Use the julia-pkgextension skill to add Makie.jl as a weak dependency for your package.

FAQPage Schema

What are Julia package extensions and how do weak dependencies work?▼

Julia package extensions provide optional, conditional functionality by using weak dependencies that only load features when a specific trigger package is imported, keeping the core package lean. This improves modularity and reduces load times for users who do not need those specific features.

How do I add optional plotting functionality to my Julia package without increasing load times?▼

You can add a weak dependency like Makie.jl to your package and create an extension module. This conditionally loads plotting capabilities only when the user imports the trigger package, ensuring your core package remains lightweight and fast to load.

How do I structure and load a conditional extension module in Julia?▼

You structure the extension module within your package and leverage weak dependencies for programmatic loading. The extension is automatically triggered and loaded when the user imports the specific dependent package, integrating seamlessly with your existing workflows.

Can I integrate Julia package extensions with testing and documentation workflows?▼

Yes, building Julia package extensions supports integration with documentation and testing workflows. This ensures your conditionally loaded modules and optional functionality are properly tested and documented alongside your core package development process.

When should I use conditional loading for Julia packages instead of regular dependencies?▼

You should use conditional loading with weak dependencies when you want to provide optional functionality that only certain users need. This prevents forcing all users to install heavy dependencies and significantly reduces package load times for those who do not use the extensions.
