🔑 Key Interfaces

type Store interface {
    List() ([]*Template, error)
    Get(name string) (*Template, error)
    Save(tmpl *Template) error
    Delete(name string) error
    Exists(name string) bool
}

type ContextProvider interface {
    GetProjectName() string
    GetLanguage() string
    GetFramework() string
    GetCurrentFile() string
    GetSelection() string
}

🛡️ Error Handling

var (
    ErrTemplateNotFound = errors.New("template: not found")
    ErrTemplateExists   = errors.New("template: already exists")
    ErrInvalidTemplate = errors.New("template: invalid")
    ErrBuiltInTemplate = errors.New("template: cannot modify built-in")
)

✨ Features

  • Variable expansion - {{variable}} syntax with context auto-population
  • File persistence - JSON files in ~/.gvshell/templates/
  • Thread-safe caching - sync.RWMutex for concurrent access
  • Built-in protection - Cannot modify/delete built-in templates
  • FileSystem abstraction - Interface for testing without real filesystem
  • Command alias - /tpl as shorthand for /template
