Function New

pkg/cache/cache.go:87–106

New builds a Cache from the given Config. It returns (nil, nil) when caching is disabled, allowing callers to short-circuit with a simple nil check.

(cfg Config)

// caching is disabled, allowing callers to short-circuit with a simple
// nil check.
func New(cfg Config) (*Cache, error) {
	if !cfg.Enabled {
		return nil, nil //nolint:nilnil // intentional: nil signals caching disabled
	}

	c := &Cache{
		entries:   make(map[string]string),
		normalize: keyNormalizer(cfg.CaseSensitive, cfg.TrimSpaces),
		path:      cfg.Path,
	}

	if cfg.Path != "" {
		if err := loadFromFile(cfg.Path, c.entries); err != nil {
			return nil, err
		}
		c.mtime = mtimeOf(cfg.Path)
	}

	return c, nil
}
