Interface Loader

loader.go:44–52

Loader is a minimal interface required for loading templates. Jet will build an absolute path (with slash delimiters) before looking up templates by resolving paths in extends/import/include statements: - `{{ extends "/bar.jet" }}` will make Jet look up `/bar.jet` in the Loader unchanged, no matte

// `/bar.html.jet` and `/bar.jet.html` (in that order). To avoid unneccessary lookups, use the full file name in your templates (so the first lookup
// is always a hit, or override this list of extensions using Set.SetExtensions().
type Loader interface {
	// Exists returns whether or not a template exists under the requested path.
	Exists(templatePath string) bool

	// Open returns the template's contents or an error if something went wrong.
	// Calls to Open() will always be preceded by a call to Exists() with the same `templatePath`.
	// It is the caller's duty to close the template.
	Open(templatePath string) (io.ReadCloser, error)
}

// OSFileSystemLoader implements Loader interface using OS file system (os.File).
