def get_source(env : Crinja, template : String) : ::Tuple(String, String) #
Description copied from class Crinja::Loader

Get the template source, filename and reload helper for a template. It's passed the environment and template name and has to return a tuple in the form {source : String, filename : String?} or raise a TemplateNotFoundError if it can't locate the template. The source part of the returned tuple must be the source of the template as string. The filename should be the name of the file on the filesystem if it was loaded from there, otherwise nil. The filename is used for the tracebacks if no loader extension is used.

def list_templates #
