Compositionality is a fundamental notion in computation whereby complex abstractions can be constructed from simpler ones, but this property has so far escaped the paradigm of end-user programming from examples or natural language. Existing approaches restrict end users to only give holistic end-to-end specifications, which limits the expressivity and scalability of these approaches to relatively simple programs in very restricted domains. In this paper we propose a new approach to end-user program synthesis in which input can be given in a compositional manner through a combination of natural language and examples. We present a domain-agnostic program synthesis algorithm and demonstrate its application to an expressive string manipulation language. We evaluate on a range of complex examples from help forums that are beyond the scope of previous systems.
