Described is a mechanism that provides the ability to save a snippet of visual programming logic within an automation building tool to be reused amongst different programs. The programming logic may be represented as a directed acyclic graph (DAG) such that the nodes of the graph correspond to various operations and the edges of the graph correspond to the logic flow of the program. The mechanism may provide a new capability to save a snippet of the visual programming logic while adhering to the requirements of a DAG structure. For example, a user may copy a valid substructure of visual programming logic in response to a validation that the programming logic may be inserted into another program. Accordingly, the mechanism provides an efficient and user-friendly mechanism to save portions of visual programming logic for reuse within an automation building tool.
