Three-way merge tools play crucial roles in modern software development, where a developer forks a branch to make local modifications and requests it to be merged into the main branch via a “pull request.” Despite its importance, the task has traditionally been defined in an intuitive manner, and the results of merge tools are often accepted without scrutiny. In this paper, we present a new structural merge tool in comparison with existing tools based on the syntactic criteria we propose for evaluating the merge results. We require the merge result to be both parsable and universal. Being parsable means that the result is syntactically valid according to the grammar of the programming language. Being universal means that the result incorporates all and the only edit operations occurring in each branch while ensuring that edits common to both branches are applied only once. This requirement can be precisely defined using the notion of pushouts in category theory. In a large-scale experiment involving 43,774 file merge scenarios from 76 open-source Java projects, we found a number of incorrect results reported by the existing tools such as the Git companion merge tool, whereas our tool reports none. We expect that the proposed criterion will help in developing reliable merge tools in the future.
