About this paper

Coeditor helps developers edit existing code by conditioning suggestions on recent repository changes and relevant code context. It represents edits as line-based additions and deletions, and uses static analysis to assemble related code context. On PYCOMMITS-ONELINE, its 220-million-parameter model achieves 60.4% enhanced exact match, versus 39.5% for text-davinci-003. This result concerns predicting one changed line, not repository-wide editing.
