Most programmers make mistakes when writing code. Some of these mistakes are<\/div>\n
small and require few edits to the original program \u2013 a class of errors recently<\/div>\n
termed last mile mistakes. These errors break the flow for experienced<\/div>\n
developers and can stump novice programmers. Existing automated repair<\/div>\n
techniques targeting this class of errors are language-specific and do not<\/div>\n
easily carry over to new languages. Transferring symbolic approaches requires<\/div>\n
substantial engineering and neural approaches require data and retraining. We<\/div>\n
introduce RING, a multilingual repair engine powered by a large language model<\/div>\n
trained on code (LLMC) such as Codex. Such a multilingual engine enables a<\/div>\n
flipped model for programming assistance, one where the programmer writes code<\/div>\n
and the AI assistance suggests fixes, compared to traditional code suggestion<\/div>\n
technology. Taking inspiration from the way programmers manually fix bugs, we<\/div>\n
show that a prompt-based strategy that conceptualizes repair as localization,<\/div>\n
transformation, and candidate ranking, can successfully repair programs in<\/div>\n
multiple languages with minimal effort. We present the first results for such a<\/div>\n
multilingual repair engine by evaluating on 6 different languages and comparing<\/div>\n
performance to language-specific repair engines. We show that RING can<\/div>\n
outperform language specific repair engines for three of these languages.<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
