Autocompletion of Code from Keywords


Jun 02, 2018 Blind Submission readers: everyone
  • Abstract: We present a simple approach for synthesizing code from keywords. Our system takes keywords, a subset of tokens from the target code, and generates a line of code. The main challenge is that we only have the output of the system and do not know the real input distribution. We construct simple synthetic distributions by dropping each keyword randomly and based on its frequency, which still generalize to various test distributions. We train a standard sequence-to-sequence model on the synthetic training data and successfully synthesize 71.5% of examples in our manually generated test set. Our approach is simple and language-agnostic and therefore can be easily extended and applied to any programming language.

  • TL;DR: Given "for i 10" as input, our system outputs the code "for i in range(10):".
