A study on repetitiveness of code completion operations

In current software development, code completion is necessary to enhance productivity of our programming tasks. However, how developers use code completion tools on integrated development environments is still not elucidated completely. Aiming to improve such tools, we performed an investigation in terms of code completion use. We investigated developers´ operation histories on an integrated development environment and found that code completion operations inserting the same text tend to be repetitively performed in a short time period. We also propose new code completion strategies to reduce such repetitive code completion.
