| Abstract | Refactoring has become an integral part of modern software development, with wide support in popular integrated development environments (IDEs). Modern IDEs provide a fixed set of supported refactorings, listed in a refactoring menu. But with IDEs supporting more and more refactorings, it is becoming increasingly difficult for programmers to discover and memorize all their names and meanings. Also, since the set of refactorings is hard-coded, if a programmer wants to achieve a slightly different code transformation, she has to either apply a (possibly non-obvious) sequence of several built-in refactorings, or just perform the transformation by hand. We propose a novel approach to refactoring, based on synthesis from examples, which addresses these limitations. With our system, the programmer need not worry how to invoke individual refactorings or the order in which to apply them. Instead, a transformation is achieved via three simple steps: the programmer first indicates the start of a code refactoring phase; then she performs some of the desired code changes manually; and finally, she asks the tool to complete the refactoring. Our system completes the refactoring by first extracting the difference between the starting program and the modified version, and then synthesizing a sequence of refactorings that achieves (at least) the desired changes. To enable scalable synthesis, we introduce local refactorings, which allow for first discovering a refactoring sequence on small program fragments and then extrapolating it to a full refactoring sequence. We implemented our approach as an Eclipse plug-in, with an architecture that is easily extendable with new refactorings. The experimental results are encouraging: with only minimal user input, the synthesizer was able to quickly discover complex refactoring sequences for several challenging realistic examples. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
