| Abstract | Bug fixes and feature additions to large code bases often require systematic edits-similar, but not identical, coordinated changes to multiple places. This process is tedious and error-prone. Our prior work introduces a systematic editing approach that creates generalized edit scripts from exemplar edits and applies them to user-selected targets. This paper describes how the Sydit plug-in integrates our technology into the Eclipse integrated development environment. A programmer provides an example edit to Sydit that consists of an old and new version of a changed method. Based on this one example, Sydit generates a context-aware, abstract edit script. To make transformations applicable to similar but not identical methods, Sydit encodes control, data, and containment dependences and abstracts position, type, method, and variable names. Then the programmer selects target methods and Sydit customizes the edit script to each target and displays the results for the programmer to review and approve. Sydit thus automates much of the systematic editing process. To fully automate systematic editing, future tool enhancements should include automated selection of targets and testing of Sydit generated edits. |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
