| Abstract | Dynamic languages play an increasingly prominent role in modern software development. They are used in domains as diverse as web programming and scientific computing, for developing simple scripts as well as large applications. Tool-supported refactoring for these languages can bring important benefits to programmers. First, manual refactoring tends to be error-prone in dynamic languages since they impose very little static structure; hence, erroneous refactorings often cannot be detected until runtime. A tool can use static program analysis to check the soundness of a proposed refactoring, thus mitigating this problem. Second, dynamic languages tend to lack constructs for modularisation and encapsulation, which can be an obstacle to writing maintainable software. In many cases, such constructs can be emulated using other language features, but refactoring a program to make use of such patterns is often non-trivial and could benefit from tool support. Third, refactoring tools can be useful for adapting programs to use high-level features, thus supporting script to program evolution. However, specifying and implementing refactorings for dynamic languages is a challenging endeavour. We highlight some of the major issues in this area, and discuss recent progress towards solving them. |

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.
