| Abstract | The Synthesizer-Generator (or simply Syn-Gen) is a software tool for building context sensitive editors. It has been applied to a wide variety of applications, ranging from programing language editors to editors that insure balanced chemical equations. The context sensitivity is provided by using attribute grammars. We provide an introduction to Syn-Gen and illustrate how it can be used to build programming language editors that only allow input of source code that compiles successfully. We then discuss use of Syn-Gen in two classes:- the study of attribute grammars in a graduate course on the formal specification of programming languages; in this course students completed a lab exercise dealing with the implementation of a context sensitive editor for a mini programming language.- the study of operational semantics in a junior level course; students used an editor implemented with Syn-Gen to study programming language translation and also completed an assignment to implement a very small piece of this editor dealing with the resolution of label numbers at the assembly language level.We found that assignments involving the details of Syn-Gen implementation were challenging due to the syntactic complexity of the Syn-Gen system. For such assignments to be successful, it was necessary to keep a tight rein on this complexity. Using Syn-Gen as a context sensitive editor without worrying about implementation was quite successful. In the future, we plan to explore the use of Syn-Gen to develop editors for mini-languages to help teach introductory students about the various programming paradigms: imperative, functional and logical. |

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.
