| Abstract | Parser combinators are a popular approach to parsing. Parser combinators follow the structure of an underlying grammar, are modular, well-structured, easy to maintain, and can recognize a large variety of languages including context-sensitive ones. However, their universality and flexibility introduces a noticeable performance overhead. Time-wise, parser combinators cannot compete with parsers generated by well-performing parser generators or optimized handwritten code. Techniques exist to achieve a linear asymptotic performance of parser combinators, yet there is still a significant constant multiplier. This can be further lowered using meta-programming techniques. In this work we present a more traditional approach to optimization --- a compiler --- applied to the domain of parser combinators. A parser combinator compiler (pc-compiler) analyzes a parser combinator, applies parser combinatorspecific optimizations and, generates an equivalent high-performance top-down parser. Such a compiler preserves the advantages of parser combinators while complementing them with better performance. |

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.
