Indentation sensitive parsing combinators for Parsec


Michael D. Adams and Ömer S. Ağacan. Indentation-sensitive parsing for Parsec. In Proceedings of the 2014 ACM SIGPLAN Symposium on Haskell, Haskell ’14, pages 121–132. ACM, New York, NY, USA, September 2014. ISBN 978-1-4503-3041-1. doi:10.1145/2633357.2633369.

This package provides indentation combinators for Parsec. For Trifecta, install indentation-trifecta. For backward compatability or to install both, install indentation.


  • Bump base bounds to support GHC 8.2.1


  • Split indentation into separate indentation-core, indentation-parsec and indentation-trifecta packages. Keep the original indentation for backward compatability and as a general roll-up package.
