Hackage Stackage Nightly Travis Build Status haskell-src-exts-util

A small suite of helper functions for working with haskell-src-exts:

  • Free variables
  • Bound variables
  • Minimal (approximate) rebracketing of AST values such that prettyprint roundtrips.

Acknowledgments

This package extracts some the HSE functions in HLint and generalizes them. The original code was authored over the years by Neil Mitchell and the rest of HLint contributors.

Changes

0.2.2

  • Improved handling of OverloadedLabel syntax, thanks to Neil M.
  • Changed the treatment of multiple function composition in needParen. The new treatment is less keen to remove parentheses. Note that this is a change of behavior.
  • GHC 8.4 compatibility, courtesy of Ryan G. Scott
