syntax-trees

Convert between different Haskell syntax trees.

Latest on Hackage:0.1.2

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

Provides an instance that translates haskell-src-exts expression trees into Template Haskell expression trees in a way that depends only on the haskell-src-exts syntax tree and agreement on the pretty-printed representation of Haskell between haskell-src-exts pretty-printer and Template Haskell quotations (as opposed to depending on both TH and haskell-src-exts syntax tree representations).

Instead of converting between data types, haskell-src-exts syntax trees are pretty-printed and wrapped in a TH quotation which is then interpreted as a Haskell program, yielding a TH Exp tree. Free variables in the haskell-src-exts tree are preserved by lifting them to TH splices prior to pretty-printing.
