Working with source plugins
Matthew Caleb Pickering, Nicolas Wu, Boldizsár Németh · 2019
A modern compiler calculates and constructs a large amount of information about the programs it compiles. Tooling authors want to take advantage of this information in order to extend the compiler in interesting ways. Source plugins are a mechanism implemented in the Glasgow Haskell Compiler (GHC) which allow inspection and modification of programs as they pass through the compilation pipeline.
