compiler/main/Plugins.hs¶
Note [Source plugins]¶
The Plugin datatype have been extended by fields that allow access to the different inner representations that are generated during the compilation process. These fields are parsedResultAction, renamedResultAction, typeCheckResultAction, spliceRunAction and interfaceLoadAction.
The main purpose of these plugins is to help tool developers. They allow development tools to extract the information about the source code of a big Haskell project during the normal build procedure. In this case the plugin acts as the tools access point to the compiler that can be controlled by compiler flags. This is important because the manipulation of compiler flags is supported by most build environment.
