IncH: An Incremental Compiler for a Functional Language

IncH (Incremental Hope) is an incremental compiler for the functional language Hope, that is currently under development. The compiler is part of an interactive development environment, which makes small changes to the target code as the user uses a GUI editor to make changes to the source code. To do this, the IncH system maintains multiple intermediate representations of the source program, with inter­representational links maintaining correspondence information. This paper discusses the structure of the IncH compiler, as well as discussing aspects unique to the compilation of functional languages.
