Description

- Domain and Purpose

  GHC.JS.Syntax defines the Syntax for the JS backend in GHC. It comports with the ECMA-262 although not every production rule of the standard is represented. Code in this module is a fork of JMacro (BSD 3 Clause) by Gershom Bazerman, heavily modified to accomodate GHC's constraints.

- Strategy

  Nothing fancy in this module, this is a classic deeply embedded AST for JS. We define numerous ADTs and pattern synonyms to make pattern matching and constructing ASTs easier.

- Consumers

  The entire JS backend consumes this module, e.g., the modules in GHC.StgToJS.*. Please see `Make` for a module which provides helper functions that use the deeply embedded DSL defined in this module to provide some of the benefits of a shallow embedding.
