Haskell WebAssembly Toolkit

Goals

• Provide a WebAssembly code generation tool for Haskell
• Create an infrastructure for Cmm to WebAssembly code generator
• Have Fun :)

Status

• Lexer: supports nested block comments and all lexemes from the WebAssembly Spec
• Parser: parses all examples from WebAssembly Core TestsSuit (including folded instructions parsing)
• Renaming Phase: substitute identifiers with correct indexes, expand all implicit type declarations)
• Binary format parser/serializer
• Validation Phase: execute a verification procedure from the Spec
• Execution Phase: implement a simple interpreter
• Support extended Core Test Suit assertion grammar

Todo

• Improve error messages for text representation parsing
• Text Representation pretty-printer
• Compile Core Tests to Tasty test cases and pass all tests
• Command line tool for calling interpreter/compiler/validator
• Codegen interface for type enforced generating valid WASM code
