Webassembly is here
Quartex Pascal has completed a functional WebAssembly codegen, letting the compiler emit WAT and binary WASM alongside a JavaScript glue layer for calling WASM functions from QTX applications. The variant datatype, central to QTX's JS interop, will not be supported in WASM due to the performance overhead of runtime type tagging that WASM's lack of pointers would require. A new 'wasm' RTL namespace is planned to clone the system namespace for WASM-compatible code, though work on it hasn't started. Classes, records, and collections work inside WASM but can't cross the WASM-to-JavaScript boundary; interop still happens via external functions and procedures, similar to writing a DLL in Delphi. A command-line preview of the WASM compiler is planned for customers in the coming weeks, followed later by IDE integration.
