Evan Ovadia announces Valen, a fork of his Vale language aimed at seamless Rust interop with features like linear types, group borrowing, and cross‑language generics. He outlines current capabilities, open challenges, and a lazy AST‑signature approach to bridge the Rust ABI gap.
This post details a year of significant updates to w64devkit, a Windows development kit, including enhanced release security with code signing and immutability, and a multilib x64 toolchain. It also introduces new build tools like CMake, Ninja, and Ccache, alongside a custom C11 threads implementation and improvements to Binutils and GCC.
The author details building MoonForth, a Forth interpreter written in C that leverages Lua's C API for stack manipulation and word storage. The process was surprisingly straightforward, reinforcing the idea that Forth "writes itself" by iteratively filling missing functionality.
Unified (jumbo) builds concatenate multiple C++ source files to reduce header instantiation, often halving cold compile time. However, they hurt incremental rebuilds, cache efficiency, and can change program semantics, making reproducibility and correctness harder.
This issue of This Week in Rust summarizes recent developments in the Rust ecosystem, including official updates, community projects like OxiSH, observations on language features, and core Rust project changes. It covers compiler, library, Cargo, Rustdoc, and Clippy updates, offering a broad overview of the language's progress.
