CGP v0.7.0 has been released, bringing a major expansion to the CGP macro toolkit. The centerpiece of this release is a suite of new annotations — #[cgp_fn], #[implicit], #[uses], #[extend], #[use_provider], and #[use_type] — that let you write context-generic code in plain function syntax with dramatically less boilerplate than before.
If you have visited our website before, you might have noticed that the CGP project website has received a beautiful overhaul redesign with a fresh look and feel. This transformation comes from our migration away from Zola to Docusaurus, a move driven by our commitment to significantly expand and improve the documentation for CGP.
We're excited to announce the release of cgp v0.6.1, which brings several quality-of-life improvements to Context-Generic Programming in Rust. This release focuses on making CGP more accessible to developers new to the paradigm while also providing better debugging and verification tools for complex provider setups.
The changes in this release reflect our commitment to lowering the barrier to entry for CGP, while maintaining the power and flexibility that make it such a compelling approach to modular Rust code. Whether you're an experienced CGP user or just getting started, we believe you'll find these improvements meaningful.
I am excited to announce the release of cgp-serde, a modular serialization library for Serde that leverages the power of Context-Generic Programming (CGP).
In short, cgp-serde extends Serde’s original Serialize and Deserialize traits with CGP, making it possible to write overlapping or orphaned implementations of these traits and thus bypass the standard Rust coherence restrictions.
Furthermore, cgp-serde allows us to leverage the powerful context and capabilities concepts in stable Rust today. This unlocks the ability to write context-dependent implementations of Deserialize, such as one that uses an arena allocator to deserialize a 'a T value, a concept detailed in the proposal article.
It has only been two weeks since v0.5.0 was released, yet we are already introducing another major update. CGP v0.6.0 brings significant improvements to the ergonomics of implementing providers and contexts, making it easier and more intuitive for developers to build on top of CGP.
CGP v0.5.0 has been released, bringing a range of new features and some breaking changes as part of the ongoing effort toward stabilization. This version introduces several improvements to make CGP more practical, expressive, and easier to use in real-world Rust projects.
The highlights of this major release are summarized below. Also check out the changelog for the full list of changes.
I’m excited to announce the release of CGP v0.4.2, a major milestone that significantly expands the expressive power of generic programming in Rust. With this release, CGP introduces full support for extensible records and variants, unlocking a range of new capabilities for developers working with highly modular and reusable code.
Extensible records and variants allow developers to write code that operates on any struct containing specific fields or any enum containing specific variants, without needing their concrete definition. This makes it possible to write truly generic and flexible logic that is decoupled from rigid type definitions.
We are excited to announce the release of CGP v0.4.1! This release brings several new features, quality-of-life improvements for macro usages, and a new crate cgp-handler.
Here are some of the highlights:
cgp-handler crate: Provides abstract interfaces for defining components with common method signatures.cgp_preset! macro improvement: Now supports wrapping of Preset::Provider.#[cgp_component] macro improvement: Now supports automated derivation of UseDelegate.I am thrilled to introduce Hypershell, a modular, type-level domain-specific language (DSL) for writing shell-script-like programs in Rust. Hypershell is powered by context-generic programming (CGP), which makes it possible for users to extend or modify both the language syntax and semantics.
It's been a while since the last update, but the wait is over! I'm thrilled to announce the release of v0.4.0 of the cgp crate. This version is packed with tons of new features and delivers a dramatically smoother developer experience!
