A code generator for F# that enables meta-programming by generating idiomatic F# code from AST input via plugins.
Myriad is a code generator for F# that enables meta-programming by generating idiomatic F# code from abstract syntax tree (AST) input. It solves the limitation of traditional F# type providers by producing native F# types like discriminated unions and records, allowing for more natural integration into F# projects. The tool operates via plugins that transform AST fragments into source code during the build process.
F# developers and teams looking to automate code generation, reduce boilerplate, and extend the F# compiler's capabilities without waiting for language-level features. It is particularly useful for those building libraries, frameworks, or applications that require repetitive code patterns.
Developers choose Myriad because it provides a flexible, plugin-based approach to meta-programming that integrates seamlessly with the F# ecosystem. Unlike type providers, it generates actual F# source code, enabling better tooling support, compiler optimizations, and idiomatic F# constructs.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Generates native F# types like records and discriminated unions, enabling compiler optimizations and better tooling support, unlike traditional type providers, as emphasized in the README's philosophy.
Supports custom plugins via NuGet packages or local DLLs, allowing extensible code generation tailored to specific needs, demonstrated in the external plugin integration section.
Integrates directly with MSBuild and CLI tools, with automatic dependency management via NuGet, reducing setup overhead, as shown in the MSBuild usage examples.
Enables extending F# compiler capabilities through plugins without altering the compiler itself, providing a safe and maintainable approach, as described in the project's goals.
Creating custom plugins requires deep knowledge of F# abstract syntax trees (AST) and the Myriad API, which can be a barrier for developers not versed in meta-programming, as hinted by the sparse plugin authoring documentation.
Only includes basic plugins like fields and lenses by default, forcing reliance on external plugins or custom development for advanced use cases, as noted in the external plugins list.
Requires meticulous MSBuild configurations, TOML files for plugin settings, and manual registration for external plugins, adding complexity to project setup, as seen in the plugin usage instructions.
