sqlc is a SQL compiler and code generator that creates type-safe database client code from raw SQL queries. It transforms SQL statements into typed definitions and functions, eliminating the need for manual row mapping between database results and application structures. The tool ensures compile-time safety by validating SQL queries against the database schema before the application is run. This workflow integrates the database schema directly into the application code, deriving types from the underlying SQL definitions to prevent runtime errors. The system utilizes AST-based query analysis

gotests is a static analysis tool and boilerplate generator for Go that automatically creates structured test suites from source code. It functions as a table-driven test framework that handles type resolution for functions and methods, including the mapping of generic type constraints to concrete implementation types. The tool integrates with large language models to synthesize realistic input values and edge cases based on function logic. It uses a template-driven generation system, allowing the structure and format of the resulting test code to be customized through external templates and

Tools to let you use Roslyn-powered C# scripts for code generation. You can think of it as a scripted alternative to T4 templates.

Assists in performing Roslyn-based code generation during a build. This includes design-time support, such that code generation can respond to changes made in hand-authored code files by generating new code that shows up to Intellisense as soon as the file is saved to disk.

Testura.Code is a wrapper around the Roslyn API and used for generation, saving and compiling C# code. It provides methods and helpers to generate classes, methods, statements and expressions.

The Uno source generator is an API compatible source generator inspired by Roslyn v2.0 source generation feature, and an msbuild task which executes the SourceGenerators.
