Stars: 529
Hof is a CLI tool that unifies data models, schemas, code generation, and a task engine. It allows users to augment data, config, and schemas with CUE to improve consistency, generate multiple Yaml and JSON files, explore data or config with a TUI, and run workflows with automatic task dependency inference. The tool uses CUE to power the DX and implementation, providing a language for specifying schemas, configuration, and writing declarative code. Hof offers core features like code generation, data model management, task engine, CUE cmds, creators, modules, TUI, and chat for better, scalable results.
README:
A tool that unifies data models, schemas, code generation, and a task engine.
hof is a CLI tool you add to your workflow.
- Augment data, config, and schemas with CUE to improve consistency, gain confidence, and unlock new possibilities
- Generate multiple Yaml and JSON files in one-shot, from a CUE based source of truth
- Generate much of the application code, work directly in the output, regenerate without loss
- Explore data or config with the TUI, work with it using CUE in live-reload mode
- Run workflows with automatic task dependency inference, the right tasks are run in the right order
| Core Features | |
|---|---|
| code generation | Data + templates = _ (anything), technology agnostic |
| data modeling | Define, checkpoint, and diff data models |
| task engine | Extensible task and DAG workflow engine |
| CUE cmds | Core def, eval, export, and vet commands |
| creators | bootstraping and starter kits from any repo |
| modules | CUE module dependency management |
| tui | A terminal interface to Hof and CUE |
| chat | Combine LLM and Hof code gen for better, scalable results |
hof uses CUE to power the DX and implementation.
We believe CUE is a great language for specifying schemas, configuration, and generally
for writing anything declarative or this is a source of truth.
It has good theory and comes from the same people that brought us containers, Go, and Kubernetes.
