cog

cog

cog is a CLI tool to generate code from schemas.

Maturity

The code in this repository should be considered experimental. Documentation is only available alongside the code. It comes with no support, but we are keen to receive feedback on the product and suggestions on how to improve it, though we cannot commit to resolution of any particular issue. No SLAs are available. It is not meant to be used in production environments, and the risks are unknown/high.

Grafana Labs defines experimental features as follows:

Projects and features in the Experimental stage are supported only by the Engineering teams; on-call support is not available. Documentation is either limited or not provided outside of code comments. No SLA is provided.

Experimental projects or features are primarily intended for open source engineers who want to participate in ensuring systems stability, and to gain consensus and approval for open source governance projects.

Projects and features in the Experimental phase are not meant to be used in production environments, and the risks are unknown/high.

Goals

• Support common schema formats: JSON Schema, OpenAPI, ...
• Generate code in a wide range of languages: Golang, Typescript, Java, ...
• Generate types described by schemas
• Generate developer-friendly builder libraries, allowing the creation of complex Grafana-related objects as-code

Usage

For the kind-registry:

$ git clone https://github.com/grafana/kind-registry ../kind-registry
$ devbox run gen-sdk-dev

Development setup

cog relies on devbox to manage all the tools and programming languages it targets.

A shell including all the required tools is accessible via:

$ devbox shell

This shell can be exited like any other shell, with exit or CTRL+D.

One-off commands can be executed within the devbox shell as well:

$ devbox run go version

Packages can be installed using:

devbox add go@1.23

Available packages can be found on the NixOS package repository.
