caffeine_lang

The pure compiler core for the Caffeine DSL. It generates reliability SLOs (Terraform for Datadog) from service expectation definitions. The vendor abstraction (Vendor enum, Platform registry, multi-vendor compiler dispatch) is in place so additional vendors can be added by registering a new Platform and generator module.

Usage

As a Gleam dependency

# gleam.toml
[dependencies]
caffeine_lang = ">= 5.2.0 and < 6.0.0"

import caffeine_lang/compiler

let result = compiler.compile_from_strings(blueprints, expectations, output_path)

In the browser

import { compile_from_strings } from "./caffeine-browser.js";
const result = compile_from_strings(blueprintsJson, expectationsJson, "org/team/service.json");

Looking for the CLI or LSP?

The installable binary (CLI + Language Server) lives in the caffeine repo:

brew tap brickell-research/caffeine
brew install caffeine_lang
