What it is and what it does
Glean Parser is a command-line tool and library for working with Mozilla's Glean telemetry framework. It reads telemetry configuration files in YAML format (metrics.yaml and pings.yaml) and translates them into generated code for various Glean SDK integrations—such as Kotlin—while also performing validation and linting against the Glean schema. The tool is built on common Python libraries (Jinja2 for templating, jsonschema for validation, PyYAML for config parsing) and exposes both CLI commands and a programmatic API.
It is typically used by teams instrumenting applications with Glean telemetry to validate their metric definitions before deployment and to generate the boilerplate code needed to integrate those metrics into their SDKs. The package is actively maintained and supports modern Python versions (3.9 through 3.13).
Use it for
- Validate metrics.yaml and pings.yaml files against Glean schema before committing to a repository.
- Generate Kotlin code from telemetry configuration for Android applications using Glean.
- Lint telemetry definitions to catch configuration errors early in the development cycle.
- Integrate telemetry validation into CI/CD pipelines for Glean-instrumented projects.
- Check incoming Glean ping payloads against the ping schema for correctness.
