dburriss/fennel

Fennel is a .NET library designed for parsing and generating Prometheus metric strings. It provides a C\# API that transforms raw text into structured line objects and formats metrics for export. Recent development has focused on refining the parsing API and updating the underlying .NET runtime, indicating a stable, maintenance-oriented trajectory for this utility component.

• Bounded contexts: Fennel

12 changes.

This period established the Fennel library by setting up the project structure, dependencies, and initial unit tests for Prometheus text parsing. Development then progressed to implementing a C\# API for generating Prometheus metric strings, including refactoring the parser to handle unknown metric types and optional numeric values. The work concluded with comprehensive testing and the release of version 0.2.0.

3 changes.

The period focused on refactoring the ParseText method within the Fennel source to return a sequence of ILine objects instead of its previous format. This behavioral change was accompanied by the addition of specific test assertions to verify the new return type and content. The work also included a minor dependency update and migration of tests to .NET 5 as part of the 0.3.0 release preparation.
