What this system is

This system is a maintenance-focused F\# compiler host and dependency management tool, specifically centered around the Queil.FSharp.FscHost and Paket integration. Recent activity has prioritized stabilizing the host environment and resolving dependency issues, alongside significant efforts to improve test coverage. The codebase appears to be in a phase of routine upkeep and reliability hardening rather than feature expansion.

How it got here

2021 — Dependency maintenance

2 changes.

This period focused on routine dependency management within the Queil.FSharp.FscHost project. The work involved removing the MinVer automatic versioning tool and upgrading the FSharp.Core library to its stable 6.0.0 release. These changes streamlined the build process and ensured compatibility with the latest stable F\# core components.

May 2026 — 43 commits adding/updating tests in tests

1 change.

Test coverage in tests — 43 commits (21 fixs), 9 files.

June 2026 — F\# host and dependency manager fixes

2 changes.

This period focused on stabilizing the F\# compiler host and the Paket dependency manager. The majority of activity involved fixing issues within the Queil.FSharp.FscHost component, which saw significant changes across multiple files. Additionally, targeted fixes were applied to the Queil.FSharp.DependencyManager.Paket module to resolve dependency-related problems.

queil/fsc-host was measured the same way every project in this corpus was: the same rubric, at a pinned commit, with the result published in full. Point a surveyor at a repository you know and see whether you agree with it.

About this page

  • The score is its most recent published measurement, taken on 3 October 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit ed7fa6bed46f45e893cda87f329aca27ad4c41f9 — the exact code this score is about.
  • Scored under rubric-2026.10.1 — the same rubric and the same method as every other entry in this index.
  • Measured by watchdog.canine.dev using codehealth-analyzer preprod-4f4226d619ea.
