    I’m a little out of date with Java, but I believe Checkstyle is currently popular:

    Project mention: Incident with GitHub Actions, Issues, Pull Requests, and Webhooks | | 2021-10-21

    I used ReviewDog to wire in Qodana results, so I hear you about wishing it was built in, but it is achievable:

    Based on my contact with GitLab's built-in other scanning tools, I wouldn't trust their vuln management further than I could throw it, so you're likely not missing much on that front

  • GitHub repo SimpleCov

    Code coverage for Ruby with a powerful configuration library and automatic merging of coverage across test suites

    Project mention: How to test all workers in one big loop? | | 2021-12-02

    simplecov might the answer you need, it generates a report of the lines of code your test suite hits.

  • GitHub repo FBRetainCycleDetector

    iOS library to help detecting retain cycles in runtime.

  • GitHub repo Pylint

    It's not just a linter that annoys you!

    Project mention: When is it bad to use OOP? | | 2021-09-30

    So it doesn't say it isn't justified, it indicates that you might want to reconsider. So by leaving out that nuance, you're promoting this to a binary bad/wrong label which it really isn't. Also consider it's a bit obsolete in context of for example dataclasses and custom exceptions, as those often have 0 methods unless you need something extra from them. See for example complaint tickets about these and So to summarize, using a linter's best effort to indicate something that can easily be a non-issue isn't exactly the best source for programming style rules.

  • GitHub repo GrumPHP

    A PHP code-quality tool

    Project mention: Tools you’ve used to increase code quality and/or productivity? | | 2021-12-02

    Project mention: Is it possible to measure spaghettiness of code? | | 2021-11-25

    This is the definition of cohesion and there are many great tools to calculate cohesion metrics (depending on the programming language e.g Java). Cohesion metrics belong to a bigger set of metrics called OOP metrics (or ck metrics). Check out the following links:

  • GitHub repo OCLint

    A static source code analysis tool to improve quality and reduce defects for C, C++ and Objective-C

    Project mention: C/C++ pre-commit hooks for static analyzers and linters | | 2021-09-13

    Project mention: CoreData common practice - Do you usually have a struct based data class, as the bridge between your UI layer, and the CoreData data layer? | | 2021-06-13

    CleanArchitectureRxSwift has a concrete demonstration of how using separate structs can help you use isolate persistence so as to use the same view controller with either Realm or CoreData (that obviously applies to more recent persistence options as well).
