Pylint
It's not just a linter that annoys you!
Pylint is a static code analyzer for Python 2 or 3. The latest version supports Python 3.7.2 and above. Pylint analyses your code without actually running it. It checks for errors, enforces a coding standard, looks for code smells, and can make suggestions about how the code could be refactored. Projects that you might want to use alongside pylint include flake8 (faster and simpler checks with very few false positives), mypy, pyright or pyre (typing checks), bandit (security-oriented checks), black and isort (auto-formatting), autoflake (automated removal of unused import or variable), pyupgrade (automated upgrade to newer python syntax) and pydocstringformatter (automated pep257). Pylint isn't smarter than you: it may warn you about things that you have conscientiously done or checks for some things that you don't care about. During adoption, especially in a legacy project where pylint was never enforced. -

Elixir Code Smells
Catalog of Elixir-specific code smells
Elixir-Code-Smells is a research-driven catalog of code smells specific to the Elixir programming language. Unlike generic code smell lists, this project identifies issues emerging from Elixir’s functional, concurrent, and process-based nature. Initially compiled via grey literature (blogs, talks, forums), the catalog now includes 23 Elixir-specific smells plus 12 traditional smells adapted to Elixir. Each entry documents the name, category, problem, example, refactoring strategy, and step-by-step treatments. The smells are grouped into two categories: design-related (coarse-grained, harder to detect, affecting architecture/processes) and low-level concerns (fine-grained, often readability and maintainability issues). The catalog evolves with community feedback and contributions, aiming to help developers recognize harmful patterns and apply disciplined refactoring to improve maintainability, testability, and performance in Elixir systems. -

Twitter's Jetpack Compose Rules
Static checks to aid with a healthy adoption of Compose
Twitter Compose Rules is a set of custom ktlint rules to ensure that your compostables don't fall into common pitfalls, that might be easy to miss in code reviews. It can be challenging for big teams to start adopting Compose, particularly because not everyone will start at the same time or with the same patterns. Twitter tried to ease the pain by creating a set of Compose static checks. Compose has lots of superpowers but also has a bunch of foot guns to be aware of as seen in this Twitter Thread. This is where our static checks come in. We want to detect as many potential issues as we can, as quickly as we can. In this case, we want an error to show prior to engineers having to review the code. Similar to other static check libraries we hope this leads to a "don't shoot the messengers" philosophy which will foster healthy Compose adoption. -

i18n-tasks
Manage translation and localization with static analysis, for Ruby i18
Manage translation and localization with static analysis, for Ruby i18n. i18n-tasks helps you find and manage missing and unused translations. This gem analyses code statically for key usages, such as I18n.t('some.key'), in order to report keys that are missing or unused. Pre-fill missing keys, optionally from Google Translate or DeepL Pro. Remove unused keys. Thus addressing the two main problems of i18n gem design, missing keys only blow up at runtime. i18n-tasks can be used with any project using the ruby i18n gem (default in Rails). i18n-tasks health checks if any keys are missing or not used, that interpolations variables are consistent across locales, and that all the locale files are normalized (auto-formatted). -
