A community-driven style guide for Elixir, implemented as checks in the Credo static analysis tool.
The Elixir Style Guide is a community-driven set of conventions and best practices for writing Elixir code. It defines standards for formatting, naming, documentation, and code structure to improve consistency and readability across projects. The guide is implemented as checks in Credo, a static analysis tool that helps developers adhere to these conventions automatically.
Elixir developers and teams who want to maintain consistent, readable, and maintainable codebases, especially those using or contributing to the Credo linter.
It provides a pragmatic, non-dogmatic set of guidelines backed by the Credo tool, making it easy to enforce consistency. Unlike rigid style guides, it focuses on practical readability and community collaboration, helping teams write code that is easier to understand and contribute to.
Style Guide for the Elixir language, implemented by Credo
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Focuses on consistency and readability over strict dogma, as stated in the Philosophy section, making it adaptable for various project needs.
Directly underpins the Credo static analysis tool, enabling automated enforcement of style rules in CI/CD pipelines, as mentioned in the GitHub description.
Covers code formatting, naming, documentation, refactoring, and pitfalls with clear examples, such as preferring 80-character lines and proper use of sigils, detailed in multiple sections.
Draws from Ruby style guides and other Elixir attempts, and is open to contributions via pull requests, ensuring it evolves with community input, as noted in the Contribute section.
The guide is purely documentation; enforcing rules requires integrating with Credo or manual code reviews, which adds overhead and setup complexity.
Some rules, like 'keep lines fewer than 80 characters whenever possible,' are subjective and can lead to inconsistent interpretation across teams, as admitted in the README.
Does not address cross-language consistency or provide tools for projects using multiple programming languages, limiting its utility in polyglot environments.
