It is commonly added as a Mix development/test dependency and run with mix credo to report refactoring opportunities, complex code, common mistakes, naming inconsistencies, and style issues. ### Project history The official changelog identifies version 0.1.0 as the initial release. Early releases added CLI behavior, issue categories, per-function lint support, custom checks, generated configuration, and support for project-specific .credo.exs files. ### Adoption history Credo became part of normal Elixir project hygiene because it fits the Mix workflow and publishes documentation on HexDocs. The README also documents editor and automated-code-review integrations, which helped make it useful both locally and in CI. ### How it is used The README recommends adding {:credo, "~> 1.7", only: [:dev, :test], runtime: false} to mix.exs, running mix deps.get, and then running mix credo. Configuration is usually generated or maintained in .credo.exs. ### Why package nerds care For package maintainers, Credo is the Elixir ecosystem's familiar lint-style dependency: it ships through Hex, exposes a Mix task, can fail CI through exit status, and has enough formatter and integration surface to appear in editor, CI, and code-review pipelines. ### Timeline - 0.1.0: Initial release - 0.2.0: Added non-zero exit status when issues are found - 0.3.0: Added per-function lint support - 0.4.0: Added custom check support and changed .credo.exs merging behavior - 1.0.0: Stabilized the 1.x line with documentation and breaking changes for custom checks - 1.7.0: Added SARIF output and check IDs ### Related projects - The README lists editor integrations for JetBrains Elixir support, Atom, VS Code, flycheck, Kakoune, and Neovim/null-ls, plus Codacy for automated code review. ### Sources - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
