axe-playwright vs elan

axe-playwright adds axe-core accessibility checks to Playwright tests. Its commands can inject and configure axe, check a page, retrieve results or violations, and report findings. Checks can cover a whole page document or a selected DOM context such as a selector. Options support axe.run settings, impact filtering, detailed reports, and verbose output; an optional setting logs violations without failing the test. The integration works with Playwright’s Chromium, Firefox, and WebKit browsers. Reporting options include terminal output, a v2 terminal format, HTML, and JUnit. The project shows configurations for WCAG 2.1 AA, WCAG 2.2 AA, best-practice, and EN 301 549 tags, and lists WCAG 2.2 coverage. Installation uses axe-playwright and Playwright as npm development dependencies. axe-core is bundled, so a separate installation is not needed. The package is distributed under the MIT License. It is available for Linux and web, with CI/CD integration. The project says it is not formally affiliated with Deque Systems, though it uses axe-core with permission.

elan manages installations of the Lean theorem prover on Linux, macOS and Windows. Its `lean` and `lake` binaries use a project’s `lean-toolchain` file to select the specified Lean version and download it when needed. The separate `elan` command provides manual control to install, select, run or uninstall Lean versions. The project supports version pinning, lockfiles, automatic switching, shell integration and CI/CD use. Installation options include shell instructions for Linux and macOS, a PowerShell method for Windows, and release downloads for supported platforms. The README recommends the Nixpkgs version on NixOS because toolchains downloaded by elan require patching there. Lake needs git to download dependencies. The project describes itself as a fork of rustup adapted for Lean infrastructure. elan is free at free, and the repository lists Apache-2.0 and MIT licenses. The releases page identifies v4.2.4 as the latest release.
