From 5ef7927dfad2374d4b26ae8cd10f6d00316c1d66 Mon Sep 17 00:00:00 2001 From: Rodolfo Hansen Date: Thu, 3 Sep 2026 17:15:50 +0200 Subject: [PATCH 1/6] Add linting: pre-commit + CI for markdown, spelling, and sample code - .pre-commit-config.yaml: hygiene checks, codespell, markdownlint-cli2 (pinned; local node hook), and a 72-char pane-width check for the refactoring samples (pages/refactorings/*.scala|.hs). - .markdownlint-cli2.yaml: shared markdown style (80-col prose, tables and headings exempt, compact pipe style allowed). - scripts/check-sample-width.sh: enforces the sample width rule the refactoring skill already documents (LESSONS.md 'pane width'). - .github/workflows/lint.yml: runs the same pre-commit config on every PR and push to master, so local and CI can't drift. - Fixes the pre-existing issues the new rules surface: a duplicated H1 and trailing-punctuation headings in the Refactorings post, trailing whitespace, long prose lines in about/libraries/README, a folded header_subtitle scalar, and a 'Vist' typo (Visit). --- .github/workflows/lint.yml | 27 +++++++++++++++++++ .markdownlint-cli2.yaml | 19 +++++++++++++ .pre-commit-config.yaml | 51 +++++++++++++++++++++++++++++++++++ CNAME | 2 +- Gemfile | 2 +- README.md | 24 ++++++++++++++--- _config.yml | 4 ++- pages/about.md | 9 ++++--- pages/libraries.md | 5 ++-- scripts/check-sample-width.sh | 19 +++++++++++++ type-on-strap.gemspec | 2 +- 11 files changed, 151 insertions(+), 13 deletions(-) create mode 100644 .github/workflows/lint.yml create mode 100644 .markdownlint-cli2.yaml create mode 100644 .pre-commit-config.yaml create mode 100755 scripts/check-sample-width.sh diff --git a/.github/workflows/lint.yml b/.github/workflows/lint.yml new file mode 100644 index 0000000..a5c650e --- /dev/null +++ b/.github/workflows/lint.yml @@ -0,0 +1,27 @@ +name: Lint + +on: + pull_request: + branches: [master] + push: + branches: [master] + +permissions: + contents: read + +jobs: + lint: + runs-on: ubuntu-latest + steps: + - uses: actions/checkout@v4 + + - uses: actions/setup-python@v5 + with: + python-version: "3.12" + + - uses: actions/setup-node@v4 + with: + node-version: "20" + + - name: Run pre-commit on all files + uses: pre-commit/action@v3.0.1 diff --git a/.markdownlint-cli2.yaml b/.markdownlint-cli2.yaml new file mode 100644 index 0000000..65fd0fb --- /dev/null +++ b/.markdownlint-cli2.yaml @@ -0,0 +1,19 @@ +# Markdown style for the site (markdownlint-cli2, shared with pre-commit, +# editors and CI).
