The old setup ran a Python spell checker that took more than three minutes on a Ruby Jekyll blog, and it was replaced with a RuboCop plugin. The plugins include rubocop-spellcheck, dylint-spellcheck for Rust, markdownlint-rule-spellcheck, and prettier-plugin-spellcheck, which uses Prettier's syntax trees to separate prose from code. Installing prettier-plugin-spellcheck 0.1.0 adds spell checking to an existing Prettier setup, as shown with no configuration. Copilot initially built the Prettier plugin as a wrapper around the markdownlint plugin, which the author flags as a caution. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I add spell checking to my existing Prettier setup without a new tool? Install prettier-plugin-spellcheck as a dev dependency alongside prettier (e.g. version 0.1.0), then run prettier with the --plugin flag. It reuses Prettier's existing syntax trees for Markdown, HTML, and JavaScript/TypeScript to distinguish prose from code, flagging misspelled words with suggestions, so no separate linter or config file is needed. _Developers consolidating lint tooling track plugin releases like this one on daily.dev._ ### Is there a RuboCop plugin for spell checking Ruby code and comments? Yes, rubocop-spellcheck adds spelling checks to RuboCop, covering Ruby comments, strings, identifiers, Markdown, RDoc, AsciiDoc, and plain text. It was built to replace a slower standalone Python spell checker that took over three minutes to run on a Ruby Jekyll blog, integrating spelling into the same cop configuration, exclusions, and CI setup as other RuboCop checks. _Ruby maintainers weighing which linters to adopt follow tool releases like this via daily.dev._ ## Similar posts on daily.dev - [Introducing RuboCop Spellcheck](https://daily.dev/posts/introducing-rubocop-spellcheck-wpmhmat9m) · RUBYLAND · 0 upvotes · 0 comments - [Introducing Markdownlint Spellcheck](https://daily.dev/posts/introducing-markdownlint-spellcheck-auc79abor) · RUBYLAND · 0 upvotes · 0 comments - [Writing custom RuboCop rules in 2026—Martian Chronicles, Evil Martians’ team blog](https://daily.dev/posts/writing-custom-rubocop-rules-in-2026-martian-chronicles-evil-martians-team-blog-ucy58o2jj) · Martian Chronicles · 0 upvotes · 0 comments - [Introducing Dylint Spellcheck \(Rust\)](https://daily.dev/posts/introducing-dylint-spellcheck-rust--cst5opstc) · RUBYLAND · 0 upvotes · 0 comments - [RuboCop 1.92: Agents Welcome](https://daily.dev/posts/rubocop-1-92-agents-welcome-hlocmovru) · Meta Redux · 0 upvotes · 0 comments --- Tags: [#vibe-coding](https://daily.dev/tags/vibe-coding) [View this post on daily.dev](https://daily.dev/posts/one-tool-for-the-spell-checking-job-mwlbosmzd) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"One Tool for the (Spell Checking) Job","url":"https://daily.dev/posts/one-tool-for-the-spell-checking-job-mwlbosmzd","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/one-tool-for-the-spell-checking-job-mwlbosmzd"},"datePublished":"2026-10-29T14:23:08.764Z","dateModified":"2026-10-29T14:23:40.397Z","description":"A developer built four spell-checking plugins in a week instead of adding new language runtimes and tools.
