unified

Content as structured data

We compile content to syntax trees and syntax trees to content.
We also provide hundreds of packages to work on the trees in between.
You can build on the unified collective to make all kinds of interesting things.

Learn

We provide the interface: for parsing, inspecting, transforming, and serializing content. You work on structured data. Learn how to plug building blocks together, write your own, and make things with unified.

  1. mdx-js/eslint-mdx@eslint-plugin-mdx@3.9.1·

    Patch Changes

    • #629 8241610 Thanks @paoValle! - fix: mute the code block rules under their @stylistic names too

      eol-last and padded-blocks were deprecated in ESLint v8.53.0 in favour of @stylistic/eslint-plugin, which carries them with its own prefix. The code blocks config switches both off, and now also switches off @stylistic/eol-last and @stylistic/padded-blocks, so the examples stay muted for users who run the plugin.

      The deprecated entries stay: a rule set to off that the installed ESLint no longer has is bypassed rather than resolved, so they are inert on the version that removes them and still mute the rule on the versions that have it.

      Closes #601.

    Patch Changes

    • #634 7921c79 Thanks @JounQin! - fix: only apply remark fixes to the reported message range

      A remark fix used to rewrite the whole document, so unrelated formatting changes could conflict with prettier/prettier and produce circular fixes. Apply only the differences that overlap the reported message, as localized fixes.

      Closes #491.
