@shopify/theme-check-common@3.28.0

Minor Changes

• 6803e99: Adopt the hand-written liquid-html-parser for performance

  Replace the parser-combinator-based Liquid/HTML parser with a hand-written
  recursive-descent parser. The new parser is significantly faster, adds
  resilient parsing (it recovers from malformed input instead of bailing), and is
  adapted to the theme-tools source model. theme-language-server-common,
  theme-check-common, prettier-plugin-liquid, and theme-graph are updated to
  consume the new parser.

• 6803e99: Port additional theme-check checks

  Add the following checks:

  • LiquidComplexity -- Reports Liquid files with high cyclomatic complexity (default threshold 120).
  • LiquidNestingDepth -- Reports Liquid files with deeply nested control-flow structures (default max depth 10).
  • LiquidSyntaxError -- Reports Liquid syntax errors.
  • MaxFileSize -- Reports theme files that exceed Shopify's maximum per-file size.
  • ExcessiveSettingsCount -- Reports section/block schemas declaring more top-level settings than the max (default 40).
  • BlockArgumentSettingCollision -- Reports a plain block-tag argument whose name matches a setting id in the block's schema.
  • DuplicateBlockArguments -- Reports duplicate argument names in a block tag.
  • MissingBlockArguments -- Reports required {% doc %} arguments not provided on a block tag.
  • UnknownBlockSetting -- Reports a block.settings.<name> argument where <name> is not in the block's schema.
  • UnrecognizedBlockArguments -- Reports block-tag arguments not declared in the block's {% doc %} tag.
  • ValidBlockArgumentTypes -- Reports type mismatches between block-tag arguments and their {% doc %} declarations.
  • SchemaOncePerFile -- Reports when {% schema %} appears more than once in a file.
  • SchemaSectionOrBlockOnly -- Reports {% schema %} used outside section or block files.
  • StylesheetOncePerFile -- Reports when {% stylesheet %} appears more than once in a file.
  • StylesheetTagInWrongFile -- Reports {% stylesheet %} used outside section, block, or snippet files.
  • JavascriptOncePerFile -- Reports when {% javascript %} appears more than once in a file.
  • JavascriptTagInWrongFile -- Reports {% javascript %} used outside section, block, or snippet files.

  RequiredLayoutThemeObject now flags any layout/*.liquid file missing the required theme objects, not just layout/theme.liquid.
