v0.18.17

• Support An+B syntax and :nth-*() pseudo-classes in CSS

  This adds support for the :nth-child(), :nth-last-child(), :nth-of-type(), and :nth-last-of-type() pseudo-classes to esbuild, which has the following consequences:

  • The An+B syntax is now parsed, so parse errors are now reported
  • An+B values inside these pseudo-classes are now pretty-printed (e.g. a leading + will be stripped because it's not in the AST)
  • When minification is enabled, An+B values are reduced to equivalent but shorter forms (e.g. 2n+0 => 2n, 2n+1 => odd)
  • Local CSS names in an of clause are now detected (e.g. in :nth-child(2n of :local(.foo)) the name foo is now renamed)

  /* Original code */
  .foo:nth-child(+2n+1 of :local(.bar)) {
    color: red;
  }
  /* Old output (with --loader=local-css) */
  .stdin_foo:nth-child(+2n + 1 of :local(.bar)) {
  color: red;
  }
  /* New output (with --loader=local-css) */
  .stdin_foo:nth-child(2n+1 of .stdin_bar) {
  color: red;
  }

• Adjust CSS nesting parser for IE7 hacks (#3272)

  This fixes a regression with esbuild's treatment of IE7 hacks in CSS. CSS nesting allows selectors to be used where declarations are expected. There's an IE7 hack where prefixing a declaration with a * causes that declaration to only be applied in IE7 due to a bug in IE7's CSS parser. However, it's valid for nested CSS selectors to start with *. So esbuild was incorrectly parsing these declarations and anything following it up until the next { as a selector for a nested CSS rule. This release changes esbuild's parser to terminate the parsing of selectors for nested CSS rules when a ; is encountered to fix this edge case:

  /* Original code */
  .item {
    *width: 100%;
    height: 1px;
  }
  /* Old output */
  .item {
  *width: 100%; height: 1px; {
  }
  }
  /* New output */
  .item {
  *width: 100%;
  height: 1px;
  }
