Highlights

@tsrx/oxc-core-compat now matches @tsrx/core 0.5.2 on leonidaz's remaining conformance reports. With this release the oxc repository has no open issues.

  • Lone surrogates (a UTF-16 surrogate without its pair) are kept as written in .js, .jsx, .ts and .tsx files. This applies to strings, regex patterns, directives, JSX attributes and text, template text and comments. They used to become U+FFFD (#139, #177).
  • Template text spans the text alone. In .tsrx, .tsx and .jsx files, a TemplateElement no longer includes the backtick or the ${/} next to its text, and value.raw no longer picks up those delimiters next to a lone surrogate (#140, #177).
  • Errors have core's shape (#142, #176):
    • A thrown SyntaxError ends its message with (line:column) and has loc as { line, column }, plus pos and raisedAt, as acorn gives them.
    • Mistakes core reports itself (TSRX2011, TSRX2012, TSRX1004, TSRX2001, redeclarations and others) throw a plain Error with fileName, end, type: "fatal" and a span loc.
    • Malformed directives get core's codes and positions, including the two that had none: @if with no condition is TS1359, and an @ in a @switch body is TS1012.
    • An element a template ends before its closing tag is Unclosed tag '<div>'. Expected '</div>' before end of template. at the template's }.
  • After a bare @, the error is at the token that follows it, even when a later structural error also exists, as in core (#175, #176).
  • The Markless drop-in suite runs in CI as pnpm run test:markless-dropin. Its three stale expectations now match core 0.5.2 (#143, #174).

Behaviour change

Thrown errors from parseModule look different:

  • Messages gain the (line:column) suffix.
  • loc is { line, column } instead of { start, end }.
  • The native messages malformed TSRX at byte … and unterminated JSX element … are replaced by core's wording.

Collected errors keep their span shape. Lint, format and the editor read the Rust diagnostics and are unchanged.

  • compat: Keep a lone surrogate as written in .js, .jsx, .ts and .tsx files, and span template text alone, as @tsrx/core 0.5.2 does (#139, #140) (#139, #140)
  • compat: Read past comments, class heritage, and nested template literals when placing core's errors (#142)
  • compat: Throw at the token after a bare @ before any later error, as @tsrx/core 0.5.2 does (#175)
  • compat: Tell a class body from a later block, a class string, and a comparison in heritage (#142)
  • compat: Read a class head past comments and strings (#142)
