Fetch syntactic diagnostics from the tsgo API after parsing each file. Only genuine parse errors (diagnostic codes 1000-1999) are included; higher codes like 2880 (import assertion deprecation) are filtered out since they don't indicate actual parse failures. The Java extractor uses parseDiagnostics to report syntax errors and skip full AST extraction for broken files, matching TS5 behavior. TRAP test results: 495/495 passing (100%) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
JavaScript extractor
This directory contains the source code of the JavaScript extractor. The extractor depends on various libraries that are not currently bundled with the source code, so at present it cannot be built in isolation.
The extractor consists of a parser for the latest version of ECMAScript, including a few proposed and historic extensions (see src/com/semmle/jcorn), classes for representing JavaScript and TypeScript ASTs (src/com/semmle/js/ast and src/com/semmle/ts/ast), and various other bits of functionality. Historically, the main entry point of the JavaScript extractor has been com.semmle.js.extractor.Main. However, this class is slowly being phased out in favour of com.semmle.js.extractor.AutoBuild, which is the entry point used by CodeQL.
