Asger F 93deb33a2a Fix validation script to tolerate expected TS7 kind/flags diffsTS5
The shell validation script now uses a structural comparison that
ignores expected numeric differences in kind/flags/token/operator
values between TS5 and TS7. Only truly structural diffs cause failure.

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.
