Asger F f3b27a56b1 TypeScript-Go wrapper: binary AST decoder, JSON converter, and tokenizer
Implement the core components for translating tsgo's binary AST format
into the JSON format expected by the Java extractor:

- decoder.go: Binary AST format parser with random-access node accessors
  (kind, pos, end, flags, children, strings, extended data)
- converter.go: Walks decoded AST and produces JSON matching Node.js
  wrapper output (augmented , , , ,
  isTypeOnly, HeritageClause token, TypeOperator operator)
- childprops.go: Maps ~100 SyntaxKind names to ordered child property
  name lists for correct bitmask-to-property assignment
- scanner.go: TypeScript tokenizer producing  array with rescan
  support for regex, template, and greater-than disambiguation

Update metadata.go with correct TS7 SyntaxKind iota values and export
metadata functions. Wire decoder+converter through TsgoParser.Parse().

Validation test passes: all 421 diffs are expected TS5-vs-TS7 numeric
kind/flags/token/operator value differences. Zero structural diffs.

CodeQL

This open source repository contains the standard CodeQL libraries and queries that power GitHub Advanced Security and the other application security products that GitHub makes available to its customers worldwide.

How do I learn CodeQL and run queries?

There is extensive documentation about the CodeQL language, writing CodeQL using the CodeQL extension for Visual Studio Code and using the CodeQL CLI.

Contributing

We welcome contributions to our standard library and standard checks. Do you have an idea for a new check, or how to improve an existing query? Then please go ahead and open a pull request! Before you do, though, please take the time to read our contributing guidelines. You can also consult our style guides to learn how to format your code for consistency and clarity, how to write query metadata, and how to write query help documentation for your query.

For information on contributing to CodeQL documentation, see the "contributing guide" for docs.

The CodeQL CLI (including the CodeQL engine) is hosted in a different repository and is licensed separately. If you'd like to use the CodeQL CLI to analyze closed-source code, you will need a separate commercial license; please contact us for further help.

Visual Studio Code integration

If you use Visual Studio Code to work in this repository, there are a few integration features to make development easier.

CodeQL for Visual Studio Code

You can install the CodeQL for Visual Studio Code extension to get syntax highlighting, IntelliSense, and code navigation for the QL language, as well as unit test support for testing CodeQL libraries and queries.

Tasks

The .vscode/tasks.json file defines custom tasks specific to working in this repository. To invoke one of these tasks, select the Terminal | Run Task... menu option, and then select the desired task from the dropdown. You can also invoke the Tasks: Run Task command from the command palette.
