Taus 8e6651aa9b unified: Port type-container declarations to swift-syntax
Retarget the nominal type declarations to the swift-syntax AST, output
unchanged.
`classDecl`/`structDecl`/`enumDecl`/`protocolDecl`/`extensionDecl`
each become a `class_like_declaration` tagged with a modifier naming the
declaration keyword, with members drawn from the `memberBlock`; each
`memberBlockItem` unwraps to its contained declaration. `superExpr` maps
to `super_expr`; `self` needs no rule (swift-syntax models it as an
ordinary `declReferenceExpr`, already a `name_expr`).

Following the tree-sitter path (PARITY), the inheritance clause is not
emitted as a `base_type` (the tree-sitter rule captured it positionally,
but the grammar nests it under a field, so it never actually matched);
swift-syntax exposes it cleanly, so that is a correctness improvement to
make once tree-sitter is retired. The tree-sitter grammar's standalone
`self`, dead modifier (`visibility_modifier`, etc.), key-path, and
inheritance-specifier rules are dropped; `#selector`/`#keyPath` (now a
`macroExpansionExpr`) stays an `unsupported_node`.

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.

License

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.
