Taus 52cdf59f27 unified: Port function, call, and member-access rules to swift-syntax
Retarget function declarations, calls, member access, and control
transfer to the swift-syntax AST, output unchanged:

- `functionDecl` -> `function_declaration` (parameters and return type
  nest under `signature`; the body is a `codeBlock`). A bodyless
  function (a protocol requirement) still emits an empty `block`.
- `functionParameter` -> `parameter`: two names give the external label
  and internal name, one name just the internal name; the default value
  is handled inline, so the `ctx.default_value` threading (and its
  `SwiftContext` field) is removed. The declared type is dropped: in the
  tree-sitter path the untyped-parameter rule was ordered first and
  shadowed the typed one, so the baseline emits no parameter type.
- A function reference spelled with argument labels (`f(x:y:z:)`) is a
  `declReferenceExpr` with `argumentNames`; it is mapped to
  `unsupported_node` (matched before the bare-name rule) so downstream
  QL isn't handed a malformed reference, as in the tree-sitter path.
- `functionCallExpr` -> `call_expr` (a trailing closure becomes a final
  unlabelled argument); `labeledExpr` -> `argument`;
  `memberAccessExpr` -> `member_access_expr` (base-ful matched before
  leading-dot).
- `returnStmt`/`breakStmt`/`continueStmt`/`throwStmt` ->
  `return_expr`/`break_expr`/`continue_expr`/`throw_expr`, collapsing
  the labelled/unlabelled variants via optional captures.

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 code in this repository is licensed under the MIT License by GitHub.

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.
