Retarget property accessors to the swift-syntax AST, output unchanged.
An accessor-bearing `variableDecl` publishes the property name/type into
`ctx`; a computed property (`var v: T { get set }`) emits accessors
carrying the type, while a stored property with observers (`var x = e {
didSet {…} }`) emits the backing `variable_declaration` first.
swift-syntax models get/set/willSet/didSet uniformly as `accessorDecl`,
so a single `accessorDecl` rule — with an optional body distinguishing a
computed accessor from a bodyless protocol requirement — replaces the
tree-sitter grammar's separate computed-getter/setter/modify,
willset/didset, and getter-/setter-specifier rules.
The tree-sitter protocol property and function requirement rules
(`protocol_property_declaration`, `protocol_function_declaration`) are
dropped: swift-syntax models those requirements as ordinary
`variableDecl`s (with bodyless accessors) and `functionDecl`s, already
handled by the general rules.

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.
