 * `physicalFilename`: (`string`) When linting a file, it provides the full path of the file on disk without any code block information. When linting text, it provides the value passed to `—stdin-filename` or `<text>` if not specified.
 * `cwd`: (`string`) The `cwd` option passed to the [Linter](../integrate/nodejs-api#linter). It is a path to a directory that should be considered the current working directory.
 * `options`: (`array`) An array of the [configured options](../use/configure/rules) for this rule. This array does not include the rule severity (see the [dedicated section](#accessing-options-passed-to-a-rule)).
+* `sourceCode`: (`object`) A `SourceCode` object that you can use to work with the source that was passed to ESLint (see [Accessing the Source Code](#accessing-the-source-code)).
 * `settings`: (`object`) The [shared settings](../use/configure/configuration-files#adding-shared-settings) from the configuration.
 * `parserPath`: (`string`) The name of the `parser` from the configuration.
 * `parserServices`: (`object`) Contains parser-provided services for rules. The default parser does not provide any services. However, if a rule is intended to be used with a custom parser, it could use `parserServices` to access anything provided by that parser. (For example, a TypeScript parser could provide the ability to get the computed type of a given node.)

 * `getScope()`: (**Deprecated:** Use `SourceCode#getScope(node)` instead.) Returns the [scope](./scope-manager-interface#scope-interface) of the currently-traversed node. This information can be used to track references to variables.
 * `getSourceCode()`: (**Deprecated:** Use `context#sourceCode` instead.) Returns a `SourceCode` object that you can use to work with the source that was passed to ESLint (see [Accessing the Source Code](#accessing-the-source-code)).

 * `markVariableAsUsed(name)`: (**Deprecated:** Use `SourceCode#markVariableAsUsed(name, node)` instead.)  Marks a variable with the given name in the current scope as used. This affects the [no-unused-vars](../rules/no-unused-vars) rule. Returns `true` if a variable with the given name was found and marked as used, otherwise `false`.
 * `report(descriptor)`. Reports a problem in the code (see the [dedicated section](#reporting-problems)).
