eslint: Bug: FlatArrayConfig options cannot be overriden

Environment

Node version: v16.20.0 npm version: v8.19.4 Local ESLint version: Not found Global ESLint version: Not found Operating System: linux 6.5.7-arch1-1

What parser are you using?

Default (Espree)

What did you do?

Configuration 
import * as tsParseForESLint from "@typescript-eslint/parser";

const config = [
  {
    languageOptions: {
      parser: tsParseForESLint,
    },
    files: ["**/*.ts", "**/*.js", "**/*.tsx", "**/*.jsx"],
  },
]

const linter = new Linter({
  configType: "flat",
});
const report = linter.verifyAndFix(code, config, filename);

What did you expect to happen?

I want to be able to override FlatConfigArray options

What actually happened?

There is no option to forward options to FlatConfigArray

Yes, I also think we can close this now.

Starting from ESLint v8.54.0, cwd passed to the Linter constructor is used as config’s basePath. So, for example, this works:

const { Linter } = require("eslint");

const linter = new Linter({
    configType: "flat",
    cwd: "/tmp" // <-
});

const code = "foo";
const config = [{
    files: ["**/*.ts"],
    rules: {
        "no-undef": "error"
    }
}];
const filename = "/tmp/myfile.ts";

const report = linter.verifyAndFix(code, config, filename);

console.log(report);

/*

    {
        fixed: false,
        messages: [
            {
                ruleId: 'no-undef',
                severity: 2,
                message: "'foo' is not defined.",
                line: 1,
                column: 1,
                nodeType: 'Identifier',
                messageId: 'undef',
                endLine: 1,
                endColumn: 4
            }
        ],
        output: 'foo'
    }
