add-args

❌ Example of incorrect code

module.exports = {
    TSPropertySignature(path) {
        const {optional} = path.node;
        print('__key');
        maybe.print(optional, '?');
    },
};

✅ Example of correct code

module.exports = {
    TSPropertySignature(path, {print, maybe}) {
        const {optional} = path.node;
        print('__key');
        maybe.print(optional, '?');
    },
};

apply-computed-print

❌ Example of incorrect code

print(path.get('block'));

✅ Example of correct code

print('__block');

remove-args

❌ Example of incorrect code

print.indent(is);

✅ Example of correct code

print.indent();

declare

❌ Example of incorrect code

isIdentifier();

test('', (t) => {
    t.print(fixture.returnStatement);
});

✅ Example of correct code

const {types} = require('@putout/babel');
const {createTest} = require('#test');

const {test, fixture} = createTest(__dirname);
const {isIdentifier} = types;

isIdentifier();

test('', (t) => {
    t.print(fixture.returnStatement);
});

remove-legacy-test-declaration

-const {printExtension} = require('../../../test/printer');
-const {readFixtures} = require('../../../test/fixture');
-
-const fixture = readFixtures(__dirname);
-
-const test = extend({
-    print: printExtension,
