💻

• Would you like to work on a fix?

How are you using Babel?

Programmatic API (babel.transform, babel.parse)

Input code

const parser = require('@babel/parser');
const traverse = require('@babel/traverse').default;

const ast = parser.parse('const a = #[1]', {
    sourceType: 'module',
    plugins: [
        'recordAndTuple'
    ],
});

traverse(ast, {
    TupleExpression(path) {
        console.log(path.toString());
    }
});

Current and expected behavior

Current beheviour is crash:

/Users/coderaiser/printer/node_modules/@babel/generator/lib/generators/types.js:136
    throw new Error(`${this.format.recordAndTupleSyntaxType} is not a valid recordAndTuple syntax type`);
    ^

Would be great to receive string representation of path.

Environment

Latest versions.

Possible solution

Set default to hash in @babel/generator:

babel/packages/babel-generator/src/index.ts

Line 74 in 61147b7

recordAndTupleSyntaxType: opts.recordAndTupleSyntaxType,
