Usage

import { Cl } from '@stacks/transactions';

Cl.stringify(Cl.uint(100));
// 'u100'

Cl.stringify(Cl.tuple({ id: Cl.some(Cl.uint(1)) }));
// '{ id: (some u1) }'

// With indentation (2 spaces)
Cl.stringify(Cl.tuple({ id: Cl.some(Cl.uint(1)), name: Cl.stringAscii('hello') }), 2);
// '{
//   id: (some u1),
//   name: "hello"
// }'

Notes

• Tuple keys are sorted alphabetically in the output.

• The optional space parameter controls indentation for nested structures.
