// { 'userId': /^\w+$/, 'messageId': /^\d+$/ }
export type ParameterPatterns = { [parameterName: string]: RegExp; };

// { 'userId': 'john', 'messageId': '123' }
export type Parameters = { [parameterName: string]: string; };

// '/users/john/messages/123'
export type Path = string;

// assert.deepEqual(
// params('/users/john/messages/123'),
// { 'userId': 'john', 'messageId': '123' }
// );
export type ParametersFn = (path: Path) => Parameters | null;

// assert.deepEqual(
// path({ 'userId': 'john', 'messageId': '123' }),
// '/users/john/messages/123'
// );
export type PathFn = (params: Parameters) => Path | null;

// const { params, path } = bath('/users/{userId}/messages/{messageId}')
export type Bath = (
template: PathTemplate,
patterns?: ParameterPatterns
) => { names: ParameterName[]; path: PathFn; params: ParametersFn; };
