import {withKnobs} from '@storybook/addon-knobs';
import {Provider as StyletronProvider} from 'styletron-react';
import {Client as Styletron} from 'styletron-engine-atomic';

import loadStories from '../.storybook-base/loadStories.js';
import {ThemeProvider} from '../src/styles';
import {LightThemeMove} from '../src/themes';

withOptions({
  name: 'baseui',
  url: 'https://github.com/uber-web/baseui',
});

setOptions({
  theme: {
    ...themes.normal,

    successColor: LightThemeMove.colors.positive,
    warningColor: LightThemeMove.colors.warning,
    failColor: LightThemeMove.colors.negative,
  },
});

const engine = new Styletron();

// this should be first decorator to avoid extra code to be parsed here
addDecorator(withInfo);

addDecorator(withKnobs);
addDecorator(checkA11y);
