RunKit Link showing full stack trace

const { State } = require('markup-it');
const markdown = require('markup-it/lib/markdown');

const state = State.create(markdown);
const document = state.deserializeToDocument('Hello **World**');

I've tried with immutable@3.8.1 and immutable@3.8.2, and @gitbook/slate@0.34.10 and @gitbook/slate@0.34.7.

the same to me, any updates? @tolmasky

I've not gotten it to work. Sticking with remark for now, but want to eventually switch to markup-it for template support.

Hi, I would like to try this compiler (and then add support for textile (JIRA format)). But I got stuck on this error.
Is there any progress? @Soreine

@tolmasky Indeed, it doesn't work.

markup-it/lib/markdown is using ES6 Modules:

import block from './blocks';
import inline from './inlines';
import document from './document';

export default {
    document: [document],
    inline,
    block
};

Once converted by Babel into CommonJS, the exported object becomes:

{
   "default": {
      "document": ...,
      "inline": ...,
      "block": ...
   }
}

So, in order to make it works you can either replace State.create(markdown) by State.create(markdown.default) or use ES6 modules:

import { State } from 'markup-it'
import markdown from 'markup-it/lib/markdown'
import { Map, List } from 'immutable'

const state = State.create(markdown);
const doc = state.deserializeToDocument('Hello **World**');
