Prepare

monaco-dolphindb need some external resources to work properly, you should copy follow things from node_modules to your project:

• onig.wasm from vscode-oniguruma/release/onig.wasm
• docs.en.json and docs.zh.json from dolphindb

Breaking change in docs.en.json and docs.zh.json

In v0.1.0, we upgrade the struct of docs.xx.json, so you should use dolphindb library newer than v2.0.????

monaco-dolphindb	dolphindb
> 0.1.0	>= 2.0.????
< 0.1.0	<= 2.0.????

Usage

Vanilla

import { registerDolphinDBLanguage } from 'monaco-dolphindb';
import { loadWASM } from 'vscode-oniguruma';

// load wasm
await loadWASM(await fetch('/onig.wasm'));

await registerDolphinDBLanguage(Monaco, {
  docs: '/docs.zh.json',
});

const editor = Monaco.editor.create(document.getElementById('root')!, {
  value: '1 + 2',
  language: 'dolphindb',
  ...settings,
});

React

PS: monaco-dolphindb/react include some special logic to make it easy to use for our internal project, so it may not fit your project, you can copy the source code and modify it to fit your project.

MonacoDolphinDBEditor

import { loadWASM } from 'vscode-oniguruma';
import { MonacoDolphinDBEditor } from 'monaco-dolphindb/react';
import * as monaco from 'monaco-editor';
import { loader } from '@monaco-editor/react';
import * as ReactDOM from 'react-dom/client';

loader.config({
  monaco,
});

async function beforeMonacoEditorInit() {
  return loadWASM(await fetch('/onig.wasm'));
}

function App() {
  const [value, setValue] = React.useState('1 + 2');

  const onChange = React.useCallback((value?: string) => {
    setValue(value ?? '');
  }, []);

  return (
    <MonacoDolphinDBEditor
      dolphinDBLanguageOptions={{
        docs: '/docs.zh.json',
        language: 'zh',
      }}

        acceptSuggestionOnEnter: 'on',
      }}
      value={value}
      onChange={onChange}
    />
