Prepare

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

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

Then write some code to load them.

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',
      }}
      beforeInit={beforeMonacoEditorInit}
      options={{
        acceptSuggestionOnEnter: 'on',
      }}
      value={value}
      onChange={onChange}
    />
  );
}

ReactDOM.createRoot(document.getElementById('root')!).render(<App />);

MonacoDolphinDBDiffEditor

import { loadWASM } from 'vscode-oniguruma';
import { MonacoDolphinDBDiffEditor } 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() {
  return (
    <MonacoDolphinDBDiffEditor
      dolphinDBLanguageOptions={{
        docs: '/docs.zh.json',
        language: 'zh',
      }}
      beforeInit={beforeMonacoEditorInit}
      original="1 + 2"
      modified="1 + 3"
    />
  );
}

ReactDOM.createRoot(document.getElementById('root')!).render(<App />);
