Monaco SQL Languages

English | 简体中文

This project is based on the SQL language project of Monaco Editor, which was forked from the monaco-languages.

The difference is that Monaco SQL Languages has integrated with various SQL languages for the Big Data field, such as FlinkSQL, SparkSQL, HiveSQL, and others.

In addition, Monaco SQL Languages provides SQL syntax validation and CodeCompletion feature for these languages via dt-sql-parser.

Monaco SQL Languages plan to support more types of SQL Languages in the future. If you need some SQL Languages that are not currently supported, you can contact us at github.

Installing

npm install monaco-sql-languages

Tips: Monaco SQL Languages is only guaranteed to work stably on monaco-editor@0.31.0 for now.

Integrating

• Integrating the ESM version of Monaco SQL Languages
• Solving the problem of integrating

Usage

1. Import language contributions

   Tips: If integrated via MonacoEditorWebpackPlugin, it will help us to import contribution files automatically. Otherwise, you need to import the contribution files manually.

   import 'monaco-sql-languages/out/esm/mysql/mysql.contribution';
   import 'monaco-sql-languages/out/esm/flinksql/flinksql.contribution';
   import 'monaco-sql-languages/out/esm/sparksql/sparksql.contribution';
   import 'monaco-sql-languages/out/esm/hivesql/hivesql.contribution';
   import 'monaco-sql-languages/out/esm/trinosql/trinosql.contribution';
   import 'monaco-sql-languages/out/esm/impalasql/impalasql.contribution';
   import 'monaco-sql-languages/out/esm/pgsql/pgsql.contribution';
   
   // Or you can import all language contributions at once.
   // import 'monaco-sql-languages/out/esm/monaco.contribution';
   

2. Setup language features

   You can setup language features via setupLanguageFeatures. For example, disable code completion feature of flinkSQL language.

   import {
       setupLanguageFeatures,
       LanguageIdEnum,
   } from 'monaco-sql-languages';
   
   setupLanguageFeatures({
       languageId: LanguageIdEnum.FLINK,
       completionItems: false
   })
   

   By default, Monaco SQL Languages only provides keyword autocompletion, and you can customize your completionItem list via completionService.

   import { languages } from 'monaco-editor/esm/vs/editor/editor.api';
   import {
       setupLanguageFeatures,
       LanguageIdEnum,
       CompletionService,
       ICompletionItem,
       SyntaxContextType
    } from 'monaco-sql-languages';
   
   const completionService: CompletionService = function (
       model,
       position,
       completionContext,
       suggestions
   ) {
       return new Promise((resolve, reject) => {
           if (!suggestions) {
               return Promise.resolve([]);
           }
           const { keywords, syntax } = suggestions;
           const keywordsCompletionItems: ICompletionItem[] = keywords.map((kw) => ({
               label: kw,
               kind: languages.CompletionItemKind.Keyword,
               detail: 'keyword',
               sortText: '2' + kw
           }));
   
           let syntaxCompletionItems: ICompletionItem[] = [];
   
           syntax.forEach((item) => {
               if (item.syntaxContextType === SyntaxContextType.DATABASE) {
                   const databaseCompletions: ICompletionItem[] = []; // some completions about databaseName
                   syntaxCompletionItems = [...syntaxCompletionItems, ...databaseCompletions];
               }
               if (item.syntaxContextType === SyntaxContextType.TABLE) {
                   const tableCompletions: ICompletionItem[] = []; // some completions about tableName
                   syntaxCompletionItems = [...syntaxCompletionItems, ...tableCompletions];
               }
           });
   
           resolve([...syntaxCompletionItems, ...keywordsCompletionItems]);
       });
   };
   
   setupLanguageFeatures({
       languageId: LanguageIdEnum.FLINK,
       completionService: completionService,
   })
   

3. Create the Monaco Editor instance and specify the language you need

   monaco.editor.create(document.getElementById('container'), {
       value: 'select * from tb_test',
       language: 'flinksql' // you need
   });
   

Monaco Theme

Monaco SQL Languages plan to support more themes in the future.

Monaco SQL Languages provides built-in Monaco Theme that is named vsPlusTheme. vsPlusTheme inspired by vscode default plus colorTheme and it contains three styles of themes inside:

• darkTheme: inherited from Monaco built-in Theme vs-dark;
• lightTheme: inherited from Monaco built-in Theme vs;
• hcBlackTheme: inherited from Monaco built-in Theme hc-black;

Use Monaco SQL Languages built-in vsPlusTheme

import { vsPlusTheme } from 'monaco-sql-languages';
import { editor } from 'monaco-editor';

// import themeData and defineTheme, you can customize the theme name, e.g. sql-dark
editor.defineTheme('sql-dark', vsPlusTheme.darkThemeData);
editor.defineTheme('sql-light', vsPlusTheme.lightThemeData);
editor.defineTheme('sql-hc', vsPlusTheme.hcBlackThemeData);

// specify the theme you have defined
editor.create(null as any, {
    theme: 'sql-dark',
    language: 'flinksql'
});

Customize your own Monaco theme

import { TokenClassConsts, postfixTokenClass } from 'monaco-sql-languages';

// Customize the various tokens style
const myThemeData: editor.IStandaloneThemeData = {
    base: 'vs-dark',
    inherit: true,
    rules: [
        { token: postfixTokenClass(TokenClassConsts.COMMENT), foreground: '6a9955' },
        { token: postfixTokenClass(TokenClassConsts.IDENTIFIER), foreground: '9cdcfe' },
        { token: postfixTokenClass(TokenClassConsts.KEYWORD), foreground: '569cd6' },
        { token: postfixTokenClass(TokenClassConsts.NUMBER), foreground: 'b5cea8' },
        { token: postfixTokenClass(TokenClassConsts.STRING), foreground: 'ce9178' },
        { token: postfixTokenClass(TokenClassConsts.TYPE), foreground: '4ec9b0' }
    ],
    colors: {}
};

// Define the monaco theme
editor.defineTheme('my-theme', myThemeData);

postfixTokenClass is not required in most cases, but since Monaco SQL Languages has tokenPostfix: 'sql' internally set for all SQL languages, in some cases your custom style may not work if you don't use postfixTokenClassClass to handle TokenClassConsts.*.
