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 supports various SQL languages and the corresponding advanced features for the Big Data field.

Integrating

• Integrating the ESM version of Monaco SQL Languages

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/esm/languages/mysql/mysql.contribution';
   import 'monaco-sql-languages/esm/languages/flink/flink.contribution';
   import 'monaco-sql-languages/esm/languages/spark/spark.contribution';
   import 'monaco-sql-languages/esm/languages/hive/hive.contribution';
   import 'monaco-sql-languages/esm/languages/trino/trino.contribution';
   import 'monaco-sql-languages/esm/languages/pgsql/pgsql.contribution';
   import 'monaco-sql-languages/esm/languages/impala/impala.contribution';
   
   // Or you can import all language contributions at once.
   // import 'monaco-sql-languages/esm/all.contributions';

2. Setup language features

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

   import { LanguageIdEnum, setupLanguageFeatures } from 'monaco-sql-languages';
   
   setupLanguageFeatures(LanguageIdEnum.FLINK, {
       completionItems: {
           enable: true,
           triggerCharacters: [' ', '.'],
           completionService: //... ,
       }
   });

   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, // syntax context info at caretPosition
       entities // tables, columns in the syntax context of the editor text
   ) {
       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(LanguageIdEnum.FLINK, {
       completionItems: {
           enable: true,
           completionService: //... ,
       }
   });

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

   import { LanguageIdEnum } from 'monaco-sql-languages';
   
   monaco.editor.create(document.getElementById('container'), {
       value: 'select * from tb_test',
       language: LanguageIdEnum.FLINK // languageId
   });

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.*.
