Parse script using position 0 of cursor

import { ParserController } from '../index';
const query: string = 'select * from mytable; insert into mytable ("col1") VALUES("blablabla") select * from mytable2;table2;';
const q: string = ParserController.getInstance().getQuery(query, 0, 0);
console.log(q); // select * from mytable

Parse script using position of cursor from 0 until 22 (selected text with mouse)

const q: string = ParserController.getInstance().getQuery(query, 0, 22);
console.log(q); // select * from mytable;

Parse script using position 23 of cursor

const q: string = ParserController.getInstance().getQuery(query, 23, 23);
console.log(q); // insert into mytable ("col1") VALUES("blablabla") select * from mytable2

Search table

const tables: string[] = [];
tables.push('table_1');
tables.push('table_2');
tables.push('table_3');
HelperController.getInstance().setTables(tables);
HelperController.getInstance().setColumns([]);
const result: string[] = HelperController.getInstance().searchTables('able');
console.log(result); // ['table_1', 'table_2', 'table_3']
result = HelperController.getInstance().searchTables('_2');
console.log(result); // ['table_2']

Search snippet

const result: string[] = HelperController.getInstance().searchSnippet('select');
console.log(result); // ['select * from $1']
result = HelperController.getInstance().searchSnippet('select', ['tablexpto']);
console.log(result); // ['select * from tablexpto']

Identify tags and get colors

const result: any = IdentifierController.getInstance().search('select');
console.log(result); // {tag: 'select', color: 'blue'}
const color: string = IdentifierController.getInstance().colorize('select');
console.log(color); // 'blue'

Roadmap

• Add query parser to identify selected query block (Done)
• Add tables, columns quick search (Done)
• Add snippets with quick search (Done)
• Snippets with properties replace (Done)
• Identify tags, and assign properties, like color (Done)
• SQL validator (Backlog)
