real-ssql v0.0.5

Super simple query language for matching strings.

Grammar

not-operator: NOT

binary-operator:   AND   OR

text: any non-empty string which is neither not-operator nor binary-operator and doesnt contain parens

expression:   (expression)   not-operator expression   text   expression binary-operator expression

Usage

const ssql = require('real-ssql');

let query = ssql.parse('(hello  OR  world) AND (bar OR baz)');
ssql.match(query, 'world');            //false
ssql.match(query, 'hello');            //false
ssql.match(query, 'hello world');      //false
ssql.match(query, 'world hello');      //false
ssql.match(query, 'world bar hello');  //true
ssql.match(query, 'world baz');        //true
ssql.match(query, 'hello baz');        //true
ssql.match(query, 'hello bar');        //true

Also you can specify your own representation of operators:

let query = parse('(hello  или  world) и (bar или baz)', {
    and: 'и',
    or: 'или',
    not: 'не'
});
ssql.match(query, 'hello world');   //false
ssql.match(query, 'world baz');     //true

ES5 version

This may be needed, for example, in a project created with react-create-app.

import ssql from 'real-ssql/es5';
