Automatiqal filter parser
Description
Small (and very specific) package to parse Automatiqal conditions and covert them to JS.
These condition are quite similar to Qlik Repository filtering format.
Usage
import { parseFilter } from "@informatiqal/filter-parser";
const parsed = parseFilter("(('something' so 'thing' and 1 eq 1) or 3 gt 4)")
Once executed the value of parsed (string) will be:
(('something'.includes('thing') && 1 == 1) || 3 > 4)The returned string can then be evaluated to get the result of it. In the example above the result will be true.
Base path
UNDER DEVELOPMENT Please do not use at the moment!
The main function accepts additional parameter - base path. Extending the example above:
import { parseFilter } from "@informatiqal/filter-parser";
const parsed = parseFilter("(('something' so 'thing' and 1 eq 1) or 3 gt 4)", "myObj")
Will return:
((myObj.something.includes('thing') && myObj.1 == 1) || myObj.3 > 4)Available operators
