示例1: expression_parse
var awaiters = arr.map(async str => {
var ast = expression_parse('"I`m " + user->name + user->name');
eq_(ast.async, true);
var user = {name: 'John'};
var result = await expression_eval(ast, { user });
deepEq_(result, 'I`m JohnJohn');
});示例2: require
import { expression_eval, expression_parse } from '@project/expression/src/exports';
import { listeners_on, listeners_off } from '@core/util/listeners'
import sinon = require('sinon');
UTest({
$config: {
breakOnError: true
},
async 'should parse and evaluate simple expression' () {
var ast = expression_parse('await someFn()');
eq_(ast.async, true);
var someFn = sinon.spy(async function(){
return { foo: 'Foo'};
})
var dfr = expression_eval(ast, { someFn })
is_(dfr.then, 'Function');
var result = await dfr;
deepEq_(result, {foo: 'Foo'});
