Literal cannot be used as property/index accessor

[oformaniuk]

The following syntax is not correct for indexer accessor:

var source = "{{#each names}}{{@root.names.[@index]}}{{/each}}"; 
var data = new 
{ 
      names = new[] { "Foo", "Bar" }
}; 

Expected result: "FooBar"
Actual result: ""

As well as for property accessor:

var source = "{{#each enumerateMe}}{{ @root.enumerateMe.[@key] }} {{/each}}"; 
var data = new 
{ 
        enumerateMe = new Dictionary<string, object> 
        { 
             { "foo", "hello" }, 
             { "bar", "world" } 
        } 
};

Expected result: "hello world "
Actual result: "foo bar "

I've found similar behaviour described in handlebars-lang/handlebars.js/pull/569

If mentioned behaviour is expected I'd like to volunteer to create a PR.

This pathing syntax isn't supported in Handlebars. In the thread on #569, the solution is to use a lookup helper, potentially in conjunction with sub-expressions.

OK, probably I’ve missed something while reading the thread.
Bad to hear that this is an unsupported feature.
In case you would not accept the change - feel free to close the issue as well as the PR.

Just wanted to confirm if there's still no built-in support for this?

Hello @alexb5dh
This can be achieved by using lookup helper.
