Error When Passing Inline Array Or Dict To Tag

[mikebronner]

Steps to reproduce:

1. Create a new vapor project: vapor new test-inline-array cd test-inline-array vapor xcode -y

2. Add Leaf to Package.swift:

   // swift-tools-version:4.1
   import PackageDescription
   
   let package = Package(
     name: "test",
     dependencies: [
         .package(url: "https://github.com/vapor/vapor.git", from: "3.0.4"),
         .package(url: "https://github.com/vapor/leaf.git", from: "3.0.0-rc.2"),
     ],
     targets: [
         .target(name: "App", dependencies: ["Leaf", "Vapor"]),
         .target(name: "Run", dependencies: ["App"]),
         .testTarget(name: "AppTests", dependencies: ["App"])
     ]
   )

3. Register Leaf in configure.swift (and import Leaf at the top of the file):

   try services.register(LeafProvider())
   config.prefer(LeafRenderer.self, for: ViewRenderer.self)

4. Register the test route in routes.swift:

   router.get("test", use: TestController().index)

5. Create the controller in /Sources/App/Controllers/TestController.swift:

   import Vapor
   
   final class TestController {
     func index(_ request: Request) throws -> Future<View> {
         return try request.view().render("test.leaf")
     }
   }

6. Create a new view file: /Resources/Views/test.leaf
7. Paste the following content:

   Hello!
   #count(["class", "test"])

8. Build and run the test app, open browser to: http://localhost:8080/test.
9. The following error is displayed:

   {"error":true,"reason":"Expected ')' got '[' (\/Users\/mike\/Developer\/test\/Resources\/Views\/test.leaf line: 1 column: 31 range: 40..<40)"}

Updated leaf page to not include ConvertToTemplateData class, I was just testing possible solutions.

Moving this to: https://github.com/vapor/leaf/issues/121. TemplateKit only handles serialization. Leaf is responsible for parsing the files.

Thanks ... wasn't sure.

No worries. Thanks for reporting! :)
