Pitfalls

Since grouped binding notation is syntactically ambiguous, it is parsed as an object definition.

// (ui_object_definition type_name: (identifier "Button") ...)
Button {
    // (ui_object_definition type_name: (identifier "icon") ...)
    icon { source: "foo.png"; color: "transparent" }
}

Building

Use the master branch, which contains all generated files.

$ git checkout master
$ npm install
$ cargo build --release

Hacking

Use the dev branch, but you'll first need to run npm install in the master branch.

$ git checkout master
$ npm install
$ git checkout dev

Generate code and run tests:

$ make generate tests

Make sure example QML files can be parsed:

$ make fetch-examples parse-examples
