双向绑定机制 OK。
节点系统,我仍然认为注入节点树更妥当,因为响应机制是全局的(所有节点树都能够响应同一信号),而节点树是局部的(不同节点树之间不能发生干扰),后者不应该为了所谓的“一致性”而以相同方式(全局变量)实现。

全局变量的使用沿袭于SolidJS, 由于js是单线程语言,并且Solid作为UI框架是始终会在主线程进行状态跟踪的,所以全局变量是ok的。
现在考虑到有可能会拓展到更多情景,需要因地制宜。
不过关于节点树的方式,有一些问题需要探讨:
- 节点树之间不能产生冲突,那么响应机制的currentComputation是否也要绑定到节点树上面,同时,目前的响应式机制依赖于单个线程和全局变量访问,而一旦绑定,对于单个树的操作,也会受到限制(可以配套一个eventloop来处理)。
- 节点树的方式大概需要怎么设计,包括节点树的创建和提供,节点树会有哪些操作,节点树之间的交互(比如嵌套?)

鉴于目前没有更多人参与,先采用NodeTree的方案。
那么我们目前需要实现几点:
- NodeTree的设计
interface NodeTree{
val currentNode:Node
//TODO
//是否要实现树的遍历,遍历方式是通过添加Node.parent和Node.children还是全部通过NodeTree维护(比如NodeTree里面维护一个数据结构,存储每个节点的parent和children)
//节点的创建和删除依赖于上述遍历方式的实现
}
- NodeTree的提供
选择在最外层包裹一个常规的提供NodeTree的函数是否可行?
fun factory(tree:NodeTree, block:@Component ()->Unit){
error("intrinsic implemention")
}
- 和Computation的集成
由于响应式限制在单线程环境,那么有很大可能NodeTree需要与其集成
假定我们把computation放在NodeTree中。
会涉及到一个问题:
Signal等响应式原语如何获取currentComputation? 集成后,如果要获取它,需要先获取NodeTree,意味着signal.value的get属性需要带上注解,它将只能在Component函数中使用,这个影响大吗?虽然Compose基本也是将state用在Composable函数中,但不确定在konify中对其他场景是否同样适用(如果这个矛盾无法调和,那么将还是将以UI为主,暂时不考虑UI以外的情景)
