purescript-flare

After reading MDN's comparison of and , it seems clear that is sufficient for this use case, while is unsupported in Internet Explorer.

I have been browsing around for creating user interfaces in purescript, and I think I like this library the most because of its simplicity, good job! I have run into a problem that I can't resolve on my own. I have a situation in which I have a past dependent state that is modified by the input. That is no problem except the state also influences what kinds of controls appear on the screen. That is the tricky part. For a concrete example, I want to make a program that visualizes a JSON file, by drawing shapes, and the shapes can be dragged around and stuff. This already works, I have used the signals from purescript-signal. However, I can't really do what I want. The only way I can think of doing it is by creating a channel for the state, subscribing and creating a signal, and combining it with the input signal, and using innerFlare to hide and make elements appear. I think this would work, but I would need to perform effects inside the function. I have found a function that would allow me to do what I want in Signal.Effect. It is called foldEffect, and it does exactly what I want. I could implement it, but I need to deconstruct the UI and Flare types. The implementation would be something like Will you accept a pull request with this new feature? If you know of a simpler way of doing what I want, please let me know. For a simpler example of my problem, consider the following simplified use case: You have a button that says "INC" and a number. If you press "INC" the number will increase. When the number hits 10, a new button will appear that says "RESET". If you press it the number will reset to 0, and the "RESET" button will disappear. Thanks

This is needed for functionality described in this issue: https://github.com/sharkdp/purescript-flare/issues/33
