[elm-discuss] Re: Subscribe to a model value then call update function when condition is met

I'm sorry. Don't why your answer wasn't loaded that day. Aren't "set and unset whenever processing is started/finished" side-effects? We can do that easily in imperative languages but all functions in ELM are pure. Vào 03:55:33 UTC+7 Thứ Ba, ngày 11 tháng 10 năm 2016, OvermindDL1 đã viết: > >

But if I do it this way, it's gonna return both the player's move and the AI's move at the same time. What I want to have is that the game displays the player's move THEN call minimax function on current model and THEN display the AI's move Vào 06:41:14 UTC+7 Thứ Tư, ngày 12 tháng 10 năm 2016,

[elm-discuss] Re: Subscribe to a model value then call update function when condition is met

It's a common misunderstanding that every discrete change to a model must originate from a different message. In general messages are for expressing what is allowed to happen in your application as a result of outside behavior like user input and server responses, whereas you want to run your

[elm-discuss] Elm GUI component library

I would love to use ELM as my client side language. However, a show stopper at the moment is the lack of a decent ELM GUI component library. Currently I am using webix an extremely simple to use library to create a complex one page application. I think it would be a great

[elm-discuss] Re: Pure Elm contenteditable rich text editor

This is also what I do for a CMS'ish style of interface in something at work, using elm-markdown to render a real-time view of what is being created. Even pre-markdown back in decades past I still opted two have two panes, one where (at the time) html was put in, and the other showing the

Re: [elm-discuss] Re: Html.Keyed

Eh, not really, it is precisely the same issues as you would have with, for example, React, or any of the other JS libraries that use virtual-doms. Just an aspect of how web browser DOM's are made due to backwards compatibility with a lot of old sites over a period of many many decades. Have

[elm-discuss] Re: Pure Elm contenteditable rich text editor

If your users understand markdown, you could use markdown input and maybe even render a preview. This is what I am doing for a project of mine. (This of course circumvents the problem of writing a rich text editor but might help with your original problem.) Am Montag, 10. Oktober 2016

Re: [elm-discuss] Re: Html.Keyed

I haven't yet dug into the actual example code, but this response goes straight to the issue of continuity of identity that makes things like web components an interesting problem for a functional virtual DOM. Mark P.S. I prototyped a system a few years ago on Cocoa in which view creation was

Re: [elm-discuss] Re: How important is Html.Lazy to performance?

Specifically the server sent a list of records over websocket one at a time (at times a *lot* of records), those were stored pretty much verbatim in the model. I had a field on the model that was just an Int, started at 0, the view rendered the list of those records (just one part of the

Re: [elm-discuss] Re: How important is Html.Lazy to performance?

Interesting. I can understand using a sentinel to force re-rendering but I'm curious as to how your model or view was structured such that it could inhibit re-rendering via laziness. Mark > On Oct 11, 2016, at 8:42 AM, OvermindDL1 wrote: > > Personally I've known it to

[elm-discuss] Re: Html.Keyed

The ticked checkbox is because the user ticked it, it is some of the implicit DOM state. When the view changed to remove a checkbox but it still had another one after, since they were not keyed it just did a 'diff' between states. The vdom has no information on any implicit state in the

[elm-discuss] Html.Keyed

Hi there, Today I raised https://github.com/elm-lang/virtual-dom/issues/37 Given there's no consensus on whether it's a bug, I'm bringing the discussion here. The reason why I think it's a bug is that the second time the view function runs it generates a ticked checkbox, although nowhere in

[elm-discuss] Re: How important is Html.Lazy to performance?

Personally I've known it to help very little (keyed is usually more appropriate), but there have been a few times where it saves significant processing, but at those places I ended up setting it up with a 'sentry' value in a model (just an integer) that I incremented every time I wanted that

[elm-discuss] How important is Html.Lazy to performance?

I was looking back at our first "big" (as in not the tiniest of toys) Elm app and at its tendency to factor the model based on the view hierarchy. This had struck me as a dubious pattern at the time and there is a strong argument voiced by some that one should just stay flat as long as

[elm-discuss] Re: Another documentation item I think is needed

The comparison page you refer to is more a high-level comparison between javascript and elm syntax. It does not look like it is intended to be in-depth. I agree it would be useful to have some docs at some time summing up the pros and cons of List vs Array vs Set vs Dict. But I am not sure that

[elm-discuss] Re: Subscribe to a model value then call update function when condition is met

PS: The subscription to time is useful if you want some sort of timeout or delay between the user move and the AI move. If you want to do the AI move immediately after the user move (without delay), a pattern with a recursive update call (and without subscription) is probably more suited.

In the standard docs, there is some explanation of types here . But no exhaustive list. In practice, I found that I did not need to learn any of the standard types. In contrast to any other language I know, Elm's compiler is really helpful
