I'm confused - you say it's designed for mobile - but the link requires flash and therefore I'm unable to use it on mobile.
- fao_ 11y ago
  I assume it's just the web demo that won't work on mobile.
  - icebraining 11y ago
    Yeah, it's a native app, not a web app: http://www.tapirgames.com/App/IfLoop http://www.tapirgames.com/App/IfLoop
- tapirl 11y ago
  yes, as @fao_ says, the Flash is just for demo. If your browser can't play this demo for any reason, you can view the videos to get how this app works: http://www.tapirgames.com/blog/ifloop-tutorials http://www.tapirgames.com/blog/ifloop-tutorials If there are really many people like this app, I will port it to HTML5.
  - fit2rule 11y ago
    Great stuff .. looking forward to seeing it running in HTML5.
highCs 11y ago
I like it. Example of what's cool: Syntax is just a theme You program can look like a python program, a golang program, or any other ones. Each code line can end with ; or not, etc. Is there program samples somewhere? Is there any lib for it?
- tapirl 11y ago
  Ah, currently, there is only the one default theme. I will add others in coming versions. There is no lib for it. This implementation is very simple. Contrary to text programming languages, which convert texts to object file, IfLoop converts object file to texts. A theme is just to define how texts are produced from the object file. Converting from obj file to texts is much easier than converting texts to obj file.
antender 11y ago
This app feels quite useless, because we already have TouchDevelop from MS.
- tapirl 11y ago
  You know, one of the reason why I made IfLoop is the experience of TouchDevelop is not good. There are still too many typing in it.
  - g8gggu89 11y ago
    There's way too much touching/clicking here, from what I see. This looks painfully slow.

  With that attitude we would still live in the stone age.

Something that requires me to install the flash plugin on 2015? Pass.
- tapirl 11y ago
  The reason I use Flash is to save development cost. Adobe AIR can help me distribute this app to web, pc/mac and mobile devices. I know HTML also works for these devices, but I am not familiar with HTML5. If there are many people like this app, I will try to port it to HTML5.
  - SchizoDuckie 11y ago
    If you want to launch anything in 2015 it's HTML5 or bust. If you know ActionScript, you know Javascript. Instead of Adobe Air, use something like nw.io / node-webkit, or Github's awesome Atom Shell.
    - et1337 11y ago
      Throwing in my two cents: Atom Shell is now known as Electron[1]. Clever, eh? [1] http://electron.atom.io/ http://electron.atom.io/
- madez 11y ago
  It's the same for me. It need's flash? No HTML version? I'm not interested...
bonobo3000 11y ago
This is a joke right?
- tapirl 11y ago
  Why?
actsasbuffoon 11y ago
It's an interesting idea, but it's hampered by a few things. First, you can only use variables or direct values as conditions, or as arguments to functions, etc. That's a severe restriction, and it feels time consuming to keep creating local variables to put those values into before-hand. Speaking of which, it would be nice if you could tap on an if-expression condition, and create a new local variable from inside that screen. It would save several clicks to get to the local variables screen.
- tapirl 11y ago
  thanks for your comment. like it very much. Yes, there are advantages, and also some disadvantages and restrictions, comparing to text coding style. Your suggestion is very great and workable I think. It is just v1.0 now. The improvement space is still very large. In coming versions, it will support drag-and-drop, drag to move items, etc.
singold 11y ago
This is really cool! Recently I've felt we need to advance in our programming tools, and this feels like a good step in that direction.
- tapirl 11y ago
  Ah, I really expect this coding style will occupy some space of the text coding style. But I don't know if it is an advance or not, :)
- nmrm2 11y ago
  I got about two minutes into the fibonacci tutorial before I couldn't stand watching any more. If you don't mind my asking, why do you feel this is an advancement?

If you're interested in coding interfaces on mobile, I've yet to see an on-mobile coding app as slick as Lisping[1]. Touch C[2] on WP8 showed potential, but sadly seems to be all but abandoned.

This is pretty neat! I didn't test it personally because flash / chrome but from the video I'd strongly recommend changing the selection animations / dialogs; at the cost of a bit more jarring UI I'd much rather have instantaneously available selections to choose so that I'm not bound by sliding windows, etc.
- tapirl 11y ago
  Thanks for the suggestion. Yes, part of UI will change much later.

Interesting concept. Point 3 here is however really worrisome. > Your IfLoop programs are always runnable, at any time. IfLoop programs even has no runtime errors. If you get a property of a null object or get an array element with an index out of range, a null value will be returned. If you use the null value as a Number, it will be viewed as 0. If you use the null value as a Boolean, it will be viewed as false. If you use the null value as a String, it will be viewed as a blank string. That is not good. Programs will just show unexpected behaviour. This is exactly what is terrible in PHP-land. You should not autocast values to other types. http://www.tapirgames.com/blog/ifloop-programming-language http://www.tapirgames.com/blog/ifloop-programming-language

Nice description, ACPUL is made for same purposes. 1. IfLoop has no compilers ACPUL also compile on fly + Live coding 2. IfLoop has no keywords ACPUL is no keywords & fully native translatable language 5.Every custom function can be used as the entry function Same, like JS. No-args functions. Also, ACPUL made for full UI customization, developer can made & run self-IDE. Here is easy sample, how I made new touch-input control for graphics, that much better than code editing like Codea, Mobile-C or TouchDevelop, IfLoop. https://www.youtube.com/watch?v=jf2JWD7wQmo https://www.youtube.com/watch?v=jf2JWD7wQmo ACPU: The Matrix - is remote control extension for integration with Desktop OSes. Here is demo video: https://www.youtube.com/watch?v=A4EpL1P47jc https://www.youtube.com/watch?v=A4EpL1P47jc Another sample is working version of DOTA-like game prototype with Physics, Networking & Graphics in some lines of code: https://github.com/d08ble/acpul-demo/tree/master/dota https://github.com/d08ble/acpul-demo/tree/master/dota I think, mobile developing is the Future, I'm very happy, than more & more peoples going in dev @ mobile. http://acpul.tumblr.com/ http://acpul.tumblr.com/
