Before I comment, I'll just express how insanely cool this is. Mobile programming environments suck right now and this is a step in the right direction. Good proof of concept.<p>Excuse me if this is implemented and just not in the README:<p>It would be super awesome if there was a type inference engine that fed into the UI to increase productivity.<p>For example, if I start to define a function that returns an int, when I go to write out the definition, it suggests functions to me that return ints.<p>Suppose I pick a function "string_length" which takes strings and returns ints. Now I continue the composition, so it suggests functions (either built-ins or user-defined) which return strings.<p>Suppose I pick "bool_to_string" which takes a bool and returns strings. Then to finish off the function I pick from a list of bool-returning functions, say I pick "xor".<p>So now with a few keypresses I have defined a function that, in C, would look like:<p><pre><code> int foo(bool x, bool y) {
return string_length(bool_to_string(x ^ y));
}</code></pre>
My first thought was, "How does this compare to Swift?" But this is totally different: you want to create useful programs _on_ the touchscreen device.<p>It's purely functional and stack-based. This is a clever approach to the UI problem - how to program when you can't typeLongWords? Answer: use the stack! I expect the act of writing programs will feel a lot like using an old programmable calculator.<p>Really excited to see how this progresses!<p>PS: How do I run that demo locally?
1. Holy shit that is a fantastic way to do mobile UX. Radials for each thumb? Fucking brilliant. I could imagine this could also make a great keyboard layout for certain domains<p>2. I would flip out even more if this UI was available for more mainstream functional languages like Haskell or Clojure. Do libraries break the process? I don't think they have to.
Nice work! I have been playing around with touch programming concepts for a while but did not yet dare to show any to the world. Let this stimulate me in that and hope others will follow. Even if just for fun.
