JarCastingOwlet
Owlet is a Typed Spreadsheet UI library for ScalaJS. It is built on top of Monix and Typelevel Cats to combine predefined input fields to a reactive user interface, just like what you would done in spreadsheet. Owlet is inspired by the PureScript library Flare.
Do one thing and do it well micro birds library series
Get Started
1. add dependency in your build.sbt
Stable
libraryDependencies += "us.oyanglul" %%% "owlet" % "<maven version>"
RC
resolvers += "jitpack" at "https://jitpack.io"
libraryDependencies += "com.github.jcouyang" % "owlet" % "<jitpact version>"
2. Now programming UI is just like using spreadsheet
import us.oyanglul.owlet._
import DOM._
val a1 = number("a1", 1)
val a2 = number("a2", 2)
val a3 = number("a3", 3)
val sum = fx[List, Double, Double](_.sum, List(a1, a2, a3))
render(a1 &> a2 &> a3 &> sum, "#app")
or
val a1 = number("a1", 1)
val a2 = number("a2", 2)
val a3 = number("a3", 3)
val sum = a1 |+| a2 |+| a3
renderOutput(sum, "#app")
eh... Ready for 3D spreadsheet programming?
You know spreadsheet is 2D, when we have monad, it became 3D
!!!Monad Warning!!!
val numOfItem = int("noi", 3)
val items = numOfItem
.flatMap(
no => (0 to no).toList.parTraverse(i => string("inner", i.toString))
)
- imagine that
numOfItemlives in dimension (x=1, y=1, z=0) - then
itemslive in dimension (x=1,y=1,z=1)
you can render either numOfItem or items seperatly, for they live in diffenrent z axis (which means render items you won't able to see numOfItem even it's flatMap from there
but you can some how connect the dots with magic &>
renderOutput(numOfItem &> items, "#output")
Anyway, just keep in mind that monad ops map ap flatMap... will lift your z axis parMap parAp parXXX instead, will keep them in the same z axis
