Javis v0.2 and the Future
opensourc.esThis is a misleading title, it looks more like a “what’s new” changelog than... “Build easy animations with Julia”. It even talks about tutorials they will write, in the future.
It’s actual title “Javis v0.2 and the Future” seems to more accurately describe its contents.
Ok, we've changed the title from "Build easy animations with Julia". Thanks!

Thanks for the comment. I struggled with giving it a title that fits and still shows outsiders what the package does. Now nobody knows what Javis is and maybe thinks it manipulates the future On my blog I attracted more the people who are already familiar with Julia and Javis.
It looks like a good package, and wasn't trying to put it down in any way it's just this... isn't at all what I expected from the title, and IMO the content doesn't seem to be immediately enlightening for people who don't already what it is.
To be honest, the main github repository root, as it appears to me, does a better job of showing off the package and explaining what it is. "Javis: Julia Animations and Visualizations" with that link would be both clear and interesting (to me - opinions may vary!).
Whereas the blog post is exactly what I'd expect from it's actual title - "Javis 0.2 and the future" - discussing new changes and plans for future features.
For someone who's been following this only tangentially, how similar is the interface and implementation to what's used in Grant's https://github.com/3b1b/manim ?
So, to give an example:
In manim, one could do something like this:
To have a square morph to a circle. Currently in Javis, one could do something like this:from manimlib.imports import * class ReplacementTransformExhibit(Scene): def construct(self): square = Square().shift(LEFT) circle = Circle().shift(RIGHT) self.play(ReplacementTransform(square, circle))
As you can see, Javis is, at this stage, a little more verbose. However, for v0.3.0 we are moving away from Action syntax to something more generic and user friendly (this shift based on user feedback).using Javis astar(args...) = star(O, 50) acirc(args...) = circle(Point(100,100), 50) function ground(args...) background("white") sethue("black") end video = Video(500, 500) javis(video, [ Action(1:100, ground), Action(1:50, morph(astar, acirc)), Action(51:100, morph(acirc, astar)) ], creategif=true, tempdirectory="images", pathname="star2circle.gif", deletetemp=true)
this would be an excellent suite of animations to try to develop: https://en.wikipedia.org/wiki/User:LucasVB/Gallery
i started trying to build up a racket animation library to reproduce that gallery, but i didn't get very far.
Hey zem,
Our goal is to rather become a generic package people can use to make whatever animation or visualization in whichever domain they see fit. We are slowly building out our own showcase of animations based on tutorials we provide the user (see link here for tutorials: https://wikunia.github.io/Javis.jl/stable/tutorials/)
We are also currently seeking contributions to our examples section here: https://wikunia.github.io/Javis.jl/stable/examples/ If you want to contribute, happy to support!
my point was that would make a great set of use cases for what functionality your library needs. it's hard to develop a generic package that anticipates what needs are common.
