Install with the Julia package manager.
import Pkg; Pkg.add("Alexya")
julia> ] add Alexya
How to use
First, load the package:
Then, we initialize
Alexya calling the
init("My application", 800, 600)
@init "My application" 800 600
init function and the
@init macro accepts 3 arguments: the
title of the window and the
height of the canvas, respectively. You can omit the
height, the default value for each is
Then, define your
@use function setup() # This function is called when # the app is starting println("Starting...") end @use function update() # this function is called every frame # draw something here using Luxor's functions end
Then, start the application by calling:
If you want to know how to draw things on the screen, check out the Luxor.jl documentation here.
# Example adapted from Daniel Shiffman - The Coding Train # https://youtu.be/0jjeOYMjmDU?list=PLRqwX-V7Uu6ZiZxtDDRCi6uhfTH4FilpH using Alexya @init "Fractal Tree" 800 600 # create a Canvas @layout aside(:v, 200) slider = @create Slider(0:π/12:2π; init=π/4, @margin(20)) φ = π/4 @use function update() global φ = value(slider) background("#515151") origin((@width)/2, @height) sethue("white") branch(150) end function branch(len) line(O, Point(0, -len), :stroke) translate(0, -len) if len > 4 gsave() rotate(φ) branch(.67len) grestore() gsave() rotate(-φ) branch(.67len) grestore() end end start()

About this package
English is not my native language, so if you see any errors, i'm sorry.
For what i can use this package?
Why do you have created this package?
I'm think julia is a perfect language for creating visualizations because of its performance and syntax, and i was trying to created a drawing package for that, but a find Luxor.jl and Gtk.jl so i decided to bring then together.
What performance benefits i'll have?
I guess you'll have good performance if you don't try to draw something real crazy, like more than 1 thousand little things that constantly updates on the screen, for that, i'll recommend to you learning other packages that use OpenGL or learn how to draw with OpenGL from scratch, but this package is good if you want to relax and create simple visualizations that the user can interact with, you can even create the Snake game.
Well... I think there is a package that allows you to create 3D things with Luxor, but, if you really want to draw 3D things, i don't think this is the better package for you to use. Like i said above, try messing with OpenGL. But, in the future i'll try to implement 3D with OpenGL in this package, but not for now.
How can i contribute?
I'm not a professional developer, programming is my hobby, and most of my projects came from that (even what i study on college doesn't have anything to do with programming), but i love to code, and if you see some bugs or things that you can optimize, feel free to creating a issue or pull request.
Why the name?
Well, Alexya is a friend of mine, and just think her name is so beautiful, and also i'm terrible at choosing names, so i just picked her name.
