ImPlot example with state-management and Renderer

Just rewrote the example from demo/example_plots.jl, using Renderer to hide ImGUI boilerplate code, as explained here.

However, there are some things I don't like in this example:

• store state variables inside a structure - it will be very bloated for complex GUI - is there some static macro in Julia, or isdefined for local variables?
• passing state with field destructuring - maybe it's fine to write state. in front of all data variables.

you may find this useful. I prefer Redux.jl for something scalable, but it needs even more boilerplate code.

@Gnimuc thanks for the links!
Using @cstatic has some limitations:

1. you cannot write complex initialization code that should be run only at startup,
2. it is just one-liners for variables, and if there are many variables, the code becomes messy:

using CImGui.CSyntax.CStatic
function foo()
    @cstatic a, b, c = 1, zeros(3), [x^2 for x in 1:5] begin
        a += 100
        b .+= 10
        c .+= 1
        println("$a,$b,$c")
    end
end
function loop()
    for i=1:10
        foo()
    end
end

loop()

I don't quite understand strong parts of Redux from the link above.

Can you point me to some complex ImGui projects and how do they actually handle state-sharing between a whole lot of GUI components in the scene, if they interact with each other?

Closing this. These are CStatic / ImGui questions.
