Use a modified JB

[tiawl]

Most of the time, JB is described as an anti-pattern. Getters and Setters kills the encapsulation by making private attributes public. In the case of a OOP language, this is something we have to think twice when considering JB. However, in the case of Zig, there no OOP and there are (and will be) no private attributes for structs.
With this state of the art in mind, we consider that using JB should improve maintainability.
Here the accepted proposal of a modified JB:

• A struct should have:
  • mandatory getters: NEVER use attributes outside of getters
  • prefixed attributes (with __): to make an easy distinction between attrbutes and methods: NEVER use attributes outside of getters and init ()
  • mandatory init: NEVER use a struct constructor outside of init function
  • immutable setters: NEVER mutate the value of an attribute (outside or inside the struct), ALWAYS build & return a new object from the struct

[TODOLIST] Make those changes in:

• main:
  • spaceporn
  • build.zig
  • compiler
• dependencies:
  • toolbox: [update] use modified JB toolbox#36
  • vulkan
  • wayland: [update] use modified JB wayland.zig#37
  • X11: [update] use modified JB X11.zig#31
  • glfw
  • cimgui: [update] use modified JB cimgui.zig#35
  • spirv: [update] use modified JB spirv.zig#28
  • glslang: [update] use modified JB glslang.zig#28
