Introduction

Hi there! This is quite a big release. It comes with imgui v1.92.3 :tada: as well as imgui impl wrapper (making it possible to implement more backends on go side).

Breaking changes

Some time ago, Dear ImGui came up with a big release - v1.92.0. This release contains several refactors such as:

• Fonts rework
• New TextureRef mechanism

This unfortunately caused several breaking changes in our project:

• The following obsolate, manually-wrapped functions have been removed:
  • TextureDataAsAlpha8
  • GetTextureDataAsRGBA32
• backend.Texture type was updated to use newly added imgui.TextureRef as its ID value.

[!tip]

• imgui.NewTextureRefTextureID is a function that could be used to convert imgui.TextureID to imgui.TextureRef.
• ref.TexID() returns imgui.TextureID.

Regular changes recap

• Added Go wrappers for imgui_impl_XXX files.
  • they are extremely useful when creating custom backends, e.g. it should be possible now to create a backend using go-gl/glfw (not tested yet)
  • At the moment, the following impl wrappers are available:
    • glfw (imgui_impl_glfw.h)
    • opengl3 (imgui_impl_opengl3.h)
    • sdl2 (imgui_impl_sdl2.h)
  • read more in a dedicated readme file: https://github.com/AllenDang/cimgui-go/tree/main/impl
• some missing ebitenbackend features have been implemented
• utils: there is a new helper method called PtrToSlice. Feel free to use it whenever you see fit :sile:.
