ImGuin

Latest ImGui/CImGui version: : v1.90.4dock

Notice:
This project is my experiment project to use Nim language, ImGui, ImPlot, futhark and etc.
It may be better to use the mainstream project nimgl/imgui (ImGui v1.85)
,updated project nimgl-imgui (ImGui v1.89.9) ,sub project nim_implot and test project nimgl_test.

Usage: Sample program and run

Prerequisites

• Nim-2.0.2 or later (Windows10 or Debian Linux)

• For Linux Debian 12 Bookworm,

  $ sudo apt install xorg-dev libopengl-dev libgl1-mesa-dev
  

  and for glfw3 and sdl2,

  $ sudo apt install libglfw3 libglfw3-dev
  $ sudo apt install libsdl2-dev
  

Install

nimble install https://github.com/dinau/imguin

Build examples

1. First clone this project,

   git clone --recursive https://github.com/dinau/imguin
   

2. Sample program is here, examples. For instance glfw_opengl3.nim,

   cd imguin/examples/glfw_opengl3
   make
   

   After build, run ./glfw_opengl3(.exe)

3. For selecting static link or dynamic link ,read this examples/README.md.

Screen shot (examples)

These screen shots are on Windows10.

Update to latest Dear ImGui and CImGui

Prerequisite

1. Git installed.

2. Windows10 or later Clang/LLVM refer to Futhark installation.

   nimble install --passL:"-Lc:\llvm\lib" futhark
   

   It must exist libclang.a file in the library path (e.g. "c:\llvm\lib").

3. Linux Debian 12 Bookworm

   sudo apt install  clang-16
   nimble install --passL:"-L/usr/lib/llvm-16/lib" futhark
   

Important Notice: Confirm Futhark version is v0.12.5 at this time. (2024/03)

nimble dump futhark

name: "futhark"
version: "0.12.5"
author: "PMunch"
desc: "A package which uses libclang to parse C headers into Nim files for easy interop"
license: "MIT"
...

Update ImGui/CImGui

• Update to latest definition files uisng Futhark,

  pwd
  imguin
  cd src/imguin/private/updater
  make
  

• Update/Downgrade to the version specified tag for example,

  pwd
  updater
  make VER=1.89.9dock
  or
  make CIMGUI=1.89.9dock
  

• Confirmed version

  Command	imguin Ver.	Date	Windows10	Debian Bookworm
  make VER=1.90.4dock	1.90.4.2	2024/02	ok	ok Notice(1)
  make VER=1.90.1dock	1.90.1.0	2024/01	ok	NG Notice(2)
  make VER=1.89.9dock	1.89.9.8	2023/12	ok	NG

  Notice(1) : Except imnodes and SDL2 example. Notice(2) NG: Doesn't work well.

Examples notice

• examples/sdl2_opengl3

  1. If you are on Windows OS 32bit, you should get SDL2.dll for instance from release-2.26.4.

     1. Unzip SDL2-2.26.4-win32-x86.zip
     2. Copy SDL2.dll to examples/sdl2_opengl3 folder.

  2. On Windows OS, it needs dev tool to compile SDL2 app, SDL2-devel-2.26.4-mingw.zip for instance "SDL.h","-lSDL2.dll" etc and change src/imguin/sdl2_opengl.nim

     {.passC:"-Id:/msys32/mingw32/include/SDL2".}
     {.passL:"-Ld:/msys32/mingw32/lib -lSDL2.dll".}
     

     you need to properly change the above folder name depending on your settings. See src/imguin/sdl2_opengl.nim

TODO

1. Added: ImNodes/CImNodes (2023/10)
2. Easier compilation for SDL2 app.
3. Whether can it use cimgui.dll ? (Now it can only be static link)
4. ~~Unfortunately ImGui 1.89.7 dosn't work well at this moment.(2023/07)~~ Done. (2023/08)
5. ~~Whether can it do nimble install imguin ?~~ Done (2023/09) (#Issue 13)
6. ~~Add Font Awesome (Icon Font) demo.~~ Done (2023/04).
7. ~~Can it compile with MSVC (--cc:vcc) ?~~ Done. Except SDL2 demo. (2023/03)
8. ~~Can it compile with Clang (--cc:clang) ?~~ Done. (2023/03)
9. ~~Add SDL2 example.~~ Done. examples/sdl2_opengl3 (2023/03)

• First step is done. (2023/03)
