ImGuin

Updated to latest Dear ImGui / CImGui version: : v1.92.6 dock (2026/02)

This project is Dear ImGui wrapper library for Nim[^notice].

[^notice]: 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,
or https://github.com/daniel-j/nimgl-imgui (ImGui v1.91.1)

rlimgui_basic

Prerequisites

---

• Nim-2.2.8 or later

• Windows11 or later
  MSys2/MinGW command line tools (Unix tools), make, cp, rm, git, ...etc

  pacman -S mingw-w64-ucrt-x86_64-glfw make
  

• Linux: Ubuntu / Debian families

  $ sudo apt install gcc g++ make git curl xz-utils
  $ sudo apt install lib{opengl-dev,gl1-mesa-dev,glfw3-dev,xcursor-dev,xinerama-dev,xi-dev,sdl2-dev} 
  

  • Install nim

    curl https://nim-lang.org/choosenim/init.sh -sSf | sh
    

    You must now ensure that the Nimble bin dir is in your PATH. Place the following line in the ~/.profile or ~/.bashrc file. export PATH=/home/username/.nimble/bin:$PATH

Update / Downgrade Dear ImGui and CImGui by yourself

---

• Prerequisite

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

     nimble install futhark
     

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

  2. Linux Debian / Ubuntu families

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

  Important Notice: Confirm Futhark version is v0.15.0 at this time.

  nimble dump futhark
  

• Update / Downgrade ImGui/CImGui

  1. Compose development folders
     First move to your working folder you like, then

     mkdir imguin_dev
     cd imguin_dev
     git clone https://github.com/dinau/imguin
     cd imguin
     

  2. Clone ImGui/CImGui etc. sources at once forever

     pwd
     imguin
     make clonelibs
     

     Cloned libraries are under ../libs/ folder

  3. Recursively update the sources using git pull or fetch in the each library folder,
     ../libs/cimgui
     ../libs/cimguizmo
     ../libs/cimnodes
     ../libs/cimplot
     ... snip ...

  4. checkout arbitrary version with git command in the respective folder

  5. Specify your Clang include path to ClangIncludePath in imguin/src/imguin/cimgui.nim.

  6. Generate the definition file uisng Futhark,

     pwd
     imguin
     make gen
     

  7. Install updated files
     Properly edit the version info etc in imguin.nimble file, then

     pwd
     imguin
     nimble uninstall imguin  # Remove old versions if it exists. 
     nimble install 
     

     That's all.
     Repeat from 3. if you'd like to update or downgrade to other version.

• Confirmed version
  Windows OS is all OK.

  (1) Except imnodes and SDL2 example.
  (2) Works well only if it is compiled debug mode.
  (3) Dedian / Ubuntu familiy.
  (4) Doesn't check, but probably will work well.

TODO

---

1. ~~Whether can it use cimgui.dll ? (Now it can only be static link)~~ Closed. Only be static link.
2. ~~Easier compilation for SDL2 app~~. (2024/09) Done.
3. ~~Added: ImNodes/CImNodes~~ (2023/10) Done
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), TODO (2024/09)
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)
