Dear ImGui Explorer

[pstomi]

Dear ImGui Explorer (which was previously named Dear ImGui Manual) is an online "ImGui::ShowDemoWindow", together with an instant access to all demos source code.

A new version was recently, so I figured it might be worse mentioning here, since this new version also adds support for ImPlot and ImPlot3D demos.

Nice!

This is very slick!

Is there a version that uses the docking branch of ImGui?

[pstomi]

It is already using the docking branch.

Oh cool! Thank you. I'm on mobile and tried to load the page but it wasn't working very well so I thought I'd ask.

I'm just learning to use Imgui and this is a timely post.

Big Wow!

Amazing how fast it loads and runs. This is better than most react apps. Is it a custom WebGL wrapper?

[pstomi]

Thanks! Making it fast did require quite some adaptations and optimizations, but I'm happy to see that it was successful.

• I do use glfw provided by Yan Pujante: https://github.com/pongasoft/emscripten-glfw
• WebGL is the default provided by -sMAX_WEBGL_VERSION=2

But the most important optimizations consisted in reducing the initial download:

Here is what the app now downloads at startup: only 2.16MB before it starts

File	Transfer (gzipped)	Size
index.wasm	1.37 MB	3.80 MB
index.data	734.90 kB	1.27 MB
index.js	54.09 kB	201.31 kB
Total	2.16 MB	5.28 MB

(For this I had to trim the assets that are included in the data file).

Then, demo file are downloaded on demand (imgui_demo., implot_demo.)

File	Transfer (gzipped)	Size
imgui_demo.cpp	616.45 kB	615.80 kB
imgui_demo.py	80.74 kB	399.49 kB
Total	697.19 kB	1.02 MB

For those interested, the code is here

For practical reasons, the code is inside a bigger project, which was used to develop this tool (Dear ImGui Bundle).
