Announcing 'Dear ImGui Test Engine' + 'Dear ImGui Test Suite', available now. - automation/testing for Dear ImGui apps - run in your live app or headless on CI; - run at robot speed or simulated human speed; - export screens/videos for e.g. generating docs github.com/ocornut/imgui_tes…

Rarely does @ocornut speak publicly, but when he does, man, you learn a ton! Omar - author of Dear ImGui: spectacularly famous, easy to use, immediate mode UI library - has joined me to discuss his experience and library internals! We talk about the value of stable API, of principles behind Dear ImGui, how & when did he encounter the immediate mode for the first time - all of it with a sweet French accent! @ocornut thanks a lot for joining me! I had a great time!

That said after that recording I realized there were lots of things I kinda want to talk about, but it may work better if I am not left rambling around my own answers. The "10 years of dear imgui" posts took me long to organize but have interesting stuff:

Not betting on it but I hope there's something useful to someone in there... (I am not socially shy but I have little confidence in my ability of organize my thoughts while speaking, even more so in technical fields, so I generally tend avoid it!)

Funding: if your mid/large business uses Dear ImGui - and maybe you are approaching end of year budget/planning - please consider reaching out (PM/email) so I can help you help Dear ImGui !

What I meant is that apps now force you to update much more frequently in order to keep working.

The ios app landscape e.g. 5 years ago seemed much more resilient to apps being rarely or infrequently updated than today.

Ended up pushing this: (It's merely two heuristics so I might tell if a user making a bug report has asserts disabled. Not exposing full stringified version because it often contains absolute __FILE__ path, nor full length to reduce noise.) github.com/ocornut/imgui/com…

Ah. Just occurred to me that I could simply call MACRO(n++, true) and compare value for n...

My use case is that I want to maximize chances that a new user making a bug report will include in their pasted config/build info the fact that they are compiling with assert disabled, so I can adjust my feedback and report analysis accordingly.

- Could take address of successive functions to measure their size, e.g. empty1(), withasserts(), empty2() hoping for alignment to not interfere? - GCC apparently has an extension to take address of a label (&&label2 - &&label1), untested. Other ideas?

C/C++: Looking for suggestion for a way to sensibly detect if an assert macro was defined to emit no code (e.g `#define IM_ASSERT(_EXPR) (void)0`) in order to report it in my config/build info blob. In a portable way. It doesn't need to be perfect, only generally reliable...

- Spends 10 minutes investigating a weird highlighting issue. - Realizes that there's a pile of stuff sitting over the rarely used game controller stashed somewhere in a drawer, but connected. A button was held pressed.

Bit far-fetched, but I created a topic to gather links/videos of software using the Dear ImGui Test Engine for automation: github.com/ocornut/imgui_tes… If you happen to use this somewhere would be nice to drop a word of a capture! (pictured in video: Wonderland Engine / @WebXREngine)

Another beautiful way to represent data in #imgui in my game engine. It’s very helpful to be able to visualize low level rendering data like this. Thanks for this amazing library @ocornut This was built with ImGui and ImPlot Repo below. github.com/MrDrElliot/Lumina…

I wrote a blog post about fast call-stack backtracing. Hopefully, someone making an intrusive profiler, memory tracker, or logger will find it useful... bkaradzic.github.io/posts/fa…

Nothing screams more friendly and future-proof than webgpu.h having no define for a version number, nor any comments of that sort, and being unable to distinguish if it is a WGPU or Dawn header and implementation.

Emscripten users: are you generally/often up to date, or is your app/product occasionally stuck on older versions, for whichever reason?

Microsoft OneDrive is rolling out AI face recognition for your photos. But you can turn it off, right? Well, you CAN, but only “three times a year,” and Microsoft hasn’t clarified what that actually means. To disable (for now), go to Privacy & Permissions → People section.
