My laptop SSD seem to have died and is not recognized by the BIOS. Its under warranty but figuring out what I’ve done since last backup and which isn’t on the cloud is not going to be a fun experience.

As suggested by

I could technically use a capturing lambda + some ifdef emscripten to preserve some of the "easy-to-hack" benefits of using a single function... But the last thing I want in my samples is to make them more complex looking, so I wouldn't do that.

I was probably stubborn wanting all examples to follow the same layout, whereas technically only a few will work with Emscripten (the GL and WGPU ones).

To make it easier to build & maintain samples for Emscripten which *requires* a function to call on every frame, I caved in and refactored all examples so the main loop calls a function... github.com/ocornut/imgui/ I'm sort of already regretting the loss of elegance ...

Examples: refactor all examples with a MainLoopStep() function, to fa… · ocornut/imgui@96ab68e

…cilitate use with Emscripten. (#2492, #3699) Aligned all examples.

I've always been happy and rather protective of the fact that a vast majority of Dear ImGui examples apps had their main-loop entirely inside the main() function, it conveyed a certain elegance... 1/

The workaround for fix is to use Emscripten's C++ API to access raw data and bypass the GLFW emulation code (which could be fixed separately). (Thanks

@wolfpld

@FlohOfWoe

and Cody for guiding me through this - tho I am perhaps celebrating too early...)

After some misdirected shots in the dark, the bottom-line of this is that Emscripten emulates GLFW with JS code which has a small bug quantizing small values: github.com/emscripten-cor SDL emulation has the same issue but SDL nowadays uses Emscripten's raw API and isn't affected.

Unglamourously spent time recording mouse wheel events to fix/standardize scroll direction across all backends (involve small oddities w/ smooth scroll, natural/flipped dir, OSX axis-swap on Shift, SDL/GLFW customs, fun drivers, etc. Emscripten still not figured out properly).

Nothing complex (and the Emscripten oddities someone will probably figure out correctly soon) but given the amount of cases at hand I thought I would lay it down in a spreadsheet so I can stare at the data and each individual fix/workarounds.

Lifted limit of columns in a Table: previously limited to 64 as we used a 64-bits integer for various masks. It's now using dynamically resized bit arrays. Not a difficult change, but wanted to avoid the +20% cost the best PR occurred in Debug builds. Perfs are now same-ish.

The Dear ImGui Test Suite recently introduced ways to more formally add perf/stress tests (with a viewer written by

@rokups

). It is still under-utilized and in infancy but hopefully can lead us toward a culture where it's easier for contributors to be mindful of performances.

Bypassers rarely realize it when working on features, but the difference between code that takes 0.3 ms to perform xx and code that takes 0.03 ms makes a PR hit or miss. As a result most PRs fixing non-trivial stuff have enough perf issues they are not viable to merge.

Uh-oh. Been symbolically trying to keep open issues under 700 for a while but I just lost that battle today :shrug:

Recently I started working on Box2D 3.0 Goals: - converting main library to C - multithreading & performance improvements - capsules - eliminate polygon radius I'll be giving development updates on another site.

We are looking for any info/data about the Sega 8-bit version of "The Godfather" by Creative Materials / US Gold. It was near-finished in 1992-1993 but went unreleased. Do you know anyone near that dev team? One video clip aired in Netherlands in January 1993. RT appreciated!

FYI we uncovered 140+ protos on smspower.org so far but there are still handful of unreleased Sega 8-bit titles we haven't found: e.g. The Godfather, Robin Hood, Cube Zone, Die Hard II, Bubsy II, Moonball, Viking Child, We're Back, Buggy Dash, etc. Any info welcome!

1993 was a good year. Thanks to a combination of being a teenager with lots of free time and ahem, piracy, I’ve played all but two games in that list.

Those single-developer programming tools like Live++ (liveplusplus.tech), RemedyBg (remedybg.itch.io/remedybg), WhiteBox (whitebox.systems) are giving me hope we’ll eventually get to a point where hooking into a debugger or compiler will be easy to take advantage of.

Rendering Bidirectional Text with multiple fonts and styles in an immediate mode GUI

I shared in the past my WIP on rendering bidi/complex-script text in IMGUI. I'm releasing a writeup on the topic as well as the code in its wip/experimental state, just for reference.

hasen.substack.com

The sorely missing out-of-the-box feature in all IMGUI libraries

Fun fact, the change-log between v1.80 and v1.89 is ~1200 lines long. Between v1.60 and 1.89: ~3000 lines. That's to say, even though I am shy with version numbering increase, there are stuff happening. I wonder if more frequent releases would attract more updaters?

I'm sort of high on releasing stuff this week so adding Dear ImGui 1.89.1 to the list: github.com/ocornut/imgui/ + mentioning Test Engine/Test Suite + Dear Bindings in the GitHub release note is a way to gently increase their soft-launch visibility.

Please note the Test Suite is MIT licensed but Test Engine Library is custom open-source license (TL;DR; free for individuals, open-source, education and small companies; paid for large companies). Income aimed at sustaining main Dear ImGui work which stays and will stay MIT.

Been working on this on the side since 2018, used it to test Dear ImGui itself & catch regressions.

@rokups

and I added many tests over time. Opening it for people to add tests to their own app/tools. If you can control e.g. your game/engine via tools, you can now automate them.
