I've been meaning to add this for years but needed to
(1) find an optimal impl. This does zero search, adds two int32 == compare on visible/non-clipped items, pulling values from hot memory.
(2) avoid making the lib spammy. The last thing we want is to add booting up notifications to ignore for thousands of contents creators. Was careful with design and wording, but since this detects a programming error it should be fine. We'll find out.

Dear ImGui users: added 'io.ConfigDebugHighlightIdConflicts' debug tool to highlight conflicting identifiers.
Small, much requested tool. Now happily came up with an elegant and optimal implementation for it. Enabled it by default to battle test it! https://github.com/ocornut/imgui/wiki/Debug-Tools

@npub1a0p…6xz3 I have to say that I sort of like the explicit X11 name over a less explicit LEGACY one, but I imagine the whole purpose of this name is to discourage people from using it.

Am I the only person who quite dislike how websites nowadays are displaying dates in a relative and vague manner? (e.g. "2 weeks ago", "3 months ago") ?
I keep mouse hovering those just because my brain insists on seeing a raw date.

Made a few changes:
- amended section 6.9 about existing GUI/Layout editors. In particular, ImRAD (https://github.com/tpecholt/imrad) is noticeably more powerful, cater for data binding + hand-rolled C++ parser to allow iterations.
- mention accessibility a little bit better in section 5.

When I posted imgui 1.0, i didn’t have any plan nor expectation. For context, this type of IM API was unknown to many/most people back then. I will publish a blog post in a few days - I was hoping for it to be today, but I am not fast.

In 12 days I will address the nation regarding upcoming plans for dear imgui, general thoughts, and putting more energy on topics that no one cares about such as: fonts, dpi scaling, styling, docking.

@npub129t…mdn4 my personal theory about why so many indie games are failing is that makers don’t look at their potential audience enough. It all boils down to that.

2024-07-25 16:14:06

@npub1qfa…y6fn I suspect that there is a bit of that indeed.

2024-07-25 16:13:26

@npub129t…mdn4 Yes, it is essentially caring about your audience.

2024-07-25 15:32:04

Once in a while I watch a video of someone integrating the library, taking notes of how I could improve that experience.
It often comes down to people not spending 2 mins reading what's in front of them, so my job has been to plant redundant info in various locations.
Basically trying to increase the odds that they end up finding the information without wasting 30 minutes misdirected. Information redundancy has been useful.

It's not perfect e.g. no cross-context interleaved windows or docking, but does a decent job making that use case possible. So larger apps have the option to display multiple contexts simultaneously.
(this little extension was commissioned by Valve, thanks!)

2024-07-17 10:04:10

Released Dear ImGui Multi-Context Compositor: a helper to facilitate displaying & interacting with multiple contexts simultaneously (e.g. update vs render domains contexts): https://github.com/ocornut/imgui_club
Manages z-order, mouse/keyboard routing, cross-context drag and drop etc.

ImHex has an achievement tree !? I'm not sure how I feel about achievements popup showing in an hex editor (they are easy to disable) but it's actually an interesting way to engage users into discovering features!

@npub1qv5…k9w9 I don't off hand but you should scan the git and wiki for leads. Any library that can turn SVG into raw textured triangles could be piped into ImDrawList.

I know of various high-profile titles using dear imgui that are not disclosed, where I would find it fun to find a public proof, e.g. scan executables to find leftover strings or filenames.
In theory such scanner could be run on every console/steam executables if someone had access to them. Not exactly an important thing to pursue, but i occasionally considered it.

@npub1qnn…w7ad This is the context https://github.com/epezent/implot/issues/445 but I have also had requests for ImGui, e.g. consider an API like:
bool ImGui::Combo(const char* label, int* current_item+idx, const char* (*getter)(void* user_data, int idx), void* user_data, int items_count, ....);
