alt Hacker NewsInteresting read, however as someone from the same age group as Casey Muratori, this does not make much sense.
> The "immediate mode" GUI was conceived by Casey Muratori in a talk over 20 years ago.
Maybe he might have made it known to people not old enough to have lived through the old days, however this is how we used to program GUIs in 8 and 16 bit home computers, and has always been a thing in game consoles.

It's like the common claim that data-oriented programming came out of game development. It's ahistorical, but a common belief. People can't see past their heroes (Casey Muratori, Jonathon Blow) or the past decade or two of work.
There's also good reasons that immediate mode GUIs are largely only ever used by games, they are absolutely terrible for regular UI needs. Since Rust gaming is still largely non-existent, it's hardly surprising that things like 'egui' are similarly struggling. That doesn't (or shouldn't) be any reflection on whether or not Rust GUIs as a whole are struggling.
Unless the Rust ecosystem made the easily predicted terrible choice of rallying behind immediate mode GUIs for generic UIs...
I mean, fair enough, but [at least] wikipedia agrees with that take.
> Graphical user interfaces traditionally use retained mode-style API design,[2][5] but immediate mode GUIs instead use an immediate mode-style API design, in which user code directly specifies the GUI elements to draw in the user input loop. For example, rather than having a CreateButton() function that a user would call once to instantiate a button, an immediate-mode GUI API may have a DoButton() function which should be called whenever the button should be on screen.[6][5] The technique was developed by Casey Muratori in 2002.[6][5] Prominent implementations include Omar Cornut's Dear ImGui[7] in C++, Nic Barker's Clay[8][9] in C and Micha Mettke's Nuklear[10] in C.

[Edit: I'll add an update to the post to note that Casey Muratori simply “coined the term” but that it predates his video.]
> Maybe he might have made it known to people
Yes, he coined the term rather than invent the technique
I think this is the source of the confusion:
> To describe it, I coined the term “Single-path Immediate Mode Graphical User Interface,” borrowing the “immediate mode” term from graphics programming to illustrate the difference in API design from traditional GUI toolkits.

Obviously it’s ludicrous to attribute “immediate mode” to him. As you say, it’s literally decades older than that. But it seems like he used immediate mode to build a GUI library and now everybody seems to think he invented immediate mode?
