Vcpkg VS imgui

5.4.5 can be compromised

https://github.com/microsoft/vcpkg/issues/37197

vcpkg may expire assets after 1.5 years, so achieve long-term reproducibility you will need to cache your dependencies.... Somewhere. Not sure what the expected solution is.

https://github.com/microsoft/vcpkg/pull/30546#issuecomment-1...

There were various approaches recommended depending on our language and ecosystem. My classmates who developed using Node.js were recommended npm, and PyPI or poetry for Python. Since my program is written in C++, I was recommended to look into one of vcpkg or conan, but I ultimately did not use either package manager.

Which dependencies are not in vcpkg? We can ask them to add it. It’s pretty easy just open an issue there https://github.com/microsoft/vcpkg/issues .

The hyperscan update to vcpkg seems to have happened from 5.4.0 to 5.4.2 in this commit on Apr 20.

Dear Fictrac team, I am hoping to install Fictrac in our windows 11 x64 laptop (Visual Studio 2019, cMake 3.26.4). I followed the installation guideline on github page fictrac and used the latest vcpkg

unless you want to use clang-cl since it renames the output to make it work for MSVC which in return breaks FindBoost in cmake and requieres https://github.com/microsoft/vcpkg/pull/27694 to fix it. I have touched enough of vcpkg build scripts to know what works and what doesn't and the b2 build is one of the corners I strongly dislike.

And then there's also Qt which has plugins. vcpkg Qt5 is nice enough to copy the plugins for you, but not with Qt6. The official answer seems to be "use windeployqt". So I do, and it copies plugins fine. But sqlite doesn't work, despite the plugin sqldrivers/qsqlite.dll being in the right location. Turns out that neither vcpkg or windeployqt copy sqlite3.dll. I switched to static libraries after that, it's a lot slower to link, clang doesn't work for some reason (but clang-cl does) but at least I don't have to worry about DLLs.

Immediate mode is a fuzzy concept, as witnessed by this writeup: https://github.com/ocornut/imgui/wiki/About-the-IMGUI-paradi...

The Dear ImGui readme is a good starting point:

https://github.com/ocornut/imgui

...now of course Dear ImGui is a specific implementation of an immediate mode UI framework, but it's also the most popular implementation.

From the faq https://github.com/ocornut/imgui/blob/master/docs/FAQ.md#q-w...

Q. What is this library called?

This library is called Dear ImGui. Please refer to it as Dear ImGui (not ImGui, not IMGUI).

(The library misleadingly started its life in 2014 as "ImGui" due to the fact that I didn't give it a proper name when I released 1.0, and had no particular expectation that it would take off. However, the term IMGUI (immediate-mode graphical user interface) was coined before and is being used in variety of other situations e.g. Unity uses it own implementation of the IMGUI paradigm. To reduce the ambiguity without affecting existing code bases, I have decided in December 2015 a fully qualified name "Dear ImGui" for this library.

ImGui is engine/GPU agnostic

Themeing isn't a just a retained mode thing, you can do wonders with immediate UIs, even thought (dear)ImGui doesn't provide much, you can still do wonders: https://github.com/ocornut/imgui/issues/707#issuecomment-362...

My first guess would be it is supposed to sound like "Dear Imogen". However, it wasn't initially conceived of as a reference to anything. The "Dear" was tacked on to qualify the name [1].

Bonus: If you want to make desktop app with UI, then this is another great C++ library and it's also simple to learn as well. https://github.com/ocornut/imgui.
