Dear ImGui Bundle documentation

Closing words

Who is this project for

As mentioned in the intro,

Dear ImGui Bundle is a comprehensive bundle for Dear ImGui, featuring various powerful libraries from its ecosystem. Designed to facilitate the creation of applications in C++ and Python across Windows, macOS, Linux, iOS, Android, and emscripten (Web apps), it is ideal for application developers, and researchers eager to dive into GUI development with ease and efficiency. This bundle simplifies the process, allowing you to focus on the creative aspects of your projects.

Dear ImGui Bundle aims to make applications prototyping fast and easy, in a multiplatform / multi-tooling context. The intent is to reduce the time between an idea and a first GUI prototype down to almost zero.

It is well adapted for

developers and researchers who want to switch easily between and research and development environment by facilitating the port of research artifacts
beginners and developers who want to quickly develop an application without learning a GUI framework

Who is this project not for

You should prefer a more complete framework (such as Qt for example) if your intent is to build a fully fledged application, with support for internationalization, advanced styling, etc.

Also, the library makes no guarantee of ABI stability, and its API is opened to slight adaptations and breaking changes if they are found to make the overall usage better and/or safer.

Acknowledgments

Dear ImGui Bundle would not be possible without the work of the authors of "Dear ImGui", and especially Omar Cornut.

It also includes a lot of other projects, and I’d like to thank their authors for their awesome work!

A particular mention for Evan Pezent (author of ImPlot), Cédric Guillemet (author of ImGuizmo), Balázs Jákó (author of ImGuiColorTextEdit), and Michał Cichoń (author of imgui-node-editor), and Dmitry Mekhontsev (author of imgui-md), Andy Borrel (author of imgui-tex-inspect, another image debugging tool, which I discovered long after having developed immvision).

This doc was built using Asciidoc.

Immvision was inspired by The Image Debugger, by Bill Baxter.

Alternatives

pyimgui provides battle-tested comprehensive python bindings for ImGui. I worked with this project a lot, and contributed a bit to it. In the end, I had to develop a separate project, in order to be able to add auto-generated and auto-documented python modules.

Dear PyGui (repository) provides python bindings for ImGui with a lot of addons, and a more pythonesque API, which makes it perhaps more suited for Python only projects.

About the author

Dear ImGui Bundle is developed by Pascal Thomet. I am reachable on my Github page. I sometimes blog. There is a playlist related to ImGui Bundle on YouTube.

I have a past in computer vision, and a lot of experience in the trenches between development and research teams; and I found ImGui to be a nice way to reduce the delay between a research prototype and its use in production code.

I also have an inclination for self documenting code, and the doc you are reading was a way to explore new ways to document projects.

How is Dear ImGui Bundle developed

The development of the initial version of Dear ImGui Bundle took about one year at full time.

The bindings are auto-generated thanks to an advanced parser, so that they are easy to keep up to date.

Please be tolerant if you find issues! Dear ImGui Bundle is developed for free, under a very permissive license, by one main author (and most of its API comes from external libraries).

If you need consulting about this library or about the bindings generator in the context of a commercial project, please contact me by email.

Contributions are welcome!

History

Three of my past projects gave me the idea to develop this library.

ImGui Manual, an interactive manual for Dear ImGui, which I developed in June 2020
implot demo which I developed in 2020.
imgui_datascience, a python package I developed in 2018 for image analysis and debugging. Its successor is immvision.

Developments for Dear ImGui Bundle and its related automatic binding generator began in january 2022.
