Like Eclipse? QT Designer? Code::blocks?
All I see is Visual Studio for Windows and Xcode for Mac.
I think at this point, GNOME Builder (https://git.gnome.org/browse/gnome-builder/tree/plugins/meson) only.. (but I'm not sure)
Yup, Builder support should be solid and eventually we plan on more advanced integration. If somebody wants to make plugins for other IDEs it is fairly easy: https://github.com/mesonbuild/meson/wiki/IDE-integration
I once asked of support for meson in jucipp IDE and they delivered it pretty quickly. So there's one more.
The reason why we have our own backends for XCode and Visual Studio is because it is extremely unlikely (almost impossible) that the upstream projects will add support for Meson. XCode lives in its own little garden and pretends nothing else exists, and we're not big enough for Visual Studio to care about us.
However, it makes much more sense for IDEs to add support for Meson in their own codebase because it allows for much better integration. Some projects are doing that, but it's not up to us what they do. :)
