It doesn’t on my PC.

I’ve copy-pasted C enum from your example, when I type FPG<Ctrl+Space> there’s no way to auto-complete just the FPGAPARAM_ part, to be able to then press F to get FPGAPARAM_FOO. Using VC2017 here, with latest Visual Assist.

Which C++ IDE are you using?

Did it more than once.

Here’s one open source project where I’ve replaced most parts of the C++ standard library with EASTL: https://github.com/Const-me/vis_avs_dx

Here’s my header-only C++ library which allows users to switch between 16-bytes/32-bytes wide SIMD by using different C++ namespace, either Intrinsics::Sse or Intrinsics::Avx: https://github.com/Const-me/IntelIntrinsics/

I use VS at work, and I'm very happy with its code completions (except that the auto-popup behaviour is so unreliable or at least unintuitive. I'm sure there is an option to turn that off). I'm not aware of a way to complete to the largest prefix that is common to all completions, although something like that would be rather easy implement, too.
