           Summary: Parameter list helper doesn't appear(/exist?)

In Visual Studio, go into a .c/.cpp file:

Place the cursor within the parameter list of any function call and press
Ctrl+Shift-Space; notice that a helper appears detailing the expected
parameters.
Do this in the parameter list for a function that has multiple parameters;
notice that the parameter the cursor is currently positioned upon is
highlighted in BOLD. Move the cursor left/right using the arrow keys, and watch
the bold highlight follow the cursor.
Do this in a parameter list for a function with overloads; notice that the
helper now says "1 of N", and allows you to cycle through the overloads using
the up/down arrow keys.
Begin typing a new call to a function; notice that the helper appears when
typing the opening '('.
Begin instantiating a template; notice that the helper appears also for
template argument lists when typing the opening '<'.

VisualD doesn't seem to offer this very important helper.
It would be nice if D had the same parameter list helper as C/C++.

This feature is available in Visual D, but it builds on generated JSON information. That means, it does not know about the current context, so can be very wrong for commonly used function names. An additon, a successful build is necessary to display anything. (Use "Build Phobos browse information" for phobos/druntime parameter infos.)

As the JSON output has lost it usefulness for this functionality, I guess I'll have to look into getting this information from the semantic analyzer.

The very latest version uses dparser's output to generate the parameter toolti, try it in https://github.com/D-Programming-Language/visuald/releases/tag/v0.3.38rc2

I just gave it a whirl. Big improvement - regular functions are working properly now. But there are some things still not working:

Constructors don't seem to list args?
  auto doc = new Document(new Tag("settings"));
  auto devs = new Element("devices");
  testMat = Material("diffuse_uncompressed_gimp.dds");

None of these new statements offer any parameter info.


to! doesn't work:
  to!string(videoDriver)

This shows the helper for 'string's constructor, not 'to'.


Cheers for all your work! It's getting better all the time! :)
