Exclude System Included symbols/variables from autocomplete

[Richhoef]

Type: LanguageService

Is it possible to exclude the symbols/variables/etc which are found by the systemIncludePath from the auto complete?
I only want symbols/variables which are found in the files under the includePath and/or the browse.path to be suggested to me when I type. Now, the first things that are suggested are always many many variables which I have never used and probably will never use. Only when I type more characters, the list will become relevant.
I can get the desired behaviour by setting the C_Cpp.default.systemIncludePath to "C_Cpp.default.systemIncludePath": [""], (and not including those path's as includePath in the c_cpp_properties.json), but this has the, logical, (side) effect of intellisense not being able to find some of the files that are being included. If a variable found by the 'systemIncludePath' is used somewhere in the file, it obviously is being used and would be allowed to be suggested. This would make typing so much faster and nicer!

Reading customize default settings cpp #system-includes I thought the desired behaviour described above would already (supposed to) be the case, but I do not get it to work. Help is very much appreciated.

If more informating is needed, I would be happy to provide it!

Besides the above, it would also be nice to have variables that are used recently at/near the top of the list (depending on how often they are used recently). This would also speed up typing a lot.

Yeah, we'd have to add completion filtering based on the file path, possibly checking files.exclude or some other new setting.

This feels like too big of a hammer to solve the problem. I think that #1798/#4939 would address the root cause of the issue (too much info) and make the completion list more manageable. I wouldn't think that you'd really want to remove completions for all STL types (which is what I assume are the types of files pointed to by your systemIncludePath.

(And as an aside, if it is the standard C/C++ headers you're specifying in systemIncludePath, consider using compilerPath instead. You will get better IntelliSense.)

We'll close this as a duplicate of 1798 and 4939.
