Canot ressolve intellisense with namespace alias.

[Alfi Maulana (threeal)]

say i have the following code on the header.

namespace something
{

class  SomeClass;

void some_function();

...

}

And then i include it in another files, write something:: and then tab, tab, then it lists contents of the something namespace. but when i alias it like this:

namespace smt = something;

When i write smt:: and then tab, tab, it doesn't list contents of the something namespace. So how could i fix it? or does this feature hasn't been added yet?

I don't repro the issue on Windows or Linux. Can you provide more info?

[Alfi Maulana (threeal)]

It shows the following logs

Version: 1.5.0-insiders2
Current Configuration:
{
    "name": "Linux",
    "includePath": [
        "${workspaceFolder}/**"
    ],
    "defines": [],
    "compilerPath": "/usr/bin/gcc",
    "cStandard": "gnu17",
    "cppStandard": "gnu++14",
    "intelliSenseMode": "linux-gcc-x64",
    "compilerArgs": [],
    "intelliSenseModeIsExplicit": false,
    "cStandardIsExplicit": false,
    "cppStandardIsExplicit": false,
    "compilerPathIsExplicit": true,
    "browse": {
        "path": [
            "${workspaceFolder}/**"
        ],
        "limitSymbolsToIncludedHeaders": true
    }
}
No active translation units.

Is there something wrong with my configuration that caused it to output "No active translation units"?
I also already enabled debug log, and it outputs the following lines:

I don't see any didOpen event in your logging. What does the logging show after opening a C or C++ file?

[Alfi Maulana (threeal)]

this is when i open vscode, close the file, and reopen it, i also check autocomplete of smt::, and then something::, and then smt:: again

Your C_Cpp.intelliSenseEngine is set to "Tag Parser". You need to change that to "Default" in order to get the desired behavior ("Tag Parser" mode has limited functionality).

IntelliSense Engine = Tag Parser. is shown in your logging.

[Alfi Maulana (threeal)]

nice, thanks for the answer
