Visual Studio Code Intellisense Mode

Question

What are valid values for the c_cpp_properties.json tag "intelliSenseMode" ?

It defaults to clang-x64, but I am compiling with g++ so is there another value I can use there? I can not find any documentation about it.

github.com/Microsoft/vscode-cpptools/blob/master/Documentation/… - specifies 2 possibilities "msvc-x64" / "clang-x64". Second is default for Linux env – Lesialesion

Huh I don't know what I googled wrong but that page did not appear in my first 10 results. – Sal

Answer 1

Because Artemy Vysotsky did not post his answer as an answer:

The documentation states that "msvc-x64" and "clang-x64" are the only possible values.

Sal

As of now it is also possible to choose gcc-x64. (supposedly the default value on Linux but my Linux vscode installation defaults to clang-x64) – Heraclid

This answer is out of date, many values are actually possible. See code.visualstudio.com/docs/cpp/… – Storage

Answer 2

When editing the .json configuration file, just type "intelliSenseMode": "" and let intelliSense itself help.

Actually you may use the option "intelliSenseMode": "${default}" to allow self selection.

I am getting this warning because of line number 16

Just change "intelliSenseMode": "windows-msvc-x64" to "intelliSenseMode": "windows-gcc-x64"

Answer 4

I was having the same problem, if you're using Windows

I used "g++.exe"

Then I changed the "IntelliSense mode" to "windows-gcc-x64" to get rid of the warning

Answer 5

Since v0.25, 32 bit modes are supported. The valid options are msvc-x64, gcc-x64, clang-x64 and their 32 bit counterparts msvc-x86, gcc-x86, clang-x86. There's also the ${default} option that Fábio Lobão mentions.

Answer 6

Hovering on the intelliSenseMode in the file c_cpp_properties.json shows this documentation popup.

It pretty much says that valid values have to be specified in the format <platform>-<compiler>-<architecture>. The older <compiler>-<architecture> variants are legacy modes and are converted automatically to the newer format based on the platform. So, some valid values can be

1. linux-gcc-x64
2. windows-msvc-x64
3. macos-clang-x64

But when I checked in the documentation here it says the following.

Conclusion

I would go with the contextual documentation since official documentation builds can lag behind.
