Automatically grey out disabled code by Preprocessor Directives (#define)

[gonzalo]

Hello. I'm in the transition of porting my whole project from Platformio+Arduino to IDF VS Code Extension+IDF+Arduino

I miss a feature that I'm not sure if it's Platformio specific. In my project I configure how the code is compiled enabling and disabling #defines (preprocessor directives).

Previously when I commented out a #define VSCode automatically greyed out the code that was disabled by a preprocessor directive.

Now with this change to plain IDF+Arduino As A Component (using the VS Code extension), that functionality is lost. The IDE is not dinamically evaluating the preprocessor directives nor greying out code.

How can I recover that functionaliy? I can provide pictured if I wasn't enough clear with the explanation.

I've found the issue. Intellisense is configured differently in the VSCode IDF Extension default templeate than in Platformio.

Adding "compileCommands": "${workspaceFolder}/build/compile_commands.json" to .vscode/c_cpp_properties.json and changing C_Cpp.intelliSenseEngine to default in .vscode/settings.json did the trick!

Note: You have to build for this to work because the file compile_commands.json is generated during compilation.
