vscode intelligense not working properly

[kyrpav]

Hello i am using vscode and i have an issue with the intelligence. I used sever versions of esp-idf this did not fix my problem i am currently using the 4.4 and my main issue is that i get recommendations from intelligence but when i go inside lets say a struct intelligence does not follow which means that if i have a struct name time and this had two variables sec and min then when i go to program and call it like:

Code: Select all

struct time t ={
	. //and use the intelligence
	};

Then intelligence shows what ever function or variable. If i start typing it slowly it shorts out but this means that everytime either i have to open the structs to check variable names or i have to remember.

Is there some setup in config that helps to fix this?

I am attaching a screenshot :

There could be many reasons why intellisense is not working. Here are some things to consider:

• In the source file you are modifying, can intellisense navigate to the correct header files when you click on them? Or are they underlined with red. Usually when intellisense cannot find a function from compile_commands.json and the source files includes, it will default to a naive approach and search for whatever source/header in your workspace that contains that same identifier.
• I don't think it's a good idea to use compile_commands.json AND "includePath" at the same time. Intellisense will also use "includePath" and I'm not sure if compile_commands.json takes precedence. Usually, compile_commands.json is the most accurate it lists the exact include paths required for each source file compiled.
• Is your struct declaration wrapped by some "#define CONFIG_..."?

In the "settings.json" file in the ".vscode" folder you need to set the "C_Cpp.intelliSenseEngine" property to "Default" instead of "Tag Parser":

Code: Select all

"C_Cpp.intelliSenseEngine": "Default"

However, in my case, with this option, IntelliSense only recognizes the headers after compiling the code. But it correctly expands the members of a structure.
