relationship between browse.path and tag parsing

[jalanh11640]

Hi, I'm running into a problem where I don't see intellisense tag parsing a lot of my source files.

I'm running inside a dev container with cpptools v1.22.11 and vscode version 1.95.3. I have a "browse" configuration of the following.

"browse": {
    "limitSymbolsToIncludedHeaders": true,
    "path": [
    "${workspaceFolder}"
    ]
} 

With this setting, the only 'tag parsing file' lines I see in the C/C++ debug output are header files found underneath the compiler directory.

If I change the path to "${workspaceFolder}/**/*" then all my sources get parsed by the tag parser.

This seems to be reverse of what the browse.path help text indicates.

A list of paths to use for indexing and parsing of workspace symbols (for use by 'Go to Definition', 'Find All References', etc.). Searching on these paths is recursive by default. Specify * to indicate non-recursive search. For example, ${workspaceFolder} will search through all subdirectories while ${workspaceFolder}/* will not.

On a slightly different subject, is there a way to prevent tag parsing of some files in a given configuration? For example, I have a configuration called 'release'. In this configuration, I would like to ignore unit test files in '${workspaceFolder}/**/test/'.

Thanks,
Jeff

Yes, setting browse.path to ${workspaceFolder} should be recursively tag parsing the source files in there. If you set C_Cpp.loggingLevel to "Debug" you should see "Processing folder (recursive):" with your workspace folder root. I'm not sure why that wouldn't be happening...maybe logging could help explain it? You can prevent tag parsing by setting C_Cpp.files.exclude to some glob pattern that matches the folder such as

    "C_Cpp.files.exclude": {
        "**/test": true
    },

Thanks for the response Sean.

When the browse.path is set to "[ ${workspaceFolder} ]" this is the C/C++ debug output

It looks like 15 more files were discovered and Processing folder (non-recursive): /workspace was printed.

As for your answer to exclude files. That looks like that's for excluding files from the settings.json file? I was hoping there was a way to exclude files just for a specific c_cpp_properties.json configuration. I also have a 'unit_test' configuration where I would want "${workspaceFolder}/**/test" files to be parsed.

Thanks,
Jeff
