How to clang-format LibreOffice code-base only for selected code piece(s) - VSCode

According to https://wiki.documentfoundation.org/Development/clang-format:

$ wget https://dev-www.libreoffice.org/bin/clang-format-5.0.0-linux64
$ chmod +x clang-format-5.0.0-linux64
$ sudo mkdir -p /opt/lo/bin/
$ sudo cp clang-format-5.0.0-linux64 /opt/lo/bin/clang-format

Then, to reformat the whole file:

$ /opt/lo/bin/clang-format -i path/to/thefile.cxx

We can reformat a file easily. But what if we want to do clang-format only for a specific code-piece(s) (e.g. a function, class, if-else …) instead?

On VSCode (Linux):

• File > Preferences > Settings.
• Search for clang-format.
• in C_Cpp: Clang_format_path section, set the path of the clang-format executable as /opt/lo/bin/clang-format.

For example, let’s only select the if statement here:

...
    for (PageIdToFileNameMap_Impl& rEntry : FileMap_Impl)
    {
        if    (        rEntry.m_nPageId == nPageId)
        {
            return OStringToOUString(/*...*/);
        }
    }
...

Then right click on the selection and select Format Selection:

Finally, formatting only for if statement should work:

...
    for (PageIdToFileNameMap_Impl& rEntry : FileMap_Impl)
    {
        if (rEntry.m_nPageId == nPageId)
        {
            return OStringToOUString(/*...*/);
        }
    }
...
