For C++ development, the “VimForCpp” script can set up a ready‑made IDE‑like environment with a single command:

curl -sLf https://gitee.com/HGtz2222/VimForCpp/raw/master/install.sh -o ./install.sh && bash ./install.sh

Note: avoid running the script as root; it currently supports only CentOS 7 x86_64.
