This is Vim syntax files with C++11 support. They are forked from vim-jp/vim-cpp and have support fo syntax highlighting of embeded ChaiScript.
To enable syntax highlighting wrap your embedded script in raw string literals as such:
std::string = R"chaiscript(
// some script
)chaiscript";c.vim is based on Bram Moolenaar
Bram@vim.org and cpp.vim is based on Ken Shan ccshan@post.harvard.edu.
License of original files conform to author of them. Enhancement of changes

possible. But we contribute this changes to VIM.
