Can I use cppcheck when I execute :wq in Vim editor for c/c++

Question

I want to override wq/q/w!/w/q! to user defined command along with its functionality.

Example :

If I use :wq to exit, the command should do static code check of that particular c/c++ file and exit.

Please help me in this case.

Thanks in advance.

The built in solution to your problem is called an "autocommand" in Vim.

It is a way to invoke a command at a specific time like opening, saving or closing a buffer.

See :help autocmd for the full list

In your case, you should add to your .vimrc the following command

autocmd BufWritePre *.cpp,*.hpp !cppcheck %

• BufWritePre means 'before writing the buffer' (You can also use BufWrite or BufWritePost)
• *.cpp,*.hpp means the auto command will only be applied when saving cpp or hpp files. You can add c and h files if you want.
• % means 'path of the current buffer'
• cppcheck must be in your path

You are not overriding the defaut behaviour of 'w' but you are using 'hooks' to add custom commands.
