Enabling certain plugins and options for .h and .cpp files only in Vim

Question

I have delimitMate installed for brace completion in Vim but it is running for all files, not just .h and .cpp files. DelimitMate has an option for disabling itself in the buffe

Answer 1

Reading the DelimitMate documentation at :h 'b:delimitMate_autoclose'. Add the following to your ~/.vimrc:

let g:delimitMate_autoclose = 0
augroup my_delimitmate
  autocmd!
  autocmd FileType cpp let b:delimitMate_autoclose = 1
augroup END

The idea is to turn off autoclose globally (g:) and turn it back on for specific buffers (b:).

Instead of the :autocmd and :augroup commands you can set b:loaded_delimitMate inside the appropriate ftplugin file. Example add the following to ~/.vim/after/ftplugin/cpp.vim:

let b:delimitMate_autoclose = 1

This method might be prefered if you want to keep your ~/.vimrc file clean or you already have many filetype specific commands, settings, or mappings.

Note: I do not use DelimitMate so I have not tested any of these settings.
