Playing with vim configuration for C++

What I got as a result:

The main features:

• embedded file system explorer
• syntax highlighting
• hotkeys for compiling/running C++ code

HOWTO:

1. Install vim

$ sudo yum install vim

2. Install pathogen.vim for easy installation of other plugins

$ mkdir -p ~/.vim/autoload ~/.vim/bundle && curl -LSso ~/.vim/autoload/pathogen.vim https://tpo.pe/pathogen.vim
$ vim ~/.vimrc

1 2 3 4

" pathogen.vim configuration execute pathogen#infect() syntax on filetype plugin indent on

3. Install NerdTree for exploring file system

$ cd ~/.vim/bundle
$ git clone https://github.com/scrooloose/nerdtree.git
$ vim ~/.vimrc

1 2 3 4 5

" NerdTree configuration "hotkey to open/close nerdtree map <C-n> :NERDTreeToggle<CR> "close nerdtree if there are no more opened file autocmd bufenter * if (winnr("quot;) == 1 && exists("b:NERDTreeType") && b:NERDTreeType == "primary") | q | endif

4. Add hotkeys for compiling/running C++ code

$ vim ~/.vimrc

1 2 3 4 5 6 7 8

" Add a hotkey to save and compile c++ code autocmd filetype cpp nnoremap <F4> :w <bar> exec '!g++ '.shellescape('%').' -o '.shellescape('%:r')<CR> " Add a hotkey to run c++ code nnoremap <F5> :exec '!./'.shellescape('%:r')<CR> " Add a hotkey to save, compile and run c++ code autocmd filetype cpp nnoremap <F6> :w <bar> exec '!g++ '.shellescape('%').' -o '.shellescape('%:r').' && ./'.shellescape('%:r')<CR>

My .vimrc content:

In plans:

• add code autocomplete (see YouCompleteMe plugin)
• add support for code debug (great article about GDB)
• play with code formatting
