" Sample config for pb071 students, available at fi.muni.cz/pb071
" ===============================================================
" Requires VIM-8.0 to enable linting, on aisa run:
"   $ module add vim-8.0
" However, the linting will fail silently, if version is older.
"
" Comes with plugin manager Plug: we added 2 colorschemes
" and linting plugin ALE, which uses clang-tidy and gcc
" to highlight some syntax errors.
"
" Install Plug first in bash:
"   $ curl -fLo ~/.vim/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
" Then run vim and install the plugins using command in normal mode:
"   :PlugInstall
"
" Most of the settings come from vimconfig.com.
" We added few handy key mappings:
"
" Ctrl+Up/Down	    Move line or a block of selected lines
" Ctrl+j/k
" <leader>pp	    Toggle paste mode on and off
" <leader><cr>	    Disable search highlight
"
" <cr> is carriage return, "Enter"
" <leader> is backspace, "\", complete the combination in 1 second
