If you are using vim on a constrained system (container or production system), you may not have the ability to setup vim plugin managers and plugins to mimic a full development environment.
However, with a few basic settings in ‘~/.vimrc’, you can get a reasonable rendering that will assist in troubleshooting.
" find list using: ls -l /usr/share/vim/vim*/colors colorscheme torte set paste set ruler " basic settings for yaml and python files autocmd FileType python setlocal ts=4 sts=4 sw=4 expandtab number autoindent autocmd FileType yaml setlocal ts=2 sts=2 sw=2 expandtab autoindent " folding can help troubleshoot indentation syntax set foldenable set foldlevelstart=20 set foldmethod=indent nnoremap <space> za
If there are already system-wide settings and you just want to override specific settings, you can use ~/.vimrc to source the “$VIMRUNTIME/defaults.vim” and then load values on top like:
echo -en 'source $VIMRUNTIME/defaults.vim\ncolorscheme torte\nset mouse=' | tee ~/.vimrc
make sure $VIMRUNTIME does not get evaluated by the shell when creating the file, this special variable needs to be evaluated by vim.
