Vim

Vim editor is my daily driver when it comes to editing files in headless environment. Vim gains advantage because it can be customized with plugins, tons of keyboard shortcuts (though not quite easy to learn), and a lot of resources to gain mastery using it.

Here is my Vim configuration file, the ~/.vimrc.

" Specify directory
call plug#begin('~/.vim/plugged')

This ~/.vimrc config assumes the following (plus few tricks):

Plugins

I forgot where & when I stole this .vimrc and I implemented them long ago. As of writing today (9 Apr 2018), I added a few more lines. I added plugins Goyo.vim for zen-mode Markdown editing, ctrlp.vim for quick search (within a folder), vim-colorschemes so that I can use badwolf theme, undotree so I can see the undo stack. Also this day, I added 8 custom keybindings utilizing the <space> key extensively.

For a full cheat sheet, go here.

vim-surround

This is a plugin and it is a bit pain to use at first, that is why I have a special section for that here.

Spellchecking

To enable spellcheck, I do this:

:set spell spelllang=en_us

So in our ~/.vimrc, I now have this:

nnoremap <space>ss :set spell spelllang=en_us<cr> 

Which enables me to just hit Space followed rapidly by s twice to enable spellchecking.

To fix spelling error, go to that word first and toggle Insert Mode, then press Ctrl-x-s to invoke the spelling suggestions.
