Make Vim look good

Overview

> For this step, it's best if you have iTerm2 on OS X or mobaXterm on
> Windows. If you're using Linux, I'll leave it up to you to choose a
> sensible terminal emulator.
>
> This step is also really long. Here's a TL;DR:

1. Change your terminal's preferences to use Solarized
2. Install a patched font
3. Make the appropriate changes to your vimrc
4. Uncomment the line with `g:airline_powerline_fonts`

In addition, depending on your machine, you may want to see the
Troubleshooting section at the end.

------------------------------------------------------------------------

Solarized

To make Vim look good, you can install extra color schemes. For the
purposes of this demo, I've chosen two: Solarized (the most widely used
color scheme) and Molokai (a port of the Textmate/Sublime color scheme).
Feel free to pick one by changing the

    colorscheme solarized

line to something else.

Solarized is a special kind of color scheme. For it to work properly,
you need to make changes in two places:

- Your ~/.vimrc
- Your terminal emulator's preferences (like iTerm2, MobaXterm, etc.)

For macOS, I recommend using iTerm2, and for Windows, I recommend
MobaXterm. If you're using one of these terminals, you already have
Solarized installed; you just need to select it from your preferences.
Otherwise, install a Solarized theme for your terminal emulator:

If you can't figure out how to do this for your terminal, just uncomment
the line that says

    let g:solarized_termcolors=256

Note that Solarized is one of many great colorschemes; feel free to
explore and find one you love!

Patched Fonts

We're also installing a plugin called vim-airline that makes Vim look
pretty awesome. It adds tons of information to your Vim and adds style
too. It works best if you have what's called a "patched font". There are
a number of patched fonts that you can install, but the one I recommend
is

    https://github.com/abertsch/Menlo-for-Powerline

Once you've downloaded all the .ttf files, change your default font in
your terminal emulator's preferences.

If you do manage to install a patched font, you can tell vim-airline to
use them by uncommenting the line that reads

    let g:airline_powerline_fonts = 1

------------------------------------------------------------------------

Troubleshooting

If you make all the changes here and nothing seems to be working, check
that you have this line in your ~/.bashrc:

    export TERM="xterm-256color"

Setting up Solarized and vim-airline is basically impossible on PuTTY.
Instead, you should go download mobaXterm, which is an SSH client that
lets you a) comes pre-installed with Solarized colors and b) lets you
choose a patched font:

    http://mobaxterm.mobatek.net/

For detailed installation instructions and a sneak peak at some of it's
more powerful features, see here

And while once upon a time I managed to get a patched font working with
MobaXterm, I haven't managed to get it to work since. Your mileage may
vary.
