First of all, congrats for the awesome theme.
I've installed the nerd fonts from brew on Mac and chose the automatic path for the powerline-pills-zsh.
The result was a mess here, lol:

Could you help me?

There should be a pill containing Python's version.

• rbenv
• pyenv
• nvm
• Long path shortening
• Host

Welcome,
When I run ./install.sh I have the following error:
mkdir: /themes: Permission denied
cp: /themes: Permission denied

I copy manual theme to my themes folder, but when I reload terminal window
I have the following error:
Traceback (most recent call last):
ruby: No such file or directory -- /lib/powerline_pills.rb (LoadError)

Description

There should be a pill containing Ruby's version.

Description

A .gitignore file should be included, removing unnecessary files.

Description

There should be a pill containing NVM's version.

Description

There should be an integration with CircleCI to run automated tests.

Description

The project should use rspec and have unit tests.

The application throws an error when the terminal window is small enough to produce a negative amount of spaces for the first line.
The error is the following:

/home/lucasqueiroz/Documents/powerline-pills-zsh/lib/powerline_pills.rb:149:in `*': negative argument (ArgumentError)
	from /home/lucasqueiroz/Documents/powerline-pills-zsh/lib/powerline_pills.rb:149:in `<main>'

This can easily be fixed by not adding spaces if the length is negative.

Description

The code should be refactored to be easier to read, maintain and update.
