fish shell and powerline notes CLI config

💻 app, theme, powerline theme

In the screenshot above, i'm using:

• ⧉ iTerm2
• 🎨 Soft Era syntax theme for iTerm 2 (Soft Era is also available for other platforms)
• powerline-shell for the prompt
• this config for powerline-shell (note: that powerline shell config has color settings that may only look good with the Soft Era colors due to contrast)
• fish shell
• typeface: Dank Mono

🌈 rainbow welcome prompt

requires the ruby gem lolcat

fish config

• add this line to file .config/fish/config.fish:
  • set -gx PATH ~/.gem/ruby/2.3.0/bin $PATH
    • this will allow fish to run ruby gems with this version of ruby. this may be specific to my computer, and the path may need to be changed to fit your configuration or your version of ruby 🙃

my full .config/fish/config.fish file:

set -gx PATH ~/.gem/ruby/2.3.0/bin $PATH
function fish_prompt
    powerline-shell --shell bare $status
end

the greeting script for fish

file: .config/fish/functions/fish_greeting.fish

function fish_greeting
	for i in (seq 7)
    for i in (seq (tput cols))
      printf █
    end

  echo
  end | lolcat --freq=0.8 --spread (tput cols)
end
