feat: Add elixir section

bradcypert commented 5 years ago

This PR adds in support for Elixir into SpaceFish. This matches parity of the feature in https://github.com/denysdovhan/spaceship-prompt

Description

Adds in a section for Elixir support into SpaceFish. It checks against iex, exenv and elixir to see if you have an elixir install and only shows in directories that contain mix.ex or other elixir files. It's configureable via the following options:

Variable	Default	Meaning
`SPACEFISH_ELIXIR_SHOW`	`true`	Show current Elixir version
`SPACEFISH_ELIXIR_PREFIX`	`$SPACEFISH_PROMPT_DEFAULT_PREFIX`	Prefix before the elixir section
`SPACEFISH_ELIXIR_SUFFIX`	`$SPACEFISH_PROMPT_DEFAULT_SUFFIX`	Suffix after the elixir section
`SPACEFISH_ELIXIR_SYMBOL`	`💧·`	Character to be shown before Elixir version
`SPACEFISH_ELIXIR_COLOR`	`magenta`	Color of Elixir section

Motivation and Context

This helps maintain the mission of absolute parity with Spaceship.

@matchai thanks for looking over my PR and showing me a more idiomatic way to handle the search of a string. I'm not 100% sure why tests would be getting a different version on Linux. As far as I know, the Linux image shouldn't have elixir preinstalled on it and it doesn't look like the travis.yml is adding any elixir stuff.

@halostatue You were right! I think I just needed to set a value for the Elixir version.
