  3. # agnoster's Theme - https://gist.github.com/3712874
  4. # A Powerline-inspired theme for ZSH
  5. #
  6. # # README
  7. #
  8. # In order for this theme to render correctly, you will need a
  9. # [Powerline-patched font](https://github.com/Lokaltog/powerline-fonts).
  10. # Make sure you have a recent version: the code points that Powerline
  11. # uses changed in 2012, and older versions will display incorrectly,
  12. # in confusing ways.
  13. #
  14. # In addition, I recommend the
  15. # [Solarized theme](https://github.com/altercation/solarized/) and, if you're
  16. # using it on Mac OS X, [iTerm 2](https://iterm2.com/) over Terminal.app -
  17. # it has significantly better color fidelity.
  18. #
  19. # If using with "light" variant of the Solarized color schema, set
  20. # SOLARIZED_THEME variable to "light". If you don't specify, we'll assume
  21. # you're using the "dark" variant.
  22. #
  23. # # Goals
  24. #
  25. # The aim of this theme is to only show you *relevant* information. Like most
  26. # prompts, it will only show git information when in a git working directory.
  27. # However, it goes a step further: everything from the current user and
  28. # hostname to whether the last call exited with an error to whether background
  29. # jobs are running in this shell will all be displayed automatically when
  30. # appropriate.
  31. ### Segment drawing

  42. # the code points they use for their special characters. This is the new code point.
  43. # If this is not working for you, you probably have an old version of the
  44. # Powerline-patched fonts installed. Download and install the new version.
  45. # Do not submit PRs to change this unless you have reviewed the Powerline code point
  46. # history and have new information.
  47. # This is defined using a Unicode escape sequence so it is unambiguously readable, regardless of
  48. # what font the user is viewing this source code in. Do not replace the
  49. # escape sequence with a single literal character.
