  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://gist.github.com/1595572).
  10. #
  11. # In addition, I recommend the
  12. # [Solarized theme](https://github.com/altercation/solarized/) and, if you're
  13. # using it on Mac OS X, [iTerm 2](http://www.iterm2.com/) over Terminal.app -
  14. # it has significantly better color fidelity.
  15. #
  16. # # Goals
  17. #
  18. # The aim of this theme is to only show you *relevant* information. Like most
  19. # prompts, it will only show git information when in a git working directory.
  20. # However, it goes a step further: everything from the current user and
  21. # hostname to whether the last call exited with an error to whether background
  22. # jobs are running in this shell will all be displayed automatically when
  23. # appropriate.
  24. ### Segment drawing
  25. # A few utility functions to make it easy and re-usable to draw segmented prompts
  26. CURRENT_BG='NONE'
  27. SEGMENT_SEPARATOR='⮀'
  28. # Begin a segment
  29. # Takes two arguments, background and foreground. Both can be omitted,
  30. # rendering default background/foreground.
  31. prompt_segment() {
  32. local bg fg
  33. [[ -n $1 ]] && bg="%K{$1}" || bg="%k"
  34. [[ -n $2 ]] && fg="%F{$2}" || fg="%f"
  35. if [[ $CURRENT_BG != 'NONE' && $1 != $CURRENT_BG ]]; then
  36. echo -n " %{$bg%F{$CURRENT_BG}%}$SEGMENT_SEPARATOR%{$fg%} "
  37. else
  38. echo -n "%{$bg%}%{$fg%} "
  39. fi
  40. CURRENT_BG=$1
  41. [[ -n $3 ]] && echo -n $3
  42. }
  43. # End the prompt, closing any open segments
  44. prompt_end() {
  45. if [[ -n $CURRENT_BG ]]; then
  46. echo -n " %{%k%F{$CURRENT_BG}%}$SEGMENT_SEPARATOR"
  47. else
  48. echo -n "%{%k%}"
  49. fi
  50. echo -n "%{%f%}"
  51. CURRENT_BG=''
  52. }
  53. ### Prompt components
  54. # Each component will draw itself, and hide itself if no information needs to be shown
  55. # Context: user@hostname (who am I and where am I)
  56. prompt_context() {
  57. local user=`whoami`
  58. if [[ "$user" != "$DEFAULT_USER" || -n "$SSH_CLIENT" ]]; then
  59. prompt_segment black default "%(!.%{%F{yellow}%}.)$user@%m"

  66. ZSH_THEME_GIT_PROMPT_DIRTY='±'
  67. dirty=$(parse_git_dirty)
  68. ref=$(git symbolic-ref HEAD 2> /dev/null) || ref="➦ $(git show-ref --head -s --abbrev |head -n1 2> /dev/null)"
  69. if [[ -n $dirty ]]; then
