  24. # Enable caching:
  25. #
  26. # If you want to use the cache, set the followings in your .zshrc:
  27. #
  28. # zstyle ':completion:*' use-cache yes
  29. #
  30. #
  31. # Settings:
  32. #
  33. # - Show grunt file path:
  34. # zstyle ':completion::complete:grunt::options:' show_grunt_path yes
  35. #
  36. # - Cache expiration days (default: 7):
  37. # zstyle ':completion::complete:grunt::options:' expire 1
  38. #
  39. # - Not update options cache if target gruntfile is changed.
  40. # zstyle ':completion::complete:grunt::options:' no_update_options yes
  41. #
  42. # Note that if you change the zstyle settings,
  43. # you should delete the cache file and restart zsh.
  44. #
  45. # $ rm ~/.zcompcache/grunt
  46. # $ exec zsh
