# This theme was inspired by agnoster's Theme:

# Please see the README file located in the source repository for full docs.
# What follows is a brief list of the settings variables used by this theme.
# You should define these variables in your `~/.zshrc`.
#
# Customize which segments appear in which prompts (below is also the default):
#   POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(context dir rbenv vcs)
#   POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS=(status history time)
#
# Set your Amazon Web Services profile for the `aws` segment:
#   export AWS_DEFAULT_PROFILE=<profile_name>
#
# Set your username for the `context` segment:
#   export DEFAULT_USER=<your username>
#
# Customize the format of the time segment. Example of reverse format:
#   POWERLEVEL9K_TIME_FORMAT='%D{%S:%M:%H}'
#
# Show the hash/changeset string in the `vcs` segment:
#   POWERLEVEL9K_SHOW_CHANGESET=true
# Set the length of the hash/changeset if enabled in the `vcs` segment:
#   POWERLEVEL9K_CHANGESET_HASH_LENGTH=6
#
# Make powerlevel9k a double-lined prompt:
#   POWERLEVEL9K_PROMPT_ON_NEWLINE=true
#
# Set the colorscheme:
#   POWERLEVEL9K_COLOR_SCHEME='light'
