# This file defines configuration options for Powerlevel10k ZSH theme that will make your prompt
# lightweight and sleek, unlike the default bulky look. You can also use it with Powerlevel9k -- a
# great choice if you need an excuse to have a cup of coffee after every command you type.
#
# This is how it'll look:
# https://raw.githubusercontent.com/romkatv/dotfiles-public/master/dotfiles/purepower.png.
#
# Pure Power needs to be installed in addition to Powerlevel10k, not instead of it. Pure Power
# defines a set of configuration parameters that affect the styling of Powerlevel10k; there is no
# code in it.
#
#                         PHILOSOPHY
#
# This configuration is made for those who care about style and value clear UI without redundancy
# and tacky ornaments that serve no function.
#
#   * No overwhelming background that steals attention from real content on your screen.
#   * No redundant icons. A clock icon next to the current time takes space without conveying any
#     information. This is your personal prompt -- you don't need an icon to remind you that the
#     segment on the right shows current time.
#   * No separators between prompt segments. Different foreground colors are enough to keep them
#     visually distinct.
#   * Bright colors for important things, low-contrast colors for everything else.
#   * No needless color switching. The number of stashes you have in a git repository is always
#     green. Since its meaning is the same in a clean and in a dirty repository, it doesn't change
#     color.
#   * Works with any font.
#
#                         LEFT PROMPT
#
#   * Your current directory is bright blue when it's writable and brownish when not.
#   * The prompt symbol on the left is '❮' when vicmd keymap is active and '❯' otherwise. It's green
#     if the last command has succeeded and red if it has failed.
#   * Git prompt colors:
#     * Grey: prompt is refreshing in the background (happens only in large repositories).
#     * Green: clean (no stated or unstaged changes and no untracked files).
#     * Yellow: dirty (some stated or unstaged changes).
#     * Teal: some untracked files but otherwise clean (no staged or unstaged changes).
#   * Git prompt icons:
#     * '@12345678' (git prompt color): detached HEAD at commit 12345678.
#     * 'my-feature' (git prompt color): on branch my-feature.
#     * 'my-feature|master' (git prompt color): on branch my-feature tracking remote branch master.
#     * '#my-release' (git prompt color): on tag my-release.
#     * '+' (yellow): staged changes.
#     * '!' (yellow): unstaged changes.
#     * '?' (teal): untracked files.
#     * '⇡42' (green): 42 commits ahead of remote.
#     * '⇣42' (green): 42 commits behind remote.
#     * '*42' (green): 42 stashes.
#
#                        RIGHT PROMPT
#
#   * Error code with an optional signal name of the last command if it failed, in red.
#   * Last command execution time (in seconds).
#   * '⇶' if you have background jobs.
#   * user@host in bright yellow if root, grey otherwise.
#   * If you type `custom_rprompt() { echo 'message' }` in your terminal, you'll get 'message' shown
#     on the right. Useful for integration with your scripts that change some sort of
#     state/environment.
#
#                       INSTALLATION
#
# 1. Copy this file to your home directory.
#
#    ( cd && curl -fsSLO https://raw.githubusercontent.com/romkatv/dotfiles-public/master/.purepower )
#
# 2. Source the file from ~/.zshrc.
#
#    echo 'source ~/.purepower' >>! ~/.zshrc
#
# 3. Enable Powerlevel10k ZSH theme. The easiest way is this:
#
#    git clone https://github.com/romkatv/powerlevel10k.git ~/powerlevel10k
#    echo 'source ~/powerlevel10k/powerlevel10k.zsh-theme' >>! ~/.zshrc
#
# If you are using a plugin manager, see https://github.com/romkatv/powerlevel10k for installation
# options.
#
#                       CONFIGURATION
#
# You can set PURE_POWER_MODE before sourcing ~/.purepower to restrict the range of used characters.
#
#   * PURE_POWER_MODE=fancy     use unicode characters in the prompt (default)
#   * PURE_POWER_MODE=portable  use only ascii characters in the prompt
#
# You can switch mode on the fly by setting PURE_POWER_MODE and executing zsh. Useful when you end
# up in a prehistoric environment and see gibberish on your screen.
#
#   PURE_POWER_MODE=portable exec zsh  # switch to portable mode
#   PURE_POWER_MODE=fancy    exec zsh  # switch to fancy mode
#
# To automatically switch to portable mode when logging in from a terminal that doesn't support
# unicode, put the following incantation in your ~/.zshrc.
#
#   [[ $TERM == xterm* ]] || : ${PURE_POWER_MODE:=portable}
#   source ~/.purepower
#
# To configure what gets shown in the prompt, edit ~/.purepower. See
# https://github.com/romkatv/powerlevel10k/blob/master/README.md#installation-and-configuration for
# configuration options. Prompt configuration is a deeply personal affair, so take your time to
# craft the right prompt just for you. The stock configuration is merely a starting point, a source
# of inspiration, a frame for your own creation. Mercilessly slash everything of little value to
# you. Don't care how long commands take to execute? Get rid of command_execution_time segment!
# Boldly mold prompt pieces useful to you to ensure a perfect fit to your workflow and aesthetic
# preferences. Take full advantage of powerlevel over 9k!
#
# Remember that colors looks differently in different terminals. Use this script to choose what
# works best for you.
#
#   for i in {0..255}; do print -P "%F{${(l:3::0:)i}}${(l:3::0:)i} TEST%f"; done
#
# Keep in mind that some prompt segments can appear and disappear depending on the state of your
# environment. Make sure colors work well in every situation. Neighboring segments should always
# have distinct colors.
#
# Try different fonts. Pure Power doesn't use esoteric symbols even in fancy mode and thus doesn't
# require a patched font. Any monospace font will do, although some are notoriously bad at
# displaying non-ascii symbols in terminals.
#
# If you are using Pure Power with Powerlevel9k rather than Powerlevel10k, you'll need to set
# PURE_POWER_USE_P10K_EXTENSIONS=0 before sourcing ~/.purepower or you'll see gibberish in your left
# prompt. This option will turn off vi keymap integration, so your prompt symbol will always be '❯'.
# Your prompt will also be 10-100 times slower with Powerlevel9k. This is not the fault of Pure
# Power. Powerlevel9k is slow with any styling.
