# agnoster's Theme - https://gist.github.com/3712874
|
||||||
|
# A Powerline-inspired theme for BASH
|
||||||
|
#
|
||||||
|
# (Converted from ZSH theme by Kenny Root)
|
||||||
|
# https://gist.github.com/kruton/8345450
|
||||||
|
#
|
||||||
|
# Updated & fixed by Erik Selberg erik@selberg.org 1/14/17
|
||||||
|
# Tested on MacOSX, Ubuntu, Amazon Linux
|
||||||
|
# Bash v3 and v4
|
||||||
|
#
|
||||||
|
# # README
|
||||||
|
#
|
||||||
|
# In order for this theme to render correctly, you will need a
|
||||||
|
# [Powerline-patched font](https://gist.github.com/1595572).
|
||||||
|
# I recommend: https://github.com/powerline/fonts.git
|
||||||
|
# > git clone https://github.com/powerline/fonts.git fonts
|
||||||
|
# > cd fonts
|
||||||
|
# > install.sh
|
||||||
|
|
||||||
|
# In addition, I recommend the
|
||||||
|
# [Solarized theme](https://github.com/altercation/solarized/) and, if you're
|
||||||
|
# using it on Mac OS X, [iTerm 2](http://www.iterm2.com/) over Terminal.app -
|
||||||
|
# it has significantly better color fidelity.
|
||||||
|
|
||||||
|
# Install:
|
||||||
|
|
||||||
|
# I recommend the following:
|
||||||
|
# $ cd home
|
||||||
|
# $ mkdir -p .bash/themes/agnoster-bash
|
||||||
|
# $ git clone https://github.com/speedenator/agnoster-bash.git .bash/themes/agnoster-bash
|
||||||
|
|
||||||
|
# then add the following to your .bashrc:
|
||||||
|
|
||||||
|
# export THEME=$HOME/.bash/themes/agnoster-bash/agnoster.bash
|
||||||
|
# if [[ -f $THEME ]]; then
|
||||||
|
# export DEFAULT_USER=`whoami`
|
||||||
|
# source $THEME
|
||||||
|
# fi
|
||||||
|
|
||||||
|
#
|
||||||
|
# # Goals
|
||||||
|
#
|
||||||
|
# The aim of this theme is to only show you *relevant* information. Like most
|
||||||
|
# prompts, it will only show git information when in a git working directory.
|
||||||
|
# However, it goes a step further: everything from the current user and
|
||||||
|
# hostname to whether the last call exited with an error to whether background
|
||||||
|
# jobs are running in this shell will all be displayed automatically when
|
||||||
|
# appropriate.
|
||||||
|
|
||||||
|
# Generally speaking, this script has limited support for right
|
||||||
|
# prompts (ala powerlevel9k on zsh), but it's pretty problematic in Bash.
|
||||||
|
# The general pattern is to write out the right prompt, hit \r, then
|
||||||
|
# write the left. This is problematic for the following reasons:
|
||||||
|
# - Doesn't properly resize dynamically when you resize the terminal
|
||||||
|
# - Changes to the prompt (like clearing and re-typing, super common) deletes the prompt
|
||||||
|
# - Getting the right alignment via columns / tput cols is pretty problematic (and is a bug in this version)
|
||||||
|
# - Bash prompt escapes (like \h or \w) don't get interpolated
|
||||||
|
#
|
||||||
|
# all in all, if you really, really want right-side prompts without a
|
||||||
|
# ton of work, recommend going to zsh for now. If you know how to fix this,
|
||||||
|
# would appreciate it!
|
||||||
|
|
||||||
|
# note: requires bash v4+... Mac users - you often have bash3.
|
||||||
|
# 'brew install bash' will set you free
|
||||||
|
