+# ab+simple theme
+
+This theme needs a Powerline-patched font to be rendered correctly. The original author of the theme recommends https://github.com/adi1090x/termux-style
+
+This is a colorful theme based on the agnoster theme, made shorter and simpler.
+
+The aim of this theme is to only show you relevant information:
+The git information will only be shown in a git working directory.
+Similarly, everything will be displayed automatically when appropriate,
+including the current user and the hostname,
+whether the last call exited with an error,
+and whether background jobs are running in this shell.

+# bash-preexec.sh -- Bash support for ZSH-like 'preexec' and 'precmd' functions.
+# https://github.com/rcaloras/bash-preexec
+#
+#
+# 'preexec' functions are executed before each interactive command is
+# executed, with the interactive command as its argument. The 'precmd'
+# function is executed before each prompt is displayed.
+#
+# Author: Ryan Caloras (ryan@bashhub.com)
+# Forked from Original Author: Glyph Lefkowitz
+#
+# V0.5.0
+#
+
+# General Usage:
+#
+#  1. Source this file at the end of your bash profile so as not to interfere
+#     with anything else that's using PROMPT_COMMAND.
+#
+#  2. Add any precmd or preexec functions by appending them to their arrays:
+#       e.g.
+#       precmd_functions+=(my_precmd_function)
+#       precmd_functions+=(some_other_precmd_function)
+#
+#       preexec_functions+=(my_preexec_function)
+#
+#  3. Consider changing anything using the DEBUG trap or PROMPT_COMMAND
+#     to use preexec and precmd instead. Preexisting usages will be
+#     preserved, but doing so manually may be less surprising.
+#
+#  Note: This module requires two Bash features which you must not otherwise be
+#  using: the "DEBUG" trap, and the "PROMPT_COMMAND" variable. If you override
+#  either of these after bash-preexec has been installed it will most likely break.
+
+# Tell shellcheck what kind of file this is.
+# shellcheck shell=bash
+
+# Make sure this is bash that's running and return otherwise.
+# Use POSIX syntax for this line:
+if [ -z "${BASH_VERSION-}" ]; then
