+# 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
+#
+# V0.4.1
+#
+
+# 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.
+
+# Make sure this is bash that's running and return otherwise.

+# ab+simple theme
+
+this theme needs a Powerline-patched font to render correctly. i recommend: https://github.com/adi1090x/termux-style
+
+a colorful theme based on agnoster theme, made shorter and simpler.
+
+added title support for termux and random dates for fun.
+
+the aim of this theme is to only show you *relevant* information.
+
+ie: it will only show git information when in a git working directory.
+
+also, everything from the current user and hostname to whether the last call exited with an error or whether background jobs are running in this shell will all be displayed automatically when appropriate.
