# find that omitting the -r from $PAGER but leaving it in place for the alias
# makes the screen output look less janky. In particular, with $PAGER being
# "less -r", git diff on-screen information doesn't start showing the first
# diff-output line.

# Set my prompt, using bash-prompt escapes and xterm text-coloring escapes.
#
# Some bash-prompt escapes:
# \d: date
# \h: hostname
# \H: hostname.domainname
# \j: number of background jobs
# \t: time
# \u: username
# \v: Bash version
# \V: Extended bash version
# \w: pwd
# \W: basename of pwd

# Simpler predecessors:
# export PS1='`whoami`:`pwd`% '
# export PS1='\u@\h:\W% '

# Example:
# kerl@sprax[tmp]  jobs=1 dirs=2$ 
# \_____________/  \___________/|
#     green             red     green

# Load xterm-style color variables:
. ~/.colorrc

# black white
# red   green   blue
# cyan  magenta yellow

# Notes:
#
# * show_jobs_and_dirs is just a C program which prints the "jobs=1 dirs=2" parts
#   when they are non-trivial.  I wrote it in C to avoid stack traces when ^C-ing
#   an empty prompt line.
#
# * The \[ \] around xterm escape sequences are important in shell prompts so that
#   the shell can properly compute the length of the prompt string which in turn
#   is essential to avoid screen-garbaging on history editing of long command lines.
#
# * $PS1ENV is for various work/project-specific things, typically set up in ~/.vars-site
#   which is in a private repo.
