Append git's branch name to command prompt

Question

I wanted to use one of the Git-completion.bash features but I can\'t customize the look I\'d like to have. Here is relevant part of my .bash_profile:

source ~/.g         


        

Answer 1

Not sure, but vcprompt might solve it better for you?

Answer 2

The trick to get the quoting right is to have eveything double-quoted, except for $(__git_ps1 "(%s)"), which is single-quoted.

source ~/.git-completion.bash
function prompt
{
local WHITE="\[\033[1;37m\]"
local GREEN="\[\033[0;32m\]"
local CYAN="\[\033[0;36m\]"
local GRAY="\[\033[0;37m\]"
local BLUE="\[\033[0;34m\]"
export PS1="
${GREEN}\u${CYAN}@${BLUE}\h ${CYAN}\w"' $(__git_ps1 "(%s)") '"${GRAY}"
}
prompt

An alternative solution is to replace $( with \$( in the code in the question.

Background information: Two substitutions take place: first at export PS1="..." time, and later when the prompt is displayed. You want to execute __git_ps1 each time the prompt is displayed, so you have to make sure that the first substitution keeps $(...) intact. So you write either '$(...)' or "\$(...)". These are the two basic ideas behind the solutions I've proposed.
