git-bash: show email in Git Bash command prompt variable

Question

The command prompt in Git Bash displays the current branch name (with other information such as directory name, etc) as given below.

mylogin@SYSNAME MINGW64 ~/path/to/my/repo (master)
$

How can I include the repo user profile email along with the branch name? The email is the user.email of the repo; which can be found using the command git config user.email.

I would like to have this value git config user.email in my command prompt along with the branch name as given below.

mylogin@SYSNAME MINGW64 ~/path/to/my/repo (master|myemail@github.com)
$

Please note I have a windows system.

Apply the result of `git config user.email` to your `PS1` environment variable to obtain the email and `git rev-parse --abbrev-ref HEAD 2> /dev/null | tr -d '\n'` to obtain the current branch. — Lyubomyr Shaydariv, Jan 11 '17 at 08:51

Well... The MinGW approach slightly differs from a "usual" bash approach because it has a very rich script to generate the PS1 Bash variable. You just have to to the following (assuming you're using 64-bit too):

find /mingw64/share/git/completion/git-prompt.sh or (%YOUR_GIT_LOCATION%\mingw64\share\git\completion\git-prompt.sh);
modify the gitstring environment variable:
replace local gitstring="$c$b${f:+$z$f}$r$p"
with local gitstring="$c$b${f:+$z$f}$r$p|$(git config user.email)".

The diff between my original version and my version with the user.email setting:

diff --git a/git-prompt.sh.BAK b/git-prompt.sh
index 07b52be..2d63680 100644
--- a/git-prompt.sh.BAK
+++ b/git-prompt.sh
@@ -515,7 +515,7 @@ __git_ps1 ()
        fi

        local f="$w$i$s$u"
-       local gitstring="$c$b${f:+$z$f}$r$p"
+       local gitstring="$c$b${f:+$z$f}$r$p|$(git config user.email)"

        if [ $pcmode = yes ]; then
                if [ "${__git_printf_supports_v-}" != yes ]; then

Thanks Lyubomyr. It worked. I could see both branch and email in my git bash command prompt. — Vijey, Jan 12 '17 at 15:01
