Issue
Recently, I give a try on oh my zsh, everything looks good till I try virtualevn and virtualenvwrapper. When I activate a virtualenv (e.g test), on normal bash, I will see the virtualenv name like:
(test)abc@abc:
But when I switched to zsh, I cannot see virtualenv name. Even though, I alr add virtualenv and virtualenvwrapper in plugins of oh my zsh. I also checked the activate file of my virtualenv, it contains:
f [ -z "${VIRTUAL_ENV_DISABLE_PROMPT-}" ] ; then
_OLD_VIRTUAL_PS1="$PS1"
if [ "x" != x ] ; then
PS1="$PS1"
else
PS1="(`basename \"$VIRTUAL_ENV\"`) $PS1"
fi
export PS1
fi
Is it because the comparision ["x" != x] return true?
Updated: I tried to echo $PS1 in activate file, and got this:
(test) %{$fg[magenta]%}%n%{$reset_color%}%{$fg[cyan]%}@%{$reset_color%}%{$fg[yellow]%}%m%{$reset_color%}%{$fg[red]%}:%{$reset_color%}%{$fg[cyan]%}%0~%{$reset_color%}%{$fg[red]%}|%{$reset_color%}%{$fg[cyan]%}⇒%{$reset_color%}
It seems the $PS1 is correct, but when I echo $PS1 in the terminal, the (test) is gone. It seems the $PS1 is override by something else!
Solution
Found the problem, it's due to the theme. The theme I used in the above case is pygmalion, it won't allow u to change $PS1.
After changed to robbyrussell theme, I can change $PS1 in terminal, but still cannot see the virtualenv name. After a while debugging, I found that by default the virtualenv plugin of oh my zsh disable the prompt:
# disables prompt mangling in virtual_env/bin/activate
export VIRTUAL_ENV_DISABLE_PROMPT=1
So just comment out the line in virtualenv plugin, problem solved.
