frnhr/.bash_profile

Thank you so much for this. I held on as long as I could until they finally killed the feature officially, but I spend so much time bouncing between environments that this is essential. I really appreciate it!

thanks sir!

thank you so much!

may I ask how to update this script to do not modify prompt when using the system python??

Hallellullay! Thank you very much

@changchichung Almost a year later (I failed to notice the question, sorry), the answer is to just change this line:

    [ "$VENV_NAME" == "$GLOBAL_NAME" ] && COLOR="$RED"

into:

    [ "$VENV_NAME" == "$GLOBAL_NAME" ] && COLOR=""

This will make the hook do nothing when using the default python env.

For people coming to this using fish, I somewhat replicated this functionality with this in my config.fish:

# pyenv init
if command -v pyenv 1>/dev/null 2>&1
  pyenv init - | source
end

set -gx PYENV_VIRTUALENV_DISABLE_PROMPT 1

function pyenvVirtualenvUpdatePrompt
    set RED 'red'
    set GREEN 'green'
    set BLUE 'blue'
    set RESET 'normal'
    [ -z "$PYENV_VIRTUALENV_ORIGINAL_PS1" ] && set -x PYENV_VIRTUALENV_ORIGINAL_PS1 "$PS1"
    [ -z "$PYENV_VIRTUALENV_GLOBAL_NAME" ] && set -x PYENV_VIRTUALENV_GLOBAL_NAME "(pyenv global)"
    set VENV_NAME (pyenv version-name)
    set VENV_NAME "(echo $VENV_NAME | sed 's:/*\$::')"
    set GLOBAL_NAME "$PYENV_VIRTUALENV_GLOBAL_NAME"

    # non-global versions:
    set COLOR "$BLUE"
    # global version:
    test "$VENV_NAME" = "$GLOBAL_NAME" && set COLOR "$RED"
    # virtual envs:
    test "(echo $VIRTUAL_ENV | sed 's:/*\$::')" = "$VENV_NAME" && set COLOR "$GREEN"
    set_color $COLOR; echo (pyenv version-name)
end

Note that I'm using this guide for fish installation of pyenv, so no guarantee this will work with Oh My Fish. Next you edit your fish prompt with funced fish_prompt and put this:

fish_prompt> function fish_prompt --description 'Write out the prompt'
                 .......
                 echo -n -s (prompt_login)' ' (set_color $color_cwd) (prompt_pwd) $normal (fish_vcs_prompt) $normal " " (pyenvVirtualenvUpdatePrompt) $normal " "$prompt_status $suffix " "
             end

NOTE: You may have to put this whole function in ~/.config/fish/functions/fish_prompt.fish in order to make it persist across reboots.

The key is putting in the space after the VCS prompt, followed by the function we initialized, and then the $normal color for whatever comes after it in fish. After a refresh, with pyenv local 3.6.15 your prompt should look like:

user@srv-1001 /m/c/U/h/D/s/G/tls (oop) 3.6.15>

Hope this helps everyone.
