Adding virtualenv and conda support to Oh My Zsh Bira theme

oh-my-zsh-bira-conda-venv.md

Steps to add virtualenv and conda support to Bira theme

• Add the virtualenv plugin to ~/.zshrc and make sure these lines are in ~/.oh-my-zsh/plugins/virtualenv/virtualenv.plugin.zsh

  # disables prompt mangling in virtual_env/bin/activate
  export VIRTUAL_ENV_DISABLE_PROMPT=1
  
  #Disable conda prompt changes
  #https://conda.io/docs/user-guide/configuration/use-condarc.html#change-command-prompt-changeps1
  #changeps1: False
  `conda config --set changeps1 false`

• Add these two helper functions to ~/.oh-my-zsh/themes/bira.zsh-theme (add them near the top, not at the end)

  function venv_info {
      if [[ -n "$VIRTUAL_ENV" ]]; then
          echo "%{$fg[green]%}‹${VIRTUAL_ENV:t}›%{$reset_color%}"
      fi
  }
  
  function conda_info {
      if [[ -n "$CONDA_DEFAULT_ENV" ]]; then
          echo "%{$fg[green]%}‹${CONDA_DEFAULT_ENV}›%{$reset_color%}"
      fi
  }
  local venv='$(venv_info)'
  local conda='$(conda_info)'

• Add it to the prompt

  Look for the PROMPT variable in the same file and add ${conda} ${venv} to it (The order in which they should appear is your preference). It should look like this

  PROMPT="╭─${user_host} ${current_dir} ${rvm_ruby} ${git_branch} ${conda} ${venv}
  ╰─%B${user_symbol}%b "

• Source ~/.zshrc to see if changes have taken place

I'm using the jonathan theme , and all the solution above didn't work in jonathan because Jonathan has a different code structure from Bira . To display conda info in jonathan , just add the function "conda_info" to .oh-my-zsh/themes/jonathan.zsh-theme :

conda_prompt_info(){
  if [ -n "$CONDA_DEFAULT_ENV" ]; then
    echo -n "($CONDA_DEFAULT_ENV)"
  else
    echo -n "(base)"
  fi
}

As Jonathan has 2 lines of output and the first output line was filled by a function using "------" . If conda info displays in the first line , those "------" will be out of your screen . So :
add '${$(conda_prompt_info)}' to the SECOND LINE OF OUTPUT in the PROMPT . the PROMPT was devided into 2 parts by a empty line , so you can easily find where to add conda info . For me , I added it after the time info . My PROMPT is like

PROMPT=\'${PR_SET_CHARSET}${PR_STITLE}${(e)PR_TITLEBAR}\
${PR_CYAN}${PR_ULCORNER}${PR_HBAR}${PR_GREY}(\
${PR_GREEN}%${PR_PWDLEN}<...<%~%<<\
${PR_GREY})$(ruby_prompt_info)${PR_CYAN}${PR_HBAR}${PR_HBAR}${(e)PR_FILLBAR}${PR_HBAR}${PR_GREY}(\
${PR_CYAN}%(!.%SROOT%s.%n)${PR_GREY}@${PR_GREEN}%m:%l\
${PR_GREY})${PR_CYAN}${PR_HBAR}${PR_URCORNER}\

${PR_CYAN}${PR_LLCORNER}${PR_BLUE}${PR_HBAR}(\
${PR_YELLOW}%D{%H:%M:%S}\
${PR_LIGHT_BLUE}%{$reset_color%}$(git_prompt_info)$(git_prompt_status)${PR_BLUE})${$(conda_prompt_info)}${venv_prompt}${PR_CYAN}${PR_HBAR}\
${PR_HBAR}\
>${PR_NO_COLOUR} \'

I hope this will help someone too XD
