RVM showing Ruby version in ZSH

Question

I just installed rvm to upgrade ruby using the method outlined here. After installation my zsh instance now always displays rvm:ruby-2.3.0, as per this image:

I'd rather it not appear but I'm having trouble finding where it's set, any thoughts? It's pretty annoying.

Thanks!

Your prompt is set in a .zsh-theme file that is specified in your .zshrc file in your home directory.

Changing to another theme:

If you want to change your prompt to a preexisting one, open your .zshrc file with your favorite text editor. Your can find your .zshrc in ~/.zshrc. When you open that file you will see a line that looks something like this: ZSH_THEME="gallois". (It looks like you're using gallois)

This is the line that you should change if you want to change your entire prompt. For example, change your this from ZSH_THEME="gallois" to ZSH_THEME="dallas" to change to the preexisting dallas theme. Click here For a list of all the default themes and what they look like. These themes are located in ~/.oh-my-zsh/themes.

You should then run . ~/.zshrc to source zsh and you will see the new prompt.

Editing the gallois theme to remove the right prompt

These themes are located in ~/.oh-my-zsh/themes. I would recommend copying the gallois.zsh-theme file and making some other file like yourname.zsh-theme. In the theme file you can remove the right prompt entirely by removing the line below this comment:

# Combine it all into a final right-side prompt
RPS1='$(git_custom_status)$(ruby_prompt_info) $EPS1'

You should probably remove this from the theme file as well for good measure:

# RVM component of prompt
ZSH_THEME_RVM_PROMPT_PREFIX="%{$fg[red]%}["
ZSH_THEME_RVM_PROMPT_SUFFIX="]%{$reset_color%}"

#Customized git status, oh-my-zsh currently does not allow render dirty status before branch
git_custom_status() {
  local cb=$(git_current_branch)
  if [ -n "$cb" ]; then
    echo "$(parse_git_dirty)%{$fg_bold[yellow]%}$(work_in_progress)%{$reset_color%}$ZSH_THEME_GIT_PROMPT_PREFIX$(git_current_branch)$ZSH_THEME_GIT_PROMPT_SUFFIX"
  fi
}

Keep in mind, this will also remove any descriptions about git repos from your prompt. You should then run . ~/.zshrc to source zsh and you will see the new prompt.

Editing the gallois theme to only remove the ruby prompt

These themes are located in ~/.oh-my-zsh/themes. I would recommend copying the gallois.zsh-theme file and making some other file like yourname.zsh-theme. In the theme file you can remove just the rvm prompt by removing a portion of this line:

# Combine it all into a final right-side prompt
RPS1='$(git_custom_status)$(ruby_prompt_info) $EPS1'

If you just remove the $(ruby_prompt_info) portion so that it looks like this:

# Combine it all into a final right-side prompt
RPS1='$(git_custom_status) $EPS1'

Then you can skip to the end and only remove the rvm portion of the prompt. I would also recommend removing these lines to avoid cluttering the theme file:

# RVM component of prompt
ZSH_THEME_RVM_PROMPT_PREFIX="%{$fg[red]%}["
ZSH_THEME_RVM_PROMPT_SUFFIX="]%{$reset_color%}"

You should then run . ~/.zshrc to source zsh and you will see the new prompt.

if, like me, you were going nuts making changes to your theme file that were not reflected in the actual shell, check to see if your theme is being loaded from a custom folder instead of the themes folder. – Fogle

If, like me, you ended up here because of this problem with the powerlevel10k theme, do the following to disable the rvm segment:

1. Open ~/.p10k.zsh

2. Find the line:

   rvm                     # ruby version from rvm (https://rvm.io)
   

3. Comment it out:

   # rvm                     # ruby version from rvm (https://rvm.io)
   

4. Open a new terminal

my codespaces in github all of a sudden were showing the ruby version, so thanks for the pro tip here to comment this line out. – Twentieth

Answer 3

Another way to hide the ruby version information is to override the ruby_prompt_info() function used to determine what gets included in the prompt.

To do this, edit your ~/.zshrc and add the following after $HOME/.rvm/scripts/rvm has been sourced:

# hide ruby version from ps1
function ruby_prompt_info() { echo '' }

This is the way. – Survey

Modifying the theme just gives me the ick. I added another answer based on yours too, in case you don't want to outright disable it. – Survey

Answer 4

Building on @Keith Hughitt's answer:

You can make the ruby version conditional on the existence on an .rvnrc file if you like. That's what I did:

# I want to modify ruby_prompt_info function to only show the ruby version when inside a
# dir with a .rvmrc file
# First I need to save the original function, this requires eval to get the
# function declaration before I override it, otherwise it becomes cyclic
eval "__ruby_prompt_info() { $(declare -f ruby_prompt_info | sed '1d;$d') }"
# Now I can override to wrap the original function in a check for .rvmrc
function ruby_prompt_info() {
  if [[ -f .rvmrc ]]; then
    __ruby_prompt_info
  fi
}
