No such shell function `zle-line-init' in a theme randomizer function

[trajano]

Similar to #3462 but created this new topic since this is specific to a aliae function I created and I just need a bit of troubleshooting

  - name: omp-theme
    value: |
      local theme_folder="$HOME/themes"
      if (command -v brew > /dev/null)
      then
        theme_folder=$(brew --prefix oh-my-posh)/themes
      fi
      local selected_theme

      if [ $# -eq 1 ]; then
        selected_theme="$theme_folder/$1.omp.json"
      else
        local themes=("$theme_folder"/*.omp.json)
        local theme_count=${#themes[@]}
        selected_theme=${themes[RANDOM % theme_count + 1]}
      fi

      if [ -f "$selected_theme" ]; then
        echo "$selected_theme"
        eval "$(oh-my-posh -c "$selected_theme" init {{.Shell}})"
      else
        echo "Theme file not found: $selected_theme"
      fi
    type: function
    if: match .Shell "bash" "zsh" match .OS "darwin" "linux"

For the most part it works, but it just gets this annoying

At the moment I dynamically create the function but I am not sure what the impact would be

  - name: omp-theme
    value: |
      local theme_folder="$HOME/themes"
      if (command -v brew > /dev/null)
      then
        theme_folder=$(brew --prefix oh-my-posh)/themes
      fi
      local selected_theme

      if [ $# -eq 1 ]; then
        selected_theme="$theme_folder/$1.omp.json"
      else
        local themes=("$theme_folder"/*.omp.json)
        local theme_count=${#themes[@]}
        selected_theme=${themes[RANDOM % theme_count + 1]}
      fi

      if [ -f "$selected_theme" ]; then
        echo "$selected_theme"
        if ! (command -v zle-line-init > /dev/null)
        then
          zle-line-init() {
          }
        fi
        eval "$(oh-my-posh -c "$selected_theme" init {{.Shell}})"
      else
        echo "Theme file not found: $selected_theme"
      fi
    type: function
    if: match .Shell "bash" "zsh" match .OS "darwin" "linux"

I honestly have no idea. This error only occurred when people use init twice inside zsh.
