[shivamChandra65]

hello everyone,
Please help me I am a beginner
I just switched to zsh and want to disable the powerline it is making shell loading slower. and also want to change the prompt.
I have added these line to .zshrc other settings are default.

# Use powerline
USE_POWERLINE="true"
# Source manjaro-zsh-configuration
if [[ -e /usr/share/zsh/manjaro-zsh-config ]]; then
  source /usr/share/zsh/manjaro-zsh-config
fi
# Use manjaro zsh prompt
if [[ -e /usr/share/zsh/manjaro-zsh-prompt ]]; then
  source /usr/share/zsh/manjaro-zsh-prompt
fi

export EDITOR=nvim
alias nv='nvim'

#coloured aliases
	alias ls='ls --color=auto'
	alias grep='grep --colour=auto'
	alias egrep='egrep --colour=auto'
	alias fgrep='fgrep --colour=auto'

# vi mode
bindkey -v
export KEYTIMEOUT=1

# Enable searching through history
#bindkey '^R' history-incremental-pattern-search-backward

# Edit line in vim buffer ctrl-v
autoload edit-command-line; zle -N edit-command-line
bindkey '^v' edit-command-line
# Enter vim buffer from normal mode
autoload -U edit-command-line && zle -N edit-command-line && bindkey -M vicmd "^v" edit-command-line

# Use vim keys in tab complete menu:
#bindkey -M menuselect 'h' vi-backward-char
#bindkey -M menuselect 'j' vi-down-line-or-history
#bindkey -M menuselect 'k' vi-up-line-or-history
#bindkey -M menuselect 'l' vi-forward-char
#bindkey -M menuselect 'left' vi-backward-char
#bindkey -M menuselect 'down' vi-down-line-or-history
#bindkey -M menuselect 'up' vi-up-line-or-history
#bindkey -M menuselect 'right' vi-forward-char

# Fix backspace bug when switching modes
bindkey "^?" backward-delete-char


# Change cursor shape for different vi modes.
function zle-keymap-select {
  if [[ ${KEYMAP} == vicmd ]] ||
     [[ $1 = 'block' ]]; then
    echo -ne '\e[1 q'
  elif [[ ${KEYMAP} == main ]] ||
       [[ ${KEYMAP} == viins ]] ||
       [[ ${KEYMAP} = '' ]] ||
       [[ $1 = 'beam' ]]; then
    echo -ne '\e[5 q'
  fi
}
zle -N zle-keymap-select
zle-line-init() {
    zle -K viins # initiate `vi insert` as keymap (can be removed if `bindkey -V` has been set elsewhere)
    echo -ne "\e[5 q"
}
zle -N zle-line-init
echo -ne '\e[5 q' # Use beam shape cursor on startup.
preexec() { echo -ne '\e[5 q' ;} # Use beam shape cursor for each new prompt.

You can set
USE_POWERLINE="false"
to turn off powerline. And also comment the lines in #Use manjaro zsh prompt section to turn off manjaro zsh prompt. Then set the PROMPT variable as you like or install any other prompt.
